Use a net to find the surface Area of the square pyramid The height of the pyramid is 9 yes and the base sides are all 2.5 yrds and its a square as a base

Answers

Answer 1

Answer:

[tex]Area = 51.68yd^2[/tex]

Step-by-step explanation:

Given

[tex]h = 9yd[/tex] -- height

[tex]a = 2.5yd[/tex] --- base sides

Required

Determine the surface area

The net is not given. So, I will solve directly.

The surface area is calculated as:

[tex]Area = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2}[/tex]

So, we have:

[tex]Area = 2.5^2 + 2*2.5\sqrt{\frac{2.5^2}{4} + 9^2}[/tex]

[tex]Area = 6.25 + 5\sqrt{\frac{6.25}{4} + 81}[/tex]

[tex]Area = 6.25 + 5\sqrt{1.5625 + 81}[/tex]

[tex]Area = 6.25 + 5\sqrt{82.5625}[/tex]

[tex]Area = 6.25 + 5* 9.086[/tex]

[tex]Area = 51.68yd^2[/tex]

Divide 40 by 4 to get 10.

5y−2=10

Add 2 to both sides.

5y=10+2

Add 10 and 2 to get 12.

5y=12

-8 is a negative number, which means many operations don't work the same on it. Subtracting a positive number from a negative number will give you the same result as adding the two positive numbers (in this case, 8 + 9), though the answer will also be negative. Hope this helps!

Which two functions always Which two functions always share the domain (-∞, ∞) and range (-∞, ∞)?
linear
absolute value
quadratic
exponential
reciprocal
cubic
cube root
square root

Answers

Answer:

Linear.

Cubic.

Step-by-step explanation:

Two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.

What is domain?

" Domain is defined as the set of all input values in the given function."

What is range?

" Range is defined as the set of all output values in the given function."

According to the question,

For linear function we can put all the real numbers for the independent variable 'x' that is ( -∞ , ∞).

Domain of a linear function = ( -∞ , ∞).

Output values of the linear function is set of all real numbers (-∞,∞).

Range of a linear function = (-∞,∞).

For cubic function

Cubic function is an odd polynomial . One end extends to +∞ and other end to -∞.

Domain and range of cubic function (-∞,∞).

Hence, two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.

Answer:

4x^2 - 47x + 33

Step-by-step explanation:

1. To multiply binomials, we must apply the FOIL method, meaning:

F = Multiply first term in first parentheses by first term in second parenthesesO = Multiply outside term in first parentheses by outside term in second parenthesesI = Multiply inside term in first parentheses by inside term in parenthesesL = Multiply last term in first parentheses by last term in second parentheses

Y-k = m(x-h) solve for m

Answers

Answer:

Simplifying

y + -1k = m(x + -1h)

Reorder the terms:

-1k + y = m(x + -1h)

Reorder the terms:

-1k + y = m(-1h + x)

-1k + y = (-1h * m + x * m)

-1k + y = (-1hm + mx)

Solving

-1k + y = -1hm + mx

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '-1y' to each side of the equation.

-1k + y + -1y = -1hm + mx + -1y

Combine like terms: y + -1y = 0

-1k + 0 = -1hm + mx + -1y

-1k = -1hm + mx + -1y

Divide each side by '-1'.

k = hm + -1mx + y

Simplifying

k = hm + -1mx + y

At NO point should a function have multiple x values. This fails the Vertical Line Test if visualized on a graph.

For Part A, there are no duplicate x values, meaning this function is valid.

For Part B, there is a duplicate x value - (2,9) & (2,4). Because of this, immediately the function is invalid. There can not be any duplicate x values in a valid function, PERIOD. If graphed, it fails the vertical line test.

Your cousin gave you $7.41 to buy a present. This amount covered 3/4 of the total cost. How much did the present cost?

Answers

Answer:

The answer is $5.55

Step-by-step explanation:

7.41 * 3/4= 5.5575

The present cost will be $9.88.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The amount to give cousin = $7.41

This amount covered 3/4 of the total cost.

Now,

Let the present cost = x

So, We can formulate;

⇒ 3/4 of x = $7.41

Solve for x as;

⇒ 3/4 × x = $7.41

⇒ x = $7.41 × 4 / 3

⇒ x = $9.88

Thus, The present cost will be $9.88.
