Answer:
exact form x = 2/e^2 decimal form is x = 0.27
Step-by-step explanation:
H = -b / 2a = 2 : x coordinate of the vertex of the parabola k = -(2)2 + 4(2) + C = 4 + C : y coordinate of vertex x = (2 + √(4 + C)) , x = (2 - √(4 + C)) : the two x intercepts of the parabola. length of BA = k = 4 + C length of AC = 2 + √(4 + C) - 2 = √(4 + C) area = (1/2)BA * AC = (1/2) (4 + C) * √(4 + C) (1/2) (4 + C) * √(4 + C) = 32 : area is equal to 32 C = 12 : solve above for C.
Step-by-step explanation:
- 360_90_110=160
- 2a+3a=160
- a=32°
First you draw threes cookies, then you give a cookie to each child, then with the last cookie you split it in half and they each have 1 1/2 cookie.
Subtract 3 1/5 from both sides of the equation.
