Answer:
Step-by-step explanation:
first solve the first part then subtract it from the other part.
that is the first part.
the second part solve it too.
so put it all together
<u>Your question:</u> The amount of water leaking from a water tank can be modeled with the function f(x) = −x3 − 10x2 − x + 120, where x measures the number of minutes since the leak began and f(x) measures the volume of the tank. During what time period is there water in the tank? (0, 3) (0, 3]
(0, 3) is the best answer
1/2n + 15 = 9 <== ur equation
1/2n = 9 - 15
1/2n = - 6
n = -6 * 2
n = - 12 <== ur solution
So you know that the sum of angles in a triangle is 180°.
You know two of the angles in triangle WXZ. The two angles are angle WXZ, which is 50° and angle XWZ, which is 90°.
Now you can calculate angle WZX, by:
180-50-90=40°.
