Answer:

Step-by-step explanation:
We have,
Height of a cone is 12 feet
Volume of the cone is 90 feet
It is required to find the area of the base of the cone.
The base of a cone is circular in shape.
The formula used to find the volume of a cone is given by :

here,
(area of base of cone)

So, the area of the base of the cone is
.
According to the vertex and the directrix of the given parabola, the equation is:

<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:

In which a is the leading coefficient.
The directrix is at y = k + 4a.
In this problem, the vertex is (1,4), hence:

The directrix is at y = 7, hence:


Hence, the equation is:

The answer is 74.5 ahen you divide 298÷4
2X^2+22x+318=1270
2x^2+22x-952=0
x^2+11x-476=0
(x+28)(x-17)=0
x=17
The experimental probability of the computer generating a 2 is 20%.
<h3>What is the experimental probability?</h3>
The experimental probability determines the odds an event would happen based on the results of an experiment.
Experimental probability = ( number of times a 2 was generated / total number of numbers generated) x 100
(16 / 80) x 100 = 20%
