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
Answer:
C
5(10)+10=60
-2(-5)+7=17
Step-by-step explanation:
Step-by-step explanation:
14×5=70
8×8=64
(3/70) + (5/64)
= (3×64)+(5×70)
----‐------------------
70×64
= (192+350)/448
=542/448
= 271/224
Answer:
cost = 8p + 5
Step-by-step explanation:
$8*[number of pizzas] + $5 delivery fee
$8p + $5
8p + 5
cost = 8p + 5
