G(n) = 2n^2 - 4n; Find g(-9)
rusak2 [61]

Answer:

g(n) = 2n^2 - 4n; Find g(-9)

The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.

P-Parentheses

E-Exponents

M-Multiplication

D-Division

A-Addition

S-Subtraction

Step-by-step explanation:

g(-9) = 2(-9)^2 - 4(-9)

g(-9) = 18^2 -4(-9)

g(-9) = 134+36

g(-9) = 170

I really hope this helps!

Sincerely,

The area of a rectangle is 4 2 square inches. The length is 7 inches. What is the perimeter of the rectangle?
77julia77 [94]

Answer: 26

Step-by-step explanation:

Area of a rectangle is length times width.

The area, 42, divided by the length, 7, is 6.

2 sides of the rectangle are 7, so the other 2 are 6.

6+6+7+7=26. The perimeter is 26.

Please help this is (finding the volume of a cone) any tips, answers anything ??
trasher [3.6K]

Answer:

Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi

Step-by-step explanation:

The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.
