The equation is true.
y^13/y^12 = y^8 * y^-9
y=y^8 * y^-9
y=y^-1
y=1/y
y-1/y=0
y
y^2 - 1 = 0
y = 1 , -1

In the opposite figuret triangle OAB has an area of 72 cm2 and. Triangle ODC has an area of 288 Cm2 Then XandY equal​
Lisa [10]

area of OAB = 72 = (1/2) sin (AOB) * OA * OB solve the above for sin(AOB) to find sin(AOB) = 1/2 area of ODC = 288 = (1/2) sin (DOC) * OD * OD Note that sin(DOC) = sin(AOB) = 1/2, OD = 18 + y and OC = 16 + x and substitute in the above to obtain the first equation in x and y 1152 = (18 + y)(16 + x)...

<h2>Answer: </h2><h2>3.19</h2><h2>______________________________________</h2><h3>Honey, all you need to do is multiply.</h3><h3>−2.75 by −1.16</h3><h2>______________________________________</h2>

Since the rational numbers are in parenthesis next to each other it means you have to multiply both of the numbers together.

Hope this helped at least a little bit!~

Explanation and answer please :)

$20,000 is between $15,000 and $49,999, so we'll use the interest rate of 6.5% (see row 3)

r = 6.5% = 6.5/100 = 0.065

We'll use the decimal form of the interest rate as it is most common for financial math problems.

P = 20,000 is the amount deposited

t = 1 year is the amount of time

We will plug those values into the formula

i = P*r*t

to get the following:

i = P*r*t

i = 20000*0.065*1

i = 1300

So Mark earns $1,300 in simple interest each year.
