Find the exact value of each trigonometric function using the unit circle ​

Answers

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 ??

Answers

Answer:

Surface area of square pyramid = 380 m²

Step-by-step explanation:

Given:

Side of square base =10 m

Height of Square pyramid = 14 m

Find:

Surface area of square pyramid

Computation:

Surface area of square pyramid = Surface area of Base + 4[Surface area of triangle]

Surface area of square pyramid = [side x side] + 4[(1/2)(b)(h)]

Surface area of square pyramid = [10 x 10] + 4[(1/2)(10)(14)]

Surface area of square pyramid = 100 + 4[70]

Surface area of square pyramid = 100 + 280

Surface area of square pyramid = 380 m²

Does -6^2 = (-6)^2? Explain your answer.
PLEASE HELP!!!!!!!

Answers

Answer:

No it doesn't

You see when something is in parenthesis () that means it isolated as a whole.  When it says (-6)^2 that means Negative six squared.  When it says -6^2 that means only the 6 will be squared since they are not parenthesized.  So by isolating the two figures both of those numbers together will be squared whereas when they arent isolated only one of them will be squared.

(-6)^2 =  -6 x -6 = 36

-6^2= - x 6 x 6= -36

Answer:

-6^2 is same as (-6)^2

Therefore, - 6^2 is - 6×-6 WHICH IS EQUALS TO 36

(-6)^2 = - 6×-6=36

36=36 is the answer.

Answer:

x^2+y^2 = 49

Step-by-step explanation:

This is a circle.

The generic equation of a circle is

(x-h)^2+ (y-k)^2 = r^2

where (h,k) is the center and r is the radius

The center of the circle is at the origin which is (0,0)

The radius is 7

(x-0)^2+(y-0)^2 = 7^2

x^2+y^2 = 49

Answer:

[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]

Step-by-step explanation:

we are given a circle

we want to figure out the equation of the circle

remember that,

[tex] \rm \displaystyle E _{c} : (x - {h)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]

(h,k) are the centre of the circle

we can clearly see that the centre of the circle is (0,0) and the redious is 7 units

thus substitute:

[tex] \displaystyle (x - {0)}^{2} + (y - 0{)}^{2} = {7}^{2} [/tex]

further simplification is needed:

[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]

and we are done!

X =
Exterior Angle =
3x + 25°
20°
X + 550

Answers

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)}

Please help with Volume

Answers

Given:

Length of the cuboid tank = 4 m

Breadth = 2.5 m

Height = 2.4 m

One third of the tank is filled with water.

1 cubic meter = 1000 liters.

To find:

The quantity of the water in the tank.

Solution:

Volume of a cuboid is:

[tex]V=l\times b\times h[/tex]

Where, l is length, b is breadth and h is the height.

The volume of the tank is :

[tex]V=4\times 2.5\times 2.4[/tex]

[tex]V=24[/tex]

Volume of tank is 24 cubic meter.

One third of the tank is filled with water. So, the volume of the water is

[tex]\dfrac{24}{3}=8[/tex]

The volume of water is 8 cubic meters.

We have,

1 cubic meter = 1000 liters.

8 cubic meter = 8000 liters.

Therefore, the quantity of the water in the tank is 8000 liters.

If there are 258 kids total in school, then let’s take it as 100%
And 74 kids have freckles, so we have to find the % of those kids with freckles.
258–100%

Let’s find 1% of the kids.
258/100=2.58

Now let’s find the % of 74 kids.

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

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.
