Answer:
0-2 x-intercepts and 0-1 y-intercepts
Step-by-step explanation:
A quadratic function can have anywhere from 0 to 2 x-intercepts. This is possible because a function can have 0, 1, or 2 solutions.
A parabola can also have either 0 or 1 y intercepts. It is possible for the function to not intercept the y axis at all, and it is also possible for it to intercept it exactly one time.
It takes 20.833 minutes to fill a 50 gallon tub
<em><u>Solution:</u></em>
Given that,
It takes 1 & 1/4 minutes to fill a 3-gallon bucket of water with a hose
Let "x" be the time taken to fill a 50 gallon tub
Therefore, from given,
1.25 minutes = 3 gallon
x minutes = 50 gallon
This forms a proportion and we can solve the sum by cross multiplying
Thus it takes 20.833 minutes to fill a 50 gallon tub
Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
Well since the line is headed to the left side, you know it has a negative slope, so B and C can be crossed out. Then, you know that point-slope form is written as y - y1 = m (x - x1)
So, you just plug in the numbers given on the graph, (4,-2)
You should come out with y + 2 = -2 (x - 4)
And that's the equation of the line in point-slope form!!! :)
Hope it helped and you understand it better!
D.) y + 2= -2 (x - 4)
