grandymaker [24]

Answer: f(x)=-(x-5)^{2}(x+2)

Step-by-step explanation:

There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form f(x)=a(x-5)^{2}(x+2) for some constant a.

To find a, we can substitute the coordinates of the y-intercept, (0, -50).

-50=a(0-5)^{2}(0+2)\\\\-50=50a\\\\a=-1

So, f(x)=-(x-5)^{2}(x+2)

Grace [21]

Answer: 77.283km^{2}

Step-by-step explanation:

The formula for the lateral area of a cone L.A is:

L.A=\pi r h

Where:

r=10km is the radius of the circular base of the cone

As we know its diameter d=20km, its radius is r=\frac{d}{2}=10km

h=2.46km is the height of the cone

L.A=\pi (10km)(2.46km)

L.A=77.283km^{2} This is the lateral area of the volcano with the shape of a cone
