Answer:
<h2>10.3seconds</h2>
Step-by-step explanation:
Step one:
given data
acceleration,a= 10ft/sec^2
final velocity v= 70mph
first, let is convert mph to ft/sec
1mph is 1.46667 ft/sec
70 mph is x
cross multiply we have
x= 102.7ft/s
Step two:
we are using the first equation of motion
v=u+at
initial velocity u= 0m/s
102.7=0+10*t
102.7=10t
divide both sides by 10
t=10.3seconds
Answer:
4
Step-by-step explanation:
<u>Step 1: Set j to 25 and k to 5</u>
j/k - 0.2k
(25)/(5) - 0.2(5)
5 - 1

Answer: 4
Answer:
the answer should be C.
Step-by-step explanation:
When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle. A right angle is represented by the symbol ∟.
First, get it into slope-intercept:
y = -3/5x + 4/5
The slope is -3/5
