first of all, you need to assume that this shape is like a cone. So cone has a height and you can find it by using Thales's theorem. so it would be
\( \frac{x}{x + 6} = \frac{4}{8} \)
x is 6. So the total height of the cone has founded.
To find the volume of this frustum we have to subtract the volume of the small cone(at the top of the frustum) which has 6 cm in height from the big cone with 12 cm in height.
big cone Volume: ⅓(8²π×12)
-
small cone Volume: ⅓(4²π × 6)

Paul is saving for a down payment to buy a house. The account earns 13% interest compound quarterly, and he wants to have $15,000 in 4 years. What must his principal be? Round your answer to the nearest cent. Do not round at any point in solving process; only round your answer. Please help ASAP!! Thank you so much!
Answers
Answer:
The principal must be = $8991.88
Step-by-step explanation:
Formula for compound interest is:
\(A = P(1 + \frac{r}{n})^{nt}\)
Where A is the amount after 't' years.
P is the principal amount
n is the number of times interest is compounded each year.
r is the rate of interest.
Here, we are given that:
Amount, A = $15000
Rate of interest = 13 % compounded quarterly i.e. 4 times every year
Number of times, interest is compounded each year, n = 4
Time, t = 4 years.
To find, Principal P = ?
Putting all the given values in the formula to find P.
\(15000 = P(1 + \frac{13}{400})^{4\times 4}\\\Rightarrow 15000 = P(1 + 0.0325)^{16}\\\Rightarrow 15000 = P(1.0325)^{16} \\\Rightarrow 15000 = P \times 1.66817253\\\Rightarrow P = \dfrac{15000}{1.66817253}\\\Rightarrow P \approx \$8991.88\)
So, the principal must be = $8991.88
The principal required is $ 8993.
Using the formula;
A = P(1 + r/n)^nt
Where;
P = principal = ?
r = rate = 0.13
n = Number of times the interest is compounded = 4
t = time = 4years
Amount = $15,000
15,000 = P(1 + 0.13/4)^4(4)
15,000 = P(1.668)
P = 15,000/1.668
P =$ 8993

Answers
The BR is the perpendicular bisector of AC by CPCTC (corresponding parts of congruent triangles are congruent).
Based on the given information that angles ABR and ACR are right angles, and AB = AC, we can conclude that triangles ABR and ACR are right triangles.
Using the shared hypotenuse AR and the reflexive property, we can determine that side AB is congruent to side AC.
With this information, the transitive property allows us to conclude that angle BAR is congruent to angle CAR. Next, using the HL congruence postulate, we can prove that triangle ABR is congruent to triangle ACR.
This means that side BR is congruent to side CR, and angle BAC is bisected by line segment BR by the definition of bisector.

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

A company is tracking the number of hours of overtime paid each week. In the first 4 weeks, they find the following numbers of overtime hours: 20, 30, 45, and 67.5. Which is a possible explicit rule for overtime hours in the nth week?
Answers
The number of hours of overtime paid each week is an illustration of a geometric progression
The explicit rule is \(T_n = 20 * 1.5^{n-1}\)
How to determine the explicit ruleThe hours are given as:
20, 30, 45, and 67.5
The above function is a geometric function, and it is represented as:
\(T_n = ar^{n -1}\)
Where:
\(a = 20\) --- the first term
And we have:
\(r = \frac{30}{20}\)
\(r =1.5\)
So, we have:
\(T_n = 20 * 1.5^{n-1}\)
Hence, the explicit rule is \(T_n = 20 * 1.5^{n-1}\)

Eliminate the parameter in the equations x = t^1/3 and y = t – 4. How can the rectangular equation be described?
Answers
This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.
Elimination of the parameter means to rewrite the equations in terms of only x and y. To do this, substitute t from one equation into the other equation. Here, the two equations are:x = t1/3 and y = t – 4Substitute t from the first equation into the second equation:y = (x^3) – 4Now the equation is in terms of x and y only.
This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.The rectangular equation, y = (x^3) – 4 can be plotted on a graph. It is a cubic equation. The graph will look like a curve that passes through the point (0, -4) and continues to move towards infinity. The graph will be symmetric to the origin because the equation involves an odd power of x.
If the equation involved an even power of x, the graph would be symmetric to the y-axis. The graph will never touch the x-axis or y-axis, it will only approach them.In conclusion, the rectangular equation y = (x^3) – 4 is derived from the two parameter equations, x = t1/3 and y = t – 4. The graph of this equation is a cubic curve that is symmetric to the origin. The curve passes through (0, -4) and approaches the x and y-axes but never touches them.

Arranging the given set of numbers in ascending order: {4, 5, 8, 11}
Since the set has an even number of values, the median is the average of the two middle numbers. In this case, the two middle numbers are 5 and 8. To find the average, we add these two numbers and divide by 2:
