Answer:
-1/5
Step-by-step explanation:
When a line is perpendicular to another line, it's gradient will be a reciprocal.
To calculate the reciprocal of a number you have to flip the fraction the other way around.
So, in the case our current gradient is 5/1 (5/1 is the same as just 5) and we need to flip in over to get 1/5, which is our new gradient.
The final step is to make the number negative because the line is going down. This gives us the final answer of -1/5.
50 is a composite number. 50 = 1 x 50; 2 x 25; or 5 x 10. Factors of 50: 1, 2, 5, 10, 25, 50.
Prime factorization: 50 = 2 x 5 x 5.
<span>8.4. To come to this conclusion, one must remember that 1/10 of a number is in essence saying this is 1 out of 10 equally divided portions of a number. This is equivalent to 10%. Multiply the number by the denominator, in this case 10, and you will get the total number.
0.84 x 10 = 8.4 (10% x 10 = 100%). Another way to look at it is to add 0.84 ten times. Either way you should end up with 8.4.</span>
Answer:
v0 + 1/2at
Step-by-step explanation: Given that the distance a race car travels is given by the equation d = v0t+12at2 where v0 is the initial speed of the race car, a is the acceleration, and t is the time travelled.
The equation for the driver's average speed s during the acceleration will be:
(v0t+12at2) / t
Since Average speed is equal to distance divided by time.
Therefore, the equation will be:
v0+1/2at
