What is the measure of x to the nearest degree?<br> 8
faust18 [17]

We know that :

\sf{\bigstar \ \ Cos\theta = \dfrac{Adjacent \ Side}{Hypotenuse}}

From the figure, We can notice that :

Ф   Adjacent side length = 8

Ф  Hypotenuse length = 11

\sf{\implies Cosx^{\circ} = \dfrac{8}{11}}

\sf{\implies x^{\circ} = Cos^{-1}\bigg(\dfrac{8}{11}\bigg)}

\sf{\implies x^{\circ} = 43.34}

Convert the decimal 0.8034 to a fraction and classify it as either rational or irrational.
Llana [10]

Answer:

Fractional form of 0.8034  =\frac{4017}{5000}

Since 4017 and 5000 are whole numbers this fraction is rational.

Step-by-step explanation:

We have 0.8034=\frac{8034}{10000} =\frac{4017}{5000}

Fractional form of 0.8034  =\frac{4017}{5000}

Since 4017 and 5000 are whole numbers this fraction is rational.

Answer, please. I need help.
Ghella [55]

Answer:

-8x^12

Step-by-step explanation:

When you have an exponent outside of parenthesis, it is raising everything in the parenthesis to that exponent (in this case, the third). The first step to solve this is to multiply the exponents in the parenthesis by 3. This is called the power of a power rule.

-2 is being raised to the first power. 1x3 = 3, and x is being raised to the fourth power. 4x3 = 12, so you now have:

-2^3x^12

You can simplify -2^3: -2 x -2 x -2 = -8

This leaves you with -8x^12

You can check this by putting -8x^12 and (-2x^4)^3 into a graphing calculator. You know that you simplified correctly if they show the same graphs.

a 32m tall building cast a shadow. the distance from the top of the building to the tip of the shadow is 35m. find the length of
icang [17]

The length of the shadow is 14.2 m

Right angle triangle:

Right angle triangle has one of its sides as 90 degrees.

The height of the building is the opposite side of the triangle.

The distance from the top of the building to the tip of the shadow is 35 m is the hypotenuse side.

The length of the shadow is the adjacent side of the triangle.

Therefore,

c² = a² + b²

b² = 35² - 32²

b² = 1225 - 1024

b² = 201

b = √201

b = 14.17

b = 14.2 m

Hence the length of the shadow is 14.2 m.
