PLZ DON'T TROLL ACTUALLY ANSWER THE QUESTION CORRECTLY ALGEBRA 1 QUESTION

Ingrid hit a golf ball. The height of the ball (in meters above the ground) t seconds after being hit is modeled by

h(t)=-5t^2+30t

1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation.

2) How many seconds after being hit does the ball reach its highest point?

seconds

Step-by-step explanation:

If we're looking for the point at with the ball reaches its highest point, we want to find the graph's vertex. In order to get the equation into a form with the vertex in it, we need to convert the equation into vertex form. This is an equation in the form , h being the x value of the vertex, and k being the y value of the vertex.

In order to convert our equation, into vertex form, we can algebraically manipulate it to get it into the form we want.

Therefore, our equation with the vertex in it is . To find the vertex, we can examine the equation to find the values of h and k in the formula   (where the vertex coordinates are (h, k)).

It seems that h is 3 and k is 45. Therefore, the coordinate of the vertex is (3, 45). Since it asks for how many seconds after being hit does the ball reach its highest point, we would take the x value since x represents seconds. This is 3. Therefore, the ball reaches its highest point after 3 seconds.

Hope this helped!

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
