Which quadratic function has a vertex point of (3,5) and passes through the<br> point (-2,55)?
Alex17521 [72]

9514 1404 393

Answer:

  f(x) = 2(x -3)² +5

Step-by-step explanation:

For vertex (h, k) and scale factor 'a', the vertex form is ...

  f(x) = a(x -h)² +k

We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.

  55 = a(-2 -3)² +5

  50 = 25a . . . . . . . . subtract 5

  a = 2 . . . . . . . . . . . divide by 25

So, the function is ...

  f(x) = 2(x -3)² +5

__

In standard form, that will be ...

  f(x) = 2x² -12x +23

iren2701 [21]
The way I would look at it is that Sophia types 15 words per minute faster than Patty so every minute Sophia is 15 minutes closer to what Patty has done. 510/15=34 so after 34 minutes Sophia will have caught up to Patty

The glasers had $317 in their checking account. They wrote checks for $74, $132, and $48. What is their checking account balance
Masja [62]
To solve this, you would first add the amount of the 3 checks they wrote together. So, 74+132+48=254. Then, we know that they had $317 in their checking account. Now, you would take the amount they had in their account (317), and subtract it by the total of the 3 checks they wrote (254). 

The checking account balance is 317-254=63, so $63 is their checking account balance.

I really hope this helps you.
