Answer:
x = 18
By Pythagoras Theorem:
[tex] {(x + 7)}^{2} = {(7)}^{2} + {(24)}^{2} \\ \\ \implies \: (x + 7)^{2} = 49 + 576 \\ \\ \implies \: (x + 7)^{2} = 625\\ \\ \implies \: x + 7 = \pm \sqrt{625}\\ \\ \implies \: x + 7 = \pm \: 25\\ \\ \implies \: x + 7 = 25 \: \: or \: \: x + 7 = - 25 \\ \\ \implies \: x = 25 - 7 \: \: or \: \: x = - 25 - 7 \\ \\ \implies \: x = 18 \: \: or \: \: x = - 32 \\ \\ x \: can \: not \: be \: negative \\ \implies \: x \neq \: - 32 \\ \implies \: x = 18[/tex]

(b) What output does the rule give when the input is 3, -4 ? Show your work.
(c) Is the rule a function? Explain why it is or why it is not
Answers
Answer:
(x-3,y+4) is the rule
a. -6, 0 input. This would equal (-6)-3 for x and (0)+4 for y. Answer: -9, 4
b. 3, -4 input. This would equal (3)-4 for x and (-4)+4 for y. Answer: -1, 0
c. The rule is a function because each input only has one output
Answer:
QuestionAlicia is writing the program for a video game. For one part of the game she uses the rule (x, y) → (x - 3,y + 4) to move points on the screen.
(a) What output does the rule give when the input is (-6, 0)?
Show your work.
(b) What output does the rule give when the input is (3, -4)?
Show your work.
(c) Is the rule a function? Explain why it is or why it is not.
Solution(a) Input (-6, 0) → Output (-6 - 3, 0 + 4) = (-9, 4)
(b) Input (3, -4) → Output (3 - 3, -4 + 4) = (0, 0)
(c) The rule is a one-to-one function as each value in the range (y-values) corresponds to exactly one value in the domain (x-values).

Step-by-step explanation:
Transformation Rules
[tex]f(x+a)=f(x) \: \textsf{translated}\:a\:\textsf{units left}[/tex]
[tex]f(x-a)=f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]
Given equation: [tex]y=x^3+6[/tex]
If the graph of the equation is translated 4 units to the right, then we replace [tex]x[/tex] with [tex](x-4)[/tex]:
[tex]\implies y=(x-4)^3+6[/tex]
[tex]\implies y=(x-4)(x-4)(x-4)+6[/tex]
[tex]\implies y=(x-4)(x^2-8x+16)+6[/tex]

Step-by-step explanation:
Same side interior angles of parallel lines cut by a transversal are supplementary, so their measures have a sum of 180°.

show that the derivative of an odd function is even function and viceversal
Answers
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.

Enter the measure of ∠TOM, in degrees. (Enter just the number)
Answers
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 °

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

Answers
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.
