Step-by-step explanation:
This right triangle is on a grid.
The area is the height * base/2
The base is on a line segment parallel to the x axis which is 6 squares.
The height is on a line segment parallel to the y axis which is 2 squares
The area is the height * base /2
Area = 6 * 2 /2 = 12/2 = 6 square units.
Answer:



Step-by-step explanation:
a. a, b, c
Quadratic equations in standard form are written as:

The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.


b. Y-intercept
The y-intercept for a quadratic is c.
You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).


We know that c=2, so the y-intercept is c.
c. Maximum/minimum
The entire quadratic is positive, so the quadratic opens up and has a minimum.
This is an arithmetic sequence.
d= 0.5-3=-2.5
d= - 2.5
a(1)= 13
a(n) = a(1) +d(n-1)
a(n)=13-2.5(n-1)=13-2.5n+2.5= 15.5 - 2.5n
a(n)= 15.5 - 2.5n
Answer C. a(n)= 15.5 - 2.5n
