The unit circle is a circle with radius 1 centered at the origin of the Cartesian Plane. In a pair of coordinates (x,y) on the unit circle x2+y2=1, coordinate x is the cosine of the angle formed by the point, the origin, and the x-axis. Coordinate y is the sine of the angle.

Csc(tan^1 square root 17 divided by 8)
Please help fast!!!
Answer:
Option D
Step-by-step explanation:
We have that:
csc(x) = 1/sin(x)
Then:
csc( tan(√(17)/8)^-1 )
To use the inverse tangent function, you can go to the "inv" button in your calculator, and then use go to the "tan" button.
This is equal to:
= csc( 27.26°)
= csc(27.26°)
= 1/sin(27.26°) = 2.18
And we know that:
(9*√17)/17 = 9/√17 = 2.18
Then the correct option is D.

[tex]\boxed {\boxed {\sf (4,3) \ is \ not \ a \ solution}}[/tex]
Step-by-step explanation:
If we want to test a solution, we can plug it into the equations and see if it checks out.
We are given the point (4,3). Since points are written (x,y)...
x=4 y=3Substitute the values into the first equation.
[tex]11x+9y=17 \\11(4)+9(3)=17[/tex]
Multiply.
[tex]44+ 27=17\\[/tex]
Add.
[tex]71 \neq 71[/tex]
This does not check out, so we automatically know this point doesn't work. However, we can check the other equation.
[tex]x+y=7 \\4+3=7\\7=7[/tex]
Even though the second equation works, BOTH have to work because this is a system of equations. Therefore, (4,3) is not a solution.

You and your friend got tricked into helping another friend move stuff from a garage into moving truck. The ramp used is 12 feet long and makes a 36° angle with the horizontal ground. You discover that the incline is just too steep, so you replace the ramp with one that is 32 feet long. What angle does this replacement ramp make with the ground? Round your answer to the nearest tenth of a degree
Answer:
12.73 Degrees
Step-by-step explanation:
I'm going to assume some things. The height of the truck is not changing, i.e. the the distance and length of the ramp is but the height stays the same.

[tex]12 \sin(36) = a \\ a = 7.05342302750[/tex]

Answer:
y-25=180
Step-by-step explanation:
Same line so 180 degrees.
Answer: D or “y + 25 = 180”
a straight line is 180 degrees, therefore the combination of two angles should equal 180.
With that being said the answer should be y plus 25 = 180!
to find y, flip the equation: 180 - 25 = 155. Therefore y = 155 :)

For each line, determine whether the slope is positive, negative, zero, or undefined. Line 1 Line 2 Line 3 Line 4 Positive O Negative O Zero O Undefined O Positive O Negative Zero O Undefined Positive Negative Zero O Undefined O Positive Negative Zero O Undefined Х $ ? Continue o Type here to search ㅇ
Answer:
Line 1: zero
Line 2: negative
Line 3: undefined
Line 4: positive
Step-by-step explanation:
Line 1 => slope is horizontal. The slope of horizontal lines are always equal to 0. Therefore, the slope of line 1 is zero.
Line 2 => the line slants downwards form our left to the right, this implies there is a decline or increase. Thus, the slope would be negative.
Line 3 => the line of a vertical line is always undefined. Line 3 slope is therefore undefined.
Line 4 => the slope slants upwards from our left to the right. This indicates a rising slope or an increase. Therefore, the slope of line 4 is positive.

Julio invests $6,100 into an account that earns 5.2% annual compound interest. If Julio makes no additional deposits or withdrawals, which best represents the amount of interest Julio will earn after 8 years?
A $15,250.73
B $2,120.73
C $3050.73
D $9150.73
D) $9150.73
Step-by-step explanation:
Simple compound irate =
principal*growth rate^years
or
V(t) = p*g^t
Where g = 100% + the given growth rate,
in this case, 5.2%
So,
V(8) = 6,100*1.052^8
V(8) = 9150.73
Find AB, B equal 44° C equals 53° and b equals 7
Answer:
Step-by-step explanation:
Remark
I take it you are studying the sine law. If that is so, Then it will be set up as
Formula
x/sin(53) = 7 / sin(44) Multiply both sides by Sin(53)
Solution
Sin(53)x/Sin(53) = 7 sin(53)/Sin(44)
x = 7*Sin(53)/Sin(44)
x = 7 * 0.7986/0.6947
x = 8.0848
Note:
The sine law is always set up by 2 ratios. It consists of the sine of an angle divided by the side opposite = equal to another angle's sine over the side oppose the second angle.
The sine law can also be set up as two ratios side opposite / sin(Angle).

What is the value of g(4-1))?
A.
2
B.
00
C.
22
D.
48
Answer:
g(f(-1)) = 48
Step-by-step explanation:
given the following
f(x) = 5x² + 2
g(x) = x²-1
g(f(x)) = g(5x²+2)
Replace x with 5x² + 2 in g(x) as shown;
g(5x²+2) = (5x²+2))²- 1
g(f(x)) = (5x²+2))²- 1
g(f(-1)) = (5(-1)²+2))²- 1
g(f(-1)) = (5+2))²- 1
g(f(-1)) = (7)²- 1
g(f(-1)) = 49 - 1
g(f(-1)) = 48

the cost of 5kg of potatoes is 3.60£ the cost of 1/2 kg of carrots is 31p. Work out the cost of 13kg of potatoes and 21/2 of carrots
Answer: 13kg potatoes=9.36 2.5 of carrots=155p
Step-by-step explanation:
potatoes 5kg=3.6 carrots .5kg=31p
value of each kg of potatoes is...
[tex]\frac{3.6}{5} =.72[/tex]
so
[tex]13*.72=9.36[/tex]
value of each kg of carrots is...
31x2=62
so (I assumed when you typed 21/2 it meant 2 1/2 or 2.5)
2.5x62=155
The cost of 13 kg of potatoes is $ 9.36
The cost of 2 1/2 kg of carrots is $ 155p
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 5 kg of potatoes be = $ 3.60
Let the cost of 1/2 kg of carrots be = 31p
Now , the equation is
The cost of 1 kg of potatoes = cost of 5 kg of potatoes / 5
= 3.60 / 5
= $ 0.72
So ,
The cost of 13 kg of potatoes is = 13 x cost of 1 kg of potatoes
= 13 x 0.72
= $ 9.36
Now , the equation is
The cost of 1 kg of carrots = cost of 1/2 kg of carrots x 2
= 31 x 2
= 62p
The cost of 2 1/2 kg of carrots is = 2 1/2 x cost of 1 kg of carrots
= 2 1/2 x 62
= 155p
Therefore , the cost of 13 kg of potatoes is $ 9.36 and cost of 2 1/2 kg of carrots is $ 155p
Hence ,
The cost of 13 kg of potatoes is $ 9.36
The cost of 2 1/2 kg of carrots is $ 155p
