Axis of symmetry for f(x) = -2x2 + 20x -42
Ksenya-84 [330]
For the function f(x)=2x^2 +20x-42

We can use the formula for the axis of symetry, which is x= \frac{-b}{2a}

With the values substituted, we get...

\frac{-20}{2(-2)} =5

Therefore the axis of symmetry is x=5

Answer:

\huge\boxed{\sf h = 6.75 \ in.}

Step-by-step explanation:

<u>Given Data:</u>

Base area = A_{B} = 108 in.²

Volume = V  = 729 in.³

<u>Required:</u>

Height = h = ?

<u>Formula:</u>

V=A_{B}h

<u>Solution:</u>

For h, rearranging formula:

\displaystyle h = \frac{V}{A_{B}} \\\\h =\frac{729 \ in.^3}{108 \ in.^2} \\\\h = 6.75 \ in.\\\\\rule[225]{225}{2}

Mrac [35]

Answer:

see below

Step-by-step explanation:

1.  The inverse means take the not of both sides

If it is Saturday, then there is no school.

 Inverse     If it is not Saturday, then there is school.

The converse flips the then and the if

If there is no school, then it is Saturday.

2.) The first given part is the if, what will happen is the then part

If you are a freshman, then you are required to attend orientation.

3.)

Given: 3x+1=-14 Prove: x=-5

Statements    Reasons

1. 3x+1=-14     Given

2. 3x=-15          Subtraction Property of equality  ( since we subtract 1 from                         each side)

3. X=-5          Division Property  ( since we divide each side by 3)

Given f(x) = 3x - 1 and g(x)= -x + 6, find f(-2) + g(5).<br> A. -6<br> B. 6<br> C. 8
marta [7]

Answer:

A. -6

Step-by-step explanation:

f(x)=3x-1\\\\

In order to find f(-2) we will plugin x=-2

f(-2) = 3(-2)-1\\f(-2)=(3\times(-2))-1\\f(-2)=-6-1

f(-2)=-7

g(x)=-x+6

In order to find g(5) we will plugin x=5

g(5)=-5+6

g(5)=1

f(-2)+g(5)\\=-7+1\\=-6

∴ f(-2)+g(5)=-6
