If n denotes a number to the left of 0 on the number line such that the square of n is less than 1/100, then the reciprocal of n
andriy [413]

Answer: E. Greater than 10

Step-by-step explanation:

First, know that number to the left of a number line are negative and the square of any negative number will be positive and a perfect square.

Since the square of the unknown number is less than 1/100 i.e 0.01 then the possible unknown number 'n' can be -0.01 itself, of which the square of -0.01 will give us 0.0001 (1/10,000) i.e a value less than 0.01.

The reciprocal of 1/10000 is 10,000 which is a value greater than 10.

Answer:

7.211103

Step-by-step explanation:

For:

(X1, Y1) = (-3, 4)

(X2, Y2) = (1, -2)

Distance Equation Solution:

d=(1−(−3))2+(−2−4)2−−−−−−−−−−−−−−−−−−−√

d=(4)2+(−6)2−−−−−−−−−−√

d=16+36−−−−−−√

d=5–√2
