4. Suppose your car has a maximum straight-line braking acceleration of 5.0 ms 2. Calculate the stopping distance for the following initial speeds: (a) 24.6 ms (~55 mph), (b) 31.3 ms (~70 mph), and
(c) 38 m s [~85 mph). (d) How is stopping distance related to your initial speed? (e) What effect does
doubling your speed have on stopping distance? (f) Suppose you increase your speed by 15%, what is
the percent increase of your stopping distance?

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
