Answer:

13 hours, 33 minutes, 20 seconds

Step-by-step explanation:

The swimming pool will hold 1.22 million cubic inches of water, and if it fills up at 1500 cubic inches per minute, it will take 813 minutes and 20 seconds to fill the pool, which means that in simplest form, that will be 13 hours, 33 minutes, and 20 seconds.

<em>Hopefully the answer and explanation helps!</em>

Answer:

Is y = 4x - 7 a linear function?
Is y = 6x² - 1 a linear function?
Is y = $\frac{1}{2x}$ + 10 a linear function?

Step-by-step explanation:

Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function.
No it's not - when you graph this equation, it results in a v- kinda shape on the graph. Linear functions are [straight] lines on a graph, and this line wasn't straight. In fact, this wasn't even a line.
No it's not - when you graph this equation, it results in a bend at the origin. The line on the graph is not straight, so this is not a linear equation.

For the graphs -

The first one represents the linear function [y = 4x - 7]

The second one (that looks like an L) represents the last not linear function [y = $\frac{1}{2x}$ + 10]

The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]

Answer:

110 feet

Step-by-step explanation:

The formula to find the area of a rectangular prism is A = 2 (wl + hl + hw)

Substitute the values:

A = 2 (5x5 + 3x5 + 3x5)

A = 2 (25 + 15 + 15)

A = 2 (55)

A = 110

Solve the equation for x, where x is a real number (5 points): <br> -2x^2 + 7x + 7 = 6

Artemon [7]

Start by doing a subtraction of 6 to both sides so that the equation becomes -2x^2 + 7x + 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                             x = [ -b ± √(b^2 - 4ac) ] / (2a)
                             x = [ -7 ± √((7)^2 - 4(-2)(1)) ] / ( 2(-2) )
                             x = [-7 ± √(49 - (-8) ) ] / ( -4 )
                             x = [-7 ± √(57) ] / ( -4)
                             x = [-7 ± sqrt(57) ] / ( -4 )
                             x = 7/4 ± -sqrt(57)/4
The answers are 7/4 + sqrt(57)/4 and 7/4 - sqrt(57)/4.
