Answer:

We conclude that the person is saving $60 dollars per week.

Hence, option C is true.                        

Step-by-step explanation:

Given the table chart

Week                   Saving Money

2                           60

4                           120

6                           180

8                           240

We know to determine the slope to find the rate of change.

Taking the points (2, 60) and (4, 120)

Rate of change = Slope =  [y₂ - y₁] / [x₂ - x₁]

                                        = [120 - 60] / [4 - 2]

                                        = 60 / 2

                                        = $30 dollars per week

Now, taking the points (4, 120) and (6, 180)

Rate of change = Slope =  [180 - 120] / [6 - 4]

                                        = [60] / [2]

                                        = $30 dollars per week

Now, taking the points (6, 180) and (8, 240)

Rate of change = Slope =  [240 - 180] / [8 - 6]

                                        = [60] / [2]

                                        = $30 dollars per week        

  • This concludes that the rate of change is contant i.e. $30 dollars per week

Therefore, we conclude that the person is saving $60 dollars per week.

Hence, option C is true.

in a right triangle the acute angles measure x+15 and 2x degrees what is the measure of the larger acute angle of the triangle
Akimi4 [234]

<span>So, x+15 + 2x = 90 </span><span>
<span>Therefore 3x = 90 - 15 = 75 </span>
<span>and so x=25. </span>

<span>So the smaller angles are x+15 = 40 degrees and 2x=50 degrees. </span>
<span>So the larger one is 50 degrees.</span></span>

Mira's gross pay is $1846.
Effectus [21]

Answer:

Total FICA tax deducted from gross pay is $ 141 .22 .

Step-by-step explanation:

As given

Mira's gross pay is $1846.  


The Social Security tax is 6.2% of gross pay.

6.2% is written in the decimal form.

= \frac{6.2}{100}

= 0.062

Social Security tax = 0.062 × Gross pay

                               = 0.062 × 1846

                               = $ 114.452

As given

The Medicare tax is 1.45% of gross pay.

1.45% is written in the decimal form .

= \frac{1.45}{100}

= 0.0145

Medicure tax = 0.0145 × Gross pay

                      = 0.0145 × 1846

                      = $ 26.767

Total FICA tax deducted from Gross pay = Social Security tax + Medicure tax

                                                                    = $114.452+ $26.767

                                                                    = $141.219

                                                                    = $141.22 (Approx)

Therefore the total FICA tax deducted from gross pay is $ 141 .22 .

Answer for this it’s to hard for me
Ilia_Sergeevich [38]

Answer:

Option A

Step-by-step explanation:

From the graph given in the picture,

Function 1

Rate of change = Slope of the line

Slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is,

Slope = \frac{y_2-y_1}{x_2-x_1}

Therefore, slope of the given line which is passing through (1, 2) and (-1, -2)will be,

Rate of change = \frac{2+2}{1+1} = 2

Function 2

Equation of the line is,

y = \frac{1}{2}x+7

By comparing this equation with slope-intercept form of the equation,

y = mx + b

Here m = rate of change Or slope of the linear function  

Rate of change of function 2 = \frac{1}{2}

Therefore, rate of change of function 1 is higher than function 2.

Option A will be the answer.
