The capacitance of the other cylinders are 2174. 94cm³ and 1208. 30cm³.
How to find the capacitanceCapacity of a cylinder is seen as its volume
Volume of a cylinder = πr²h
The heights of the cylinders are
a. 3cm
b. 9cm
c. 5cm
Let's find the radius
Capacity = 3. 142 × r² × 3
725 = 3. 142 × r² × 3
r² = [tex]\frac{725}{3. 142 * 3}[/tex]
r² = [tex]\frac{725}{9. 426}[/tex]
r² = 76. 91
r = √76. 91
r = 8. 77cm
Radius of the cylinders = 8. 77cm
For cylinder with height of 9cm
Capacitance = πr²h
Capacitance = 3. 142 × 8. 77 × 8. 77 × 9
Capacitance = 2174. 94 cm³
For cylinder with height of 5cm
Capacitance = 3. 142 × 8. 77 × 8. 77 × 5
Capacitance = 1208. 30 cm³
Thus, the capacitance of the other cylinders are 2174. 94cm³ and 1208. 30cm³.

The number f of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 80-20x. The number f of miles a submarine is from its destination x hours after leaving port is shown in the graph below. State the distance and length of time if each voyage. The ship traveled ___ miles in __ hours. The submarine traveled __ miles in __ hours.
The ship traveled 80 miles in 4 hours while the submarine traveled 75 miles in 5 hours.
How to determine the distance and time traveled?Based on the information provided, we can logically deduce that the ship is initially 80 miles away from its destination. Thus, f(x) would be equal to 0, if it traveled 80 miles and 0 miles away from its destination:
f(x) = 80 - 20x
0 = 80 - 20x
20x = 80
x = 80/20
x = 4 hours.
By critically observing the graph (see attachment) for the submarine's voyage, we can logically deduce the following:

A principal amount of $3000 is invested for 3 years at 4% compounded semi-annually. Use the compound interest formula to determine how much interest was earned on the investment.
The $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
Here,
P = $3000
r = 4% = 0.04
n = 2
t = 3 years
After plugging all the values in the formula:
[tex]\rm A = 3000(1+\dfrac{0.04}{2})^{2\times 3}[/tex]
After solving:
A = $3,378.49
I = A - P = 3,378.49 - 3000 = $378.49
Thus, the $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.

It depends if you mean

i.e. the sine part is getting squared, or
[tex]f(x) = \sin(x^2+2x-1)^2 = \sin\left((x^2+2x-1)^2\right)[/tex]
i.e. the argument to sine is getting squared. I'll assume the first case, since it's fairly common convention to write [tex]g(x)^2 = \bigg(g(x)\bigg)^2[/tex].
Now if

• by the power and chain rules we have
[tex]f'(x) = 2 \sin(x^2 + 2x - 1) \left(\sin(x^2+2x-1)\right)'[/tex]

Answer:
4x + 3y = 12
Step-by-step explanation:
Answer:
4x + 3y = 12
Step-by-step explanation:
At x-intercept, y = 0.
∴ When we substitute y = 0 into the equation, x should equal 3.
• 1st equation: 3x + 4(0) = 12 ⇒ x = 4 ❌
• 2nd equation: 4x + 3(0) = 7 ⇒ x = 7/4 ❌
• 3rd equation: 3x + 4(0) = 7 ⇒ x = 7/3 ❌
• 4th equation: 4x + 3(0) = 12 ⇒ x = 3 ✅
This means the 4th option is the correct one.
To check, we can replace x = 0 into the 4th equation to see if the y-intercept value comes out to be 4:
4(0) + 3y = 12 ⇒ y = 4 ✅

Use the given graph to determine the limit, if it exists. (4 points)
A coordinate graph is shown with an upward sloped line crossing the y axis at the origin that ends at the open point 3, 1, a closed point at 3, 7, and a horizontal line starting at the open point 3, 3.
Find limit as x approaches three from the right of f of x. .
Explanation:
Refer to the graph below. It should be similar to what your teacher gave you, based off the description.
Since we're approaching 3 from the right side, this means we'll be working with the horizontal line portion. We could start at something like x = 3.2 and move closer to 3 by getting to x = 3.1 then x = 3.01 then x = 3.001 and so on. We never actually get to 3 itself.
As x gets closer to 3 from this direction, the y values are approaching 3 since every point on this horizontal line has the same y coordinate. Technically the y value is already at 3, but it's the same idea.
In terms of notation, we can write [tex]\displaystyle \lim_{x\to3^{+}}f(x) = 3[/tex]
The portion [tex]x \to 3^{+}[/tex] means we're approaching 3 from the positive side, aka the right hand side on the number line.
When you are determining the probability of an event, why must the probablilty be between 0 and 1? explain your answer.
Probability is the ratio of the desired outcomes to all possible outcomes.
If there are no desired outcomes, the ratio is 0 over all possible outcomes, thus 0.
If the event is all possible outcomes, the ratio is all possible outcomes over all possible outcomes, thus 1.
Probability can never be below zero or negative because desired outcomes can never be negative. If an event is impossible that means there are no desired outcomes meaning that probability is zero, thus couldn't fall below
Probability can never exceed 1 as desired outcomes can never be greater than total outcomes.

The requried pilot can make at least one round trip before having to refuel. Hence, the correct answer is: A) 1
To determine how many round trips the pilot can make before having to refuel, we need to consider both the fuel capacity and the flight time limit.
Given:
Maximum fuel capacity = 5,300 gallons
Flight time limit before refueling = 400 minutes
Fuel required for one-way flight = 2,000 gallons
Flight time for one-way flight = 190 minutes
First, let's calculate the maximum number of one-way trips the pilot can make based on the fuel capacity:
Max one-way trips based on fuel capacity = Maximum fuel capacity / Fuel required for one-way trip
Max one-way trips = 5,300 gallons / 2,000 gallons = 2.65 trips
Since we cannot have a fraction of a trip, we need to consider the flight time limit.
The total flight time for a round trip is twice the one-way flight time: 2 * 190 minutes = 380 minutes.
The pilot can fly a round trip as long as the flight time for the round trip is within the flight time limit. In this case, the round-trip flight time of 380 minutes is less than the flight time limit of 400 minutes.
Therefore, the pilot can make at least one round trip before having to refuel. Hence, the correct answer is: A) 1

A linear function f(x) is given with two points, (2,3) and (0,4) lying on the line representing f(x).
It is asked to determine the slope of the line and state if the function is increasing or decreasing. of the value of the slope obtained.
Step 1 of 1
Determine the slope of the line.
The points as given in the question are (2,3) and (0,4). Now, the formula for the slope is given as
[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]
So, substitute [tex]$4 \& 3$[/tex] for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex] respectively, and [tex]$0 \& 2$[/tex] for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula.
