When the graph rises one square for a run of one square, the slope is 2 km/(0.5 h) = 4 km/h. When the graph rises half that fast, the slope is 2 km/h. When the graph is horizontal, the slope is 0. The slope of the distance vs time curve is the speed.

S = 4 km/h, when 0 < t < 2 h
S = 0, when 2 h ≤ t < 2.5 h
S = 4 km/h, when 2.5 h ≤ t < 3 h
S = 0, when 3h ≤ t < 4 h
S = 2 km/h, when 4 h ≤ t < 5 h

24. Daniel bought a new car for $15,000. He also paid two fees for the car dealership: • $450 for an extended warranty • $275 fo

Vikki [24]

The amount of down payment is $1368.08.

We add the fees to the price of the vehicle:
15000+450+275 = 15725.

We take 100% of this number and add an additional 8.75% sales tax; 100+8.75 = 108.75; 108.75% = 108.75/100 = 1.0875:
1.0875(15725) = 17100.94

He paid 8% of this total as a down payment; 8% = 8/100 = 0.08:
17100.94*0.08 = 1368.08

Challenge Yael used to have a square garage with 370 ft ^2of floor space. She recently built an

Yuki888 [10]

Scale factor of area is the square of the scale factor of length

The required values are;

The length of one sides of the garage was originally approximately 19.2 ft.

The length of one of the sides of the garage is now approximately 23.6 feet long

The percentage increase in length is approximately 22.5 %

Reason:

The given parameters are;

The area of the square garage = 370 ft.²

The area of the new garage has 50% more space

Required;

Part A

The initial side length

The initial side length, given to the nearest tenth, s, is the square root of the area, A, given as follows;

s = √(370 ft.²) ≈ 19.2 ft.

Part B

The side was increased by 50%, to give,

370 + 0.5×370 = 555

The new area of the garage = 555 ft.²

The side length of the new garage, s = √(555) ≈ 23.6

The side of the garage now is 23.6 ft.

Part C

The percentage increase is given as follows;

$The \ percentage \ increase \ in \ length = \dfrac{New \ length - Initial \ length}{Initial \ length }$

$The \ percentage \ increase \ in \ length = \dfrac{\sqrt{555} - \sqrt{370} }{\sqrt{370} } \times 100 \approx 22.5 \%$

The percentage increase in length of the side of the garage is approximately 22.5 %

Which of the following tables represents a function? A. *|- 11 -5 -4 1

tekilochka [14]

Answer: Option A

Step-by-step explanation:

A relation between two variables x and y is considered a function if and only if, for each input value x there is only one output value y.

If for an input value $x_0$ there are two output values $y_1$ and $y_2$ then the relation is not a function.

Therefore, to answer this question, identify the table in which each value of x has only one value of y.

You may notice that the option that meets this requirement is option A

Note that in option B, there are two output values 17 and 16 for x = -4.

So this relationship is not a function.

In option C there are 2 output values for x = -5

In option D there are 2 output values for x = -11
