Answer:

Vol = 769.7 cubic ft

Step-by-step explanation:

"radius" is the distance from the center of a circle to the circle. So let's assume your pool is a circular pool with radius = 7ft and height = 5ft. It's a cylinder.

Volume of a cylinder:

Vol =

Base area•height

= pi•r^2 • h

= pi(7)^2•5

= pi•49•5

= pi • 245

= 245pi

Now, 245pi cubic ft is a perfectly good answer. But your teacher/text/class, may be asking for a decimal approximation.

If you use calculator pi (that's a lot of decimals) you get

Vol ~= 769.69 (to the hundredths place)

Vol ~= 769.7(to the tenths place)

If you were told to use 3.14 for pi

then you get

Vol ~= 769.3 cubic ft

But if you were told to convert units to gallons or liters there are more calculations (message, i can edit in these)

c^2-2cd+d^2 = (c-d)^2

We can verify this with the following steps

(c-d)^2 = (c-d)(c-d)

(c-d)^2 = c(c-d) - d(c-d)

(c-d)^2 = c^2-cd-cd+d^2

(c-d)^2 = c^2-2cd+d^2

Answer:

f is increasing on the interval x < 0

f is increasing on the interval 0 < x < 1

Step-by-step explanation:

From inspection of the graph, the curve is increasing when x < 1 and the curve is decreasing when x > 1

Therefore, the following are true statements:

Answer:

M=3/2

Step-by-step explanation:

Convert to slope-intercept form.

subtract 3x from both sides:

3x-2y=10

-3x      -3x

the threes will cancel out leaving you with:

-2y=10-3x

then divide both sides by -2:

-2y=10-3x

-2y   -2

your twos will then cancel out leaving you with:

y=-5-3/2

your answer is then:

3/2

heres a formula you can go by:

y=mx+b. m is the slope and b is the y-intercept.

I hope this helps :)

sorry if it doesn’t.

Answer:

y ≥ 1, (meaning y can be greater than 1/infinite numbers or just 1)

x ≥ 2, (meaning x can be greater than 2/infinite numbers or just 2)

Answer:  y = -15x + 225

Step-by-step explanation:

slope-intercept form is y = mx + b

The 225 is the starting amount.

x is the number of days since the machine was loaded.

-15 is the amount subtracted on average per day. It is the slope, m

y is the number of sodas left in the machine

Answer:

what is this question...

Answer:

18 hours

Step-by-step explanation:

First you subtract 13 from 68. 55, if you divided 55 by 3, you would have 18 with a remainder of 1. so 18 hours.

Answer: x = 1/2

Step-by-step explanation: Set it equal to zero by subtracting 4x from both sides:

4x² - 4x + 1 = 0

Now, factor it:

(2x - 1)(2x - 1)

Set each one equal to zero, but since they’re the same, you only need to do it once:

2x - 1 = 0

Add 1 to both sides:

2x = 1

Divide both sides by 2:

x = 1/2

Hope this helps!

Answer:

x=1/2

Step-by-step explanation:

4x^2+1=4x

or,4x^2-4x+1=0

or,(2x)^2 - 2*2*x+(1)^2 =0

or,(2x-1)^2 =0

or,2x-1 =0

or,2x=1

Therefore, x=1/2

Answer:

n=78

Step-by-step explanation:

Step - b * y - s step explanations

2n + 1 = 157

2n = 157 - 1

2n = 156

n = 156/2

n = 78

Answer:

58° and 122°

Step-by-step explanation:

Let the 1st angle be 'a'.

2nd angle = 6 more than twice of a = 2a + 6.

Supplementary angles add upto 180°.

=> a + (2a + 6) = 180

=> a + 2a + 6 = 180

=> 3a + 6 = 180

=> 3a = 174

=> a= 174/3 = 58

Thus, angles are:

a = 58°.

2a + 6 = 2(58°) + 6 = 122°

200 in sq

Step-by-step explanation:

look at the image as 2 faces, each face is a 10 x 10 area

area is length * width so 10 x 10 is 100

we have 2 of these squares meaning that you have multiply the 100 by 2

this gives you the 200 in sq

The Equation of line is  y + 17= 1/4(x - 164).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

X= 164, -8, 4, 164

Y= -99, -60, -57, -17

Using slope

= ( -17 + 57 )/ ( 164 - 4)

=  40/ (160)

=  1/4

So, Slope- intercept form

y + 17 = /4 ( x- 164)

The total amount earned in 10 hours of work is $390.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, an independent contractor he charges a $140 fee plus $25 per hour for each contract with the city.

Here, y represents the total amount he changes for a project and x represents the number of hours worked on a project.

Now, y=140+25x

Amount earned for 10 hours of work is

y=140+25×10

= 140+250

= $390

Therefore, the total amount earned in 10 hours of work is $390.
