Since the triangles are the same, just flipped that means that all angles and segments are the same as well
I'm not sure if that's the "correct" way to prove it but that's why they're equal
Answer:
=−5r+5
Step-by-step explanation:
Let's simplify step-by-step.
−5−5r+10
=−5+−5r+10
Combine Like Terms:
=−5+−5r+10
=(−5r)+(−5+10)
=−5r+5
Answer:
- a) p(10) ≈ 48.10
- b) about 1.00 million/year
Step-by-step explanation:
a) Use t=10 in the given formula and do the arithmetic.
39.07×1.021^10 ≈ 48.0951 ≈ 48.10 . . . millions
__
b) The derivative of p(t) is ...
p'(t) = p(t)·ln(1.021) ≈ 0.8120·1.021^t
p'(10) ≈ 0.99954 ≈ 1.00 . . . . millions per year

➷ Work out the time for Cardiff to Swansea:
time = distance/speed
Substitute in the values:
time = 69/60
Solve:
time = 1.15 hours = 69 minutes
Add together the total time and distance:
72 + 69 = 141
48 + 69 = 117
speed = distance/time
speed = 141/1.95
speed = 72.3 km/h
