Answer:
15 seconds
Step-by-step explanation:
Put the given heights in the equation and solve for t.
h(t) = -16t² +3600
0 = -16t² +3600 . . . . h(t) = 0 at ground level
16t² = 3600 . . . . . . . add 16t²
t² = 3600/16 = (60/4)² = 15² . . . . . divide by 16
t = 15 . . . . . . . . . . . . take the square root
It will take 15 seconds for the phone to hit the ground.
Answer:
Therefore the angle that the line through the given pair of points makes with the positive direction of the x-axis is 45°.
Step-by-step explanation:
Given:
Let
A(x₁ , y₁) = (1 , 4) and
B( x₂ , y₂ ) = (-1 , 2)
To Find:
θ = ?
Solution:
Slope of a line when two points are given is given bt
Substituting the values we get
Also Slope of line when angle ' θ ' is given as
Substituting Slope = 1 we get
We Know That for angle 45°,
tan 45 = 1
Therefore
Therefore the angle that the line through the given pair of points makes with the positive direction of the x-axis is 45°.
The probability that the spinner will land on c at least once is 5/9
<h3>How to determine the probability?</h3>
From the complete question, the probability that the spinner will not land on c when spun twice is:
P = 4/9
Using the complement rule, the probability that the spinner will land on c at least once is:
P' = 1 - P
This gives
P' = 1 - 4/9
Evaluate
P' = 5/9
Hence, the probability that the spinner will land on c at least once is 5/9
