Which number is the best estimate of 866,214,000,000 using powers of 10
a) 9 × 10¹¹
b) 8 × 10¹¹
c) 10 × 11¹⁰
d) 8 × 10-¹¹
Answer:
a) 9 × 10¹¹
Step-by-step explanation:
When we want to estimate a number using the power of 10, we are trying to write the number in a standard form.
We are to estimate :866,214,000,000 using powers of 10
Hence,
8.66214000000 × 10¹¹
We round up to the nearest whole number
= 9 × 10¹¹
Therefore, the best estimate for 866,214,000,000 using powers of 10
= 9 × 10¹¹
If the 3 points are collinear, then the slopes of all line segments connecting the points are the same.
Thus,
-6 - (-8) 2
m = ------------- = -------- = -1/2
-7 - (-3) -4
Then the following must be true:
4-(-6) 10
-1/2 = ------------ = ---------
c - (-7) c + 7
Cross multiplying, -(c+7) = 20, and c+7 = -20, so that c = -27
