The ratio of areas is the square of the scale factor, so that factor is
√(320/180) = 4/3
Answer:
$5.71
Step-by-step explanation:
20-5.88=14.12
14.12-8.41=5.71
vertex = (3,- 5 )
given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
the x-coordinate of the vertex is
= -
y = x² - 6x + 4 is in standard form
with a = 1, b = - 6 and c = 4, hence
= - = 3
substitute this value into the equation for y- coordinate
y = 3² - 6(3) + 4 = 9 - 18 + 4 = - 5
vertex = (3, - 5 ) → second table
I think you would put 570 in the blank since 19 x 3 = 57
First calculate
.
We take positive value of sinθ because 0° < θ < 90°
Now we could calculate sin2θ, cos2θ and tan2θ:
