Find the value of x.

Answer:

I don't know I am a babysitter too :)

Step-by-step explanation:

[tex] \tan(45) = \frac{x}{13} \\ 1 = \frac{x}{13} \\ x = 13[/tex]

[tex] \cos(45) = \frac{13}{y} \\ 2 \sqrt{2} = \frac{13}{y} \\ 2y \sqrt{2} = 13 \\ y = \frac{13}{2 \sqrt{2} } [/tex]

Answer: 1.35

Step-by-step explanation:

Answer:

1.35

Step-by-step explanation:

We need to identify our independent variables and dependent variables.

The number of papers graded depend on the amount of time.

The amount of time is the independent variable

The papers graded depends us the dependent variable

Divide the independent variable by the dependent variable to find papers per minute

For Ms.Mitchell the papers per minute is

For Mr.Rector, the papers per minute is

Subtract 2.4 from 3.75.

The answer is 1.35

Answer:

Colin will have $1,265 after three years.

Step-by-step explanation:

First, we find the amount of interest Colin will have by using the following formula,

simple interest = principal * interest rate * time

now that we know the formula, we substitute the numbers in.

simple interest = $1,100 * 5% * 3

since the interest rate is obviously a percentage, we have to convert it into a decimal.

simple interest = $1,100 * 0.05 * 3

now that it is a decimal, we can solve this expression.

simple interest = $1,100 * 0.05 * 3

simple interest = $55 * 3 (here, we did $1,100 * 0.05 first so that it doesn't get confusing with all the numbers, it will be easier with two final numbers)

simple interest = $165

Colin has $165 simple interest but over here asks how much she will have AFTER 3 years. think about it, can you have $165 after having $1,100 in your bank AFTER 3 years? no, so we need to add the interest by the principal by using the following formula,

total amount = principal + simple interest

now, we substitute the numbers in.

total amount = principal + simple interest

total amount = $1,100 + $165

total amount = $1,265  

Therefore, Colin will have $1,265 after 3 years.

Step-by-step explanation:

Answer:

Here we can not see the options, so i will answer in a general way.

When we have a function y = f(x), we define:

x as the input

y as the output.

so f(x) is some kind of "machine", in wich we put an input x, and the "machine" does something and returns an output y.

In, this case, we have:

y = f(x) = 4*x - 3

then if we give this function different inputs, we will get different ouputs.

for example, if we use the input x = 0, then the output is:

y = f(0) = 4*0 - 3 = -3

Then if we made a table for inputs and outputs, we will have the data:

[tex]\left[\begin{array}{ccc}inp&out\\x&y\\0&-3\end{array}\right][/tex]

We can rewrite this table in a general way as:

[tex]\left[\begin{array}{ccc}inp&out\\x&4*x - 3\end{array}\right][/tex]

This means that for every input x, the output is always 4*x - 3.

To complete this type of tables, we usually use different values of x, for example here I will use some different ones:

y = f(3) = 4*3 - 3 = 12 - 3 = 9

y = f(10) = 4*10 - 3 = 40 - 3 = 37

y = f(-1) = 4*-1 - 3 = -4 - 3 = -7

Then we will have a table like:

[tex]\left[\begin{array}{ccc}inp&out\\3&9\\10&37\\-1&-7\end{array}\right][/tex]

Concluding, the thing that will always represent the output of our function is: 4*x - 3.

Answer:

No

Step-by-step explanation:

The given inequality is b < 1.  We determine whether or not b = 5 is a solution by substituting 5 for b and asking ourselves whether the resultant inequality is true or not:

5 < 1 is FALSE and so b = 5 is NOT a solution of the given inequality.

Step-by-step explanation:

I'm pretty sure that it's y=5x, because it says that y represents the price, and that 2 represents that amount of board games. The price is $75, and the number of board games is 5. So the answer should be y=5x.

Answer:

1 batch

Step-by-step explanation:

Farah needs 4 and 4/5 pounds of tomatoes & and additional 5 and 3/5 pounds of tomatoes to make soup.

4.8 + 5.6 = 10.5 pounds per soup

10.5*2 = 21 > 20 pounds

Farah would need one more pound of tomatoes in order to make 2 batches of soup. Therefore she can only make 1 batch.

Step-by-step explanation:

The statement that describes the end behavior of the function f(x) = 8|x − 1| + 13 is:

As x approaches positive infinity, f(x) approaches negative infinity.C.

Let's analyze the function.

The function f(x) = 8|x − 1| + 13 involves the absolute value of x − 1, which means that the expression inside the absolute value will always be non-negative.

x approaches positive infinity, the value of x − 1 also approaches positive infinity.

Since the absolute value of a positive number is equal to the number itself, we can simplify the expression to f(x) = 8(x − 1) + 13.

As x approaches positive infinity, the term 8(x − 1) becomes larger and larger, making f(x) approach negative infinity.

The constant term 13 does not have a significant impact on the end behavior as x becomes increasingly large.
