Find the values of y = r(x) = ∛x for
marissa [1.9K]
\bf y=r(x)=\sqrt[3]{x}\quad x=
\begin{cases}
-2.197\\
-1.331\\
0\\
1.331\\
2.197\\
3.375\\
4.913
\end{cases}\implies y=
\begin{cases}
\sqrt[3]{-2.197}\\
\sqrt[3]{-1.331}\\
\sqrt[3]{0}\\
\sqrt[3]{1.331}\\
\sqrt[3]{2.197}\\
\sqrt[3]{3.375}\\
\sqrt[3]{4.913}
\end{cases}

so.. .get the pair and plot them then, all you need is your calculator to get the cubic root of the provided value.

What are the solutions of the quadratic equation 49x2 = 9?
pishuonlain [190]
49x^2 - 9 = 0
As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:
49 = 7^2
9 = 3^2
x^2 = (x)^2
so...
(7x - 3)(7x + 3) = 0
7x - 3 = 0 7x + 3 = 0
x = 3/7 x = -3/7

In the city of Carmen, there is a drawbridge that is opened twice per hour over the summer. The graph below shows the number of
n200080 [17]

Answer:

1) Between 0 and 1 minute the rate of change is 25 ft./min

2) Between 1 and 2 minute the rate of change is 0 ft./min

3) Between 2 and 4 minute the rate of change is -12.5 ft./min

Step-by-step explanation:

1) Between 0, and 1 feet, we have;

The rate of change = (Final height - Initial height)/(Final time - Initial time)

The rate of change = (40 - 15)/(1 - 0) = 25 ft/min

Between 0 and 1 minute the rate of change = 25 ft./min

2) Between 1, and 2 feet, we have;

The rate of change = (40 - 40)/(2 - 1) = 0 ft/min

Between 1 and 2 minute the rate of change = 0 ft./min

3) Between 2, and 4 feet, we have;

The rate of change = (15 - 40)/(4 - 2) = -12.5 ft/min

Between 2 and 4 minute the rate of change = -12.5 ft./min
