The measure of angle b would be 68 degrees.

What are complementary angles?

If two angles are given and the sum of the angles of two angles is 90 degrees then the angles are called as complementary angles.

Complementary angles are two angles whose sum is 90 degrees.

Given that angle a measures 22 degrees and it is complementary to angle b, we can use the following equation to find the measure of angle b:

a + b = 90

Substituting the given value of angle a, we get:

22 + b = 90

Subtracting 22 from both sides, we get:

b = 90 - 22

Therefore, the measure of angle b is:

b = 68 degrees.

Hence, the measure of angle b would be 68 degrees.

To find the inverse of a function, just replace X for Y and vice versa

Y + 6 = 3X     replacing X by Y

X + 6 = 3Y      isolating y

(X + 6)/3 = Y⁻¹

Then the inverse of Y + 6 = 3X will be

Jeane read 1,413 pages of books.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Answer:

x = 6, y = - 3

Step-by-step explanation:

Given the product of a complex number and its conjugate, that is

(x + yi)(x - yi) → where x and y are real

= x² + y² ← a real number

Given

(6 + 3i), then we require the conjugate 6 - 3i , that is

(6 + 3i)(6 - 3i)

= 6² + 3² = 36 + 9 = 45 ← a real number

Thus

x = 6 and y = - 3 are the required values

Step-by-step explanation:

Answer:

(f · g)(t - 1) = 4t² - 2t - 13

Step-by-step explanation:

First, find (f · g)(n).  You can do this by multiplying f(n) by g(n).

f(n) = 2n - 2

g(n) = 2n + 5

(f · g)(n) = (2n - 2)(2n + 5)

(f · g)(n) = 4n² + 6n - 10

Now, plug (t - 1) into (f · g)(n) and simplify.

(f · g)(n) = 4n² + 6n - 10

(f · g)(t - 1) = 4(t - 1)² + 6(t - 1) - 10

(f · g)(t - 1) = 4(t² - 2t + 1) + 6(t - 1) - 10

(f · g)(t - 1) = 4t² - 8t + 4 + 6t - 1 - 10

(f · g)(t - 1) = 4t² - 8t + 4 + 6t - 1 - 10

(f · g)(t - 1) = 4t² - 2t + 4 - 1 - 10

(f · g)(t - 1) = 4t² - 2t - 13
