A description of a dilation includes the scale factor (or ratio) and the center of the dilation. The center of dilation is a fixed point in the plane. If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink

The Kellys are saving up to go on a family vacation in 2 years. They invest $3200 into an account with an annual interest rate o
ryzh [129]

Answer:

$3,273.14

Step-by-step explanation:

-We first calculate the effective interest rate of 1.13% compounded daily:

i_m=(1+i/m)^m-1\\\\=(1+0.0113/365)^{365}-1\\\\=0.011363909

#Now, we calculate the compounded amount after 2 years using this rate:

A=P(1+i)^n\\\\=3200(1.011363909)^2\\\\\\=3273.14

Hence, the compounded amount after 2 years is $3,273.14

I need help please and thank you
BartSMP [9]

Answer:

  3.33×10⁴

Step-by-step explanation:

You can use the hint, or you can use a common exponent. Here is the latter case.

  (3.9×10⁴) -(5.7×10³) = (3.9×10⁴) -(0.57×10⁴) = (3.9 -0.57)×10⁴

  = 3.33×10⁴

_____

With a little practice, you can see the effect on exponents of moving the decimal point. Here, we have ...

  5.7×10³ = (0.57×10)×10³ = 0.57×(10×10³) = 0.57×10⁴

__

When adding or subtracting in scientific notation, all that is required is that the exponents of all the numbers be the same. The hint says make all the exponents be 0. Above, we have chosen to make them all be 4. You could also use 3:

  (3.9×10⁴) -(5.7×10³) = (39×10³) -(5.7×10³) = (39 -5.7)×10³

  = 33.3×10³ = 3.33×10⁴
