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

(a) Calculate the proportion of Juniors that are (1) currently working, (2) not working but have
had a job, and (3) never had a job.
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 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 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

2+9x=3(4x+1)-1
Find each solution
Answer:
x = 0
Step-by-step explanation:
Given
2 + 9x = 3(4x + 1) - 1 ← distribute and simplify right side
2 + 9x = 12x + 3 - 1
2 + 9x = 12x + 2 ( subtract 9x from both sides )
2 = 3x + 2 ( subtract 2 from both sides )
0 = 3x ( divide both sides by 3 )
x = 0

Which statements describe characteristics of an AND inequality? (Select all that apply.)
A) Values in the solution set satisfy both inequalities.
B) It is the intersection of two solution sets.
C) Shading generally occurs to the right or the left of the named values.
D) It is the union of two solution sets.
Answer:
A) Values in the solution set satisfy both inequalities.
B) It is the intersection of two solution sets.

Take those sets. The intersection is what A and B share.
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
Answer:
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.

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.

Answer:
a = 4 b = 5
Step-by-step explanation:
8a + 12b = 92......eqn 1
6a - 4b = 4......eqn 2
multiply eqn 2 by 3
18a - 12b = 12.....eqn 2
add eqn 1 and 2 to eliminate b
26a = 104
a = 4
put a = 4 into eqn 2
18(4) - 12b = 12
72 - 12b = 12
72 - 12 = 12b
60 = 12b

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!
Hi please help me solve this the topic is on circle geometry, whoever answers will be marked as the brainiest.
=====================================================
Explanation:
Line PR is tangent to the circle at point T. Angle PTO is 90 degrees because of this.
Angle TON is 124 degrees. Triangle TON is isosceles (since we have two sides of the triangle TO and ON equal to the radius). Therefore angles OTN and ONT are equal base angles. Call these x for now
-------
Since 3 angles of any triangle always add to 180, we can say...
x+x+124 = 180
2x+124 = 180
2x = 180-124
2x = 56
x = 28
Therefore,
angle PTN = (angle PTO) + (angle OTN)
angle PTN = 90 + 28
angle PTN = 118

In buffalo, New York the temperature was -12F in the morning. What will the temperature be if it drops 9F
Answer:
The correct answer is -21 degrees.
Step-by-step explanation:
We know that the original temperature was -12 degrees. If the temperature drops another 9 degrees, this means that it is getting colder or the temperature is getting lower; this lets us know that we should subtract 9 from the original temperature. This is modeled below:
-12 - 9
Now, we simply have to perform the subtraction to get:
-21 degrees
