Hope this helps:)
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
Given:
y = 2x + 6
x - the number of miles between restaurant and point of delivery
y - the number of minutes between the time an order is place and the time it is delivered.
The correct conclusion is:
<span>C) It takes the restaurant about 6 minutes to prepare each order for delivery
2x is the time it takes to deliver the order, every mile is traveled within 2 minutes.
6 is the number of minutes it takes to prepare the order before it will be set out for delivery.

D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.
For #1, C. 1080, For #2, B. 7, For #10, I think its because of the reflexive property (honestly, Google it just to be safe) , And for #11, A Rhombus, Having trouble remembering why but I know its not a rectangle or square.
