Answer:
A = 28.3
Step-by-step explanation:
R = d/2
R = 6/2
R = 3
A = πr^[2]
A = (3.14) x (3^[2])
A = 3.14 x 9
A = 28.26
Rounded to the nearest tenth is 28.3
<u>Solution for question 5:</u>
f(x) = 4x - 8
To find f^-1(x) write it as an equation:
y = 4x - 8
Then take x to left and y to right;
x = 4y - 8
Then solve for y;
y = (x + 8)/4 = x/4 + 2
Your y is the inverse of f(x) = 4x - 8
f^-1(x) = x/4 + 2
Answer:
The answer is H 3
Step-by-step explanation:
Answer:
the answer to this is 1/2(5+b)
Using the Pythagorean theorem:
WY =√(5^2 + 12^2)
WY = √(25 +144)
WY = √169
WY = 13 mm
