The table shows the distance Allison drove on one day of her vacation. Is the relationship between the distance and the time a p
Anuta_ua [19.1K]

Answer:

we conclude that the relationship between distance and time is NOT proportional.

Hence, she did not drive at a constant speed.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get the equation

y ∝ x

y = kx

k = y/x

where 'k' is called the constant of proportionality.

In our case, the table shows the distance Allison drove on one day of her vacation.

Time (h)              1         2        3          4        5

Distance (mi)       55    100     165     280    250

using the equation

k = y/x

susbtitute y = 55, x = 1

k = 55/1 = 55

substitute y = 100, x = 2

k = y/x

k = 100 / 2 = 50

substitute y = 165, x = 3

k = y/x

k = 165 / 3 = 55

substitute y = 280, x = 4

k = y/x

k = 280 / 4 = 70

substitute y = 250, x = 5

k = y/x

k = 250 / 5 = 50

It is clear that the value of 'k' does not remain constant.

Therefore, we conclude that the relationship between distance and time is NOT proportional.

Hence, she did not drive at a constant speed.

Help I will be marking brainliest!!!!
artcher [175]

Answer: <em>A. 241 feet</em>

Step-by-step explanation:

<em>The figure shows two rectangular triangles. </em>

<em>These triangles are similar since they have two identical angles: </em>

<em>the first angle is 90 degrees; </em>

<em>the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection. </em>

<em>The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.</em>

<em>Let's make the proportion:</em>

<em />\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\<em />

<em>It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:</em>

<em>341.25 - 100 = 241.25 (feet)</em>

<em>241.25 ≈ 241 (feet)</em>
