The true statement about the rate of change of the table is (c) The rate of change is 10. This means every 1 ticket sold produces a net profit of $10.00
How to determine the rate of changeFrom the table, we have the following ordered pairs
(x,y) = (150,-500) and (200,0)
The rate (r) is then calculated as:
[tex]r = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, the equation becomes
[tex]r = \frac{0 + 500}{200 - 150}[/tex]
Evaluate the difference and the sum
[tex]r = \frac{500}{50}[/tex]
Evaluate the quotient
[tex]r = 10[/tex]
The value of the rate represents that for every 1 ticket sold, there is a net profit of $10

Since,

The Length of one side is (2x + 3)James is flipping a coin twice. He says the probability that he’ll get tails both times is 1/2. Which of these is true?
James flipping the coin is an illustration of probability
James' claim is false
How to determine the true statement
The sample space of a coin is:
S = {H,T}
So, the probability of obtaining a tail is:
P(T) = n(T)/n(S)
This gives
P(T) = 1/2
When the coin is flipped twice, the probability that he’ll get tails both times is
P(T and T) = 1/2 * 1/2
Evaluate the product
P(T and T) = 1/4
From the question, he says the probability that he’ll get tails both times is 1/2.
Hence, James' claim is false

A car valued at $14,000 depreciated 18% per year. After how many years will the value have depreciated to $1000?
Answer:
Little more than 5 years
Step-by-step explanation:
Given the following question:
Original value of the car is $14,000
18% depreciated or diminish in value per year.
How many years would it take for the cars value to reach $1000?
To find the answer we must first find 18% of the 14,000 speaking how that's how much the car value diminishes in a year.
18% of 14000:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{18\times14000}{100} =18\times14000=252000\div100=2520[/tex]
[tex]=2520[/tex]
18% of 14000 is 2520, which means each year the cars value depreciates $2520 dollars.
[tex]14000-2520=11480-2520=8960-2520-6440-2520=3920-2520=1400[/tex]
[tex]=1400[/tex]
Which means it will take a "little more than 5 years" for the cars value to reach $1000.

What is the value of the function when x = 2?
Answer:
The corresponding y-value where x = 2 is -2
From the given graph, we can see that we have a straight line almost passing through the origin.
There are several points on the line expressed as a coordinate (x, y). This means that for every x-value on the x-axis, there are corresponding y values
From the line, we can see that the corresponding y-value where x = 2 is -2
Step-by-step explanation:
Answer:
-2
Similarly construct a horizontal line which goes through the point of intersection. The value of the function here at x = 2 is -2. Therefore, the value of the function is -2.Step-by-step explanation:

The measure of ∠H is 180 degrees, which is a straight angle.
What is a straight angle?An angle with a measure of exactly 180 degrees is called a straight angle. It is an angle with arms that point in opposing directions from the vertex and unites to make 180°.
The given measure of ∠H is (11x - 29).
To determine the measure of ∠H when x = 19, we can simply substitute x = 19 into the expression for the measure of ∠H:
∠H = 11x - 29
∠H = 11(19) - 29
∠H = 209 - 29
∠H = 180
Here, ∠H has a measure of 180 degrees, which is a straight angle.
Therefore, the measure of ∠H when x = 19 is 180 degrees.

Your class is having a class picture taken on the lawn. The photographer is positioned 14 feet away from the center of the class. The photographer turns 50° to look at either end of the class.
a. What is the distance between the ends of the class? Round your answer to the nearest tenth.
The distance is about
feet.
b. The photographer turns another 10° either way to see the end of the camera range. If each student needs 2 feet of space, about how many more students can fit at the end of each row? Explain. Round answers to the nearest tenth when necessary.
About
more students can fit at the end of each row. The triangle formed by the
° angle has an opposite leg that is about
feet longer than the opposite leg of the triangle formed by the
° angle. Because each student needs 2 feet of space,
more students can fit on each end with about
feet of space left over.
Answer:
a) 33.4
b) About 3 students can fit at the end of each row. The triangle formed by the 60° angle has an opposite leg of that is about 7.5 feet longer than the opposite leg formed by the 50° angle. Because each students needs 2 feet of space, 3 more students can fit on each end with about 1.5 feet of space left over.
Step-by-step explanation:
A. I used the Tangent ratio which is opposite/adjacent
tan(50)=x/14
14*tan(50)=x
*Use you calculators here and you should get about 16.68, but this is only one of the right triangle, so multiply that by 2 and you should get about 33.36 which rounded should become 33.4
B. For the amount of students you can fit at the end of each row, you need to find how long the opposite leg of the 60° triangle is than the opposite leg of the 50° triangle. to do this use the tangent ratio
since the 60° triangle is a special triangle, the opposite side is 14√3
14√3 - (14 · tan(50) ≈ 7.56 ← the answer is 7.5 probably since they didn't round (in Big Ideas)
7.56/2 ≈ 3.78 ← 2 feet of space for each student
↑answer is just 3 since you cannot split living objects
The last answer is 1.5
the get the left over amount, we would have to take the length opposite leg of the 60° triangle and divide it by the length of the opposite leg of the 50° triangle
14√3 ÷ (14 · tan(50) ≈ 1.45 ← must use parentheses otherwise they will divide your answer by 14 and then multiply, which none of us wants.

if f(x) = 2 - x^1/2 and g(x) = x^2 – 9, what is the domain of g(x) divided f(x)?
~Shoto Todoroki here~
Let's consider what we are asked. The domain is defined as a set of points that satisfy the equation on the x-ordinate.
So, essentially, we need to find if and what the restriction on x is.
Let's now consider just f(x) because g(x) is completely irrelevant to the question.
f(x) = 2 - x^(1/2)
Since f(x) can never be 0 for a defined function, let's consider when f(x) = 0 to find a restriction on x.
2 - x^(1/2) = 0
2 = x^(1/2)
+-4 = x
But we can only take the positive 4 because inside a square root has to always be positive (unless you're dealing with complex numbers), so the only restriction is that x cannot be equal to 4.
Therefore, our domain is: x >= 0; x =/= 4hope this helps :D
