Answer:
a. Vertex = (2.5,-12.25)
b. y-intercept = (0,-6)
c. x-intercept = (6,0) ; (-1,0)
Step-by-step explanation:
a.
Your equation is written as:
The easiest way to find the vertex is writing the equation this way:
Being the vertex (h,k)
So first complete the square
Vertex : (2.5,-12.25)
b.
To find the y-intercept you need to replace the equation when x = 0 and get y
c.
To find the x-intercept you need to replace the equation when y = 0 and get x
(a) The team captain wants to know what his teammates eats before a match
Team captain know by taking a survey of teammates
(b) The team captain wants to know who can score most goals against the best player
This can be known by observation of games. so its observational study
(c) The team captain wants to know how praising the affects the teammates performance.
This can be known by experiment
(d) The team captain wants to know what other sports teammates play
This can be known by observation of games. so its observational study
Answer:
yes
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is a fascinating question. It turns out to be true because of the relationship between a 30 degree angle and a 60 degree angle
The answer is that the product of sin30*sin60 = cos(30)*cos(60). This happens because sin(60) = cos(90-60) = cos(30)
Other angles will do the same thing sin36 * sin54 = cos(54)*cos(36)
