Answer:
D
Step-by-step explanation:
Note that I will be using a, b, and y instead of their Greek counterparts.
First, we know that sin(c+d) = sin(c)cos(d) + cos(d)sin(a) and sin(c-d) = sin(c)cos(d) - cos(d)sin(a). We can apply these here to get
sin(b+y) = sin(b)cos(y) + cos(b)sin(y)
sin(b-y) = sin(b)cos(y) - cos(b)sin(y)
sin(a+y) = sin(a)cos(y) + cos(a)sin(y)
sin(a-y) = sin(a)cos(y) - cos(a)sin(y)
Plugging these into our equation, we get
(sin(b)cos(y) + cos(b)sin(y) - (sin(b)cos(y) - cos(b)sin(y)))
/
(sin(a)cos(y) + cos(a)sin(y)-(sin(a)cos(y) - cos(a)sin(y)))
=
2cos(b)sin(y) / 2cos(a)sin(y)
= cos(b)sin(y)/cos(a)sin(y)
= cos(b)/cos(a)
Next, we can see that a+b = π, so we can subtract b from both sides to get a = π -b. Plugging that in for a in our equation, we get
cos(b) / cos(π-b)
After that, we know that cos(c-d) = cos(c)cos(d) - sin(c)sin(d). Plugging that in here, we get
cos(π-b) = cos(π)cos(b) - sin(π)sin(b)
= -cos(b) + 0
= -cos(b)
Plugging that back into our equation, we get
cos(b) / -cos(b) = -1

A 10 oz bottle of shampoo cost $2.40 and a 12oz bottle cost $2.64 find the unit rate for each which bottle has the lower unit cost
Answer:
12oz bottle
Step-by-step explanation:
10 oz bottle
Take the price and divide by the ounces
2.40 /10 = .24 per ounce
12oz bottle
2.64 / 12 =.22 per ounce
[tex](4v^{-3} )^3/3v^{-8}[/tex]
Answer:
[tex]=\frac{64}{3v}[/tex]
Step-by-step explanation:
One is given the following equation:
[tex]\frac{(4v^-^3)^3}{3v^-^8}[/tex]
Simplify the numerator, remember to raise every number inside the parenthesis to the exponent outside of the parenthesis. Bear in mind, an exponent raised to another exponent is equal to the exponent times the exponent it is raised to. Then simplify by multiplying the number by itself the number of times that the exponent indicates.
[tex]\frac{(4v^-^3)^3}{3v^-^8}[/tex]
[tex]=\frac{4^3(v^-^3)^3}{3v^-^8}[/tex]
[tex]=\frac{4^3v^-^9}{3v^-^8}[/tex]
[tex]=\frac{64v^-^9}{3v^-^8}[/tex]
Bring the variable (v) in the denominator (value under the fraction bar) to the numerator (value ontop of the fraction bar) by multiplying its exponent by (-1). This can be done simply because all operations in this equation are multiplication or division, remember, an exponent is another form of multiplication.
[tex]=\frac{64v^-^9}{3v^-^8}[/tex]
[tex]=\frac{(64v^-^9)(v^(^-^1^)^(^-^8^))}{3}[/tex]
Simplify, remember, multiplying two numbers with the same base that have an exponent is the same as adding the two exponents,
[tex]=\frac{(64v^-^9)(v^(^-^1^)^(^-^8^))}{3}[/tex]
[tex]=\frac{(64v^-^9)(v^8)}{3}[/tex]
[tex]=\frac{64v^-^9^+^8)}{3}[/tex]
[tex]=\frac{64v^-^1}{3}[/tex]
Now bring the variable to the denominator so that there are no negative exponents. Use a similar technique that was used to bring variables with exponents to the numerator.
[tex]=\frac{64v^-^1}{3}[/tex]
[tex]=\frac{64}{3(v^(^-^1^)^(^-^1^))}[/tex]
[tex]=\frac{64}{3v^1}[/tex]
[tex]=\frac{64}{3v}[/tex]
Angela has a rectangular piece of paper and cuts a rectangle out of a corner what are the area and perimeter of the resulting shape help me find the perimeter only
The perimeter of a shape is the summation of the visible lengths of the shape. The area; however, is the product of the length and the width of the shape
The perimeter of the figure is 74cm and the area of the figure is 231 square cm
I've added shape as an attachment.
The perimeter is the sum of all side lengths. So, we have:
[tex]Perimeter = 6cm + 7cm + 15cm + 9cm + 21cm + 16cm[/tex]
[tex]Perimeter = 74cm[/tex]
To calculate the area, we split the shape into 2.
The first has the following dimension:
[tex]Length = 6cm[/tex]
[tex]Width = 7cm[/tex]
While the second has the following dimension
[tex]Length = 21cm[/tex]
[tex]Width = 9cm[/tex]
The area of the shape is:
[tex]Area = 6cm \times 7cm + 21cm\times 9cm[/tex]
[tex]Area = 231cm^2[/tex]
Hence, the shape has a perimeter of 74cm and an area of 231 square cm

Doubling both the area of the bases and the height of a prism doubles its volume. T/F
Answer:
True.
Step-by-step explanation:
Answer: False
==========================================================
Explanation:
Let's consider a prism that has dimensions of
L = 3 ft W = 4 ft H = 5 ftand we'll say that the base is a rectangle with length L and width W. The area of the base is L*W = 3*4 = 12 sq ft. The volume of this prism is L*W*H = 3*4*5 = 60 ft^3
If we double the area of the base, then we go from 12 ft^2 to 24 ft^2. If we double the height, then we go from 5 ft to 10 ft.
The new volume of this larger prism is (area of base)*(height) = (24)*(10) = 240 ft^3
The jump from 60 ft^3 to 240 ft^3 is not "times 2". Instead, the multiplier is 240/60 = 4. This example shows that the volume has been quadrupled.

Answer:
a(n)= 1/2 * (-8) n-1
Step-by-step explanation:
In a geometric sequence, the ratio between successive terms is constant. This means that we can move from any term to the next one by multiplying by a constant value. Let's calculate this ratio over the first few terms:
\dfrac{-256}{32}=\dfrac{32}{-4}=\dfrac{-4}{\frac12}=\blue{-8}

We see that the constant ratio between successive terms is \blue{-8}−8start color #6495ed, minus, 8, end color #6495ed. In other words, we can find any term by starting with the first term and multiplying by \blue{-8}−8start color #6495ed, minus, 8, end color #6495ed repeatedly until we get to the desired term.
Let's look at the first few terms expressed as products:
nn 111 222 333 444

We can see that every term is the product of the first term, \red{\dfrac12}

start color #df0030, start fraction, 1, divided by, 2, end fraction, end color #df0030, and a power of the constant ratio, \blue{-8}−8start color #6495ed, minus, 8, end color #6495ed. Note that this power is always one less than the term number nnn. This is because the first term is the product of itself and plainly 111, which is like taking the constant ratio to the zeroth power.
Thus, we arrive at the following explicit formula (Note that \red{\dfrac12}

start color #df0030, start fraction, 1, divided by, 2, end fraction, end color #df0030 is the first term and \blue{-8}−8start color #6495ed, minus, 8, end color #6495ed is the constant ratio):

Answer:
There are 3 intervals as following:
x ≤ 1
-(x - 1) - (x - 3) = 2-2x + 4 = 22x = 2x = 11 ≤ x ≤3
(x - 1) - (x - 3) = 22 = 2, any value of x in the same intervalx ≥ 3
(x - 1) + (x - 3) = 22x - 4 = 22x = 6x = 3Combining the all, we get:

Step-by-step explanation:
Hi there!
Vertex form: [tex]y=a(x-h)^2+k[/tex] where [tex]a[/tex] is a scale factor and [tex](h,k)[/tex] is the vertex of the parabola
On the graph, we can determine that the vertex of this parabola is (3,1). Plug this into [tex]y=a(x-h)^2+k[/tex]:
[tex]y=a(x-3)^2+1[/tex]
The value of a must either be -1 or 1 because the graph has not been stretched or compressed vertically. How can we tell? Well, starting from the vertex, if we increase x by 1, y only changes by 1. If we decrease x by 1 starting from the vertex, y only changes by 1. This wouldn't be the case if the graph had been stretched or compressed.
Now, because this is a downward-facing parabola, we know that the value of a is negative. Because a can only be -1 or 1, a is therefore -1. Plug this into [tex]y=a(x-3)^2+1[/tex]:
[tex]y=-(x-3)^2+1[/tex]

Hi, Laura! ;)
The answer to the first question is 5,62.Here is the step by step solution:They want to know the center of a distribution. Another word for center is middle. When you have a set of numbers, you can find the middle by calculating the mean, the "average" of the data set.
1) Add all the numbers: 12,8 + 5,7 + 7,9 + 1,3 + 3,2 + 2,8 = 33,7
2) Divide the sum by the quantity of numbers, which is 6: 33,7 / 6 = 5,616
The closest number to 5,616 is 5,62.
==========================================================
Now let's answer your second question.
The correct answer is, indeed, 0,14.How do we get to this number? Here is the step by step solution:1) First step is to find out how many possible outcomes you have. It is the
number of raffle tickets in the box: 200.
2) Then, let's define the number of tickets that are prizes: 4 + 8 + 16 = 28.
The probability of selecting a prize ticket is the number of prize tickets divided by all the raffle tickets in the box: 28 / 200 = 0,14.
