You fitted a regression model on the height of a particular pine tree, after 20 years of growth, as a function of the elevation the tree is growing in a coastal mountain. You found that linear regression was appropriate to study this question i. e., the relationship was linear. The regression model showed that tree height decreased 0.2 meters per meter gained in elevation and that tree height at sea level height (Om elevation) was predicted to be 110 m. The slope of this model was: (use the correct sign) while the intercept was: . The model predicts that a tree growing at an elevation of 25 m should be m tall. While the predicted elevation in the mountain that a 108 m tall tree will be found ism.

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
