Answer:
v=206ft/s , a=120ft/s
Step-by-step explanation:
We are given the equation of displacement
upon differentiating the given equation
ds/dt = 
upon substituting t = 3
v = 206ft/s
a= dv/dt
upon differentiating
dv/dt = 36t + 12
put t= 3
a=120ft/s
Should be the right answer ☺️
Answer:
Mixed fraction -2 3/8
decimal form -2.375
Improper fraction -19/8
Step-by-step explanation:
Convert the mixed numbers to improper fractions
then find the least common denminator and then combine them
so the answer is -19 / 8 or -2 3/8 as a mixed fraction
All we have to do is use the slope formula they gave us, and <u>plug in values! </u>
<u />
y2- y1
x2 - x1
8 - 2 = 6
2 - 1 = 1
So our slope is 6/1 or just 6!
Answer:
21 ft^2
Step-by-step explanation:
split area into two parts shown by the red line and add up both areas to find total area.
area = b×h/2
triangle 1 = (5×6)/2
=30/2
=15 ft^2
triangle 2 = (3×4)/2
=12/2
=6 ft^2
total area = 15+6
