Answer:
Step-by-step explanation:
It is given that the length of triangle base is 26 that is BC=26.
A line, which is parallel to the base divides the triangle into two equal area parts.
Therefore, from the given information, .
Now, since it is given that A line, which is parallel to the base divides the triangle into two equal area parts, thus

I know this is not the answer but how do you add a question
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: Discriminant is 36. There are two real solutions (both different)
Explanation:
The equation 1x^2 - 4x - 5 = 0 is in the form ax^2 + bx + c = 0. We see that
a = 1, b = -4, c = -5
So the discriminant is
D = b^2 - 4ac
D = (-4)^2 - 4(1)(-5)
D = 16 + 20
D = 36 is the discriminant
The discriminant is positive, so there are two different solutions. The solutions are both real.
note: because the discriminant is a perfect square, this means that the two solutions are rational (ie fractions of whole numbers).
