Hi
You can choose to points (x,y) which solve the equation, like (0,-3) and (4,0) and then draw a line through the points.
Answer:
-2x^2-6x-15
Step-by-step explanation:
Answer:
and ![As=900 cm^{2}](https://tex.z-dn.net/?f=As%3D900%20cm%5E%7B2%7D)
Step-by-step explanation:
At=As+Ar; A=b.h and
, then: At=(x+120)x so
(x+120)x=4500,
Applying cuadratic equation formula:![\frac{120+-\sqrt{120^{2} -4.1.-4500} }{2} =-\frac{120+-\sqrt{14400+18000} }{2}= x1=30 and x2=-150, finally Xs=30cm, and As=900cm^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B120%2B-%5Csqrt%7B120%5E%7B2%7D%20-4.1.-4500%7D%20%7D%7B2%7D%20%3D-%5Cfrac%7B120%2B-%5Csqrt%7B14400%2B18000%7D%20%7D%7B2%7D%3D%20x1%3D30%20and%20x2%3D-150%2C%20finally%20Xs%3D30cm%2C%20and%20As%3D900cm%5E%7B2%7D)
You can do this on a calculator if you search up online radius and height measurement calculator.
Answer:
your answer would be 0.052
