(a) In cylindrical coordinates, the point (-2, 2, 2) is represented as (r, θ, z) = (2√2, 3π/4, 2).
(b) In cylindrical coordinates, the point (-9, 9√3, 6) is represented as (r, θ, z) = (18, 5π/6, 6).
(c) The specific value of the integral ∫E x dV cannot be determined without the function x and the limits of integration.
(d) To find the volume of the solid enclosed by the cone z = √([tex]x^{2}[/tex] + [tex]y^{2}[/tex]) and the sphere [tex]x^{2}[/tex] + [tex]y^{2}[/tex] + [tex]z^{2}[/tex] = 8,
(a) To convert the point (-2, 2, 2) from rectangular to cylindrical coordinates, we use the formulas r = √([tex]x^{2}[/tex] + [tex]y^{2}[/tex]), θ = arctan(y/x), and z = z. Plugging in the given values, we get r = 2√2, θ = 3π/4, and z = 2.
(b) Similarly, for the point (-9, 9√3, 6), we use the same formulas to find r = 18, θ = 5π/6, and z = 6.
(c) The integral ∫E x dV represents the triple integral of the function x over the region E enclosed by the given planes and cylinders. The specific value of the integral depends on the limits of integration and the function x, which is not provided in the given information.
(d) To find the volume of the solid enclosed by the cone z = √([tex]x^{2}[/tex] + [tex]y^{2}[/tex]) and the sphere [tex]x^{2}[/tex] + [tex]y^{2}[/tex] + [tex]z^{2}[/tex] = 8, we can set up the limits of integration in cylindrical coordinates. The limits for r are 0 to the intersection point between the cone and the sphere.

You deposit $500 in an account that earns 6.5% annual interest compounded yearly. Write a function that represents the balance y (in dollars) after x years.
Answer:
f(x)=.65+y
Step-by-step explanation:
.
The function for compound interest is A = 500 ( 1.065 )ˣ
What is Compound Interest?Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
Given data ,
Let the compound interest amount be represented as A
Now , the interest rate r = 6.5 %
The number of times the interest is applied = yearly
The principal amount P = $ 500
n = 1 ( compounded yearly )
t = x ( number of years )
So, the function that represents the balance y (in dollars) after x years is:
y ( x ) = 500 ( 1 + 0.065/1 )ˣ
On simplifying , we get
y ( x ) = 500 ( 1.065 )ˣ
Hence , the function is A = 500 ( 1.065 )ˣ

3 times the length of a field increased by 4 times the width gives 24 units. Two times the length decreased by 3 times the width is -1 unit. Find the dimensions
Answer:
width = 3
length = 4
Step-by-step explanation:
Ok so you can form a system of equations where w is the width and l is the length:
3l + 4w = 24
2l - 3w = -1
you want to eliminate one of the variables and then solve, so you can first take the top equation and multiply both sides by 2:
6l + 8w = 48
next, multiply the second equation by 3:
6l - 9w = -3
now that both include 6l, you can subtract the two equations
6l + 8w = 48
- (6l - 9w = -3)
17w = 51
divide both sides by 17
w = 3
Plug w = 3 into the equation 3l + 4w = 24:
3l + 4 * 3 = 24
3l + 12 = 24
subtract 12 from both sides
3l = 12
divide both sides by 3
l = 4

Amount discounted: si
х
5
?
9514 1404 393
Answer:
$14
Step-by-step explanation:
Computing 40% can be done a couple of ways.
40% = 40/100 = 4/10 = 2/5
40% of 35 = (2/5)(35) = 2(35/5) = 2(7) = 14
__
40% = 4/10 = 2(2(1/10))
40% of 36 = 2(2(1/10)(35)) = 2(2(3.5)) = 2(7) = 14
The amount discounted is $14.
If you know that a denominator in your ratio table is 12 and one of
the other ratios is 1/3, what numerator should you apply to your
12 denominator to make that ratio have the same value?
Answer:
the numerator is 4
Step-by-step explanation:
1/3 = ?/12
How did the values of the denominator change from 3 in the fraction 1/3 to 12 in the fraction ?/12? 3 was multiplied by 4 to get 12.
Then, since 12 is 4 times 3, then the missing numerator must be 4 times 1.
1/3 = 4/12
Answer: the numerator is 4

Number line graph with open circle on 24 and shading to the right.
Number line graph with closed circle on 24 and shading to the right.
Number line graph with open circles on 0 and 24 and shading in between.
Number line graph with closed circles on 0 and 24 and shading in between.
Answer:
Number line graph with closed circle on 24 and shading to the right.
Step-by-step explanation:
First, the graph has to have a closed circle on only 24.
Since she has $61 and needs at least $85 to buy a skateboard, she needs to have at least $24 saved to buy one.
This means the last 2 answer choices are wrong, because there cannot be shading in between.
The first answer choice is also wrong because it puts a open circle, instead of a closed one, on 24.
So, the correct answer is Number line graph with closed circle on 24 and shading to the right.

What is the average rate of change over the interval 1≤x≤3?
Enter your answer as a number, like this: 42
Answer:
the answer is 3
Step-by-step explanation:
just guessed and got it right since it wasn't 1 or 2 because i tried searching up the answer and they were around 2 but rlly close to 3
The rate of change of y with respect to x is 3.
We have a graph of a Non - linear function.
We have to determine the average rate of change over the interval
1 ≤ x ≤ 3.
What do you understand by the Average rate of change of two quantities plotted along X and Y axis respectively?It indicates the rate of change of y with respect to x. Mathematically -
[tex]$r=\frac{dy}{dx}[/tex]
or
[tex]$r =\frac{y(2)-y(1)}{x(2) -x(1)}[/tex]
According to the question -
The coordinate points plotted area s follows -
X Y
1 -2
2 0
3 4
Now, the average rate of change →
[tex]$r =\frac{y(2)-y(1)}{x(2) -x(1)}[/tex]
[tex]$r =\frac{4-(-2)}{3-1}[/tex]
r = 3
Hence, the rate of change of y with respect to x is 3.
