-1 ___ 3 ___ 11 ___ 23 ___ 39 ___ ( )

The first blank is . . . . . " + 4 = " .

The second blank is . . " + 8 = " .

The third blank is . . . . " + 12 = " .

The fourth blank is . . . " + 16 = " .

Enter the amplitude of the function f(x) . f(x)=3/4cos(3x)+4

Alisiya [41]

Answer:

The amplitude is $\frac{3}{4}$

Step-by-step explanation:

Let f(x) be a sinusoid function that has the following format:

$f(x) = bsin(wx + s) + h$

Then b is the amplitude of the function

h is the vertical displacement of the wave

s is the phase angle

$\frac{2\pi}{w}$ is the period.

In this problem $f (x) = \frac{3}{4}cos(3x) +4$

Then $\frac{3}{4} = b$

Therefore the amplitude of the function is $\frac{3}{4}$

The amplitude is a measure of the vertical size of the sinx wave

Four different sets of objects contain 2,5,6, and 7 objects, respectively. How many unique combinations can be formed by picking

Ilia_Sergeevich [38]

There are 2 choices for the first set, and 5 choices for the second set. Each of the 2 choices from the first set can be combined with each of the 5 choices from the second set. Therefore there are 2 times 5 combinations from the first and second sets. Continuing this reasoning, the total number of unique combinations of one object from each set is:
$2\times5\times\times6\times7=420\ combinations$

Use the substitution method to solve the given system of equations. Write your answer as an ordered pair, (x, y).

Gnoma [55]

Answer:

(-3, -2)

Step-by-step explanation:

Look at the second equation, we can easily rearrange it to make x the subject.

x - 4y = 5

x = 4y + 5

Now lets put that into the second equation

2x - 2y = -2

2(4y + 5) - 2y = -2

6y + 10 = -2

6y = -12

y = -2

Now lets find x!

x = 4y + 5

x = 4(-2) + 5

x = -3

Now lets format the answer like the question says (ordered pair)

(-3, -2)

Recap: We used substitution and made an equation to work out one of the variables first, then found the second variable using the first.
