A triangle abc with vertices a (6,8) b(6,12) and c(10,12) is rotated 180 degrees. what are the coordinates of B

1 answer:

4 0

The rule for a rotation by <span>180
</span>(x,y)→(−x,−y)
so B<span>(6,12) will be B'(-6, -12)

answer

</span>B'(-6, -12)

MATH HELP!!!

AfilCa [17]

1220*24 = 29,280 per year

multiply that by number of years until he retires:

761280 / 29280 = 26 years

292800 / 29280 = 10 years

the other 2 arent even years so it should be one of those 2. I would say the larger number

Jayden earned some money doing odd jobs last summer and put it in a savings account that earns 12% interest compounded monthly.

Answer:

$220.18

Step-by-step explanation:

The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:

$A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}$

In Jayden's case:

A(n)=$400
r=12%=0.12
n=5 years
k=12 Months

We want to determine the amount Jayden put in the savings account.

$400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\$
