Answer:

Step-by-step explanation:

Angle 1 is 146

Angle 2 is 180-146 (lines are 180 degrees)

180-146 = 34

Angle 2 and Angle 4 are congruent (equal) because they are vertical angles.

34 + 34 = 68

Answer:

Step-by-step explanation:

1 and 2 are supplementary, making the sum of the measures = 180. 180-146 = 34. 2 is a vertical angle to 4. 4=34. 34+34=68

What happens to the inequality symbol when you multiply or divide each side by a positive number?

Pani-rosa [81]

If you multiply or divide by a positive number the inequality sign DOES NOT CHANGE!

If you multiply or divide by a negative number the inequality sign flips around and becomes the opposite.

If a tank holds 5000 gallons of water, which drains from the bottom of the tank in 40 minutes, then Torricelli's Law gives the v

pochemuha

Answer:

V'(t) = $-250(1 - \frac{1}{40}t)$

If we know the time, we can plug in the value for "t" in the above derivative and find how much water drained for the given point of t.

Step-by-step explanation:

Given:

V = $5000(1 - \frac{1}{40}t )^2$ , where 0≤t≤40.

Here we have to find the derivative with respect to "t"

We have to use the chain rule to find the derivative.

V'(t) = $2(5000)(1 - \frac{1}{40} t)d/dt (1 - \frac{1}{40}t )$

V'(t) = $2(5000)(1 - \frac{1}{40} t)(-\frac{1}{40} )$

When we simplify the above, we get

V'(t) = $-250(1 - \frac{1}{40}t)$

If we know the time, we can plug in the value for "t" and find how much water drained for the given point of t.
