What is the period of the sinusoid given by y=-4 sin(2 pi/3 x)?

Answers

The period of a sinusoidal curve can be determined through the formula : P = 2π / B where B is equal to 2π / 3. In this case, P = 2π / 2π / 3 equal to 3. The amplitude or the height of the curve is equal to -4. The curve passes through the origin, (0,0). Answer is 3

Write 5,806 in scientific notation.

Answers

Answer:

Step-by-step explanation:

In scientific notation, we represent numbers as a product of a decimal number between 1 and 10, multiplied by a power of 10. This allows us to express very large or very small numbers in a compact and standardized format.

To express 5,806 in scientific notation, we need to move the decimal point to the left so that the number becomes a value between 1 and 10. The number of places we move the decimal point determines the power of 10.

Here's how we can do it step by step:

1. Start with the given number, 5,806.

2. Move the decimal point to the left until the number becomes a value between 1 and 10. In this case, we need to move the decimal point three places to the left.

- 5,806.0 -> 580.60 -> 58.06 -> 5.806

3. Count the number of places you moved the decimal point. In this case, we moved it three places to the left.

4. Write the number as a product of the decimal number and 10 raised to the power of the number of places you moved the decimal point.

- 5.806 x 10^3

Therefore, 5,806 in scientific notation is 5.806 x 10^3.

Remember, scientific notation is a useful way to represent large or small numbers and make them easier to work with in calculations and comparisons.

Which products result in a perfect square trinomial? Check all that apply.A=(–x + 9)(–x – 9)
B=(xy + x)(xy + x)
C=(2x – 3)(–3 + 2x)
D=(16 – x2)(x2 – 16)
E=(4y2 + 25)(25 + 4y2)

Answers

The correct answers are:

B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)

Explanation:

In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same.  For (xy+x)(xy+x), are multiplying two identical binomials.

For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order.  The same is true of (4y² + 25)(25 + 4y²).

Answer:

A and E and C

Step-by-step explanation:

A perfect square trinomial can be written as the square of a binomial.

Joshua does not want to spend more than $22 on a long-sleeve shirt. Which description of shirt prices would keep joshua within his spending limit, not including tax? Select all that apply a- 15% off %25 b- 30% off 32% c-19.65 plus 2.35 shipping fee d- 20.45 plus a $1.60 shipping fee

Answers

Answer:

the answer is C

Step-by-step explanation:

19.65 + 2.35 is exactly 22, not including tax

Answer:

A and C

Step-by-step explanation:

A. 15% off $25

15% = 0.15

0.15 x 25 = 3.75

25 - 3.75 = 21.25

22 or under? Yes

B. 30% off $32

30% = 0.30

0.30 x 32 = 9.60

32 - 9.60 = 22.40

22 or under? No

C. $19.65 plus a 2.35 shipping fee

19.65 + 2.35 = 22

22 or under? Yes

D. $20.45 plus a $1.60 shipping fee

20.45 + 1.60 = 22.05

22 or under? No

Even though this is late, the other answer did not mention A being the answer as well so I hope this helped!

Fiona is going to jog once around the block she lives on. The block is rectangular, and it is 180 yards long and 200 feet wide. How far will Fiona jog (in feet)?

Answers

Perimeter is the sum of the length of the sides used to make the given figure. The distance that Fiona will jog is 760 yards.

What is the perimeter?

Perimeter is the sum of the length of the sides used to make the given figure.

Given that the block is rectangular, and it is 180 yards long and 200 feet wide. Now, given that Fiona is going to Jog once around the block, therefore, the distance that Fiona will cover is the perimeter of the block.

Thus, the perimeter of the block is,

The perimeter of the block = 2(Length + Width)

                                              = 2(180 yards + 200 yards)

                                              = 2(180 yards + 200 yards)

                                              = 2(380 yards)

                                              = 760 yards

Hence, the distance that Fiona will jog is 760 yards.

all you have to do for this question is times 180 by two since there is two sides. after you do that you would get 360 yards. next step would be calculate how many feet are in 360 yards. there are 3 feet in one yard, so you would multiply 360 by 3 to get 1,080 feet. now you do the same steps but with the other side which is 200. times by 2 because there is 2 sides to get 400 yards. now calculate the feet 400*3=1,200. finally you would add the two numbers to see how far fiona jogged which would be 1,080 plus 1,200 to get 2,280 feet.
