Which statements describe the graph of y = Negative RootIndex 3 StartRoot x minus 1 EndRoot + 2? Select three options.

SOVA2 [1]

Answer:

The graph has a domain of all real numbers.

The graph has a y-intercept at $(0,1)$ .

The graph has an x-intercept at $(-7,0)$ .

Step-by-step explanation:

Given: The graph is $y=\sqrt[3]{x-1}+2$

The domain of a function is a set of input values for which the function is real and defined.

Thus, the graph has a domain of $(-\infty, \infty)$ .

To find the y-intercept: To find the y-intercept, substitute $x=0$ in $y=\sqrt[3]{x-1}+2$ .

$\begin{aligned}y &=\sqrt[3]{x-1}+2 \\&=\sqrt[3]{0-1}+2 \\&=-1+2 \\&=1\end{aligned}$

Thus, the y-intercept is $(0,1)$

To find the x-intercept: To find the x-intercept, substitute $y=0$ in $y=\sqrt[3]{x-1}+2$ .

$\begin{aligned}y &=\sqrt[3]{x-1}+2 \\0 &=\sqrt[3]{x-1}+2 \\-2 &=\sqrt[3]{x-1} \\(-2)^{3} &=(\sqrt[3]{x-1})^{3} \\-8 &=x-1 \\-7 &=x\end{aligned}$

Thus, the x-intercept is $(-7,0)$

The faces of a rectangular solid are square.<br> always<br> sometimes<br> never

Sonja [21]

Answer:

sometimes

Step-by-step explanation:

We can consider the example of a cuboid.

It is a rectangular solid whose all faces are made of rectangles.

But if we will consider a example of cube; which is also a kind of rectangular solid whose all faces are made up of square.

so we can get some solids whose faces are other than squares as well and some whose faces are squares.

Hence, we could say that:

The faces of a rectangular solid are sometimes square.

The figure shows a flagpole and its shadow. The shadow has a length of 43 feet and the sun's rays make an angle of 30° with the

Nataliya [291]

Answer:

B, 25 ft

Step-by-step explanation:

This can be modeled as a triangle. Let x be the height of the flagpole. From the picture, we can see that tan30 = x/43. x = 43tan30 = 25 ft.
