I will be glad to help you in the comments. I do need to know though, what is the class this is presented in? Is this algebra, or calculus? Depending on the class, we have different approaches.

The height, in feet, of an arrow shot from a bow in an upwards direction, is modeled by the function h(t) = -16t2 + 96t + 5, whe

AnnZ [28]

Given function: h(t) = -16t^2 + 96t + 5, where t represents the time in minutes.

We need to find the interval for which the arrow is going up.

The arrow is going up would be the values of time t =0 when it start and when it went to highest point.

<em>Given function is a quadratic function and it represents a parabolic shape.</em>

<em>The highest point on the parabola is a vertex point.</em>

Therefore, we need to find the x-coordinate of the vertex.

We know, formula for x-coordinate of the vertex is

$\frac{-b}{2a}$

For the given quadratic a= -16 and b=96.

Plugging values of a and b in formula, we get

$\frac{-96}{2(-16)}=\frac{-96}{-32} = 3.$

Therefore, after 3 seconds arrow would be at maximum height.

Therefore, the interval for which the arrow is going up is [0,3].

Step-by-step explanation:

x+x+2+x+4=90

3x=84

x=28(first integer)

28+2=30(second)

To find this, first we subtract the extra 3 feet from the original 27 feet.
27-3=24
Then, we divide the left over length by three. This will provide us with the length for the shorter piece.
24/3=8
The shorter piece will be 8 feet long.
Now, we double that to find the longer piece without the additional 3 feet.
8x2=16
And we add those two (8 and 16) together to make sure it is equal to the 24 we divided into 3 earlier.
16+8=24
Now all that's left is to add the extra 3 feet to the 16 feet.
16+3=19
And add that to the 8 feet, to check to make sure the lengths add up to our original 27 feet.
19+8=27
Therefore, the two pieces are the following lengths:
Shorter piece: 8 feet
Longer piece: 19 feet
