Find sin A, cos A, tan A. Express each ratio as a fraction. a=9, b=41, c=40
Answer:
sin A = 9/41
cos A = 40/41
tan A = 9/40
Step-by-step explanation:
sin A = opp/hyp = a/b = 9/41
cos A = adj/hyp = c/b = 40/41
tan A = opp/adj = a/c = 9/40

If a new sweater sells for $53 find the total cost if you are charged 5% sales tax. Round your answer to the nearest cent
Answer:
$55.65
Step-by-step explanation:
you would find 5% of 53 which is $2.65 and then add that to your original price so 53 + 2.65 = 55.65
a scatter plot with a line is shown.
(pic)
which statement is most likely correct about the line?
1) it can be the line of best fit because it is closest to most data points
2) it can be the line of best fit because it passes through all the scatter points
3) it cannot be the line of best fit because it is not closest to most of the points
4) it can be the line of best fit because it does not show positive association
Answer:
Choice 3
Step-by-step explanation:
A line of best fit always goes through the pattern of points.

Answer:
A)x^2-x-6
B)2x^2-12x+12
C)x^2-4
Step-by-step explanation:
A) Lets break this problem into portions the first part we trying to distribute is x(x-3)
X times X is X^2 and X times 3 is 3x so x^2-3x
Lets work on the second part
2(x-3)
2 times x =2x and 2 times -3 = -6 so 2x-6
And since you are supposed to add them its 2x-6+x^2-3x
x^2 can't be combined so that is seperate but 2x(+)-3x (negative overpowers positiveis) so we have -x and then -6 cant be joined with anything so
x^2-x-6
B) I'm going to go a little faster but it's essentially the same
2x(x-4)-3(x-4)
Multiply2x*x= 2x^2
2x*-4=-8x
combinde these two (2x^2-8x)
Pt.2
-3*x= -3x
-3*-4(negative and negative cancels out and it becomes positive)=12
join (-3x+12)
and then 2x^2-8x-3x+12
you can only combine -8x-3x so -12x
2x^2-12x+12
C) this is level 3
x(x-2) + 2(x-2)
(x^2-2x) +(2x-4)
only like terms is 2x and-2x so combine and its 0
x^2-4
2x + 3y = 13
x - 3y = 2
Answer:
use the 2nd equation to find that x=3y+2 and now plug it into the first equation to get 2(3y+2)+3y=13 distribute to get 6y+4+3y=13, reorganize the equation by adding common integers to become 9y+4=13, Subtract 4 from both sides to get 9y=13-4, or 9y=9, so y=1, plug that into the equation for x to get x=3+2, so y=1 and x=5

Which expression is NOT equivalent to −6×(13+13)? −63+13 −6×23 −6×(2×13) (13+13)×(−6)
Answer:
I know that -63+13= -50
(-6) * 23 = (-138) are NOT equivalent, the only expressions that are equivalent are (13+13)x(-6) and -6x(2x13) they both equal to -156 which is to say -6x(13+13) Are the same

Step-by-step explanation:
oh law of sines soo sin(A) / a = Sin(B) / b
2a)
here DE = side f then let's find that side with law of sines and plug side f in as 'a' in law of sines , so
Sin(28) / a = Sin(54) / 31 ( where a = f = DE )
can you do the algebra here Emily? or do you want me to show that?
Sin(28) *31 / Sin(54) = a
17.989 =a
18.0 =a (rounded to nearest 10th)
DE = 18.0 m
2b)
find RT where RT = side a
since they give use 2 of the other sides of the triangle we can quickly figure out the S angle. 180 = 71+62+S so S = 47° ( I'm going kinda fast b/c I don't know how much time you have :? )
then Sin(A) /a = Sin(B) / b
Sin(47) / a = Sin(62) / 29
Sin(47) *29 / Sin(62) = a
24.020 = a
RT = 24.0 meters ( rounded to nearest 10th )
2c)
they want us to find ∠X with law of sines soo
I'll just use the letter they give us for variables
Sin(X) / x = Sin(Y ) / y
Sin(X) = x* Sin(y) / y
X = arcSin [ 14 * Sin(108) / 34 ]
X = arcSin [ 0.3916115]
X = 23.0548°
X= 23° ( rounded to nearest degree )
2d)
they ask us to find ∠E
I'll , again, use the letter they give us for variables
Sin(E) / e = Sin( F ) / f
Sin(E) / 18 = Sin(78) / 30
E = arcSin[ 18 * Sin(78) / 30 ]
E = arcSin [ 0.5868856 ]
E = 35.936 °
E = 36 ° ( rounded to nearest degree )

The chords intersect at point U.
A circle is shown. Chords R T and Q S intersect at point U. The length of R U is 12 centimeters, the length of U T is 4 centimeters, the length of U S is y centimeters, and the length of Q U is 8 centimeters.
What is the value of y?
2
4
6
8
Answer:
Its b)6
Step-by-step explanation:
I just did it on edge and got it correct
The value of y is 6 centimeters.
Given that,
The length of RU = 12 centimeters
The length of UT = 4 centimeters
The length of QU = 8 centimeters.
The length of US = y centimeters
What is the intersecting chords theorem?The intersecting chords theorem states that, the product of one whole chords segment and its external segment is equal to the product of the other whole chords segment and its external segment when two chords cross at an exterior point.
According to the intersecting chords theorem,
US x QU = RU x UT
Substitute the values in above formula,
y x 8 = 12 x 4
y = 48/8
y = 6 centimeters,
Hence, the value of y is 6 centimeters.
