Explanation:
The vertical angles at C are congruent with each other, so we have the necessary conditions to invoke the SAS congruence postulate:
∆BCA ≅ ∆ECD
BA ≅ ED by CPCTC (corresponding parts of congruent triangles are congruent)
35. 20+15=30. 2 tens=20+15 hope this helps!
If you would like to estimate 1/5 percent of 201, you can calculate this using the following steps:
1/5 percent of 201 = 1/5% of 201 = 1/5% * 201 = 1/5 / 100 * 201 = 1/500 * 201 = 201/500 = 0.402
Result: 1/5 percent of 201 is 0.402.
Answer:
a)
b) As t increases from 3 to 6, v varies from 18 gallons to 12 gallons.
Step-by-step explanation:
The volume of the tank in terms of the time can be described by the following equation:
In which V(0) is the initial volume and a is the hourly decrease rate.
a. Write a formula that expresses v in terms of t.
The tank initially contains 24 gallons of water, which means that
Drains at a constant rate of 2 gallons per hour, so
Then
b. As t increases from 3 to 6, v varies from _________ to _________
So as t increases from 3 to 6, v varies from 18 gallons to 12 gallons.
Answer:
Step-by-step explanation:
Find dy/dx of the ellipse at (2,3)
Using Implicit Differentiation
Differentiate both sides of the equation with respect to x
isolate the term dy/dx
Evaluate at point (2,3)
For x=2, y=3
