What are the instructions or equations to use
Answer:
Step-by-step explanation:
First let's re-write the equation:
f(x) = 3x² - 5x + 4
If f(-2). then we can re-write the equation as:
f(-2) = 3(-2)² - 5(-2) + 4
We must solve for exponent first: (-2)² = 4
f(-2) = 3(4) - 5(-2) + 4
Then solve for multiplication:
f(-2) = 12 + 10 + 4
Finally addition:
f(-2) = 26
that means that in a function, if X = -2, then F is equal to 26
Please do not mind me I am just trying to answer questions so I can message
The answer is all real numbers because -2x-6=-2x-6
Answer:
≈ 77 cm²
Step-by-step explanation:
The area of the shaded portion is calculated as
area of outer sector - area of inner sector
= (πR² - π r²) × 
( R is the outer radius, r is the inner radius )
= (π × 14² - π × 7² ) × 
= (196π - 49π ) ÷ 6
= 147π ÷ 6
≈ 77 cm² ( nearest whole number )
