A savings account grows by 3% each year. Sofia places $500 in the account at the beginning of the year. (a) How much does Sofia
seraphim [82]

Answer:

a) $515

b) $530.45

c) The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.

Step-by-step explanation:

a)

After one year, the amount increased is 3% of the inicial value, so it is 0.03 * 500 = $15

So Sofia has 500 + 15 = $515 at the end of the year.

b)

After the second year, the amount will increase by 3%, but now the amount is 515, so we have 0.03 * 515 = $15.45

So Sofia has 515 + 15.45 = 530.45 at the end of the second year.

c)

The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.

Using substitution or elimination <br><br> 9x+3y=-7<br> y=-3x+4
-Dominant- [34]

Answer:

No solution

Step-by-step explanation:

If we substitute the y into the equation, we get 9x+3(-3x+4)=-7

If we distribute the 3, we get 9x-9x+12=-7

This then cancels out both 9x's and we are left with 12=-7, making it no solution.

What is the domain of the following function? Show work <br> f(x)=(2x-1)/((2x^2)-9x+10)
Romashka-Z-Leto [24]

Step-by-step explanation:

f ( X) = ( 2X - I ) / 2X ^ 2 - 9X + 10

= 2X-1 ) /( 2X- 5 ) ( x - 2 )

set of zeros of denominator are :

2X- 5 . = 0

X= 5/2

or

X-2=0

X=2

set of zeros of denominator = { 5/2 ,2 }

domain = R - { 5/2,2 }
