Answer:
100 revolitions
Step-by-step explanation:
180s = 3min
50s = 1min
50 * 2 = 100
Answer:
Or, 1/2.
Step-by-step explanation:
To find the slope of a line that crosses any two given points, we can use the slope formula:
Where (x₁, y₁) is our first point, and (x₂, y₂) is our second point.
We will let (6, -7) be our first point (x₁, y₁), and (4, -8) be our second point (x₂, y₂).
Substitute them into the formula. Hence:
Simplify:
Evaluate. Hence, our slope is:
Answer:
The common difference of the progression is 3.
Step-by-step explanation:
Given:
First term of the AP = (a) = -8
Ratio of 7th and 9th term = 5:8
So,
General term of an AP, Tn= a+(n-1)d
Where 'd' is the common difference.
equation...(i)
equation...(ii)
According to the question.
⇒ ...cross-multiplying the terms.
⇒
⇒
⇒ ...subtracting 40d and adding 64 both sides.
⇒
⇒ ...dividing both sides with 3.
So the common difference of the progression is 'd' = 3.
