Ten points labeled A, B, C, D, E, F, G, H, I, J are arranged in a plane in such a way that no three lie on the same straight line.
a. How many straight lines are determined by the ten points?
b. How many of these straight lines do not pass through point A?
c. How many triangles have three of the ten points as vertices?
d. How many of these triangles do not have A as a vertex?
Therefore, there are 45 straight lines determined by the ten points. Therefore, there are 36 straight lines that do not pass through point A. Therefore, there are 120 triangles with three of the ten points as vertices. Therefore, there are 84 triangles that do not have A as a vertex.
a. To determine the number of straight lines determined by ten points, we can use the formula for combinations. The number of ways to choose two points out of ten is given by C(10, 2), which can be calculated as:
C(10, 2) = 10! / (2! * (10-2)!)
= 10! / (2! * 8!)
= (10 * 9) / (2 * 1)
= 45
b. To find the number of straight lines that do not pass through point A, we consider that any straight line passing through A would include one of the remaining nine points. Hence, we need to find the number of straight lines determined by the remaining nine points.
Using the same formula as before, the number of ways to choose two points out of nine is given by C(9, 2), which can be calculated as:
C(9, 2) = 9! / (2! * (9-2)!)
= 9! / (2! * 7!)
= (9 * 8) / (2 * 1)
= 36
c. To determine the number of triangles with three of the ten points as vertices, we can use the formula for combinations. The number of ways to choose three points out of ten is given by C(10, 3), which can be calculated as:
C(10, 3) = 10! / (3! * (10-3)!)
= 10! / (3! * 7!)
= (10 * 9 * 8) / (3 * 2 * 1)
= 120
d. To find the number of triangles that do not have A as a vertex, we consider that any such triangle would have its vertices chosen from the remaining nine points.
Using the same formula, the number of ways to choose three points out of nine is given by C(9, 3), which can be calculated as:
C(9, 3) = 9! / (3! * (9-3)!)
= 9! / (3! * 6!)
= (9 * 8 * 7) / (3 * 2 * 1)

The City of Killeen utilities charges for water usage per gallon on a monthly basis as listed below.
Up to 500 gallons ($0.15/gallon)
More than 500 gallons - 1000 gallons ($0.33/gallon)
How much will Mrs Lapid pay if she uses 795 gallons in a particular month?
Answer:
$262.35
Step-by-step explanation:
From the above question we are given the cost for a given range of gallons
Mrs Lapis uses 795 gallons, hence this falls into the range of:
More than 500 gallons - 1000 gallons ($0.33/gallon)
Hence:
1 gallon = $0.33
795 gallons = $x
Cross Multiply
1 gallon × $x = $0.33 × 795 gallons
$x = 795 × $0.33
x =$ 262.35
Therefore, Mrs Lapis would pay $262.35 every month

Step-by-step explanation:
g+6=3=31
3+4=31
g+3-3=31-3
g=31-3
g=28
Answer:
28
Step-by-step explanation:
We want to isolate G so that it's by itself on one side of the equals sign. In order to do this, we need to get rid of the 6 and the 3.The first thing we do is add the -3 to both sides. Adding a negative number will eliminate it, as -3 + 3 would equal 0. We need to do this to both sides since that's the rules of algebra.Once we add the 3, we have G + 6 = 34.Now we subtract the 6 from both sides.We end up with G = 28.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

A growing community increases its consumption of electricity per yr.
(a) If the community uses 1.1 billion units of electricity now, how much will it use from now? Round to the nearest tenth.
(b) Find the number of years (to the nearest year) it will take for the consumption to double.
(a) The community will use approximately 1.21449 billion units of electricity 5 years from now.
(b) It will take approximately 35 years for the consumption to double.
(a) To calculate the electricity consumption of the community 5 years from now, we need to apply the annual growth rate of 2% to the current consumption of 1.1 billion units.
The formula to calculate the future value with a constant growth rate is:
Future Value = Present Value * (1 + Growth Rate/100)^Number of Years
Let's calculate the future value:
Future Value = 1.1 billion * (1 + 2/100)⁵
Future Value = 1.1 billion * (1.02)⁵
Future Value ≈ 1.1 billion * 1.10408
Future Value ≈ 1.21449 billion
Therefore, the community will use approximately 1.21449 billion units of electricity 5 years from now.
(b) To find the number of years it will take for the consumption to double, we need to determine the time it takes for the initial consumption to increase by 100% or multiply by 2.
Let's set up the equation:
Future Value = Present Value * (1 + Growth Rate/100)^Number of Years
2 * Present Value = Present Value * (1 + 2/100)^Number of Years
Dividing both sides by Present Value:
2 = (1 + 2/100)^Number of Years
Taking the natural logarithm of both sides:
ln(2) = Number of Years * ln(1 + 2/100)
Number of Years = ln(2) / ln(1 + 2/100)
Using a calculator, we can determine the approximate value of Number of Years:
Number of Years ≈ 34.66
Therefore, it will take approximately 34.66 years for the consumption to double. Rounded to the nearest year, it will take about 35 years.

Determine the equation of the tangent plane and normal line of
the curve f(x,y,z)=x2+y2-2xy-x+3y-z-4 at p(2,
-3, 18)
To determine the equation of the tangent plane and normal line of the given curve at the point P(2, -3, 18), we need to find the partial derivatives of the function f(x, y, z) = x^2 + y^2 - 2xy - x + 3y - z - 4.
Taking the partial derivatives with respect to x, y, and z, we have:
fx = 2x - 2y - 1
fy = -2x + 2y + 3
fz = -1
Evaluating these partial derivatives at the point P(2, -3, 18), we find:
fx(2, -3, 18) = 2(2) - 2(-3) - 1 = 9
fy(2, -3, 18) = -2(2) + 2(-3) + 3 = -7
fz(2, -3, 18) = -1
The equation of the tangent plane at P is given by:
9(x - 2) - 7(y + 3) - 1(z - 18) = 0
Simplifying the equation, we get:
9x - 7y - z - 3 = 0
To find the equation of the normal line, we use the direction ratios from the coefficients of x, y, and z in the tangent plane equation. The direction ratios are (9, -7, -1).Therefore, the equation of the normal line passing through P(2, -3, 18) is:
x = 2 + 9t
y = -3 - 7t
z = 18 - t
where t is a parameter representing the distance along the normal line from the point P.

he eardrum is a membrane located in the middle ear that vibrates when sound waves hit it. assume an eardrum has an area of 5.10 ✕ 10−5 m2.
(a) The average sound power incident on an eardrum at the threshold of pain is 5.00 × \(10^(-5)\) W. (b) The energy transferred to the eardrum exposed to this sound for 1.50 min is 4.5 J.
(a) The intensity of a sound wave is defined as the power per unit area. In this case, the intensity at the threshold of pain is given as 1.00 W/\(m^2\) The average sound power incident on the eardrum can be calculated by multiplying the intensity by the area of the eardrum. Therefore, average sound power = intensity × area = 1.00 W/\(m^2\) × 5.00 × \(10^(-5)\) \(m^2\) = 5.00 × \(10^(-5)\) W.
(b) To calculate the energy transferred to the eardrum exposed to the sound for 1.50 min, we need to first determine the total power incident on the eardrum. The power is calculated as the product of intensity and area, which is 1.00 W/\(m^2\) × 5.00 × \(10^(-5)\) \(m^2\) = 5.00 × \(10^(-5)\) W.
Since power is the rate at which energy is transferred, we can calculate the energy transferred over time using the formula: Energy = Power × Time. Substituting the values, we have Energy = 5.00 × \(10^(-5)\) W × (1.50 min × 60 s/min) = 4.5 J.
