2x+4y+4z = 0 is an equation of a plane containing the line .
What's the plane's reply?
In geometry, a plane is a surface made up of all the lines that are parallel to one another and connect any two locations on it. The surface is level or flat, to put it another way.
A plane is defined uniquely through any of the following in a Euclidean space of any number of dimensions: with the aid of three non-collinear points.
Parallel line equation: 2x+4y+4z = d
Point ⟨−4,−3,4⟩ belong to this plane 2 * -4 + 4 * -3 + 4 * 4 = d; d = -4
So, this plane equation 2x+4y+4z = -4
Let check point when t = 1 we have point ⟨−4,4,−2⟩
We check now if it belong to plane: 2 * -4 + 4 *4 + 4 * -2 = 0, 0 = 0.
So, equation of plane 2x+4y+4z = 0

Find the slope using points: (-10, 6) and (-5, 8)
Answer:
Step-by-step explanation:
The slope of a line can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line. Plugging in the given points, we get:
slope = (8 - 6) / (-5 - (-10)) = 2 / 5 = 0.4
So the slope of the line through the points (-10, 6) and (-5, 8) is 0.4

Choices:
0 < x < 6
0 < x < 24
0 < x < 64
0 < x < 248
The domain of the function f(x) = 10x + 8 will be all x values such that 0 ≤ x < 248.
The domain of a function is the set of all possible input values for which the function is defined. For the function f(x) = 10x + 8, the domain will be all real numbers greater than or equal to 0. This can be seen by examining the equation: if x = 0, then f(x) = 8. Therefore, the domain of the function will be all x values such that x ≥ 0. To calculate the upper bound for the domain, we can solve for x by subtracting 8 from both sides of the equation, resulting in 10x = -8. Dividing both sides by 10 gives us x = -0.8. Therefore, the domain of the function f(x) = 10x + 8 will be all x values such that 0 ≤ x < 248.

Write a function for this new half-life time (assuming a peak level of 80 mg of caffeine) Determine the amount of caffeine in the bloodstream after: 1 hour? 5 hours? 10 hours? 20 hour?
The amount of caffeine in the bloodstream after different times decreases following an exponential decay pattern.
What is caffeine?Caffeine is a natural chemical with stimulant effects.
Let's call the new half-life time for an individual with extended half-life as t. The function for the amount of caffeine (C) in the bloodstream after time t can be expressed as:
C(t) = 80 * (1/2)^(t/8)
Using this formula, we can determine the amount of caffeine in the bloodstream after different times:
1 hour:
C(1) = 80 * (1/2)^(1/8) = 80 * (1/2)^0.125 ≈ 79.28 mg
5 hours:
C(5) = 80 * (1/2)^(5/8) ≈ 64.51 mg
10 hours:
C(10) = 80 * (1/2)^(10/8) ≈ 51.37 mg
20 hours:
C(20) = 80 * (1/2)^(20/8) ≈ 25.68 mg

Step-by-step explanation:
When marginal revenue is negative for a linear (inverse) demand function, increases in output will cause total revenues to:
a. increase
b. decrease
c. remain unchanged
d. there is not sufficient information to classify the elasticity of demand
Marginal Revenue is negative, the firm should consider reducing its output to increase its total revenue.
Therefore, correct answer will be a. increase.
Marginal Revenue (MR) is a crucial concept in economics that measures the change in a firm's total revenue as a result of selling one additional unit of output. MR is used by firms to make decisions about how much output to produce and what price to charge.
In a linear (inverse) demand function, MR is negative when the elasticity of demand is less than one, meaning that the demand for a product is relatively inelastic. In other words, as the firm increases output, the price will decrease, causing total revenue to decline.

find the curvature. r(t) = 9t i 7t j (2 t2) k
The curvature of a curve r(t) = 9t i 7t j (2 t2) k is 4 × ||9 i + 7 j|| / (9² + 7² + 4t²)^(3/2).
What do you mean by curvature?Curvature is a measure of the amount by which a curve deviates from being straight. It describes the degree to which a curve bends or twists at any point along its length.
In mathematics, curvature is a property of curves and surfaces that is used to describe their shape and local behavior. For example, the curvature of a circle is constant and is equal to the reciprocal of its radius. The curvature of a straight line is zero.
Curvature is a scalar quantity and is usually measured in units of inverse length, such as 1/meter. There are several ways to mathematically define and calculate curvature, including the concept of the curvature of a curve at a point, which is the rate of change of the direction of the tangent to the curve at that point.
The curvature of a curve is given by:
k(t) = ||r'(t) x r''(t)|| / ||r'(t)||³
where r'(t) is the first derivative of r(t), r''(t) is the second derivative of r(t), and || || is the magnitude or length of a vector.
Given the curve r(t) = 9t i + 7t j + (2 t²) k, we can find its first and second derivatives:
r'(t) = 9 i + 7 j + 4t k
r''(t) = 4 k
So, the curvature of the curve r(t) is:
k(t) = ||r'(t) x r''(t)|| / ||r'(t)||³ = ||9 i + 7 j|| × ||4 k|| / ||9 i + 7 j + 4t k||³ = 4 × ||9 i + 7 j|| / (9² + 7² + 4t²)^(3/2)
Since this expression depends on t, the curvature is a function of t, not a constant.

We can now add 10 times the second equation to the third equation, and the result is
[tex]\begin{bmatrix}1 & -3 & 4 \\ 0 & -10 & 15 \\ 0 & 0 & -35\end{bmatrix}\begin{bmatrix}x_1 \\ x_2 \\ x_3\end{bmatrix}[/tex]
=[tex]\begin{bmatrix}-4 \\ -20 \\ 20\end{bmatrix}[/tex]
We can now solve for [tex]$x_3$[/tex] by dividing the third equation by -35, and the result is = [tex]\frac{20}{-35} = -\frac{20}{35}$.[/tex]
Therefore, the solution of the system of equations is

Your realized income from your primary job is 2,034. 24/month. Your fixed expenses are 30% of your primary jobs realized income. You have a second job that pays $9. 50/hr with deductions of FICA (7. 65%), federal tax withhold (11. 5%), and a state tax withholding (7. 75%). If you want to save enough in the next 10 months to have an emergency fund that will cover 5 months using only 20% of your discretionary monies from your primary job, how many hours per month do you need to work at your second job to meet your monthly savings goal?
You need to work 84 hours per month at your second job to meet your monthly savings goal.
Fixed expenses = 2,034.24 x 30% = $610.72
Discretionary income = 2,034.24 - 610.72 = $1,423.52
Savings goal per month = $1,423.52 x 20% = $284.70
Net pay per hour = $9.50 - ($9.50 x 7.65%) - ($9.50 x 11.5%) - ($9.50 x 7.75%) = $7.33
Hours per month = $284.70 ÷ $7.33 = 84 hours.
To calculate, first find the number of your fixed expenses by multiplying your primary job income by 30%. This is $610.72. Then subtract your fixed expenses from your primary job income to find your discretionary income, which is $1,423.52. Multiply that by 20% to find the amount you want to save each month, which is $284.70.
Finally, divide that amount by your net pay per hour after taxes from your second job, which is $7.33, to find the number of hours you need to work, which is 84 hours.

The area of the pool is 113.04 ft².
How to find the area of the pool?The diagram shows a circle inside a square. The circular surface is the pool and it is surrounded by the square deck. The diameter of the pool can be chosen from 12 to 24 feet.
The blue shaded region is the area of the pool. Therefore, let's find the area of the pool as follows:
area of the pool(area of a circle) = πr²
where
r = radius of a circleTherefore,
r = diameter / 2 = 12 / 2 = 6 feet
Hence,
area of the pool(area of a circle) = 3.14 × 6²

Welcome to the land down under! Spend the day sailing
in Sydney Harbor! Sailboats are made up of two sails,
the mainsail and the headsail. Typically, these sails are
the shape of triangles and these two triangles are
similar. Considering the sailboat pictured below,
determine the value of x and y and the unknown side
lengths.
6+A
X-2
30 ft
5y-3
26 ft
The value of x is 15
The value of y is 7.
The unknown sides:
x = 15
5y - 3 = 33
y + 9 = 16
x - 2 = 13
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Similar triangles mean the ratios of the corresponding sides are equal.
Now,
(5y - 3)/(y + 9) = 30/x = 26/(x - 2)
Taking two ratios.
(5y - 3)/(y + 9) = 30/x
5xy - 3x = 30y + 270
Taking two ratios.
30/x = 26/(x - 2)
30x - 60 = 26x
30x - 26x = 60
4x = 60
x = 15
Now,
Substituting x = 15
5xy - 3x = 30y + 270
5 x 15 x y - 3 x 15 = 30y + 270
75y - 45 = 30y + 270
75y - 30y = 270 + 45
45y = 315
y = 7
Now,
x = 15
5y - 3 = 35 - 3 = 33
y + 9 = 7 + 9 = 16
x - 2 = 15 - 2 = 13
Thus,
x is 15 and y is 7.
The unknown sides are 15, 33, 16, and 13.

Answer:
Step-by-step explanation:
Since the numerator is missing, you want to multiply the denominator onto the other side.
5 x 7 =35
x=35
Answer:
x=35
Step-by-step explanation:
Easy way to solve is making x/5 an improper fraction (fraction whose numerator is equal to or greater than its denominator.)
How I solved it was by multiplying 7×5=35, then I plugged the value into x making it (35/5)=7.
Now just make it a proper fraction, 35÷5=7, now we have 7=7.
Which graph is a function of x?
Which is the graph of f(x) = 2(3)?
The graph of the exponential function:
f(x) = 2*(3)^x
Is the first one.
Which one is the graph of f(x) = 2*(3)^x?We want to find the graph of the exponential function:
f(x) = 2*(3)^x
To identify it, you can evaluate the function in some different values of x.
if x = 0
f(0) = 2*(3)^0 = 2
if x = 1
f(1) = 2*3^1 = 6
if x = 2
f(2) = 2*(3)^2 = 18
So we have the 3 points:
(0, 2), (1, 6), (2, 18)
The only graph that passes through these points is the first one, so that is the correct option.

If two line segments are parallel to each other and the first line segment has endpoints at (2, 3) and (1,9) while the second line segment has endpoints at (5, 4) and (3,Y), the value of y is:
16
Two lines are parallel if and only if they have the same slope. So, to find the value of y, we need to find the slope of the first line segment and use it to find the equation of the second line segment.
The slope of the first line segment can be found using the formula:
Slope = (y2 - y1) / (x2 - x1)Slope = (9 - 3) / (1 - 2) = 6 / -1 = -6)Since the two lines are parallel, they have the same slope, so we can use the slope to find the equation of the second line segment.
y - y1 = m(x - x1)y - 4 = -6(x - 5)Expanding the equation and solving for y, we get:
y = -6x + 34Now that we have the equation of the second line segment, we can use the x-coordinate of one of its endpoints (3) to find the corresponding y-coordinate.
y = -6(3) + 34y = 16So, the value of y is 16.
