7 0

Answer:

18,72

Step-by-step explanation:

Complementary angles add to 90 degrees

Multiply the ratio by x

1x+4x = 90

Combine like terms

5x = 90

divide by 5

5x/5 = 90/5

x =18

The first angle is 18 degrees

4*18 =72

The second angle is 72 degrees

Let f (x) = 1/x<br> and g(x) = x² – 3x. What<br> two numbers are not in the domain of fºg?
iren [92.7K]

For this case we have the following equations:

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

We must find (f_ {o} g) (x):

By definition of composition of functions we have to:

(f_ {o} g) (x) = f (g (x))

So:

(f_ {o} g) (x) = \frac {1} {x ^ 2-3x}

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.

x ^ 2-3x = 0\\x (x-3) = 0

So, the roots are:

x_ {1} = 0\\x_ {2} = 3

The domain is given by all real numbers except 0 and 3.

Answer:

x other than 0 and 3

How could you use coordinate geometry to prove that segment BC is congruent to segment AD?
liberstina [14]

Answer:

  Prove the lengths are the same

Step-by-step explanation:

When we say segments are congruent, we mean their lengths are the same.

__

Let's see if they are congruent.

  AD = √((3-(-3))² +(2-2)²) = 6

  BC = √((6-0)² +(6-6)²) = 6

AD ≅ BC . . . . their lengths are the same
