Answer:
64
Step-by-step explanation:
Answer: D is correctly written in scientific notation.
Step-by-step explanation:
The base has to be between 1 and 10.
A has a base of 16.4 which is greater than 9.
B is not even in scientific because the base it being raise to an exponent
C has 0.71 as base which is less that.
y2 - y1
---------
x2 - x1
3 - 1 2 1
------- = -------- = --------
4 - 0 4 2
Find the y-intercept:
1 = 1/2(0) + b
1 = 0 + b
-0 -0
1 = b
The slope-intercept equation is:
y = 1/2x + 1
so its D
