Considering the given equation for the time, it is found that the length of the pendulum in this problem is of 38.40 ft.
What is the equation for the time it takes for the pendulum to swing back and forth?The equation is given as follows:
[tex]f(l) = 2\pi\frac{l}{32}[/tex]
In which l is the length of the pendulum.
In this problem, we have that [tex]f(l) = 2.4\pi[/tex], hence:
[tex]f(l) = 2\pi\frac{l}{32}[/tex]
[tex]2.4\pi = 2\pi\frac{l}{32}[/tex]
l = 32 x 1.2
l = 38.4 ft.

Claudia is making a candle by pouring melted wax into a mold in the shape of a cylinder. The radius of the cylinder’s base is 4 cm, and the height of the cylinder is 9 cm. To get the wax for the candle, Claudia melts cubes of wax that are each 3 cm by 3 cm by 3 cm. How many of the wax cubes will Claudia need to purchase to make the candle? (Note that Claudia is not able to purchase partial cubes). Show all your work.
The formula of a cylinder is 2πr (r+h)
2π4 (4+9)
8π (13)
25.13 (13)
326.73
Cubes: area = a^3
3x3x3 = 27
326.73 / 27 = 12.1
Claudia would need to buy 13 wax cubes to fil the candle.

I need help 20 points
Answer:
[tex]A = 9\pi[/tex]
Step-by-step explanation:
This is basically just 3/4 of a circle, so the area will be:
[tex]A = \frac{3}{4} \pi r^{2}[/tex]
Plug in 6 for the radius:
[tex]A = \frac{3}{4} \pi (6)^{2}[/tex]
Simplify:
[tex]A = \frac{3}{4} \pi (36)[/tex]
Simplify further:
[tex]A = 9\pi[/tex]

caleb is choosing a bank from the two banks below in an average month he writes 12 checks use his debit card 10 times and uses the atm six times how much caleb send on his monthly bank fees at state bank six times
Based on the number of times that Caleb writes checks, uses his debit card, and uses the ATM, his monthly bank fees are $11 and $15.70 at NeoBank and Arbor Bank respectively.
What are Caleb's bank fees?The question is incomplete so I will use a similar question to answer it.
Caleb's fees at Neobank would be:
= (12 checks x 0 per check) + (10 debt card uses x 0 per use) + (6 ATM uses x 1 per use) + 5 Monthly fee
= 0 + 0 + 6 + 5
= $11
Caleb's fees at Arbor Bank:
= (12 checks x 0.10 per check) + (10 debt card uses x 0.25 per use) + (6 ATM uses x 2 per use) + 0 Monthly fee
= $15.70

There are 60 cubic units in the provided three-dimensional figure, and the units are mm³, cm³, and m³.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have a three-dimensional shape shown in the picture with dimensions.
The total cubic units = 4×3×5 = 60 cubic cm
We can measure the volume with units of mm³, cm³, m³, km³
We can draw a relation between them:
mm³<cm³ <m³< km³
For the first picture, the unit mm³ would be best for measuring the volume.
For the second picture, the unit cm³ would be best for measuring the volume.
For the third picture, the unit m³ would be best for measuring the volume.
Thus, there are 60 cubic units in the provided three-dimensional figure, and the units are mm³, cm³, and m³.

After all the games, the point tallies were as follows: Team A won 22 points, team B won 19 points, team C won 14 points, and team D won 12 points. How many games ended in a tie?
The number of game that ended in a tie are= 67
Calculation of total number of tiesThe number of points that makes up a win = 3
The number of points that makes up a tie = 1
The number of points that makes a loss = 0
Team A = 22 points
Team B = 19 points
Team C = 14 points
Team D = 12 points
The total of points gotten by the whole team is = the games that ended in a tie.

6) Which of the following equations is of a parabola with a vertex at (3, 0)?
a) y = x2 + 3
b) y = x2-3
c) y = ( x + 3) 2
d) y = ( x - 3)2
Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
We need a parabola with a vertex at (0,-3)
If we select the equation:
[tex]y=x^2-3[/tex]
When we put x = 0, we get
[tex]y=0-3[/tex]
[tex]y=-3[/tex]
And similarly, when we put y = -3, we get
[tex]-3=x^2-3[/tex]
[tex]0=x^2[/tex]
[tex]x=0[/tex]
Hence, second option is correct.
