248 if i did my calculations correct because you already know kim traveled for 3.5 hours and got 217 miles traveled in that time so if you take 217 and divide it by 3.5 you get 62 and then you would take 62 and times it by 4 and your answer would be 248
Answer:
height = 5.682 meters
Step-by-step explanation:
height = -9.8x^2 + 7x + 3
Find the axis of symmetry: x = -b/(2a)
a = -9.8 b = 7 c = 3
x = -7/(2*-9.8) = -7/-19.6 = .357 = x = +.357 secs is when max height occurs
Find the height, replace x with .561
height = -9.8(.357^2) + 11(.357) + 3
height = -9.8(.127) + 11(.357) + 3
height = -1.245+3.927+3
height = 5.682

A slope intercept form is, take as an example: y=mx + b, because b is the number where the line intercepts the y axis.
Assuming the space inbetween -7x and 8y is a plus sign.
To get the equation in the right format, one must do the following:
8y=7x-1
y=7/8x-1/8
And theres your answer!
Note: The line intercepts the y axis in -1/8 :)
(If the space isnt a plus, i can answer diffrently in the comments.)
