First of all, we have

$f(x-2)=f(1) \iff x-2=1 \iff x=3$

In fact, if we choose $x=3$ , we have

$f(3-2)=f(1)$

So, let's evaluate the given function at $x=3$ :

$f(3 - 2)=f(1) = 3^3 + 3(3^2) - 3(3) +7 = 27+27-9+7=52$

Answer:

Step-by-step explanation:

f(x - 2) = f(1)

==> x -2 = 1

x = 2+1 = 3

f(x - 2) = f(3 - 2) = 3³ + 3*3² -3*3 + 7

= 27 + 27 - 9 + 7

= 54 - 2 = 52

svetlana [45]

Answer:

$2\frac{3}{4}$ pounds

Step-by-step explanation:

Maggie buys 1 1/2 pounds of walnuts, 8 ounces of pecans and 3/4 pounds of almonds.

To find the total weight of nuts that she buys, let us first put all the weights in a single unit, pounds.

She buys 8 ounces of pecans.

1 ounce = 0.0625 pounds

8 ounces = 8 * 0.0625 = 0.5 pounds = 1/2 pounds

Therefore, the total weight of nuts that she buys is:

$1\frac{1}{2} + \frac{1}{2} + \frac{3}{4}\\ \\\frac{3}{2} + \frac{1}{2} + \frac{3}{4} = 2\frac{3}{4}$

The nuts weight $2\frac{3}{4}$ pounds in all.

Explain why the amount of money in the account at the end of t years is given by the formula:

nevsk [136]

Answer:

Step-by-step explanation:

The initial amount invested is P0

Say it is compounded periodically either quarterly or monthly or semi annually with interest r%

If for a period interest is r%

Then after first period principal = principal+simple interest

= $P_{0}+\frac{P_{0}r }{n}$

where n is the no of times in a year it is compounded. n = 4 if quarterly, 12 if annually, etc

At the end of II period we have

Principal = $P_{0}+\frac{P_{0}r }{n}$

So for interest again the process is repeated

Thus we repeat this nt times which result in power with nt

Hence the formula

A basketball player shoots free throws and makes them with probability 1/7. What is the probability of the event the player will

Liula [17]

Answer:

216/343 or 0.6297 (4dp)

Step-by-step explanation:

Anytime the probability of an event occurs more than once in a particular order (one time after another in the same instance), then the probability is multiplied together. If the probability of him making the shot is 1/7, then the probability of him missing it is 6/7. This is because this is the only other possible outcomes and all outcome probabilities must add to 1 (1-1/7 - 6/7).

So, if he misses it three times in a row then the probability is:

6/7 (probability miss this first time) x 6/7 (probability miss second time) x 6/7 (probability miss 3rd time).

6/7 x 6/7 x 6/7 = 216/343

or 0.6297 (4dp)

Hope this helped!
