Answer:
8
Step-by-step explanation:
Measure of one interior angle of a regular polygon of n sides:
(n - 2)180/n
Measure of one exterior angle of a regular polygon if n sides:
360/n
"the interior angle is thrice the exterior angle"
(n - 2)180/n = 3 * 360/n
(n - 2)180 = 3 * 360
n - 2 = 3 * 2
n = 8
The number of sides is 8.
The table shows the outputs y, for different inputs ,x
Input x: 3,7,11,15
Output y: 4,6,8,10
Part A: Do the data in this table represent a function? Justify your answer.
Part B: Compare the data in the table with the relation f(x) = 5x-21. Which relation has a greater value when x=11
Part C: Using the relation in part b, what is the value of x if f(x) =99
Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.
(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.
Part B: All we have to do is plug in 11 for x in the function given to find the answer:
In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.
Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:
What is the answer for 4(2p-8)-6p=20+4(p+6)
Hello! :)
[tex]\large\boxed{p = -38}[/tex]
4(2p - 8) - 6p = 20 + 4(p + 6)
Distribute the coefficients outside of the parenthesis:
4(2p) + 4(-8) - 6p = 20 + 4(p) + 4(6)
8p - 32 - 6p = 20 + 4p + 24
Combine like terms:
2p - 32 = 44 + 4p
Subtract 2p from both sides:
-32 = 44 + 2p
Subtract 44 from both sides:
-76 = 2p
Divide both sides by 2:
p = -38.
Answer p = -4
6p + 2(4 + -2p) = 3(p + 4)
6p + (4 * 2 + -2p * 2) = 3(p + 4)
6p + (8 + -4p) = 3(p + 4)
8 + 6p + -4p = 3(p + 4)
8 + 2p = 3(p + 4)
8 + 2p = 3(4 + p)
8 + 2p = (4 * 3 + p * 3)
8 + 2p = (12 + 3p)
8 + 2p = 12 + 3p
8 + 2p + -3p = 12 + 3p + -3p
8 + -1p = 12 + 3p + -3p
8 + -1p = 12 + 0
8 + -1p = 12
8 + -8 + -1p = 12
0 + -1p = 12 + -8
-1p = 12 + -8
-1p = 4
p = -4

What is the slope and y intercept for 14X - 7Y = 28
Answer:
y = 2x - 4 (the slope is 2 or 2/1 and the y-intercept is -4)
Step-by-step explanation:
Subtract 14x from both sides of the equation.
This should get you -7y = 28 - 14x.
Then you need to divide by -7 on both sides.
y = -4 + 2x is the result
which you can switch around if you like and get y = 2x - 4

Why is it essential to know how to solve Exponential equations in order to solve Logarithmic equations? (Make sure to fully explain).
Answer:
Because you need it for your later life and for your GCSES and if you dont want to fail then you will need it.
Step-by-step explanation:
Given an exponential equation in which a common base cannot be found, solve for the unknown. Apply the logarithm of both sides of the equation. If one of the terms in the equation has base 10, use the common logarithm. If none of the terms in the equation has base 10, use the natural logarithm.

In a circle with radius 2, an angle measuring pi/3 radians intercepts an arc. Find the
length of the arc in simplest form.
Answer:
2pi/3
Step-by-step explanation:
Using the formula s = r(theta), where s is arc length, r is radius, and theta is the central angle,
s = 2(pi/3)
s = 2pi/3

six Notebooks cost 720 find the cost of 44 note books
Explanation:
720/6 = 120
44 x 120 = 5280
Answer:
$5280
Hope this helps!!!!!
Step-by-step explanation:
Cost of 6 notebooks = 720
Then, cost of 1 notebook = 720/6
Therefore, cost of 44 notebooks = 720/6 x 44
= 120 x 44
= 5,280
Therefore, the cost of 44 notebooks will be 5,280

Learning Task 4 : Do the following in your notebook.
A. Find the equation of the line given the graph.
Answer:
Question 3: y =x+2
Step-by-step explanation:
to find the equation use y=mx+c where m is the gradient/slope and c is the y intercept. In example 3, the y intercept is 2 so thats why the equation ends in +2, and the slope which is calculated by rise over run, is 2 over 2, or 1 so x doesnt need a coefficient.
