Answer:
89.8 feet
Step-by-step explanation:
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
We would solve the above question using Sine rule
The formula is given as:
DB/sin D = BC/sin B
93/sin 90 = BC/sin 75
We cross multiply
sin 90 × BC = 93 × sin 75
BC = 93 × sin 75/sin 90
BC = 89.83 feet
Approximately BC = 89.8 feet

Answer:
k+4

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

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.

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)....................

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

An iPod uses a standard 1.7 volt battery. How much resistance is in the circuit if it uses a current of
0.03 amps?
Answer:
R = 56.6 ohms
Step-by-step explanation:
Given that,
The voltage of the battery, V = 1.7 volt
We need to find the resistance in the circuit if it uses a current of 0.03 A.
Let the resistance be R. It can be solved using Ohms law as follows :
V = IR
[tex]R=\dfrac{V}{I}\\\\R=\dfrac{1.7}{0.03}\\R=56.6\ \Omega[/tex]
So, the resistance in the circuit is 56.6 ohms.
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°

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!

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.
