Answer:
Quadrant II
Step-by-step explanation:
(-5,6)
The x coordinate is negative so the quadrant is either 2 or 3
The y coordinate is positive so the quadrant is either 1 or 2
To make both happen, it must be in quadrant 2
Quadrant II
Answer:
Company C!
Step-by-step explanation:
In order to see which company has the best buy we have to see the amount each company sells for one stuffed mascot. In order to do this we have to divide .
Company A:
Company A sells 16 lions for $44.32 this is the same as 1 stuffed lion for $2.77.
Company B:
Company B sells 18 lions for $50.22 this is the same as 1 stuffed lion for $2.79.
Company C:
Company C sells 12 lions for $32.88 this is the same as 1 stuffed lion for $2.74
Thus as you can see the company with the best buy is company C.
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
You know the triangle has a base of 6 meters, and that the formula to find the area of a triangle is 1/2bh or one-half of the base times the height. So, you would plug in 9 meters squared=one half of six times h, or 9m^2=1/2(6)*(h). In simplifying this, you would get 3h=9m^2. Divide both sides by three and get h=3. Hope this helps, and if you need any further explanations, please let me know!
