Answer:
102.6666... feet in one second 1232 feet in twelve seconds.
Step-by-step explanation:
Most clear way of solving this breakdown the proportions by keep the value.
1 mile = 5280 feet.
1 hour = 60 minutes = 3600 seconds -- See now it is easy.
Feet per second...
= feet/seconds
(70*5280) = 369,600/3,600 = 102.666666667 -- That is 102.66...feet per second.
For twelve seconds just multiply by 12.
102.666666667*12 = 1232 feet in twelve seconds.
Answer:
upward
Step-by-step explanation:
it's opens upward because a (the invisible 1 in front of x^2) is positive
A. First, find the slope, which is -0.5, and then insert it into point-slope form, which is y-y1=m(x-x1), or y-1=-0.5(x+5). That's point-slope form.
B. First, distribute -0.5 to both terms in the parenthesis, to get y-1=-0.5x-2.5, and lastly add 1 to both sides to get the slope-intercept form of y=-0.5x-1.5
