344 seconds

-9 seconds

-344 seconds

Answers

Answer 1

Answer: set this up as a proportion. 43 ft/ 1 sec to 387 ft/ x sec. Now cross multiply to get:

43x = 387

now divide by 43 on each side to get:

x = 9 sec

Hi!!

1) 2/3 *12
You basically do this
2/3 * 12/1 = 24/3 which = 8!

2) 13 * 1/2
= 13/1 * 1/2
= 13/2
= 6 1/2
Hope this helps!

Answers

So,

I will assume that you are adding 12.

16 - 7 - (-4) + 12

16 - 7 = 9
9 - (-4) + 12

9 - (-4) = 9 + 4 = 13
13 + 12

13 + 12 = 25

The correct option is C.

The function f(x)=x^2 -6x+3 is transformed such that g(x)=f(x-2). Find the vertex of g(x). (5,6)

(5,-8)

(1,-6)

(3,-8)

Answers

Answer:

$g(x) = (x-2)^2 -6(x-2) +3$

$g(x) = x^2 -4x +4 -6x +12 +3$

$g(x) = x^2 -10 x +19$

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

(5,6)

Step-by-step explanation:

We have this original function given :

$f(x) = x^2 -6x +3$

And we want to find the vertex for this new function $g(x) = f(x-2)$ and we have:

$g(x) = (x-2)^2 -6(x-2) +3$

And solving the square we got:

$g(x) = x^2 -4x +4 -6x +12 +3$

And adding similar terms we got:

$g(x) = x^2 -10 x +19$

Now we can complete the square like this:

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

The general equation is given by:

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

(5,6)

idk I think it is 53.33

It is 144.
6 x 8 = 48 (two identical triangles)
4 x 8 = 32
