Given right triangle ABC.
To the nearest tenth of an inch, find the length of side c, the hypotenuse
13.7
1.7
14.6
1.8
Answer:
14.6
Step-by-step explanation:
For this case we have the following trigonometric relationship:
sine (x) = C.O / h
Where,
x: angle
C.O: opposite leg
h: hypotenuse
Substituting values we have:
sine (20) = 5 / c
Clearing c:
c = 5 / sine (20)
c = 14.619022
Rounding:
c = 14.6 in
Answer:
c = 14.6 in

Answer:
6. C multiply the first equation by -7 ...
7. A parallel lines
Step-by-step explanation:
6. The idea of elimination is to create equations that have opposite coefficients for one of the variables. In this set of equations, there are two simple ways to achieve that.
On is to multiply the second equation by -2 (so x-coefficients are 4 in the first equation and -4 in the second equation).
The other is to multiply the first equation by -7 (so y-coefficients are -7 in the first equation and +7 in the second equation).
This latter method is described in answer choice C.
__
7. Equations are more easily compared if they are in the same form. Here, "standard form" is nice. To put the second equation in standard form, we must remove a factor of 3 from all of the numbers:
3(2x) +3(y) = 3(4)
2x +y = 4
We see that this differs from the first equation only in that it has a different right-side constant. That means it describes a parallel line.

The end point P of a line segment PQ(-3,6) and its mid point is (5,8) Find the coordinates of the end point Q
Answer:
(13, 10)Step-by-step explanation:
Let Q have coordinates x and y
Using midpoint formula we find the values of x and y
(- 3 + x)/2 = 5 ⇒ -3 + x = 10 ⇒ x = 10 + 3 ⇒ x = 13(6 + y)/2 = 8 ⇒ 6 + y = 16 ⇒ y = 16 - 6 ⇒ y = 10Q = (13, 10)....................

1A) Quad ABCD is inscribed in the circle. Find x. *
Answer:
x = 34
Step-by-step explanation:
according to the problem ::
(2x + 9)° + (3x + 1)° = 180° [ since, the opposite angles of a cyclic quadrilateral are supplementary ]
or, 2x + 9 + 3x + 1 = 180
or, 2x + 3x = 180 - 10
or, 5x = 170
or, x = 170 / 5
or, x = 34
therefore, the value of x is 34°
hope that helped ..

If the perimeter of a square is 20, find the length of a diagonal. Round your answer to the nearest tenth.
7.7
7.1
6.3
8.4
Answer:
option 2] 7. 1
Step-by-step explanation:
Perimeter of square is 20.
therefore,
[tex]perimeter \: = 4 \times side \\ therefore \: 20 = 4 \times side \\ \: \: \: \: \: \: side = \frac{20}{4} \: = 5 [/tex]
the diagonal and the Two adjacent sides of the square form a right angle triangle, so,
By hypotenuse theorem,
[tex] {iagonal}^{2} \: = {side1}^{2} + {side2 }^{2} \\ \: \: \: \: \: \: \: \: = {5}^{2} + {5 }^{2} \\ = 25 + 25....(as \: suare \: has \: equal \: sides \: i.e \: 5) \\ = 50 \\diagonal = \sqrt{50} \\ = \sqrt{25 \times 2} \\ = 5 \sqrt{2 } \\ = 5 \times 1.414 \\ = 7.07 \\ = approx \: 7.1[/tex]
Review the proof of de Moivre’s theorem.
Proof of de Moivre's Theorem
[cos(θ) + i sin(θ)]k + 1
A = [cos(θ) + i sin(θ)]k ∙ [cos(θ) + i sin(θ)]1
B = [cos(kθ) + i sin(kθ)] ∙ [cos(θ) + i sin(θ)]
C = cos(kθ)cos(θ) − sin(kθ)sin(θ) + i [sin(kθ)cos(θ) + cos(kθ)sin(θ)]
D = ?
E = cos[(k + 1)θ] + i sin[(k + 1)θ]
Which expression will complete the proof?
Answer:
D
Step-by-step explanation:
Just took it.
Answer: D. cos(kθ + θ) + i sin(kθ + θ)
Step-by-step explanation:
The screenshot pretty much speaks for itself, but you can see that the proof ends with cos[(k + 1)θ] + i sin[(k + 1)θ]. That means that addition is happening in Step D, and that the expressions in the cosine and sine parts are the same. So, the correct option is D. Hope that helps!

The incenter of a triangle is the point of concurrency of the angle bisectors. Does a rectangle have an incenter?
9514 1404 393
Answer:
if and only if the rectangle is a square
Step-by-step explanation:
The angle bisectors of a rectangle will meet at a single point if, and only if, the rectangle is a square.
In general, a rectangle does not have an incenter.
__
The incircle must be tangent to all sides of the polygon. That cannot be the case unless the rectangle has its length equal to its width. That is, it must be a square.

Mary is comparing the costs from two companies of having a banquet
catered. Company M charges a base fee of $60 plus $12 per guest.
Company N charges a base fee of $120 plus $9 per guest. Let "Y" represent
the total cost and "x" represent the number of guests. Which system is the
best model of this situation?
Company M: y = 60x + 12 Company N: y = 120x + 9
Company M: 60 = 12x + y Company N: 120 = 9x + y
Company M: y = 12x + 60 Company N: y = 9x + 120
Company M: 12 = 60x + y Company N. 9 = 120x + y
Answer:
work it out
Step-by-step explanation:
Company M: y = 12x + 60 Company N: y = 9x + 120

Find the area of the shape.
Answer:
36*sqrt(3)
Step-by-step explanation:
Remark
Use the Pythagorean theory to find the height. Use that height to find the area of the rectangle and the triangle Or
You can find the area of the trapezoid which requires only 1 step after you find the height.
Height
c = 8
b = 4
a = ?
a^2 + b^2 = c^2
a^2 + 4^2 = 8^2
a^2 + 16 = 64
a^2 = 64 - 16
a^2 = 48
a^2 = 16 * 3
sqrt(a^2) = sqrt(16*3)
a = 4 * sqrt(3)
That's the height
Trapezoid
b1 = 7
b2 = 7 + 4 = 11
h = 4*sqrt(3)
Area = (b1 + b2)*h / 2
Area = (7 + 11)* 4*sqrt(3)/2
Area = 18 * 2 sqrt(3)
Area = 36* sqrt(3)
