Nolan deposited $2300 into a savings account for which interest is compound weekly at a rate of 2.12%.

Shkiper50 [21]

p(1+r/n)^(r times n)

P is your start amount

R is rate as a decimal 5% would be 0.05

t is time (years)

n is the number of time compounded , weekly would be 52 times a year.

2300(1 + (0.0212/52))^(52 times 7)

2300(1.0004076)^(364)

Valentina's family is planning to have a party for her quinceanera. They are considering two different locations to rent for her

CaHeK987 [17]

Answer:

number of hours = 3 hours

Step-by-step explanation:

Let

x = number of hours

Casa Lucia = 200 + 500x

Silver Fox = 1,100 + 200x

To solve the equation, equate both cost of rent

Casa Lucia = Silver Fox

200 + 500x = 1,100 + 200x

200 - 1,100 = 200x - 500x

-900 = - 300x

x = -900 / -300

x = 3 hours

number of hours = 3 hours

The solution to the system of equations in this real-world context represents the number of hours both locations can be rented with the same cost.

It means both locations cost the same if rented for 3 hours each

Find all x-intercepts and y-intercepts of the graph of the function . f(x) = - x ^ 3 + x ^ 2 + 12x If there is more than one ans

ololo11 [35]

Answer:

The y-intercept is (0,0)

The x-intercepts are (-3,0), (0,0), and (4,0)

Step-by-step explanation:

So we have the function:

$f(x)=-x^3+x^2+12x$

And we want to solve for the x- and y-intercepts.

To solve for the y-intercept, recall that the y-intercept is when the graph touches the y-axis. At that point, the x values is 0. Thus, to find the x-intercept, substitute 0 for x:

$f(x)=-(0)^3+(0)^2+12(0)$

Simplify:

$f(x)=0$

So, the y-intercept is (0,0)

To solve for the x-intercept(s), set the function equal to 0 and solve for x:

$0=-x^3+x^2+12x$

First, factor out a negative x:

$0=-x(x^2-x-12)$

Factor within the parentheses:

$0=-x(x-4)(x+3)$

Zero Product Property:

$-x=0\text{ or } x-4=0\text{ or } x+3=0$

Divide by -1 on the first one. Add 4 on the second one. And subtract 3 on the right:

$x=0\text{ or } x=4\text{ or } x=-3$

So, our x-intercepts are:

$(-3,0), (0,0), (4,0)$

And we're done :)

If the Math Olympiad Club consists of 13 students, how many different teams of 5 students can be formed for competitions?

rjkz [21]

Answer:

2 teams

Step-by-step explanation:

13 divided by 5 is 2.6, but you cannot split a person in half, so it would be two teams with a remainder of three people.
