Well it is really easy to answer this question. Firstly we can calculate the complete circles area which comes out to be pi*r^2 so it becomes 16 pi.
And now we can calculate the complete triangles area which comes out to be 1/2 * base * height so 1/2 * 8 * 4 = 16 cm^2.
Now we can subtract both of them and get our final shaded areas region. So 16 pi or 50.24 minus 16 = 34.2
Answer:
B
Step-by-step explanation:
x/-5 < 9
×-5 ×-5
x < -45
x is less than -45
so, it's diagram B
The values of the functions are:
1. y = f(-7) = 128
2. y = f(5) = 0.0313
<h3>How to Find the Value of a Function?</h3>
We can evaluate a function by substituting the given value into the equation of the function, then simplify.
Given the function, y = f(x) = (1/2) ^ x
1. Find the value of f(-7):
y = f(-7) = (1/2)^-7
y = f(-7) = 2^7
y = f(-7) = 128
2. 1. Find the value of f(5):
y = f(5) = (1/2)^5
y = f(5) = 0.0313
