Answer:

0.4

Step-by-step explanation:

drawing a triangle with each side correspondent to each of its measurements all you are doing is dividing the side that you would want to find its scale factor of, which in this case you would take AB and DE and have AB/DE dividing that and getting 0.4 as its scale factor.

Solve for B A= 6B +C
dimulka [17.4K]

B = \frac{A - C}{6}

isolate 6B by subtracting C from both sides

A - C = 6B ( divide both sides by 6 )

B = \frac{A - C}{6}

Are the two parabolas defined below similar or congruent or both? Justify your reasoning. Parabola 1: The parabola with a focus
Dominik [7]

Answer:

They are similar by a factor of 14

Step-by-step explanation:

From the general equation of a parabola opening up (since the directrix is on the y axis and the focus is upwards this line) the focus coordinates are:

Focus = (h,k+p) = (0,2)

So h=0 and k+p=2, for the directrix:

y = k-p=-4

solving k and p from the two equations above:

k=-1 and p=3

So for Parabola 1 the equation would be:

x^{2} =4*3(y+1)

For Parabola 2 the general equation is:

x^{2} =4*(3/2)(y)

here h=0, k=0, p=3/2 so focus is (0,3/2), directix is y=-3/2, they have the same orientation.

they are not congruent. For them to be similar it must comply:

x_{1}=k x_{2}\\y_{1}=ky_{2} => (1/12)x_{1} ^{2} -1 = k(1/6)x_{2} ^{2}

replacing x_{1} and solving for k:

(1/12)(kx_{2}) ^{2} -1 = k(1/6)x_{2} ^{2}\\ (1/12)k^{2} x_{2}^{2}-1 = k(1/6)x_{2} ^{2}\\k-12 = (12/6)=2\\k = 2+12=14\\

They are similar by a factor of 14
