Find value of x
Find value of y
Answer:
Step-by-step explanation:
use SOH CAH TOA
Sin = Opp / Hyp
Cos = Adj / Hyp
Tan = Opp / Adj
then we know the adjacent side and the angle, and want to find the Hyp, so use CAH
Cos(60) = ( 8[tex]\sqrt{3}[/tex] / 3 ) / Hyp ( cos(60) = 1/2 )
Hyp = (8[tex]\sqrt{3}[/tex] / 3) / (1/2)
Hyp = 2 ((8[tex]\sqrt{3}[/tex] / 3)
Hyp = 16[tex]\sqrt{3}[/tex] / 3
x = 16[tex]\sqrt{3}[/tex] / 3
Now use SOH
Sin (60) = Opp / 16[tex]\sqrt{3}[/tex] / 3 ( sin(60) = [tex]\sqrt{3}[/tex]/2 )
(16[tex]\sqrt{3}[/tex] / 3)([tex]\sqrt{3}[/tex]/2) = Opp
16 * 3 / 6 = Opp
8 = Opp
y = 8

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

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

Tyler is designing a banner that will welcome people to a festival. The design for the banner has an
area of 1.5 square feet. The actual banner will be a dilation of the design by a factor of 5. What will
the area of the actual banner be?
Answer:
7.5 sq ft
Step-by-step explanation:
1.5*5=7.5
The design is 1/5 of the actual size, so you just multiply by 5 to get the real size.
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?

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.

The graph of a twice differential function is shown at right. Which of the following is true?
Answer:
(C)
Step-by-step explanation:
looking from the slope: f'(2) is negative
f(2)=0
the curve concave upward: f''(2) is positive
f'(2)<0
f(2)=0
0<f''(2)
f'(2)<0<f''(2)
The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.
What is a differential function?A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.
Given:
The coordinate of the graph is shown in figure (2, 0),
As we can see from the graph, the slope: f' (2) is negative (Downwards)
Again, from the graph
f(2) = 0
Thus, the curve concave upward: f'' (2) is positive (upward)
f' (2)<0
f (2)=0
0 < f'' (2)
f' (2) < 0 < f'' (2)
Therefore, f' (2) < 0 < f'' (2) is true in the given graph.

how do movement skills in volleyball transfer to tennis?
Answer:
Tennis – It's not difficult to see that tennis and volleyball have their similarity; both involve hitting a ball over the net in the hope that the opponent won't be able to return it. Much like tennis, volleyball requires short and explosive movements and cat-like reflexes, rather than long runs down a pitch.
