The surface area is the sum of area of all faces of the shape

For the first shape:
four areas of four triangles + area of the square base

A= 4 (0.5*16*17) + (16*16) = 800 in^2

For the second shape:
area of the lateral cone + area of the circle base
A = 3.14*3* (9+64)^0.5  + 3.14 * 9 = 108.75 in^2

Hope that helps

What is this function written in vertex form? f(x) = (x –1)2 – 7 f(x) = (x 1)2 – 7 f(x) = (x –1)2 – 5 f(x) = (x 1)2 – 5
Maslowich

The vertex form of all expressions is given below.

We have given that the expressions

We have to write the function in vertex form.

<h3>What is the vertex form of the equation?</h3>

The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Therefore the first equation

f(x)=(x-1)^2-7

it can be written as

f(x)=1(x-1)^2+(-7)

The second equation can be written as

f(x) = (x+1)^2 -7

vertex for is,

f(x)=1(x-(-1))^2+(-7)

The third equation is,

f(x) = (x -1)^2 - 5

Vertex form is,

f(x)=1(x-1)^2+(-5)

Forth equation is,

f(x) = (x +1)^2 +(- 5)

Vertex form is,

f(x) =1 (x -(-1))^2 +(- 5)

Brainliest for correct answer! :)
professor190 [17]

Answer:

Mode: 44 (mode is biggest number)

Mean: 30 (the average between numbers)

Step-by-step explanation:

Calculating the Mean

44 + 43 = 87

25 + 8 = 33

87 + 33 = 120

120 + 30 = 150

150/5 = 30

The diagonal of a rectangle is 25 inch. the width is 15 in. what is the area of the rectangle?
givi [52]
D= diagonal= 25 in
w= 15 in

A= w√(d^2﹣w^2)

A= (15)√(25^2 - 15^2)
square in parentheses

A= (15)√(625 - 225)
subtract in parentheses

A= (15)√(400)
take square root of 400

A= (15)(20)

A= 300 in^2


ANSWER: The area is 300 inches squared

Hope this helps! :)
