7/30 x 100 = approx 23.3%
This is a cone or a cylindrical pyramid.
Hope this helps :-)
Answer:
22
Step-by-step explanation:
f(x)=(3x+4)-(2-x)
Let x =5
f(5)=(3*5+4)-(2-5)
Do the parentheses first
= (15+4) - (2-5)
= 19-(-3)
= 19+3
= 22
Answer:
- vertex: (-5/8, 7/16)
- axis of symmetry: x = -5/8
Step-by-step explanation:
For quadratic ax²+bx+c, the axis of symmetry is located at x=-b/(2a).
Here, we have a=4, b=5, so the axis of symmetry is ...
... x = -5/(2·4) = -5/8
_____
The vertex y-value will be f(-5/8).
... f(-5/8) = (4·(-5/8) +5)·(-5/8) +2 = (5/2)·(-5/8) +2 = -25/16 +32/16
... f(-5/8) = 7/16
_____
The axis of symmetry is x = -5/8; the vertex is (-5/8, 7/16).
(7,4) and (-1,8) on a graph looks like this
