Answer: 8
Step-by-step explanation:
We can use trigonometry to solve this:
If we call the angle at the top Ф then x is the opposite and 8 is the adjacent
Therefore we use Tan to solve this:
Tan Ф = opposite/adjacent
Tan 45 = X/8
1 = X/8
8 x 1 = X
Therefore X = 8
Answer:
10 meters.
Step-by-step explanation:
We know the ball travelled a distance of at least 6 meters as that is how far it was dropped.
It rebounded 2/3 of 6 meters, which is 4 meters.
6 meters add 4 meters is 10 meters.
Answer:
y = -0.07x2 + 3.07x
Step-by-step explanation:
For each plant we add, there is a decrease of 70 grams for all plants from the inicial value of 3 kg of beans.
So, for 2 plants, we have (3 - 0.07) * 2
For 3 plants, we have (3 - 2*0.07) * 3
For x plants, we have (3 - (x-1)*0.07) * x
So we can model the final result of the amount of beans 'y' with the equation:
y = (3 - (x-1)*0.07) * x
y = (3 - 0.07x + 0.07) * x
y = (3.07 - 0.07x) * x
y = -0.07x2 + 3.07x
(In this equation we have a = -0.07, b = 3.07 and c = 0)
