Answer:
Triangle ABE and triangle CDE are congruent by using SAS theorem.
Step-by-step explanation:
It is given that e is the midpoint of BD and .
(E is midpoint of BD)
Angle AEB and angle CED are vertical opposite angle and the vertical opposite angles are always same.
(Given)
So by using SAS theorem of congruent triangles.
Therefore triangle ABE and triangle CDE are congruent by using SAS theorem.
Given:
Growth rate = 30% decrease
To find:
The growth factor associated with the given growth rate.
Solution:
The general exponential function is:
Where, a is the initial value, r is the growth rate in decimal and is the growth factor.
It is given that the growth rate is 30% decrease. So,
Now,
Therefore, the growth factor is 0.7.
Answer:
V = 2143.57
Step-by-step explanation:
To find the volume of a sphere you need to use this formula:
r = radius
Solve:
You need the radius from the diameter. Divide 16/2 which is
8.
V = 2143.57
