Answers
The rate of change for the relationship, given the data is -2.25 gallon/min
What is velocity?Velocity is simply defined as the rate of change of displacement with time. Mathematically, it can be expressed as:
Velocity = displacement / time
With the above idea in mind, we can obtain the rate of change for the given relationship. This is illustrated below:
How to determine the rate of change Column 1 i.e time (min) = 7, 8, 9, 10.Column 2 i.e Water (gallons) = 38.5, 36.25, 34, 31.75.Rate of change =?Rate = Change in gallon / change in time
Rate = (36.25 - 38.5) / (8 -7)
Rate = -2.25 / 1
Rate of change = -2.25 gallon/min

For his long distance phone service, Aldo pays a $7 monthly fee plus 7 cents per minute. Last month, aldo's long distance bill was 20.86. For how many minutes was aldo billed
Answers
Answer:
198
Step-by-step explanation:
Bill costs 20.86
monthly fee plus cost per minute = 20.86
7 + (20.86-7) = 20.86
7+13.86=20.86
7+1386cents = 20.86
Minutes Aldo was billed = 1386÷7=198
What is the solution set of the quadratic inequality x^2-5<0
Answers
Answer:
-√5 < x < √5 .
Step-by-step explanation:
x^2 - 5 < 0
Solving x^2 - 5 = 0
x = √5 and -√5
These are the critical points
The coefficient of x^2 is positive so the graph ( which is a parabola) opens up.
so the region when x^2 - 5 is < 0 is when x > -√5 and < √5

Answers
Answer:

Answers
TU = 2x
UB = 3x
TB = 20
2x+3x=20
Solve that equation, you should get:
5x=20
Then divide by 5 on each side to get x.
x = 4
Then you want to plug x into each equation!
TU = 2x, so 2 • 4 = 8.
TU = 8
UB = 3x, so 3 • 4 is 12.
UB = 12

Use a triple integral to find the volume of the given solid. The solid bounded by the parabolic cylinder y = x2 and the planes z = 0, z = 4, y = 16.
Answers
Answer:
The answer is "[tex]\bold{\frac{1024}{3}}[/tex]".
Step-by-step explanation:
[tex]= \int\limits^{4}_{-4} \int\limits^{4}_{0} \int\limits^{16}_{x^2} dy\ dx \ dz \\\\= 2 \int\limits^{4}_{0} \int\limits^{4}_{0} \int\limits^{16}_{x^2} dy\ dx \ dz \\\\ = 2 \int\limits^{4}_{0} \int\limits^{4}_{0} (16-x^2) dx \ dz \\\\= 2 \int\limits^{4}_{0} \int\limits^{4}_{0} 16x -\frac{x^3}{3} dx \ dz \\\\= 2 (16x -\frac{x^3}{3})^4_{0} \ dz \\\\= 2 (4) (16x -\frac{64}{3}) \\\\=8(\frac{2}{3} \times 64) \\\\=(\frac{16\times 64}{3} ) \\\\= \frac{1024}{3}[/tex]
The volume of the given solid is [tex]\frac{1024}{3}[/tex] cubic units.
In this question we must use the triple integral formula in rectangular coordinates to determine the volume of the solid ([tex]V[/tex]):
[tex]V = \iiint dy\,dx\,dz[/tex] (1)
The solid is constrained by the following intervals:
[tex]y \in [x^{2}, 16][/tex], [tex]x \in [-4, 4][/tex], [tex]z\in [0, 4][/tex]
Then, the triple integral is now described:
[tex]V = \int\limits_{0}^{4}\int\limits_{-4}^{4}\int\limits_{x^{2}}^{16} dy\,dx\,dz[/tex]
Now we proceed to integrate thrice to obtain the volume:
[tex]V = \int \limits_{0}^{4}\int \limits_{-4}^{4} (16-x^{2})\,dx\,dz[/tex]
[tex]V = \int\limits_{0}^{4} \left(16\cdot x - \frac{x^{3}}{3}\right)\left|\limits_{-4}^{4} dz[/tex]
[tex]V = \frac{256}{3} \int\limits_{0}^{4} dz = \frac{1024}{3}[/tex]
The volume of the given solid is [tex]\frac{1024}{3}[/tex] cubic units.

on the line. Write an equation of the line in
point-slope form.
Answers
Answer:
The answer is
[tex] \huge y + 1 = 15(x - 3) \\ [/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question we have the final answer as

Three partners started a business with a joint capital of rs 1200000 if they invested in the ratio of 2:5:3 , how much did each invest
Answers
Number of business partners who started a business = 3
The total money they invested = 1200000
The ratio in which they invested = 2 : 5 : 3
Total number of parts = 2 + 5 + 3 = 10
Each part = 1200000 ÷ 10
Each part = 120000
Number of parts invested by one of the partners = 2
Money they invested = 120000 × 2
Money they invested = 240000
Number of parts invested by another partner = 5
Money another partner invested = 120000 × 5
Money they invested = 600000
Number of parts invested by the third partner = 3
Money invested by the last partner = 120000 × 3
Money they invested = 360000
Therefore , each of the partners invested 240000 , 600000 and 360000 rupees respectively .
