Answer:
Step-by-step explanation:
We can describe it as a linear function with points of:
Slope intercept formula:
Finding the slope using the two given points:
Finding b:
Formula obtained:
For x = 20, value of y is:
To express the cost, y, as a linear function of the number of heaters, X, we can use the two-point formula to find the equation of the line. The equation is y = 260x + 700, and the cost to produce 20 heaters is $5900.
To express the cost, y, as a linear function of the number of heaters, x, we need to find the slope and y-intercept of the equation. We can do this by finding the equation of the line that passes through the points (5, 2000) and (15, 4600). Using the two-point formula, we have:
slope = (4600 - 2000) / (15 - 5) = 2600 / 10 = 260
y-intercept = 2000 - 260 * 5 = 2000 - 1300 = 700
Therefore, the equation of the line is y = 260x + 700.
To find the cost to produce 20 heaters, we substitute x = 20 into the equation:
y = 260 * 20 + 700 = 5200 + 700 = 5900
So, the cost to produce 20 heaters is $5900.

Jeremy's data set shows ____ skew.
B) C = 1.25w + 12.50
C) C = –1.25w + 12.50
D) C = –1.25w – 12.50
For this case we have a function of the form:
Where,
We have then that Avery has a total of $ 12.50 in her piggy bank at home:
Each week she takes out $ 1.25 to ride the city bus:
Substituting values we have:
Answer:
an equation representing the balance, C, in the piggy bank, where w is the number of weeks is:
Option C
Answer : 50 degree
To find angle 1 , we apply outside angle theorem . Refer to the diagram attached below.
Measurement of arc EF=140 degrees
Measurement of arc GH = 40
Angle D = angle 1
Theorem says
Now we plug in the values
angle 1 = 50
Measurement of angle 1 = 50 degrees
Answer:
800 inches³
Step-by-step explanation:
∵ The volume of each cube is s³
∵ The length of the side is 2 inches
∴ The volume of the cube = 2³ = 8 inches³
∵ The prism consists of 100 cubes
∴ The volume of the prism = 100 × 8 = 800 inches³
Another method:
We divide the number of cubes to form the rectangular prism
5 cubes as a length , 2 cubes as a width and 10 cubes as height
∵ The length of the side of each cube is 2 inches
∴ The length = 5 × 2 = 10 inches
∴ The width = 2 × 2 = 4 inches
∴ The height = 10 × 2 = 20 inches
∵ The volume of the prism = L × W × H
∴ V = 10 × 4 × 20 = 800 inches³
