Step-by-step explanation:

Here we are given the volume of rectangular pyramid as 90 cubic feet as we are required to find the volume of rectangular prism.

For that we need to use the theorem which says that

the volume prism is always one third of the volume of the pyramid . Whether it is rectangular of triangular base. Hence in this case also the volume of the rectangular prism will be one third of the volume of the rectangular pyramid.

Volume of Rectangular prism = 1/3 x Volume of rectangular pyramid

Therefore the volume of the rectangular pyramid = 30 cubic feet

The expanded quadratic equation with real coefficients is y = x² + 14 · x + 45.

In this problem we need to determine the expanded quadratic equation with real coefficients such that one of its roots is - 7 + i 2. According with the quadratic formula, quadratic equations can have two conjugated complex roots, that is:

r₁ = α + β, r₂ = α - β

Then, the complete set of roots of the quadratic equation are r₁ = - 7 + i 2 and r₂ = - 7 - i 2. Then, the factor form of the polynomial is:

y = (x + 7 - i 2) · (x + 7 + i 2)

y = x · (x + 7 + i 2) + (7 - i 2) · (x + 7 + i 2)

y = x² + 7 · x + i 2 · x + (7 - i 2) · x + 7 · (7 - i 2) + i 2 · (7 - i 2)

y = x² + 7 · x + i 2 · x + 7 · x - i 2 · x + 49 - i 14 + i 14 - i² 4

y = x² + 14 · x + 45

Answer: y=1x+4

Step-by-step explanation: the b (y-intercept) is 4 and when you go up 1/1 (1) it crosses the lines

Answer:  The correct answer is y = 10x – 45

Step-by-step explanation:

When graphing a line with a slope of 10 from point (5,5), we find that the y-intercept (where the line crosses the y-axis) is -45

Use the slope-intercept form (y=mx+b), where m=slope (10) and b=the y-intercept (-45)

y = 10x - 45

Answer:

1077.19 ft

Explanation:

Using the depression angle, we get that one of the angles of the formed triangle is also 18° because they are alternate interior angles, so we get:

Now, we can relate the distance x, the angle of 18°, and the height of the tower using the trigonometric function tangent, so:

Now, solving for x, we get:

Using the calculator, we get that tan(18) = 0.325, so x is equal to:

We must find the zeros of the following function:

1) First, we plot a graph of the function:

From the graph, we see that the function crosses the x-axis at x = 3, so x = 3 is one of the zeros of the function.

2) Because x = 3 is a zero of the function, we can factorize the function in the following way:

To find the coefficients b and c, we compute the product of the parenthesis and then we compare the different terms:

To have the same expressions at both sides of the equality we must have:

For x less than or equal to zero, we would apply the function f(x) = (1/2)^x

For x greater than zero, we would apply the function f(x) = 2^x

This falls in the 1st function

when x = -1 (less than 0)

This falls in the 1st function

when x = 0 (equal to 0)

when x = 1 (greater than 0)

This falls in the 2nd function

when x = 2 (greater than 0)

THis falls in the 2nd function

The given relationship using the Pythagorean theorem holds true for a right-angled triangle.

We are given a mathematical relationship using the Pythagorean theorem. The Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relationship between the three sides of a right triangle in Euclidean geometry. The equation is given below.

a² + b² = c²

We need to describe the situation when this relationship holds true. The variables "a", "b", and "c" represent the sides of a triangle. The Pythagorean theorem is applicable to a right-angled triangle. It states that the sum of the squares of the base and the perpendicular is equal to the square of the hypotenuse.

Here a, b, and c denote the lengths of the base, the perpendicular, and the hypotenuse of the triangle, respectively.

The given system of equations is expressed as

-10x - 10y = 10

-2x - 5y = -19

The first step is to make the coefficients of one of the variables in each equation equal. To make the coefficient of x equal, we would multiply the first equation by 2 and the second equation by 10. It becomes

- 20x - 20y = 20 equation 3

- 20x - 50y = - 190 equation 4

We would eliminate x by subtracting equation 4 from equation 3. It becomes

- 20x - - 20x - 20y - - 50y = 20 - - 190

- 20x + 20x - 20y + 50y = 210

30y = 210

y = 210/30

y = 7

Substituting y = 7 into the second equation, it becomes

- 2x - 5 * 7 = - 19

- 2x - 35 = - 19

- 2x = - 19 + 35 = 16

x = 16/- 2

x = - 8

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

y = mx also represents direct proportionality. We can write [m] as -

m = y/x

OR

y₁/x₁ = y₂/x₂

We have a cafeteria serves lemonade that is made from a powdered drink mix. There is a proportional relationship between the number of scoops of powdered drink mix and the amount of water needed to make it. For every 2 scoops of mix, one-half gallon of water is needed, and for every 6 scoops of mix, one and one-half gallons of water are needed.

We can write the proportional relationship as -

y = kx

Now, from the given information, we can write -

2 scoops need 0.5 gallon of water

6 scoops need 1.5 gallon of water

So -

k = 2/0.5

k = 2/(1/2)

k = 2 x 2 = 4

Equations that represents the relationship can be written as -

y = 4x + c

Now, 2 scoops need 0.5 gallon of water.

2 = 4 x 1/2 + c

2 = 2 + c

c = 0

So, the equation will be y = 4x.

Graph of y = 4x is attached at the end.

For 10 scoops of water -

10 = 4x

x = 2.5 gallons of water is needed.

Therefore, all the answers to the given parts are mentioned above.
