Answer:

∠A = 120°

∠B = 60°

Step-by-step explanation:

Since, ∠A and ∠B form a linear pair.

Therefore,

∠A + ∠B = 180°.....(1)

It is given that:

∠A = 2∠B..... (2)

From equations (1) & (2)

2∠B + ∠B = 180°

3∠B = 180°

∠B = 180°/3

∠B = 60°

So, ∠A = 2∠B = 2*60°

∠A = 120°

Pavel [41]

Answer:

G=\frac{Fr^2}{m_1m_2}

Step-by-step explanation:

Since our equation is F=\frac{Gm_1m_2}{r^2} and we want to solve for G, first we divide both sides by the product m_1m_2, which gives:

\frac{F}{m_1m_2}=\frac{Gm_1m_2}{m_1m_2r^2}=\frac{G}{r^2}

So we are left with:

\frac{F}{m_1m_2}=\frac{G}{r^2}

Now we multiply both sides by r^2, which gives:

\frac{Fr^2}{m_1m_2}=\frac{Gr^2}{r^2}=G

Which gives us our final formula:

G=\frac{Fr^2}{m_1m_2}

Why do we learn properties of real numbers?<br><br><br> answer quick :D
atroni [7]

Answer:

The properties of the Real Number System will prove useful when working with equations, functions and formulas in Algebra, as they allow for the creation of equivalent expressions which will often aid in solving problems. In addition, they can be used to help explain or justify solutions.

Show f and g are inverse functions. Show analytically and graphically. I don’t know if I’m right but would like to know.
Aleks [24]

Hello!

To prove that f(x) = 2x - 1 and g(x) = x/2 + 1/2, we can use a composite function. Composite functions are basically (f ∘ g)(x). It combines two functions into one. If they are true inverses, then the answer must be equal to x.

(f ∘ g)(x) = 2(x/2 + 1/2) - 1

(f ∘ g)(x) = x + 1 - 1

(f ∘ g)(x) = x

(g ∘ f)(x) = (2x - 1)/2 + 1/2

(g ∘ f)(x) = x - 1/2 + 1/2

(g ∘ f)(x) = x

Since (g ∘ f)(x) and (f ∘ g)(x) are both equal to x, then the functions of f(x) and g(x) are inverses of each other.

Also, in order for two functions to be inverses, these two functions need to be reflected over the line y = x. In the graph shown below, y = x is in red, y = 2x - 1 is blue, and y = x/2 + 1/2 is green. Looking the graph, you can see they are reflected over the line y = x.

Therefore, the function f(x) = 2x - 1 and g(x) = x/2 + 1/2 are true inverses of each other.

Find the zeros of the function. Write the smaller solution first, and the larger solution second. G(x)=4x^2-484
Oduvanchick [21]

Answer:

-11, 11

Step-by-step explanation:

You have to find when the function crosses the x-axis. You could find this using algebra by solving for x in the equation but I prefer to simply graph it using something like desmos and see when it crosses the x-axis. Doing that I can see the answers would be -11 and 11
