A model rocket is launched 25 feet from you. When the rocket is at height h, the
distance d between you and the rocket is given by d = √216 +h2 where h and d
are measured in feet. What is the rocket's height when the distance between you and
the rocket is 100 feet? Round to 3 decimal places
Question 6
5 pts
The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
How to determine the rock's height?The function is given as:
d = √216 +h²
At a distance of 100 feet, it means that:
d = 100
So, we have:
√216 +h² = 100
Take the square of both sides
216 +h² = 10000
Subtract 216 from both sides
h²= 9784
Take the square root of both sides
h = 98.9
Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet

The bearing of point B from point A is 043°. Find the bearing of point A from point B.
The bearing of point A from point B is 223°.
We have given that,
The bearing of point B from point A is 043°.
We have to determine the bearing angle,
Suppose that we have the angle BAD=43 degrees.
So angle CBA=43 degrees.
What is the angle of bearing?
A bearing is an angle in degrees measured clockwise from north. Bearings are usually given as a three-figure bearing.
For example, 30° clockwise from the north is usually written as 030°.
Angle EBA= 180+∠CBA
=180°+43°
=223°
Therefore the bearing of point A from point B is 223°.

Find the value of x so the line that passes through the pair of points has the given slope.
(x, 4) (-3, 8), m = undefined
Answer:
x = - 3
Step-by-step explanation:
using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (x, 4 ) and (x₂, y₂ ) = (- 3, 8 )
m = [tex]\frac{8-4}{-3-x}[/tex]
since m is undefined, then the denominator must be zero, since division by zero is undefined , then equating the denominator to zero
- 3 - x = 0 ( add 3 to both sides )
- x = 3 ( multiply both sides by - 1 )
x = - 3

Keesha buys grapes and bananas. These bills and coins represent the cost of each item. How much did Keesha spend in all? Enter your answer in the box.
The total amount of money spent by Keesha to buy grapes and bananas is equal to $6.38.
How much did Keesha spend in all?
Based on the value of the bills and coins which represent the cost of each item, we would determine the total amount of money spent by Keesha to buy grapes and bananas.
For the grapes, we have:
Cost of grapes = 5 + (1 × 0.25) + (2 × 0.1) + 0.05
Cost of grapes = 5 + 0.25 + 0.2 + 0.05
Cost of grapes = $5.5.
For the bananas, we have:
Cost of bananas = (3 × 0.25) + 0.1 + (3 × 0.01)
Cost of bananas = 0.75 + 0.1 + 0.03
Cost of bananas = $0.88.
Total cost = 5.5 + 0.88
Total cost = $6.38.

The correct answer is option A. Which is the solution of the given equation will be (15,15).
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given equations are solved as:-
a - 1.2b = -3 or a = -3 + 1.2b
0.2a + 0.6b = 12
Put the value of a from equation 1 to the equation second.
0.2 ( -3 + 1.2 b) + 0.6b = 12
-0.6 + 0.24b + 0.6b = 12
0.84b = 12 + 0.6
0.84 b = 12.06
b = 15
Put the value of b in the first equation to find the value of a.
a = 1.2b - 3
a = (1.2 x 15) - 3
a = 15
Therefore the correct answer is option A. Which is the solution of the given equation will be (15,15).

Step-by-step explanation:
A bicycle company is designing women's bicycle frames. The frames can accommodate any woman taller than 54.5 inches. Given that the heights of adult American women are normally distributed, with a mean of 65 inches and a standard deviation of 3.5 inches, what percentage of American women CANNOT use the bicycles designed by this company
Using the normal distribution, it is found that 0.13% of American women CAN NOT use the bicycles designed by this company.
What is Normal Probability Distribution?The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
[tex]z=\dfrac{x-\mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean.Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 65\ \ \sigma= 3.5[/tex]
The proportion of women that cannot use the bikes(smaller than 54.5 inches) is the p-value of Z when X = 54.5, hence:
[tex]z=\dfrac{x-\mu}{\sigma}[/tex]
[tex]z = \dfrac{54.5-65}{3.5}[/tex]
Z = -3
Z = -3 has a p-value of 0.0013.
0.0013 = 0.13% of American women CAN NOT use the bicycles designed by this company.

what is the slope of the line graphed
Answer: undefined
Step-by-step explanation:
The slope of a vertical line is undefined because there is no rise/run and the slope formula would give you something over 0, which is undefined
Answer:
undefined
Step-by-step explanation:
the slope of the line graphed (a vertical line) is undefined.
No matter how large we set out slope, we will never reach a vertical slope. As we approach infinity, we will get closer, and closer, but we can never fully have a slope of a vertical line.
A slope of 1 means that we move up 1, over 1. A slope of 2 means that we move up 2, over 1. Even if we move up 5000, we still move over at least slightly (with a slope).
It is undefined because it does not run horizontally.
