At 11:55 p.m., Thomas ties a weight to the minute hand of a clock. The clockwise torque applied by the
weight (i.e. the force it applies on the clock's hand to move clockwise) varies in a periodic way that can be
modeled by a trigonometric function.
The torque peaks 15 minutes after each whole hour, when the minute hand is pointing directly to the right,
at 3 Nm (Newton metre, the SI unit for torque). The minimum torque of -3 Nm occurs 15 minutes
before each whole hour, when the minute hand is pointing directly to the left.
Find the formula of the trigonometric functid that models the torque applied by the weight t minutes
after Thomas attached the weight. Define the function using radians.
T(t) =(
Answer:
T(t) = 3sin((t-5)π/30)
Step-by-step explanation:
5 minutes after Thomas ties it on, the torque is zero and increasing. So, the sine function is shifted right 5 minutes. The maximum value is 3, so that is the multiplier of the sine function. The period is 60 minutes, so the coefficient of t is (2π/60) = π/30. The function you want is ...
T(t) = 3sin((t-5)π/30)

You deposit $1500 in an account that pays 7% annual interest. Find the balance after 2 years when the interest is compounded daily.
Answer:
$1,725.39
Step-by-step explanation:
-Take 1 year =365 days.
#We calculate the effective interest rate for 7% compounded daily;
[tex]i_m=(1+i/m)^m-1\\\\=(1+0.07/365)^{365}-1\\\\=0.072501[/tex]
#We now use this rate to calculate the compounded amount after two years:
[tex]A=P(1+i_m)^n\\\\=1500(1.072501)^2\\\\=1725.39[/tex]
Hence, the balance after 2 years $1,725.39
To find the balance after 2 years with daily compounded interest, the formula [tex]A = P(1 + r/n)^(nt)[/tex] is used, with a principal of $1500, an annual rate of 7%, and n being 365. After calculations, the final balance would be approximately $1717.40.
Explanation:To calculate the balance after 2 years when the interest is compounded daily, we can use the formula for compound interest: A = P(1 + r/n)nt, where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial sum of money).r is the annual interest rate (in decimal form).n is the number of times that interest is compounded per unit t.t is the time the money is invested for in years.In your case, you deposit $1500 in an account that pays 7% annual interest. Since the interest is compounded daily, we will use 365 for n. Here's your calculation:
Convert the annual interest rate from a percentage to a decimal by dividing by 100: 7% / 100 = 0.07.Calculate the balance using the compound interest formula: A = 1500(1 + 0.07/365)(365)(2).Compute the value of (1 + 0.07/365) and then raise it to the power of 730 (which is 365 days times 2 years).The resulting amount is the new balance in your account after 2 years, including the interest that was compounded daily.After doing the math, your compounded balance after 2 years will be approximately:
A = 1500(1 + 0.07/365)730
A ≈ $1500 * 1.14493150684931506849
A ≈ $1717.40
This means that after 2 years, you will have approximately $1717.40.

D) vertical asymptotes x = −4, 2
Help please! 50 points!
Answer:
D) vertical asymptotes x = −4, 2
Step-by-step explanation:
First you factor the denominator: x^2 +2x−8
Find factors of -8(c) that add together to give 2(b): 4 and -2
Rewrite the equation: x^2+4x-2x-8
Factor out common variables: x(x+4)-2(x+4)
Group the things inside and outside the parentheses together: (x-2)(x+4)
Solve: x-2=0 so x=2 and x+4=0 so x=-4
Answer:
D) vertical asymptotes x = −4, 2
Step-by-step explanation:
x² + 2x - 8 = 0

The volume of gas varies inversely as the pressure. A volume of gas is 120 cubic feet under 6 pounds of pressure. What is the volume at the same temperature when the pressure is 8 pounds?
The volume of gas is 80 cubic feet at the same temperature when the pressure is 8 pounds.
Step-by-step explanation:
The given is,
Volume of gas is 120 cubic feet under 6 pounds of pressure.
Volume of gas varies inversely as the pressure.
Pressure is 8 pounds
Step:1
From the given,
Volume of gas varies inversely as the pressure,
[tex]P_{gas}[/tex] ∝ [tex]\frac{1}{V_{gas} }[/tex].......................................(1)
Ratio of volume to pressure of gas is,
= [tex]\frac{120}{6}[/tex] = 20
Step:2
Pressure of gas is increased 6 to 8 pounds,
Change in pressure = 8 - 6 = 2 pounds
Change in volume = Ratio × change in pressure
= 20 × 2 = 40 cubic feet
Step:3
From the equation (1),
The pressure is increased, the volume of gas is reduced.
Volume of gas at pressure of 8 pounds = 120 - 40
= 80 cubic feet
Result:
The volume of gas is 80 cubic feet at the same temperature when the pressure is 8 pounds.

In ΔFGH, the measure of ∠H=90°, HG = 48, FH = 55, and GF = 73. What ratio represents the tangent of ∠G?
Answer:
55/48
Step-by-step explanation:
We can find the tangent of ∠G using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
Considering triangle ΔFGH, where ∠H=90°
The opposite side is FH, the hypotenuse side is GF and the adjacent side is HG hence,
Tan ∠G = FH/HG
= 55/48
Answer:
55:48
Step-by-step explanation:
Given a right angles triangle ∆FGH
where ∠H=90°, HG = 48, FH = 55, and GF = 73,
Based on the diagram attached
To find the tangent of angle G, we will use the concept of SOH CAH TOA in trigonometry identity.
According to TOA:
Tan ∠G = Opposite/Adjacent
Note that the opposite side will be the side facing the angle we are considering i.e ∠G
Opposite = 55
Adjacent will be the base of the triangle = 48
Tan∠G = 55/48
The ratio that represents the tangent of ∠G is 55:48

Answer:
b) observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses.
d) taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch.
Step-by-step explanation:
These are the two options that are most likely to give you a sample that fairly represents the population. In the first case, the sample that you obtain is likely to be a good representation because Main Street is a road where a great variety of people walk. Moreover, 5 pm is also a time that will allow you to see a great number of different people. The second answer will also give you a good sample, as the poll would include all students in the lunch room, which is all students in the school (the whole population).
A truck is carrying 100 pounds of grapes, which are 99% water (and 1% skin, fiber, etc…). When the truck breaks down and the grapes sit in the back of the truck for 4 hours, they become 98% water. At that moment, how many pounds do the grapes weigh?
Answer:
The grapes have a weight of 50 pounds
Step-by-step explanation:
To calculate the weight of the grapes, we proceed as follows;
Let's categorize the skin, fiber as solids
At first, we had 1% solids and 99% water.
This means 99 pounds of water and 1 pound of solid
It must be known that the 1% solid remains the same after drying and what we have lost simply is the water,
This means that 2% of the total weight is now same 1 pound of solid after drying
Mathematically, this means
2/100 * new total weight = 1 pound
New total weight = 1 pound × 100/2 = 50 pounds

Bus A and Bus B leave the bus depot at 7 am. Bus A takes 25 minutes to do its route and bus B takes 40 minutes to complete its route. At what time are they both back at the bus depot together?
Bus A and Bus B leave the bus depot at 7 am. At 10:20 AM are they both back at the bus depot together.
Given:
Bus A takes 25 minutes to complete its route once Bus B takes 40 minutes to complete its route To find time when they will be back at the bus depot together we need to find LCM of 25 & 40 Minutes=> 25 = 5 * 5
=> 40 = 2 * 2 * 2 * 5
LCM = 2 * 2 * 2 * 5 * 5=> = 200
Thus, After 200 minutes Buses will be back at the bus depot together
200 minutes = 3 hr 20 Minutes 7 : AM + 3 hr 20 Minutes => = 10 : 20 AMThus, At 10: 20 AM Buses would be back at the bus depot together.

Bus A and Bus B will both be back at the depot at the same time at 10:20am.
Explanation:To solve the problem, we need to determine when both Bus A and Bus B will be back at the depot at the same time. Since Bus A takes 25 minutes to complete its route and Bus B takes 40 minutes, we need to find the common multiple of these two numbers. The smallest common multiple of 25 and 40 is 200. This means that both buses will be back at the depot at the same time after 200 minutes.
Since the buses leave the depot at 7:00 am, we add 200 minutes (or 3 hours and 20 minutes) to this time. Therefore, it's at 10:20 am that both buses are back at the depot at the same time.

(D)The mean number of points per player per game is the same at all 3 schools.
In college basketball, the mean and median number of points per player per game can be different depending on the scoring distribution of the team. At Dartmouth, the mean is greater than the median due to players scoring different points. At Maryland, the mean is also greater than the median due to a few players scoring higher points. The median and mean can vary across different schools and teams.
Explanation:Choice A: At Dartmouth, the mean number of points per player per game is greater than the median number of points per player per game. The mean is calculated by summing up all the scores and dividing by the total number of players, while the median is the middle value when the scores are arranged in increasing order. With players scoring different points per game at Dartmouth, there will be players scoring more than the mean, pulling the mean up and making it greater than the median.
Choice B: At Maryland, the mean number of points per player per game is greater than the median number of points per player per game. With only a few players scoring points other than 0, these outlier scores will cause the mean to be greater than the median.
Choice C: The median number of points per player per game can be different at different schools. In the case of Dartmouth, the median could be greater than the mean due to a large number of players scoring the same lower points per game. In the case of Maryland, with a few players scoring higher points, the median could be lower than the mean.
Choice D: The mean number of points per player per game can be different at different schools, as explained in Choices A and B.

Find the missing length of the triangle.
5.6 in.
10.6 in.
Answer:
9 in
Step-by-step explanation:
The missing length of the right angle triangle is approximately 12 in.
The missing length of the right-angle triangle can be found using the Pythagorean theorem. The theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. In this case, the length of one side of the triangle is 5.6 in and the length of the other side is 10.6 in. Let's substitute these values into the formula:
a² + b² = c²
(5.6 in)² + (10.6 in)² = c²
31.36 in² + 112.36 in² = c²
143.72 in² = c²
Now, we can take the square root of both sides to find the length of the hypotenuse:
c = √143.72 in² ≈ 12 in
Therefore, the missing length of the right angle triangle is approximately 12 in.
