Given cosθ= -[tex]\frac{7}{9}[/tex] and tanθ<0, find sin2θ
[tex] \sin {}^{2} (x) + {cos}^{2} (x) = 1[/tex]
[tex] {sin}^{2} (x) = 1 - {cos}^{2} (x)[/tex]
[tex] {sin}^{2} (x) = 1 - ({ \frac{ - 7}{9} })^{2} \\ [/tex]
[tex] {sin}^{2} (x) = 1 - \frac{49}{81} \\ [/tex]
[tex] {sin}^{2} (x) = \frac{81}{81} - \frac{49}{81} \\ [/tex]
[tex] {sin}^{2} (x) = \frac{32}{81} \\ [/tex]
[tex] \sin(x) = ± \sqrt{ \frac{32}{81} } \\ [/tex]
_____________________________________________
[tex] \tan(x) < 0 \: \: \: and \: \cos(x) < 0[/tex]
Thus :
[tex] \sin(x) > 0[/tex]
So we have :
[tex] \sin(x) = + \sqrt{ \frac{32}{81} } \\ [/tex]
[tex] \sin(x) = \frac{ \sqrt{16 \times 2} }{ \sqrt{9 \times 9} } \\ [/tex]
[tex] \sin(x) = \frac{4 \sqrt{2} }{9} \\ [/tex]
_____________________________________________
[tex] \sin(2x) = 2 \times \sin(x) \times \cos(x) [/tex]
[tex] \sin(2x) = 2 \times \frac{4 \sqrt{2} }{9} \times ( - \frac{7}{9} ) \\ [/tex]

2 3/10x-5/7y-4 5/6y-2 4/5x please help and simplify
Answer:
-1/2x -(5 23/42)y
Step-by-step explanation:
We assume you want to simplify the expression ...
(2 3/10)x -(5/7)y -(4 5/6)y -(2 4/5)x
__
The mixed numbers and fractions are combined in the usual way. A common denominator needs to be found for the addition or subtraction to take place.
= x(2 3/10 -2 4/5) -y(5/7 +4 5/6)
= x(23/10 -28/10) -y(30/42 +4 35/42)
= x(-5/10) -y(4 65/42)
= -1/2x -(5 23/42)y

Answer:
See below ~
Step-by-step explanation:
Part (a) :
Formula : Perimeter = 2 (Length + Width)⇒ 278 = 2(54 + Length)⇒ 139 = 54 + LengthLength = 139 - 54 = 85 mPart (b) :
Formula : Area = Length × Width⇒ 8811 = 99 x Width⇒ Width = 8811/99Width = 89 cmAnswer:
(a) The length is 85 m.
(b) The width is 89 cm.
Step-by-step explanation:
(a)
Perimeter (P) formula using the length (L) and width (W) of a rectangle.
P = 2L + 2W
P = 278 m
W = 54 m
278 = 2L + 2(54)
2L + 108 = 278
2L = 170
L = 85
Answer: The length is 85 m.
(b)
Area (A) formula using the length (L) and width (W) of a rectangle.
A = LW
A = 8811 cm²
L = 99 cm
8811 = 99 × W
W = 8811/99
W = 89
Answer: The width is 89 cm.

Bob Travled 60 miles every 1 hour he was on the road wich graph represents y the total number of miles driven x hours?
Answer:
Step-by-step explanation:
Find the area of the shaded region. Express your answer in terms of \piπ and do not round any numbers.
Answer:
The strategy is to find out the total area and find the area of the 3 circles then subtract the sum of the circles' are from the total area
Total area = (length * width) = ( 3+6+9+12) * 18 = 540 sq. inch
3 Circles area = πr₁² + πr₂² + πr₃²
r₁= 12/2 = 6 in r₂ = 9/2 = 4.5 in r₃ = 6/2 = 3 inπr₁² + πr₂² + πr₃²
π(6²) + π(4.5)² + π(3)²
= 36π + 20.25π + 9π
= 65.25π
Shaded area = 540 - 64.25π = 335.011 sq. in

equation of the new function?
A. g(x) = x
O B. g(x) = 7x
x
O c. g(x) = x - 7
D. g(x) = x+7
awnser
The correct answer is C. f(x) = x - 7
Step-by-step explanation:
In order to find this, you simply need to know that vertical shifts can be added on to the end of parent equations as constants. Since this is a downward shift, we use a negative number.

Find the new dimensions of the figure given at right when it is enlarged by scale factor of 2.5 then find the perimeter and area of the original and enlarge it figure
The perimeter and area of the original are 20 ft and 23.5 square ft and the enlarged figure are50 ft and 146.875 square ft.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The figure is the combination of a triangle and a square.
The area of the original (A₀) figure will be
[tex]\rm A_o = \dfrac{1}{2} \times 3 \times 5 + 4 \times 4\\\\A_o = 23.5 \ ft^2[/tex]
The perimeter of the original figure (P₀) will be
[tex]\rm P_o = 3 + 5 + 4 + 4 + 4\\\\P_o = 20 \ ft[/tex]
The scale factor is 2.5.
Then the dimension of the triangle will be
h = 2.5 × 3 = 7.5 ft
b = 2.5 × 5 = 12.5 ft
Then the dimension of the square will be
a = 2.5 × 4
a = 10 ft
The area of the new figure will be
[tex]\rm A = \dfrac{1}{2} \times 7.5\times 12.5 + 10*10\\\\ A = 146.875 \ ft^2[/tex]
The perimeter of the new figure will be
[tex]\rm P= 7.5 + 12.5 + 10+ 10+ 10\\\\P = 50 \ ft[/tex]

Answer:
To find the perimeter of an enlarged figure, you can multiply the original figure’s perimeter by the scale factor. You could also multiply each dimension of the original figure by the scale factor to find the dimensions of the enlarged figure, and then add to find the perimeter.

Write the sequences equation for the table . Your equation should be in the form a(n)=man+b
Answer:
a(n) = 3.25n + 1.25Step-by-step explanation:
7.75-4,5 = 3.25
11-7.75 = 3.25
14.25-11 =3.25
17.5-14,25 = 3.25
It’s clear that this is an arithmetic sequence with common difference of 3.25
The equation form of such sequence is a(n) = a×n + b ,where ‘a’ is the common difference.
Then
a = 3.25
The first term a₁ = 4.5
On the other hand, a₁ = 3.25 ×(1) + b
Then
4.5 = 3.25 ×(1) + b
Then
b = 4.5 - 3.25 = 1.25
Conclusion:
a(n) = 3.25n + 1.25

Mean = sum of the numbers / 10

The median is the middle number in the ordered list, or if there are an even number of values, the mean of the 2 middle numbers. There are 10 numbers here, so the median = (84+84)/2 = 84
Median = 84.
The mode is the value that occurs most. Here we have 2 84's so
Mode = 84.

topic: Inscribed Quadrilateral theorem in a Circle
Answer:
Step-by-step explanation:
Problem 12
Comment
A cyclic quadrilateral (a 4 angled quadrilateral where all 4 corners touch the circumference of a circle), has the property that opposite angles add up to 180 degrees.
Formula
4x + 9 + 3x + 3 = 180 Collect like terms
Solution
4x + 3x + 9 + 3 = 180 Combine
7x + 12 = 180 Subtract 12 from both sides
7x + 12 -12 = 180 - 12 Combine
7x = 168 Divide by 7
7x/7 = 168/7
x = 24
Answer
x = 24

Comment
Same comment as was given for problem 12
Formula
3x + 2 + 3x - 32 = 180 Collect like terms
Solution
3x + 3x +2 - 32 = 180 Combine
6x - 30 = 180 Add 30 to both sides
6x -30+30 = 180 + 30
6x = 210 Divide by 6
6x/6 = 210/6
x = 35

4x + 9 + 3x + 3 = 180°
COMBINE the LIKE TERMS
(4x + 3x) = (9 + 3) = 180°
4x + 3x + 9 + 3 = 180°
7x + 12 = 180°
SUBTRACT 12 to BOTH SIDES
7x + 12 - 12 = 180 - 12

The equation of the line which passes through the point (3, 7) and has a gradient of 3 is:
Answer:
y = mx + b, where m is gradient and b is y-intercept
y = 3
y = 3x + b
To find b use the coordinate (3, 7) to find b
7 = 3(3) + b
b = 7 - 9
b = -2
Therefore, the equation will be:

please help i have to write and i dont understand
Answer:
A. This is a vertical angle set. As you can see, they are cut by the transversal and have the exact same interior angle, so it is a vertical angle.
B. Since these too are vertical angles, all you have to do is just put each expression on the sides of an equation like so:
5y-29=3y+19
Once you do this, you just need to simplify the equation by putting like terms together, and then you will find the solution for y, which is 24.
C. We know that the solution for y is 24, so we need to plug it into the equation to find, the angle, so if we do 3*24-19, we get 53, so we need to subtract that from 180 degrees, which is the total angle of the straight line, then we can get 127 degrees, which is what angles <7 and <8 are.
