The relationship is 1,5 because the hot air balloon rises 5 foot per 1 second.
Answer:
30°
Step-by-step explanation:
If chord AB subtends two arcs with measures in the ratio of 1:5, then the measure of minor arc is x and the measure of major arc is 5x. Thus,
Thus, the measure of the angle AOB is 60°. Consider isosceles triangle AOB (because AO=BO=radius of the circle). The angles adjacent to the base AB are congruent, thus
Since line CD is tangent to the circle,
Hence,
20 degrees
vertical angles are equal, so 5x-80=x
solve for x and you get 20
Answer:
Step-by-step explanation:
Given that:
The modeled equation y = 0.2x² - 0.4x - 0.6
To find x- intercepts
y = 0.2x² - 0.4x - 0.6
y = 0.2(x² - 2x - 3)
y = 0.2(x - 3)(x + 1)
Suppose the upward parabola cuts x axis at x = 3 and x = - 1
Then, the length of the intercepts will be = 3 -(-1)
=4
We can say that the trees will be 4 unit apart.
To find y-intercepts;
y = 0.2(0)² - 0.4(0) -0.6
y = -0.6 meters
