Your answer is 84 meters.
We can call the width x, and thus the length 5x, and then we can say that 5x × x = 245, which simplifies to 5x² = 245, and then we can solve:
5x² = 245
÷ 5
x² = 49
√
x = 7
Now that we know what x is, we can find the perimeter by using it as the width, and then multiplying it by 5 to find its length. This gives us:
(7 × 2) + (5 × 7 × 2) = 14 + (35 × 2) = 14 + 70 = 84
So your answer is 84 meters.
I hope this helps!
The answer is 2/3 because 3/8x16/9= 2/3
The period of y = cot x is kπ where k∈<span>Z.</span>
Answer:
at 2/3 seconds
Step-by-step explanation:
S1(t) = t³ + 2
Average speed, dS1/dt = 3t²
S2(t) = t²
Average speed, dS2/dt = 2t
The distance between the objects is
dS1/dt - dS2/dt
= 3t² - 2t
The time the distance between the two object is at minimum is when the distance is 0
That is, when
3t² - 2t = 0
t(3t - 2) = 0
t = 0 or 3t - 2 = 0
t = 0 or t = 2/3
