Answer:
vertex: (-2, 4)
Step-by-step explanation:
Use your regression calculator to find the parameters of the quadratic model.
The vertex form equation is ...
y = -3(x +2)^2 +4
so the vertex is (-2, 4).
__
The standard form equation is the expansion of the above:
y = -3x^2 -12x -8
Answer:
353
Step-by-step explanation:
95 - 10 + 2(141 - 7)
following PEMDAS we will do parenthesis first
95 - 10 + 2(134)
multiplication is next
95 - 10 + 268
addition and subtraction are interchangeable when using PEMDAS but you do whatever comes first. since it's subtraction first in this equation we will do 95 - 10.
85 + 268
now we are left with addition
85 + 268 = 353
Answer:
4m
Step-by-step explanation:
- v=4/3 pi r^3
- substitute 267.95=4/3×3.14×r^3
- 267.95= 12.56r^3/3
- multiply by the reciprocal on both sides 64=r^3
- find the cuberoot on both sides to remove the cube hence 4=r
