D

add 49 to both sides to get x by itself
x^2 - 49 = 0
+49 +49

square root both sides to get rid of the square
√x^2 = √49
x= ±7

since both -7 and 7 are square roots to 49, it’s D

Let f(x) = 5x + 12. Find f^−1(x).

Ira Lisetskai [31]

Answer:

$\huge\boxed{f^{-1}(x)=\dfrac{1}{5}x-3}$

Step-by-step explanation:

$f(x)=5x+15\to y=5x+15\\\\\text{exchange x to y and vice versa}\\\\x=5y+15\\\\\text{solve for}\ y\\\\5y+15=x\qquad|\text{subtract 15 from both sides}\\\\5y=x-15\qquad|\text{divide both sides by 5}\\\\y=\dfrac{1}{5}x-3$

A 30-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 32 m. Find the length

zepelin [54]

Answer: 11.1 m

Step-by-step explanation:

This can be solved by the Pythagorean theorem where;

c² = a² + b²

c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.

a is the height

c is the length

32² = 30² + b²

b² = 32² - 30²

b² = 1,024 - 900

b² = 124

b = √124

b = 11.1 m

Which of these best describes the hypotenuse-angle theorem?

Amiraneli [1.4K]

The hypotenuse angle theorem basically states that if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.

So I would say D is correct
