Answer:

They travelled the same distance and they spent the same amount of time from the 225 marker to 230 marker.

Step-by-step explanation:

Given

See attachment for graph

Required

The relationship between distance and time travelled by Kevin and Carrie

The straight line represents Kevin's journey while the curve represents Carrie's

From the graph, we can see that the straight line and the curve both start at the origin (0,0) and they both end at the same point (17,5)

Point (17, 5) represents the 230 marker (i.e. 225 + 5 - 230)

<em>Since the line and the curve meet at this point, then they travelled the same distance and they spent the same amount of time.</em>

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $135 for 100 minutes of us
LenKa [72]
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6

The ordered pairs are: (100, 135) and (500, 375)

The first number is the number of minutes of usage and the second number is the charge of the month.

The slope is: ( 375 -135) / (500 - 100) = 240/400 = 0.6

If someone could please help me, I want to make sure that the steps are correct.
Leya [2.2K]
Your answer would be the last option, c = √(E/m).

We can see this when we rearrange the equation, as:

E = mc²
÷ m
E/m = c²
√
√(E/m) = c

So you got all the steps in rearranging correct :)


I hope this helps!

Carlos bought a $235 water heater with his credit card. He used the water heater for five years before replacing it. He paid off
Mazyrski [523]

First we will find the interest on:


P = $235 principal


t = 2 years


r = 0.1415 annual rate


A = future value 


I = A - P the interest


A = P(1 + r)^t


A = 235(1 + 0.1415)^2


A = $306.21


I = A - P


I = $306.21 - $235


I = $71.21


the interest was $71.21.



Next lets find the lifetime cost value:


Lifetime cost value = 306.21 + 5*1.56*52 + 5*0.78*52 = $914.61 (considering that 1 year = 52 weeks)



Now lets find the percentage what percentage the interest is of the lifetime cost:


(71.21/914.61)*100 = 7.79%
