F(-1) f(x) = -3x2 + 2x - 7

egoroff_w [7]

Answer:

$f(-1) = -12$

Step-by-step explanation:

<u>Step 1: Set x to -1 and solve</u>

<u /> $f(x) = -3x^2+2x-7$

$f(-1) = -3(-1)^2+2(-1) - 7$

$f(-1) = -3(1) - 2 - 7$

$f(-1) = -3 - 2 - 7$

$f(-1) = -12$

Answer: $f(-1) = -12$

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2

vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

$Perimeter = 2(a+b)$

where a is height and b is base

Putting values:

$Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5$

So, Base of parallelogram b = 24.5 cm
