What are the 3 different slope formulas?
The three different forms of slope formulas are m=(y-b)÷x, m=(y-y₁)÷(x-x₁), and m=(-A)÷B.
The slope gives the steepness of a straight line. The three different forms of the slope of a linear equation are slope-intercept form, point-slope form, and standard form.
From the equation of slope-intercept form y=mx+b, the slope is calculated using the formula, m=(y-b)÷x. Here, the slope is m and the y-intercept is b.
From the equation of the point-slope form (y-y₁)=m(x-x₁), the slope is calculated using the formula, m=(y-y₁)÷(x-x₁). Here, points on the line are x₁ and y₁.
From the equation of standard form Ax+By=C, the slope is m=(-A)÷B. Here, constants or integers are A, C, and B.
In general, the slope is calculated using the formula, m = (Δy)÷(Δx)= (y₂-y₁)÷(x₂-x₁). Here, in the line, the coordinate of the first point is (x₁, y₁), and the second point is (x₂, y₂).

A tree that is 3 feet tall is growing at a rate of 1 foot per year. A 5-foot tree is growing at a rate of 0. 75 foot per year. The ordered pair (t, h) represents the time in years, t, at which the trees are at height, h. Which ordered pair represents the number of years elapsed when the trees are at the same height?.
the ordered pair that represents the number of years elapsed when the trees are at the same height is (8,5). We were then asked to find the number of years elapsed when the trees are at the same height.
In this problem, we were given two different trees, one that is 3 feet tall and growing at a rate of 1 foot per year, and another that is 5 feet tall and growing at a rate of 0.75 feet per year. The ordered pair (3,1) represents the 3-foot tall tree growing at a rate of 1 foot per year and the ordered pair (5,0.75) represents the 5-foot tall tree growing at a rate of 0.75 feet per year.
To find the number of years elapsed when the trees are at the same height, we need to solve the equation:
3 + 1t = 5 + 0.75t
t = (5 - 3)/(1 - 0.75) = 2/0.25 = 8
So the ordered pair that represents the number of years elapsed when the trees are at the same height is (8,5).

The required reflection of the points N(-3, 1), G(0, 4), B(-1, 1) across the y-axis are N(3, 1), G(0, 4), B(1, 1) .
Explain reflection across y-axis.Point (x, y) is reflected across the x-axis as (x, -y). The y-coordinate stays the same when a point is reflected across the y-axis, but the x-coordinate is assumed to be the additive inverse.
According to question:We have,

for the ball's height h at time t seconds after launch is h (t) =
-4.9t2 +20.58t + 25.48, where his in meters. What is the
maximum height the ball achieves before landing?
Answer:
[tex]\boxed{47.089 \;meters} \\\\[/tex]
Step-by-step explanation:
For any function f(x), the maximum or minimum value can be determined by 1. Finding the first derivative f(x) with respect to x i.e. f'(x)
2. Setting this first derivative to 0, solving for x
3. Substituting for x in the original function to get the maximum/minimum value
[tex]\textrm{The equation for the function f(t) is }\\f(t) = -4.9t^2 + 20.58t + 25.48\\\\[/tex]
[tex]\textrm{The first derivative of this function with respect to t is }\\\\f'(t) = - 2\cdot 49t + 20.58\\= -9.8t + 25.48\\\\[/tex]
[tex]\textrm{Setting this first derivative equal to 0 gives:}\\\\-9.8t + 20.58 = 0\\\\-9.8t = -20.58 \;\;\;\;\;\textrm{(Subtracting 20.58 from both sides)}\\\\9.8t = 20.58 \;\;\;\;\;\; \textrm{ (Multiplying both sides by -1)}[/tex]
[tex]\textrm{Therefore }\\\\t = \dfrac{20.58}{9.8}\\\\t= 2.1 \textrm{ seconds}[/tex]
[tex]\textrm{Therefore, at = 2.1 seconds, the ball will reach its maximum height.}[/tex]
To find what this maximum height is, substitute t = 2.1 in the original equation and solve for h(t)
[tex]h(t)\;at\;t=2.1 \\h(2.1) = 4.9\cdot \:2.1^2+20.58\cdot \:2.1+25.48=47.089 \;meters\\\\[/tex]
[tex]\textrm{ The maximum height the ball achieves before landing is } \boxed{47.089 \;meters} \\\\[/tex]

Calculating the total VMT or VKT for all road segments during a certain time period by multiplying the daily traffic volume on each segment by its length.
How many cars in a mile of traffic jam?The average automobile is around 15 feet long, so if you multiply 5280 by this number, you get about 350 cars, assuming they are all touching. Just over 284 million automobiles were on the road in the second quarter of 2022 in the United States. Though estimating the overall number of automobiles on the planet is not a precise science, the number is rising quickly.
Given that the ACS estimated there were 150 million workers in 2016, there are at least 115 million automobiles and trucks on American roads every day.

The slope of the line passing through the equation 4x - 3y = 12 is given by Slope m = -3/4
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
4x - 3y = 12 be equation (1)
Now , on simplifying the equation , we get
Adding 3y on both sides of the equation , we get
3y + 12 = 4x
Subtracting 12 on both sides of the equation , we get
3y = 4x - 12
Divide by 3 on both sides of the equation , we get
y = ( 4/3 )x - 4
It is of the form y = mx + b where m is the slope and b is the y-intercept
So , slope m₁ = 4/3
Now , the line is perpendicular to the line y = ( 4/3 )x - 4
So , the product of their slopes is -1
And , m₁ x m₂ = -1
Substituting the values in the equation , we get
m₂ = ( 3/4 ) x -1
m₂ = -3/4
Hence , the slope of the line is -3/4

How to find the length in a line segment?A line segment is bounded by two distinct points on a line. Therefore, point D is located on the segment CE. Hence,
CD = 24 and DE = x
CE = 5x
Therefore, the measurement of the segment CE can be found as follows:
CE = CD + DE
5x = 24 + x
5x - x = 24
4x = 24
divide both sides of the equation by 4
x = 24 / 4
x = 6
Finally,
CE = 5(6) = 30
The segment XZ is bisected by the point Y. Hence,
XY = 12x
XZ = 18x - 6

Determine whether each sequence has a negative common difference. Clearly explain your reasoning.
a). The sequence as represented in question a). is not an arithmetic sequence and hence, does not have a common difference.
b). The sequence formed by recording the daily odometer reading of a car after driving 15 miles each day does not have a negative common difference.
Which sequence has a negative common difference?It follows from the task content that the sequence which has a negative common difference be determined.
It follows that the common difference, by definition is the difference between successive terms a (n) of the sequence.
Therefore, common difference is usually given by; a (n) - a (n-1).
a). Since the given sequence is; 64, 32, 16, 8, ....
Since The common difference is; 32 - 64 ≠ 16 - 32 ≠ 8 - 16.
Hence, the sequence does not have a common difference and hence, is not an arithmetic sequence.
b). For a sequence involving the daily odometer reading of a car after driving 15 miles every day.
It follows that the recursive function for such a sequence would take the form; a (n) = a (n-1) + 15.
By comparison with the standard recursive function for arithmetic sequences, a (n) = a (n-1) + 15, it follows that the common difference, d = 15.
On this note, the common difference for the sequence is not a negative number.
