Find the approximate perimeter of the isosceles triangleAOPD. Round your answer to the whole number.
The perimeter of the given triangle is the sum of the following segments:
Perimeter = PD + DO + OP
based on the given graph, you have that the coordinates of the points PDO are:
P: (1,-6)
D: (4,3)
O: (7,-6)
use the following formula for the distance in between two points:
d = √((x2 - x1)²+(y2 -y1)²)
where (x1,y1) and (x2,y2) are two points on the cordinate system.
For segement PD you have:
PD = √((1-4)²+(-6-3)²) = √(100) = 10
For segemtn DO:
DO = √((4-7)²+(-6-3)²) = √(100) = 10
For segment OP:
OP = √((1-7)²+(-6+6)²) = √36 = 6
then, the perimeter of the triangle is:
perimeter = 10 + 10 + 6 = 26

Given,
The expression; 1/4 (3x - 7) + 3/4x
We have to simplify this expression;
Simplification of expressions;
To simplify a phrase, create an equivalent expression without any terms that are identical. The expression will then be rewritten using the fewest terms feasible.
Then,
1/4 (3x - 7) + 3/4x
= 1/4 × 3x - 1/4 × 7 + 3/4x
= 3/4x - 7/4x + 3/4x
= 6x/4 - 7/4
= 3x/2 - 7/4
= 1 1/2x - 1 3/4

What is ascending order?
Suppose there is a series of numbers. The numbers will be in ascending order if the numbers are arranged from their least value to their greatest value.
The sorting of numbers in ascending order plays a very important role in statistics for calculation of median, quartiles, decile and percentile.
Here,
4.79 = 4.79
[tex]4\frac{19}{28} = 4 + \frac{19}{28} = 4.68\\[/tex]

Write an exponential expression equivalent to 8^3 that has a base of 2.
The exponential expression equivalent to 8^3 that has a base of 2 is 2^9.
What is exponential expression?
Powers can simply be expressed in concise form using exponential expressions. The exponent shows how many times the base has been multiplied.
Applying the laws of indices,
The expression 8^3 can be written as,
8 x 8 x 8 = (2^3) x (2^3) x (2^3)
= 2^(3+3+3) ...{If a^m x a^n then a^(m+n) }
8 x 8 x 8 = 2^9

Given
relation = {(9,1), (0,1), (9,-3), (-4,12)}
Find
Is this a function?
Explanation
A relation is a function only if it relates each element in its domain to only one element in the range.
here , domain 9 has two range value 1 and -3
so it is not a function
Final Answer
Hence , it is false
Answer:
False
Step-by-step explanation:
Definition:
Function is a set of coordinate points where each coordinate points do not have same domains (x-values). If we express mathematically, we can do as [tex]\displaystyle{f=\left \{(x_0,y_0),(x_1,y_1),(x_2,y_2),...,(x_n,y_n)\}\right}[/tex] where [tex]\displaystyle{x_0\neq x_1 \neq x_2\neq \dots \neq x_n}[/tex]Function is also considered to be a relation but not all relations can be functions.
As accorded to the relation, it turns out that there are two same domains (x-values) which is 9 from (9,1) and (9,-3). Therefore, this relation doesn’t satisfy the definition of function so it’s not a function.

The list price of an air conditioner is $ 1260. The store offers an off season discount of 16% on it. Find its selling price.
Answer: $1058.40
Step-by-step explanation:
16% of 1260
10%=126
5%=63
1%=12.6
10% divide by 10
5% divide by 10 then divide by 2

When an integer is subtracted from 8 times the next consecutive odd integer, the difference is -33. Find the value of the greater integer.
The two consecutive odd integers are -7 and -5, then the greater integer is -5.
How to find the value of the largest integer?Let's say that the smaller integer is x and the larger one is y.
Such that if both of these are odd and consecutive, then y = 2 + x.
We can now write:
8*y - x = -33
Replacing y by x + 2 we get:
8*(x + 2) - x = -33
8x + 16 - x = -33
7x = -33 - 16 = -49
x = -49/7 = -7

Given, an integer is subtracted from 8 times the next consecutive odd integer, the difference is -33.
Assuming the first odd integer to be 'n'.
So, the next consecutive odd integers are (n + 2), (n + 4)...
∴ 8(n + 2) - n = - 33.
8n + 16 - n = - 33.
7n = - 33 - 16.

What is the linear equation for the line graphed below?
Answer:
y = -3x + 7
Step-by-step explanation:
Hello!
Slope-Intercept Form: y = mx + b
m = slopeb = y-interceptThe y-intercept of the graph, or the point where the graph intersects the y-axis, is 7.
We can find the slope by finding the Rise/Run.
The graph rises negatively by 3 units as it runs positively by 1 unit, so the slope is -3/1 or -3.
Given the slope and y-intercept, the equation of the line is y = -3x + 7.
