For the square.
Let
[tex]Length = L[/tex]
So, the area is:
[tex]Area = Length^2[/tex]
[tex]A_1=L^2[/tex]
The side length of the square equals the diameter of the circle.
So:
[tex]diameter (d) = L[/tex]
The radius is:
[tex]r = \frac{1}{2}d[/tex]
[tex]r = \frac{1}{2}L[/tex]
The area is:
[tex]Area = \pi r^2[/tex]
[tex]A_2 = \pi * (\frac{1}{2}L)^2[/tex]
[tex]A_2 = \pi * \frac{1}{4}L^2[/tex]
[tex]A_2 = \frac{22}{7} * \frac{1}{4}L^2[/tex]
[tex]A_2 = \frac{22}{28} L^2[/tex]
The likelihood that a point will be common to the square and the circle is:
[tex]Pr = \frac{A_2}{A_1}[/tex]
[tex]Pr = \frac{\frac{22}{28} L^2}{L^2}[/tex]
[tex]Pr = \frac{22}{28}[/tex]
[tex]Pr = 78.57\%[/tex]
The above probability is greater than 50% but less than 100%.
Hence, it is likely
Answer:
C. Likely
Step-by-step explanation:
all the points are in the circle so it's likely to choose a point inside the circle
Mica stands 75 feet away from the base of a tree and looks up towards the top of the tree at a 51 degree angle.
Answers
Answer:
Height of the tree = 92.61 feet
Step-by-step explanation:
Given: Distance between base of tree and Mica = 75 feet
Angle of elevation to the top of tree = 51°
Assuming we have to find the height of the tree = H
This can be found by applying simple trigonometry.
The height of the tree becomes perpendicular and distance between base of tree and Mica is base.
Then, tan51° = H/75
⇒ H = 75× tan51° = 92.61 feet

y=38(0.29)^x
what is it
Answers
Answer:
Step-by-step explanation:
y=38(0.29)^x is an exponential function whose initial value (when x = 0) is 38. This function increases steadily from this value, due to the +(0.29) base of this exponential. As x grows increasingly large, the rate at which y is increasing drops steadily.

Answers
Answer:
29
Step-by-step explanation:
In a triangle, a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
Given this formula, we knoe c^2 is the product of 21^2 + 20^2.
This gives you 841. Now you just find the square root of 841 which is 29.
