What is the power of 15 ------------------

Mathematics
1 answer:
miv72 [106K]3 years ago
4 0

Answer:

If something is "to the power of 15" then it means it is multiplied by itself 14 times (one less than 15 as the original number is already to the power of 1).

An example:

So 2 to the power of 15, which we write as 215 = 2 * 2 * 2 * 2 etc... (so we have 15 written 2's in total meaning we will make 14 multiplications) is equal to 32,768.

2) f(x) = x² **<br> g(x)= 3x – 2<br> Find f(g(-4)
Usimov [2.4K]

Answer:

f(g( - 4)) = 196

Step-by-step explanation:

The functions are;

f(x) =  {x}^{2}

and

g(x) = 3x - 2

We want to find

f(g( - 4))

First we find g(-4) to get:

g( - 4) = 3 \times  - 4 - 2

g( - 4) =  - 12- 2

g( - 4) =  - 14

Now

f(g( - 4)) = f( - 14)

This implies that,

f(g( - 4)) = {( - 14)}^{2}

f(g( - 4)) = {( - 14)} \times  - 14

f(g( - 4)) = 196

Nicholas wants to buy a new computer that is on sale for $899. His parents will loan him the money if he repays them. He has $22
Afina-wow [57]

Answer:

20 days

Step-by-step explanation:

899- 225= 674

674÷ 35= 19.257....

which you would round it up to 20 because he would have to work the extra day because you need more than less.

John is buying food for his cat, Fluffy. Fluffy LOVES a fancy wet food which costs $1.50 per day. Fluffy will also tolerate dry
Vedmedyk [2.9K]

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.

Hence:

x + y = 7                    (1)

Also, John wants to spend at most $9.00 on cat food each week. Hence:

1.5x + 0.75y ≤ 9       (2)

The list of possible points after solving graphically are:

(0,7), (6,0), (0,12) and (5, 2). If x,y > 0, then the point that satisfies the inequality is:

(5, 2) i.e. 5 wet food and 2 dry food

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
Mashcka [7]

Multiplying eqn no. two with 4 we add it up with eqn 1.

4x - 5y = 10 \\  - 4x - 12y = 32 \\

- 17y = 42 \\ y =  \frac{ - 42}{17}

When

- x - 8 = 3y \\ x + 3y =  - 8

x =  - 8 -  3 \frac{ - 42}{17 }  \\ x =  - 8 +  \frac{42}{17}  \\ x =   \frac{ - 10}{17}

So, x = - 10/17 and y = - 42/17.
