The <em>average</em> rate of change doesn't require calculus.
It's just
           
         (amount of change during some time) / (amount of time for the change) .

You need calculus when you want the <em>instantaneous</em> rate of change . . .
that's the rate of change at a single point in time.

X2+11x+30 what does x2 mean
Alexxandr [17]

x^2 in the function that you typed is x * x ( x multiplied by x). It represents a second degree because there are only 2 "x"s multiplied together. If there were 3 "x"s multiplied together, we would have x^3. Since the highest exponent in this function is 2 (in x^2), we call this function a 2nd degree polynomial.

Find the values of x work 10% of my grade
Ostrovityanka [42]

Answer:

x = 35

Step-by-step explanation:

1. Add all angles

115+(x+36)+24+(2x+10)+2x

= 5x+185

2. Match 360 and fix

5x+185=360

5x=360-185

5x=175

x=175/5

x=35

Hope this helps

Noah manages a buffet at a local restaurant. He charges $10 for the buffet. On average, 16 customers choose the buffet as their
kicyunya [14]

Answer:

$3 max

Step-by-step explanation:

Charge= b, Customer= c, Revenue= r

r= bc, currently, r= 16*10= $160

We know that: b+1 ⇒ c-2  and the target is r ≥ 130

So, this will all be reflected as:

b=10+x ⇒ c= 16-2x

  • (10+x)(16-2x) ≥ 130
  • 160 -20x +16x - 2x² ≥ 130
  • -2x² - 4x + 30 ≥ 0
  • x² + 2x -15 ≤ 0
  • (x+1)² ≤ 4²
  • x+1 ≤ 4 (negative value not considered)
  • x ≤ 3

As we see the max increase amount is $3, when the revenue will be:

(10+3)*(16-3*2)= 13*10= $130
