Answer:
32
Step-by-step explanation:
f(x)= 3(x-2)² + 5
Let x = -1
f(-1)= 3(-1-2)² + 5
Parentheses first
f(-1) = 3(-3)^2 +5
Exponents
f(-1)= 3*9 + 5
Multiply
f(-1) = 27+5
Add
f(-1) = 32
Hello,
To solve this equation, you first take the square root of both sides.
This will give you two options, because the square root of 64 could be 8 or -8.
Your equations are:
x + 3 = 8 or x + 3 = -8
Solving these equations give the solutions: x = 5 or x = -11
Option A is correct.
You can verify that it is correct by inputting the solutions and evaluating the expression.
I hope this helps, good luck!

Answer:
B
Step-by-step explanation:
In the right triangle with hypotenuse of 10 use the sine ratio to find x
sin20° = 
= 
Multiply both sides by 10
10 × sin20° = x, hence
x ≈ 3.4 ( to the nearest tenth ) → B
