Step-by-step explanation:
X = number of added ounces
Y = toppings added
Z = cost of smoothie bowl
$5 the cost of minimum bowl.

What is the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line represented by y=34x−8?
Answers
Answer:
The equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
\(y=-\frac{1}{34}x+\frac{91}{17}\)Step-by-step explanation:
We know the slope-intercept form of the line equation
\(y=mx+b\)
where m is the slope and b is the y-intercept
Given the line
\(y=34x-8\)
comparing with the slope-intercept form of the line equation
The slope m = 34
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 34
Thus, the slope of the the new perpendicular line = – 1/m = -1/34 = -1/34
Using the point-slope form
\(y-y_1=m\left(x-x_1\right)\)
where m is the slope of the line and (x₁, y₁) is the point
substituting the values of slope = -1/35 and the point (12, 5)
\(y-y_1=m\left(x-x_1\right)\)
\(y-5=-\frac{1}{34}\left(x-12\right)\)
Add 5 to both sides
\(y-5+5=-\frac{1}{34}\left(x-12\right)+5\)
\(y=-\frac{1}{34}x+\frac{91}{17}\)
Therefore, the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
\(y=-\frac{1}{34}x+\frac{91}{17}\)In ΔABC, m∠B = 90°, cos(C) =

In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse.
We are given that AB = 16 units, which is the side adjacent to angle C. Let's assume AC is the hypotenuse.
Using the cosine formula:
cos(C) = adjacent / hypotenuse
cos(C) = AB / AC

FILL IN THE BLANK. if it is impossible for events a and b to occur simultaneously, the events are said to be mutually exclusive. for such events, p(a or b) _________.
Answers
If it is impossible for events A and B to occur simultaneously, the events are said to be mutually exclusive. For such events, P(A or B) is equal to the sum of the individual probabilities of events A and B.
In other words, if A and B are mutually exclusive events, the probability of A or B occurring is equal to the sum of the probabilities of A and B individually.
Mathematically, P(A or B) = P(A) + P(B).
This holds true because when two events are mutually exclusive, the occurrence of one event excludes the possibility of the other event happening at the same time. Therefore, there is no overlap in the outcomes, and we can simply add their probabilities to calculate the probability of either event occurring.

Find a particular solution to the differential equation y′′ + 3y = -9
Answers
To find a particular solution to the given differential equation, we can assume a constant value for y and solve for it.
The given differential equation is y′′ + 3y = -9. To find a particular solution, we assume y = k, where k is a constant. Substituting this assumption into the differential equation, we get k'' + 3k = -9. Since k is a constant, its second derivative is zero, so the equation simplifies to 3k = -9. Solving for k, we find k = -3.
Therefore, a particular solution to the given differential equation is y = -3. This means that for this particular value of y, the second derivative of y is zero, and when we substitute it into the differential equation, it satisfies the equation.

Answers
Answer:
2250m
Step-by-step explanation:
Step 1
Since
Hence,
tan x = 3/4
tan y=5/7
tan x = BA/ CA where BA = height and CA = distance
3/4 = h/ d
4h = 3d
h = 3d/4.......... Equation 1
tan y = BA / DA + 150m
5/7 = h/d + 150
7 × h = 5(d + 150)
7h = 5d + 750............ Equation 2
Since h = 3d/4
7(3d/4) = 5d + 750
21d/4 = 5d + 750
Multiply both sides by 4
21d = 4(5d + 750)
21d = 20d + 3000
21d -20d = 3000
d = 3000
Distance (d) = 3000m
Substitute 3000m for d in equation 1
h = 3d/4
h = 3 × 3000/4
h = 2250m

\(tangent=\dfrac{opposite}{adjacent}\)
We have:
\(\tan x^o=\dfrac{3}{4}\\\\\tan y^o=\dfrac{5}{7}\)
By definition of tangent, we have:
\(\tan x^o=\dfrac{AB}{AC}\\\\\tan y^o=\dfrac{AB}{AC+150}\)
Therefore we have the system of equations:
\(\left\{\begin{array}{ccc}\dfrac{AB}{AC}=\dfrac{3}{4}&(1)\\\\\dfrac{AB}{AC+160}=\dfrac{5}{7}&(2)\end{array}\right\)
From (1)
\(\dfrac{AB}{AC}=\dfrac{3}{4}\) cross multiply
\(3AC=4AB\) divide both sides by 3
\(AC=\dfrac{4AB}{3}\)
Substitute it to (2):
\(\dfrac{AB}{\frac{4AB}{3}+150}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB}{3}+\frac{3\cdot150}{3}}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB}{3}+\frac{450}{3}}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB+450}{3}}=\dfrac{5}{7}\\\\AB\cdot\dfrac{3}{4AB+450}=\dfrac{5}{7}\)
\(\dfrac{3AB}{4AB+450}=\dfrac{5}{7}\) cross multiply
\((3AB)(7)=(5)(4AB+450)\\\\21AB=(5)(4AB)+(5)(450)\)
\(21AB=20AB+2250\) subtract 20AB from both sides
\(AB=2250\)

How long will it take any sum to double itself a. With a 14 percent simple interest rate? b. With a 14 percent interest rate, compounded annually? c. With a 14 percent interest rate, compounded continously?
Answers
a. Simple interest: around 14.29 years.
b. Annual compound interest: about 5 years.
c. Continuous compound interest: roughly 4.95 years.
a. With a 14 percent simple interest rate, the time it takes for a sum to double can be calculated using the formula:Time = (100 / interest rate) * 2
In this case, the interest rate is 14 percent, so the time it takes for the sum to double is:Time = (100 / 14) * 2 = 14.29 years (approximately).
b. With a 14 percent interest rate compounded annually, the time it takes for a sum to double can be calculated using the compound interest formula:Time = log(2) / log(1 + (interest rate / 100))
Substituting the values, the time it takes for the sum to double is:
Time = log(2) / log(1 + (14 / 100)) = 5.00 years (approximately).
c. With a 14 percent interest rate compounded continuously, the time it takes for a sum to double can be calculated using the formula:
Time = ln(2) / (interest rate / 100)
Using the values, the time it takes for the sum to double is:
Time = ln(2) / (14 / 100) = 4.95 years (approximately).

estimate the error that is made by approximating the sum of the given series by the series the fitst 5 terms 1/k^3
Answers
The error involved in approximating the sum of the given series by the sum of the first five terms of the series is `R5 = 1/6³ + 1/7³ + ...`.
To estimate the error that is made by approximating the sum of the given series by the series the first 5 terms 1/k³, we can use the remainder term of a convergent series.
The given series is ∑ 1/k³ from k = 1 to infinity.We have to find the error involved in approximating the sum of the given series by the sum of the first five terms of the series.
That is, we need to find the difference between the actual sum of the series and the sum of the first five terms of the series.
The sum of the series is given by: `S = 1/1³ + 1/2³ + 1/3³ + 1/4³ + ... + 1/n³ + ...` We can use the remainder term of the series to find the error in approximation.
The remainder term `Rn` is given by: `Rn = Sn - S` where `Sn` is the sum of the first `n` terms of the series. Thus, we have to find the remainder term for `n = 5`.
The remainder term `Rn` is given by: `Rn = S - Sn = 1/6³ + 1/7³ + ...` Since the given series is convergent, the remainder term `Rn` tends to zero as `n` tends to infinity.
So, if we take the sum of the first five terms of the series, the error involved in approximation is given by the remainder term `R5`.
The error involved in this approximation is very small and can be neglected.

When you listen to the sound of a bouncing ping-pong ball that has been dropped onto a cement floor, what mathematical pattern do you hear? Explain,
Answers
A drop of water is denser than a ping-pong ball.
Usually, water is made of particles that are firmly pressed together. In differentiation, plastic (the material ping pong balls are made of) may be a lightweight fabric and the particles are not as firmly stuffed together.
The thickness of a ping pong ball is 0.0840 g/cm³, though water’s thickness is 997 kg/m³. Subsequently, ping pong balls aren’t about as thick as water and will continuously coast and surface greatly quickly.
The ping pong ball appears to oppose gravity and coast within the air.
Ping-pong balls drift within the water since they are amazingly lightweight, empty, and filled with air. Too, the water’s surface pressure makes it simple for the ping pong ball to drift.
In expansion, water is denser than ping pong balls, making them look for the most noteworthy point of water.

what is the mass of a cubic meter of air at room temperature (20°c)?
Answers
The mass of a cubic meter of air at room temperature (20°C) depends on various factors such as atmospheric pressure and humidity. However, as a rough estimate, at standard atmospheric conditions, the mass of dry air in a cubic meter is approximately 1.2 kilograms.
What is cubic meter?
A cubic meter is a unit of volume in the metric system. It represents the amount of space occupied by a cube that measures one meter on each side. It is commonly used to measure the volume of solids, liquids, or gases.
The mass of air can be calculated by considering its density. At standard atmospheric pressure (101.325 kilopascals) and temperature (20°C), the approximate density of dry air is about 1.2 kilograms per cubic meter. This value may vary depending on factors such as altitude, humidity, and temperature deviations from the standard conditions.
It's worth noting that including water vapor in the air would increase the mass further. Therefore, the given estimate of 1.2 kilograms represents the mass of dry air, neglecting the presence of water vapor.

Answer two questions about Equations A and B: A. 5x-2+x=x-4 B. 5x+x=x-4 How can we get Equation B from Equation A?
Answers
Answer:
The answer is below
Step-by-step explanation:
To be able to get equation B from equation A, we have to compare equation A with equation B. Given that equation A. is 5x-2+x=x-4 and equation B is 5x+x=x-4.
Equation B: 5x+x=x-4.
Equation A: 5x-2+x=x-4.
Simplifying equation A to be in the form of equation B:
5x -2 + x = x - 4
Adding 2 to both sides:
5x + x -2 + 2 = x - 4 + 2
5x + x = x - 4 + (+2)
= equation A + 2
But 5x+x=x-4 = equation A
Therefore Equation B is the same as Equation A + 2
