The electric usage for a computer repair company was charted over four months. What is the rate of change for the bill during that time? KWH used Billing 578 $109.82 1,033 $196.27 1,475 $280.25 1,754 $333.26 A. $0.56 per KWH B. $1.79 per KWH C. $0.19 per KWH
Answer:
The correct option is;
C. $0.19 per KWH
Step-by-step explanation:
The given data are;
KWH [tex]{}[/tex] Billing
578 [tex]{}[/tex] $109.82
1,033 [tex]{}[/tex] $196.27
1,475 [tex]{}[/tex] $280.25
1,754 [tex]{}[/tex] $333.26
Therefore, we have the rate of change, m, given as follows;
m =(Change in the amount paid)/(Change in the electric usage in the same period)
For the first and second month, the rate of change is therefore;
m = ($196.27 - $109.82)/(1,033 - 578) = $0.19 per kWH
Between the first and third month, the rate of change is given as follows;
m = ($280.25 - $109.82)/(1,475 - 578) = $0.19 per kWH
Between the first and fourth month, the rate of change is given as follows;
m = ($333.26 - $109.82)/(1,754 - 578) = $0.19 per kWH
Therefore;
The rate of change is constant and is $0.19 per kWH

Use a calculator to find the approximate value of the expression. Round the answer to two decimal places.
The cosine of the complimentary angle to 38°
a. 0.68
b. -0.16
C. -0.22
d. 0.62
Answer:
The cosine of the complementary angle to 38° is 0.62. Answer: d
Explanation:
Complementary Angle
Two angles x and y are complementary if
x+y=90°
The complementary angle of 38° is 90°-38°= 52°
Now use a calculator to find the approximate value of
[tex]\cos 52^\circ \approx 0.61566[/tex]
Rounding to two decimal places:
[tex]\cos 52^\circ \approx 0.62[/tex]
a. Incorrect. The cosine of 52° is not 0.68
b. Incorrect. The cosine of 52° is not -0.16
c. Incorrect. The cosine of 52° is not -0.22
d. Correct. The cosine of 52° is 0.62 to two decimal places.

Which type of function best models the data in the table?
O exponential
O logarithmic
O linear
O quadratic
Answer:
c.) linear
Step-by-step explanation:
just took the quiz
The function represented in the table is a linear function given by y = (1/4)x + 80
What is an equation?An equation is an expression that shows the relationship between two or more number and variables.
Let y represent the pressure of the gas at x temperature.
Using the point (44, 91) and (52, 93), hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-91=\frac{93-91}{52-44} (x-44)\\\\y=\frac{1}{4} x+80[/tex]
The function represented in the table is a linear function given by y = (1/4)x + 80

If y = 12 when x = –15, find y when x = 2.
Answer:
29
Step-by-step explanation:
First make an equation that shows the relationship between x and y by finding what you need to do to x to get y:
-15 + ? = 12
? = 27
so the equation is : y = x + 27
now just plug in 2 for x:
y = 2 + 27
y + 29

Ken and Donna are driving from Baltimore, MD to Richmond, VA for a wedding. The total distance they must drive is 131 miles. Since the reception is late, they decided to get a bite to eat along the way. They want the first part of the trip to be 65 miles more than the second part. How many miles will they drive before they stop?
Answer:
The distance they drive before they stop is 98 miles.
Step-by-step explanation:
Since Ken and Donna are supposed to drive a total distance of 131 miles from Baltimore, MD to Richmond, VA for the wedding. If the first part of the journey is supposed to be 65 miles more than the second part. Let the second part be x miles. So, the first part is x + 65 miles
Since the total distance covered is 131 miles,
x + x + 65 = 131
adding the x's, we have
2x + 65 = 131
subtracting 65 from both sides, we have
2x = 131 - 65
2x = 66
dividing both sides by 2, we have
x = 66/2
x = 33 miles.
So, for the first part the distance travelled is x + 65 miles, so, x + 65 = 33 + 65 = 98 miles. So, the distance they drive before they stop is 98 miles.
