Answer:-5/7,-4/7,-3/7,-2/7
Step-by-step explanation:
I didn't round by the answer would be 115.575042 miles per second.
The question can't be solved because we can't have negative sign under square root
Answer:
The car is going up at a speed of 22.5 mph
Step-by-step explanation:
In this question, we are asked to calculate the speed of a moving car which started moving at an initial velocity for a specific period of time.
To calculate this, we use one of the basic equations of motion;
v = u + at
Where v is the final velocity, u is the initial velocity and t is the time
From the question, we can identify the parameters as follows;
v = ?
u = 10mph
a = 2.5t mph per second for 5 seconds.
Hence a here would be 2.5 * 5 = 12.5
Now, let’s put these values in the equation
v = 10 + 12.5
v = 22.5 mph
So the equation here is
95*(1+x) = 109.25
solve for x
1+x = (109.25/95)
x = (109.25/95) -1
x = .15 or 15%
