The entrance to an accessibility ramp is at ground level.

The first section of the ramp covers a horizontal distance of 18 feet and rises to a landing 1.5 feet above the ground.

The second section of the ramp begins at the landing. It rises at a slope of \frac{1}{18}
and covers another 9 feet of horizontal distance to reach the door.

NOTE: Sketch not drawn to scale.

Answer the questions to compare the sections of the ramp.

1. What is the slope of the ramp from the ground to the landing? Write your answer as a fraction with a whole-number numerator and denominator.

Answers

Answer:

Step-by-step explanation:

slope = "rise over run" = 1.5/18 = 3/36 = 1/12 for the 1st section to the landing

slope is the change in height, the vertical change, divided by the change in horizontal distance

2nd section has slope 1/18 and covers 9 feet. That means it rises 1/2 foot

slope = 1/18 = (1/2)/9

the door is 2 feet higher than the ground level, 1.5 + .5 = 2 feet change vertically

Jennifer’s bank account is modeled by the following equation where x equals the number of weeks and
f(x) equals the total balance.
f(x) = 12x + 45
william's bank account balances after weekly deposits are showing in the following table.
Jennifer claims that her bank account is growing at a greater rate of change than William’s bank account. Is Jennifer correct? Justify your reasoning.

Answers

Jennifer is incorrect, her bank account is growing at a rate of 12x, and Williams bank account is growing at 14x. Jennifer just started out with more money.
NO JENNIFER IS NOT CORRECT

Jennifer is correct her bank account is growing at a greater rate of change than William’s bank account. Because, initially Jennifer has $45 in her account and it grows every week.

Given that, Jennifer’s bank account is modeled by the equation f(x)=12x+45.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Substitute x=0, 1, 2, 3, 4, we get y=12x+45

Now,

When x=0, y=12(0)+45=45

When x=1, y=12(1)+45=57

When x=2, y=12(2)+45=69

When x=3, y=12(3)+45=81

When x=4, y=12(4)+45=103

Jennifer is correct her bank account is growing at a greater rate of change than William’s bank account. Because, initially Jennifer has $45 in her account and it grows every week.

The length of one side of the square is the square root of its area. Use the table to find the approximate length of one side of the square. Explain how you used the table to find this information.

The length of the track is 377.6 feet

What is the area of the square?

The area of the square is defined as the product of the length and width.

Given that area of the square is 128 square feet.

The sides can be found by taking the square root of the area.

The area of the square = s², where s = side.

⇒ s =√(Area)

⇒ s = √(128) = 11.3

So the length of one side of the square is 11.3 feet.

Since the circumference of a circle = πD

Here D = 11.3 feet.

So circumference of a circle = π(11.3) = 355 feet

The length of the track = 2(11.3)+ 355 = 377.6

Thus, the length of the track is 377.6 feet
