Step-by-step explanation:

Given 

f(x) = x² - 2x + 3

Now

f(-2) = (-2)² - 2 * ( -2 ) + 3

 = 4 + 4 + 3

 = 11

f(3) = 3² - 2 * 3 + 3

 = 9 - 6 + 3

 = 12 - 6

 = 6

Hope it helps :)

Ksenya-84 [330]

Answer:

-2/a³ m/s
-2 m/s
-1/4 m/s
-2/27 m/s

Step-by-step explanation:

The velocity is the derivative of position:

v = ds/dt = (d/dt)(t^-2) = -2t^-3

For t=a, the velocity is

-2a^-3 = -2/a³ . . . . meters per second

For t=1, the velocity is ...

-2·1³ = -2 . . . . meters per second

For t=2, the velocity is ...

-2·2^-3 = -2/8 = -1/4 . . . . meters per second

For t=3, the velocity is ...

-2·3^-3 = -2/27 . . . . meters per second

Kylie starts with $145 in her piggy bank. Each month she adds $20.

djverab [1.8K]

Kylie's first month collection, a1= $ 145

Second month collection , a2= $145+ 20

Third month collection, a3 = $145 +2*20

so for n months collection = an-1+20

We get an= 20 + an-1 and a1=145
