What is h(x) = 7+ 10x + x2 written in vertex form?
Roman55 [17]

Answer:

h(x) = (x+5)^{2} -18

Step-by-step explanation:

-b/2a is the formula to find the vertex's x coordinate.

-10/2(1) = -5 and "(x+5)" represents a translation to the left 5 units, so that must be the answer

Do these ratios make a proportion? 4:10 and 6:15<br><br> I NEED THIS ASAP!!! Thanks!
Sonbull [250]

To see if these ratios make a proportion let us first change them into fractions

= 4:10 = 4/10 = 4 ÷ 2 / 10 ÷ 2 = 2/5

= 6:15 = 6/15 = 6 ÷ 3 / 15 ÷ 3 = 2/5

= Since both these ratios are getting simplified into a same fraction , they are proportional .

Therefore , 4 : 10 :: 6 : 15 ( 4 : 10 is proportional to 6 : 15 )

Find the missing lengths of the sides.
Ulleksa [173]

Answer:

The second bubble

Step-by-step explanation:

In a 30 60 90 triangle as shown here a is always 1/2 the hypotenuse (Which the hypotenuse is 6) and then just add \sqrt{3} to the end of it to get b

<em>So, lets demonstrate</em>

a = 1/2 * 6 = 3

b = a*\sqrt{3} = a\sqrt{3} = 3\sqrt{3}

So,

a = 3

b = 3\sqrt{3}
