Lucas is selling ribbons to raise money for the Juvenile Diabetes Research Foundation. His expenses include $23 for materials, p
Tanzania [10]

Using the equation, the amount of ribbon she needs to sell to break even is 50 ribbons.

<h3>How to represent system of equation and solve?</h3>

x = number of ribbons

y = expenses or revenue

Therefore, the system of equation for this situation is as follows;

y(expenses) = 23 + 0.04x

y = 23 + 0.04x

He charges $0.50 per ribbon. Therefore,

y(revenue) = 0.50x

y = 0.50x

Therefore, for her to break even,

23 + 0.04x = 0.50x

23 = 0.46x

x = 23 / 0.46

x = 50

Therefore, she needs to sell 50 ribbons for her to break even.

Task 1:
laiz [17]

Answer:

The toy's maximum height is 10.12\ \text{feet}.

Step-by-step explanation:

The equation that models the toy's height in feet from the ground at t seconds after  he threw it is given by :

h = -2t^2 + 7t + 4 .....(1)

It is required to find the toy's maximum height. For maxima or minima, put

\dfrac{dh}{dt}=0

Plugging the value of t in above equation,

\dfrac{d(-2t^2 + 7t + 4)}{dt}=0\\\\-4t+7=0\\\\t=\dfrac{7}{4}\\\\t=1.75\ s

Now put t = 1.75 s in equation (1) such that,

h = -2(1.75)^2 + 7(1.75) + 4\\\\h=10.12\ \text{feet}

So, the toy's maximum height is 10.12\ \text{feet}.
