Answer:
diameter = 12
circumference = 37.68
Step-by-step explanation:
diameter: d=2r 2 * 6 = 12
circumference = 2 x π x radius (π =3.14) 2 * 3.14 * 6 = 37.68
The graph of a quadratic function y = ax² is a VERTICAL parabola open upward or downward depending whether a (the coefficient of x) is positive or negative
The graph y² = ax or y = √ax is a HORIZONTAL parabola open to the right or to the left depending whether a (the coefficient of x) is positive or negative
The answer is A/the first one, I hope this helped
Answer:
x = 2.5.
y = 5.
Step-by-step explanation:
As they are image and pre-image of a dilation they are similar triangles, so the corresponding sides are in the same ratio.
4/2 = 5/x
2 = 5/x
2x = 5
x = 2.5.
Also:
4/2 = (y + 1)/ 3
2 = (y + 1) / 3
y + 1 = 6
y = 5.
$180 taken away from $450 is $220. the rest i'm not quite sure because there wasn't a given price for the music.
