The length of a room is 2 1/2 feet more than its width. If the perimeter of the room is 80 feet, find its width and length?

Answers

Answer:

The width is 20.625 and the length is 19.375

Step-by-step explanation:

Let 2 1/2 + w = length

Let w = width

Equation:

2 1/2 + w + w = 80 Combine liked terms

2 1/2 + 2w = 80

-2 1/2 -2 1/2 Subtract 2 1/2 from both sides

2w = 77.5

÷ 2 ÷ 2 Divide 2 from both sides

w = 41.25

Length:

2 1/2 + 41.25 = 165/4 or 38.75

Width:

41.25

41.25/2 = 20.625

38.75/2 = 19.375

Write a linear function f with f(5)=7 and F(-2)=0.

Answers

Answer:

f(x)=x+2

Step-by-step explanation:

Slope= (7-0)/(5-(-2)) = 7/7 = 1

Y-intercept= 2

substitute the slope, 1, for m and the y-intercept, 2, for b to get:

f(x)=x+2

hope this helps!

The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2

f(5) = 7

This means when x = 5 , y = 7

(5, 7)

f(-2) = 0

(-2, 0)

This implies when x = -2 , y = 0

Using the linear function formula,

y = mx + b

where

m = slope

b = y-intercept

Therefore, the function can be represented as follows:

m = 0 - 7 / -2 - 5 = -7 / -7 = 1

Therefore,

y = x + b

0 = -2 + b

b = 2

The function in relation to x can be represented as follows:

f(x) = x + 2

The elevator of a building is currently 10 feet above ground level on the first floor. The building's elevator rises at a rate of 5 feet per second. You enter the elevator on the first floor. Let t, represent the number of seconds you are in the elevator and h(t) represent the height of the elevator (in feet). Write an equation for h(t) b. What will your height be in 12 seconds? c. What does h(5) = 35 represent?

Answers

Answer:

[tex]h(t) = 10 + 5t[/tex]

70 feet

Your height in 5 seconds is 35 feet

Step-by-step explanation:

From the question, we understand that:

[tex]Initial\ Height = 10[/tex]

[tex]Rate = 5[/tex] per second

Solving (a): Equation for h(t)

This implies that the height at t seconds and is calculated as thus:

[tex]h(t) = Initial\ Height + Rate * t[/tex]

Where t represents seconds

Substitute values for Initial Height and Rate

[tex]h(t) = 10 + 5* t[/tex]

[tex]h(t) = 10 + 5t[/tex]

Solving (b): Height in 12 seconds

This implies that:

[tex]t = 12[/tex]

Substitute 12 for t in [tex]h(t) = 10 + 5t[/tex]

[tex]h(12) = 10 + 5 * 12[/tex]

[tex]h(12) = 10 + 60[/tex]

[tex]h(12) = 70[/tex]

Hence, your height will be 70 feet

Solving (c): h(5) = 35 means?

Using the illustration in (b) above;

This means that your height in 5 seconds is 35 feet

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.

y = 3x −24y = 3x −24

y = 3x + 24

y = -3x + 24

y = -3x - 24

Answers

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

In triangle DEF, segment DJ is a perpendicular bisector of side EF. If EJ is 3y-8 and JF is 7y-40, what is the length of JF?

Answers

Answer: The length of JF = 16 units.

Step-by-step explanation:

Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.

i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]

If EJ is 3y-8 and JF is 7y-40.

Then, [tex]3y-8=7y-40[/tex]

[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]

JF= 7(8)-40 =56-40= 16 units

Hence, the length of JF = 16 units.
