Answer:
669
Step-by-step explanation:
12+73*9=669
Answer:
See explanation.
Step-by-step explanation:
(i) 5^3 = 125
log 5^3 = log 125
Using the rule log a^n = n log a
3 log 5 = log 125.
(ii) 3^-2 = 1/9
-2 log 3 = log 1/9
(iii) 10^-3 = 0.001
-3 log 10 = log 0.001
(iv) 81^3/4 = 27
3/4 log 81 = log 27.

Answer:
- JK slope: -1/3
- KL slope: 3
- JL slope: -7
- is
- two of the slopes have a product of -1
Step-by-step explanation:
The slope formula is useful.
m = (y2 -y1)/(x2 -x1)
__
JK slope = (1 -2)/(3 -1) = -1/3
KL slope = (-5-1)/(1-3) = -6/-2 = 3
JL slope = (-5-2)/(1-0) = -7
We observe that slopes (-1/3) and (3) have a product of -1, so those line segments are perpendicular. The triangle is a right triangle.
