Answer:

The calculation that will give us the estimated volume is the area of the base of the pyramid of Giza in square meters multiplied by the height of the pyramid of Giza in meters divided by 3 i.e A * h/3

Step-by-step explanation:

Here in this question, we are interested in giving the calculation that will give us the estimated volume of the Great pyramid of Giza in cubic meters.

Mathematically, from the first part of the question, the formula for this is obtainable.

We are told that the formula for calculating the volume of a pyramid is A times h/3 where A represents the area of the base of the pyramid and h represents the height of the pyramid.

In equation form;

V = A * h/3

From the question, we are told that the area of the base is 53,000 m^2 while the height is 150 m

Now, plugging these values into the equation above, we have

V = 53,000 * 150/3

V = 53,000 * 50 = 2,650,000 m^3

The estimated volume of the Great Pyramid of Giza in cubic meters is 2,650,000.

Given the following data:

To calculate the estimated volume of the Great Pyramid of Giza in cubic meters:

Mathematically, the volume of a pyramid is given by the formula:

[tex]Volume = \frac{1}{3} \times base \;area \times height[/tex]

Substituting the given parameters into the formula, we have;

[tex]Volume = \frac{1}{3} \times 53000 \times 150\\\\Volume = 17,666.667 \times 150\\\\Volume = 2,650,000[/tex]

Volume of the Great Pyramid of Giza = 2,650,000 cubic meters

Clear question is;

A ball is dropped from the top of a

building. The expression 4.9x² gives the distance in meters the ball

has fallen after x seconds. Write and simplify an expression that gives the

distance in meters the ball has fallen after x² seconds. after x³ seconds.

Answer:

A) Distance = 4.9x⁴

B) Distance = 4.9x^(6)

Step-by-step explanation:

We are given the expression 4.9x² which is the distance in meters the ball

has fallen after x seconds.

Thus,

A) after x² seconds, we have;

Distance = 4.9(x²)²

Distance = 4.9 * (x²) * (x²)

When we have to multiply 2 same numbers with the same power, the powers add up. Thus, we now have;

Distance = 4.9x⁴

B) after x³ seconds, we have;

Distance = 4.9(x³)²

Distance = 4.9 * (x³) * (x³)

When we have to multiply 2 same numbers with the same power, the powers add up. Thus, we now have;

Distance = 4.9x^(6)

Answer:

10% discounted

Step-by-step explanation:

500× X = 450

while X is the sale price

so we solve for X

(500X)÷500 = 450 ÷ 500

X = 0.9

then we turn that into percentage

0.9 × 100 = 90%

finding the discount percentage

100% - 90% = 10%

Answer:

[tex]\bold{y=2.5x^2+7x+3.3}[/tex]

Step-by-step explanation:

Given:

Parabola with

x − intercepts (−2.2, 0) and (−0.6, 0)

and

y − intercept (0,3.3)

To find:

Equation of parabola ?

Solution:

We can use factored form to find the equation of the parabola.

[tex]y=a(x-\alpha)(x-\beta)[/tex]

Where [tex]\alpha, \beta[/tex] are the x intercepts.

Let use put

[tex]\alpha = -2.2\\\beta = -0.6[/tex]

[tex]y=a(x-(-2.2))(x-(-0.6))\\\Rightarrow y =a(x+2.2)(x+0.6)[/tex]

Now, let us put y − intercept (0,3.3) in the above equation to find the value of a.

[tex]\Rightarrow 3.3 =a(0+2.2)(0+0.6)\\\Rightarrow 33 =a(22)(0.6)\\\Rightarrow 3 = 2a\times 0.6\\\Rightarrow a = 2.5[/tex]

So, the equation becomes:

[tex]\Rightarrow y =2.5(x+2.2)(x+0.6)\\\Rightarrow \bold{y=2.5x^2+7x+3.3}[/tex]

Answer:

y = 15, 11, and -1 when x = -1, 0, and 3 (respectively).  Together, we have the points (-1, 15), (0, 11), and (3, -1).

Step-by-step explanation:

Assuming you want to find the values of y for each evaluated x, we will simply plug in the values into the equation.

y + 4x = 11

y = 11 - 4x

For x = -1

y = 11 - 4(-1)

y = 15

For x = 0

y = 11 - 4(0)

y = 11

For x = 3

y = 11 - 4(3)

y = -1

Thus, we have the points, (-1, 15), (0, 11), and (3, -1).

Answer:  see proof below

Step-by-step explanation:

Use the formula for factoring a cubic:   (a³ + b³) = (a + b)(a² - ab + b²)

and the formula for a perfect square:    a² + 2ab + b² = (a + b)²

and the Pythagorean Identity:               cos²x + sin²x = 1

Proof LHS →  RHS

Given:                     sin⁶x + cos⁶x       + 3sin²x cos²x

Regroup:            (sin²x)³ + (cos²x)³     + 3sin²x cos²x

Factor Cubic:     (sin²x + cos²x)(sin⁴x - sin²x cos²x +  cos⁴x)   + 3sin²x cos²x

Pythagorean Identity:             1(sin⁴x - sin²x cos²x +  cos⁴x)   + 3sin²x cos²x

Add like terms:                         sin⁴x + 2sin²x cos²x +  cos⁴x

Regroup:                               (sin²x)² + 2sin²x cos²x +  (cos²x)²

Factor Perfect Square:                      (sin²x + cos²x)²

Pythagorean Identity:                                 (1)²

Simplify:                                                        1

Rational numbers you can solve. They have a solution.

Answer: Option A & D are true statements.

Work:

For option A, it states 1 pound = 2.75. Now when we divide 16.50 by 6 we get 2.75, so option A is true.

Option B states 2.75 pounds = 1$. We already know this isn't true seeing as 2.75 pounds would equal 7.56, so option B is false.

Option C reads as 5 pounds equal 15.50. When we multiply 5 by 2.75, we get 13.75, so option C is also untrue.

Option D quotes 12 pounds equals 33. When we multiply 12 by 2.75, it equals 33, so this is a true statement!

Option E says the point 3,9 is on the graph, but its not. So this is not true.

Answer:

q = 6/13, p = 35/13

Step-by-step explanation:

3p + 2q = 9

2p - 3q = 4

_________ (subtract the two equation from each other.)

p + 5q = 5

p = 5 - 5q

2(5 - 5q) - 3q = 4 (substitute value of p into equation)

10 - 10q - 3q = 4

10 - 13q = 4

-13q = -6

q = 6/13

3p + 2(6/13) = 9 (substitute value of q into equation)

3p + 12/13 = 9

3p = 105/13

p = 35/13

Answer:

At 7 seconds the instantaneous rate of change of the function s(t) with time which is the velocity is -11.18 m/s

Step-by-step explanation:

The given information on the height can be written as follows;

s(t) = -2.72·t² + 26.9·t + 6

Where;

s = The height (displacement) of the golf ball

t = The time taken during the motion of the golf ball

The velocity is found by finding the derivative of the displacement s as follows;

v = d(s(t))/dt = d(-2.72·t² + 26.9·t + 6)/dt = 2×(-2.72)×t + 26.9

When t = 7, v = 2×(-2.72)×7 + 26.9 = -11.18 m/s

Therefore the ball is coming down with 11.18 m/s speed at 7 seconds.

Answer:

Option A

Step-by-step explanation:

The expression that completes the blank is A. 11  x  w * x 3 = 11  x 3  x  w.

The commutative property is a mathematical concept that states that the order in which we multiply the factors does not affect the product.

According to the commutative property, a mathematical principle, the product is unaffected by the order in which we multiply the integers.

According to the above, the example of a commutative property is:

11  x w x 3 = 11 x  3 x w

This expression is the one with the commutative property because it has the same factors on both sides of the equation in a different order and that does not affect the result.

Therefore, the correct answer is A.

This question is incomplete because you are missing the options, here are the options:

A. 11 x w x 3 = 11 x 3 x w

B. 11 x w x 3 = 11 x w x 3

C. (11 x w) x 3 = 11 x (w x 3)

D. 11 x (w x 3) = (11 x w) + (11 x 3)
