What is the volume of the square pyramid? Round to the nearest tenth

Mathematics
2 answers:
uysha [10]3 years ago
8 0

Answer:

The correct option is 3.

Step-by-step explanation:

The volume of a square pyramid is

V=\frac{1}{3}(\text{Base area})h

V=\frac{1}{3}a^2h                  .... (1)

Where, a is th side of base and h is the height of pyramid.

From the given figure it is clear that the height of the pyramid is 10 cm and the  length of base is 12 cm.

Substitute a=12 and h=10 in equation (1), to find the volume of the square pyramid.

V=\frac{1}{3}\times (12)^2\times (10)

V=\frac{1}{3}\times (144)\times (10)

V=(48)\times (10)

V=480

The volume of pyramid is 480 cm³. Therefore the correct option is 3.

ANSWER

Volume = 480.0{cm}^{3}

EXPLANATION

The volume of the square pyramid is given by;

Volume =  \frac{1}{3}  {l}^{2} \times  h

Where l=12cm is the length of the square base and h=10cm is the height of the pyramid.

We substitute the values into the formula to get;

Volume =  \frac{1}{3}  \times  {12}^{2} \times  10 {cm}^{3}

This simplifies to,

Volume =  \frac{1}{3}  \times  {12} \times 12\times  10 {cm}^{3}

Volume = 4 \times 12\times  10 {cm}^{3}

Volume = 480.0{cm}^{3}

Third option is correct.

The length of a rectangle is four times the width. The perimeter of the rectangle is 45 inches. Write a system of
Yakvenalex [24]

Answer:

81 square inches.

Step-by-step explanation:

Draw a diagram to represent what you know.

You don't know the values of the lengths so represent them algebraically.

You know the perimeter is 45 inches and that the perimeter is calculated by the sum of all of the sides of a shape.

You can rearrange to find the value of a side you've denoted as some unknown variable.

The area is given by the product of the sides. Express this algebraically and then input the value you found.

Function question<br><br>read the graph then solve
viktelen [127]

Answer:

  1. g(5x) = 0
  2. x = -10

Step-by-step explanation:

Do what your instructions say: read the graph and solve.

1. In order to find x, you look for the point where g(x) is 4. That point is found where x = -2. (See the first attachment.)

Then 5x = 5·(-2) = -10. To answer the question, you need to find the value of g(-10). Look where the graph crosses the vertical line at x=-10. It is at y=0, so ...

... g(5x) = g(-10) = 0

2. You already found the answer to this when looking for the answer to the first question. g(x) = 0 when x = -10. (See the second attachment.)

Consider a polynomial p(x) with a degree of 9. What is the largest possible number of x-intercepts and the largest possible numb
tia_tia [17]

Answer:

The largest possible number of x intercept is 9 while the largest possible number of relative max/min is 8

Step-by-step explanation:

For any polynomial of degree n with distinct and real solutions, it can have at most n different x intercepts. This would imply it can have at most 9 distinct real solutions.

It can also have at most n-1 relative max/min in alternating order. This is best illustrated when such polynomial is sketched on a graph.

For example a quadratic expression is a polynomial of degree 2 and has at most 2 distinct solutions and 1 relative max/min.

In this question, for the polynomial, its degree (n) = 9

So it can have at most 9 x intercepts and at most 8 relative max/min.
