See below for the terms, coefficients, and constants in the variable expressions

<h3>How to determine the terms, coefficients, and constants in the variable expressions?</h3>

To determine the terms, coefficients, and constants, we use the following instance:

ax + by + c

Where the variables are x and y

  • Then the terms are ax, by and c
  • The coefficients are a and b
  • The constant is c

Using the above as guide, we have:

A) 2b + 2ac+5

  • Terms: 2b, 2ac, 5
  • Coefficient: 2, 2 and 5
  • Constant 5

B) 34abx + 16y +1

  • Terms: 34abx, 16y, 1
  • Coefficient: 34ab, 16
  • Constant: 1

C) st +4u + v

  • Terms: st, 4u, v
  • Coefficient: 4

D) 14xy + 6

  • Terms: 14xy, 6
  • Coefficient: 14, 6
  • Constant 6

E) 14x + 12y

  • Terms: 14x, 12y
  • Coefficient: 14, 12

F) 3+ 6-7+a

  • Terms: 3, 6, -7, a
  • Coefficient: 1
  • Constant: 3, 6, -7

A hexagonal pyramid is cut by a plane as shown in the diagram. What is the shape of the resulting cross section?
tiny-mole [99]
Cross section is a surface that is exposed after slicing or making a cut through an object. If a hexagonal pyramid is cut horizontally then the cross section should be an hexagon as well since the base is a hexagon. However, when it is cut vertically the resulting shape would be a triangle.

Create the equation of a quadratic function with a vertex of (5,6) and a y-intercept of -69
Elena L [17]
If the y-intercept is at -69, meaning the point is (0, -69), thus x = 0, y = -69

\bf ~~~~~~\textit{parabola vertex form}&#10;\\\\&#10;\begin{array}{llll}&#10;\boxed{y=a(x- h)^2+ k}\\\\&#10;x=a(y- k)^2+ h&#10;\end{array}&#10;\qquad\qquad&#10;vertex~~(\stackrel{}{ h},\stackrel{}{ k})\\\\&#10;-------------------------------\\\\&#10;vertex~(5,6)\quad &#10;\begin{cases}&#10;x=5\\&#10;y=6&#10;\end{cases}\implies y=a(x-5)^2+6&#10;\\\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;x=0\\&#10;y=-69&#10;\end{cases}\implies -69=a(0-5)^2+6&#10;\\\\\\&#10;-75=25a\implies \cfrac{-75}{25}=a\implies a=-3&#10;\\\\\\&#10;therefore\qquad \boxed{y=-3(x-5)^2+6}
