Answer:

If a is 1.. we substitute one in every a in g(a)

4 * 1 + 16

4+ 16 = 20

g(a)= 20

f(20)

-16 + 20 = 4

and 4/4 = 1

so f (g (a)) = a

Sergeeva-Olga [200]

Answer:

hello your question is incomplete below is the complete question

Patrice Matson works for a company that uses a percentage method to compute income tax withheld. Patrice is single and claims two allowances. Each allowance is $63.46 each week. She earns $480 per week. Find the amount of income tax withheld.

answer: $35.3

using the percentage method The percentage of Patrice  income to be withheld as tax based on his weekly income  = 10% of taxable income

Gross income per week = $480

Allowances = $63.46 * 2 = $126.92

Taxable income = $480 - $126.92 = $353.08

amount to be withheld as tax = 10.% * $353.08 = $35.3

bezimeni [28]

Answer:

  about 0.177 mg/mL

Step-by-step explanation:

The maximum is found where the derivative of C(t) is zero.

  dC/dt = 1.35e^(-2.802t) -(1.35t)2.802e^(-2.802t) = 0

Solving for t gives ...

  t = 1/2.802

So, the maximum C(t) is ...

  C(1/2.802) = 1.35/2.802e^(-1) ≈ 0.177 . . . . . mg/mL

The maximum average BAC during the first 6 hours is about 0.177 mg/mL.

_____

The maximum occurs about 21 minutes 25 seconds after consumption.

The ellipse with x-intercepts (2, 0) and (-2, 0); y-intercepts (0, 4) and (0, -4).
masya89 [10]

Answer:

\dfrac{x^2}{4}+\dfrac{y^2}{16}=1

Step-by-step explanation:

If the ellipse has its x-intercepts at points (2, 0) and (-2, 0) and y-intercepts at points (0, 4) and (0, -4), then its symmetric across the y-axis and across the x-axis.

Moreover,

a=2\\ \\b=4

The equation of such ellipse is

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1

Hence, the equation of the ellipse is

\dfrac{x^2}{2^2}+\dfrac{y^2}{4^2}=1\\ \\ \\\dfrac{x^2}{4}+\dfrac{y^2}{16}=1

11x is 11 times the number.  You are to take 6 less than this. Be careful how you read six less. It means the 6 is subtracted from the 11x

11x - 6 This is what you finally get.
