From the inscribed circle, AE and AD are the radius of the circle while BE and BD are the tangents.
<h3>What is an inscribed circle?</h3>
An inscribed circle simply means the largest circle that's contained in a triangle.
An inscribed circle touches its tangent to the three sides. In this case, AE and AD are the radius of the circle while BE and BD are the tangents. Also, angle ABE and ABD are 60°.

Answer:
Option A is right.
Step-by-step explanation:
Given that a new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 50 women over the age of 50 used the new cream for 6 months. Of those 50 women, 44 of them reported skin improvement(as judged by a dermatologist)

(Right tailed test)
Sample size = 50
Std error of proportion =
p difference=
Z statistic = p diff/std error = 6.928
p value <0.00001
Since p is less than alpha, reject null hypothesis.
A. We can reject the null hypothesis that p=0.4 and accept that p>0.4. That is, the cream can improve the skin of more than 40% of women over 50.
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
= (5/2)
= 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.
x = 8
Since x = 8, you can plug in/substitute 8 for "x" in the equation:



2.82842
2.83 You answer is the 4th option
x = 9
Plug in 9 for "x" in the equation



4 Your answer is the 1st option
