Simplify the Expression:

sqrt 18/ sqrt 49

Answer:

63

Step-by-step explanation:

C=diameterxpi

or C=radius x 2 x pi

the radius is half of diameter so simplify to C=diamerter x pi

C=20x3.14

C=62.8

Answer:

the elevation of the entrance is -21

Step-by-step explanation:

The computation of the elevation of the entrance is shown below;

-15 = -1 + 2 ÷ 3e

e = -21

Hence, the elevation of the entrance is -21

We simply applied the above equation so that we can determine the elevation of the entrance

Answer:

15.6 inches

Step-by-step explanation:

Here we want to find the length of the missing side

Mathematically, we can use Pythagoras’ theorem

The theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides

Let the missing side be x

18 is the side that faces right angle and this is the hypotenuse

Thus, we have ;

x^2 + 9^2 = 18^2

x^2 = 324 - 81

x^2 = 243

x = √(243)

x = 15.6 in

Answer:

The domain of a function is the complete set of possible values of the independent variable. In plain English, the definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

Answer:

41.5

Step-by-step explanation:

you use the trigonometric equations. in this case, we will use SOH:

sin 49=opposite/adjacent

sin 49=x/55

55 sin 49=x

41.50=x

Therefore, x is equals to 41.50. And it is already to it's nearest hundredth.

The value of x is  41.25.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

We use the sin function.

Sin 49 = DE/DF

Sin 49 = x / 55

0.75 = x / 55

x = 0.75 x 55

x = 41.25

Thus,

The value of x is  41.25.

[tex]\frac{\sqrt{21} }{5}[/tex]

Step-by-step explanation:

Given

cosθ = - [tex]\frac{2}{5}[/tex]

Using the identity

sin²θ + cos²θ = 1 , then

sinθ = ± [tex]\sqrt{1-cos^20}[/tex]

       = ± [tex]\sqrt{1-(-\frac{2}{5})^2 }[/tex]

      = ± [tex]\sqrt{1-\frac{4}{25} }[/tex]

      = ± [tex]\sqrt{\frac{21}{25} }[/tex]

     = ± [tex]\frac{\sqrt{21} }{5}[/tex]

Since θ is in second quadrant the sinθ > 0 , thus

sinθ = [tex]\frac{\sqrt{21} }{5}[/tex]

The value of x assuming e that segments that appear to be tangent are tangent is 8

The triangle inside the circle is right angles since the side length "x" is tangential to the circle.

To determine the value of "x", we will use the Pythagorean theorem as shown:

17^2 = x^2 + 15^2

289 = x^2 - 225
x^2 = 289 - 225
x^2 = 64

x = 8

Hence the value of x assuming e that segments that appear to be tangent are tangent is 8

Step-by-step explanation:

Given

Consumer charges = 2530.16cents

Consumer charges in dollars = $25.3016

Interest rate per day = 0.042%

Interest gotten per day = 0.042×25.3016

Interest per day = $1.06266

Interest in 30 days = ,30×1.06266
