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

A square has an area of 144 sq. units. how long is its perimeter?
Arada [10]
Formula for Area of a square:

\boxed {\boxed {\text {Area = Length x Length}}}

Given that the area is 144 unit²:

\text {Length}^2 = 144

\text {Length} = \sqrt{144} = 12 \text { units}

Formula for Perimeter of a square:

\boxed {\boxed {\text {Perimeter = 4 x Length }}}

\text {Perimeter = } 4 \times 12 = 48 \text { units}


\boxed { \boxed { \text {Answer: The perimeter is 48 units.}}}

= 35.20 * 1/4
multiply numerators

= (35.20 * 1)/4

=35.20/4
divide

= $8.80

Which equation is represented by the graph below?
gregori [183]

Answer:

y = e^x - 4

Step-by-step explanation:

The missing options are

y = ln x - 3

y = ln x - 4

y = e^x - 3

y = e^x - 4

The function is defined in quadrant 3 and increases exponentially, then it is not a logarithm.

f(x) crosses the y-axis at (0, -3). Replacing x = 0 the last option, we get:

y = e^0 - 4 = 1 - 4 = -3
