Answer:

The answer is 45ft : 36ft

Step-by-step explanation:

Divide 81 ft in the ratio 5 : 4

total ratio = 5 + 4

= 9

5/9 × 81

405/9 = 45 ft

4/9 × 81

324/9 = 36 ft

45ft : 36ft

Hope this helps!

Hi!

We can see here that this is a composition question.

And since the composition of g of f of x is x, we can conclude that g(x) is the inverse of f(x) (if you're confused, search up the definition of an inverse function).

To find an inverse function, we can take the f(x) function and change the positions of the x and y variables.

f(x)=\frac{e^7^x+\sqrt{3}}{2}

y=\frac{e^7^x+\sqrt{3}}{2}

x=\frac{e^7^y+\sqrt{3}}{2}

2x=e^7^y+\sqrt{3}

e^7^y=2x-\sqrt{3}

7y=ln(2x-\sqrt{3})

y=\frac{ln(2x-\sqrt{3})}{7}

Which is answer choice A, to check your work, you can solve the composition of g(f(x)), which will get you x.

g(f(x))

g(\frac{e^7^x+\sqrt{3}}{2})

\frac{ln(2(\frac{e^7^x+\sqrt{3}}{2})-\sqrt{3}}{7}

2s cancel.

\frac{ln(e^7^x+\sqrt{3})-\sqrt{3}}{7}

The natural log and e cancel.

\frac{7x+\sqrt{3}-\sqrt{3}}{7}

\sqrt{3}s cancel.

\frac{7x}{7}

7s cancel.

x

Hope this helps!

George wrote an integer. The opposite of George's integer is - 53. Which of these statements about George's integer must be true
Readme [11.4K]

Answer:

D I and IV

Step-by-step explanation:

The opposite of an integer "x" is "-x".

I. The integer is 53.  →  Since the opposite of George's integer is -53, the integer is -(-53) = 53

II. The integer has an absolute value of - 53.  →  The absolute value of 53 is 53.

III. The integer is - 53.  →  It was 53, found in I.

IV. The integer has an absolute value of 53.  →  It has an absolute value of 53, found in II.
