Question 1: Verify that parallelogram ABCD with vertices A(-5,-1), B(-9,6), C(-1,5), and D(3,-2) is a rhombus by showing that it
is a parallelogram with perpendicular diagonals.
Question 2 and 3 are down below.
Please show all work. Thank you.
Question 2 and 3 are down below.
Please show all work. Thank you.
1 answer:
The first one can be proven by graphing the parallelogram and the diagonals.
The measure of angle 2 is 160 because it is a vertical angle to angle 1. The measure of angle 3 is 10 because the two other angles must each be 10 in order for the sum of all three angles to equal 180 for the triangles.
I have no idea for the third one however.
Hope this helps!

Answer:
Option A)
Step-by-step explanation:
We are given the following in the question:
V varies jointly as h and the fifth power of r.
Combing the two equations, we get,
Now, removing the sign of proportionality and adding the constant of proportionality, we get,
where k is the constant of proportionality.
Thus, the correct answer is
Option A)
