Answer:

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin

Step-by-step explanation:

Given

Cost of coat in London = £60

Cost of coat in Dublin = €105.60

In order to find where the coat is cheaper, the price should be in same unit

It is also given that

£1 = €1.65

so,

Price of coat in Euro will be:

P = 60 * 1.65 = 99

So the price of coat in London is 99 Euros

Comparing both the prices we see that

Price in London < Price in Dublin

99 < 105.60

The difference in price is:

=105.60-99= 6.6\ Euros

Hence,

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin

Simply (tan^2 x - sec^2 x)(sin^2 x + cos^2 x)
kati45 [8]

we can use pythagorean identieis

remember that sin^2(x)+cos^2(x)=1

also remember that tan(x)=\frac{sin(x)}{cos{x}} and sec(x)=\frac{1}{cos(x)}

so if we take sin^2(x)+cos^2(x)=1 and divide both sides by cos^2(x) we get

\frac{sin^2(x)}{cos^2(x)}+\frac{cos^2(x)}{cos^2(x)}=\frac{1}{cos^2(x)}

(\frac{sin(x)}{cos(x)})^2+1=(\frac{1}{cos(x)})^2

tan^2(x)+1=sec^2(x)

subtracting 1+sec^2(x) from both sides

tan^2(x)-sec^2(x)=-1

now subsitute into original problem


\frac{tan^2(x)-sec^2(x)}{sin^2(x)+cos^2(x)}=

\frac{-1}{1}=

-1

the answer is -1

For f(x) = 5x + 1
drek231 [11]

Answer:

A. f(7) = 5(7) + 1\\\\f(7) = 36

B. f^{-1}(x) = \frac{x - 1}{5}

C. f^{-1}(7) =\frac{6}{5}

D. f(\frac{6}{5}) = 7

Step-by-step explanation:

A. To solve the first part of the problem we must replace x = 7 in the function f(x) = 5x + 1

So:

f(7) = 5(7) + 1\\\\f(7) = 36

B. In part B we must find the inverse function of f(x) = 5x + 1

To find the inverse function do y = f(x)

y = 5x +1

Now clear the variable x.

\frac{y - 1}{5} = x

Replace x with y.

y = \frac{x - 1}{5}

Finally

f^{-1}(x) = \frac{x - 1}{5}

C. Now we take the inverse function found above and replace x = 7

f^{-1}(7) = \frac{7 - 1}{5}\\\\f(7) = \frac{6}{5}

D. Now we substitute x = f(f^{-1}(7)) in the original function.

x = f( f^{-1}(7))\\\\f^{-1}(7) = \frac{6}{5}\\\\ x= f(\frac{6}{5} )\\\\f(\frac{6}{5}) = 5(\frac{6}{5}) + 1\\\\f(\frac{6}{5}) = 7
