Answer:

y = 0.5 cosine (4 (x - pi/2)) - 2

Step-by-step explanation:

Taking the general form:

y = A cosine (Bx - Cπ)) + D

In the following case. the constants are:

y = 0.5 cosine (4x - 2π)) - 2

A: 0.5

B: 4

C: 2π

D: -2

The range of this function is:

range = [-|A|+D, |A|+D]

range = [-0.5-2, 0.5-2]

range = [-2.5, -1.5]

Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"

At x = 0, the function value is:

y = 0.5 cosine (4(0) - 2π)) - 2

y = 0.5 - 2 = -1.5

As indicated in "a curve crosses the y-axis at y = negative 1.5"

The period of the function is:

period: 2π/B

period = 2π/4 = π/2 or 2 cycles at π

as described in "It goes through 2 cycles at pi."

Answer:

B) y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2

You can trace a right triangle with these features:

- the 6 feet distance represents the horizontal distance from you to the TV, this is the base of the triangle or the adjacent leg

- the 8 feet distance is the vertical distance from the base of the triangle to the TV, this is the height of the triangle or opposite leg.

- the angle theta that you make with the top of your TV is

 tan (theta) = opposite leg / adjacent leg = 8/6 =4/3

=> theta = arctan (4/3) = 53.13 degrees.

Answer: 53.103 degrees

Answer:

(C)The relationship is multiplicative  because the number of gallons can be

found by multiplying the number of  minutes by 8.

Step-by-step explanation:

Given the table below which shows the relationship between the number of minutes that a hose  has been on and the number of gallons of water that have been added to a  plastic pool.

[tex]\left|\begin{array}{c|c}$Minutes Hose On&$Gallons of Water in Pool\\-------&-------\\0&0\\5&40\\10&80\\15&120\\20&160\end{array}\right|[/tex]

We can see that if we multiply the first column by 8, we will obtain the second column. Therefore the relationship is multiplicative because the number of gallons can be  found by multiplying the number of  minutes by 8.

The correct option is C.

Answer: For this all you have to do is find the distance between the two points. Since you have the centre and a point the lies on the circle, the radius is simply the distance from the centre to the point.

Answer:

Step-by-step explanation: As shown in the attached figure, regular hexagon FGHIJK and square ABCD shares common centre on the co-ordinate plane and AB || FG.

We are to find the line across which the combined figure will reflect onto itself.

In the attached figure, we see two lines which are yellow in colour. We can easily detect that the figure will be reflected onto itself if these two lines acts as a mirror separately.

Hence these yellow lines are the required lines."

Answer:

-13,1

Step-by-step explanation:

f(x)= (x+6)^2-49

When we find the zero's  we set f(x) =0

0= (x+6)^2-49

Add 49 to each side

49= (x+6)^2-49+49

49= (x+6)^2

Take the square root of each side

±sqrt(49) = sqrt((x+6)^2)

±7 = (x+6)

Subtract 6 from each side

±7-6 = (x+6-6)

±7-6 = x

7-6 =x               -7-6 =x

1=x                 -13=x

Answer: 140 m3

Step-by-step explanation:

Multiply the area of the trapezoid face by the length .

Since the area is 20, you multiply it by 7 to get 140

Answer:

140 m^3

Step-by-step explanation:

This is a prism with a trapezoid base.

The volume if a prism is

V = (area of base) * height

The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.

area of trapezoid = (b1 + b2)h/2

In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.

V = (area of base) * (height of trapezoid)

V = (8 m + 2 m)(4 m)/2 * 7 m

V = 20 m^2 * 7 m^2

V = 140 m^3

Answer:

if it was out of all of the data it would be 76 / 300

Answer:

To find the radius You have to take the circumference of the circle and divide it by 2 times π (pi)

To find the center you draw a chord across the circle (a line across the circle near the edge so it cuts the circumference in two places- if you didn't know) then you find the mid point of the chord, and add a chord or two to determine where they meet in the center

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Our equation is:

[tex]\frac{2}{3} *(\frac{1}{2} x+12)=\frac{1}{2} *(\frac{1}{3} x+14)-3[/tex]

Let's first distribute the left side. When distributing, we essentially find the sum of the product of the outside term with each of the inside terms. Here, the outside term is 2/3 and the inside terms are 1/2x and 12. So:

[tex]\frac{2}{3} *(\frac{1}{2} x+12)=\frac{2}{3} *\frac{1}{2} x+\frac{2}{3} *12=\frac{1}{3} x+8[/tex]

Now distribute the right side. Here, the outside term is 1/2 and the inside terms are 1/3x and 14, so:

[tex]\frac{1}{2} *(\frac{1}{3} x+14)-3[/tex]

[tex]\frac{1}{2} *(\frac{1}{3} x+14)-3=\frac{1}{2} *\frac{1}{3} x+\frac{1}{2} *14-3=\frac{1}{6} x+7-3=\frac{1}{6} x+4[/tex]

We now have:

[tex]\frac{1}{3} x+8=\frac{1}{6} x+4[/tex]

Isolate the variable by bringing 1/6x to the left and bringing 8 to the right:

[tex]\frac{1}{3} x-\frac{1}{6} x=4-8[/tex]

[tex]\frac{2}{6} x-\frac{1}{6} x=-4[/tex]

[tex]\frac{1}{6} x=-4[/tex]

x = -4 * 6 = -24

The answer is A.

Steps to solve:

2/3(1/2x + 12) = 1/2(1/3x + 14) - 3

~Distribute

1/3x + 8 = 1/6x + 7 - 3

~Combine like terms

1/3x + 8 = 1/6x + 4

~Subtract 1/6x to both sides

1/3x + 8 - 1/6x = 1/6x + 4 - 1/6x

~Simplify

1/6x + 8 = 4

~Subtract 8 to both sides

1/6x + 8 - 8 = 4 - 8

~Simplify

1/6x = -4

~Multiply 6 to both sides

1/6x * 6 = -4 * 6

~Simplify

x = -24

Best of Luck!

Answer:

The perimeter of rectangle ABCD = 16 units

Step-by-step explanation:

The vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).

AB is horizontal, so measre the difference between the x coordinates of A and B.

between -2 and 3 are 5 units.

BC is vertical, so measre the difference between the y coordinates of B and C.

between 4 and 1 is 3 units.

The perimeter = 2 * ( AB + BC )

Substitute AB = 5 and CD = 3

2 * ( 5 + 3 )

2 * 8

The perimeter of rectangle ABCD = 16 units

Answer:

16 units

Step-by-step explanation:

finding the lengths of all sides which are 5,5,3, and 3 then adding them will get you 16 units.

Answer:

a(91) = -1705

Step-by-step explanation:

Each successive term is 19 less than the previous term, so the common difference is 19, and the general term is a(n) = a(1) - 19(n - 1).

Thus, the 91st term is    a(91) = 5 - 19(91 - 1), or

                                        a(91) = 5 - 1710, or

                                        a(91) = -1705

The 91st term of the arithmetic sequence is -1705.

An arithmetic progression is a sequence of numbers such that the difference of any two successive members is a constant.

Given that an arithmetic sequence 5, -14, -33, ...

nth term of an AP is, a(n) = a + (n-1)d

Each successive term is 19 less than the previous term, so the common difference is 19, and the general term is a(n) = a(1) - 19(n - 1).

Thus, the 91st term is  

a(91) = 5 - 19(91 - 1)

a(91) = 5 - 1710

a(91) = -1705

Hence, The 91st term of the arithmetic sequence is -1705.
