The figure shows two semicircles. Find the area of the shaded part in terms of pi. Please explain in detail thank you!
Answer: 3pi/2
This is equivalent to 1.5pi
The units for the area are in square centimeters.
===============================================
Work Shown:
The larger semicircle has radius 2 cm.
So r = 2 is plugged into the area of a semicircle formula below
A = (pi*r^2)/2
A = (pi*2^2)/2
A = (4pi)/2
A = 2pi
The area of the larger semicircle is 2pi square cm.
Repeat those steps but now use r = 1. This will compute the area of the unshaded smaller semicircle
A = (pi*r^2)/2
A = (pi*1^2)/2
A = pi/2
The area of the smaller unshaded semicircle is pi/2 square cm.
------------------------
From here, we subtract the two results to get the shaded area:
(larger semicircle area) - (smaller semicircle area) = (2pi) - (pi/2) = 3pi/2
This is equivalent to 1.5pi since 3/2 = 1.5

The graph of y = StartRoot x EndRoot is transformed as shown in the graph below. Which equation represents the transformed function?
On a coordinate plane, a curve opens up and to the right. It starts at (0, 2) and then decreases through (4, 0) into quadrant 4.
y = negative StartRoot x EndRoot
y = StartRoot (negative x) EndRoot + 2
y = StartRoot (negative x) EndRoot minus 2
y = negative StartRoot x EndRoot minus 2
Answer:
answer a did the test edg 2021
Step-by-step explanation:
Using translation concepts, it is found that the equation that represents the transformed function is:
[tex]y = -\sqrt{x-4} + 2[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the original graph is:
[tex]y = \sqrt{x}[/tex]
It moves up, while the new graph moves down, hence:
[tex]y = -\sqrt{x}[/tex]
It starts at (0,0), while the new graph starts at (0,2), hence:
[tex]y = -\sqrt{x} + 2[/tex]
It also goes through (4,0), that is, it was shifted 4 units to the right, hence:
[tex]y = -\sqrt{x+4} + 2[/tex]

What is the average rate of change of the function over the interval x = 0 to x = 6? f(x) = (2x - 1) / (3x + 5)
Answer:
The average rate of change of the function over the interval x = 0 to x = 6 is [tex]\frac{34}{195}[/tex].
Step-by-step explanation:
Geometrically speaking, the average rate of change ([tex]r[/tex]) of the function over a given interval is determined by equation of secant line, that is:
[tex]r = \frac{f(b)-f(a)}{b-a}[/tex] (1)
Where:
[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds.
[tex]f(a)[/tex], [tex]f(b)[/tex] - Function evaluated at lower and upper bounds.
If we know that [tex]f(x) = \frac{2\cdot x -1 }{3\cdot x + 5}[/tex], [tex]a = 0[/tex] and [tex]b = 6[/tex], then the average rate of change of the function over the interval is:
[tex]f(a) = \frac{2\cdot (0)-1}{3\cdot (0) +5}[/tex]
[tex]f(a) = -\frac{1}{5}[/tex]
[tex]f(b) = \frac{2\cdot (6)-1}{3\cdot (6)+5}[/tex]
[tex]f(b) = \frac{11}{13}[/tex]
[tex]r = \frac{\frac{11}{13}-\left(-\frac{1}{5} \right) }{6-0}[/tex]
[tex]r = \frac{34}{195}[/tex]
The average rate of change of the function over the interval x = 0 to x = 6 is [tex]\frac{34}{195}[/tex].

What are the zeros of f(x) = x^2 + x - 20?
Answer:
{-5, 4}
Step-by-step explanation:
Start by factoring f(x) = x^2 + x - 20. Since 4*5 = 20, we suspect that the factors are (x + 5) and (x - 4).
Next, set these factors equal to zero separately and solve each resulting equation for x. We get:
{-5, 4}

I have 3 troubling questions,
1. What is T when -9(T-2)=4(T-5)
2. what is X when 2(4x+2)=4x
3. what is S when 26-4s=9s
1. -9(T-2)=4(T-5)
Distribute
-9t+18=4t-5
Sub 4 because t is a like term and it is positive so sign changes because it is in opposite sides.
-14t+18=-5
Sub 18 to like term which is -5
-14t=-23
Divide
T= -14/-23 or -0.4375
2. 2(4x+2)=4x
Distribute
8x+4= 4x

Mason used a 30% coupon to buy a new computer. After the discount, the cost of the computer was $728.
Determine the original price of the computer. Show your work.
Answer:
The original price of computer is $ 1040
Solution:
Given that, Mason used a 30% coupon to buy a new computer
After the discount, the cost of the computer was $728
To find: original price of computer
From given question,
price after discount = $ 728
discount = 30 % of original price
Let "x" be the original price of computer
price after discount = original price - discount price

1 = 5k
k = 1/5
Test:
y = 15
x = k * y
x = 1/5 * 15; x = 3

B.)
x = 2; y = 6
2 α 6
2 = 6k
k = 2/6
k = 1/3
Test:
y = 15
x = k * y
x = 1/3 * 15; x = 5
Prin urmare; (b) este proporțională
C.)
x = 2; y = 6
7 α 3,5
7 = 3,5k
k = 7 / 3,5
k = 2
Test:
y = 5
x = 2 * 3.5
x = 7
Prin urmare; (c) nu este proporțională
x = 0,5; y = 1
0,5 α 1
0,5 = k
Test:
y = 4
x = k * y
x = 0,5 * 4; x = 2
Prin urmare; (d) este proporțională
x = 0,2; y = 2
0,2 α 2
0,2 = 2k
k = 0,2 / 2
k = 0,1
Test:
y = 4,5
x = 0,1 * 4,5
x = 0,45
Prin urmare; (e) nu este proporțională
x = 1; y = 12
1 α 12
1 = 12k
k = 1/12
Test:
y = 84
x = 1/12 * 84
