A) 17.69
You just substitute the h for 3
Answer: x= 22.5, angle B = 67.5
Step-by-step explanation:
90+3x+x= 180
4x = 90
x=22.5
3(22.5)= 67.5
Answer: y = x + 2 OR f(x) = x + 2
Step-by-step explanation:
Calculating slope:
Remember rise over run; when going from one point to another point, in this case from (-3, -1) to (0,2), locate the distance moved in the x and y directions. This scenario moves 3 up and 3 right, meaning a positive slope of one. However, if the line was directed left, your slope would be negative.
Finding y-intercept:
Where does the line intersect the y-axis and have a x-value of 0? This is your y-intercept --> (0,2).
Write Equation:
y = mx +b
y = 1x + 2
y = x + 2 <em>(your final answer)</em>
so the basic formula for this d = rt
where d is the distance , r is the speed and t
is time
3800 – 120t = 520 + 40t ( this is the altitude
of each plane are equal)
Solve for t
T = 20.5 min time it takes for the planes to be
at the same altitude
3800 – 120(20.5) = 1340 ft
