Paul is filling a kiddy pool that can hold up to 25 gallons of water. The water hose fills the tub at a constant rate. When Paul checks the pool, it contains 5 gallons of water. Three minutes later, the pool contains 7.4 gallons of water. At what rate does the pool fill up with water?
Answer:
0.8 gallons per second
Step-by-step explanation:
Given that :
Filling occurs at a constant rate ;
Change in gallon of water in pool within a 3 seconds time interval ;
Assume :
At t = 0 ; gallons = 5
At t = 3 ; gallons = 7.4
Chanhe in gallons with time.;
(7.4 - 5) / (3 - 0)
2.4 / 3
= 0.8 gallons per second

Kyle starts saving for his first car by opening a savings account and depositing $100 . He plans to make a deposit every month to continue saving. The amount of money in Kyle's savings account can be modeled by the sequence 0=100, , =−1+75 , where is the number of months since his initial deposit. Is the sequence a function? Why or why not?
Answer:
The sequence is a function
Step-by-step explanation:
Given
Sequence: [tex]A_0=100[/tex]; [tex]A_n=A_{n-1}+75[/tex]
Required
Is the sequence a function
To determine if the sequence is a function or not, we start by calculating its range from the domain:
When n = 0; [tex]A_0=100[/tex]
When n = 1: [tex]A_1 = A_{1-1} + 75 = A_0 + 75 = 100 + 75 = 175[/tex]
When n = 2; [tex]A_2 = A_{2-1} + 75 = A_1 + 75 = 175 + 75 = 250[/tex]
When n = 3; [tex]A_3 = A_{3-1} + 75 = A_2 + 75 = 250 + 75 = 325[/tex]
This implies that:
The domain (n) and the range (An) can be represented as:
[tex]\left[\begin{array}{c}n&-&0&1&2&3\\-&-&-&\end{array}\right][/tex] [tex]\left[\begin{array}{c}A_n&-&100&175&250&325\\-&-&-&\end{array}\right][/tex]
The above shows that the sequence is a one to one relation and a one to one relation is always a function.
Answer:
Yes, because for each input value, n, there is only one possible output value.

(») 1. Write a compound inequality for the graph.
+

-2
6 help neededddd!!
Answer:
-2 < x ≤ 6
Step-by-step explanation:
This graph shows conjunction. This means that the two statements of the inequality bare true at the same time. Therefore, it follows that:
x > -2 ("we use greater than" because the empty/unshaded circle indicates that -2 is not included)
And
x ≤ 6 (we use greater than or equal to because the shaded circle indicates 6 is included)
Joining both statements together, we would have:
-2 < x ≤ 6
Describe how the graph of y= x2 can be transformed to the graph of the given equation. y = x2 + 9 Shift the graph of y = x2 left 9 units. Shift the graph of y = x2 right 9 units. Shift the graph of y = x2 down 9 units. Shift the graph of y = x2 up 9 units.
Answer:
Shift of graph of y=x^2 up 9 units.
Option D is correct option.
Step-by-step explanation:
We are given:
[tex]y = x^2[/tex]
We need to describe how the graph of [tex]y = x^2[/tex] can be transformed to the graph of the given equation [tex]y=x^2+9[/tex]
We know the transformation rule:
If f(x) is transformed into f(x)+h, the graph is transformed vertically up h units.
So, In our case:
[tex]y=x^2[/tex] is transformed into [tex]y=x^2+9[/tex]
So, The graph is transformed vertically up 9 units.
Or we can write, shift of graph of y=x^2 up 9 units.
Option D is correct option.

Identify the terms and like terms in the expression 8 - x2 + x - 4x.
Answer:
x
Step-by-step explanation:
all those terms can be devided by x
Answer:
The terms are 8, -2x, x, and -4x. Like terms are -2x, x, and -4x because they have the same variable raised to the same exponent.
Step-by-step explanation:
Consider the equation:
X2+ 2x – 15 = 0
A) First, use the "completing the square" process to write this equation in the form
(2 + D)2= E
Answer:
x² + 2x - 15 = 0
x² + 2x + 1 = 16
(x + 1)² = 16
You can then go forward with that to solve it:
x + 1 = √16
x = -1 ± √16
x = -1 ± 4
x = 3, -5

What is the y-coordinate?
Enter your numeric answer only.
Answer:
i have find the value of x and y in above figure hope it helps
The y-coordinate that represents the solution to the system of equations is 4
The equations are given as:
[tex]-x+y=1[/tex]
[tex]3x-y=5[/tex]
Make x, the subject in the first equation
[tex]-x+y=1[/tex]
[tex]x = y - 1[/tex]
Substitute y - 1 for x in the second equation
[tex]3x-y=5[/tex]
[tex]3(y - 1) - y = 5[/tex]
Open the brackets
[tex]3y - 3- y = 5[/tex]
Collect the like terms
[tex]3y - y = 5+3[/tex]
Evaluate the like terms
[tex]2y = 8[/tex]
Solve for y
[tex]y = 4[/tex]
Hence, the y-coordinate is 4

A supervisor records the repair cost for 22 randomly selected VCRs. A sample mean of $75.50 and standard deviation of $18.07 are subsequently computed. Determine the 99% confidence interval for the mean repair cost for the VCRs. Assume the population is approximately normal.
Answer:
The 99% confidence interval for the mean repair cost for the VCRs
(65.801, 85.199)
Step-by-step explanation:
Explanation:-
Mean of the sample(x⁻) = $75.50
Given the standard deviation of the sample (S) = $18.07
Given the size of the sample 'n' = 22
Degrees of freedom = n-1 =22-1 =21
critical value t₍₀.₀₁, ₂₁₎ = 2.5176
The 99% confidence interval for the mean repair cost for the VCRs
[tex](x^{-} - t_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +t_{0.01} \frac{S.D}{\sqrt{n} })[/tex]
[tex](75.50 - 2.5176 \frac{18.07}{\sqrt{22} } , 75.50 +2.5176 \frac{18.07}{\sqrt{22} })[/tex]

The largest species of jellyfish is the lion's mane jellyfish. One particular specimen has a diameter of 1.03 meters and tentacles that are 29 meters long. The specimen weighs 164 kilograms and can travel at a speed of 1.38 meters per second.
What is the diameter of the specimen in centimeters?
Answer:
The diameter of the specimen in centimeters is 103 cm.
Step-by-step explanation:
In order to determine the diameter in centimeters of the largest specimen of jellyfish, knowing that said diameter is 1.03 meters, and that 1 meter is equal to 100 centimeters, the following calculation must be performed:
1.03 x 100 = X
103 = X
Therefore, the diameter of the specimen in centimeters is 103 cm.
