Answer:

$f(-3x) = 6x + 5$

Step-by-step explanation:

<u>Step 1: Substitute -3x for x</u>

<u /> $f(x) = -2x + 5$

$f(-3x) = -2(-3x) + 5\\$

$f(-3x) = 6x + 5$

Find SP when CP=Rs.400 and proft%=4%

kvasek [131]

Answer:

$\boxed{Selling\ Price = Rs.\ 424}$

Step-by-step explanation:

Cost Price = Rs. 400

Profit = 4 % of Cost Price

=> $\frac{4}{100} * 600$

=> 4 * 6

=> Profit = Rs. 24

Now, Selling Price = Cost Price + Profit

Selling Price = 400+24

Selling Price = Rs. 424

The hypotenuse of a 45 45 90 triangle measures 24 inches. what is the length of one leg of the triangle?

frosja888 [35]

Answer:

$12\sqrt{2}\ in$

Step-by-step explanation:

we know that

A $45\°-45\°-90\°$ right triangle has two equal legs

Let

x-----> the length side of the leg of the triangle

y------> the length side of the hypotenuse

$sin(45\°)=cos(45\°)=\frac{\sqrt{2}}{2}$

$cos(45\°)=\frac{x}{y}$

$\frac{x}{y}=\frac{\sqrt{2}}{2}$

in this problem we have

$y=24\ in$

substitute the value of y and solve for x

$\frac{x}{24}=\frac{\sqrt{2}}{2}$

$x=24\frac{\sqrt{2}}{2}$

$x=12\sqrt{2}\ in$
