Answer:

The length of side b is 9.

Step-by-step explanation:

Triangles are similar if they have the same shape, but can be different sizes.

When two figures are similar, the ratios of the lengths of their corresponding sides are equal.

If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. We know that the triangle $ABC$ is similar to the triangle $XYZ$ . Therefore the following relation must be true:

$\frac{AB}{AC} =\frac{XY}{XZ}$

We know that side $AB$ is equal to 8, side $AC$ is equal to b, side $XY$ is equal to $2\frac{2}{3}$ , and side $XZ$ is equal to 3.

Substituting these values into the above relation and solving for b we get that:

$\frac{8}{b} =\frac{2\frac{2}{3} }{3}\\\\\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 2\frac{2}{3}=\frac{8}{3}\\\\\frac{8}{b}=\frac{\frac{8}{3}}{3}\\\\8\cdot \:3=b\frac{8}{3}\\\\24=b\frac{8}{3}\\\\8b=72\\\\b=9$

Find the vertex of y = x2 + 14x − 40 by completing the square. A. (−7, 89) B. (−89, −7) C. (7, 89) D. (−7, −89)

irga5000 [103]

Alright, lets get started.

$y = x^2 + 14 x - 40$

For making complete square, we will add and subtract 49 in this

$y = x^2 + 14 x - 40 + 49 - 49$

$y = x^2 + 14 x + 49 -40 - 49$

$y = (x+7)^2 - 40 - 49$

$y = (x+7)^2 - 89$

Comparing the standard equation of parabola

$y = a (x-h)^2 + k$ where (h,k) are vertex

So, comparing the equation with standard one, h, k would be = (-7 , -89)

So, the vertex are (-7 , -89) : Answer

Hope it will help :)

Why is baseball in all its forms – from T-ball to the major leagues – important to Americans of all ages?

Svetllana [295]

Baseball is a fun sport with a lot of history in the USA. Many families show their kids about baseball and that is how they start to like it. It gets passed on. But sports in general help you understand yourself. You get to be free and like what team you want, on play the way you want. There are many ways to understand yourself from sports
