Answer: -$480
Step-by-step explanation:
The revenue us P*x
now, when P = $40, we have:
X = 14400 - 3*40^2 = 9600
then the revenue is:
9600*$40 = $384000
now, the price increaces by $2 so the new equation is:
X = 14400 - 3*42^2 = 9108
The revenue is:
9109*$42 = $382536
You can see that the revenua is smaller than before.
Now, if we want to calculate the rate of change when p = $40, we need to look at X'(40)
this is:
X´(p) = -3*2*p
then:
X'(40) = -3*2*40 = -120
Theh rate of change of the revenua will be:
X'(40)*$40 = -120*$40 = -$480
The person is traveling 30 mph.
The car is traveling 45 mph.
Just mulitply 15 x 3 and 10 x 3.
Let’s break the numbers down.
10 + 5 = 15. So we can break 15 down like how you add 15.
10 x 3 = 30.
5 x 3 = 15.
Let’s add 30 and 15 together.
30 + 15 = 45.
Let’s now multiply 10 and 3.
10 x 3 = 30.
I hope this helped!
Answer:
i would say A
Step-by-step explanation:
Answer:
a = 1
Step-by-step explanation:
First, you subtract 6 from both sides and you end up with a² = 1. Since one cannot be squared or square rooted, a = 1. I hope this helps!
