Hello,

To solve this, we should first write an inequality.
Since we have to pay $109.50 to rent the studio, we will start with that.
Then, we add on 15 per person. Finally, it needs to be under $319.

The inequality is:
109.5 + 15x < 318

Solve it gives:
15x < 208.5
x < 13.9

We have to invite less than 13.9 people. So they most we can invite is only 13.

I hope this helps,
MrEQ

What is the mathematical induction of 1+3+5+...+(2n-1)=n^2

Lena [83]

Let $S(n)$ be the statement that

$1+3+5+\cdots+(2n-1)=\displaystyle\sum_{k=1}^n(2k-1)=n^2$

Check to see that $S(n)$ holds for $n=1$ :

$\displaystyle\sum_{k=1}^1(2k-1)=1=1^2\implies S(1)\text{ is true}$

Now suppose that $S(N)$ is true, and use that assumption to show that $S(N+1)$ must also be true. When $n=N+1$ , you have

$\displaystyle\sum_{k=1}^{N+1}(2k-1)=\sum_{k=1}^N(2k-1)+2(N+1)-1$
$=N^2+2(N+1)-1$
$=N^2+2N+1$
$=(N+1)^2$

and so $S(N+1)$ is also true, thus proving the statement is true for all $n$ .

An account earns simple annual interest. You deposit $600 into an account at 5% interest rate for 2 years. (a) Find the interest

Ilia_Sergeevich [38]

Answer:

(a) $60 | (b) $660

Step-by-step explanation:

We can use the simple interest formula for this:

$I=Prt$

I = interest amount

P = principal amount

r = interest rate (decimal form)

t = time (years)

First, change 5% into its decimal form:

5% -> $\frac{5}{100}$ -> 0.05

Next, plug in the values into the equation:

$I=600(0.05)(2)$

$I=60$

The interest earned is $60. To find the total balance, just add the $600 back.

$600+60=660$

The total interest earned is $60 and the total is $660.

Hey there :)

f (x) = 5x² - 2x
g (x) = 3x² + x - 4

( f + g )( x ) is f ( x ) + g ( x )

5x² - 2x + 3x² + x - 4
Combine like-terms
5x² + 3x² - 2x + x - 4
8x² - x - 4

Your option will be the third option
