3 0

Answer:

60,480

Step-by-step explanation:

To find the number of ways that Paul can arrange his trophies, we can use the permutation formula.

The permutation formula is:

_{n}P_{k}=\dfrac{n!}{(n-k)!}

n = 9

k = 6

Now let's put them into the formula.

_{9}P_{6}=\dfrac{9!}{(9-6)!}

_{9}P_{6}=\dfrac{9!}{3!}

_{9}P_{6}=\dfrac{9!}{3!}

_{9}P_{6}=60,480

There are 60,480 different ways that Paul can arrange his trophies on the shelf.

A=1/2(a+b)h <br> SOLVE FOR "h"
Kamila [148]
Solving equations is a basic skill that you must master to deal with a lot of problems in mathematics, physics, chemistry, administration, economy, and almost every activity where you need to use a formula or a model. to solve for h, you follow these steps: 1) multiply both sides by 2 => 2A = (a+b)h; 2) divide both sides by (b+a) => 2A/ (a+b) = h. So the answer is: h = 2A / (a+b).

If f(x) = 5x - 2 and g(x) = 2x + 1, find (f + g)(x)
SVEN [57.7K]

Answer:

(f + g)(x) = 7x - 1

Step-by-step explanation:

Given :  f(x) = 5x – 2 and g(x) = 2x + 1

We have to find  (f + g)(x)

Consider  (f + g)(x) = f(x) + g(x)

Also, given  f(x) = 5x – 2 and g(x) = 2x + 1

Substitute, we have,

f(x) + g(x) = 5x - 2 + 2x + 1

Like Terms are terms having same variable with same degree.

Simplify by adding like terms,  we have,

f(x) + g(x) = 5x + 2x - 2  + 1

f(x) + g(x) = 7x  - 1

Thus, (f + g)(x) = 7x - 1
