Answer:

Step-by-step explanation:

We have 9 choices for Choosing the first object

8 choices for Choosing the 2nd object

3 choices for Choosing the seventh object

Therefore if we want to choose7 objects without replacement from 9 objects we have : 9×8×7×6×5×4×3 = 181 440

Also ,we can calculate it this way :

9P7 = 181 440

You invest $600 in an account that has a annual interest rate of 7%, compounded quarterly for four years. What is the equivalent

alexandr402 [8]

Answer:

equivalent rate: 7.186%
compounded 16 times

Step-by-step explanation:

The equivalent interest rate is the rate that would have to be applied so it would earn the same amount in 1 year. It is computed from ...

requiv = (1 +r/n)^n -1

requiv = (1 +0.07/4)^4 -1 ≈ 7.186%

"Compounded quarterly" means interest is compounded 4 times per year. In 4 years, it will be compounded 4·4 = 16 times.

The balance in the account after 4 years is ...

$600·(1 +.07/4)^(4·4) ≈ $791.96

For what values of x is x2 2x = 24 true? Ă˘â‚¬""6 and Ă˘â‚¬""4 Ă˘â‚¬""4 and 6 4 and Ă˘â‚¬""6 6 and 4.

The value of $x$ which satisfies the given quadratic equation is 4 and -6.

Given-

The given quadratic equation is.

$x^2+2x=24$

Rewrite the given quadratic equation in the standard form,

$x^2+2x-24=0$

Factorize the equation to find the value of $x$ . Apply the middle term splitting method. The above equation can be rewritten as,

$x^2+6x-4x-24=0$

$x(x+6)-4(x+6)=0$

$(x-4)(x+6)=0$

$x=4,-6$

Hence, the value of $x$ which satisfies the given quadratic equation is 4 and -6.
