In a 30-60-90 triangle, the rule is:

If opposite of 30° is x,
1) Opposite of 60° is x√3
2) Opposite of 90° is 2x

When we put that into consideration, they gave us the opposite of 90° which is 8. If 8 is 2x, x or opposite of 30° is 4.

For q, we need to multiply s by √3: 4 \times \sqrt{3} = 4 \sqrt{3}

So, q is 4√3.

In a 30-60-90 triangle, the side lengths are in the ratio 1:2:sqrt(3) = short leg: hypotenuse: long leg.

We know the hypotenuse is 8. We can use this to find the other legs.

The short leg s is 8/2 = 4 because the short leg is always half of the hypotenuse.

The long leg q is 4 * sqrt(3), because the long leg is always sqrt(3) times the shorter leg.

So:

s = 4

q = 4 * sqrt(3)

What is 48 square feet in square meters
Marina86 [1]

Answer: 4.45935

Step-by-step explanation: 1 Square foot (sqft) is equal to 0.09290304 square meter (sqm). For example, to convert 100 square feet to square meters, multiply 100 by 0.09290304, that makes 9.290304 sqm is 100 sqft. Hope this helps.

Which statement best describes how to determine whether f(x) = 9- 4x4 is an odd function?
vitfil [10]

Answer:

Option C.

Step-by-step explanation:

Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.

Consider the given function is

f(x)=9-4x^2

If f(-x)=f(x), then f(x) is an even function.

If f(-x)=-f(x), then f(x) is an odd function.

Now, substitute x=-x in the given function.

f(-x)=9-4(-x)^2

f(-x)=9-4(x)^2

f(-x)=f(x)

So, the given function not an odd function. It means it is an even function.

To check whether the given function is odd, we have to determine whether 9-4(-x)^2 is equivalent to -(9-4(x)^2).

Therefore, the correct option is C.

What is the volume of this rectangular
Basile [38]
<h3>Given:</h3>
  • l= 5 m
  • b= 4 m
  • h= 3 m
<h3>Note that:</h3>
  • l= length
  • b= breadth
  • h= height
<h3>To find:</h3>

The volume of the given rectangular pyramid.

<h3>Solution:</h3>

\large\boxed{Formula:V=\frac{1}{3}lbh}

First, multiply the length (5), breadth (4) and height (3).

5×4×3

= 60 \: cm

Now, divide 60 by 3.

\frac{60}{3}

\large\boxed{V= 20 \: {m}^{3}}

<u>Therefore, the volume of the given rectangular pyramid is 20 cubic meters.</u>

What is the area of a circle with a radius of 35 inches<br> in2<br> (Use 3.14 for Pi.)
Amanda [17]

Answer: area= 3846.5 inch^2

Step-by-step explanation:

Area of circle = πr^2

Where r is the radius and pi is 3.14

So, we get..

3.14 x (35)^2

= 3.14 x 35 x 35

= 3.14 x 1225

= 3846.5 inch^ 2
