Answer:

g(3)= 8

g(-6)= 35

Step-by-step explanation:

g(3) = $3^{2}$ -1

g(3) = 9 - 1

g(3) = 8

g(-6) = $-6^{2}$ -1

g(-6) = 36 - 1

g(-6) = 35

The length of a rectangle is 1 ft less than twice the width, the area of the rectangle is 21 ft squared. What’s the length

guapka [62]

Answer:

The length of the rectangle is 6 feet

Step-by-step explanation:

Given as :

The length of rectangle is 1 feet less than twice the width

So, let The width of rectangle = w feet

The length of rectangle = ( 2 w - 1 ) feet

The area of the rectangle = 21 feet²

Now,

∵ The area of the rectangle = length × width

Or, 21 feet² = ( 2 w - 1 ) feet × w feet

or, 21 = 2 w² - w

or, 2 w² - w - 21 = 0

or, 2 w² + 6 w - 7 w - 21 = 0

or , 2 w ( w + 3 ) - 7 ( w + 3 ) = 0

or, ( w + 3 ) ( 2 w - 7 ) = 0

So, w = - 3 feet , $\frac{7}{2}$ feet

here we consider only positive value of w i.e $\frac{7}{2}$ feet

∴ The length of rectangle = ( 2 w - 1 ) feet

or, The length of rectangle = 2 × $\frac{7}{2}$ - 1

Or, The length of rectangle = 7 - 1 = 6 feet

Hence The length of the rectangle is 6 feet , Answer

Most people know that social security and medicare taxes are deducted from their paychecks. As a new restaurant owner, you learn

vredina [299]

Answer:

The yearly payroll will cost the employer $538,250.

Step-by-step explanation:

a) Data and Calculations:

Budgeted payroll = $500,000

Social security tax rate = 6.25%

Medicare tax rate = 1.4%

Social security tax = $31,250 ($500,000 * 6.25%)

Medicare tax amount= $7,000 ($500,000 * 1.4%)

Total taxes amount = $38,250

The total yearly payroll cost should be put at $538,250 ($500,000 + 38,250). This means that as the employees pay taxes amounting to $38,20, the employer will also pay matching taxes amounting to $38,250.
