Answer:
A=4 B=-8 C=-3
Step-by-step explanation:
first you must but in the form ax^2+bx+c you get 4x^2-8x-3 so a=4 b=-8 c=-3
You will use the functions soh cah toa. you know that angle b is 90 so the other 2 angles have to add up to 90°. with the Pythagorean theorem we can get that cb is 12 feet. so we now have all side lengths and 1 angle. you can pick out that 53° will be your final answer after doing the basic functions!
S = v x t
= 5.7 x 10^2 x 1.4 x 10 = 7980 Miles
No because the x does not go with the y
Answer:
= 18
Step-by-step explanation:
= 
Cross multiply
5 * c = 30 * 3
5c = 90
Divide both sides by 5
c = 90/5
c = 18
