I think you left out something, is it -4x+1

Use rounding (to the nearest 10) to estimate the product of 3217 X 44.

Lorico [155]

So using whole number rounding I believe the answer you should get would be 141,550 as 3217 x 44 is equals to 141,548 so the answer may be 141,550 since 50 is the closest ten number to 48, with a distance of only 2 numbers.

Help plzz i will give you brianliest Which best describes the graph of the function f(x) = 3(1.8)^x A) The graph passes through

Answer:

Step-by-step explanation:

Start with why C isn't the answer.

y = 1.8^0 . The power is zero. Anything to the zero power (anything except 0 to the 0 power) is 1. So 1.8^0 is 1 not something else. C assumes that somehow 0,1.8 turns into 1.8. It does not. The second part is also wrong but you don't need it. However here it is.

x = 0 y = 3

x = 1 y = 3 * 1.8 = 5.4

x = 2 y = 3 * 1.8^2 = 3*3.24 = 9.72

You should be able to see that if you multiply 5.4 by 3, you don't get 9.72

C just does not work.

=======

The actual answer is A. That's exactly what the graph does. If you multiply 5.4 * 1.8 you should get 9.72. Just for completeness, I've included the graph.
