Answer:
b^2-4ac >0 the roots are real
Step-by-step explanation:
b^2-4ac >0 the roots are real
b^2-4ac = 0 there is 1 root
b^2 -4ac <0 the root are complex
You use "Rise Over Run" to measure how steep a slope is or to discover whether a slope exists at all.
"Rise Over Run" can also be known as the "gradient", "slope" or "tangent".
Rise / Run = (y₂-y₁)/(x₂-x₁) = Opposite / Adjacent
These values can be positive or negative as positive and negative slopes exist in mathematics.
Answer:
C(50;-20)
Step-by-step explanation:
The question is asking for the midpoint of the line.
The triangle is formed by placing a line directly from the y-axis to the x-axis.
The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].
your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.
Your coordinates for B are (100;0)
C[(x1+x2)/2 ; (y1+y2)/2 ]
C [(0+100)/2 ; (-40+0)/2 ]
C[ 100/2 ; -40/2]
C (50 ; -20)
$1250
Use the formula i = prt
In this case, we don't know P or Principal amount
i = 400
r = .04 *found by diving 4/100*
n = 8
Set formula to solve for P like: P= i/r(n)
P=400/.04(8)
P= 400/.32
P = 1250
