Answer:

Either B or C but i'll have to say B if I had to choose.

Step-by-step explanation:

${0.9}^{0} = 1$

${0.9}^{1} = 0.9$

$0.9 ^{2} = 0.81$

${0.9}^{3} = 0.729$

${0.9}^{4} = 0.6561$

${0.9}^{5 } = 0.59049$

As we can tell it decreases slowly.

Verizon [17]

Answer:

$6:2,\,9:3$

Step-by-step explanation:

Given: The ratio of cups of sparkling water to cups of grape juice concentrate is $3:1$ in a recipe for fizzy grape juice.

To find: two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe

Solution:

Equivalent ratios are the ratios that have the same value.

Find two ratios equivalent to $3:1=\frac{3}{1}$

Multiply both numerator and denominator of $\frac{3}{1}$ by 2

$\frac{3(2)}{1(2)} =\frac{6}{2}$

Multiply both numerator and denominator of $\frac{3}{1}$ by 3

$\frac{3(3)}{1(3)} =\frac{9}{3}$

So, two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe are $6:2,\,9:3$

Answer:

Gross monthly income:$1,125

Monthly Federal income tax (11.6%): $130.50

Monthly Social security (FICA) (6.2%): $69.75

Monthly Medicare (1.45%): $16.3125

Monthly State Tax (4%): $45

Monthly Local Tax (0.1%): $1.125

Total Monthly deductions $262.6875

Trey’s NMI $862.3125

Explanation:

Calculation for What is his monthly taxes

First step is to calculate the Gross monthly income

Using this formula

Gross monthly income=Annual salary/Numbers of months in a year

Let plug in the formula

Gross monthly income=$13,500/12 months

Gross monthly income=$1,125

Therefore the Gross monthly income is :$1,125

Monthly Federal income tax (11.6%): $130.50

($1,125*11.6%)

Monthly Social security (FICA) (6.2%): $69.75

($1,125*6.2%)

Monthly Medicare (1.45%): $16.3125

($1,125*1.45%)

Monthly State Tax (4%): $45

($1,125*4%)

Monthly Local Tax (0.1%): $1.125

($1,125*0.1%)

Total Monthly deductions $262.6875

($130.50+$69.75+$16.3125+$45+$1.125)

Trey’s NMI $862.3125

Trey’s NMI=Gross monthly income-Total Monthly deductions

Trey’s NMI=$1,125-$262.6875

Trey’s NMI=$862.3125

Therefore his monthly taxes are:

Gross monthly income:$1,125

Monthly Federal income tax (11.6%): $130.50

Monthly Social security (FICA) (6.2%): $69.75

Monthly Medicare (1.45%): $16.3125

Monthly State Tax (4%): $45

Monthly Local Tax (0.1%): $1.125

Total Monthly deductions $262.6875

Trey’s NMI $862.3125

Can anyone help with either one of these

Vlada [557]

slope-point form:
we need the slope (m) and a point.
y-y₀=m(x-x₀)
Given two point A(x₁,y₂) and B(x₂,y₂), the slope of the line is :
m=(y₂-y₁) /(x₂-x₁)

Example 3:
we can take two points:
A(12,2)
B(13,7)
m=(7-2) / (13-12)=5/1=5

therefore:
y-2=5(x-12)
y-2=5x-60
y=5x-60+2
y=5x-58

answer: y=5x-58

Example 4:
we can take two points.
A(0,0)
B(3,1)
m=(1-0)/(3-0)=1/3

Therefore:
y-0=1/3(x-0)
y=x/3

answer: y=x/3

Given f(x) = x^2 – 3 and g(x) = x+2/x . Find (g ° f)(4).

Gnom [1K]

Answer:

Step-by-step explanation:

Given the two functions, we need to find

(g ° f)(4)

This means, we need to put the function f(x) INTO the function g(x) and then evaluate that new function at x = 4.

We put the whole expression of f(x) into "x" of g(x). Shown below:

$f(x)=x^2-3\\g(x)=\frac{x+2}{x}\\(gof)(x)=\frac{x^2-3+2}{x^2-3}\\(gof)(x)=\frac{x^2-1}{x^2-3}$

Now we plug in 4 into x and evaluate:

$(gof)(x)=\frac{x^2-1}{x^2-3}\\(gof)(4)=\frac{4^2-1}{4^2-3}\\(gof)(4)=\frac{15}{13}$

Thus,

correct answer is C
