Step-by-step explanation:
A rectangular swimming pool has a volume of 1750 ft.³ water is being added to the pool at a rate of about 20 ft.³ per minute. use an equation in point slope form to determine about how long will it take to fill the pool completely if there were already 1125 gallons of water in the pool use the fact that one cubic foot of space holds about 7.5 gallons of water round the answer to the nearest integer if necessary
Answer:
You have a rectangular pool 15 X 30 X 5 feet
The floor of the pool is 15X30 = 450 ft2
Two sides are 5X15 = 2(75) = 150 ft2
Two sides are 5X30 = 2(150) = 300 ft2
Total area to be painted: 900 ft2
(900 ft2)/(250 ft2/gal) = 3.6 gallons
Since we can't purchase .6 gallons we
must purchase 4 gallons of paint
The volume of the pool is 15X30X5 = 2250 ft3
1 ft3 = 7.48 gallons
2250(7.48) = 16,830 gallons of water

Since the box represents a proportional relationship, the empty box would be = 22.
What is a proportional relationship between two variables?When proportional relationship exists between two variables, it means that a particular value would be times with one variable to give the next compared variable.
For example, using the figures given above;
8 pages of notes = 16hours
1 page = 16/8 = 2 hours
Therefore, each page should be times by two to give the number of hours.

-n +4Find: f(n) +g(n)
Answer:
-n^3 – 5n + 4
Step-by-step explanation:
f(n) = -n^3 – 4
g(n) = -n +4
f(n)+ g(n) = (-n^3 – 4n)+(-n +4)
= (-n^3 – 4n -n +4)

Answer:
the answer is b
Step-by-step explanation:
they should have the same slope so just looking at that you cancel out d. But since it says has a y-intercept of 1 then it would cancel out the other 2. d is perpendicular to it not parallel
Answer:
b. [tex]y=5x+1[/tex]
Step-by-step explanation:
Slope-intercept form:
[tex]y=mx+b[/tex]
m is the slopeb is the y-interceptx and y are the corresponding coordinate points (x,y)When two lines are parallel, their slopes are the same. Note the slope of the given equation:
[tex]y=5x+7\\\\m=5[/tex]
The slope is 5, so the slope for the parallel equation will also be 5:

The highest elevation in a small country occurs on a mountain 1232 meters above sea level, while the lowest elevation in the same country occurs at -27 meters (below sea level). What is the difference in elevation between the highest and lowest points?
Answer: 1259 meters
Step-by-step explanation:
Highest elevation = 1232 meters
Lowest elevation = -27 meters
The difference in elevation between the highest and lowest points will be:
= 1232 - (-27)
= 1232 + 27
= 1259 meters
Note that (-) × (-) = +

Question in picture solve
Answer:
x= 13.5
Step-by-step explanation:
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
Check:
f(x) = 2x + 9
f(13.5) = 2(13.5) + 9= 27 + 9 = 36

Given:
There are 4 quarts in a gallon.
She wants to convert 6 quarts to a gallon.
To find:
Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.
Solution:
We have,
[tex]4\text{ quarts}=1\text{ gallon}[/tex]
[tex]1\text{ quarts}=\dfrac{1}{4}\text{ gallon}[/tex]
[tex]6\text{ quarts}=\dfrac{6}{4}\text{ gallon}[/tex]
Here, 6 quarts is equal to [tex]\dfrac{6}{4}[/tex] gallon. It means we need to multiply 6 by 4 in [tex]4\text{ quarts}=1\text{ gallon}[/tex] to find the answer.

Step-by-step explanation:
Here is the complete question;
A brand of cereal had 1.21milligrams of iron per serving. Then they changed their recipe so they had 1.8mg of iron per serving. What was the percent increase in iron?
Given
Initial amount of iron in cereal per serving = 1.21mg
final amount of iron in cereal per serving =1.8mg
Required
Percentage increase in iron
Increment = 1.8mg - 1.21mg
Increment = 0.59mg
% increase in iron = increment/original amount * 100%
% increase in iron = 0.59/1.21 * 100
% increase in iron = 0.4876 * 100
% increase in iron = 48.76%
Hence the percent increase in iron is 48.76%

Write a quadratic equation with the given transformations from the parent function y = x2
4) Reflect over x-axis, shift to the left 5 units, shift up 7 units
5) Vertical stretch by a factor of 4, shift down 11 units
6) Vertical compression by a factor of, reflect over x-axis, shift to the right 2 units, shift up 3 units.
Answer:
4
Step-by-step explanation:
By Using the Transformations of the parabola
[tex]y = -(x+5)^2+7\\y=4x^{2} +7\\y = -(x-2)^2+3[/tex]
Vertical Translation move the graph vertically - up or down[tex]y = x^2+ k[/tex]
Horizontal Translation move the graph horizontally - left or right[tex]y = (x - h)^2[/tex]
Reflection in x-axis
flip the graph over the x-axis, (negates the y-values of the coordinates)[tex]y = -(x^2)[/tex]
Reflection in y-axis
flip the graph over the y-axis,(negates the x-values of the coordinates)[tex]y = (-x)^2[/tex]
Stretch or Compress Verticallystretches away from the x-axis or compresses toward the x-axis
[tex]y = a .x^2[/tex]
| a | > 1 is a stretch;
0 < | a | <1 is a compression
Stretch or Compress Horizontallystretches away from the y-axis or compresses toward the y-axis
[tex]y=\frac{1}{a} x^{2}[/tex]
| a | > 1 is a compression by factor of 1/a;
0 < | a | <1 is a stretch by factor of 1/a
Now, we have [tex]y=x^2[/tex]
4). Reflect over x-axis, shift to the left 5 units, shift up 7 units
[tex]y = -(x+5)^2+7[/tex]
5) Vertical stretch by a factor of 4, shift down 11 units
[tex]y=4 x^{2} +7[/tex]
6) Vertical compression by a factor of, reflect over x-axis, shift to the right 2 units, shift up 3 units.
[tex]y=-(x-2)^{2} +3[/tex]

The translation of the given question is
f (x) = - 8x− 4 what is the slope y and the position coefficient f (x) = (6x− 12): 3 what is the slope y and the position coefficient
Answer:
We need to determine slope and position coefficient which is the intercept.
f (x) = - 8x− 4 we know that f(x) is y
slope intercept form of the line
y = -8x -4
slope = -8
intercept = -4
similarly
f (x) = 6x− 12
y = 6x -12
slope =6
intercept = -12
