Herky and Elaina want to compare their investment accounts to see how much they will have in the accounts after eight years
They substitute their values shown below into the compound interest formula.
Name
Herky
Elaina
Principal
$500
$400
Compound Interest Accounts
Interest Rate Number of Years
5%
8
Compounded
Once a year
Once a year
6%
A = P(1+r)
Which pair of equations would correctly calculate their compound interests?
Herky: A = 500(1 +0.08) Elaina A-400(1+0.08)
Herky: A = (500 x 1) + (0.05) Elaina A- (400 1) + (0.06)
Herky: A - 500(1+0.05) 8 Elaina: A-400(1+0.06)
Herky: A = (500X1) +(0.05) 8 Elaina A = (400x1)+(0.05) 8

answer are

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
