Answer:
velocity at t=1 is 1 ft/s
Step-by-step explanation:
by integration s(t) equation we get v(t)
v(t)=33-32t
by substitution t=1 in v(t) equation we get
33-32=1 ft/s
Answer:
C
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinC = 
= 
= 
, thus
∠ C = 
( ) ≈ 34.85° ( to 2 dec. places )
C - 0.15c is the same as 1c - 0.15c.
1 - 0.15 = 0.85.
Joe can also use 0.85c.
Answer: 333.33m²
Step-by-step explanation:
Since we are informed that 15 litres of paint covers an area of 250 m2, the the area that 1 liter of paint will cover will be:
= 250m²/15
= 16.666667m²
Therefore, the area that 20 litres of paint will cover will be:
= 16.666667m² × 20
= 333.33m²
