As shadow is directly propotional to height, we can say that,
Height/Shadow =k, where k is a constant.
So, in case of electric pole,
1410=k→(1)
In case of tree,
HT15=k→(2), where HT is height of tree
So, from (1) and (2),
1410=HT15
HT=14∗1510=21m
So, height of tree is 21 meters.

Answer:
She is 90 feet above ground before she begins to descend.
She descends by a rate of 5 feet per second.
Step-by-step explanation:
She is 90 feet above ground before she begins to descend. You can see that by looking at the y value of the highest point of the line, which is just between 80 and 100, which is 90.
We can find the rate of her descending by finding the slope. Remember that the slope formula is (y1-y2)/(x1-x2)
We can find two points on the line and plug the x and y values in. Let's use the points (0, 90) and (16, 10).
We plug the values in:
(90-10)/(0-16)
(80)/-16
-5
The slope is negative, which makes sense, because Aretha is descending and not ascending.
So, she is descending by a rate of 5 feet per second.
I hope this helps you!

A totem pole that is 90 feet tall casts a shadow that is 45 feet long. At the same time, a 6 – foot tall man casts a shadow that is x feet long. Find the length of the shadow.
Answer:
x=90+45/6
x=135/6
x=22.5
The length of the shadow of the 6-foot tall man is 3 feets
Actual Length :
Length of pole = 90 feets Length of man = 6 feetsLength of shadow :
Pole shadow = 45 feets Shadow of man = xUsing the relation :
(Pole length/shadow) = (man's height / shadow) (90 / 45) = (6 / x) Cross multiply :90x = 270x = 270 / 90 x = 3Therefore, the shadow of the man is 3 feets long.

A logical operation is a particular symbol or term that joins two or more informational expressions. The correct option is B.
What is Logical operator?A logical operation is a particular symbol or term that joins two or more informational expressions. It is most commonly used to determine if a connection between two sentences is true or untrue.
Given that p ↔ q represents the statement "He is wearing a coat if and only if the temperature is below 30°F.” Therefore, event p is He is wearing a coat, while event q represents the temperature below 30°F.
Now, In p^q, '^' represents the 'and' operator. Therefore, p^q represents He is wearing a coat and the temperature is below 30°F.
Hence, the correct option is B.

Answer:
Juniors Currently Working: 14/51 = 0.27; Not Working but Have Had a Job: 22/51 = 0.43; Never Had a Job: 15/51 = 0.29.
Seniors Currently Working: 30/80 = 0.38; Not Working but Have Had a Job: 40/80 = 0.5; Never Had a Job: 10//80 = 0.13.
There is an association between employment status and grade level. Depending on whether the student is a senior or junior impact the likelihood of their employment status. For instance, more seniors are likely to be currently working than juniors.
A rectangular parking lot has a length that is 8 yards greater than the width. The area of the parking lot is 560 square yards. Find the length and the width.
Answer: length=28, width=20
Step-by-step explanation:
Let x=width, then length=x+8
x(x+8)=560
x²+8x=560
x²+8x-560=0
(x-20)(x+28)=0
x=20 or x=-28 (rej) since a width can't be negative
20+8=28

Consider the function f(x) = x^2 – 331. Chivonne claims a domain restriction x ≥ 0 produces the inverse function f–1(x) = √ x - 331 .
Which statement describes whether Chivonne is correct?
A) The expression for f–1(x) is correct, but the domain restriction is not.
B) The domain restriction is correct, but the expression for f–1(x) is not.
C) Both the expression for f–1(x) and the domain restriction are correct.
D) Neither the domain restriction nor the expression for f–1(x) is correct.
Answer:
The correct option is;
D) Neither the domain restriction nor the expression for f⁻¹(x) is correct
Step-by-step explanation:
The given function can be written as follows;
f(x) = x² - 331
The inverse of the function f(x), which is f⁻¹(x), can be found as follows;
Let f(x) = x² - 331 = y, we have;
f(x) + 331 = x²
x = √(f(x) + 331)
We replace x with f⁻¹(x) and f(x) with x, to get;
f⁻¹(x) = √(x + 331)
We note that the domain of the inverse function will include values from x ≥ -331, and the correct inverse function √(x + 331) ≠ √x - 331
Therefore, we have that neither the domain restriction nor the expression for f⁻¹(x) is correct.
Answer:
B) The domain restriction is correct, but the expression for f–1(x) is not.

Let me know if this helps :)
Answer: 14
Step-by-step explanation: It’s a good idea to get into the habit of
using parentheses when substituting numbers in for variables.
Since a = 9 and b = 4, 2a - b is 2(9) - (4).
Now think about your order of operations.
Multiplication comes before subtraction so first multiply 2(9) to get 18.
So we have (18) - (4) which is 14.

is the following a true statement? 4/8 < 5/16
Answer:
No, because 4/8*2= 8/16
And 8/16 is greater than 5/16
Answer:
The statement is false.
Step-by-step explanation:
The easiest way to answer this question is to make both fractions have the same common denominator. In this case, we should alter the first fraction to have a denominator of 16 so that it matches the second fraction. To do this, we should multiply both the numerator and the denominator of the fraction by 2 (this is the same as multiplying by 1, which does not change the value of the fraction). This is modeled below:
4/8 * 2/2 = 8/16
Now, we can plug this value back into our original statement.
8/16 < 5/16
From comparing the numerators, we know that 5 is NOT greater than 8, so the statement is false.
Hope this helps!
Inverse Function -5 + 5/2x
Answer:
y = (2/5)x + 2
Step-by-step explanation:
To find the inverse of a function, we simply exchange the variables x and y and solve for y.
For this function we will write it as such:
y = -5 + (5/2)x
So to find the inverse, we will swap the x and y and solve.
y = -5 + (5/2)x
x = -5 + (5/2)y
x + 5 = (5/2)y
(2/5) * (x + 5) = y
(2/5)x + (2/5)5 = y
(2/5)x + 2 = y
Thus the inverse of the function is:
y = (2/5)x + 2

Generate a plan and describe the steps needed to solve the equation. 34 = –(m + 3)
Answer:
m=−37
Step-by-step explanation:
34 = -3 + -1m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add 'm' to each side of the equation.
34 + m = -3 + -1m + m
Combine like terms: -1m + m = 0
34 + m = -3 + 0
34 + m = -3
Add '-34' to each side of the equation.
34 + -34 + m = -3 + -34
Combine like terms: 34 + -34 = 0
0 + m = -3 + -34
m = -3 + -34
Combine like terms: -3 + -34 = -37
m = -37

Sample Response:
The negative sign outside the parentheses represents –1. Distribute the –1 to everything inside the parenthesis. Use the addition property of equality first to add 3 to both sides. Then use the division property of equality to divide both sides by -1.

h(x) = 2^x
Solve the equation h^-1 (x) =0.5
Answer:
The answer is
[tex]\sqrt{2} \: \: or \: \: 1.414[/tex]Step-by-step explanation:
[tex]h(x) = {2}^{x} [/tex]To solve the equation we must first find h-¹(x)
To find h-¹(x) equate h(x) to y
That's
[tex]y = {2}^{x} [/tex]Next interchange the terms
x becomes y and y becomes x
That's
[tex] {2}^{y} = x[/tex]Make y the subject
Take logarithm to base 2 to both sides
That's
[tex] log_{2}( {2} )^{y} = log_{2}x \\ y log_{2}2 = log_{2}(x) [/tex]But
[tex] log_{2}(2) = 1[/tex][tex]y = log_{2}(x) [/tex]So we have
[tex] {h}^{ - 1} (x) = log_{2}(x) [/tex]Now we can solve the equation
We have
[tex] log_{2}(x) = 0.5[/tex]Convert the logarithm into exponential form using the fact that
[tex] log_{a}(x) = b \: \: \cong \: \: x = {a}^{b} [/tex]So we have
[tex]x = {2}^{0.5} [/tex]But
[tex] {2}^{0.5} = \sqrt{2} [/tex]So we have the final answer as
[tex] \sqrt{2} \: \: or \: \: 1.414[/tex]Hope this helps you
