The equation of the line that is perpendicular to 5x-8y=-6 and passes through (4,-4) is y = (-8/5)x + 16/5.
What are Parallel lines?Parallel lines are two or more lines in a coordinate plane that are equidistant from each other at all coordinates.
The given line can be rewritten in slope-intercept form as y=(5/8)x+(3/4), where the slope is 5/8. So, any parallel line will also have a slope of 5/8.
Using the point-slope form of a line, we can write the equation of the line as:
y - (-4) = (5/8)(x - 4)
Simplifying, we get:
y = (5/8)x - 23/8
Therefore, the equation of the line that is parallel to 5x-8y=-6 and passes through (4,-4) is y = (5/8)x - 23/8.
The slope of the given line is 5/8, so the slope of any line perpendicular to it will be -8/5.
y - (-4) = (-8/5)(x - 4)
Simplifying, we get:
y = (-8/5)x + 16/5
Therefore, the equation of the line that is perpendicular to 5x-8y=-6 and passes through (4,-4) is y = (-8/5)x + 16/5.

Decide whether Rolle's Theorem can be applied to f(x) = x2 - 3 on the interval [-2, 2]. If Rolle's Theorem can be applied, find all value(s) of c in the interval such that f '(c) = 0. Rolle's theorem can be applied; c = 0
Rolle's theorem can be applied; c = -2, 2
Rolle's theorem cannot be applied because f '(c) ≠ 0
Rolle's theorem cannot be applied because f(-2) ≠ f(2)
Therefore , the solution of the given problem of function comes out to be the value of c for which f'(c) = 0 in the interval [-2, 2] is c = 0.
Explain Function.The study of numbers and their variable, as well as in out environment, architecture, and both real and imagined places, are all covered in the mathematics curriculum. A function range illustrates visually how the amounts of the inputs and the corresponding outputs for each are related. Simply stated, a function is a set of inputs that, when combined, produce specific outputs for each input. Each position is given a locale, region, or range.
Here,
Rolle's Theorem can be applied to $f(x) = x^2 - 3$ on the interval [-2, 2]. This is because f(x) satisfies the following conditions of Rolle's Theorem:
1 ) f(x) is continuous on the interval [-2, 2]
2 ) f(x) is differentiable on the interval (-2, 2)
3) f(-2) = 1 and f(2) = 1
Since f(-2) = f(2), there must exist at least one point c in the interval (-2, 2) such that f'(c) = 0.
Taking the derivative of f(x) with respect to x, we get f'(x) = 2x. Setting f'(c) = 0, we have:
2c = 0
Solving for c, we get c = 0.
Therefore, the value of c for which f'(c) = 0 in the interval [-2, 2] is c = 0.

Answer:
2^4*2^5=2^(4+5)=2^9
Step-by-step explanation:
When dealing with operations with exponents and multiplication, the exponent operations always come first. So while the exponent 9 is correct for the answer, 4 is incorrect.
For example, if you were to solve each operation and eliminate every exponent, you would have
2^4*2^5=16*32=512 which is the same as 2^9=512.
As you can see, the exponent operation must come before the multiplication.

Ghana Railways Co-operation has 20 trains for its operation. It is observed that x trains can
accommodate 2 passengers, y trains 3 passengers and z trains 5 passengers. However, the total
number of passengers always present at Ghana Railways is 64. During market day, 3 of x trains, 2
of y trains and 4 of 2 trains for a total of 10 trains were used. Determine the values of x, y and z.
The number of trains that can accommodate 2 passengers is x = 32, the number of trains that can accommodate 3 passengers is y = 1, and the number of trains that can accommodate 5 passengers is z = -11.
What do you mean by equation?It is represented by an equal sign (=) and consists of variables, numbers, and mathematical operations. Equations are used to describe relationships between different quantities and can be solved to find unknown values. For example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving 2x = 4, and then dividing both sides by 2, giving x = 2.
Let x, y and z be the number of trains that can accommodate 2 passengers, 3 passengers and 5 passengers, respectively.
From the information given, we have:
x + y + z = 20 (the total number of trains)
2x + 3y + 5z = 64 (the total number of passengers)
We also know that 10 trains were used during market day:
3 of the x trains, 2 of the y trains and 4 of the z trains.
So, we have:
2x + y + 5z = 10
Solving these three equations simultaneously, we can find the values of x, y and z:
Subtracting the first equation from the third equation:
0 + y + 4z = -10
y + 4z = -10
Subtracting 2 times the first equation from the second equation:
-x + 3y + 4z = 32
y + 4z = 42
Subtracting the last two equations:
x = 32
Substituting the value of x back into the first equation:
32 + y + z = 20
y + z = -12
Substituting the value of y and z back into the third equation:
2x + y + 5z = 10
64 + y + 5z = 10
y + 5z = -54
Solving these two equations simultaneously, we can find the values of y and z:
Subtracting the second equation from the last equation:
4z = -44
z = -11
Substituting the value of z back into the second equation:
y + 5z = -54
y - 55 = -54
y = 1
Therefore, the number of trains that can accommodate 2 passengers is x = 32, the number of trains that can accommodate 3 passengers is y = 1, and the number of trains that can accommodate 5 passengers is z = -11.

A child is flying a kite. If the kite is "h" feet above the child's hand level and the wind is blowing it on a horizontal course at "v" feet per second, the child is paying out cord at _____ feet per second when "s" feet of cord are out. Assume that the cord remains straight from hand to kite.
The child is paying out cord at a rate of s(ds/dt)) /√(s²-h²) feet per second when "s" feet of cord are out.
What is Differential equation?A differential equation is an equation that contains one or more functions with its derivatives.
The distance between the kite and the child's hand level "d".
By using the Pythagorean theorem, we can write:
d² + h² = s²
Simplifying and solving for d, we get:
d² = s²-h²
d = √(s²-h² )
Let's call the length of the cord "L". Then, we can write:
d² + L² = s²
Differentiating both sides with respect to time (t), we get:
2d (dd/dt) + 2L (dL/dt) = 2s (ds/dt)
We want to find (dL/dt) when L = s and d = √(s²-h² )
(dd/dt) = 0 as the height of the kite above the child's hand level is constant.
(dL/dt) = (s(ds/dt) - d (dd/dt)) / L
Substituting in the values we found for d and L, we get:
(dL/dt) = s(ds/dt)) / √(s²-h² )
Therefore, the child is paying out cord at a rate of s(ds/dt)) /√(s²-h²) feet per second when "s" feet of cord are out.

Where the ordered pair (h, k) is the center of the circle.
Given (h, k) = (-6, -2)
We also have that the circle passes through a point (7, 12)
Which means that (7, 12) lies on the circumference of the circle.
Let this be labelled as [tex](x_{1}, y_{1})[/tex]
Since this point lies on the circumference of the circle, it must satisfy the equation when substituted in for (x, y).
Thus, we substitute [tex]x_{1}[/tex] for x and [tex]y_{1}[/tex] for y.
We get the final equation to be:

A house that costs $200,000 will appreciate in value by 3% each year.
Write a function that models the cost of the house over time. Use x for years and y for
the value of the house, in dollars.
Find the value of the house at the end of ten years.
Answer: The function that models the cost of the house over time can be written as y = 200,000 * (1 + 0.03)^x, where x is the number of years and y is the value of the house.
To find the value of the house at the end of ten years, we need to plug in x = 10 into the function:
y = 200,000 * (1 + 0.03)^10 = 200,000 * 1.33489 = 266,978.8

The coordinate plane shown below is a graph of a relation.
What is the range of the graph?
The range of the function, given the graph of a relation, can be found to be −2 ≤ y ≤ 7 .
How to find the range of a graph ?Graphs can be used to determine a function's domain and range. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The y-axis on a graph represents the possible output values, or range.
The range here would therefore be the y - values that the relations fall within. The lowest y - value is - 2 as no relation goes below this. The highest y - value is 7.
The range is therefore -2 ≤ y ≤ 7.

Two ordinary fair dice are thrown. The resulting score is found as follows.
• If the two dice show different numbers, the score is the smaller of the two numbers.
• If the two dice show equal numbers, the score is 0.
(i) Draw up the probability distribution table for the score.
The probability distribution table is shown below
How to determine the probability distribution tableFrom the question, we have the following parameters that can be used in our computation:
Dice = 2
This means that
Sample size = 6 * 6
Sample size = 36
So, the number of outcomes is 36
To determine the distribution table, we need to identify that the dice are distinct.
This means that (1, 2) and (2, 1) are not the same outcomes
We can create a probability distribution table for the score by listing all possible outcomes and their probabilities, and then determining the score for each outcome based on the rules given.
So, we have
Outcomes Probability
(1, 1) 1/36
(1, 2) 1/36
(1, 3) 1/36
(1, 4) 1/36
(1, 5) 1/36
(1, 6) 1/36
........
(6, 1) 1/36

A car can be rented for $80 per week plus $0.25 per mile. How many miles can be driven if you have at most $110 to spend for weekly transportation?
Answer: Let x be the number of miles driven.
The cost of renting the car and driving x miles is 80 + 0.25x.
We want to find the maximum number of miles that can be driven given a budget of $110, so we set 80 + 0.25x = 110 and solve for x:
80 + 0.25x = 110
0.25x = 110 - 80
0.25x = 30
x = 120
So the maximum number of miles that can be driven is 120.

a) The value of the bulldozer at any time t should be given by the equation,
V = 140500- 5600t
b) The value of the bulldozer after 7 years is $1,01,300
What is an equation?
An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.
a)To answer the problem above, we make the assumption first that the depreciation is a straight-line method in order to solve for the depreciation rate.
d = (140500 - 17300)/ 22 = 5600
The value of the bulldozer at any time t should be given by the equation,
V = 140500- 5600t
b) Substitute t=7 into the equation
V = 140500- 5600(7)
= 140500- 39200
= 1,01,300
The value of the bulldozer after 7 years is $1,01,300
