Answer:
5) y = 3x + 1
6) For this question, I would just draw a line that is increasing, and then once it reaches 10 mins I would make a steep line going downward. Something like this: /\
7) Yes, Raoul is correct because Function A's initial value is 0 and function B's initial value is 3.
The expression is:
cos (π / 5) cos (π/7) + sin (π/5) sin(π/7)
This expression can be reduced into a trigonometric function with one angle if we make use of the trigonometric identities. The appropriate identity is:
cos (A - B) = cos A cos B + sin A sin B
If we let
A = π / 5
B = π / 7
Therefore,
cos (π / 5) cos (π/7) + sin (π/5) sin(π/7) = cos (π/5 - π/7) = cos (2π/35)
Answer:
80.6
Step-by-step explanation:
F = 9/5 C + 32
F = (9/5)*27 + 32 Substitute 27 into the equation
F = 243 / 5 + 32 Multiply 9 and 27 together
F = 48.6 + 32 Divide by 5
F = 80.6 Add on 32
A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.
2*27 = 54 Add 30
54 + 30 = 84
This quick way will tell you if you get near the right answer.
Answer:
$10
Step-by-step explanation:
Given that:
Amount earned for 0 mile = $50 (earned for signing up)
Amount earned for walking 1 mile = $60 ($50 for signing up and $10 for. Walking)
Hence, the amount earned per mile walked according to the information given is $10
Total amount earned =. Sign up fee +. Walking fee
$60 = $50 + walking fee
Walking fee = $60 - $50
Walking fee =. $10
Miles walked = 1 mile
Hence , amount earned per mile = $10
