1. Slope of segment BC
2. Slope of segment AD
3. Length of segment BC
4. Length of segment AD
5. ABCD is a ________
Answer:
Step-by-step explanation:
1 and 2.
slope is m = ( y2-y1) / (x2-x1)
slope of BC = 5-3 /6-1 = 2/5
slope of AD = 1 +1 / 7-2 = 2/5
3 and 4
use the distance formula d= √(x2-x1)² +(y2-y1)²
BC = √( 6-1)²+(5-3)² = √5²+2²= √29
AD = √(7-2)²+(1+1)² = √5²+2² = √29
5.
since BC and AD have the same slope then they are parallel
since BC and AD are same length the segments are ≅
so ABCD is a rectangle

is the square root of 9/31 rational
Answer:
NO
Step-by-step explanation:
no, 9/31 is not an irrational number. ... So we have shown that the square root of any non-square cannot be rational; hence, it is irrational.
The square root of 9/31 rational is not a rational number.
We have given that 9/31.
We have to determine is the square root of 9/31 rational
What is the square root of arational numbers?A rational number is a number that can be expressed as the quotient of two integers, with the denominator not equal to zero.
9/31 is not an irrational number.
So we have shown that the square root of any non-square cannot be rational.
hence, it is irrational.
Therefore it is not a rational number.

The linear function f(x) = 4/5x - 9
Given,
f(-20) = -25
Slope, m = 4/5
We have to find the linear function f(x)
We know the slope-intercept form, y = mx + b
Here,
f(-20) = -25
x = -20 and y = -25
slope, m = 4/5
So, lets solve for b.
y = mx + b
-25 = 4/5 (-20) + b
-25 = 4 × (-4) + b
-25 = -16 + b
Add 16 to both sides
16 - 25 = -16 + 16 + b
We get,
-9 = b
Now, find f(x)
f(x) = 4/5x - 9
That is, the linear function f(x) = 4/5x - 9

Answer:
answer is 14 and it is a example of derivative
Step-by-step explanation:
The weekly revenue for a product is given by R(x) = 324x - 0.0495x?, and the weekly cost is C(x) = 8000 + 162x - 0.099x2 + 0.00003x”, where x is the number of units

(a) How many units will give the maximum profit?
(b) What is the maximum possible profit?
(a) The number of units that will give the maximum profit is
(Round to the nearest whole number as needed.)
Answer:
(a) The number of units that will give the maximum profit is 2,000 units.
(b) The maximum possible profit is $274,000.
Step-by-step explanation:
(a) How many units will give the maximum profit?
From the attached photo in the question, we are given;
R(x) = 324x - 0.0495x^2 ………………....................................……….. (1)
C(x) = 8000 + 162x - 0.099x^2 + 0.00003x^3 …………………….. (2)
In economics, profit function, P(x), is obtained as follows:
P(x) = R(x) - C(x) ………………………. (3)
Substituting the equations (1) and (2) for R(x) and C(x) respectively into equation (3) and then simplify, we have:
P = 324x - 0.0495x^2 - (8000 + 162x - 0.099x^2 + 0.00003x^3)
P = 324x - 0.0495x^2 - 8000 - 162x + 0.099x^2 - 0.00003x^3
P = -8000 + 162x + 0.0495x^2 - 0.00003x^3 ………………….. (4)
Taking a derivative of equation (4) with respect to x and equating to 0, we have:
162 + 0.099x - 0.00009x^2 = 0 .................... (5)
Using the almighty formula as follows:
x = (-b +/- (b^2 - 4ac)^0.5) / 2a ………………. (6)
Where, from equation (5);
a = - 0.00009
b = 0.099
c = 162
Substituting the values into equation (6), we have:
x = (-0.099 +/- (0.099^2 - (4 * (- 0.00009) * 162))^0.5) / (2 * - 0.00009)
x = (-0.099 +/- 0.261) / -0.00018
x = (-0.099 + 0.261) / -0.00018, or x = (-0.099 - 0.261) / -0.00018
x = -900, or x = 2000
Since negative number does not have economic value in economics, the number of units that will give the maximum profit is therefore 2,000 units.
(b) What is the maximum possible profit?
From part a, x = 2000
Substituting x = 2000 into equation (4) and then solve, we have:
P(x) = -8000 + (162 * 2000) + (0.0495 * 2000^2) - (0.00003 * 2000^3)
P(x) = 274,000
Therefore, the maximum possible profit is $274,000.

X-4y=-12 and 5x=20y+60
How do you solve this
Answer:
You must turn the variables, or the "x" into a number to make the numbers on the left equal the numbers on the right.
Step-by-step explanation:
In order to solve these problems, you must replace the variable with a number to have the equation on the left equal what is on the right.
Equation 1:
x - 4y = -12 <----- This is the original problem.
-8 - 4y = -12 <----- Replace the variable.
-12y = -12 <----- This is a true statement.
Equation 2:
5x=20y+60 <----- This is the original problem.
5(16) =20y+60 <----- Replace the variable/Do the addition.
80 = 80y <------ This is a true statement.
Hope this helps! :D

The pressure needed to pump water up to the restaurant on the top floor is 4018000 N/m².
What is pressure?Pressure can be defined as the ratio of force to area of an object.
To calculate the pressure needed, we use the formula below.
Formula:
P = Dgh............... Equation 1Where:
P = Pressure D = Density of waterg = Acceleration due to gravityh = Height.From the question,
Given:
h = 410 mD = 1000 kg/m³g = 9.8 m/s²Substitute these values into equation 1
P = 410×1000×9.8P = 4018000 N/m²Hence, the pressure needed to pump water up to the restaurant on the top floor is 4018000 N/m².

How are the ordered pair (4,9) and (4,-9) similar, and how are they different?
Answer:
Both of the points are in the same x-axis (which is 4). However, they are different because one of them is shifted 9 units up and the other one is shifted 9 units down (their y-axis are different). Their quadrants are also different since (4,9) is at the first quadrant, while (4,-9) is at the fourth quadrant.
