Point (-9,7) lies in quadrant II
Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82
Answer:
First question 0.3, but you should put a line on top of the 3.
Im not gonna give you all the answers for the next ones cuz you should learn this, but basically you do the denominator divided by the numerator and if a number repeats put a line over the other number it repeated to the end.
Sorry this is bad...
Answer:
A-B=x^2-x+1
Step-by-step explanation:
A-B=3x^2+5x-6+(-2x^2-6x+7)
=3x^2+5x-6-2x^2-6x+7
=x^2-x+1
Answer:
Step-by-step explanation:
Note that 128 = 64*2. The square root of 128 is thus 8sqrt(2). Answer B is the only one that could be correct.
