(a) It is leaking 18 liters per minute.

Explanation : From 15 minutes to 20 minutes, your starting point at 15 is 590 liters and at 20 you have exactly 500. Next you have 25 which is now at 410. So it's leaking 90 liters every five minutes, so of course dividing the two (90 ÷ 5) you get 18.

(a)² it increases for about the same time that it would decrease of course.

(b) The vat started at 860 liters before they started draining it.

Explanation : Well, all it takes is just working backwards, add 90 liters to the liters at 15 minutes and deduct five minutes from 15. Do this process until you arrive at 0. It's simple

Two adjacent angles form a complementary relationship. One angle is twelve more than twice the other angle. Draw a picture to re
Anon25 [30]

Answer:

The angles are 26 and 64

Step-by-step explanation:

When two angles are complementary, what this means is that the add up to 90 degrees

Now, let’s say one of the angles is x, the other angle is 12 more than twice it; mathematically that would be 2x + 12

Since they add up to be 90, we have

x + 2x + 12 = 90

3x + 12 = 90

3x = 90-12

3x = 78

x = 78/3

x = 26

The other angle is 2x + 12 = 2(26) + 12 = 52 + 12 = 64

Check all the statement(s) that are true about the polynomial function graphed.
slava [35]
The true statements are:

2 - we can tell this by looking at the far right of the graph, as the slope is going downwards, therefore the leading coefficient must be negative

3 - this is a cubic, meaning its degree is 3

6 - by looking at the graph, we can see that there are 3 points where it cuts the x axis, hence 3 real zeros

7 - even multiplicity is where the curve "bounces off" the x axis and does not cross it. This curve have no zeros with even multiplicity

Hope this helped!

Citrus2011 [14]

Answer:

15.2 mph

Step-by-step explanation:

2.4÷(x+4)=1.4÷(x-4)

1.4(x+4)=2.4(x-4)

1.4x+5.6=2.4x-9.6

-x=-15.2

x=15.2

Hope this helps!
