Answer:

y=(1/4)x+3

step-by-step explanation:

the equation that ur asking for is called slope intercept formula

slope intercept formula needs the two points and the intercept and the slope, so we have the points, but we need to find the slope and intercept

point 1: (0,3)

points 2: (4,4)

slope: y2-y1/x2-x1

4-3/4-0 = slope

slope=1/4

now to find the formula u need to replace the variable for the known value, so uk the two points and the slope

slope intercept formula is y=mx+b

m=slope = 1/4

b= intercept

replace the slope y=(1/4)x+b

then u need the intercept, for that u need to pick a point, any point from the line and replace the Y and X

4=(1/4)4+b

now solve for B

multiply 1/4 and 4 which is 1

4=1+b

then subtract one to both sides 4-1=1-1+b

3=b

now replace B to the formula and u have y=(1/4)x+3

A business uses straight-line depreciation to determine the value y of an automobile over a 5-year period. Suppose the original

Elena-2011 [213]

For this problem. it is found that:

a) The automobile has depreciated 75% in 5 years.

b) The value of the automobile was reduced by $10,500 in five years.

c) The linear function is: s(t) = 14,500 - 2,100t.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = ax + b

In which:

a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

From the problem, we have that:

a) The automobile has depreciated 75% in 5 years, as 4000/14500 = 0.25, and 100% - 25% = 75%.

b) The value of the automobile was reduced by $10,500 in five years, as 14500 - 4000 = $10,500.

For the linear function, we have that:

The initial value is b = 14500.

The slope is of a = -10500/5 = -2100.

Hence the linear function is: s(t) = 14,500 - 2,100t.

A regular pentagon has an apothem of 7.3 inches and a perimeter of 53 inches. What is the area of the pentagon? Round your answe

zvonat [6]

Answer:

Area pf the regular pentagon is 193 $inch^{2}$ to the nearest whole number

Step-by-step explanation:

In this question, we are tasked with calculating the area of a regular pentagon, given the apothem and the perimeter

Mathematically, the area of a regular pentagon given the apothem and the perimeter can be calculated using the formula below;

Area of regular pentagon = 1/2 × apothem × perimeter

From the question, we can identify that the value of the apothem is 7.3 inches, while the value of the perimeter is 53 inches

We plug these values into the equation above to get;

Area = 1/2 × 7.3× 53 = 386.9/2 = 193.45 which is 193 $inch^{2}$ to the nearest whole number
