Answer:
6
Step-by-step explanation:
since this is on a graph, and perfectly lined up, you can just count the squares on the length of XY
A, B, C, D form a complete circle which is 360 degrees.
Add all 4 together:
A + 2A + 4A+ 3A = 360
10A = 360
Divide both sides by 10:
A = 360/10 = 36
Now we know A so can calculate the rest:
B = 2A = 2(36) = 72 degrees
C = 4A = 4(36) = 144 degrees
D = 3A = 3(36) = 108 degrees
Answer:
If your quadratic equation it is in the form of x^2+bx+c=0 (in other words, if the coefficient of the x^2 term=1), it's possible (but not guaranteed) that a relatively simple shortcut can be used to factor an equation. Find two numbers that both multiply to make C and add to make B.

Answer:
Umbrellas cause rainstorms.
Step-by-step explanation:
Due to all the others being correct, that means this is incorrrect, there are no umbrellas that cause rainstorms.
Standard quadratic equation .. y = a x^2 + b x + c
<span>parabola 'a' not equal to zero </span>
<span>a<0 parabola opens downward </span>
<span>a>0 parabola opens upward </span>
<span>when |a| >>0 the parabola is narrower </span>
<span>when |a| is close to zero , the parabola is flatter </span>
<span>when the constant is varied it only effects the vertical position of the parabola , the shape remains the same</span>
