Answer:
(2,0)
Step-by-step explanation:
-1-1 = 2
-3+3=0
Taking x2 and x1 and y2 and y1 we have found our slope
<em><u>Answer:</u></em>
A or x = 1
<em><u>Step-by-step explanation:</u></em>
So we can see from the most right column that the sum of the three number is 9 (2 + 4 + 3) so we know that every row or column has to add up to 9. We want to find x so we must make sure that, 8 + 0 + x should be 9 and 2 + 6 + x should be 9. From 8 + 0 + x, we know that 8 + 1 is 9 so x is 1. We can also see that 2 + 6 is 8 and 8 + 1 is 9 so x = 1.
<u>Answer:</u>
The correct answer option is B. 1/5.
<u>Step-by-step explanation:</u>
We are given four fractions in the answer options and we are to determine whether which one of them has terminating decimal as its decimal expansion.
Terminating decimal means a decimal value which has a finite amount of numbers and has an end to it.




Therefore, the correct answer is 1/5.
Answer:
height = 9.28m
Step-by-step explanation:
Sum of angle in a triangle = 180°
To find the third angle, we have
180° = 71° + 62° + α
180° = 133° + α
α = 180° - 133°
α = 47°
To find the height use sine rule
h/sin47° = 12/sin 71°
h(sin71°) = 12sin47°
h = 12sin47° / sin71°
h = 12(0.7314) / 0.9455
h = 8.7768/0.9455
h = 9.28m
