Answer:
<em>In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables). The case of one explanatory variable is called simple linear regression. For more than one explanatory variable, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable.</em>
C=2pr
r=C/(2p) and we are given C=85 so
r=85/(2p) meters
r≈13.53 meters (to nearest one-hundredth of a meter)
Step-by-step explanation:
BC is the bisector of 
From equations (1) & (2)
(Because sides opposite to equal angles are equal)
Hence Proved
Answer:
To review, depending on how you organize it, a quadratic equation can be written in three different forms: standard, intercept and vertex. No matter the form, a positive a value indicates a concave-up parabola, while a negative a value means concave down.
