The Sum means an answer to an adition problem

Build a table of values choosing values for  

x

that you think are appropriate. It should look something like this:

You then put small crosses or dots on the graph paper that match the values for y and  

sin  ( x − 45 )

As best as you can draw a smooth free hand curve that connects the points/crosses.

Answer:

tan x = -3 (Answer A)

Step-by-step explanation:

We want to find the tangent of this angle "theta," and recall the trig identity

(sin x)^2 + (cos x)^2 = 1.

               3√10

If sin x = -----------

                   10

                             90

then (sin x)^2 = ----------- = 9/10

                             100

and (cos x)^2 = 1 - 9/10 = 1/10

                      sin x       3√10/10

Then tan x = ---------- = -------------- = -3 (Answer A)

                       cos x      1√10/10

The tangent function is negative in Quadrant II.  In Quadrant I tan x = +3

Answer:

A

Step-by-step explanation:

Using the trig identity

sin²x + cos²x = 1 , then cos x = ± [tex]\sqrt{1-(\frac{3\sqrt{10} }{10})^2 }[/tex]

Given

sinθ = [tex]\frac{3\sqrt{10} }{10}[/tex] , then

cosθ = ± [tex]\sqrt{1-(\frac{3\sqrt{10} }{10})^2 }[/tex]

        = ± [tex]\sqrt{1-\frac{9}{10} }[/tex]

        = ± [tex]\sqrt{\frac{1}{10} }[/tex]

Since θ is in second quadrant where cosθ < 0 , then

cosθ = - [tex]\frac{1}{\sqrt{10} }[/tex]

Then

tanθ = [tex]\frac{sin0}{cos0}[/tex] = [tex]\frac{\frac{3\sqrt{10} }{10} }{\frac{-1}{\sqrt{10} } }[/tex] = - 3 → A

Answer:

397

Step-by-step explanation:

well we know that 6*105= 630 and 2*103 = 206 so we subtract 206 from 630 giving us 397

hope this helps.

Answer:

6×105=630

Step-by-step explanation:

2×103=206 so 6×105 is greater with 424 yimes2×103.

Answer: 1¼ pounds

Step-by-step explanation:

Since 20 pounds of beans are distributed equally into 16 bags to give out at the food bank, the amount of pounds of beans that are in each bag will be gotten by dividing 20 by 16 which will be:

= 20 pounds / 16

= 1¼ pounds

Therefore, there are 1¼ pounds of beans in each bag.

Answer:

6.4

Step-by-step explanation:

As we can see it is a right angled triangle so

perpendicular (p)= 5

base (b) = 4

hypotenuse (h) = c = ?

we know

by using Pythagoras theorem,

h² = p² + b²

or h = √(p² + b²)

c = √( 5² + 4 ² )

c = √41

c = 6.4

Answer: 135 pi

Step-by-step explanation: I took the test

It is a three-dimensional shape with two parallel circular bases and a curve surface.

The volume of water needed to fill the pool is 180π square feet.

It is a three-dimensional shape with two parallel circular bases and a curve surface.

Volume = π r² h

r = radius of the cylinder

h = height of the cylinder

We have,

Diameter of the cylinder = 12 ft

Radius = diameter/2 = 12/2 = 6 ft

Height of the cylinder = 5 ft

The volume of the cylinder:

=  πr²h

=  π x 6² x 5

= π x 36 x 5

= 180π square feet

Thus,

The volume of water needed to fill the pool is 180π square feet.
