7 0

Answer:

207π ft²

Step-by-step explanation:

Given in the question,

diameter of the base  = 18 ft

slant height= 14 ft

radius of the base = 18/2

                              = 9 ft

Formula to calculate the surface area

<h3>A = πrl+πr²</h3>

<em>here l = slant height</em>

<em>         r = radius of the base</em>

<em />

plug values in the formula

A = π(9)(14)+π9²

A = 207π ft²

Given the function ƒ(x) = 5x^2 − 9x + 18, find ƒ(3). A) ƒ(3) = 31 B) ƒ(3) = 36 C) ƒ(3) = 49 D) ƒ(3) = 85
kumpel [21]

Answer:

36

Step-by-step explanation:

ƒ(x) = 5x^2 − 9x + 18,

Let x=3

ƒ(3) = 5*3^2 − 9*3 + 18,

      =5*9 - 27+18

        45 - 27+18

I NEED ANSWER ASAP! I HAVE A LOT OF POINTS, I WILL GIVE 50 POINTS AND BRAINLIEST TO FIRST ANSWERRRRRR!
Mekhanik [1.2K]

Answer:

A) A = 1; B = 0; C = 20

Step-by-step explanation:

The standard form for a quadratic is

Ax^2 +Bx +C=0

We are given

1/4x^2 + 5 = 0

Rewriting

1/4x^2 +0x+ 5 = 0

A = 1/4  B=0 C=5

We can multiply each side by 4

4(1/4x^2 +0x+ 5) = 0*4

x^2 +0x+ 20 = 0

A = 1  B=0 C=20

13x = 7(.78)

13x = 5.46

x = 5.46/13

x = .42
