A triangular pyramid has a base area of 24 square meters and a height of 4 meters. What is the volume of the pyramid?
Answer:
32 cubic meter
Step-by-step explanation:
Volume for any pyramid is given by following expression
volume of pyramid = 1/3( area of base of pyramid * height of pyramid)
________________________________
In the problem
base area of pyramid = 24 sq. m
height = 4 m
Therefore substituting the above given value in formula for volume of pyramid we have
volume of pyramid = 1/3( 24 sq. m * 4 m) = 8 sq. m * 4 m (since 24/3 = 8)
volume of pyramid = 32 cubic meter.

Jackie makes an $800 deposit into a bank account earning 4.5% interest.
a. If the interest is compounded quarterly how much money will Jackie have in 10 years?
b. If the interest is compounded continuously how much money will Jackie have in 10 years?
C. If Jackie's money is compounded continuously, how long will it take her money to double?
d. If Jackie's money is compounded monthly, how long will it take her money to triple?
For part a, Jackie will have approximately $1217.62 after 10 years with quarterly compounding interest. For part b, Jackie will have approximately $1226.96 after 10 years with continuous compounding interest. For part c, it will take approximately 15.43 years for Jackie's money to double with continuous compounding interest. For part d, it will take approximately 38.51 years for Jackie's money to triple with monthly compounding interest.
Explanation:For part a, to calculate the amount of money Jackie will have in 10 years with quarterly compounding interest, we can use the compound interest formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times compounded per year, and t is the number of years. Plugging in the values, we have A = 800(1 + 0.045/4)^(4*10), which gives us A ≈ $1217.62.
For part b, to calculate the amount of money Jackie will have in 10 years with continuous compounding interest, we can use the formula: A = P * e^(rt), where e is Euler's number and approximately equal to 2.71828. Plugging in the values, we have A = 800 * e^(0.045 * 10), which gives us A ≈ $1226.96.
For part c, to find out how long it will take Jackie's money to double with continuous compounding interest, we can use the formula: t = ln(2) / r, where t is the time in years and r is the interest rate. Plugging in the values, we have t = ln(2) / 0.045, which gives us t ≈ 15.43 years.
For part d, to find out how long it will take Jackie's money to triple with monthly compounding interest, we can use the formula: t = ln(3) / (n * ln(1 + r/n)), where t is the time in years, n is the number of times compounded per year, and r is the interest rate. Plugging in the values, we have t = ln(3) / (12 * ln(1 + 0.045/12)), which gives us t ≈ 38.51 years.
a. If the interest is compounded quarterly, Jackie will have approximately $1,313.63 in 10 years.
b. If the interest is compounded continuously, Jackie will have approximately $1,256.39 in 10 years.
c. If Jackie's money is compounded continuously, it will take approximately 15.4 years for her money to double.
d. If Jackie's money is compounded monthly, it will take approximately 62.47 years for her money to triple.
Step 1
To solve this problem, we can use the compound interest formula:
[tex]\[ A = P \left(1 + \frac{r}{n}\right)^{nt} \][/tex]
Where:
- A is the amount of money accumulated after t years, including interest.
- P is the principal amount (the initial deposit).
- r is the annual interest rate (as a decimal).
- n is the number of times interest is compounded per year.
- t is the time the money is invested for, in years.
Given:
- [tex]\( P = \$800 \)[/tex]
-[tex]\( r = 0.045 \)[/tex] (4.5% as a decimal)
- n is either 4 for quarterly compounding or tends to infinity for continuous compounding.
Step 2
We'll calculate each part step by step:
a. Quarterly compounding:
- [tex]\( n = 4 \)[/tex]
- [tex]\( t = 10 \)[/tex]
Substituting into the formula:
[tex]\[ A = 800 \left(1 + \frac{0.045}{4}\right)^{4 \times 10} \]\[ A = 800 \left(1 + \frac{0.045}{4}\right)^{40} \]\[ A = 800 \left(1 + 0.01125\right)^{40} \]\[ A = 800 \times 1.01125^{40} \]\[ A = 800 \times 1.642032881 \]\[ A = \$1,313.63 \][/tex]
Step 3
b. Continuous compounding:
For continuous compounding, we use the formula:
[tex]\[ A = P e^{rt} \][/tex]
Where e is the base of the natural logarithm, approximately equal to 2.71828.
Substituting the values:
[tex]\[ A = 800 \times e^{0.045 \times 10} \]\[ A = 800 \times e^{0.45} \]\[ A = 800 \times 1.570482165 \]\[ A = \$1,256.39 \][/tex]
Step 4
c. To find out how long it takes for the money to double with continuous compounding, we use the formula:
[tex]\[ A = P e^{rt} \][/tex]
We need to solve for t when [tex]\( A = 2P \):[/tex]
[tex]\[ 2P = P e^{0.045t} \]\[ 2 = e^{0.045t} \]\[ \ln(2) = 0.045t \]\[ t = \frac{\ln(2)}{0.045} \][/tex]
Substituting the values:
[tex]\[ t = \frac{\ln(2)}{0.045} \]\[ t = \frac{0.693}{0.045} \]\[ t = 15.4 \text{ years} \][/tex]
So, it takes approximately 15.4 years for Jackie's money to double with continuous compounding.
Step 5
d. To find out how long it takes for the money to triple with monthly compounding, we use the compound interest formula again, but this time we set [tex]\( A = 3P \)[/tex]:
[tex]\[ 3P = P \left(1 + \frac{0.045}{12}\right)^{12t} \]\[ 3 = \left(1 + \frac{0.045}{12}\right)^{12t} \]\[ \ln(3) = 12t \ln\left(1 + \frac{0.045}{12}\right) \]\[ t = \frac{\ln(3)}{12 \ln\left(1 + \frac{0.045}{12}\right)} \][/tex]
Substituting the values:
[tex]\[ t = \frac{\ln(3)}{12 \ln\left(1 + \frac{0.045}{12}\right)} \]\[ t = \frac{1.099}{12 \times 0.0037} \]\[ t = 62.47 \text{ years} \][/tex]
So, it takes approximately 62.47 years for Jackie's money to triple with monthly compounding.

The history test has 19 questions. There are
true or false questions worth 4 points each
and multiple-choice questions worth 6 points
each. How many multiple-choice questions
are on the 100 point test?
Answer:
12 multiple choice questions
Step-by-step explanation:
The system of equations is:
m + t = 19 (quantity of questions)
6m + 4t = 100 (point value)
We use elimination to solve.
Multiply everything in the first equation by 4.
4m + 4t = 76.
subtract that from the second equation.
2m = 24
Divide both sides by 2.
m = 12
Answer:
Step-by-step explanation:
Let x be the number of true or false questions.
Let y be the number of multiple choice questions
Total questions = 19
x + y = 19 ---------------(i)
Total points = 100
4x + 6y = 100 ---------------(ii)
Multiply equation (i) by (-4).
(i)*(-4) -4x - 4y = -76
(ii) 4x + 6y = 100 {Now add. thus x will get eliminated}
2y = 24
y = 24/2
y= 12
There were 12 multiple choice question
A circle has a radius of 6. An arc in this circle has a central angle of 330º.
What is the length of the arc?
Either enter an exact answer in terms of or use 3.14 for it and enter your answer as a decimal.
Answer:
The length of the arc is approximately [tex]\( 17.27 \)[/tex] units.
Explanation:
To find the length of the arc, we use the formula:
[tex]\[ \text{Arc Length} = \frac{\text{Central Angle}}{360^\circ} \times 2\pi r \][/tex]
where:
- Central Angle is the measure of the angle formed by the arc and the center of the circle
- [tex]\( r \)[/tex] is the radius of the circle
Given:
- Radius ([tex]\( r \)[/tex]) = 6
- Central Angle = 330º
Plugging the values into the formula:
[tex]\[ \text{Arc Length} = \frac{330^\circ}{360^\circ} \times 2\pi \times 6 \][/tex]
[tex]\[ \text{Arc Length} = \frac{330}{360} \times 2\pi \times 6 \][/tex]
[tex]\[ \text{Arc Length} = \frac{11}{12} \times 2\pi \times 6 \][/tex]
[tex]\[ \text{Arc Length} = \frac{11}{2} \pi \][/tex]
Using [tex]\( \pi \approx 3.14 \)[/tex], we can approximate the value:
[tex]\[ \text{Arc Length} \approx \frac{11}{2} \times 3.14 \][/tex]
[tex]\[ \text{Arc Length} \approx 17.27 \][/tex]
So, the length of the arc is approximately [tex]\( 17.27 \)[/tex] units.

All parbolas with vertical directrix open to the left or right
True or false
The statement is false because parabolas can also open upwards or downwards if the directrix is horizontal. A parabola's open direction depends on the position of the directrix relative to the focus.
Explanation:The statement that "All parabolas with vertical directrix open to the left or right" is false. A parabola's orientation is determined by the position of its directrix in relation to its focus. If you have a vertical directrix, the parabola will indeed open to the left or the right, depending on the side of the directrix the focus lies. However, if the directrix is horizontal, the parabola will open upwards or downwards. To help understand this, recall that the directrix serves as a line that, in combination with the focus, defines the set of points that make up the parabola—that is, points equidistant from both the focus and the directrix. Furthermore, the equation of a parabola can change based on the orientation and position of the axis, the focus, and the directrix, as shown in various figures and equations related to parabolic motion and geometry.

the slope?
1)O
2)3
3)5
4)7
In this situation, where the price of the soda remains constant regardless of the number of refills, the slope of the function representing this scenario is 0.
Explanation:In mathematics, the slope of a function can be thought of as the rate of change of the dependent variable (in this case, cost) in relation to the independent variable (in this case, number of refills). Given that the price for the soda remains constant at $3 regardless of the number of refills, the slope would be 0. This is because the cost (the y-value) does not change as the number of sodas (the x-value) increases. Thus, the correct answer is 1) 0.

The axis of symmetry for the function f(x) = -4(x - 8)^2 + 3 is x = 0.
Explanation:The axis of symmetry of a quadratic function can be found using the formula:
x = -b / (2a)
For the function f(x) = -4(x - 8)^2 + 3, the coefficient of the x^2 term is -4 (which is a) and the coefficient of the x term is 0 (which is b).
Therefore, the axis of symmetry can be found as:
