pls help ( only the 4th ignore the other questions, you’ll need the line plot for 4 )
And pls don’t give me any zip files, just give me the answer

Answer:

Step-by-step explanation:

use the co-terminal idea Scarlett,  990° = 270 °.  You can see this just by looking at the picture.

Tan(270 ) = sin(270) / cos(270)  = -sin(90) / cos(90)   so now we know that Tan(270) is one of the non-existant angles b/c  cos(90) = 0 and that would mean that we have some number over 0... and then the universe blows up.. like my calc II professor liked to say  :| I think he was being a bit dramatic. :P anyway,  you want answers not long boring stories.. :D   so Tan(270)           DNE  ( does not exist )

If we were to look at a graph of Tan  , we'd see that at 270° or 3[tex]\pi[/tex]/2 ,  Tan runs off to infinity.   So there isn't a number to represent it.  :/    I'm attaching a picture of the  graph

notice in the graph, that when tan gets to 3/2,  it's running off to infinity ??

Answer:

Horizontal

Step-by-step explanation:

The mathematical definition of slope is very similar to our everyday one. In math, slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run.

Answer:

Step-by-step explanation:

Step 1. (The capture) Capture a sample  total counted =958, and them back tagged counted=38,total tagged=56

The idea is to estimate the proportion p = m/N of tagged =102.

Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged.

It is reasonable that, k/n would be a good estimante for p = m/N.

Accordingly, for an estimate N of N, se solve the equation m/N= k/n.

Step-by-step explanation:

[tex]a_n=a_1+d(n-1)\\\\\\10-6=4 \ \ and\ \ 14-10=4\quad\implies\qquad d=4\\\\a_1=6\\\\\\a_{30}=6+4(30-1)=122[/tex]

Answer:

No.

Step-by-step explanation:

Y=2x goes up twice and to the right once, it passes through the origin, therefore it won't touch or go pass by point (2,1)

Yes. You have to include 0.

If we round off this value to 2 decimal places then it is

0.03

Reason: after decimal point or before decimal point if you have to drop some digits and if the digit to be droped are 5 followed by non zero digit then previous digit is increased by 1.

Here, the digits to be droped are 5 and 4 after 0.02 so we increase 2 by 1 that is 3.

Answer:

Step-by-step explanation:

The zeros of the graph are x = - 4 and x = 2 , then the factors are

(x + 4)(x - 2) and

y = a(x + 4)(x - 2) ← a is a multiplier

To find a use any other point on the graph and substitute into the equation

Using (0, - 8 ) , then

- 8 = a(4)(- 2) = - 8a ( divide both sides by - 8 )

1 = a

y = (x + 4)(x - 2) = x² + 2x - 8

with b = 2 and c = - 8

The graph is increasing from the turning point ( vertex) to the right

vertex = (- 1, - 9 )

Increasing in the interval [- 1, ∞ )

Answer:

0.000036

Explanation:

When multiplying a number by 10 to the power of a positive exponent (e.g.  

10

3

), move the decimal in the number that many spaces to the right (e.g.  

4.5

⋅

10

3

=

4500

).

When multiplying a number by 10 to the power of a negative exponent (e.g.  

10

−

4

), move the decimal in the number (the absolute value of) that many spaces to the left (e.g.  

4.5

⋅

10

−

4

=

0.00045

).

For  

3.6

⋅

Answer:

18

Step-by-step explanation:

8n=144

divide the both side of the equation by 8

and you will get

n=18

Answer:

8n-5=139

Add 5 to each side.

8n=144

Divide each side by 8.

n=18

Answer:

m = 56

Step-by-step explanation:

.3m = 16.8

3m = 168

m = 168/3

m = 56

Answer:

x=65°  

Step-by-step explanation:

Since all exterior angles add up to 360°.

⇒(3x+25°) + (20°) + (x+55°) =360°

⇒4x+100°=360°                                      {Add up like terms}

⇒4x=260°                                                {Subtract 100 from both sides}

∴  x=65°                                                   {Isolate x (divide both sides by 4)}

I hope this helped you with your math problem but more especially with understanding how to solve.
