Given f(x) = 17-x^2, what is the average rate of change in f(x) over the interval [1, 5]

1 answer:

3 0

Average rate of change over [1,5] = f(5) - f(1) / 5 - 1

= [(17-5^2) - (17-1) ] / 4

= (-8 - 16) / 4 = -24 / 4 = -6 Answer

There are 16 possible outcomes.

Step-by-step explanation:

For this question, we combine the possibilities together.

R = red G = green O = orange B = blue

There are 16 possible outcomes.

You can also find the total number of possible outcomes by using the formula for permutations. n is the total number of choices. r is the number you are examining.

$\frac{n!}{(n-r)!}$

$\frac{4!}{(4-2)!} =12$

This number doesn't include the outcome of having the same color twice. There are four colors meaning that their four outcomes in which the same color is spun twice.

12 + 4 = 16

Signal mistakenly produced 1,000 defective cell phones. the phones cost $60 each to produce. a salvage company will buy the defe

zhannawk [14.2K]

We are asked to solve for the incremental net income from reworking the phones.
Number of items = 1000
Production Cost = 1000*$60 = $60,000
Salvage value = 1000*$30 = $30,000
Rework Cost = 1000 *80 = $80,000
Price when resold = 1000 * $120 = $120,000

Incremental Net = $120,000 + $30,000 - $60,000 -$80,000
Incremental Net = $10,000

The answer is $10,000.

Someone pllss help me

Answer:

I= 1,600

B= 9,600

Step-by-step explanation:

Interest is 8,000 x 0.04(4%) x 5

when you multiply all three (PRT) you end up with 1,600 as your interest.

then your balance is when you add the original borrowed amount ($8,000) with your interest ($1,600).

8,000+1,600= 9,600
