construct a right-angled triangle ABC where angle A =90 degree , BC= 4.5cm and AC= 7cm. please ans fast........ Very urgent. Pls

Katena32 [7]

Answer and Step-by-step explanation: The described right triangle is in the attachment.

As it is shown, AC is the hypotenuse and BC and AB are the sides, so use Pytagorean Theorem to find the unknown measure:

AC² = AB² + BC²

$AB^{2} = AC^{2}-BC^{2}$

$AB =\sqrt{AC^{2}-BC^{2}}$

$AB =\sqrt{7^{2}-4.5^{2}}$

$AB =\sqrt{28.75}$

AB = 5.4

Then, right triangle ABC measures:

AB = 5.4cm

BC = 4.5cm

AC = 7cm

If f(x) = 6x + 3, find −1 ().

lianna [129]

Answer:

$f^{-1}(x)=(1/6)x-(1/2)$

Step-by-step explanation:

we have

$f(x)=6x+3$

Find the inverse function $f^{-1}(x)$

step 1

Let

y=f(x)

$y=6x+3$

step 2

Exchanges variables, x for y and y for x

$x=6y+3$

step 3

isolate the variable y

$x=6y+3$

$6y=x-3$

$y=(1/6)x-(1/2)$

step 4

Let

$f^{-1}(x)=y$

$f^{-1}(x)=(1/6)x-(1/2)$
