Answer:

25%

Step-by-step explanation:

Given data

original quantity =12

new quantity =15

% increase= new-original/original *100

% increase= 15-12/12 *100

% increase= 3/12 *100

% increase=0.25 *100

% increase=25%

hence the increase is 25%

The graph of y = tan ⁡(x − π / 2) compared to the graph of y = tan ⁡x has:
vodomira [7]

Answer:

Last Option moved \frac{\pi}{2} units right

Step-by-step explanation:

If we have a function f(x) and we want to move it horizontally then we make the transformation:

y = f (x + h)

If h then the graph of f(x) moves horizontally h units to the right

If h> 0 then the graph of f(x) moves horizontally h units to the left.

In this case we have the function y = tan (x) and the transformation is performed to obtain y = tan(x- \frac{\pi}{2})

Notice that in this transformation

h

<u><em>Then the graph of y = tan (x) moves horizontally \frac{\pi}{2} to the right</em></u>

I hope i am right

Step-by-step explanation:

Using \: angle\: 40 \\Opposite = 25\\Hypotenuse = ?\\Sin \alpha = \frac{opp}{hyp} \\Sin 40 = \frac{25}{x} \\0.6427= \frac{25}{x}\\0.6427x = 25\\x = \frac{25}{0.6427}\\ x = 38.89\\x = 39\\Using \:Pythagoras\: theorem\\Hyp^2 = Opp^2 +Adj ^2\\39^2=25^2+x^2\\1521=625+x^2\\1521-65=x^2\\896=x^2\\x=29.93\\x = 30\\area = 1/2 \times b \times c \times sin(A).\\b =25\\c =39\\a =30\\A = \frac{1}{2} \times 25  \times 39 \times Sin 30\\A = 487.5\times 1/2\\A =243.75yd^2
