Given
d(t) = 0.8t ^2
t= 5 secs
d(5) = 0.8(5)^2 = 0.8 * 25 = 20
t= 10 secs
d(10) = 0.8(10)^2 = 0.8 * 100 = 80
20 m / 5 secs = 4 meters per sec
80 m / 10 sec = 8 meters per sec
4 mps + 8 mps = 12 mps
12 mps / 2 = 6 mps
6 mps is the average speed of the rock between 5 and 10 sec after being dropped
Answer:
35x³-25x4y³/5x²y² = −5x6y5+35x3
Answer:
0.034522 (for decimal)
Step-by-step explanation:
Answer: 12.6 + b = 15.7
Step-by-step explanation:
Here a be the length of equal sides of the isosceles triangle and b be the length of the base of the triangle,
And, the given equation that model the given situation is,
2 a + b = 15.7
Since, a = 6.3,
By putting this value in the above equation,
We get,
2 × 6.3 + b = 15.7
⇒ 12.6 + b = 15.7
Which is the required equation that will use to find the base of the triangle.
