kari74 [83]

Answer:

Extra snow needed > 0. 3 inch

Step-by-step explanation:

Given that:

Cancelation occurs when > 2.5 inch of snow accumulates each hour

Accumulation rate = 11/5 inch per hour

Extra snow Accumulation needed to cancel. School ;

Extra snow needed > cancelation volume - current rate

Extra snow needed > (2.5 - 11/5)

Extra snow needed > 0. 3 inch

Find the domain of the funtion 4/x-7
dedylja [7]
Domain means which values the function can have which make it true or Possible to solve

So all you got to do is set the denominator = to 0 and solve for x
You will get x=7

4/(7-7) is not possible

So x cannot equal to 7 because you cant divide a number by 0!

For any quadratic functions, ax² + bx + c, we can easily find the x-coordinate of its vertex through the use of the formula below.

x_{vertex} = \frac{-b}{2a}

where a and b are the coefficients of the function. For f(x), we have a = -1 and b = -16. Thus, we have
 
x_{vertex} = \frac{-16}{2(-1)}
x_{vertex} = 8

Since we now have the x-coordinate of the vertex, we can just easily substitute 8 into f(x) as shown below.

y_{vertex} = f(8) = -(8)+16(8)-60
y_{vertex} = 60

Thus, the vertex of f(x) is (8, 60). The vertex of the function shows the maximum value that the function can reach. For this particular case, the vertex represents the maximum profit that the shop owner could earn.

The x-intercepts of the function are the values of x when f(x) is zero. By equation f(x) with zero, we can solve the quadratic equation to find the x-intercepts as shown below.

-x^{2}+16x-60 = 0
x^{2}-16x+60=
(x-6)(x-10) = 0
x = 6
x=10

From this, we can see that the x-intercepts are (6, 0) and (10, 0). We just discussed that the x-intercepts are the values of x when y is zero. So, for this case it means that the shop does not earn a profit if they sell 6 or 10 candles. Basically, the x-intercepts represent the number candles sold if the shop wants to break even.
