Answer:

Answer A

Step-by-step explanation:

Evaluate f(x) = -2x^2 - 3 at each element in {-1, 2, 5}:

f(-1) = -2(-1)^2 - 3 = -5

f(2) = -11

f(5) = -53

These results match the outputs in Answer A.

Answer: The area is 24 square units.

Step-by-step explanation:

Things you need to use in this exercise:

Area of a circle = pi*r^2

r is the radius, equal to half the diameter.

Ok, in the image we can see 3 half-circles.

one has a diameter of 8 units: with area A (the left one)

other has a diameter of 6 units: with area B (the bottom one)

and the other has a diameter equal to the hypotenuse of the right triangle: with area C (the white semicircle that also includes the right triangle)

Now, you can think the shaded area as:

The sum of the areas of the half circles A and B, minus the area of the half-circle C, plus the area of the right triangle (because the white triangle is also included in the white semicircle)

So the area is:

A + B - C + area triangle

A = pi*(8/2)^2 = 3.14*4^2 = 50.24

B = pi*(6/2)^2 = 3.14*3^2 = 28.26

the area of the triangle is equal to:

T = 6*8/2 = 24

Now, to obtain the area of the white semicircle ( C) we need the hypotenuse of the triangle, so here we can use the Pythagorean's theorem:

H^2 = 8^2 +6^2

H = √(8^2 + 6^2) = 10

Then:

C = pi*(10/2)^2 = 3.14*5^2 = 78.5

Then the shaded area is:

Area = 50.24 + 28.26 + 24 - 78.5 = 24

Answer:

im not 100 percent sure but i think its 88

Step-by-step explanation:

if not i am sorry.

Answer:

88

Step-by-step explanation:

Write 110% as 110/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

110/100  of 80 =  110 /100 x 80

Therefore, the answer is 88

If you are using a calculator, simply enter 110÷100×80 which will give you 88 as the answer.

There are no reflectional symmetries of the given figure of the letter 'F'.

Symmetry is an axis around which the object looks similar and faces opposite to each other. therefore, the line of symmetry acts as a mirror for the object.

As we can see that the given figure is the image of the letter 'F', and the letter 'F' is not symmetric about any of the axis as shown below.

Hence, there are no reflectional symmetries of the given figure of the letter 'F'.

The order of 250 boxes has the highest expected profit for Donaldson Game Co. based on the given data and calculations using Excel-only formulas.

To calculate the expected profit for each alternative order amount, we need to simulate the sales using the normal distribution with the mean and standard deviation given for each price point. We can then calculate the profit for each scenario by subtracting the cost of each box from the revenue generated by the sales.

Using Excel-only formulas, we can create 1,000 replications of the sales simulation for each alternative order amount and calculate the expected profit for each scenario. Then, we can use a one-way data table to compare the expected profit for each order amount and determine that the order of 250 boxes has the highest expected profit.

Therefore, based on the given data and calculations using Excel-only formulas, the order of 250 boxes has the highest expected profit for Donaldson Game Co.

Telling the managers in each of the 5 departments to randomly select 10 people to take the survey.

An unprejudiced portion of a population is chosen in a simple random sampling. With this sampling technique, the possibility of selection bias is reduced because every person of the population has an exact equal probability of being chosen.

A simple random sample is a group of people chosen at random, all with the same probability, from a larger group of people in statistics. It involves a method of randomly choosing a sample.

Random sampling assures that the results of sample should be close to those that would have been found if the complete population had been measured. With the simplest random sample, each unit in the population has an equal probability of being chosen.

Therefore, Option B is correct.

c. 4.6

21 X .22= 4.6

Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.

The simplified value of the given expression 0 + (1/2)×(2. 219^2)*9. 81 is 24.143810005.

To simplify the expression, we can use the Order of Operations (PEMDAS): 1. Parentheses 2. Exponents 3. Multiplication 4. Division 5. Addition 6. Subtraction. Hence, to simplify the expression 0 + (1/2)×(2.219^2)*9.81, we need to follow the order of operations (PEMDAS).

1. The parentheses must be solved first: (2.219^2) = 4.924361

2. The exponents are solved next: there are none in this expression

3. The multiplication must be carried out next: 4.924361x9.81 = 48.30405741

4. The division is done next: (1/2)x48.30405741 = 24.143810005

5. The addition and subtraction are carried out last: 0 + 24.143810005 = 24.143810005

Therefore, the simplified expression is 24.143810005.

Step-by-step explanation:

The rule of inference being used here is Modus Tollens. Modus Tollens is a valid deductive argument form that states if a conditional statement "If P, then Q" is true and the consequent Q is false, then the antecedent P must also be false.

In the given scenario, the conditional statement is "If the guard dog doesn't know a person, then it barks."

The observation that the dog didn't bark (Q is false) leads to the conclusion that the dog must have known the person (the antecedent P is false).

Each guy-wire is approximately 315.08 feet long.

We can use trigonometry to find the length of the guy-wires. Let's call the length of each guy-wire "x".

First, we can use the tangent function to find the height of the triangle formed by the first guy-wire and the antenna:

tan(0.33) = height/x

Rearranging, we get:

height = x * tan(0.33)

Similarly, we can use the tangent function to find the height of the triangle formed by the second guy-wire and the antenna:

tan(0.38) = height/x

Again, rearranging, we get:

height = x * tan(0.38)

Since both of these triangles share the same height, we can set the two expressions for height equal to each other:

x * tan(0.33) = x * tan(0.38)

Dividing both sides by x gives:

tan(0.33) = tan(0.38)

This equation is not true for all values of alpha and beta, but we are given that it holds for this particular case. Using this equation, we can solve for x:

x = 160 / tan(0.33)

x ≈ 315.08 feet

Therefore, each guy-wire is approximately 315.08 feet long.

Answer:

81

Step-by-step explanation:

square root of 729= 9

9×9=81

Answer:

Step-by-step explanation:

Formula of Volume= \(a^{3}\) - a = side

Therefore since the volume is given you just need to find the side.

729=\(a^{3}\) = \(\sqrt[3]{729}\) = a

            = 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Area of a square= 9 x 9 = 81\(cm^{2}\)
