Answer:

You can use the Pythagorean theorem

Step-by-step explanation:

The equation is a^2+b^2=c^2

(the ^ thing indicates an exponent here)

Say you have a right triangle with one side being 5cm, and another being 12cm, you can plug those two values into the equation as such

5^2+12^2=c^2

then you solve

5 to the second power is 25, and 12 to the second power is 144. put those two in and you got

25+144=c^2

add the two

169=c^2

Once you get there, you take the square root of 169(nice) which would get you 13.

And that right there, would be your answer to this problem.

Hope this helps! The equation can go either way too.

You can arrange it like b^2+c^2=a^2 or c^2+a^2=b^2 or whatever you want.

Answer:

5 years and 5 months

Step-by-step explanation:

<u>Compound Interest Formula</u>

$\large \text{$ \sf A=P(1+\frac{r}{n})^{nt} $}$

where:

A = final amount
P = principal amount
r = interest rate (in decimal form)
n = number of times interest applied per time period
t = number of time periods elapsed

Given:

A = $17,474.00
P = $7,790.00
r = 15% = 0.15
n = 12
t = number of years

Substitute the given values into the formula and solve for t:

$\implies \sf 17474=7790\left(1+\dfrac{0.15}{12}\right)^{12t}$

$\implies \sf \dfrac{17474}{7790}=\left(1.0125}\right)^{12t}$

$\implies \sf \ln\left(\dfrac{17474}{7790}\right)=\ln \left(1.0125}\right)^{12t}$

$\implies \sf \ln\left(\dfrac{17474}{7790}\right)=12t \ln \left(1.0125}\right)$

$\implies \sf t=\dfrac{\ln\left(\frac{17474}{7790}\right)}{12 \ln \left(1.0125}\right)}$

$\implies \sf t=5.419413037...\:years$

Therefore, the money was in the account for 5 years and 5 months (to the nearest month).

You would end up having $12,000 at that rate since 54 divided by 9 is 6

How do you do this?PLZ HELP

Alisiya [41]

3(x^2+10x+5)-5(x-k)=
3x^2+30x+15-5x+5k=
3x^2+25x+15+5k

for this to be divisible by x every term must include x or get eliminated

the problematic terms are 15 and 5k
to eliminate them they must equal 0 when added:
15+5k=0
5k=-15
k=-3

so A) -3 is the solution
