Use the given information to find the exact value of each of the following.
a. sin 2theta =
b. cos 2theta =
c. tan 2theta =
cot theta = 11, theta lies in quadrant III
a. sin 2theta =
Answer:
Step-by-step explanation:
cot θ=11
tan θ=1/11
[tex]\sin ~2\theta=\frac{2 \tan ~\theta}{1+\tan^2 \theta} =\frac{2*\frac{1}{11} }{1+(\frac{1}{11} )^2}=\frac{22 }{122} \\\\cos~2 \theta=\frac{1-tan^2 \theta}{1+tan^2\theta} =\frac{1-(\frac{1}{11})^2 }{1+(\frac{1}{11} )^2} =\frac{120}{122} =\frac{60}{61} \\tan 2 \theta=\frac{2 tan\theta}{1-tan^2 \theta} =\frac{2*(\frac{1}{11 } )}{1-(\frac{1}{11} )^2} =\frac{2*11}{120} =\frac{11}{60}[/tex]

Help pls!! Find the value of DB and AE
Answer:
B
Step-by-step explanation:
x=2
3x + 10
3(2) + 10
6+10
16
Db=16
16(x)
16(2)
32=AE
Db=16, 32=AE which is B
plz brainliest
Answer:
16, 32
Step-by-step explanation:
BD is midsegment of the ΔACE ⇒ 16x = 2(3x + 10)
16x - 6x = 20 ⇒ x = 2
BD = 3(2) + 10 = 16 units
AE = 16(2) = 32 units

True or False: If there are multiple operations inside a parentheses, you do not need to complete these in the order of PEMDAS.
Answer:
False
Step-by-step explanation:
I would say false. The operations inside should always go by PEMDAS unless instructed otherwise
Answer:
FALSE
Step-by-step explanation:
Within a set of parentheses, the order of operations should be followed. This is because you will get the wrong answer if you don't.

Mina created a miniature rocket launcher, and the graph shows the height of one of her
rockets relative to the ground over time, where the rocket's height (y) is measured in meters
and time (x) is measured in seconds. *
(2 points)
The Vertex represents
the maximum height of the rocket
the minimum height of the rocket
the moment before the rocket is launched
Answer:
Work individually or in teams of two to construct and launch paper rockets using a teacher-built PVC-pipe launcher.
Following the flight of their rocket, calculate the altitude their rocket achieved.
Based on the flight performance of their rockets, analyze their rocket designs, modify or rebuild them, launch again, and calculate the altitude achieved to determine if their changes affected the performance of the rocket.
Conclude the activity by writing a post-flight mission report.

Which equation is equivalent to the given equation? If anyone can help it means a lot
Answer:
x^2 + 16x + 60 = 0
Step-by-step explanation:
Add 16x to both sides of the given equation. We get x^2 + 16x + 60 = 0.
How do I solve this using long division?
Answer:
x + 5
Explanation:
x^2 + 3x − 10 /x−2
= x^2 + 3x − 10 /x − 2
= (x−2)(x+5) /x−2
= x + 5
15 In rectangle PRST, ST and RT are extended as shown in the diagram below. The measure
of ZPTR is x° and the measure of ZRTS is (2x – 57).
P
R
X
U
(2x - 57)
V
Find the measure of ZUTV.
Find the measure of ZSTV.
Answer:
Z PTS = 90°
or, Z PTS = Z PTR + Z PTS
or, 90° = x° + ( 2x - 57 )°
or, 3x° = 90° + 57°
or, 3x° = 147°
or x° = 49°
ans: Z PTR = Z UTV = 49°
Z STU = 180°
or, Z UTV + Z STV = 180°
or, 49° + Z STV = 180 °
or, Z STV = 180° - 49°
= 131°
ans : Z STV = 131°

7(2x+3)=3(4x+6)+2x+3
Answer:
[tex]7(2x + 3) = 3(4x + 6) + 2x + 3 \\ 14x + 21 = 12x + 18 + 2x + 3 \\ 14x - 14x = 21 - 21 \\ 0 = 0[/tex]
A plot of land is in the shape of a triangle. Two of the angles measure 48 degrees and 74 degrees. The length of the side between them is 90 m.
a) calculate the perimeter of the plot, to the nearest meter.
b) calculate the area of the plot, to the nearest square meter.
Answer:
Perimeter = 271 meters
Step-by-step explanation:
third angle measure would have to be 180 - 122 = 58 degrees
you can use the law of sines:
sin 58° = sin 74°
90 b
.85 = .96
90 b
cross-multiply: .85b = 86.4
b = 102
now do again to find third side:
sin 58° = sin 48°
90 c
.85 = .74
90 c
.85c = 67
c = 79
now you know all 3 sides so add them to get perimeter (79+102+90) = 271

Answer:
(c) 16πx^6y^10
Step-by-step explanation:
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
__
Putting the expression for r in the formula, you have ...
A = πr^2
A = π(4x^3y^5)^2 . . . . . substitute for r
A = π(4^2)(x^(3·2))(y^(5·2)) = 16πx^6y^10

Find the values of x and y.
Answer:
x=30° y=5
Step-by-step explanation:
All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.
so
8y=40
y=40/8
y=5
Since it's an equilateral triangle. All angles are equal And each angle has dimensions
=180°/3=60°
The angle of the straight line = 180°
so The obtuse angle of the lower isosceles triangle is 180°-60°=120°
The angles at the base of the isosceles triangle are equal
so 2x° = 180°-120°
2x°=60°
x°=60°/2
x°=30°
