Substitution.

Here is an example.

Let x be equal to 3 and y equal to 3.

x=3, y=3

From this we can conclude that the values of both x and y are equal to three therefore x and y have the same value and are equal.

x\wedge y=3\Longrightarrow x=y

Here in your case we have:

AB=1, BC=1 \\AB\wedge BC=1\Longrightarrow AB=BC

Hope this helps.

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
