Answer:
-2
Step-by-step explanation:
- Get the equation in the form y = ax2 + bx + c.
- Calculate -b / 2a. This is the x-coordinate of the vertex.
- To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
One: false
two: false
three: true
I think the answer would be 16 and 13
Answer:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Step-by-step explanation:
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
Cot (B) = Cos(B) / Sin(B)
Cot B * Sin B = cos(B) / Sin(B) * Sin(B) = Cos(B)
Answer: Cos(B)
