Answer:
40.80 km
Step-by-step explanation:
Given: AP (opposite)= 33 km
PB(adjacent)= 24 km
Now, finding the value of AB (hypotenous)
Using the pythagorean theoram to solve it.
⇒
⇒
⇒
Taking square root on both side, remember;
⇒
∴ AB= 40.80 km
The simplified expression is (r) (4
x s³) is 4r³.
The amount of times a number has been multiplied by itself is shown by its exponent. The result of multiplying 8 by itself n times is represented as follows:
8 x 8 x 8 x 8 x …..n times = 8n
Given:
(r) (4
x s³)
Now, using the law of exponents we have
So,
(r) (4
x s³)
= 4 x
= 4r³ x s°
= 4r³
Hence, the simplified expression is (r) (4
x s³) is 4r³.

Answer:
a) Parallel when a = -2/3
b) Perpendicular when a = 6
Explanation:
a) For two parallel lines slopes are equal.
So, 6y=−2x+4 and 2y=ax−5 parallel if they are slopes equal.
Slope of 6y=−2x+4, comparing with y = mx + c
So, m = -2/6 = =-1/3
For 6y=−2x+4 and 2y=ax−5 to b parallel we have slope of 2y=ax−5 equal to -1/3
Slope of 2y=ax−5
m = a/2
We have a/2 = -1/3
a = -2/3
b) For perpendicular lines product of slope is -1.
So we have
