What is the axis of symmetry of the graph?
×=0

y=0

x=-6

x=-3​

Let y be the total cost and x be the miles taken:

y = 0.30x + 35

35 is a fixed cost. No matter how many miles you drive the car you will still need to pay $35

.30 is a cost that depends on the miles taken (x).

Answer:

Let us assume that the pay rate per hour = x

no. of hours worked = n

Gross earnings = x*n

Federal taxes = 18% of gross earnings

= 0.18(x*n)

State taxes = 4% of gross earnings

= 0.04(x*n)

Social security deduction = 7.05% of gross earnings

= 0.0705(x*n)

Total deductions = Federal taxes + State taxes +SSD

= 0.18(x*n) + 0.04(x*n) + 0.0705(x*n)

= 0.2905(x*n)

Net pay = Gross earnings - Total Deduction

Net pay = x*n - 0.2905(x*n)

Net pay = 0.7095(x*n)

The gross earnings are $800. Deductions total $232.40, resulting in a net pay of $567.60 after federal, state taxes, and social security deductions.

Let's calculate various components of a paycheck, starting with the given pay rate and hours worked. Suppose the pay rate is $20 per hour and the employee works 40 hours per week.

1. Gross Earnings:

Gross Earnings = Pay Rate × Hours Worked

Gross Earnings = $20/hour × 40 hours

Gross Earnings = $800

2. Federal Taxes:

Federal Taxes = 18% of Gross Earnings

Federal Taxes = 0.18 × $800

Federal Taxes = $144

3. State Taxes:

State Taxes = 4% of Gross Earnings

State Taxes = 0.04 × $800

State Taxes = $32

4. Social Security Deduction:

Social Security Deduction = 7.05% of Gross Earnings

Social Security Deduction = 0.0705 × $800

Social Security Deduction = $56.40

5. Total Deductions:

Total Deductions = Federal Taxes + State Taxes + Social Security Deduction

Total Deductions = $144 + $32 + $56.40

Total Deductions = $232.40

6. Net Pay:

Net Pay = Gross Earnings - Total Deductions

Net Pay = $800 - $232.40

Net Pay = $567.60

Therefore, the gross earnings are $800, and after accounting for $232.40 in deductions for federal and state taxes along with social security, the net pay is $567.60.

Answer:

Ball Bearing Volume = (4 / 3) * PI * radius ^3

Volume = (4 / 3) * 3.14159265 * (.35)^3

Volume = (4 / 3) * 3.14159265 * 0.042875

Volume = 0.17959438 cc

1 cc of steel = 7.8 g

Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc

1 kg = 128.205 cc

Number of ball bearings we can make = 128.205 / 0.17959438

Equals 713.86

Answer:

b ≠ - 1

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the value that b cannot be.

Step-by-step explanation:

57÷27=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

57×72=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

5×77×2=3514

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 35 and 14 using

GCF(35,14) = 7

35÷714÷7=52

The fraction

52

is the same as

5÷2

Convert to a mixed number using

long division for 5 ÷ 2 = 2R1, so

52=212

Therefore:

57÷27=21/2

Answer:

A

Step-by-step explanation:

Nice problem.

The only way you can get an odd number by multiplying two digits together is if they are both odd.

For example 5*7 = 35 which is odd. You cannot find 2 odd numbers that when multiplied will give an even.

That means that A and B are both odd.

Now if you multiply an odd and an even together, you always get an even.

For example 4 * 9 = 36 which is even.

Since A is known to be odd, C must be even. So the four digit number you want ends in C.

The true statements are the third and fifth. [not sure about the second one!]

Step-by-step explanation:

1.) (7u + 4) is written as a sum of three terms.

This is false since 7u is one term, and 4  is one term, making a total of two terms, not three.

2.) 2 is a factor

I'm not sure on this but I don't think its true.

3.) In 7u, 7  is a coefficent

This is true. The coefficent is the number in front of a variable, or in this case, 7.

4.) In (7u + 4), 7u is a constant.

This is false, as a constant is a number without  any variable attached to it. The constant in this case would be 4.

5.) 8 and 1 are like terms.

This is true, since you can add 8 and 1, resulting in the sum of 9.

6.) None of these are true.

This is false, as at least 2 of these statements are true.

I hope this helps! :)

Answer:

A) 6 tan θ

Step-by-step explanation:

Given Expression:

6 sin θ sec θ

= 6 sin θ (1/cosθ)

= 6 sin θ/cos θ

= 6 tan θ

In the second step, we substituted 1/cos in place of sec because cos and sec are reciprocals of each other.

In the last step, we know used the formula:

sinθ/cosθ  =  tanθ

Answer:

A.

Step-by-step explanation:

sec(x)=1/cos(x)

So you have 6sin(x)*1/cos(x) which gives you 6*sin(x)/cos(x)

Since sin(x)/cos(x)=tan(x)

then you can rewrite this as 6tan(x)

To solve the equation (−6/11) + m = −9/2, you need to isolate the variable m. The solution to the equation is m = −33/22.

To solve the equation (−6/11) + m = −9/2, we need to isolate the variable m.

First, we can start by subtracting (−6/11) from both sides of the equation: m = −9/2 - (−6/11)

Simplify the equation by finding a common denominator: m = −9/2 + 33/11

Combine the fractions: m = −99/22 + 66/22

Finally, add the numerators and keep the common denominator: m = −33/22

Therefore, the solution to the equation is m = −33/22.

The solution to the equation is:

x = -0.8404

How to solve the equation?

The equation is given as:

[tex]\frac{3}{(x - 2)}[/tex] + 6 = √(x - 2) + 8

Subtract 8 from both sides to get:

[tex]\frac{3}{(x - 2)}[/tex] - 2 = √(x - 2)

Square both sides to get:

[tex]\frac{9}{(x - 2)^{2} }[/tex] - [tex]\frac{12}{(x - 2)}[/tex] = (x - 2)

 [tex]\frac{9 - 12(x - 2)}{(x - 2)^{2} }[/tex] = (x - 2)

Multiply both sides by (x - 2)² to get:

9 - 12x + 24 = (x - 2)³

33 - 12x = x³ - 6x² + 12x - 8

x³ - 6x² + 24x + 25 = 0

Let us try x = -0.8404 to get;

(-0.8404)³ - 6(-0.8404)² + 24(-0.8404) + 25(-0.8404) ≈ 0

Thus, - 0.8404 is a root of the polynomial.

Answer:

x = 1, y = 60

Step-by-step explanation:

Value of new-releases (x) = $20 each

Value of classic (y) = $8 each

Total budget = $500

Equation : 20x + 8y = 500

The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.

Lets assume the librarian buys at least one new-release DVD.

x=1

20x + 8y = 500

8y + 20(1) = 500

y = 60

Therefore, in a budget of $500, the librarian can purchase 60 classic movies and 1 new-release.

Step-by-step explanation:

The given function is f(x) = 9x⁻¹²

To find the inverse of f(x) we will write the function in a equation form y = 9x⁻¹²

Now we will replace x from y and y from x

x = 9y⁻¹²

Then we will find the value of y

y⁻¹² = [tex]\frac{x}{9}[/tex]

y = [tex](\frac{x}{9})[/tex]¹²

Now y will be replaced by f⁻¹(x)

f⁻¹(x) = [tex](\frac{x}{9})[/tex]¹²

Answer:

Coach Johnson will save $1.50

Step-by-step explanation:

1. The first step is to calculate the unit price for each of the packages, ie. how much a single shin guard costs.

If we look at the package of 10 shin guards for $14.50, we can calculate the unit price by dividing the package price ($14.50) by the number of shin guards (10). Thus we get:

14.50/10 = $1.45

Now, if we do the same for the package of 15 shin guards for $22.50, we get:

22.50/15 = $1.50

2. Now we can see that the lowest unit price is $1.45 (package of 10 shin guards) and the highest unit price is $1.50 (package of 15 shin guards).

3. There are two ways to see how much he would save, so I will show both here.

1) First calculate how much the coach will have to pay for a pack of 30 shin guards for each of the packages:

3 packages of 10 shin guards for $14.50 = 3*14.5 = $43.50

2 packages of 15 shin guards for $22.50 = 2*22.5 = $45.00

Now subtract the second value from the first: 45-43.5 = 1.5

Therefor, he will save $1.50.

2) The second method is perhaps what I would personally use as it is a little quicker; so we already know that the unit price for the pack of 10 is $1.45 and the unit price for the pack of 15 is $1.50 - thus, we can say that there is a difference of $0.05 per shin guard in price. Now if we were going to calculate how much the coach would save in buying 30 shin guards, we could simply multiply how much he saves on a single shin guard by 30. Thus, we get:

0.05*30 = 1.5

Therefor, again we get the same answer that Coach Johnson would save $1.50.
