The formula for acceleration is (∆v)/(∆t), or (final velocity - initial velocity)/(final time - initial time). If you input your values the problem would work out as followed:
A = <span>(∆v)/(∆t)
A = (25-9)/(8-5)
A = 16/3
A = 21.33 (rounded to the nearest hundredth)</span>
Answer:
f(5)=11 and f(6)=14
Step-by-step explanation:
Answer:
-1 1/4
Step-by-step explanation:
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
5/4 = 1 1/4
Answer:
The value of the expression is - 9.
Evaluating the expression before simplifying is preferred because you only have to substitute once instead of substituting three times.
Step-by-step explanation:
x = 2
- 8x + 5 - 2x - 4 + 5x
= - 8x - 2x + 5x + 5 - 4
= - 10x + 5x + 1
= - 5x + 1
= - 5 ( 2 ) + 1
= - 10 + 1
= - 9
