help pls i'm not good at math
Answer: x = 56
Step-by-step explanation:
The two angles 'z' and 124 add up to form a straight line. The angle of a straight line is 180 degrees. Therefore, we can say that:
[tex]z+124=180[/tex]
Subtract 124 on both sides to isolate the angle 'z' to get:
[tex]z=56[/tex]
Answer:
z=56 degrees
Step-by-step explanation:
in total the line will equal 180 so just do 180-124 and you get 56.
show that the derivative of an odd function is even function and viceversal
Step-by-step explanation:
Well, it's hard to generalize this. But I can show you a few examples using the power rule and some derivatives of trig functions. Lets say we have a function:
[tex]f(x) = {x}^{n} [/tex]
Then you should know it's derivative is:
[tex] \frac{df}{dx} = n {x}^{n - 1} [/tex]
For polynomial functions, a subtraction of 1 from the exponent will turn any odd function into an even, and any even function to an odd. An example of this is x^3, which is odd. The derivative is 3x^2, which is even. Another example, this time of a trig function, is sine and cosine. Sine is odd, while cosine is even. The derivative of sine is cosine, and the derivative of cosine is negative sine.
Help I know that I have to move 3x to 4x with will be -3x and then I will subtract it then I will be left with -x and then I'll be with -x -3 what do I do after ?
4x -3 = 3x
Answer:
[tex]\sf \boxed{\bold{x = 3}}[/tex]
Explanation:
4x -3 = 3xsubtract both sides by 4x
4x - 3 -4x = 3x - 4xgroup similar terms
4x - 4x - 3 = -xsimplify
-3 = -xdivide both sides by -1 or cancel out the negatives
x = 3Check:
4(3) -3 = 3(3)12 - 3 = 99 = 9L.H.S = R.H.S Thus x = 3 confirmed
Answer:
x = 3
Step-by-step explanation:
We are trying to move all terms that have x on one side of the equal sign and terms that do not have an x on the other side of equal sign.
terms with x = terms without x
4x -3 = 3x , subtract 3x from both side of the equation
4x -3x -3 = 3x -3x
4x -3x -3 = 0 , add 3 to both sides of the equation
4x -3x -3 + 3 = 0 + 3
4x -3x = 3 , combine like terms
x = 3
Or
We can think we move each term where we want it, yet keep in mind that once we cross the equal sign we change the sign of the term if addition or subtraction are the only operations involved.
4x -3 = 3x , 3x is positive so will become negative on the other side of the equal sign and -3 is negative so will become positive on the other side.
4x -3x = 3
x = 3

The seattle great wheel is an illustration of sectors, arcs, circumference and area of circles
The circumference of the wheelThe diameter is given as:
d = 175 feet
The circumference (C) is calculated as:
C = πd
This gives
C = 3.14 * 175
C = 549.5 feet
Hence, the circumference of the wheel is 549.5 feet
The area of the wheelThis is calculated as:
A = π(d/2)^2
This gives
A = 3.14 * (175/2)^2
A = 24040.625
Hence, the area of the wheel is 24040.625 square feet
The central angle (degrees)This is calculated as:
θ = 360/n
Where n is the number of capsules
So, we have:
θ = 360/42
This gives
θ = 8.57 degrees
Hence, the central angle of the wheel in degrees is 8.57
The central angle (radians)This is calculated as:
Radians = Degrees × π/180
So, we have:
θ = 360/42 * π/180
This gives
θ = π/21 rad
Hence, the central angle of the wheel in radians is π/21 rad
Arc length between two capsulesThis is calculated as:
L = θ * d/2
So, we have:
L = π/21 * 175/2
This gives
L = 175π/42
Hence, the arc length between two capsules is 175π/42
Area of sector between two capsulesThis is calculated as:
A = 0.5 * (d/2)^2 * θ
So, we have:
A = 0.5 * (175/2)^2 * π/21
This gives
A = 168π
Hence, the area of sector between two capsules is 168π

Enter the measure of ∠TOM, in degrees. (Enter just the number)
Answer: 150
Step-by-step explanation:
We know (5x-15)+(2x)=90 degree
so we can solve x = 15
plug in 5(15) - 15 = 60
60 + 90 = 150
Answer:
150
Step-by-step explanation:
m∠TOG = m∠TOP + m∠POM + m∠MOG
m∠TOG = 180°
m∠TOP = 90°
m∠POM = (5x - 15)°
m∠MOG = (2x)°
90 + ( 5x - 15 ) + 2x = 180 ⇒ 5x - 15 + 2x = 90 ⇒ x = 15
m∠TOM = 90° + m∠POM
m∠TOM = 90° + (5×15 - 15)° = 150 °
