Answers
Answer:
Part A
2 hours 10 minutes
Part B;
Please find attached a number line created with MS Visio
Part C
The completed explanation is given as follows
The second showing starts at 7:35 p.m. The movie lasts 2 hours 10 minutes so it ends 9:45 p.m. So the second sowing be over by 9:45 p.m
Step-by-step explanation:
Part A
The given parameters are;
The time the first showing starts, t₁ = 4:35 p.m.
The time the first showing starts, t₂ = 7:15 p.m.
The time interval between shows, [tex]t_{interval}[/tex] = 1/2 hours = 30 minutes
Let 'x' represent the video in minutes, we have;
x = 7:15 - 4:35 - 30 = 2 hours 40 minutes - 30 minutes = 2 hours 10 minutes
The length of the video = 2 hours 10 minutes
Part B;
Using the number line, we have;
1) Plotting the points for the starting and points for the two showing points which are 4:35 pm. and 7:15 p.m.
2) Plot the point 30 minutes before the start of the second movie which is 6:45 p.m and find the time difference between the start of the first showing and the point 6:45 p.m. which gives the length of the movie which is 2 hours and 10 minutes
3) Given that the second showing starts 20 minutes late, the second showing will start at 7:15 p.m. + 20 min = 7:35 p.m.
4) The second showing ends at 7:35 p.m. + 2 hours 10 minutes = 9:45 p.m.
Therefore, the second showing will be over 9:35 p.m.
Part C
The second showing starts at 7:35 p.m. The movie lasts 2 hours 10 minutes so it ends 9:45 p.m. So the second sowing be over by 9:45 p.m.

Find the area of the surface obtained by rotating the circle
x2 + y2 = r 2
about the line
y = r.
Answers
The area of the surface obtained by rotating the circle [tex]x^2 + y^2 = r^2[/tex] about the line y = r is π²r² square units.
To find the area of the surface obtained by rotating the circle
[tex]x^2 + y^2 = r^2[/tex] about the line y = r, we can use the method of cylindrical shells.
The circle [tex]x^2 + y^2 = r^2[/tex] is centered at the origin (0, 0) with a radius r. The line y = r is the line y-axis but shifted up by r units.
When we rotate the circle about the line y = r, it forms a 3D shape called a torus or a donut shape.
Consider a small strip on the circle at a distance y from the line y = r.
This small strip is at a distance r - y from the y-axis.
The length of this strip is the circumference of the circle at y, which is 2πy (since the circumference of a circle is 2π times its radius).
The width of this strip is the change in x, which we can denote as dx.
The area of this small strip is then given by the product of its length and width, which is 2πy dx.
Now, to find the total surface area, we integrate this area over the range of y values from -r to r (since the circle is symmetric about the y-axis):
Total Surface Area = ∫[from -r to r] 2πy dx
Now, we need to express y in terms of x using the equation of the circle [tex]x^2 + y^2 = r^2:\\y^2 = r^2 - x^2[/tex]
y = ±√(r² - x²)
Since we are considering the upper half of the circle, we take the positive square root:
y = √(r² - x²)
Now, we can rewrite the integral with respect to x:
Total Surface Area = ∫[from -r to r] 2π√(r² - x²) dx
To solve this integral, we can make a trigonometric substitution:
Let x = r sin(θ), then dx = r cos(θ) dθ.
When x = -r, θ = -π/2, and when x = r, θ = π/2.
Now the integral becomes:
Total Surface Area = ∫[from -π/2 to π/2] 2π√(r² - (r sin(θ))²) (r cos(θ)) dθ
Total Surface Area = 2πr² ∫[from -π/2 to π/2] √(1 - sin²(θ)) cos(θ) dθ
Now, we can use the trigonometric identity:
sin²(θ) + cos²(θ) = 1
√(1 - sin²(θ)) = cos(θ)
Total Surface Area = 2πr² ∫[from -π/2 to π/2] cos²(θ) dθ
Now, use the trigonometric identity: cos²(θ) = (1 + cos(2θ))/2
Total Surface Area = 2πr² ∫[from -π/2 to π/2] (1 + cos(2θ))/2 dθ
Total Surface Area = 2πr² [θ/2 + (sin(2θ))/4] [from -π/2 to π/2]
Total Surface Area = 2πr² [(π/2 + sin(π) - (-π/2 + sin(-π)))/4]
Since sin(π) = 0 and sin(-π) = 0:
Total Surface Area = 2πr² [(π/2 - (-π/2))/4]
Total Surface Area = 2πr² (π/2)
Total Surface Area = π²r²
So, the area of the surface obtained by rotating the circle [tex]x^2 + y^2 = r^2[/tex] about the line y = r is π²r² square units.

What is the solution to 3(1-3x)=2(-4x+7)?
Answers
Answer:
x = -11
Step-by-step explanation:
3(1 - 3x) = 2(-4x + 7)
Distribute the 3.
(3 - 9x) = 2(-4x + 7)
Distribute the 2.
3 - 9x = -8x + 14
Add 8x to both sides.
3 - x = 14
Subtract 3 from both sides.
-x = 11
Multiply by -1.
x = -11.
Proof:
3(1 - 3x) = 2(-4x + 7)
3(1 - 3(-11)) = 2(-4(-11) + 7)
3(1 + 33) = 2(44 + 7)

First you need to simplify the equation, using distributive property.
Distribute -2 to the numbers within the parentheses.
-2*11 = -22
-2*-12x =24x
= 24x - 22
Then distribute -4 among 1 and -6.
-4*1 =-4

The Osborne 1 was the first laptop ever released, and it weighed 11 kg in 1981. Since then, the average rate of weight decrease has been 4.7% per year. This means that in 2019, a laptop would have weighed around 2.3 kg.
1981: 11 kg
1982: 10.5 kg (11 kg - 0.55 kg = 10.5 kg)
1983: 10.02 kg (10.5 kg - 0.48 kg = 10.02 kg)
1984: 9.55 kg (10.02 kg - 0.47 kg = 9.55 kg)
2019: 2.3 kg (3.44 kg - 1.14 kg = 2.3 kg)
The Osborne 1 was the first laptop ever released in 1981, and it weighed 11 kg. Since then, the average rate of weight decrease has been 4.7% per year. This means that the mass of a laptop decreases by 0.47 kg every year on average. So, in 1982 it would have weighed 10.5 kg, in 1983 it would have weighed 10.02 kg, and so on. By 2019, the weight of a laptop would have decreased to 2.3 kg as a result of this 4.7% average rate of weight decrease.

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in the simplest form 12,7,2,...
Answers
Answer: common difference = -5
Step-by-step explanation:
This is an arithmetic progression. The common difference will be gotten by subtracting the 1st term from the 2nd term. This will be:
1st term = 12
2nd term = 7
3rd term = 2
Common difference = 7 - 12 or 2 - 7 = -5
It isn't an geometric progression as the ratio isn't thesame
= 2nd term / 1st term
= 7/12
= 3rd term / 2nd term
= 2/7
Therefore, it's an arithmetic progression with difference of -5
Consider the quadratic function f(x) = x2 – 5x + 12. Which statements are true about the function and its graph? Select three options. The value of f(–10) = 82 The graph of the function is a parabola. The graph of the function opens down. The graph contains the point (20, –8). The graph contains the point (0, 0).
Answers
Answer:
The statement "The value of f(–10) = 82" is not true. To find the value of f(–10), we substitute –10 for x in the equation:
Step-by-step explanation:
The statement "The value of f(–10) = 82" is not true. To find the value of f(–10), we substitute –10 for x in the equation:
f(–10) = (–10)^2 – 5(–10) + 12 = 100 – (–50) + 12 = 162
The statement "The graph of the function is a parabola" is true. Because the equation of the function is of the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a is not equal to 0, the graph of the function is a parabola.
The statement "The graph of the function opens down." is true. The coefficient of x^2 is a positive value, which means the parabola opens down.
So, the true statements are
The graph of the function is a parabola.
The graph of the function opens down.
The graph does not contain the point (20, –8)

= W₁P(W₁) + W₂P(W₂) + W₃P(W₃)
= ( 0 × 0.09 ) + ( 1 × 0.42 ) + ( 2 × 0.49 )
= 0 + 0.42 + 0.98
= 1.4
Therefore, the mean of the walleye 'W' for the given number of walleye and its probability is given by 1.4.
The above question is incomplete , the complete question is :
Eva loves to go fishing. Each time she catches a fish, there is a 70% chance that it is a northern pike and a 30% chance it is a walleye. Let W be the random variable that represents the number of walleye Eva gets
if she catches 2 fish.
W : 0 1 2
P(W) : 0.09 0.42 0.49
Calculate the mean of W.

What are arithmetic operations?Addition, subtraction, multiplication, and division are the most fundamental operations in arithmetic. However, arithmetic also includes more complex operations like manipulating percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, which are analogous to logarithms. It is necessary to evaluate arithmetic expressions in accordance with the intended order of operations.
Given one yard of ribbon is 3.5 dollars
1y = 3.5
where y = yards
dollar for 5/8 yards is
1y x 5/8 = 3.5 x 5/8
5/8y = 2.1875
Hence one should pay 2.1875 dollars for 5/8 yards.
