Answer:
Step-by-step explanation:
With a factor of (t - 1) we know that zero (ground level) is reached at 1 second from an initial height of (0 - 1)(0 - 1)(0 - 11)(0 - 13)/3 = -1•-1•-11•-13 / 3 = 47⅔ meters at t = 0
As we have two factors of (t - 1) we know the track does not go underground at t = 1, but rises again.
At t = 11 seconds, the car has again returned to ground level, but as we only have a single factor of (t - 11) the car plunges below ground level and returns to above ground level at t = 13 seconds due to the single factor of (t - 13)
we can estimate that the car is the deepest below ground level halfway between 11 and 13 s, so at t = 12. At that time, the depth will be about (12 - 1)(12 - 1)(12 - 11)(12 - 13) / 3 = -(11²/3) = - 40⅓ m.
we can estimate that the car is the highest above ground level halfway between 1 and 11 s, so at t = 6s. At that time, the height will be about (6 - 1)(6 - 1)(6 - 11)(6 - 13) / 3 = 5²•-5•-7 / 3 = 291⅔ m.
It's obvious that the roller coaster car had significant initial velocity at t = 0 to achieve that altitude from an initial height of 47⅔ m

Compute the required rate of return on two stocks with beta values of 0.5 and 2 respectively assuming the risk-
free rate of 5% and the market return of 10% using the capital asset pricing model. Please show work. Thank you.
The required rate of return for the stock with a beta of 0.5 is 7.5% and for the stock with a beta of 2 is 15%.
What is Rate of return?Rate of return is the amount of profit or loss earned on an investment over a certain period of time, expressed as a percentage of the initial investment or total asset value.
What is stock?A stock is a type of security that represents ownership in a company. Investors buy stocks to become shareholders and share in the company's profits and losses.
According to the given information:
The Capital Asset Pricing Model (CAPM) is expressed as:
R = Rf + beta*(Rm - Rf)
Where:
R = Required rate of return
Rf = Risk-free rate of return
beta = Beta coefficient (systematic risk)
Rm = Expected market return
Using the given values, we can compute the required rate of return for each stock:
Stock with beta of 0.5:
R = 5% + 0.5*(10% - 5%)
R = 7.5%
Stock with beta of 2:
R = 5% + 2*(10% - 5%)
R = 15%
Therefore, the required rate of return for the stock with beta of 0.5 is 7.5%, and the required rate of return for the stock with beta of 2 is 15%.

A recipe calls for 3 3/4 cups of flour. How much flour is needed if the recipe is tripled
The amount of flour that is needed if the recipe is tripled is 11 ¹ / ₄ cups of flour
How to find the flour needed for the recipe?To find the flour needed for the recipe, first convert the mixed fraction to an improper fraction for easier calculation.
= 3 ³ / ₄
= (4 x 3 + 3) / 4
= 15 / 4 cups of flour
If the recipe was tripled, then the number of cups of flour would also need to be tripled.
The amount of flour needed becomes:
= 15 / 4 x 3
= 45 / 4
= 11 .25
= 11 ²⁵ / ₁₀₀
= 11 ¹ / ₄ cups of flour

the top of an electric pole is s supported by a wire of 26 ft long on the ground level. how far is tightened spot from the foot of the pole if its height is 24 ft?
Answer:
The tightened spot is 10 feet away from the foot of the pole.
Step-by-step explanation:
1. Draw the diagram. Notice that the shape of the electric pole and its supporting wire creates a right triangle.
2. We know 2 side lengths already (26ft, 24ft), and we need to find 1 more side length. Therefore, to find the 3rd side length of a right-triangle, utilize Pythagoras' Theorem.
⭐What is the Pythagoras' Theorem?
\((C)^2 = (A)^2 + (B)^2\)An equation to find a 3rd side lengthC = hypotenuseA = one legB = another leg3. Substitute the values of the side lengths into the equation, and solve for the unknown side length.
Let B= the distance from the tightened spot to the foot of the pole.
\((C)^2 = (A)^2 + (B)^2\)
\(26^2 = 24^2 + B^2\)
\(676 = 576 + B^2\)
\(100 = B^2\)
\(\sqrt{100} = \sqrt{(B)^2}\)
\(10 = B\)
∴ The tightened spot is 10 feet away from the foot of the pole.

If 13 metres of a uniform iron rod weights 23.4 kg then what will be the weight of 6 metres of the same rod?
Answer:
Solution:
Here,
\(\begin{array}{ | c| c c | } \hline\ \ \text{length \: of \: iron \: rod}& \text{weight} \\ \hline 13 \rm{m}& \rm{23.4kg} \\ \hline \rm{6m}&?\\ \hline\end{array}\)
Weight of 13 m of rod=23.4 kg
Weight of 1 m of rod=23.4/13 kg
[less length,less weight]
Weight of 6 m of rod=23.4/13 ×6 kg=10.8 kg
[more length,more weight]
Thus,the weight of 6 m of rod is 10.8 kg.
Alternative method:
Let,the required weight be x kg.
Then,
\(\begin{array}{ | c| c c | } \hline\ \ \text{length \: of \: iron \: rod}& \text{weight} \\ \hline \rm{13m}& \rm{23.4 \: kg }\\ \hline \rm{6m}& \rm{x =? } \\ \hline\end{array}\)
We know that,
More length of iron rod(\(\red{\uparrow}\)) will have the more weight(\(\red{\uparrow}\)).
So,using the rule of direct proportion;
i.e. Ratio of length=Ratio of weight
\( \displaystyle{ \frac{13}{6} = \rm\frac{23.4}{x} }\)
\( \rm{13x = 6 \times 23.4}\)
\( \rm{x = \displaystyle{ \frac{6 \times 23.4}{13} }}\)
\( \therefore{x = 10.8}\)
Thus,the weight of 6 m long iron rod is 10.8 kg.

factorise x³-4x²+x+6
The binomial factors of x³- 4x²+x+6 are (x+2), (x+3), and (x-1).
Using the splitting and grouping the terms:
x³ + 4x² + x - 6
= x³ + 2x² + 2x² + x - 6 [Splitting 4x² = 2x² + 2x²]
= (x³ + 2x²) + (2x² + x - 6)
= x² (x + 2) + (2x² + 4x - 3x - 6)
= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]
= x² (x + 2) + (x + 2) (2x - 3)
= (x + 2) ( x² + 2x - 3)
= (x + 2) ( x² + 3x - x - 3)
= (x + 2) [x (x + 3) - 1 (x + 3)]
= (x + 2) (x + 3) (x - 1)

1. The following diagram shows part of the graph of y=p⋅sin(qx)+r. The point A (15, 2) is a maximum point and B(45, 1) is a minimum point. Find the value of p, q, and r.
Answer: y = (1/2)*sin(x*pi/30) + 3/2
Step-by-step explanation:
We have the equation:
y = p*sin(q*x) + r.
in this case, p is the amplitude, which is calculated as half of the difference between the value at the peak (the maximum) and the value at the troughs (the minimums).
q is related to the period
r is the mid value of the function, will be equal to the minimum plus the amplitude (or the maximum minus the amplitude).
We know that the maximum is (15, 2) (x = 15, y = 2)
We know that the minimum is (45, 1) (x = 45, y = 1)
Then the value of y at the peak is 2, and the value of y at the trough is 1.
This means that the amplitude is:
p = (2 - 1)/2 = (1/2)
And we know that r is equal to the minimum plus one time the amplitude, then:
r = 1 + 1/2 = 3/2.
Then, for now, our equation is:
y = (1/2)*sin(q*x) + 3/2.
Now we can use the information that (15, 2) is a maximum.
We know that the maximum value of the function sin(x) is 1.
and it is when:
x = (pi/2) + n*2*pi (where n is a whole number)
Then we must have that:
15*q = (pi/2) + n*2*pi
as this is periodic, we can define n = 0 and it will be the same.
15*q = pi/2
q = (pi/2)/15 = pi/30.
Now, let's test this with the minimum.
The minimum of the sin(x) function is when:
x = (3/2)*pi + k*2*pi (where k can be any whole number)
and we have a minimum at x = 45, then:
q*45 = (3/2)*pi + k*2*pi
(pi/30)*45 = (3/2)*pi + k*2*pi
(45/30) = (3/2) + k*2
3/2 = 3/2 + k*2
If we take k = 0, then the equality is true
Then q = pi/30 is consistent.
So we can conclude that the equation is:
y = (1/2)*sin(x*pi/30) + 3/2

How long is line UW?
Answer: UW= 9√3
Step-by-step explanation:
This right triangle is a 30-60-90 triangle. This is a special triangle. Since this is a special triangle, the hypotenuse is 2x.
The hypotenuse is 18. We can figure out the length of x.
2x=18
x=9
Since we got 9, you would think it is the answer, but it's not. The length across the 60° angle is x√3. Now that we know the length across from 60°, we can plug in x.
9√3
We can check our answer by using Pythagorean Theorem.
9²+(9√3)²=18²
81+243=18²
