I know that the answer to this is all real numbers less than or equal to 5. My question is how do you solve this (without a calculator)? Given f(x) = -3x^2 +5, what is the range of the function I tried to use -b/2a but I probably did it wrong. Thanks

Answers

find inverse function
y = f(x) = -3x^2 + 5
write x in terms if y
x = sqrt(-(y-5)/3)
inverse function is
f-1(x) = sqrt(-(x-5)/3)

domain of inverse is the range of the function

from inverse, inside sqrt must greater than or equal to 0 so that x-5 <= 0 which is x <= 5

Can someone help me with 10 math questions (: A cone has a radius of 5 inches and a height of 18 inches.

What is the exact volume of the cone?

A.
150π in3

B.
300π in3

C.
450π in3

D.
540π in3

Answers

so volue of a cone=1/3 times (area of base[which is a circle]) times height

area of base=area of circle=pi time radius^2
area=pi times 5^2
area=pi times 25=25pi

1/3 times 25pi times 18
25pi times 18 times 1/3
25pi times 18/3
25pi times 6=150pi


the answer is 150π in^3 or 150π cubic inches or C

( to solve, aprox pi to 3.141592 an multiply 150 by 3.141592=471.239 in^3)

amena ate 1-2 of a sandwich amena said they ate the same amount Lavonne said amena ate more could lavonne be correct explain your thinking

Answers

Amena ate 1/2 of a sandwich, and said that her an Lavonne ate the same amount, but Lavonne argued that Amena ate more.

If Amena ate 1/2 of the sandwich, then there is only 1/2 of the sandwich left, as 1 - 1/2 = 1/2.  Therefore, Lavonne couldn't have eaten more of the sandwich than Amena, because there isn't enough of the sandwich left for that.

Lavonne is incorrect.

10n squared -26n +12

Answers

10n^2-26n+12
their gcf is 2
2(5n^2-13n+6)
2(5n-3)(n-2)
n=3/5 or n=2

Answer:

Simplifying

2n + 4 + 5n = -3n + 2

Reorder the terms:

4 + 2n + 5n = -3n + 2

Combine like terms: 2n + 5n = 7n

4 + 7n = -3n + 2

Reorder the terms:

4 + 7n = 2 + -3n

Solving

4 + 7n = 2 + -3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '3n' to each side of the equation.

4 + 7n + 3n = 2 + -3n + 3n

Combine like terms: 7n + 3n = 10n

4 + 10n = 2 + -3n + 3n

Combine like terms: -3n + 3n = 0

4 + 10n = 2 + 0

4 + 10n = 2

Add '-4' to each side of the equation.

4 + -4 + 10n = 2 + -4

Combine like terms: 4 + -4 = 0

0 + 10n = 2 + -4

10n = 2 + -4

Combine like terms: 2 + -4 = -2

10n = -2

Divide each side by '10'.

n = -0.2

Simplifying

n = -0.2
