If she wants to frame a square painting with an area of 400 square inches, all you would have to do is to find the square root of 400, which is 20. Thus, each side is 20 inches long. 

If you have to set an equation up, it would simply be:

x= \sqrt{400}

Artemon [7]

Step-by-step explanation:

f(x) = 3x⁴ - 5x² + 2x - 3

When x = -1,

f(-1) = 3(-1)⁴ - 5(-1)² + 2(-1) - 3 = 3 - 5 - 2 - 3 = -7.

The balloon reaches a height of 7 feet at 0.1 seconds and 2.13 seconds

<h3>How to determine the time the balloon is at the height?</h3>

The equation of the function is given as

h(t)= -16t^2 + 35t + 5

The above equation is a quadratic equation

When the balloon is at a height of 7 feet, we have

h(t) = 7

So, we have the following equations

h(t)= -16t^2 + 35t + 5

h(t) = 7

Next, we plot the equations on a graph (see attachment)

The equations intersect at

t = 0.059 and t = 2.129

Approximate

t = 0.1 and 2.13

Hence, the times are 0.1 seconds and 2.13 seconds
