Answer:

a. f(x) is continuous for all real numbers

Step-by-step explanation:

At x = 1

Piece 1:

f(x) = 1² + 4 = 5

Piece 2:

f(x) = 1 + 4 = 5

First piece ends at (1,5)

Second piece starts at (1,5)

So no discontinuity

Answer:

The survey is meaningless because of nonresponse bias.

Step-by-step explanation:

The sample who responded (567) is less than half of Hayden's blog readers (1200). So, in this case, the results were really invalidated, because of the great absence of response, and the survey cannot be taken seriously at least statistically speaking.

567---100

x------35

x≈199 people said No

The bases of the prism below are right triangles. The volume of the prism is 3360 units33 . Find the height of the prism.
lana66690 [7]

Answer:

14

Explanation:

Given:

Volume of the prism = 3360 units^3

To find:

The height of the prism

We'll use the below formula to determine the height(h) of the prism;

\begin{gathered} Volume(V)=Area(A)\text{ of the triangular base * Height\lparen H\rparen of the prism} \\ V=(\frac{b*h}{2})*H \\ 3360=(\frac{16*30}{2})*H \\ 3360=240*H \\ H=\frac{3360}{240} \\ H=14 \end{gathered}

So the height of the prism is 14
