If that number is x:
120 = 1.60x
x = 120/1.60=75
3.10
I think, Im very sorry if this is wrong!
Answer is provided in the image attached.
Answer:
16pi cm2
Step-by-step explanation:
Area of a circle = pi * radius * radius = pi * 4 cm * 4 cm = 16pi cm2
Answer:
Equation: 5t² − 10t + 13 = 0
Answer: No
Step-by-step explanation:
h(t) = -5t² + 10t + 22
When h(t) = 35:
35 = -5t² + 10t + 22
5t² − 10t + 13 = 0
This equation must have at least one real solution if the ball is to reach a height of 35 meters. Which means the discriminant can't be negative.
b² − 4ac
(-10)² − 4(5)(13)
100 − 260
-160
The ball does not reach a height of 35 meters.
