(x-5) = 0 or (x+2)=0
so x could be 5 or -2
i guess, u can check it with calculator
To solve for the total price:
1.075(50) = 53.75
She will have to pay $53.75 in total.
Answer:
63
Step-by-step explanation:
The radii of the frustrum bases is 12
Step-by-step explanation:
In the figure attached below, ABC represents the cone cross-section while the BCDE represents frustum cross-section
As given in the figure radius and height of the cone are 9 and 12 respectively
Similarly, the height of the frustum is 4
Hence the height of the complete cone= 4+12= 16 (height of frustum+ height of cone)
We can see that ΔABC is similar to ΔADE
Using the similarity theorem
AC/AE=BC/DE
Substituting the values
12/16=9/DE
∴ DE= 16*9/12= 12
Hence the radii of the frustum is 12
In this problem, the x intercept is 3.5 because the line crosses through the x axis at the point (3.5,0)
