Answer: [tex]-\frac{240}{289}[/tex]
=========================================================
Explanation:
Use the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] and plug in the fact that [tex]\cos(\theta) = \frac{8}{17}\\\\[/tex]
Isolating sine leads to [tex]\sin(\theta) = -\frac{15}{17}\\\\[/tex]. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
[tex]\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\[/tex]
What is the equation of a line that has a slope of One-half and passes through point (2, –3)?
Answer: y = one-half x minus 4
Step-by-step explanation:
y = 1/2 x + b
-3 = 1/2 (2) + b
-3 = 1 + b
-3 - 1 = b
-4 = b

Answer:
25 fl oz
Step-by-step explanation:
1 pint is equivalent to 16 fl oz, so we're left with 25 fl oz and 16 fl oz. As you can see, 25 is greater than 16, making 25 fl oz the correct answer.
3. Subtract
x)--5x2 + x-2
g(x) = -3x2 + 3x + 9 9
Step-by-step explanation:
For example: Subtract 4x - 10y + 15z from 5x + 8y - 20z.
Step 1: Arrange the polynomials in standard form. In this example, it is already arranged.
Step 2: Place them horizontally.
(4x - 10y + 15z) - (5x + 8y - 20z)
Step 3: Change the sign of the second polynomial through the parentheses.
4x - 10y + 15z - 5x - 8y + 20z
Step 4: Arrange the like terms together.
4x - 5x - 10y - 8y + 15z + 20z
Step 5: Solve the equation
-x - 18y + 35z
Therefore, when we subtract 4x - 10y + 15z from 5x + 8y - 20z = -x - 18y + 35z.

Distance between -3,-2 and 5,2
We can find the distance between two points by using distance formula,
[tex] \qquad \: D = \sf \red{\sqrt{ {(x_2 -x_1)}^{2} + {(y_2 -y_1)}^{2} }}[/tex]
Here,
x₁ = -3
x₂ = 5
y₁ = -2
y₂ = 2
Therefore,
[tex] : \implies \: D = \sf \red{\sqrt{ {(x_2 -x_1)}^{2} + {(y_2 -y_1)}^{2} }} \\ \\ : \implies \: D = \sf \sqrt{ {(5-( - 3))}^{2} + {(2 -( - 2))}^{2} }
\\ \\ : \implies \: D = \sf \sqrt{ {8}^{2} + {4}^{2} } \\ \\ : \implies \: D = \sqrt{64 + 16}
\\ \\ : \implies \: D = \sqrt{80} [/tex]
Hence the √80 = 8.94 approx is the distance between the two points (-3,-2) and (5,2).
To find :-
The distance between 2 points
Given :-Here we have been provided 2 points
(-3, -2) and (5, 2)
Solution :-[tex] (x_1,y_1) = (-3,-2) \\ (x_2,y_2) = (5,2) [/tex]
Formula to find distance is
[tex] = \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } [/tex]
[tex] = \sqrt{ {(5 - ( - 3))}^{2} + {(2 - ( - 2))}^{2} } \\ = \sqrt{ {(8)}^{2} + {(4)}^{2} } \\ = \sqrt{64 + 16} \\ = \sqrt{80} \\ = 4 \sqrt{5} [/tex]
Result :-The distance between 2 points is 4√5.

Fred is baking cookies for a school
bake sale. It takes
2/3 of a cup of
sugar to
make one batch of
cookies. How many cups
of sugar
does he need to double the
recipe?
Answer: Fred needs 4/3 a cup of sugar, which can be simplified into 1 1/3.
Step-by-step explanation:
If you do 2/3 times 2/1 (because double means twice the amount) you will get 4/3, which again, can be simplified into 1 1/3.
There are 114 cans of soup in a grocery store. The ratio of large cans of soup to small cans of soup is 12:7. A customer buys 2 large cans of soup. What is the new ratio of large cans of soup to small cans of soup in the grocery store? Choose all the correct answers. A. 3:5 B. 5:3 C. 8:5 D. 10:7 E. 35:21 F. 37:21
The ratio of the large cans to small cans shows the distribution of both cans
The new ratio of large cans of soup to small cans of soup in the grocery store is (b) 5 : 3 and (e) 35: 21
How to determine the ratio?The given parameters are:
Ratio = 12 : 7
Rewrite as:
Large : Small= 12 : 7
The number of cans is given as:
Can = 114
So, the distribution of the cans are:
Large = 12/(12 + 7) * 114
Large = 72
Small = 7/(12 + 7) * 114
Small = 42
When 2 large cans are purchased, the remaining number of cans are:
Small = 42
Large = 70
Express as ratio
Large : Small = 70 : 42
Simplify
Large : Small = 35 : 21
Large : Small = 5 : 3
Hence, the new ratio is (b) 5 : 3 and (e) 35: 21

The sum of the first 10 terms of an arithmetic series is 100 and the sum of next 10 300 .Find the series.
Let a be the first term in the sequence, and d the common difference between consecutive terms. If aₙ denotes the n-th term in the sequence, then
a₁ = a
a₂ = a₁ + d = a + d
a₃ = a₂ + d = a + 2d
a₄ = a₃ + d = a + 3d
and so on, up to the n-th term
aₙ = a + (n - 1) d
The sum of the first 10 terms is 100, and so
[tex]\displaystyle \sum_{n=1}^{10} a_n = 100 \\ \sum_{n=1}^{10} (a + (n-1)d) = 100 \\ (a-d) \sum_{n=1}^{10} 1 + d \sum_{n=1}^{10} n = 100 \\ 10a+45d = 100[/tex]
where we use the well-known sum formulas,
[tex]\displaystyle \sum_{n=1}^N 1 = 1 + 1 + 1 + \cdots + 1 = N[/tex]
[tex]\displaystyle \sum_{n=1}^N n = 1 + 2 + 3 + \cdots + N = \frac{N(N+1)}2[/tex]
The sum of the next 10 terms is 300, so
[tex]\displaystyle \sum_{n=11}^{20} a_n = 300 \\ (a-d) \sum_{n=11}^{20} 1 + d \sum_{n=11}^{20} n = 300 \\ (a-d) \left(\sum_{n=1}^{20} 1 - \sum_{n=1}^{10} 1\right) 1 + d \left(\sum_{n=1}^{20} n - \sum_{n=1}^{10} n\right) = 300 \\ 10a+145d = 300[/tex]
Solve for a and d. Eliminating a gives
(10a + 145d) - (10a + 45d) = 300 - 100
100d = 200
d = 2
and solving for a gives
10a + 145×2 = 300
10a = 10
a = 1
So, the given sequence is simply the sequence of positive odd integers,
{1, 3, 5, 7, 9, …}
given recursively by the relation
[tex]\begin{cases}a_1 = 1 \\ a_n = a_{n-1} + 2 & \text{for }n>1\end{cases}[/tex]
and explicitly by
[tex]a_n = 1 + 2(n-1) = 2n - 1[/tex]
for n ≥ 1.

graph of F(x), shown below, has the same shape as the graph of G(x) = x4, but it is shifted 4 units to the right. What is its equation?F(x) = _____
Answer:

Step-by-step explanation:
The equation of the graph of f(x) which is formed by shifting 4 units to the right of g(x) is f(x) = (x - 4)⁴
What is Translation of Functions?Translation of functions is defined as the when each point in the original graph is moved by a fixed units in the same direction.
There are horizontal translation and vertical translation of functions.
Given a function G(x).
G(x) = x⁴
A function F(x) is formed by shifting the graph of G(x) to the right by 4 units.
A function h(x) when shifted to the right by k units becomes h(x - c).
So the graph of G(x) when shifted to the right by 4 units becomes G(x - 4).
G(x - 4) = (x - 4)⁴
So, F(x) = (x - 4)⁴
Hence the function is F(x) = (x - 4)⁴.

Tickets to a baseball game cost $3 for a child’s ticket and $5 for an adult ticket. At the last game, $521 was collected when 139 people attended the game. Which value could replace x in the table so that a single-variable equation can be written and solved to determine the number of child’s tickets, c, sold?
Answer:
x = 52, c = 87
Step-by-step explanation:
Set up and then solve this system of equations:
3c + 5x = 521--->3c + 5x = 521
c + x = 139 --->3c + 3x = 417

Step-by-step explanation:
To multiply polynomials, simply distribute whatever's outside the largest set of parenthesis, then combine like terms.
1) Distribute the parenthesis (x + 6):
x(4x² + 2x - 8) + 6(4x² + 2x - 8)
4[tex]x^{3}[/tex] + 2x² -8x + 6(4x² + 2x -8)
4[tex]x^{3}[/tex] + 2x² -8x + 24x² + 12x - 48
Combine like terms:
4[tex]x^{3}[/tex] + 26x² + 4x - 48
2) Distribute the parenthesis (x - 8):
x(2x² - 7x + 4) + (-8)(2x² - 7x + 4)
2[tex]x^{3}[/tex] - 7x² + 4x + (-8)(2x² - 7x + 4)
2[tex]x^{3}[/tex] - 7x² + 4x + -16x² + 56x - 32
Combine like terms:
2[tex]x^{3}[/tex] - 23x² + 60x - 32
3) Distribute the parenthesis (x + 2):
x([tex]x^{4}[/tex] + 7x² - 4) + 2([tex]x^{4}[/tex] + 7x² - 4)
[tex]x^{5}[/tex] + 7[tex]x^{3}[/tex] - 4x + 2([tex]x^{4}[/tex] + 7x² - 4)
[tex]x^{5}[/tex] + 7[tex]x^{3}[/tex] - 4x + 2[tex]x^{4}[/tex] + 14x² - 8
No like terms to combine, so:
[tex]x^{5}[/tex] + 7[tex]x^{3}[/tex] - 4x + 2[tex]x^{4}[/tex] + 14x² - 8
4) Distribute the parenthesis (x + 4):
x(2[tex]x^{6}[/tex] - 7[tex]x^{5}[/tex] + 3) + 4(2[tex]x^{6}[/tex] - 7[tex]x^{5}[/tex] + 3)
2[tex]x^{7}[/tex] - 7[tex]x^{6}[/tex] + 3x + 4(2[tex]x^{6}[/tex] - 7[tex]x^{5}[/tex] + 3)
2[tex]x^{7}[/tex] - 7[tex]x^{6}[/tex] + 3x + 8 [tex]x^{6}[/tex] - 28[tex]x^{5}[/tex] + 12
Combine like terms:
2[tex]x^{7}[/tex] + [tex]x^{6}[/tex] - 28[tex]x^{5}[/tex] + 3x + 12
