Answer:

b. 36

Step-by-step explanation:

You have to use Pythagorean theorem. A squared + b squared = c squared.

a=12 12^2 (12 squared)= 144

b=9 9^2 (9 squared)= 81

144+81=225

Then you find the square root of 225 which is 15. Since you have the length for side c.

12+9+15=36

Answer:

Step-by-step explanation

You would first have to find the hypotenuse to do that you would follow the formula c = √a²+b², giving you 15.

Next you would add all the sides P = a+b+c, giving you 36.

The perimeter of this triangle would be 36.

Prove that f(x)=x+3/2 and g(x)=2x-3are inverse

goldfiish [28.3K]

Answer:

Proofs

Step-by-step explanation:

$f(x) = x + \frac{3}{2}$

$y = x + \frac{3}{2}$

$x = y + \frac{3}{2}$

$x - \frac{3}{2} = y$

${f}^{ - 1} (x) = x - \frac{3}{2}$

They are not inverse because f^-1(x) = x - 3/2 is not the inverse to g(x) = 2x - 3.

Answer:

x = y = 12

Step-by-step explanation:

A right triangle with a 45° angle is an isosceles right triangle. That means the legs are both the same length. The side ratios of such a triangle are ...

1 : 1 : √2

Multiplying these ratios by 12 gives ...

12 : 12 : 12√2 = x : y : 12√2

The side lengths x and y are both 12 units.

What is the effect on the graph of f(x) = 1 when it is transformed to

ivann1987 [24]

Answer: C) Shifted 16 units down

The minus 16 at the end is directly the reason why. Think of y = 1/x, and subtracting 16 from both sides to get y-16 = (1/x) - 16. The y-16 will shift every point down 16 units. For instance, the point (1, 1) moves to (1, -15).
