Please help im being timed <br><br> Inverse of f(x)=15x+4
rusak2 [61]

Answer:

f^{-1}(x) =

Step-by-step explanation:

let y = f(x), then rearrange making x the subject

y = \frac{1}{5}x + 4 ( subtract 4 from both sides )

y - 4 = \frac{1}{5}x ( multiply both sides by 5 to clear the fraction )

5y - 20 = x

Change y back into terms of x with x = f^{-1} (x) , then

f^{-1} (x) = 5x - 20

Two congruent 30-60-90 triangles are placed,as shown,so that they overlap partly and their hypotenuses coincide. If the hypotenu
Ede4ka [16]

Answer: The area common to both triangle is 31.77 sq. cm.

Step-by-step explanation:

Since we have given that

30-60-90 triangles are placed.

So, the ratio of sides would be

1:\sqrt{3}:2

Since Hypotenuse = 12 cm

So, it becomes,

2x=12\\\\x=\dfrac{12}{2}=6

So, Base would be

x=6\ cm

and Perpendicular would be

\sqrt{3}x=6\sqrt{3}

So, Area common to the both triangles would be

\dfrac{1}{2}\times base\times height\\\\=\dfrac{1}{2}\times 6\times 6\sqrt{3}\\\\=18\sqrt{3}\\\\=31.177

Hence, the area common to both triangle is 31.77 sq. cm.
