Answer:
sinθ = 5/13
cosθ = 12/13
tanθ = 5/12
Step-by-step explanation:
Get the remaining side(hypotenuse) first,
hypotenuse^2 = 12^2 + 5^2 (Pyth. theorem)
hypotenuse = 13
sinθ = 5/13
cosθ = 12/13
tanθ = 5/12
1) It tells you in the question c = cost, so cost would be the answer
2) 2.75 is the fixed rate so we would keep it as is. C is the cost which would the total, so c = ?m + 2.75
0.40 per half mile so you put 0.40m because it varies depending on the amount of miles
That makes the equation c = 0.40m + 2.75
3) Now to find how much it costs for 45 miles, you plug 45 for m
c = 0.4 * 45 + 2.75
c = 20.75
Not sure why it isn't an option
Answer:
B.) -3
Step-by-step explanation:
-3 is the only point thats NOT on the line.
Answer:
L = 20 cm, W = 10cm
Step-by-step explanation:
P=2L+2W
P=60,L=2W
60 = 2(2W)+2W
60=4W+2W
60=6W
W=10
plug in L=2W
L=2x10
L=20
