What is the point-slope form of a line with slope -3 that contains the point
(10, -1)?
Answer:
y - (-1) = -3(x-10)
y+1= -3x+30
y= -3x+30-1
y= -3x+29
for the figure shown below, find the value of the variable and the measure of the angles.
x is
measure angle P
measure angle Q
measure angle R
Answer:
All triangles has a total angle of 180. So x+38+2x+18+x=180
Solve for x: 4x+56=180 so 4x=124, x=31
The demand for tickets to an amusement park is given by p = 70 - 0.2q, where p is the price of a ticket in dollars and q is the number of people attending at that price.
a. What price generates an attendance of 3,000 people? What is the total revenue at that price? What is the total revenue if the price is $20?
b. Write the revenue function as a function of attendance, q, at the amusement park.
c. What attendance maximizes revenue?
d. What price should be charged to maximize revenue?
e. What is the maximum revenue? Can we determine the corresponding profit?
Answer:
Step-by-step explanation:
From the information given:
p = 70 - 0.02q
when:
q = 3000
p = 70 - 0.02 (3000)
p = 70 - 60
p = 10 dollars
The total revenue = price × number of people
= 10 × 3000
= 30000 dollars
If the price is $20
20 = 70 - 0.02q
0.02q = 70 - 20
0.02q = 50
q = 50/0.02
q = 2500
∴
If price is $20, The total revenue = 20 × 2500
= 50000 dollars
b)
The revenue function R = price × attendance
R = p × q
R = (70 - 0.02q)q
R = 70q - 0.02q²
c)
R(q) = 70q - 0.02q²
Taking the differential of the value on the right hand side.
R'(q) = 70 × (1) - 0.02 × (2q)
R'(q) = 70 - 0.04q
If we set R'(q) = 0
70 - 0.04q = 0
70 = 0.04q
q = 70/0.04
q = 1750 (critical point)
R"(q) = 0 - 0.04 × 1
R"(q) = -0.04
R"(1750) = -0.04 < 0
∴
R is maximum when q = 1750
d)
At q = 1750
p = 70 - 0.02(q)
p = 70 - 0.02(1750)
p = 70 - 35
p = 35 dollars
e)
R(q) = 70q - 0.02q² because R is max at q = 1750
R(1750) = 70 × 1750 - 0.02 × (1750)²
R_(max) = 122500 - 61250
R_(max) = 61250 dollars
Given that the actual price is 20 dollars when the price is changed to 35 dollars, we have a maximum revenue of:
Suppose:
p = 20 and q = 2500 (from a)
Then;
R = p × q
R = 20 × 2500
R = 50000 dollars
If R = 35, then q = 1750
R_{max} = 35 × 1750
R_{max} = 61250 dollars
∴
Profit = R_{max} - R
Profit = 61250 - 50000
Profit = 11250 dollars
the substitution method.
y = -4x + 15
-4x + 7y = 9
Answer: {y,x} = {3,3}
Step-by-step explanation:
1] y=-4x+15
[2] -4x+7y=9
Equations Simplified or Rearranged :
[1] y + 4x = 15
[2] 7y - 4x = 9
Graphic Representation of the Equations :
4x + y = 15 -4x + 7y = 9
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = -4x + 15
// Plug this in for variable y in equation [2]
[2] 7•(-4x+15) - 4x = 9
[2] - 32x = -96
// Solve equation [2] for the variable x
[2] 32x = 96
[2] x = 3
// By now we know this much :
y = -4x+15
x = 3
// Use the x value to solve for y
y = -4(3)+15 = 3
Solution :
{y,x} = {3,3}

Find the acute angle between the lines. 5x ? y = 2, 6x + y = 6
Answer:
Acute angle Ф = 20.77° (Approx)
Step-by-step explanation:
Given:
5x - y = 2
6x + y = 6
Find:
Acute angle
Computation:
5x - y = 2
6x + y = 6
So,
y = 5x - 2.....eq1
y = -6x + 6......eq2
Slop line y = mx + c
On comparison
m1 = 5 , m2 = -6
So,
TanФ = I(m1-m2)/(1+m1m2)I
TanФ = I(5+6)/(1-30)I
TanФ = 11/29
Ф = 20.77° (Approx)
Acute angle Ф = 20.77° (Approx)

Answer:
1) The distance between points is: [tex]\sqrt{290}[/tex]
Option B is correct option.
2) The distance between points is: [tex]\sqrt{10}[/tex]
Option A is correct option.
Step-by-step explanation:
Find the distance between points
Question 1
(8,-5),(-3,8)
The formula used is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have [tex]x_1=8, y_1=-5,x_2=-3,y_2=8[/tex]
Putting values and finding distance
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-3-8)^2+(8-(-5))^2}\\Distance=\sqrt{(-11)^2+(8+5)^2}\\Distance=\sqrt{(-11)^2+(13)^2}\\Distance=\sqrt{121+169}\\Distance=\sqrt{290}[/tex]
So, the distance between points is: [tex]\sqrt{290}[/tex]
Option B is correct option.
Question 2
(-1,6),(-4,-7)
The formula used is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have [tex]x_1=-1, y_1=6,x_2=-4,y_2=-7[/tex]
Putting values and finding distance
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-4-(-1))^2+(-7+6)^2}\\Distance=\sqrt{(-4+1)^2+(-1)^2}\\Distance=\sqrt{(-3)^2+(-1)^2}\\Distance=\sqrt{9+1}\\Distance=\sqrt{10}[/tex]
So, the distance between points is: [tex]\sqrt{10}[/tex]
Option A is correct option.

show that (0.8a+0.4b)^2=(0.8a-0.4b)^2+1.28ab
please help me solve this asap
Step-by-step explanation:
first
(0.8a+0.4b)^2= (0.8a+0.4b) *(0.8a+0.4b)
=
0.64 a^2 + 0.32 ab +0.32ab + 0.16 b^2=
0.64 a^2 + 0.64ab + 0.16 b^2
second
(0.8a-0.4b)^2+1.28ab
= 0.64 a^2 - 0.64ab +0.16 b^2 + 1.28ab
= 0.64 a^2 + 0.64ab + 0.16 b^2
since the first (left parameters ) equals the second(right side parameters)

F(x)=2x^3-2x+1 relativeminimum
Step-by-step explanation:
F(x) = 2x³ - 3x + 1.
d/dx [2x³ - 3x + 1] = 6x² - 3.
Firstly, we wish to find the stationary points of F(x).
When 6x² - 3 = 0, x = -0.707 or x = 0.707.
Now we use Second Derivative test:
d/dx [6x² - 3] = 12x.
Since 12(-0.707) < 0, x = -0.707 is a relative maximum point.
Since 12(0.707) > 0, x = 0.707 is a relative minimum point.
Hence x = 0.707. To find the exact point you can substitute the value of x back into the equation 2x³ - 3x +1.
