Find the image of G when A IMG is rotated 180 around the origin.
O (2,4)
O (-2,-4)
O (-1.3)
O (2.-4)
The image of G when A IMG is rotated 180 around the origin is (-2,-4).
To rotate a figure 180 degrees around the origin, we reverse the signs of both the x-coordinate and the y-coordinate. In the image, the point G has coordinates (2,4). Reversing the signs of these coordinates gives us (-2,-4).
Rotate the figure 180 degrees around the origin. This means that we imagine the figure being flipped over the origin.
Reverse the signs of both the x-coordinate and the y-coordinate of the point G. This is because when we rotate a figure 180 degrees around the origin, the signs of both the x-coordinate and the y-coordinate are reversed.
The new coordinates of G are the coordinates of the point that is the result of rotating the figure 180 degrees around the origin and reversing the signs of the coordinates of point G. In this case, the new coordinates of G are (-2,-4).

Answer:
x = 6
Step-by-step explanation:
Line segment SU is a bisector of angle <TSV which means it divided the angle into two equal parts:
The measure of <TSV = 62 in this case the measure of <VSU = 62/2 = 31
we can write the following equation to find the value of x
5x + 1 = 31 subtract 1 from both sides
5x = 30 divide both sides by 5

6) A basket contains 5 yellow, 3 blue and 2 white balls. If a ball is drawn randomly from the basket, find the probability of not getting a blue ball.
Answer: 70%
Step-by-step explanation:
A basket contains:
5 yellow balls
3 blue balls
2 white balls
What would be the probability of randomly picking a ball and the ball not being blue?
So, we can find the probability of picking up a blue ball. Let's do that first.
To calculate the probability of getting a blue ball, we need to divide the number of blue balls by the number of possible balls.
The number of blue balls = 3
The total number of balls = 2 + 3 + 5 = 10 balls
3 blue balls divided by 10 balls = 0.3.
If you multiply 0.3 by 100%, it will give you a probability of finding a blue ball equal to 30%
Now, we just need to find the probability of NOT finding a blue ball. Because we have 30% of finding a blue ball, we just need to subtract 30% from 100%.
100 - 30$ = 70%
The probability of not getting a blue ball is equal to 70%.

Which equation is represented by the model? 3x2 – 4x – 1 = (3x 1)(x – 1) 3x2 – 2x – 1 = (3x – 1)(x 1) 3x2 – 4x 1 = (3x – 1)(x – 1) 3x2 – 2x 1 = (3x – 1)(x – 1)
The equation represented by the model is 3x²-4x+1=(3x-1)(x-1).
Given model represents a polynomial of the form ax²+bx and model is in figure.
Consider the given table.
The first row in the table represents first term of the polynomial.
In first row first three terms are variables and last term are constant.
Write all the terms of the first row in the form of sum.
+x+x+x-1=3x-1
The first column in the table represents second term of the polynomial.
In first column first term are variable and last term are constant.
Write all the terms of the first column in the form of sum.
+x-1=x-1
The product of first term of polynomial (3x-1) and second term of polynomial (x-1) is equal to the sum of all remaining terms in this table.
+x²+x²+x²-x-x-x-x+1=3x²-4x+1.
We can also check this by multiplying (3x-1) and (x-1) as
(3x-1)(x-1)=3x(x-1)-1(x-1)
(3x-1)(x-1)=3x(x)-3x(1)-1(x)+1(1)
(3x-1)(x-1)=3x²-3x-x+1
(3x-1)(x-1)=3x²-4x+1
Hence, the equation represented by the given model in the form of polynomial ax²+bx is (3x-1)(x-1)=3x²-4x+1.

How do you represent a table with linear functions
A table can be represented with a linear function equation as y = mx + b, where m is the slope and b is the y-intercept.
How to Represent a Table with Linear Function?Assuming we have a table of values as shown in the image attached below, to write an equation of linear function for the table, do the following:
Pick two pairs of values, say, (1, 5) and (2, 25) and find the slope (m):
Slope (m) = change in y / change in x = (25 - 5)/(2 - 1)
Slope (m) = 20
Find the y-intercept (b) by substituting (x, y) = (1, 5) and m = 20 into y = mx + b:
5 = 20(1) + b
5 = 20 + b
5 - 20 = b
-15 = b
b = -15

The features of the function g(x) = 4log(x) + 4 are
(b) range (-∞, ∞)(d) x-intercept (0.1, 0)(e) Vertical asymptote, x = 0How to determine the features of g(x)?The function is given as;
g(x) = 4log(x) + 4
The intercept
A logarithmic function has no y-intercept.
Set g(x) to 0, to determine the x-intercept
4log(x) + 4 = 0
Divide through by 4
log(x) + 1 = 0
This gives
log(x) = -1
Take the inverse of both sides
x = 10^-1
Evaluate
x = 0.1
The x-intercept is (0.1, 0)
The vertical asymptote
Recall that:
A logarithmic function has no y-intercept.
This is so because it is undefined at x = 0
So, the vertical asymptote is x = 0
The domain and the range
A logarithmic function cannot take a negative input or 0 input
So, the domain is x > 0
However, the range is all set of real numbers i.e (-∞, ∞)
Hence, the features of g(x) are (b), (d) and (e)

Answered by : ❝ AǫᴜᴀWɪᴢ ❞
The value of ED is 5 units, which is determined by using the concept of midpoint.
The figure given below shows a line segment FD, where the length of line segment FD refers to the distance between its endpoints, F and D.
Given that E is the midpoint of FD.
FE = 5 units
FD = 10 units
Since M is the midpoint of FD, So FE = ED
⇒ FD = FE + ED
Substitute the values of FE = 5 and FD = 10, in the above equation,
⇒10 = 5 +ED
⇒ ED = 10 - 5
⇒ ED = 5
Therefore, the value of ED is 5 units.

Step 2: Multiply 40 by 3
40 · 3 = 120
Answer: 3/5 of 200 = 120
Tip: When finding a fraction of a whole, divided the whole by the denominator, then multiply the quotient you got by dividing the whole by the denominator by the numerator

A and b are monomials where a = 125 and b = 27p12. what is the factored form of a – b? (5 – 3p4)(25 15p4 9p8) (25 – 3p4)(5 15p3 9p3) (25 – 3p4)(5 15p4 3p8) (5 – 3p4)(25 15p3 3p4)
The correct option is (A). The factored form of a-b is (5-3p⁴)(25+15p⁴+9p⁸).
Given that A and B are monomials where a = 125 and b = 27p¹².
Monomial expressions include only one non-zero term. Numbers, variables, or multiples of numbers and variables are all examples of monomials.
Firstly, substitute a=125 and b = 27p¹² into a-b, we get
a-b=125-27p¹² ......(1)
As we know, 125=(5)³, 27p¹²=(3p⁴)
So, equation (1) can be rewritten as
a-b=(5)³-(3p⁴)
Now, apply a³-b³=(a-b)(a²+ab+b²).
a³-b³=(5-3p⁴)(5²+5(3p⁴)+(3p⁴)²)
Further, Simplify using exponent rule with the same exponent (ab)ⁿ=aⁿbⁿ.
a³-b³=(5-3p⁴)(5²+5×3p⁴+3²×(p⁴)²)
Furthermore, calculate the power, we get
a³-b³=(5-3p⁴)(5²+5×3p⁴+9(p⁴)²)
Then, Simplify using exponent power rule (aˣ)ⁿ=aˣⁿ, we get
a³-b³=(5-3p⁴)(5²+5×3p⁴+9p⁸)
Now, multiply the monomials, we get
a³-b³=(5-3p⁴)(5²+15p⁴+9p⁸)
Further, calculate the power, we get
a³-b³=(5-3p⁴)(25+15p⁴+9p⁸)
Finally, reorder the expressions, we get
a³-b³=(5-3p⁴)(9p⁸+15p⁴+25)
Hence, the factored form of a-b where a and b monomials and a = 125 and b = 27p¹² is (5-3p⁴)(9p⁸+15p⁴+25).
