Answer:
Step-by-step explanation:
<u>Instantaneous Velocity</u>
Given r(t) as the vector function of the position for time t, the instantaneous velocity is computed as:
We are given:
Thus:
Computing the derivative:
Evaluating for t=π/4:
Square root of 6 times 16 will give us 39.19
The square root of 48 times 32 [which gives us 1536] is also equal to 39.19
The square root of 1536 is equal to 39.19
Hence, x is equal to 32
Hope this helped! :D
<span>Well 68/80 as a percent is 85 % .I got that by dividing 68 by 80 and them multiplying by 100. 100-85= 15. So therefore the dress decreased in price by 15%. </span>
Answer:
176.7 square feet
Step-by-step explanation:
Diameter, d = 15 feet
radius, r = d/2
r = 15/2 = 7.5 feet
π = 3.142
Area of the pool = area of a circle
= πr^2
= 3.142 * 7.5^2
= 176.7375
to the nearest tenth
= 176.7 square feet
