Answer:
1/26
Step-by-step explanation:
A deck of cards has 52 cards in it. 2/4 or 1/2 of the deck is red (both hearts and diamonds). Therefore, the chance of pulling any red cared from the deck is 1/26.
<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
13 meters is around 512 in
to get that you do 13x39.37
To find perimeter you add up all the sides so 5cm+6cm+17cm+8cm. This will get you 36cm.

Step-by-step explanation:
The leading coefficient of this cubic (odd-degree) function is negative, so the overall shape of the curve will be downward-sloping (\). The zeros of the factors are at x=-6 and x=0 (multiplicity 2), so we know the first crossing of the x-axis will occur at x=-6. The graph will touch, but not cross, the x-axis at x=0 and continue descending from there.
__
The local minimum will be located 2/3 of the way from the "touch" point to the other x-intercept, so is at x=-4. The value of the function there is ...
y = -(-4)²(-4+6) = -32
The graph is symmetrical about the inflection point halfway between the local extremes, which point is (-2, -16). Then another point on the curve will be 6 units to the right of the local minimum, at (2, -32).
