Esi says that the value of z when z^2 = 80 does not belong in either of these categories since z must be greater than 8.
Anettt [7]

Answer:

9

Step-by-step explanation:

if z=8 then z^2 would be 64, which is not equal to 80

iz z=9 then z^2 would be 81, which is closer to 80 than 64

therefore, 9 is the whole number than z would be closest to

Please select the best answer from the choices provided<br><br> A<br> B<br> C<br> D
SSSSS [86.1K]
ANSWER

The correct answer is D.

\sum_{n=1} ^{6} (n - 3) = ( - 2) + ( - 1) + (0) + (1) + (2) + (3) = 3

EXPLANATION

The given expression is

\sum_{n=1} ^{6} (n - 3)

The symbol means summation.

So we need to substitute

n=1,n=2,n=3,n=4,n=5, \:and\:n=6

into the formula and add all to get,

\sum_{n=1} ^{6} (n - 3) = (1 - 3) + (2 - 3) + (3- 3) + (4 - 3) + (5 - 3) + (6 - 3)

We simplify to obtain,

\sum_{n=1} ^{6} (n - 3) = ( - 2) + ( - 1) + (0) + (1) + (2) + (3) = 3

The correct answer is D

Using complete sentences, explain the key features of the graph of the tangent function.
Temka [501]

Answer:

We are given the tangent function f(x)=\tan x.

Firstly we know that, \tan x=\frac{\sin x}{\cos x}, where \sin x is the sine function and \cos x is the cosine function.

Now, tangent function will be zero when its numerator is zero.

i.e. \tan x=0 when \sin x=0.

i.e. \tan x=0 when x=n \pi, where n is the set of integers.

So, tangent function crosses x-axis at n \pi, n is the set of integers.

Further, tangent function will be undefined when its denominator is zero.

i.e. \tan x=0 when \cos x=0.

i.e. \tan x=0 when x=(2n-1) \frac{\pi}{2}, where n is the set of integers.

Moreover, a zero in the denominator gives vertical asymptotes.

So, tangent function will have vertical asymptotes at (2n-1) \frac{\pi}{2}, n is the set of integers.

Therefore, these key features gives us the graph of a tangent function as shown below.
