Beth claims that the value 7 × 106 written below is the largest value because it has the greatest multiplier. James claims that the value 3.2 × 107 written below is the largest because it has the greatest power of ten. Ariel claims that the value 4.02 × 105 written below is the largest value because it has the multiplier with the most place values. Who is correct?

Answers

Answer: Beth is correct

Step-by-step explanation:

Answer:
Beth is correct

First let’s multiply each of the values

Beth:
106 x 7 = 742

James:
107 x 3.2 = 335

Ariel:
105 x 4.02 = 630

Therefore Beth is correct as the highest value is 742.

The following points represent a relation where x represents the independent variable and y represents the dependent variable.

three fourths comma negative 2, 1 comma 5, negative 2 comma negative 7, 1 comma negative one half, and 6 comma 6

Does the relation represent a function? Explain.

Answers

Answer:

the 4th answer is correct

Step-by-step explanation:

No, the relation doesn't represent a function because for each output there is not exactly one input.

What is a function?

In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables, one is an independent variable and the other is the dependent variable.

We have been given a relation in which x represents the independent variable and y represents the dependent variable.

This relation isn't a function because, for input, there are two different outputs which are -2 and -1/2.

Hence, the third option, C; No because for each output there is not exactly one input, is the correct answer.

Sky High TV is a satellite television provider. They charged about a month. The first month of service costs 85.45. After the second month, the total cost is $148.65. After the third month, the total cost is $211.85. An equation in the form of y = c + d(x - 1) to represent the situation. Define the variables. ____________________________________________________________________________________________________________________________________________________________________________________________________________

Answers

Answer: y = 63.20x + 22.25, where x is the number of months and y is the total cost.

Step-by-step explanation:

Let's start by finding the value of the constant term c. We know that the first month of service costs $85.45, so we have:

y = c + d(x – 1)

85.45 = c + d(1 – 1)

85.45 = c

Now we need to find the value of the slope d. We can use the information from the second and third months:

y = c + d(x – 1)

148.65 = 85.45 + d(2 – 1)

63.20 = d

y = c + d(x – 1)

211.85 = 85.45 + d(3 – 1)

126.40 = 2d

Simplifying the second equation, we get:

63.20 = d

Substituting the values of c and d into the equation, we get:

y = 85.45 + 63.20(x – 1)

y = 63.20x + 22.25

Therefore, the equation that represents this situation is:

y = 63.20x + 22.25, where x is the number of months and y is the total cost.

You know that some percent of a number is 45.

a) How much is the same percent of twice that number?

b) How much is the same percent of half that number?

Answers

Percentage(%) is a fraction with 100 in the denominators place. So, when you say 45% of a number, that means you are dividing the number into 100 small parts and taking 45 parts from them.

Suppose, you want 45% of a number ‘x' (say). That means you divide the number into 100 small parts. So x100
x
100
is the small part we got. Now, we have to take 45 parts from them, so we multiply the small part by 45 , thus getting 45x100
45
x

.

If you want to get the 45% of a number, just multiply it with 45100
