Answer:

274560

Step-by-step explanation:

We can "choose" one of the 66 athletes for the gold medal. That athlete can't win any other medals, so there are 65 athletes left.

We can then "choose" one of the 65 athletes left for the silver medal. That athlete can't win any other medals, so there are 64 athletes left.

We can then "choose" one of the 64 athletes left for the bronze medal.

That leaves us with 66 possible choices * 65 possible choices * 64 possible choices=274560 possible choices

If B equals 7 what is the value of the expression 2 + (10 - B )?

avanturin [10]

We just need to plug in 7 for B!

Let's do it !

2 + (10 - 7)

We always start with the parenthesis first ! It's just a rule in math :)

10 - 7 = ?

10 - 7 = 3

Now we have ...

2 + 3

2 + 3 = 5

Your final answer is 5!

I hope I helped :) Just comment if you have any questions and remember to vote me "brainliest" if you like my answer !!!

St Question 1 Calculate the derivative of y = f(x) = 3 x(4x + 7) Your answer:

kondor19780726 [428]

Answer:

$\frac{dy}{dx} = 24 x + 21$

Step-by-step explanation:

Explanation:-

Given that the function

y = f(x) = 3 x ( 4 x + 7)

y = 3 x ( 4 x + 7)

y = 12 x² + 21 x ..(i)

Differentiating equation (i) with respective to 'x' , we get

$\frac{dy}{dx} = 12 (2x) +21 (1)$

$\frac{dy}{dx} = 24 x + 21$

Mary Stahley invested $2500 in a 36-month certifi- cate of deposit (CD) that earned 8.5% annual simple interest. When the CD mat

Answer:

$13,916.24

Step-by-step explanation:

First, we need to find the value of the CD at maturity.

A = P(1 +rt) . . . . simple interest rate r for t years

A = $2500(1 +0.085·3) = $2500×1.255 = $3137.50

Now, we can find the value of the account with compound interest.

A = P(1 +r)^t . . . . . rate r compounded annually for t years

A = $3137.50 × 1.18^9 = $13,916.24

The mutual fund was worth $13,916.24 after 9 years.
