(cos^2x-sin^2x)-sin4x+sin^22x=0
Answer:
x=22.5
Step-by-step explanation:
(there's a correction in the question since the I did this one before, so I know)
(cos²x-sin²x)²-sin4x+sin²2x=0
or, cos²2x-sin4x+sin²2x=0
or, 1-sin4x=0
or, sin4x=1
or, 4x=90
or, x=22.5

equivalent expression: 3 + 4(2z - 1)
Answer:
8z - 1
Step-by-step explanation:
Given
3 + 4(2z - 1) ← multiply each term in the parenthesis by 4
= 3 + 8z - 4 ← collect like terms
= 8z - 1
Answer:
-1 + 8z
Step-by-step explanation:
First use the distributive property of multiplication (Just multiply 4 with all numbers in the parenthesis):
3 + 4(2z - 1)
3 + 8z - 4
Group like terms:
3 + 8z - 4
-1 + 8z
The answer is -1 + 8z
Hope this helped.
HELP PLS IM FAILING PYTHAGOREAN THEOREM
Answer: 4.6 km
Step-by-step explanation:

4 + b^2 = 25
b = sqrt 25 - 4
b = sqrt 21 = 4.6 km
Which angles are adjacent to each other?
Angle CHG and Angle HDL
Angle AEB and Angle DEA
Angle CHG and Angle HCE
Angle JCH and Angle CHG
Please make sure it's correct because one person once tried it and got it wrong..lol.
Answer:
B
Step-by-step explanation:
Adjacent angles must have the same vertex, so if the middle letter of the three letters used to name each of the angles in a pair are not the same, the angles cannot be adjacent.
That eliminates choices A, C, and D.
Answer: B
Look in the picture first below. Each pair of angles with the same vertex marked in blue is a pair of adjacent angles. For two angles to be adjacent angles, they must be next to each other, have the same vertex, and one cannot be inside the other.
Now look in the second picture below. Each pair of angles marked in red is not a pair of adjacent angles. Some of them are not next to each other. Others have one angle inside the other.
please tell me what x =?
Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from angle x, we know the opposite side and the adjacent side. Therefore, we should use the tangent function to solve.
tan(x) = 8/10
x = tan^-1(8/10)
x = 38.7 degrees
Hope this helps!
Area of parallelogram!!
Answer:
3.375 cm^2
Step-by-step explanation:
The area of a parallelogram is given by
A = bh where b is the base and h is the height
A = 2.25 * 1.5
A =3.375 cm^2
Area = length x height
Area = 2.25 x 1.5
Area = 3.375 cm^2
Can someone help me out
Answer:
17.6 mi
Step-by-step explanation:
I know you are using Windows 10 OS or something because of the cortana thingie and task bar option, and you can do Windows Key + Shift + S to take a screenshot.
This gives much better quality than a third party device and lets us evade the terrible pixel green line rippley thingies that form. Plus it is more efficient and faster.
Circumference formula is Diameter * Pi.
I assume the 5.6 mi. is the diameter since the line segment is going completely through the circle.
Pi is something of the lines of 3.141592653 blah blah blah and goes on forever, but the point is, we take it to be 3.14 when doing circle stuff so we don't die from old age trying to figure out a question of a 1 x 1 circle.
So 5.6 * 3.14 is 17.584 which is your answer.
It says to round to the nearest tenth though, so you round and get
17.6 since the 5 in 17.584 is the tenths place, the 8 is the hundredths place, the 4 is the thousandths place and so on and so forth.
(The " * " symbol represents multiplication and is in use all the time when going to higher levels of education.)
Given f(x)=3x^3-4x+k and x+2 is a factor of f(x), then what is the value of k?
Answer:
k is 16
Step-by-step explanation:
Factor is ( x+2 ):
[tex]{ \sf{x + 2 = 0}} \\ { \sf{x = - 2}}[/tex]
Root is -2.
[tex]{ \bf{f(x) = 3 {x}^{3} - 4x + k}} \\ { \sf{f( - 2) = 0}} \\ { \sf{3 {( - 2)}^{3} - 4( - 2) + k = 0 }} \\ { \sf{ - 24 + 8 + k = 0}} \\ { \sf{ - 16 + k = 0}} \\ { \sf{k = 16}}[/tex]
Can someone please help me out Its really Important please marking brainliest Answer what you can
Answer:
1.
a rectangular prism is simply a block. it has length, width and height. and similar to the area of a rectangle (length×width) we get as volume length×width×height.
other than that we only need to consider that a volume always has cubic units (like cm³, m³, ft³, ...).
the volume of a cylinder is again ground area times height, when we imagine the cylinder to stand on it circular side.
and the states standard formula (hi, internet !) for the volume of a cylinder is pi×r²×height
so, we have 75×20×14 = 21,000 cm³
and pi×75²×120 = pi×5625×120 = 2,120,575 cm³
so, the cylinder has a much bigger volume.
3.a.
the standard formula for the volume of a pyramid (hi, internet !) is length×width×height/3
the diagram means that it is a square pyramid (the ground area is a square). therefore all sides of the ground area are of equal length. length = width
so, we have 64×64×40/3 = 54631.333... m³
3.b.
as the description says, 5000 people fit in, so, to find how much volume is there available per person, we need to divide the volume by 5000.
54631.333... / 5000 = 10.923 m³
Step-by-step explanation:
and again, you need only to search the formulas on the internet, and then calculate this with the given numbers yourself, and you will be much faster than paying things here and waiting for answers and copy/pasting things.
again, there is practically nothing to explain, just to use the standard formulas and the calculator. what's the problem ?
I will gladly explain to you concepts you have not understood (that is the point of Brainliest). but I and others here are not your personal slaves to do your work for you.
0.741 round to nearest one
Answer:
Step-by-step explanation:
Since round to the nearest one is too vague, i'll give everything this can be rounded too
Rounded to the nearest whole number
0.741 = 1
Rounded to the nearest tenth
0.741 = 0.7
Rounded the the nearest hundreth
0.741 = 0.74

b) (2x - 3)(2x + 4) = 4x^2 + 2x - 12
c) (x + 2)(avg. length of base, x + 6) = x^2 + 8x + 12
d) Is the radius 4x + 12? If so: (4x + 12)(4x + 12) = (16x^2 + 96x + 144) x pi

Solve 4 sinx + 9 cosx=0 for 0°
4 sin(x) + 9 cos(x) = 0
4 sin(x) = -9 cos(x)
tan(x) = -9/4
x = arctan(-9/4) + nπ … … … (in radians)
or
x = arctan(-9/4) + 180n ° … … … (in degrees)
where n is any integer.
I'm guessing you're solving for x over some domain, probably 0° ≤ x < 360°. In that case, you would have two solutions for n = 1 and n = 2 of
x ≈ 113.96° and x ≈ 293.96°

A. 12
B. 14.5
C. 16.6
D. 18.9
Answer:
The mean is C. 16.6
Step-by-step explanation:
the mean is the average, to find the average add all the numbers together and divide by the amount of numbers
4+11+25+1+17+34+11+30=133
133/8 = 16.6

and
Answer:
Step-by-step explanation:
This is a fascinating question. It turns out to be true because of the relationship between a 30 degree angle and a 60 degree angle
The answer is that the product of sin30*sin60 = cos(30)*cos(60). This happens because sin(60) = cos(90-60) = cos(30)
Other angles will do the same thing sin36 * sin54 = cos(54)*cos(36)

1. t — 19 = 2
2. 1 + s = 3
3. 24 = 4c
4. v/5 = 9
(show work)
Answer:
1. t = 21
2. s = 2
3. c = 6
4. v = 45
Step-by-step explanation:
1. t - 19 = 2
*Add 19 to both sides.
t = 21
2. 1 + s = 3
*Subtract 1 from both sides.
s = 2
3. 24 = 4c
*Divide each side by 4.
6 = c
4. v/5 = 9
*Multiply each side by 5.
v = 45
