Item 9 Find the annual interest rate. I=$562.50, P=$1500, t=5 yearsI=$562.50, P=$1500, t=5 years The annual interest rate is %.

Anton [14]

Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%

Hope it helps:-)

Yes. I think so. Even if there is not intercept the intercept is 0

2. If x is directly proportional to y^3 and x=32 when y=2, i) Find an equation

svp [43]

Answer:

(i)

$x \alpha y {3} \\ \frac{x}{y {3} } = k$

(ii)

$\frac{x}{y {3}^{} } = \frac{x}{y {3}^{} } \\ \frac{32}{ {2}^{3} } = \frac{x}{6 {}^{3} } \\ \frac{32}{8} = \frac{x}{216} \\ x = 864$

(iii)

$\frac{32}{8} = \frac{108}{y {}^{3} } \\ {y}^{3 } = 27 \\ y = \sqrt[3]{27 } \\ y = 3$

you have a 4x6 photo of you and your friend. You order a 5x7 print of the photo. Is the new photo similar to the original?

No because 4 times 6 =24 and 5 times 7 =35
