Answer:

[tex]y=2\cos(2x+\frac{1}{4})-2[/tex]

or

[tex]y=-2\cos(2x+\frac{1}{4})-2[/tex]

Step-by-step explanation:

[tex]y=a cos(c(x-b))+d[/tex] has:

1) amplitude=|a|

2) phase shift=b

3) period=2pi/c

d) vertical shift=d

--------------------------------------------------

You are given the amplitude is 2. This means a could either be 2 or -2.

You are given phase shift is -1/8. This means b is -1/8.

You are given the period is pi. So we need to solve pi=2pi/c.

pi=2pi/c

Dividing both sides by pi gives:

1=2/c

Multiply both sides by c gives:

c=2

The vertical shift is -2 so d=-2.

The equation could either be:

y=2cos(2(x-(-1/8)))-2

or

y=-2cos(2(x-(-1/8)))-2

Simplifying a little gives:

y=2cos(2x+1/4)-2

y=-2cos(2x+1/4)-2

Answer:

Width = 12 cm

Length = 14 cm

Step-by-step explanation:

Rectangle:

Let the width  = x cm

So, the length = (x+2) cm

Perimeter  = 52 cm

2 *(l+b) = 52

2 *(x+2  + x) =  52

   2 * ( 2x + 2) = 52

           2x + 2  = 52/ 2

           2x + 2  = 26

                 2x = 26- 2

                  2x = 24

                    x = 24/2

                    x = 12

Width = 12 cm

Length = 14 cm

15 < 10

15 is not less than 10.

Answer:

86

Step-by-step explanation:

since the slot is 130 cm thick you divide that by the thickness of the candy bar 130/1.5 and then you get 86.6666666.....which rounds to 86 because the slot is not thick enough for another candy bar. good luck on whatever you needed this for!

In this literal equation, the only thing we will have to do is get t by itself. In order to do that we will perform the opposite relation it has with 7, which is division, on both sides.

The answer will be x divided by 7 equals t, x / 7 = t.

Answer:

12,9,6

Step-by-step explanation:

12=23 3/20. 9=19 4/5. 6=16 5/8.

The infant's weight was gain the greatest during (0 - 3 Months) three-month period.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

The weight gain during (0 - 3 Months) three-month period

⇒ 12 1/2 - 7 1/4 = 25/2 -29/4 = 12.5-7.25 = 5.25 lb

The weight gain during (3 - 6 Months) three-month period

⇒ 16 5/8 - 12 1/2 = 16.625 - 12.5 = 4.125 lb

The weight gain during (6 - 9 Months) three-month period

⇒ 19 4/5 - 16 5/8 = 19.8 - 16.625 = 3.175 lb

The weight gain during (9 - 12 Months) three-month period

⇒ 23 3/20 - 19 4/5 = 23.15 - 19.8 = 3.35 lb

Therefore, the infant's weight was gain the greatest during (0 - 3 Months) three-month period.

Answer:

bottom left is -2x and bottom right is -3

Step-by-step explanation:

if you were to use a timeline you subtract 5 from 3 and that leaves you -2 and add the x from before and for the bottom right 2 - 5 is negative three if you need help its easy to make a timeline

Answer: Wayne is 35, Mark is 34, and Stan is 33.

33+34+35 = 102

Stan is 33 years old, Mark is 34 years old, and Wayne is 35 years old.

Let's solve the problem step by step:

Let's assume Stan's age to be x.

According to the given information, Mark's age is one more than Stan's age, so Mark's age is x + 1.

Similarly, Wayne's age is one more than Mark's age, so Wayne's age is (x + 1) + 1 = x + 2.

Now we know that the sum of their ages is 102, so:

x + (x + 1) + (x + 2) = 102

Combining like terms, we get:

3x + 3 = 102

Simplifying the equation, we get:

3x = 99

Dividing both sides by 3, we get:

x = 33

Now we can substitute the value of x in the previous equations:

Stan's age = 33

Mark's age = 33 + 1 = 34

Wayne's age = 34 + 1 = 35

So, Stan is 33 years old, Mark is 34 years old, and Wayne is 35 years old.

Answer:

9(x+5)=9(5+x)

Step-by-step explanation:

This is tricky because you were probably thrown off by the multiplication step from the parentheses. Since the question wants you to demonstrate your knowledge of the commutative property of addition, you will only worry about inside the parentheses.

So, the commutative property is basically just moving numbers/variables around the addition sign to show that the answer will remain the same either way.

Because of this, we can simply move the (x+5) around to (5+x).

Final answer: 9(x+5)=9(5+x)

Answer:

2x - y = 7

Step-by-step explanation:

Parallel lines have the same slope and the equation will have the same form

That is

2x - y = c ← c will have different values depending on the point it passes through.

Here the line passes through (3, - 1 ) , thus substituting into the left side

2(3) - (- 1) = 6 + 1 = 7 ← value of c, hence

2x - y = 7 ← equation of line

The line's equation is y = 2x - 7.

In geometry, the coplanar straight lines that do not intersect at any point are called parallel lines. The slopes of parallel lines are equal because they are equally inclined with the positive x-axis.

The equation of the given line is

2x-y = 6

i.e. y = 2x-6

We know that If the equation of a line can be expressed as y = mx+c, then the slope of this line is m.

So, the slope of this given line is 2.

We can assume that the equation of the line which is parallel to the given line can be written as

y = 2x + c ...(1)

, where c is a constant.

Since this line passes through the point (3, -1), you have to put x = 3 and y = -1 in (1), to get the value of the constant.

Now, c = y - 2x = (-1) - 2*3 = (-1) - 6 = -7

Putting this value in (1), we get

y = 2x - 7

Therefore the required equation of the line is y = 2x - 7.

Answer:

f(x) is greater.

Step-by-step explanation:

if you replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9

The  function that has a greater value when x = 3 is option A: f(x) is greater.

The function [tex]\(f(x) = 3x + 1\)[/tex] is a linear function with a slope of 3 and a y-intercept of 1. The function[tex]\(g(x)\)[/tex] is not explicitly provided in your question, so we don't have information about its slope or intercept.

To determine which function has a greater value when x = , we need to evaluate both functions at x = 3 and compare their values.

So, when one replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9

Step-by-step explanation:

equivalent sets have the same number of members

Sets A and B are not equivalent, have the same cardinality but no common elements in their intersection.

The sets A and B are not equivalent because they have different members.

The cardinality of set A is 4, and the cardinality of set B is also 4, meaning they have the same number of elements.

The intersection of sets A and B is the empty set, as they have no common elements.
