Story Problem Solving by Min and Max
To start off I I'm trying to find what T is so I put it into the equation (x=-b/2a) from ax^2+bx+c so i put it in as x=30/10 and I got x to be 3 so i plugged it in as -5(3)^2+30(3)+10 I solved it and got 145 for the max.
Story Problem Solving by Finding Zeros
To start i factored out 16 and got the problem to be -t^2+6t+7 then I put it into the T chart and tried to find multiplied to be -7 and added up to be a +6. Those number were (7 and -1) I plugged those numbers into my equation and the new equation was (-t^2+7t)(-1t+7) then I factored out a t from the first parentheses and a positive 1 from the second parentheses and got the final answer to be (t+1)(-t+7) then set them both equal to zero and the answers were t=-1 and t=-7
Solving Complex Numbers
Addition
combine like terms, add, and solve
Subtraction
combine like terms, subtract, and solve
Foil
multiply the first number times the numbers in the parentheses then multiply the second number times the parentheses, combine like terms, and solve
Dividing
multiply the top and bottom X -3i substitute the i^2 for a -1, plug in, solve, and reduce
Multiplication
multiply the top and bottom X 2-3i substitute the i^2 for a -1, plug in, and solve
Vertex Form
The vertex was (1,3) so i plotted that point onto my graph then the -2 in front of the parentheses showed me that the other points were going to be down 2 and over one
Standard Form
plug into T chart, find the points for X and Y, and solve by plugging it in a graph
