Answer:

To find the maximum of a function in ax^2 + bx + c form, you can use  the formula: maximum = c - (b^2 / 4a).

In this question, a = -16, b = 180, and c = 63.

Maximum = 63 - (180^2/4(-16))

Maximum  = 569.25

Finally, rounding this to the nearest tenth of a foot, the final answer is 569.3 ft.

Let me know if this helps!

Talking to Your Parents

Sure, you talk to your parents, but what if you need to really talk? Maybe you have a problem you can't solve alone. Or it could be that you want to feel closer to your Mom and Dad.

It's easy to say "Hi, Mom" or "Dad, can you pass the potatoes?" It can be harder to start talking about personal topics. Still, it's good to confide in your parents. In fact, it can help a lot.

Be Brave and Start Talking

Let's face it, talking about personal stuff can feel embarrassing. But remember, your parents know you pretty well — and they were your age once, too! So don't let a little embarrassment stop you. It's OK to go ahead and share what's on your mind.

Some kids might think if they share a problem, they'll make a parent worried or upset. But your mom or dad can handle knowing about your problem, big or small. If they look concerned, it just means they care, and that they feel for you.

Here's how I like to represent this:

Randy = 7

Randy * 2 = Ann

Ann + 3 = Janet

Janet + 5 = Donald


If we go along and fill in the blanks for each equation, we do this:

7 * 2 = 14

14 + 3 = 17

17 + 5 = 22

So Donald solved 22 problems.


Hope this helps!

Which expression gives the distance between the points (4,6)and (7,-3)
amid [387]
The distance between any two points is:

d^2=(x2-x1)^2+(y2-y1)^2 so in this case:

d^2=(7-4)^2+(-3-6)^2

d^2=3^2+9^2

d^2=90

d=√90

d=3√10 units 

d≈9.49 units (to nearest hundredth of a unit)
