You know they are parallel because the lines will never intersect or meet. (Two straight lines usually mean it is parallel)
Answer:
ABC = 113°
Step-by-step explanation:
If ABD is 70° and DBC is 43°
ABC is 70°+43° = 113°
Answer:
14.67
Step-by-step explanation:
Mr. James will solve the equation 150x = 2200 for x in one step. Which proportion is the MOST appropriate step for Mr. James to use?
We have the Equation
150x = 2200
Divide both sides by 150
150x/150 = 2200/150
x = 14.666666667
Approximately x= 14.67

The statement which is true is the airplane reaches its maximum height of 81 feet in 12 seconds.
Since the height of the plane is a function given by a parabola, we need to know the equation of a parabola in vertex form
<h3>What is the equation of a parabola in vertex form?</h3>
The equation of a parabola with vertex (h,k) is given by y = a(x - h) + k
Since the height (in feet) of the airplane as a function of time (in seconds after the timer was started) is given by the equation h(t) = −(t − 12) + 81
- Since this is the equation of a parabola in vertex form, comparing h with y, we have that a = -1, h = 12 and k = 81
- Since a = -1 < 0 this implies that the point (h, k) = (12, 81) is a maximum point
So, the statement which is true is the airplane reaches its maximum height of 81 feet in 12 seconds.
