Answer:
Step-by-step explanation:
This is an equilateral triangle.
The altitude bisects the 60 degree angle, so a=30
b=60 since its an interior angle of the isosceles triangle.
e = 4 since the two triangles formed by the altitude are congruent.
c = 8 since the side length is 4 + 4 = .
f = 4sqrt3 by the properties of 30 60 90 triangles.
The surface area of a sphere is given by
We deduce
So, in your case, the radius is
The volume of a sphere is given by
So, we have
Y = -3/4x + 6
you write in the y=mx+c form!
m= the slope
c = the y-intercept. (it is the second number of the coordinates)
The probability is 1/650.
There is 1 a out of 26 letters; P(a) = 1/26
There is 1 e out of 26 letters; however, since it comes after drawing the a and is done without replacement, it is out of 25: 1/25
Together, their probabilities are 1/26(1/25) = 1/650
