If a quadratic equation has solutions and , then we can write it as
So, in your case, we have (let me write 1.5 as 3/2 and -0.25 as -1/4)
If we don't want decimal coefficient, we can multiply the whole expression by 8:
Answer:
The volume of the cone is
Step-by-step explanation:
We know that formulas
Volume of cylinder is
Volume of cone is
we are given
A cone and cylinder have the same height and the same base radius
So, both will have same radius and height
now, we can find ratios
now, we can simplify it
we are given
the volume of the cylinder is 81 cm^3
so,
now, we can plug it and solve for V2
So, the volume of the cone is
600 + 9.5x (less than or equal to) 900
600 fixed amount
9.5 is the variable changing amount and differs among number of students taken
Step-by-step explanation:
Slope (m) = 2/ 5
Y-intercept (c) = - 7
writing in slope intercept form
y = mx + c
y = 2/5 x - 7
Hope it will help :)
