Hello!

-EXPANDED FORM- To make the number 58.8 in expanded form, we start out with the number 50 and then add 8 ones to it and finally add .08

-WORD FORM- To make the number 58.8 in word form, the answer would be Fifty-Eight and Eight Tenths

(5 x 10) + (8 x 1) + (8 x 0.1)

50 + 8 + .8

Fifty-eight and eight tenths

Hope this helped!

Answer:

$y=-2\,(x+3)^2-3$

Step-by-step explanation:

Notice that they are asking you to write the equation of the parabola in vertex form, that is using the coordinates of the vertex $(x_v,y_v)$ in the expression:

$y-y_v=a\,(x-x_v)^2\\y=a\,(x-x_v)^2+y_v$

we can start by directly replacing the given vertex coordinates (-3, -3) in the expression, and then using the extra info on the point the parabola goes through in order to find the parameter $a$ :
