(Remember to use the 5 steps for solving two-step equation word problems!) | 1. ... Joe went to the hobby shop and bought 2 model sports cars at $8.95 each and some paints.
Step-by-step explanation:
Answer:
Move everything so all terms are on one side of the = sign, and solve for zero using the Quadratic Formula. There are two answers: v=7±√69
10
Step-by-step explanation:
Subtract 1 from both sides so you have
e "standard form" of a quadratic is
, so first we have to identify a, b, and c in your equation: a=5, b= -7, and c= -1.
The quadratic formula is
. Plugging in your values, we get
−
. It looks a little funny, but you can't simplify it any more. You can check the answer by graphing the function on your calculator and asking for the function value at these points.
After graphing, hit 2nd, "Calc", "Value" on your TI, and type in either
, and you'll get that
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>
➷ Just work with what is inside the parenthesis
Also, move around the terms to help it make more sense:
(cosA cosB - cosA cosB + sinA sinB + sinA sinB)
As you can see, the 'cosA cosB' would cancel out through subtraction.
Now we have this:
(sinA sinB + sinA sinB)
This is just two sets of sinA sinB so it can be written as:
(2 * sinA sinB)
Simply place the values outside the parenthesis back there to get the answer
SinA sinB = 1/2 * (2 * sinA sinB)
