Answer: 5
----------------------------------------------------------
On the curve, the highest point has a y coordinate of y = 6
The lowest point on the curve has a y coordinate of y = -4
Subtracting the y values gets us: 6 - (-4) = 6 + 4 = 10
Cut that result in half: 10/2 = 5
The amplitude is 5. This is the vertical distance from the midline (y = 1) to either the highest point or the lowest point.
If lauryn has purchased 4 books you have to do (2x-12)^4. Expand it to: (2x-12)(2x-12)(2x-12)(2x-12) multiply together. Then solve for x. If you need more help let me know.
Answer: full budget of 100% will be 1600
Step-by-step explanation:
If 75% = 1200
Full budget will be 100%
Represent the question as if 75% = 1200
Then 100% = x
Cross multiply:
75%x = 1200%
Divide both sides by 75%
x = 1200%/75%
x = 16 × 100
= 1600
Area of rhombus = 1/2 * diagonal * diagonal
72 = 1/2 * AC * BD
Diagonals bisect each other in a rhombus so if EC is 8 then AC is 16
72 = 1/2 * 16 * x - 1
72 = 8(x-1)
9 = x-1
X = 10
Check
72 = 1/2 * 16 * 10-1
72 = 1/2 * 16 * 9
72 = 8 * 9
72=72
