Answer:
B
Step-by-step explanation:
the sum of the roots = - 
x² + 6x - 55 = 0
with a = 1 , b = 6 , then
sum of roots = - 
= - 6

Answer:
45) 35.75 sq km
46) 24.5 sq km
Step-by-step explanation:
Area of Square:
A= 
45) A = (11)(6.5) ÷ 2 =
46) A = (10)(4.9) ÷ 2 =
Cashew: raisin 2:4 or 1:2
Chocolate: peanut 3:6 or 1:2
So it is chocolate to peanuts
period = 2, Amplitude = 2
AMPLITUDE
---------------------------------
f(t) = sin(t) , this function has an amplitude of 1 , because its y values goes one unit up, and one unit down from the x axis. to increase this to an amplitude of 2, we get f(t) = 2. sin(t). This means the graph is twice as tall as our original function f(t) = 1.sin(t).
PERIOD
----------------------------
the period has a formula: w = 2pi / |B | . The normal period for a sinewave
f(t) = sin(t) = 2 pi.
So in our new function f(t) = 2 sin (t) [ amplitude is now multiplied by 2], the period (as stated in the question) is 2, that is 2 pi (remember the formula for period stated 2pi) divided by b, which is now 2. Which means 2pi is now divided by 2 or multiplied by 1/2. 2pi /2 = pi or 1/2 x 2pi = pi. so as you increase the period in the equation, the sinewave becomes shorter.
ANSWER
------------------------------
So the function is actually f(t) = 2.sin(2t).
