What is the value of x?

alina1380 [7]

Answer:

Step-by-step explanation:

Look at the picture.

We have the triangles 30° - 60° - 90° and 45° - 45° - 90°.

The sides are in proportions:

30° - 60° - 90° ⇒ 1 : √3 : 2

45° - 45° - 90° ⇒ 1 : 1 : √2

======================================================

$SR=ST\sqrt3\to ST\sqrt3=2\sqrt3\qquad\text{divide both sides by}\ \sqrt3\\\\ST=2\\\\TR=2ST\to TR=2(2)=4\\\\RQ=TR\to RQ=4\to x=4$

I don't know how to simplify this ratio - 3/4 : 2/3 : 1 : 1

saw5 [17]

$- \frac{3}{4} : \frac{2}{3} : 1: 1 \\ \\ multiply \: all \: with \: 12 \\ \\ = 12 \times( - \frac{3}{4} ) : 12 \times \frac{2}{3} :12 \times 1: 12 \times 1 \\ \\ = - 9 : 8 : 12: 12$

$\textbf{\blue{The simplified ratio is:}}\\ \\ \boxed{ \textbf{\red { \huge{-9:8:12:12}}} }$

The parabola y=x^2 is reflected across the x-axis and then scaled vertically by the factor of 1/8. What is the equation of the n

poizon [28]

Answer:

y = (-1/8)x^2

Step-by-step explanation:

Start with y = x^2. When the original parabola has been reflected across the x-axis, the pertinent equation becomes y = -x^2.

Now if this is scaled vertically by a factor of 1/8, we get:

y = (-1/8)x^2
