Answer: 299 m/s
Step-by-step explanation:
The first step is to take the first derivative of the equation given. This will give us the equation for velocity which we will then substitute the 7 in for t.
To derive the equation you multiply the coefficient by the power of the variable, then subtract one from the variable.
v(t) = 6t^2 + 5
Now input 7 in for t to find the velocity.
v(7) = 6(7)^2 + 5
v(7) = 299 m/s
38 - 171 divided by 19 times 2
Answer:
x=5/2
Step-by-step explanation:
1. 13=6x-2 (add 2 to each side)
2.15=6x (divide each side by 6)
3.15/6=x (simplify the fraction by dividing by 3)
4.5/2=x (answer)
Answer:
8.75 miles is 70%
Step-by-step explanation:
12.5
1.25 is 10 percent
multiply that by 7
8.75 miles
The answer is
2/5 = 0.4
Because
2/5 2 divide 5 = 0.4
