Do the pythagorean theorem to find your answer.
Formula: a^2 + b^2 = c2
12 = b
15 = c
a^2 + 12^2 = 15^2
Simplify the equation
a^2 + 144 = 225
Subtract 144 on both sides.
a^2 = 81
Square root of 81 is 9.

Find the 88 term of the arithmetic sequence 4,-1,-6
Answers
Answer:
an = a1 + d(n - 1)
a88 = 4 + (-5)(88 - 1)
a88 = 4 + (-5)(87)
a88 = 4 - 435
a88 = -431
So, the 88th term of the arithmetic sequence is -431.

Answers
Answer:
$200.65
Step-by-step explanation:
If they bought it for 147 then marked it up 75% you would do
$147+75% = 257.25
THEN they mark down
257.25 - 22% = $200.255 which would be

The circumference of the inner circle is 270.04 miles. What is the area of the shaded region?
Answers
area of a circle = [tex]\pi r^{2}[/tex]
circumference =[tex]2\pi r[/tex]
Okay so the center of the circle is the same for both of the circles lets take that value as m so the radius of the inner circle is 54 - m
we have the circumference of the inner circle which is 270.04 we can find the value of m using that
[tex]270.04=2\pi (54-m)\\270.04= 339.2-6.28m \\6.28m = 339.2-270.04\\m= 11.02[/tex]
the radius of the inner circle is therefore 42.98
and the full circle has a radius off 65.02
area of shaded region = area of full circle - area of inner circle
area of shaded region = [tex]\pi (65.02)^{2} - \pi (42.98)^{2}[/tex]
area of shaded region = [tex]13281.39 - 5803.4[/tex]
area of shaded region = 7478 rounded off to the nearest whole number
Ryan's take-home pay is $2,500 each month. The amount for gas is $125. Calculate the percentage Ryan uses on gas from his take-home pay. please help!! O^O
Answers
Answer: 5%
Step-by-step explanation:
Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.
The percentage that Ryan uses on gas from his take-home pay will be:
= Amount used on gas / Take home pay × 100
= 125/2500 × 100
= 1/20 × 100
= 5%
He used 5% on gas.

Given function
h(x) = 2x - 1#15 Find the inverse of h(x)
Substitute x with y and h(x) with x and solve for y:
x = 2y - 12y = x + 1y = 1/2x + 1/2The inverse is:
h⁻¹(x) = 1/2x + 1/2#16 The graph with both lines is attached.
The x- and y-intercepts of both functions have reversed values.
#17 Table of the inverse function will contain same numbers with swapped domain and range.
Initial look is like this:
x | -3 | -2 | -1 | 0 | 1 | 2 | 3h⁻¹(x) | -1 | | 0 | | 1 | | 2The rest of the table is filled in by finding the values:
x | -3 | -2 | -1 | 0 | 1 | 2 | 3h⁻¹(x) | -1 | -0.5 | 0 | 0.5 | 1 | 1.5 | 2Graph the function y = 6 – 2x. Click the intercepts to show the coordinates.
Answers
Answer:
Step-by-step explanation:
Let's find and use the intercepts. They speed up graphing of lines.
y-intercept: In y = 6 – 2x, let x = 0. Then y = 6, and the y-intercept is (0, 6).
x-intercept: In y = 6 – 2x, let y = 0. Then 2x = 6, and x = 3. The x-intercept is therefore (3, 0).
Plot these two points and then draw a line through both.

Write an equation to model the relationship between the number of weeks, x, and the number of views, f(x).
Enter the correct answer in the box by replacing the values of a and b.
Answers
Answer:
a = 5120
b = 1.25
Step-by-step explanation:
Let the exponential function representing the given table is,
f(x) = [tex]a(b)^x[/tex]
Here, f(x) = Number of views
x = Number of weeks
We choose two points from the given table and satisfy the equation of the function.
Let the points are (0, 5120) and (1, 6400)
For a point (0, 5120),
f(0) = a(b)⁰ = 5120
a = 5120
Now for the second point (1, 6400),
6400 = 5120(b)¹
b = [tex]\frac{6400}{5120}[/tex]
b = 1.25
Therefore, a = 5120 and b = 1.25 are the values.
Answer:
f(x)=8(0.5)^x

Kelly is attending physical therapyCB after knee surgery he walked 9 1/4 miles over 3 days how many miles is the per day simplilfy the answer as a mixed number
Answers
Answer:
The miles per day are: 3 1/12.
Step-by-step explanation:
With the information provided, in order to find the miles per day you have to divide the number of miles he walked by 3 that is the number of days:
9 1/4÷3
In order to solve this, first you have to convert the mixed number to an improper fraction by multiplying the denominator for the whole number, add the numerator and this would be divided by the denominator:
(4*9)+1/4
36+1/4
37/4
Now, you divide this by 3:
37/4÷3
37/(4*3)
37/12
You can conver this fraction into a mixed number by dividing 37 by 12. 12 goes into 37 three times which would be the whole number. Then, three times 12 is 36 and the remainder is 1. So, 1 would be the numerator and the denominator stays th same which is 12. The mixed number is: 3 1/12.
According to this, the answer is that the miles per day are: 3 1/12.
5x + 7y = 25
5x - 2y = -65
solve using elimination
(step by step please)
Answers
5x+7y=25
5x-2y=-65
subtract both of the equations
5x-5x=0
7y--2y= 7y+2y=9y
25--65=25+65=90
0+9y=90
9y=90
divide both sides by 9 to get y by itself
9y/9=90/9
cross out 9 and 9 which becomes 1*1*y=y
90/9=10
y=10
find x by using the substitution method
5x+7y=25
5x+7(10)=25
5x+70=25
move +70 to the other side
sign changes from +70 to -70
5x+70-70=25-70
5x=-45
divide both sides by 5 to get x by itself
5x/5=-45/5
cross out 5 and 5 then becomes 1*1*x=x
-45/5=-9
x=-9
