Answer: SECON OPTION.

Step-by-step explanation:

The correct form to apply thee Distributive property is the shown below:

\frac{(-3)(-8)}{8}+\frac{(-3)(-16d)}{8}+2d=24

Keeping on mind that:

(-)(-)=+

You obtain:

\frac{24}{8}+\frac{48}{8}d+2d=24

Simpliying, the have:

3+6d+2d=24

Add the like terms and solve for <em>d:</em>

<em> </em>8d=24-3\\8d=21\\d=\frac{21}{8}

Therefore, you can conclude that Celia made the first error in STEP 1. She should have also distributed -\frac{3}{8} over -16d to get 3+6d+2d=24.

Please help me with this problem. I'm kind of stuck and don't know what to do.

Try this option:

1) if csc(u)=9, then 1/sin(u)=9 and sin(u)=1/9;

2) if sin(u)=1/9, then cos(u):

cos(u)=\sqrt{1-sin^2(u)}=\sqrt{1-\frac{1}{81}}=\frac{4\sqrt{5}}{9};

3) if \ sin(u)=\frac{1}{9} \ and \ cos(u)=\frac{4\sqrt{5}}{9}, then

sin(2u)=2sin(u)*cos(u)=\frac{8\sqrt{5}}{81};

cos(2u)=cos^2(u)-sin^2(u)=\frac{80}{81}-\frac{1}{81}=\frac{79}{81};

tan(2u)=\frac{sin(2u)}{cos(2u)}=\frac{\frac{8\sqrt{5}}{81}}{\frac{79}{81} }=\frac{8\sqrt{5}}{79}.

Logan took out $23,400 in student loans to attend college at a compound interest rate of 5%. He deferred payments for two years.
blagie [28]

Answer:

$25,740

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 23400 × 0.05 × 2 = 2340

I = $ 2,340.00

The simple interest accumulated

on a principal of $ 23,400.00

at a rate of 5% per year

for 2 years is $ 2,340.00.
