Write equations for the horizontal and vertical lines passing through the point (8,5)
horizontal line:
vertical line:
Answers:
Horizontal Line: y = 5
Vertical Line: x = 8
=================================================
Explanation:
All horizontal lines are of the form y = k, for some constant k. We want the horizontal line to pass through (8,5), meaning every point on this horizontal line must have y coordinate 5. Therefore, y = 5 is the equation of the horizontal line. Two such points on this line are (1, 5) and (8, 5). All that matters is the y coordinate is 5. The x coordinate can be anything you want. The slope of any horizontal line is 0.
Flipping things around, all vertical lines will have the x coordinate of each point be the same value. Draw a vertical line through (8,5) and note how each point has x coordinate of 8. Two such points are (8,1) and (8,5). Therefore, the equation of the vertical line is x = 8. The y coordinate can be any value you want. The slope of any vertical line is undefined. Unlike the horizontal line, we cannot write this equation in slope intercept form (namely because the slope isn't defined).

what is this in slope intercept form? (y=mx+b)
Answer:
y = -4/5x + 2
Step-by-step explanation:
y = -4/5x + b
(-2) = -4/5(5) + b
-2 = -4 + b
2 = b
Answer: y=-4/5x+2
Step-by-step explanation:
To write in slope-intercept form, you have the slope and y-intercept. Since we are given slope, you want to use the given point to find the y-intercept.
-2=-4/5(5)+b [multiply]
-2=-4+b [add both sides by 4]
b=2
Now that we have the y-intercept, we know the equation is y=-4/5x+2.

the intensity in the interference pattern of n identical slits is given by i=i0[sin(nϕ/2)sin(ϕ/2)]2.
The intensity in the interference pattern of n identical slits is given by the formula:
I = I₀ [sin(nϕ/2) sin(ϕ/2)]²
Here's a step-by-step explanation of the terms in this formula:
1. I is the intensity at a point in the interference pattern.
2. I₀ is the maximum intensity at the center of the pattern (i.e., when ϕ = 0).
3. n is the number of identical slits.
4. ϕ is the phase difference between the waves from adjacent slits at the point being considered.
To find the intensity at a specific point in the interference pattern, you need to know the values of I₀, n, and ϕ. Then, you can simply plug these values into the formula and calculate the intensity I.

An equation, in slope-intercept form, for the line of best fit for the table above is y = 0.05x + 0.7.
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.First of all, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (1.3 - 1.1)/(4 - 8)
Slope (m) = -0.2/4
Slope (m) = 0.05
At data point (8, 1.1) and a slope of 0.05, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 1.1 = 0.05(x - 8)
y = 0.05x - 0.4 + 1.1
y = 0.05x + 0.7

1. Suppose you roll two, regular dice with a single throw. What
is the probability of either of the two die landing on 4?
A. 1 / 3
B. 1 / 36
C. 1 / 2
D. 2 / 3
The probability of either of the two die landing on 4 is 1/36.
To calculate the probability of either of the two dice landing on 4 when rolling two regular dice, we need to determine the favorable outcomes and the total possible outcomes.
Favorable outcomes: There are three ways to get a 4 with two dice: (1, 3), (3, 1), and (2, 2).
Total possible outcomes: Each die has 6 sides, so there are 6 possible outcomes for the first die and 6 possible outcomes for the second die.
Therefore, the total possible outcomes are 6 x 6 = 36.
Probability = Favorable outcomes / Total possible outcomes
Probability = 1/6 x 1/6
Probability = 1/36

Problem. 7: A baseball diamond is a square whose sides are 90 feet long. Suppose a player running from second base to third base has a speed of 30 feet per
second at the instant he is 20 feet from third base. At what rate is the player's distance from home plate changing at that instant?
? feet per second
The player's distance from home plate changing at that instant is 37.42 feet per second.
What is Velocity?The distance covered by an object in unit time.
First, let's define a few variables.
t = time
x = Distance the player is from third base = 20 feet
dx/dt = Velocity the player is running towards third base = -30 fps
y = Distance between the player and home plate
dy/dt = Rate of change between the player's distance from home plate (This is the answer to our problem)
By Pythagorean theorem
y² = x² + 90²...(*)
Put x = 20
y² = 20² + 90²
y = 92.2 feet
Apply differentiation to (*)
2ydy/dt = 2xdx/dt + 90²
And let's plug in x, y, and dx/dt to solve for dy/dt.
2(92.2)dy/dt = 2×20×-30 + 90²
dy/dt = 37.42 feet per second
Hence 37.42 feet per second is the player's distance from home plate changing at that instant

1.7 cm × 1.7 cm × 1.7 cm box with its edges aligned with the xyz-axes is in the electric field e⃗ =(370x 150)i^n/c , where x is in meters.
The net flux through the box is zero, which means that the total electric charge enclosed by the box is also zero.
Describe Flux?Flux is a concept that arises in various fields of physics and engineering, including electromagnetism, fluid mechanics, and thermodynamics. In general, flux refers to the flow of some physical quantity across a surface or through a volume.
Let's first consider the face with normal vector in the positive x direction. The area of this face is (1.7 cm)² = 0.0289 m².
The electric field is given by e⃗ =(370x 150)i^n/c where x is the distance from the origin along the x-axis.
On this face, x ranges from 0 to 0.017 m.
Therefore, the flux through this face is:
\(Φ_x = \int\int E · dA = \int \int e_x dA\)
\(= \int \int e_x dx dy\)
= ∫0⁰⁰¹⁷ ∫0 ⁰⁰¹⁷(370x) dx dy
= (370/2) (0.017)²
= 5.8775 × 10^⁻⁵ N·m²/C
The faces with normal vectors in the positive y and z directions have the same area and the same integral, so the total flux through these three faces is:
Φ_xyz = 3 Φ_x = 1.76325 × 10⁻⁴ N·m²/C
Similarly, the faces with normal vectors in the negative x, y, and z directions also have the same integral, which is equal in magnitude but opposite in sign to the integral for the corresponding positive faces. Therefore, the total flux through these three faces is:
Φ_-xyz = -3 Φ_x
= -1.76325 × 10⁻⁴ N·m²/C
The net flux through the entire box is the sum of the fluxes through all six faces:
Φ_net = Φ_xyz + Φ_-xyz
= 0 N·m^2/C
Therefore, the net flux through the box is zero, which means that the total electric charge enclosed by the box is also zero.

How do you calculate compounded continuously?
The final amount you will have in the account after 5 years of continuous compounding at an annual interest rate of 10% is approximately $824.36.
Using the formula for continuously compounded interest, we can calculate the final amount you will have in the account after 5 years:
\(A = P x e^(rt)\)
where:
P = $500 (the initial investment)
r = 0.10 (the annual interest rate as a decimal)
t = 5 (the time period in years)
Substituting the values into the formula, we get:
\(A = $500 x e^(0.10 x 5)\)
\(A = $500 x e^(0.50)\)
A = $500 x 1.6487 (rounded to 4 decimal places)
A = $824.36 (rounded to the nearest cent)
Therefore, the final amount you will have in the account after 5 years of continuous compounding at an annual interest rate of 10% is approximately $824.36.
