A square has a vertex at (2,3). Name three other possible vertices of the square.
The three other possible vertices of the square are; (-3, 3), (-3, -2) and (2, -2)
What are the vertices of the square?
We are given the vertex of the square as (2, 3).
Now, it is well known that the sides of a square are equal.
This means that there must be another vertex that will have 3 as its' y-coordinate. Similarly, there will be a different coordinate that will have its' x-coordinate as 2.
Similarly, another 2 points will be reflected over the y-axis to get a negative of the previous two x-values. This also applies to the y-values. Thus, when we combine all these together, we will have the coordinates as; (2, 3), (-3, 3), (-3, -2) and (2, -2)

On average, U.S women live more than men in 151,400,000 seconds.
Average:
Average is the ratio of the total value divided by the number of observation used.
Given,
In 2008, the centers for disease control and prevention reported the average human life span in the united states as 76.8 years for men and 81.6 years for women.
Here we need to calculate how much longer, on average, u.s. women live than men in seconds.
Here we know that,
Average life span for men = 76.8 years
Average life span for women = 81.6 years.
So, the women lived
=> 81.6 - 76.8
=> 4.8 years.
So, the average women lived 4.8 years more than the man.
Now we have to convert it into seconds,
We know that,
1 year = 31,536,000 seconds
So,
=> 4.8 x 31,536,000 seconds
=> 151,400,000 seconds.

2. The equation x² + px + q = 0, where p and q are constants, has roots -3 and 5.
(i) Find the values of p and q.
(ii) Using these values of p and q, find the value of the constant r for which the equation
x² + px + q + r = 0 has equal roots.
[3]
The result are-
p = -2 and q = -15.constant r = 64.What is defined as the roots of the quadratic equation?The values of x that correspond to the given quadratic equation ax² + bx + c = 0 are known as its roots.
They are, in other words, the values of the variable (x) that satisfy the equation. The roots of such a quadratic function are indeed the x-coordinates of the function's x-intercepts.The discriminant value indicates how often roots f(x) has: - The quadratic function does have two distinct real roots if b² - 4ac > 0. The quadratic function contains a single repeated real root if b² - 4ac = 0. If b² - 4ac = 0, the quadratic function has really no true roots.For, the given expression;
x² + px + q = 0. ....... (equation 1)
where p and q are constants, has roots -3 and 5.
Part 1: solve for p and q.
Put x = -3 in equation 1.
p(-3) = (-3)² + p(-3) + q = 0
9 - 3p + q = 0 .........(equation 2)
Now, put x = 5 in equation 1.
p(5) = (5)² + p(5) + q = 0
25 + 5p + q = 0 ..........(equation 2)
Solve equation 2 and 3 by elimination method.
p = -2 and q = -15.
Part 2: Estimate the constant r.
The equation is; x² + px + q + r = 0.
Substitute the values of p = -2 and q = -15.
x² + (-2)x + (-15) + r = 0.
As, the equation given real equal roots; then,
discriminant value: b² - 4ac = 0.
Substitute the values;
(-2)² - 4×1×(-15 + r) = 0
On simplification;
4 + 60 - r = 0
r = 64.
Therefore, the value of the constant r is estimated as 64.

-5(7x-9)-6=144 what is the answer.
Answer: x= -3
Step-by-step explanation:
Answer:
x=-3
Step-by-step explanation:
First you must start by multiplying the parentheses by -5. Once you do that, your equation comes out to -35x+45-6=144. Then you must combine like terms which comes out to -35x+39=144. After that you must get x by itself, so to do that subtract 39 from 144 which comes out to 105. Then you must do the opposite of multiplication and divide 105 by -35 which comes out to x=-3.

bills of each type did he deposit?
Mr. Price deposited a $10 bill for $50, a $5 bill for $75, and a $1 bill for $45.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
We have been given that the number of $5 bills was 3 times the number of $10 bills
Let the number of $10 bills would be x
As per the given condition,
$10 = x
$5 = 3x
$1 = 3x+30
Since he deposited $170 in his bank.
So 10x + 5(3x) + 1(3x+30) = 170
⇒ 25x+3x+30=170
⇒ 28x=140
⇒ x = 5
Therefore, $10 for $50
So 3x = 15, $5 for $75
So 3x+30 = 45, $1 for $45
Hence, he deposited a $10 bill for $50, a $5 bill for $75, and a $1 bill for $45.
