What are the coordinates of the vertex of the parabola described by the equation below? y=7(x+5)^2-4

Ipatiy [6.2K]

Answer:

$y= 7(x+5)^2 -4$

The vertex form for a parabola is given by this expression:

$y = a(x-h)^2 +k$

By direct comparison we see that for this case:

$a = 7, h = -5 and k=-4$

And we know from the general expression that the vertex is:

$V= (h,k)$

So then the vertex for this case is:

$V= (-5,-4)$

Step-by-step explanation:

For this case we have the following function:

$y= 7(x+5)^2 -4$

And we need to take in count that the vertex form for a parabola is given by this expression:

$y = a(x-h)^2 +k$

By direct comparison we see that for this case:

$a = 7, h = -5 and k=-4$

And we know from the general expression that the vertex is:

$V= (h,k)$

So then the vertex for this case is:

$V= (-5,-4)$

<u>Figure - 1</u> :

Let the missing side as " n "

$\mathrm{ \triangle DEF \sim \triangle DRQ}$

Therefore the sides will be proportional,

$\dfrac{n}{9} = \dfrac{4}{12}$

$n = \dfrac{1}{3} \times 9$

$n = 3 \: \: units$

_____________________________

<u>Figure - 2</u> :

Let the missing side as " m "

The Triangles are similar, therefore their sides will be proportional.

$\dfrac{m}{8} = \dfrac{9}{6}$

$m = \dfrac{3}{2} \times 8$

$m = 3 \times 4$

$m = 12 \: \: units$

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.

mafiozo [28]

Answer:

AD = 7

Step-by-step explanation:

Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.

We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD

We can solve the problem by solving for x:

$\frac{x}{32} =\frac{21}{24}$

Cross multiply.

$24x = 672$

Simplify.

$x=28$

Subtract the value of DB to find AD.

$28-21=7$

$AD=7$
