The given equation is a geometric sequence.
It has a common ratio. You can get it by dividing the number in the sequence by the number before it.

Just like r= 16/4= 4

Please help me!!!! precalc question
dangina [55]

Step-by-step explanation:

1. Ampltiude is 1

The period is

\frac{2\pi}{3}

is the period

The phase shift is 0

2. The Ampltiude is 2

The period is 2 pi

The phase shift is 1

3. The amplitude is 3

The period is 2 pi/3

The phase shift is -2

4.The amplitude is 2/3

The period is -10pi

The phase shift is 0

5. The Ampltiude is 1

The period is -2 pi

The phase shift is pi

6. The amplitude is 1/4

The period is -4pi

The phase shift is negative 2pi/3

7. The Ampltiude is 3

The period is 4

The phase shift is 8

Find an obtuse angle whose sine is<br> a) 0.25<br> b) 0.75<br> c) 0.875<br> d) 0.3465
swat32

Answer:

a) 165.52 degrees.

b)  131.41 degrees.

c)  118.96 degrees.

d)  159.73 degrees.

Step-by-step explanation:

The sine of an obtuse angle is positive as it is in the second quadrant.

a) Using a calculate the angle whose sine ( arcsin) is 0.25  = 14.478 degrees

so the obtuse angle  = 180 - 14.478 = 165.52 degrees to nearest hundredth

b) c) and d) are calculated in the same way.

X<br> (2x - 7)^3= (2x)^3- 7^3<br> = 8x3 - 343
emmainna [20.7K]

Answer:

(2x - 7)³ ≠ (2x)³- 7³

Step-by-step explanation:

(2x - 7)³= (2x)³- 7³

Use pascal's triangle to expand left side. Simplify all else.

(2x)³ + 3(2x)²(-7)¹ + 3(2x)¹(-7)² + (-7)³ = 8x³- 343

8x³ + 3(4x²)(-7) + 3(2x)(49) + (-7)³ = 8x³- 343

8x³ - 84x² + 294x - 343 = 8x³- 343

Answer:

Step-by-step explanation:

So, what is a quotient?  Well, a quotient is like the sum, difference and product.  When you add two numbers you get their sum, difference is for subtraction and product is for multiplication.  So quotient is for division, or in other words the answer to a division problem.

Now, it's asking for the quotient of 91 and x, it isn't specifying which is being divided by which but it sound like it wants the first divided by the second.  So that's 91 divided by x
