Answer:

184.8 because

Step-by-step explanation:

if you do the surface area of pyramid math then your answer will come up to 189.093 and your first answer is closest to that by tenths so that will be your answer 184.8

Answer: A. 184.8ft2

Step-by-step explanation:

The pyramid is made up of four sides that are rectangular, each side has a height of 12.4ft and base length of 6ft.

The base area is a square of 6ft by 6ft.

For the sides, area of a triangle is 1/2 x base x height

= 1/2 x 6 x 12.4 = 37.2m2

For the four triangles = 4 x 37.2 = 148.8m2

For the square base, area is 6 x 6 = 36m2

Total surface area = 148.8 + 36 = 184.8ft2

G(x) = x^2 + 2x + 6
g(x) = x^2 + 2x + 1 + 5
g(x) = (x+1)^2  + 5

so
f(x) = x^2 to g(x) = (x+1)^2  + 5
shifted to the left 1 unit and up 5 units

answer is A. left 1 unit and up 5 units

What ate the domain and range of f(x)(1/6)x+2?
never [62]

Answer:

Domain : all real numbers

Range: All numbers greater than 2

Step-by-step explanation:

The shark. (Haha, I'm sorry.)

There are no restrictions on the x. X can be any real number.

The range, however, does have restrictions. The range has to be a number greater than 0.

Why?

Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.

A desk drawer is shaped like a rectangular prism. The height of the drawer is 7 inches. The bottom of the drawer has an area of
Bas_tet [7]

Answer:

1470 inches cubed

Step-by-step explanation:

Vol=length × width × height

But ALSO,

length × width = Area,

So we find another Volume equation,

Vol = BaseArea × height

This is the information you are given in the question.

Vol = 210 × 7

Vol = 1470 inches cubed

Use two rectangles of equal width to estimate the area between the graph of f(x) = x + cos(πx) and the x-axis on the interval [2
MrRissso [65]
We find the base of the rectangles by taking the difference between the interval endpoints, and dividing by 2.
Base of rectangle = (6 - 2) / 2
= 2

The area of the first rectangle:

(4 - 2)f(4) = 2[4 + cos(4π)]


The area the second triangle:

(6 - 4)f(6) = 2[6 + cos(6π)]


Now just compute the two areas and combined them. That will give you the estimated under the curve.


To evaluate the midpoint of each rectangle, we take the midpoint of the base lengths of each rectangle. This midpoint is the x value. Then evaluate the function at that x value.


The midpoint of the first rectangle is x=3. Evaluate f(3).
The midpoint of the second rectangle is x=5. Evaluate f(5).
