The Torque function is T(t) = 3sin((t-5)π/30).
What is Torque?When an engine exerts itself, torque, which is a twisting force, speaks to the rotational force of the engine and quantifies how much of that twisting force is accessible.
Given:
After 5 minutes Thomas ties it on, the torque is zero and increasing.
So, the sine function is shifted right 5 minutes.
and, The maximum value is 3.
Then, the multiplier of the sine function as the period is 60 minutes
Then, the coefficient of t = (2π/60)
= π/30.
Hence, the Torque function is T(t) = 3sin((t-5)π/30).

The base of an open rectangular box is of length (2x + 5) cm and width x cm.
The area of this base is 58 cm
The height of the open box is (x - 2) cm.
a) Show that 2x + 5x -58 = 0
) Solve the equation 2x + 5x -58 = 0, giving your answers correct
to 2 decimal places
D) Hence calculate the volume of the box, stating the units of your answer.
Answer:
a) x = 8.29 cm
D) V = 1125.27 cm³
Step-by-step explanation:
a) We can solve the equation as follows:
[tex] 2x + 5x - 58 = 0 [/tex]
[tex] 2x + 5x = 58 [/tex]
[tex] x = \frac{58}{7} = 8.29 [/tex]
D) The volume of the box is given by:
[tex] V = l*w*h [/tex]
Where:
l: is the length
w: is the width
h: is the height
The length of the rectangular box is:
[tex] l = (2x + 5) cm = (2*8.29 + 5) cm = 21.58 cm [/tex]
The width is x = 8.29 cm.
And the height is:
[tex] h = (x - 2) cm = (8.29 - 2) cm = 6.29 cm [/tex]
Hence, the volume is:
[tex] V = l*w*h = (21.58*8.29*6.29) cm^{3} = 1125.27 cm^{3} [/tex]

8p²-18p² need help from brainliest
Answer:
- 10p2
Step-by-step explanation:
p(8p - 18 p)
p x -10p
ans = -10p2
Answer: -10p²
This is the same as saying -10p^2
============================================
Explanation:
Both terms 8p² and -18p² are like terms.
We combine them in much the same way as 8-18 = -10, just with a p² attached to everything.
So 8p² - 18p² = (8-18)p² = -10p²
The coefficient -10 is negative because we're subtracting small minus big. If it was the other way around, then we'd get a positive value.

what is the 1QR 14,11,8,1,23,20,17,5,19,10,12,22
Answer:
Step 1: Put the numbers in order.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 2: Find the median.
1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.
Step 3: Place parentheses around the numbers above and below the median.
Not necessary statistically, but it makes Q1 and Q3 easier to spot.
(1, 2, 5, 6, 7), 9, (12, 15, 18, 19, 27).
Step 4: Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
(1, 2, 5, 6, 7), 9, ( 12, 15, 18, 19, 27). Q1 = 5 and Q3 = 18.
Step 5: Subtract Q1 from Q3 to find the interquartile range.
18 – 5 = 13.

What is the maximum value of the objective function, P, with the given constraints? P=25x+45y 4x+y≤16 x+y≤10 x≥0 y≥0
Answer:
the maximum is 450 and the minimum is 0.
Step-by-step explanation:
We know that:
P(x, y) = 25*x + 45*y
First, is easy to see that as x and y increase, also does the value of P(x, y)
So we just need to find the largest and smallest possible values of these variables. We also can notice that the variable y is being multiplicated by a larger coefficient than x, so we prioritize larger values of y when we can.
We know that:
4x+y ≤ 16
x + y ≤10
x≥0
y≥0
Let's start with the second inequality, let's solve this for y:
y ≤ 10 - x
and from the first one we get:
y ≤ 16 - 4*x
Just to show that maximizing x does not work, let's do it:
from the second one, knowing that the minimum value of y is y = 0
we have that:
0 ≤ 16 - 4*x
Here the maximum value that y can take is x = 1
0 ≤ 16 - 4*1 = 0
So we can have the combination y = 0 and x = 1, when we maximize x (here we can see that we should not maximize x)
in this case we get:
P(1, 0) = 25*1 + 47*0 = 25
let's write again our inequalities:
y ≤ 10 - x
y ≤ 16 - 4*x
If now we take the minimum value of x, x = 0, we get:
y ≤ 10
y ≤ 16
Because the first one is more restrictive, we know that the maximum value that y can take (when x = 0) is y = 10
in this case we get:
P(0, 10) = 25*0 + 45*10 = 450
As expected, here is the actual maximum for the given restrictions.
For the minimum, we just need to take the two lowest possible values of x and y, which are the two given by the equalities on:
x≥0
y≥0
The smallest values are:
x = 0
y = 0
Replacing that in the equation we get:
P(0, 0) = 25*0 + 47*0 = 0
So the maximum is 450 and the minimum is 0. (with the given restrictions)

Step-by-step explanation:
[tex] \frac{3}{2} + \frac{x}{3} = \frac{11}{6} [/tex]
[tex] \frac{x}{3} = \frac{11}{6} - \frac{3}{2} [/tex]
[tex] \frac{x}{3} = \frac{11 - 3 \times 3}{6} [/tex]
[tex] \frac{x}{3} = \frac{11 - 9}{6} [/tex]

[tex]x = \frac{3 \times 1}{3} [/tex]
[tex]x = 1[/tex]
Answer:
x = 1
Step-by-step explanation:
3/ 2 + x/ 3 = 11/ 6
taking LCM
(9 + 2x)/ 6 = 11/ 6
multpiying both sides by 6
9 + 2x = 11
subtracting btih sides by 9
2x = 11 - 9
2x = 2
dividing both by 2
x = 1

PLEASE HELP ASAP!!!!
Jackson is testing different types of planting soil to determine which type is most effective for growing strawberry bushes. He purchases two different brands of planting soil from a local store. Jackson applies brand A to an area of the yard that receives full sunlight and brand B to another area of the yard that is in partial sunlight. He waters the area with brand B daily; he waters the area with brand A every other day. At the end of the study, Jackson concludes brand A is more effective in growing strawberry bushes. Is Jackson's conclusion valid? Explain why or why not.
Answer:
It is not valid since there is more than one variable being changed at one.
Step-by-step explanation:
Jackson changed the brand of soil, but he also changes the amount of water, and the amount of sunlight the plants are receiving, so his conclusion that the soil was more effective is not valid.
Answer:
No, Jackson did not take into account alternate theories.
Jackson's findings could have been influenced by the watering schedule and the amount of sunlight. Without adjusting for these variables, the experiment is inconclusive.
simplify:- the following fraction
Whole part = 2
Fractional part = 59/396
======================================================
Work Shown:
3 & 3/5 = 3 + 3/5
3 & 3/5 = 15/5 + 3/5
3 & 3/5 = 18/5
--------------------
4 & 8/9 = 4 + 8/9
4 & 8/9 = 36/9 + 8/9
4 & 8/9 = 44/9
--------------------
Now apply the rule that 1/(A/B) = B/A. We apply the reciprocal to the fraction A/B to get B/A
That means something like 1/(18/5) becomes 5/18
Also, 1 over (44/9) becomes 9/44
1 over (3/5) becomes 5/3
-------------------
We now have the following:
(5/18) + (9/44) + (5/3)
We'll come back to this later. But first need the LCD, which means we need the LCM of the denominators.
Write out the prime factorization of each denominator
18 = 2*3*344 = 2*2*113 = 1*3The unique prime factors are: 2, 3, 11
We have 2 occur at most twice, so 2^2 is part of the LCM.We have 3 occur at most twice, so 3^2 is part of the LCMWe have 11 occur at most 1 time, so 11^1 is part of the LCMThe LCM is 2^2*3^3*11^1 = 1188, which is also the LCD
-------------------
We need to get each fraction to have the LCD
5/18 = (5/18)*(66/66) = 330/1188
9/44 = (9/44)*(27/27) = 243/1188
5/3 = (5/3)*(396/396) = 1980/1188
We can now add the fractions like so
(5/18) + (9/44) + (5/3)
(330/1188) + (243/1188) + (1980/1188)
(330+243+1980)/1188
2553/1188
-------------------
We're almost done. We just need to convert to a mixed number, aka mixed fraction
Using a calculator or long division, you should find that
2553/1188 = 2.1489898989899
approximately. Focus just on the stuff to the left of the decimal point. That's the whole part of the answer.
We can then say: 2553-1188*2 = 177
This forms the numerator of the fractional part. The denominator stays at the LCD 1188
That forms the fraction 177/1188. Divide both parts of that fraction by 3 to fully reduce it. You should get to 59/396
-------------------
So that's how we end up with the mixed number 2 & 59/396
