Answer:
The cat weighs 2860 g more
Step-by-step explanation:
Convert the cats weight (3.1 kg) to grams.
Subtract the cats weight and the parakeets weight to find total.
In this case 3100 g (cats weight) - 240 g (parakeets weight) = 2860 g

Answer:
b = 6
c = 9
Step-by-step explanation:
if triangles PQR and JHI are congruent, then (b + 48) must equal 9b
9b = b + 48
8b = 48
b = 6
if triangles PQR and JHI are congruent, then (c + 9) must equal 2c:
2c = c + 9
c = 9
One spring day, Caroline noted the time of day and the temperature, in degrees
Fahrenheit. Her findings are as follows: At 6 a.m., the temperature was 52° F. For the
next 3 hours, the temperature rose 2° per hour. For the next 6 hours, it rose 1° per
hour. The temperature then stayed steady until 6 p.m. For the next 3 hours, the
temperature dropped 1° per hour. The temperature then dropped steadily until the
temperature was 60° at midnight. On the set of axes below, graph Caroline's data.
Answer:
Please see attached graph
Step-by-step explanation:
In the attached image you will find the red dots hour per hour that reflect the temperature changes described in the text. The finer red line joins the points to give continuity to the graph.
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)

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

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.
what is the equation of the line in point slope form that has a slope of -7/8, going through point (12,-3)
Answer:
y= (-7/8)x +7.5
Step-by-step explanation:
We know that the form for the equation of a line is
y= mx+b, with m being the slope, so our equation is
y=(-7/8)x+b. As b should be a constant, we need to find b. Plugging (12,-3) in, we have -3 = (-7/8)(12)+b = -10.5+b. Adding 10.5 to both sides, we get b= 7.5, making our equation
y= (-7/8)x +7.5

(100+30x)
30.rº
Answer:
x = 1[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
As you can see, the two angles are supplementary as they lie on the same straight line so they should add up to 180°.
100 + 30x + 30x = 180
Evaluate like terms.
60x + 100 = 180
Isolate 60x.
60x = 180 - 100
= 80
Find x.
x = 80 ÷ 60
x = 1[tex]\frac{1}{3}[/tex]

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.

slope intercept form
[tex]y = \frac{x}{8} + \frac{31}{8}[/tex]
Step-by-step explanation:
Explanation:-
Given equation of the line
y = 1/8x-4
8 y = x - 32
x - 8 y -32=0
The equation of the line is parallel to the given line a x + b y + k=0
x - 8 y + k=0
This line is passing through the point ( 1,4)
x - 8 y + k=0
1 - 32 + k =0
k = 31
The equation of the line is parallel to the given line and passing through the point C( 1,4) is x - 8 y + 31=0
slope intercept form
8 y = x + 31
[tex]y = \frac{x}{8} + \frac{31}{8}[/tex]
