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).

Answer:
x = 5, -5, 3, -3
Step-by-step explanation:
First, substitute u = x^2 into the equation, and we have
u^2 - 34u + 225 = 0
u = x^2
Factor u^2 −34u +225 using the AC method, and we get
( u - 25) ( u - 9) = 0
We know If any individual factor on the left side of the equation is equal to
0, the entire expression will be equal to 0, so
u - 25 = 0
u - 9 = 0
Next, we set u - 25 equal to 0 and solve for u, and we get
u = 25
Then set u - 9 equal to 0 and solve for u, and we get
u = 9
The final solution is all the values that make (u−25)(u−9) = 0 true.
u =25,9
Substitute the real value of u=x^2 back into the solved equation.
x^2 = 25
(x^2)^1 = 9
x^2 = 25
x = 5, -5
Now we solve the second equation
(x^2)^1 = 9
x = 3, -3
So, the answers are: 5, -5, 3, -3
A company rents paddleboards by charging a rental fee plus an hourly rate. Write an expression that represents the cost (in dollars) of renting a paddleboard for h hours.
The expression that represents the cost (in dollars) of renting a paddleboard for h hours is r + xh
How to determine the cost for h hoursFrom the question, we have the following parameters that can be used in our computation:
Cost of rents:
Charging a rental fee plus an hourly rate.
Using the above as a guide, we have the following:
Initial rental fee = r
Hourly rate = x
The cost for h hours can then be represented as
C(h) = Initial rental fee + Hourly rate * Number of hours
Substitute the known values in the above equation, so, we have the following representation
C(h) = r + x * h
Evaluate
C(h) = r + xh

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

How do you change the base of an exponential function?
To change the base of an exponential function, we can use the formula:
log_b(a) = log_c(a) / log_c(b).
To change the base of an exponential function, you can use the property that logarithms with different bases are related by the following equation:
log_b(a) = log_e(a) / log_e(b)
Where log_b(a) is the logarithm of a to the base b and log_c(a) is the logarithm of a to the base e.
For example: To change log_3(7) to log_e(x)/log_e(y), we can use the property that logarithms with different bases are related by the following equation:
logb(a) = logc(a) / logc(b)
So log_3(7) = log_e(7) / log_e(3)
To find x and y we can use the logarithm properties and the definition of logarithm:
log_e(x) = log_e(7)
x = 7
log_e(y) = log_e(3)

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]

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).
