3. The parents of a newborn girl want to invest $1000 in some kind of saving plan that their child could use after her 21st birthday. Savings Plan A will increase the amount in the account by $75 per year for
as long as the account is active. Savings Plan B will increase the amount in the account by 5% per year
as long as the account is open

Write an equation for plan A

Write an equation for plan B

A. 1000x75t=i

B. 1000(1+5%/n)^t

Step-by-step explanation:

i=prt     interest principle rate time

a=p(1+r/n)^t amount principle rate number of times interest is compound time

Hope this helps.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
