s distance in kilometers. First she swam, then biked, and then she finished the race with a run. The data states she ran four times as fast as she swam and she biked twice as fast and she ran. Based on the graph, chose the statement below that is false.
A) the steeper the segment, the faster the athlete is traveling along the course

Three equivalent ratios are shown on the graph
kvasek [131]

To plot more the points, we move up one and right two.

<h3>How to plot more the points?</h3>

The ratios are given as:

(1, 0.5), (2, 1), and (5, 2.5)

Calculate the slope (m) using:

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{1 - 0.5}{2 - 1}

Evaluate

m = \frac{0.5}{1}

This gives

m = \frac{1}{2}

The above means

Vertical : Horizontal = 1 : 2

This means a vertical movement of 1, followed by an horizontal movement of 1

Hence, to plot more the points, we move up one and right two.

You’re given two side lengths of 3 centimeters and 5 centimeters. Which measurement can you use for the length of the third side
mrs_skeptik [129]

Answer:

You could use a measurement of 4 centimeters.

The valid range is  2  < x < 8  cms.

Step-by-step explanation:

The third side must either be less than 3+5, that is less than 8 cms and  it must be greater than (5-3) = 2 cms. If it is any other length we could not construct a triangle.

The quadratic x^2+7x+20$ has the same roots as the quadratic Ax^2+Bx+1 What is A+B?
sdas [7]

If f(x)=x^2+7x+20 has the same roots as g(x)=Ax^2+Bx+1, then

one must be a multiple of the other.


By comparison of the constant terms, we know that 20g(x)=f(x), or

g(x)=(1/20)f(x)

=(1/20)(x^2+7x+20)

=(1/20)x^2 + (7/20)x + 20/20

=(1/20)x^2 + (7/20)x + 1


Therefore A=(1/20), B=(7/20),  and A+B=(1+7)/20=8/20=2/5
