Answer:

7098

Step-by-step explanation:

j = 21

k = 8

j x [(k² x 5) + 18]

21 x [(8² x 5) + 18]

21 x [(64 x 5) + 18]

21 x [320 + 18]

21 x 338

Phan earned gross wages of $487.12. Phan's deductions were: $49 in federal withholding taxes, 6.2% in social security taxes, 1.4

iren [92.7K]

Answer:

$360.12

Step-by-step explanation:

Phan's net pay would be equal to the gross wage he receives minus the deductions:

Gross wage= $487.12

Federal withholding taxes= $49

Social security taxes= $487.12*6.2%= $30.2

Medicare taxes= $487.12*1.45%= $7.06

Health insurance= $28.74

Union dues= $12

Net pay= $487.12-$49-$30.2-$7.06-$28.74-$12

Net pay= $360.12

According to this, Phan's net pay is $360.12.

Answer:

The maximum revenue will be $R=\$25,000$ at price $p=\$100.$

Step-by-step explanation:

Given:

$R=-2.5p^2+500p$

Find the vertex of the parabola represented by given equation:

$p_v=\dfrac{-b}{2a}=\dfrac{-500}{2\cdot (-2.5)}=\dfrac{500}{5}=100$

When $p=\$100,$ then

$R=-2.5\cdot 100^2+500\cdot 100=-2.5\cdot 10,000+50,000=-25,000+50,000=25,000$

The maximum revenue will be $R=\$25,000$ at price $p=\$100.$

For the following right triangle, find the size length X. Round your answer to the nearest hundredth

Vlad1618 [11]

Answer:

The answer would be 10.72

Step-by-step

You already have two side lengths so you use those to find the 3rd length

$A^{2}$ + $B^{2}=C^{2}$

$A^{2}+9^{2} =14^{2}$

$A+81=196$

196-81=115

$\sqrt{115$
