Solve the inequality 2(-3 + 5) + 2 ≥ -4(x - 2) - 3
Answer:
4≤x same as x ≥ 4
Step-by-step explanation:
First you need to apply the distributive property.
That means 2 times -3 and positive 5
The inequality should look like this:
-6+10+2≥-4(x-2)-3
You should then do the same but on the other side keeping the -6+10+2 the same and undisturbed
Should look like this:
-6+10+2≥-4x+8-3
After, solve all of it
Should be simplified to this:
6 ≥ -4x+5
Now subtract 5 from both sides
6-5 ≥ -4x
1 ≥ -4x
Since we are dividing the inequality rule said that we shall flip the sign if dividing or multiplying by a negative number.
So the answer should look like this:
x ≥ 4

Step-by-step explanation:
1. Since we know that Lila wants to use 1 cup of pretzels, we can multiply 1/2 x 1/2, which is 1.
2. Now that we multiplied 1/2 by 1/2, we have to multiply 1 1/4 by 1/2.
So 5/4 x 1/2 is 5/8.
3. Lila will need 5/8 cups of raisins.

a circle has a radius of 16in. find the length s of the arc intercepted by a central angle of π6 radians. do not round any intermediate computations, and round your answer to the nearest tenth.
The length of the arc intercepted by a central angle of π/6 radians in a circle with a radius of 16 inches is approximately 8.4 inches.
What is the length of the arc intercepted by a central angle of π/6 radians in a circle with a radius of 16 inches?To find the length s of the arc intercepted by a central angle of π/6 radians in a circle with a radius of 16 inches, we can use the formula for the length of an arc:
s = rθwhere s is the arc length, r is the radius of the circle, and θ is the central angle in radians.
Plugging in the values, we have:
s = 16 * π/6Now, we can calculate the length of the arc:
s = (16π/6) ≈ 8.4 inchesRounding to the nearest tenth, the length of the arc intercepted by a central angle of π/6 radians in a circle with a radius of 16 inches is approximately 8.4 inches.

The exponential growth of the deer population in the country can be calculated using the model T 70,000(1+07) where 70,000 is the initial deer population and.07 is the rate of growth. T is the total population after n years have passed. (a) Predict the total population after 4 yr The total population after 4 yr is about (Round to the nearest thousand as needed.) (b) If the initial population was 30,000 and the growth rate was .11, approximately how many deer would be present after 5 yr? After 5 yr approximately deer would be present. (Round to the nearest thousand as needed.)
(A) The total population of deer after 4 years is approximately 153,000.
(B) 64,000 deer would be present after 5 years.
(a) The total population of deer after 4 years can be predicted using the given model as T = 70,000(1+0.7)^4. Solving this equation, we get T ≈ 153,33. Therefore, the total population of deer after 4 years is approximately 153,000.
(b) If the initial population of deer is 30,000 and the growth rate is 0.11, then the total population of deer after 5 years can be calculated as T = 30,000(1+0.11)^5. Solving this equation, we get T ≈ 63,531. Therefore, approximately 64,000 deer would be present after 5 years.
Exponential growth is a mathematical concept that describes how a quantity increases exponentially over time. In this case, the deer population is growing exponentially with a given rate of growth. The equation T = 70,000(1+0.7)^4 is used to calculate the total population of deer after 4 years. Similarly, the equation T = 30,000(1+0.11)^5 is used to calculate the total population of deer after 5 years, given the initial population and growth rate. The solutions to these equations are approximations rounded to the nearest thousand, and they provide estimates of the expected deer population in the future.

From the angle of elevation in trigonometry, the distance that the snake need to launch in order to catch the frog is equals to the 1.078 feet.
We have a snake which looks to catch the frog. Angle of elevation when sanke look the frog on a log = 28°
Distance between sanke and bottom of log = 2 feet
We have to determine the distance that snake need to launch in order to catch the frog. If we consider scenario on drawing, it form a right angled triangle with one angle 28° and Adjective side = 2 feet. To calculate the opposite side, using tangent trigonometry ratio,
\(tan(\theta) = \frac{opposite \: side}{adjacent \: side} \)
Substitute all known values in above formula,
\(tan(28°) = \frac{opposite \ side}{2} \)
=> opposite side = 2 feet × tan(28°)
=> opposite side = 2 × 0.5317094 = 1.078 feet

By the above inequality, we have∫J ƒ(x) dx ≤ M|J|, ∫K ƒ(x) dx ≤ M|K|Adding both the equations and applying the triangle inequality, we get ∫I ƒ(x) dx ≤ M|J| + M|K|Hence, U(ƒ, P|I) - L(ƒ, P|I) ≤ M|J| + M|K|Here, P|I denotes the partition of I corresponding to the partition P. We haveU(ƒ, P|I) - L(ƒ, P|I) ≤ M|J| + M|K| < M(b - a) = M|I|We know that f is integrable on [0,1], which means that for every positive ε, there is a partition Pε of [0,1] such that U(ƒ, Pε) - L(ƒ, Pε) < εGiven ε > 0, we can apply this result to each of the two subintervals J and K.

Therefore, there must exist at least one value x € [0, 1] with ƒ(x) = 0.
(a) To show that there exist a', b' such that supæ¤[a', b'] ƒ(x) ≤ ɛ, we use proof by contradiction, which implies that there is no such a', b'. That is to say, for any a', b', sup æ¤[a', b'] ƒ(x) > ɛ.
We first pick any arbitrary ɛ > 0 and let a0 = a and b0 = b. Then divide the interval [a0, b0] into two subintervals [a1, (a0 + b0)/2] and [(a0 + b0)/2, b1] such that the supremum of ƒ(x) on the first subinterval is greater than ɛ/2, and the supremum of ƒ(x) on the second subinterval is greater than ɛ/2. Let (a2, b2) be the subinterval that has a larger supremum than the other. Repeating this process, we construct the nested sequence of intervals in this way: [a0, b0] → [a1, b1] → [a2, b2] → ... Let (an) and (b n) be the corresponding sequences of endpoints.
That is, an ≤ an+1 < bn+1 ≤ bn. Then we have supä[an, bn] ƒ(x) > ɛ for all n. This contradicts the fact that ƒ is integrable, and hence there exists a', b' such that supæ¤[a', b'] ƒ(x) ≤ ɛ. (b) Suppose for the sake of contradiction that ƒ(x) > 0 for all x. By part (a), we can find a sequence of nested intervals [a1, b1] ⊇ [a2, b2] ⊇ [a3, b3] ⊇ ... such that supæ¤[an, bn] ƒ(x) ≤ 1/n for all n. Since ƒ(x) > 0 for all x, we have limn→∞ supä[an, bn] ƒ(x) = 0 by the squeeze theorem.
However, this contradicts the fact that ∫0¹ ƒ(x) dx = 0, since for any n we have ∫an b n ƒ(x) dx ≥ supä[an, b n] ƒ(x) × (b n - an) ≥ (1/n) × (b n - an), and hence ∫0¹ ƒ(x) dx = limn→∞ ∫an b n ƒ(x) dx ≥ limn→∞ (1/n) × (b n - an) > 0, which is a contradiction.

Express 20cm to 15m
to the lowest form
Answer:
Step-by-step explanation:
To convert 20 cm to meters, we divide by 100, because 1 meter = 100 centimeters.
So, 20 cm = 20/100 m = 0.2 m
To convert 0.2 m to meters in the lowest form, we divide by 15, because 1 meter = 15 units.
So, 0.2 m = 0.2/15 m = 0.013 m
So the final answer is 0.013 m.

The partial derivatives ∂T/∂U and ∂U/∂T are approximately -7.548 and -6.416 respectively.
To calculate the partial derivatives ∂T/∂U and ∂U/∂T using implicit differentiation of the equation (TU−V)² ln(W−UV) = ln(13), we'll differentiate both sides of the equation with respect to T and U separately.
First, let's find ∂T/∂U:
Differentiating both sides of the equation with respect to U:
(2(TU - V)ln(W - UV)) * (T * dU/dU) + (TU - V)² * (1/(W - UV)) * (-U) = 0
Since dU/dU equals 1, we can simplify:
2(TU - V)ln(W - UV) + (TU - V)² * (-U) / (W - UV) = 0
Now, substituting the values T = 3, U = 4, V = 13, and W = 65 into the equation:
2(3 * 4 - 13)ln(65 - 3 * 4) + (3 * 4 - 13)² * (-4) / (65 - 3 * 4) = 0
Simplifying further:
2(-1)ln(53) + (-5)² * (-4) / 53 = 0
-2ln(53) + 20 / 53 = 0
To express this fraction in symbolic notation, we can write:
∂T/∂U = (20 - 106ln(53)) / 53
Substituting ln(53) = 3.9703 into the equation, we get:
∂T/∂U = (20 - 106 * 3.9703) / 53
= (20 - 420.228) / 53
= -400.228 / 53
≈ -7.548
Now, let's find ∂U/∂T:
Differentiating both sides of the equation with respect to T:
(2(TU - V)ln(W - UV)) * (dT/dT) + (TU - V)² * (1/(W - UV)) * U = 0
Again, since dT/dT equals 1, we can simplify:
2(TU - V)ln(W - UV) + (TU - V)² * U / (W - UV) = 0
Substituting the values T = 3, U = 4, V = 13, and W = 65:
2(3 * 4 - 13)ln(65 - 3 * 4) + (3 * 4 - 13)² * 4 / (65 - 3 * 4) = 0
Simplifying further:
2(-1)ln(53) + (-5)² * 4 / 53 = 0
-2ln(53) + 80 / 53 = 0
To express this fraction in symbolic notation:
∂U/∂T = (80 - 106ln(53)) / 53
Substituting ln(53) = 3.9703 into the equation, we get:
∂U/∂T = (80 - 106 * 3.9703) / 53
= (80 - 420.228) / 53
= -340.228 / 53
≈ -6.416
Therefore, the partial derivatives are:
∂T/∂U = -7.548
∂U/∂T = -6.416
Therefore, the values of ∂T/∂U and ∂U/∂T are approximately -7.548 and -6.416, respectively.

We can factor this equation as:
r(4r³ - 4r² + 3) = 0
Since r cannot be zero, we must solve the cubic equation:
4r³ - 4r² + 3 = 0
Using a numerical method or a computer program, we can find that one real root of this equation is approximately 0.8202.
Now that we know the value of r, we can use the difference between the largest and minor consequent to find the value of a. The largest consequent is ar², and the minor consequent is a, so we have:
ar² - a = 120
Substituting r = 0.8202, we get:
a(0.8202)² - a = 120
Simplifying, we get:
a = 120 / (0.6721)
a ≈ 178.63
Finally, we can calculate the sum of the antecedents:
a + ar + ar² = 178.63 + (178.63)(0.8202) + (178.63)(0.8202)²
Summing these terms, we get:
a + ar + ar² ≈ 445.31
Therefore, the sum of the antecedents is approximately 445.31

The difference between the weight of 3 gallons of liquid and a 5 pound brick is 19 pounds. Write an equation to represent this situation. What is the weight of 1 gallon of the liquid
Answer: 3g - 5 = 19 ; 8 pounds
Step-by-step explanation:
Given that :
Difference between weight of 3 gallons of a liquid and a brick that weighs 5 pounds = 19 pounds.
Mathematically,
Let one gallon of the liquid = g
Hence,
(3 × g) - 5pounds = 19 pounds
3g - 5 = 19
The weight of one gallon(g) of the liquid equals :
From the expression above :
3g - 5 = 19
3g = 19 + 5
3g = 24
Divide both sides by 3
3g/3 = 24 /3
g = 8 pounds
Hence, weight of 1 gallon of the liquid is 8 pounds.
For a research project, students are asked to study how often students at an online high school look at social
media while doing schoolwork.
1. Sofie decides to develop a survey.
(a) Give an example of a question she could ask on her survey.
(b) How could Sofie select a simple random sample of students to take her survey?
(c) She gives out 80 surveys but receives only 32 completed surveys. What are the sample and
population for Sofie’s research?
(d) Of the 32 students who completed surveys, 16 said they use social media while doing schoolwork. If
Sofie uses only the completed surveys, what conclusion could she make about the percent of all high
school students who use social media while doing schoolwork?
(a) Example question: "How often do you look at social media while doing schoolwork?
(b) Sofie can select a simple random sample of students by using a random number generator to assign a unique identification number to each student in the online high school.
(c) The sample for Sofie's research is the 32 completed surveys she received. These surveys represent the responses of a subset of the population. The population, in this case, refers to all the students at the online high school.
(d) If Sofie uses only the completed surveys, she can conclude that approximately 50% (16 out of 32) of the students who completed the survey reported using social media while doing schoolwork.
(a) Please select one of the following options: never, rarely, occasionally, frequently, or always."
(b) She can then use the random number generator again to select a specific number of students from the entire population of students, ensuring that each student has an equal chance of being selected. For example, if there are 500 students in total and Sofie wants a sample size of 50, she can generate 50 random numbers and select the corresponding students based on their identification numbers.
(d) However, it is important to note that this conclusion is specific to the sample of completed surveys and cannot be generalized to the entire population of high school students.
To make an inference about the percent of all high school students who use social media while doing schoolwork, Sofie would need a larger and more representative sample that covers a wider range of students in the online high school.
Additionally, she should consider potential biases in the sample, such as non-response bias if the students who chose not to complete the survey have different social media usage patterns compared to those who did respond.

Which of the following units could be used to measure Area? Select all that apply.
a) m2
b) in
c) cm2
d) sq. ft
e) mm
f) yd3
All the area measure units should have square above them.
For example:mm²cm²yd²in²m²km²ft²Hence, option A, C, D is correct.
Answer:
a) c) d)
Step-by-step explanation:
Length is a one-dimensional measure, therefore it is measured in single units.
⇒ m
⇒ cm
⇒ ft
The area of a shape is a two-dimensional quantity (e.g. length × width), therefore it is measured in square units.
⇒ m × m = m²
⇒ cm × cm = cm²
⇒ ft × ft = ft²
The volume of a shape is a three-dimensional quantity (e.g. length × width × height), therefore it is measured in cubic units.
⇒ m × m × m = m³
⇒ cm × cm × cm = cm³
⇒ ft × ft × ft = ft³
Therefore,
length = options b) e)area = options a) c) d)volume = option f)The diagram show the metal piece 10mm 14mm 30mm 8mm8mm

What is a cuboid?In terms of geometry, it is known as the six-faced hexahedron. Three dimensions make up its form.
It is given that, this diagram shows the dimensions of a metal piece used in a machine.
We have to calculate the volume of the metal piece.
A cuboid's volume is calculated by multiplying its three dimensions (width, length, and height) together.
The volume of the horizontal cuboid:
V = l × b × h
V= 30 ×8 × 8
V= 1920 mm³
The volume of the vertical cuboid:
breadth = 10 mm
Length = 14+8 = 22 mm
Height = 8 mm
V = l × b × h
V = 22 × 10 × 8
V= 1760 mm³
The volume of the metal piece is obtained as,
= 1920 + 1760
= 3680 mm³
Volume of metal piece = 3680 mm³
Thus, the volume of the metal piece will be 3680 mm³.
