Suppose that G(x) = F(x - 8). Which statement best compares the graph of G(x) with the graph of F(x)? apex
A.The graph of G(x) is the graph of F(x) shifted 8 units to the right.
B.The graph of G(x) is the graph of F(x) shifted 8 units to the left.
C.The graph of G(x) is the graph of F(x) shifted 8 units up.
D.The graph of G(x) is the graph of F(x) shifted 8 units down.

Answers

Answer:

Step-by-step explanation:

The graph of G(x) = F(x - 8) is the graph of F(x) shifted 8 units to the right, option A.

When comparing the graph of G(x) = F(x - 8) with the graph of F(x), we note that there is a horizontal shift involved. Following the rules for transformations, subtracting a positive constant from the independent variable x results in shifting the graph to the right by that constant. Therefore, the statement that best compares the graph of G(x) with the graph of F(x) is: The graph of G(x) is the graph of F(x) shifted 8 units to the right, option A.

This is similar to the effect observed when comparing the functions f(x) and f(x - 2), where the latter's graph is a rightward shift of the former's graph by 2 units.

There are 10 single-digits (0 through 9) and 26 letters (A through Z)

For the first slot there are 10 choices which represents selecting a single digit
For the second slot there are 26 choices because we choose a single letter here.

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, the angle of depression to the boat is 17°31'. When the boat stops, the angle of depression is 46°41'. The lighthouse is 200 feet tall. How far did the boat travel from when it was first noticed until it stopped? Round your answer to the hundredths place.

Answers

The tangent of the angle gives the ratio of the height of the lighthouse to the boat's distance
.. tan(angle of depression) = (lighthouse height)/(boat distance)
Then the distance to the boat is
.. boat distance = (lighthouse height)/tan(angle of depression)

We want to find the difference between two distances, so
.. boat travel = (lighthouse height)*(1/tan(first angle) -1/(tan(second angle))
.. = (200 ft)*(1/tan(17°31') -1/tan(46°41'))
.. ≈ 445.10 ft

Final answer:

By using the tangent function and the angles of depression given, we can calculate the distances from the boat to the lighthouse when it was first spotted and when it stopped. Subtracting the second distance from the first gives us the distance the boat traveled.

Explanation:

This is a question about Trigonometry, involving the concepts of angles of depression and distances. In the situation presented, we are given the height of the lighthouse (200 feet), and two angles of depression - 17°31' when the boat was first noticed and 46°41' when the boat stopped. We can use the tangent function to calculate the distance from the lighthouse to the boat at these two points, then subtract these distances to find how far the boat traveled.

The tangent of an angle in a right triangle is equal to the opposite side divided by the adjacent side. Therefore, when the angle of depression was 17°31', we can use the equation tan(17°31') = 200/distance1 to solve for the first distance. Similarly, for the angle of depression 46°41', we use the equation tan(46°41') = 200/distance2.

Solving these two equations separately will give us the distances from the boat to the lighthouse at these two moments. Then we subtract distance2 from distance1 to get the distance the boat traveled.

A animal shelter has 16 puppies. If the puppies are 32% of the total dogs and cats population, how many dogs and cats are in the animal shelter?

Answers

32%=16
100%=[tex] \frac{100}{32} *16=50animals[/tex]

The total number of animals in a shelter is 50 and number of cats in the shelter is 34.

Given that, a animal shelter has 16 puppies. If the puppies are 32% of the total dogs and cats population.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let x be the total number of dogs and cats are in the animal shelter.

So, 32% of x=16

⇒ 32/100 ×x=16

⇒ 0.32x=16

⇒ x=16/0.32

⇒ x=50

So, number of cats =50-16

= 34

Therefore, the total number of animals in a shelter is 50 and number of cats in the shelter is 34.

To find the probability of selecting 3 green marbles out of 10, use the combinations formula. The calculation involves 455 * 6435 divided by 1027227812 to determine the probability.

Explanation:

To calculate the probability of choosing exactly 3 green marbles out of 10 selected, we use the concept of combinations. The formula for combinations is nCr = n! / r!(n-r)!. In this case, the calculation would be 15C3 * 35C7 / 50C10, which simplifies to 455 * 6435 / 1027227812, resulting in the probability of choosing exactly 3 green marbles out of 10 selected.

Answers

We must solve the system in order to find an answer.
Let's solve the system of equations:
[tex]x + y = 24\\ 3x + 5y = 100[/tex]
Now let us multiply the first equation by -3:
[tex]x + y = 24/\cdot(-3)\\ 3x + 5y = 100\\ --------\\ -3x-3y=-72\\ 3x + 5y = 100 [/tex]
We add those two equations together( 3x-3x will cancel out):
[tex]-3x-3y=-72\\+ 3x + 5y = 100\\ --------(+)\\ 2y=28\\ y=14 [/tex]
Now we simply plug y=14 into any of the starting equations to find x:
[tex]x + y = 24\\ x+14=24\\ x=10[/tex]

ABCD is a rectangle. Find the length of each diagonal.

Answers

Answer: The correct answer is 3

Step-by-step explanation:

C = 3

AC = 3/3 = 1

BD = 4 - 3 = 1

The length of each diagonal is 12/5. This demonstrates that in a rectangle, the diagonals are always equal in length.

In a rectangle, the diagonals are equal in length. Therefore, we can equate [tex]$AC$ and $BD$[/tex].

Given [tex]$AC = \frac{C}{3}$ and $BD = 4 - C$[/tex], we set them equal: [tex]$\frac{C}{3} = 4 - C$[/tex]. Solving for $C$ yields [tex]$C = \frac{12}{5}$[/tex].

Substituting this value back into either [tex]$AC$ or $BD$[/tex] gives us the length of the diagonals.

Thus, the length of each diagonal is [tex]$AC = BD = \frac{12}{5}$[/tex]. This demonstrates that in a rectangle, the diagonals are always equal in length.

How would you factor 4x^2 + 9?
I think the answer has imaginary numbers in it, but how would you get the solution?

Answers

The answer is it cannot be. It is because if you use the difference of two square, the operation used must not be addition, but it would be subtraction.
It can be factored out if you will find the factors of 4x^2 - 9 =0
So the factors will be(using difference of two perfect squares):
(2x+3)(2x-3)
Cause if you will use the factors (2x+3)(2x+3) or even the negative signs to it, it will give:
4x^2+12x+9 or 4x^2-12x-9

Write an inequality to represent the situation: The temperature stayed above -15 degrees. Help!

It is given temperature stayed above -15 degrees.

This can be written in inequality form as t> -15 °(degrees)

The inequality to represent the temperature is t > -15°C

Given data:

To represent the situation where the temperature stayed above -15 degrees, the inequality symbol used is ">".

In an inequality, the ">" symbol means "greater than." By using this symbol, the temperature needs to be greater than -15 degrees.

The inequality representing this situation is:

Temperature > -15°C

So, t > -15°C

If the temperature is higher than -15 degrees, the inequality is true.
