Answer:
4.0 seconds
Step-by-step explanation:
The equation for ballistic motion is ...
y = -4.9t^2 +22.1t
We want to find the larger value of t that makes y = 10.
10 = -4.9t^2 +22.1t
4.9t^2 -22.1t +10 = 0
Using the quadratic formula, we have ...
t = (22.1 + √(22.1² -4(4.9)(10)))/(2·4.9) = (22.1 +√292.41)/9.8 = 39.2/9.8
t = 4
The ball was in the air 4 seconds before it got stuck.
Step-by-step explanation:
1. a) q=4+0.8(7)
q=4+5.6
q=9.6
b) q=4+0.8(100)
q=4+80
q= 84
2. a) 12=4+0.8p
-4 -4
<u>8</u>=<u>0.8p</u>
0.8 0.8
10=p
b) 60=4+0.8p
-4 -4
<u>56</u>=<u>0.8p</u>
0.8 0.8
70=p
Answer:
The answer is (5, 2)
Step-by-step explanation:
I. If move left = -x
move right = +x
So -2 - 3 = -5 => move left
-5 + 10 = 5 => move right
I suggest that move left and right is x cordinate
The answer is (5,2)
Is that correct?
Answer:
These are parallel lines. Which means they're (Inconsistent)
