Answer:
11:22 AM
Step-by-step explanation:
By means of a statement we can know that:
After an hour and 8 minutes, he stays 8 minutes behind
Which means that in 2 hours, it will take 16 minutes
If it is 10:30, it means that it is 6:30 hours later, that is to say 6.5.
therefore 6.5 x 8 = 52
Which means that at 10:30 the clock is 52 minutes late
So the correct time is 11:22 AM
Answer:
<h3>5 seccs</h3>
Step-by-step explanation:
Given the modeled function of the height expressed as;
h(t)=-16t^2+64t+80
The ball hits the ground when h(t) = 0 (when the height is zero)
Substitute into the function and find t;
0 =-16t^2+64t+80
divide through by -16
0 = t²-4t-5
Factorize;
t²-4t-5 = 0
t²-5t+t-5 = 0
t(t-5)+1(t-5) = 0
(t+1)(t-5) = 0
t + 1 = 0 and t-5 = 0
t = -1 and t = 5
Time can't be negative
Hence it will take the ball 5secs before it hits the ground
To find the x, let's look at the sketch below:
All we simply need to do is to use Pythagorars theorem to find y
x is a radius and y is also a radius
Hence x and y are congruent
So Using Pythagoras theorem
y² = 3.6² + 4²
y² = 12.96 + 16
y² = 28.96
Take the square root of both-side of the equation
y ≈ 5.4
Therefore, x= 5.4
The X coordinate changes when you translate a figure left.
