Answer:
y=-4/2x+-2
Step-by-step explanation:
Let after t hours the distances D1<span> traveled by car A</span>
=> D1<span> = 30 t</span>
Car B starts at 10 am and will, therefore, have spent one hour less than car A when it passes it.
After (t - 1) hours, distance D2<span> traveled by car B </span>
=> D2<span> = 40 (t - 1)</span>
When car B passes car A, they are at the same distance from the starting point and therefore<span> D1 = D2 </span>
=> 30 t = 40 (t - 1)
Solve the equation for t,
=> 30 t = 40t - 40
=> 10 t = 40
=> t = 4
=><span> Car B passes car A at = 9 + 4 = 13 pm.</span>

Answer:
1694 ft
Step-by-step explanation:
The adjacent side of this right triangle is 75 feet in length, and the two given angles are 90 degrees and 67.5 degrees. Since the adjacent side is given and the opposite side is what we are looking for we can use
tan(x) = opposite/adjacent insert the given information into the equation
tan(67.5) = opposite / 75ft multiply both sides of the equation by 75
tan(67.5)*75 = opposite leaving us with the target variable
once you plug that equation into a calculator you get 1694 as your nearest whole answer.
