Answer:

D. Only one of the balls was yellow.

Step-by-step explanation:

red balls  yellow balls red balls.

Only one of the balls was yellow. Then the correct option is D.

Determining the proper option, acquiring evidence, and exploring various options are all steps in the decision-making process.

Three balls – each of which is either red or yellow, lie in a straight line on a pool table.

Adam strikes the first ball, which is red.

That ball hits the middle ball.

The middle ball then hits the last ball, which is yellow.

Only one of the balls was yellow.

Because the yellow ball is hit by the other ball.

Then the correct option is D.

Answer:

0.253 m/s

Step-by-step explanation:

radius r of the circular rise = 13 mm = 0.013 m

apparent weight loss = 50%

acceleration of the new weight = 0.5 x 9.81 = 4.905 m/s^2

centripetal acceleration = 9.81 -  4.905 =  4.905 m/s^2

centripetal acceleration = \(\frac{v^{2} }{r}\)

where v is the acceleration at the rise and r is the radius of the rise

centripetal force = \(\frac{v^{2} }{r}\)  = \(\frac{v^{2} }{0.013}\)

4.905 = \(\frac{v^{2} }{0.013}\)

\(v^{2}\) = 0.063765

v = \(\sqrt{0.063765}\) = 0.253 m/s

Answer:

Part A

The amplitude of a cosine function is the distance between its highest and lowest points. In this case, the highest point is 8 feet and the lowest point is 8 - 12 = -4 feet, so the amplitude is 8 - (-4) = 12 feet.

The period of a cosine function is the time it takes for the function to complete one cycle of its movement. In this case, the bird completes one cycle of its movement every 16 seconds, so the period is 16 seconds.

Part B

The cosine function that could represent the situation is:

y = 6 cos(2πt / 16) + 8

This function has an amplitude of 6 feet and a period of 16 seconds. It also passes through the point (0, 8) when t = 0, which is the condition given in the problem.

Part C

The bird will reach its lowest height when the cosine function is equal to -6. This happens when 2πt / 16 = π / 2, or t = 4 seconds.

Here is a graph of the function:

The amount Missy Elliot should put aside each year to make payments

for tuition in 18 years time at is $2,757.45.

Year at which the child will start college = 18 years from now

Current annual cost of college = $7,500

The annual increase in tuition = 5%

Number of years of college = 4 years

Therefore;

\(A_{18} = \mathbf{7,500 \times \left(1+\dfrac{0.05}{1} \right)^{1 \times (18 )}} \approx 18,049.64\)

\(A_{19} = 7,500 \times \left(1+\dfrac{0.05}{1} \right)^{1 \times (18 +1)} \approx \mathbf{18,952.13}\)

\(A_{20} = 7,500 \times\left(1+\dfrac{0.05}{1} \right)^{1 \times (18 +2)} \approx \mathbf{19,899.73}\)

\(A_{21} = 7,500 \times \left(\left(1+\dfrac{0.05}{1} \right)^{1 \times (18 + 3)} \approx \mathbf{20,894.72}\)

The total cost ≈ 18,049.64 + 18,952.13 + 19,899.73 + 20,894.72 = 77796.22

The percentage earned annually = 6%

Therefore;

The present value is therefore;

\(PV = \mathbf{\dfrac{77796.22 }{\left(1+0.06 \right)^{17} }} = 28,890.75\)

The annual payments are therefore;

\(Annual \ payment = \dfrac{28,890.75 \cdot \left(0.06\right) \cdot \left(1+0.06 \right)^{17} }{\left(1+0.06 \right)^{17} - 1} \approx \mathbf{2,757.45}\)

The amount Mizzy Elliot should put aside each year is therefore approximately $2,757.45

The relationship between the quantities shown in the table is +10. The values in column 2 (y) are obtained by adding 10 to the corresponding values in column 1 (x).

In the given table, the values in column 1 (labeled "x") are 1, 2, 3, and 4. The values in column 2 (labeled "y") are 11, 22, 33, and 44.

To determine the relationship between the quantities in the table, we can compare the values in column 2 (y) with the corresponding values in column 1 (x).

If we subtract each value in column 1 from the corresponding value in column 2, we find that:

11 - 1 = 10

22 - 2 = 20

33 - 3 = 30

44 - 4 = 40

By observing these results, we can see that the difference between each value in column 2 and its corresponding value in column 1 is always 10.

A member of the senate will serve for (h+4) years.

An expression, in mathematics, is a finite set of combinations and/ or numbers and variables that accurately represents the the context in question. When two or more expressions are connected using the equality sign then an equation is formed.

Here, we are given that in the US government a member of the senate serves for 4 years longer than a member of the House of Representatives.

Also the House of Representatives serves for- h years

Thus, the number of years a member of the Senate will serve will be 4 more than the number h

= h + 4

Thus, a member of the senate serves for (h+4) years.

Step-by-step explanation:

Lets break this word problem down:

"The difference" means we're going to be finding x - y ("difference" means we're finding how much one value "differs" from the other)

"a number and it's opposite" so we're doing x - y, where y = -x. So already, we can re-write this as x - (-x) or x + x

"is 28" so x + x = 28 ("is" always means "equals")

"Find the number" so we're finding x.

x - (-x) = 28  (I went back a step so I could write everything out more plainly)

simplify

x + x = 28

add

2x = 28

divide both sides by 2 to get x on its own

x = 14

The equation for a transformed cosine wave with the following properties is  y = 3cos2x + 4

An equation for a transformed cosine wave with the following properties can be written in the form:

y = A× cos(B(x - C)) + D

Where:

A = amplitude (positive value)

C = phase shift (horizontal shift of the wave)

D = vertical shift (shift of the wave up or down)

Here we have

Amplitude = 3

Period = π

Horizontal shift = None

Vertical shift  = 4 units  up  

As we know Period P = 2π/B

From the data => 2π/B = π

=> B = 2  

Hence,

Equation for a transformed cosine wave, y = 3 × cos(2(x - 0)) + 4

=> y = 3 × cos(2(x )) + 4

=> y = 3cos2x + 4  

Therefore,

The equation for a transformed cosine wave with the following properties is  y = 3cos2x + 4

u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹

We are given that:

log 4 ^ u - log 8 ^ v = 1

This can also be written in another way using the logarithm properties. We get that:

u log 4 - v log 8 = 1

Subtract v log 8 from both the sides:

u log 4 = 1 + v log 8

v log 8 = u log 4 - 1

v = ( u log 4 - 1 ) / log 8

v = u log (- 4 ) - ( log 8) ⁻¹

Therefore, we get that, u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹

Answer:  B

Step-by-step explanation:

In order to find out if the functions are continuous at 0, you must plug in 0 into both of the piecewise equations.  If the answers are the same then they are continuous at 0 if they are different then it is not continuous.

e× + 1

e⁰ + 1

1 +1

2

2 + sin x

2 + sin 0

2 + 0

Since the first part equation =2 when x=0 and the second part equation =0 when x=0, the functions would be continuous because they are the same.   But because there is no ≤ or ≥ there is no value for x=0.  It's been removed.

Your answer is B

Answer:  Choice B

The function f is continuous on  \((-\infty,0) \cup (0,\infty)\)

There is a removable discontinuity at x = 0.

====================================================

Explanation:

Let

\(g(\text{x}) = e^{\text{x}}+1\\h(\text{x}) = 2+\sin({\text{x}})\\\)

The f(x) function changes its identity based on what the input x would be.

If x < 0, then f(x) = g(x)

If x > 0, then f(x) = h(x)

Plug x = 0 into g(x)

\(g(\text{x}) = e^{\text{x}}+1\\g(0) = e^{0}+1\\g(0) = 1+1\\g(0) = 2\\\)

Do the same for h(x)

\(h(\text{x}) = 2+\sin({\text{x}})\\h(0) = 2+\sin(0)\\h(0) = 2+0\\h(0) = 2\\\)

Both functions produce the same output (2) when x = 0. Therefore, the two pieces are connected. Both pieces approach y = 2 when x gets closer and closer to zero. But we'll have an open hole at x = 0 since neither piece is defined when x = 0. This makes f(0) undefined. We have a removable discontinuity at x = 0. This is in contrast to a jump discontinuity where the two pieces do not approach the same y value.

To express this in interval notation, start with the set of real numbers \((-\infty,\infty)\) and poke a hole at x = 0 to remove it.

We'll end up with \((-\infty,0) \cup (0,\infty)\) as the domain and where f(x) is continuous.

v. 58°

Step-by-step explanation:

The trigonometric functions are given as:

Sin θ = \(\frac{opposite}{hypotenus}\)

Cos θ = \(\frac{adjacent}{hypotenuse}\)

Tan θ = \(\frac{opposite}{adjacent}\)

Thus,

i. adjacent leg / hypotenuse = 0.139 = Cos θ

θ = \(Cos^{-1}\) 0.139

  = 82°

ii. opposite leg / adjacent leg = 0.249 = Tan θ

θ = \(Tan^{-1}\) 0.249

  = 14°

iii. opposite leg / hypotenuse = 0.469 = Sin θ

θ  = \(Sin^{-1}\) 0.469

   = 28°

iv. adjacent leg / hypotenuse = 0.682 = Cos θ

θ = \(Cos^{-1}\) 0.682

   = 47°

v. opposite leg / hypotenuse 0.848 = Sin θ

θ  = \(Sin^{-1}\)  0.848
