I hope this helps! :>
The height of the tallest model is 81 cm and the model is [tex]y ( x ) = 3^x[/tex].
Given data:
Let x be the height of the tallest model.
According to the information given, the height of each model is three times the height of the previous model.
So, represent the heights of the models as and exponential model where [tex]y ( x ) = 3^x[/tex].
1st model: 3 centimeters (3 cm)
2nd model: 3 times the height of the 1st model = 3 * 3 cm = 9 centimeters (9 cm)
3rd model: 3 times the height of the 2nd model = 3 * 9 cm = 27 centimeters (27 cm)
4th model: 3 times the height of the 3rd model = 3 * 27 cm = 81 centimeters (81 cm)
So, the height of the tallest model can be represented as:
x = 81 centimeters
Hence, the height of the tallest model is 81 centimeters.

The high school's lunch menu repeats every 6 school days. The middle school lunch menu repeats every 8 school days. On March 5th, both schools served chicken wraps. What is the next calendar date on which both schools will serve chicken wraps?
Answers
Final answer:
Both schools will serve chicken wraps again on March 29th.
Explanation:
The question involves finding the next calendar date when both the high school and middle school will serve chicken wraps again. To solve this problem, we need to find the Least Common Multiple (LCM) of the two repeating cycles, which are 6 days for the high school and 8 days for the middle school.
First, let's calculate the LCM of 6 and 8:
Multiple of 6: 6, 12, 18, 24, 30, 36, 42, 48, ...Multiple of 8: 8, 16, 24, 32, 40, 48, ...We find that the smallest common multiple is 24 days.
Since both schools served chicken wraps on March 5th, we simply add 24 days to that date. This gives us:
March 5th + 24 days = March 29thTherefore, both schools will serve chicken wraps again on March 29th.

For the straight line defined by the points (3, 59) and (5, 87), determine the slope and y-intercept. do not round the answers.
Answers
slope = (87 - 59) / (5 - 3) = 28/2 = 14 <== ur slope
y = mx + b
slope(m) = 14
use either of ur points...(3,59)...x = 3 and y = 59
now we sub and find b, the y int
59 = 14(3) + b
59 = 42 + b
59 - 42 = b
17 = b <=== ur y int (0,17)
The slope of the given line is 14 and y intercept is 17.
What is the equation of a line ?The equation of a line is y = mx + b.Where m is slope and b is y intercept.
According to the given question a straight line defined by the points (3, 59) and (5, 87).
We know slope (m) = (y₂ -y₁)/(x₂ - x₁)
∴ m = (87 - 59)/(5 - 3)
m = 28/2
m = 14.
Now the equation of the line will be of the form y = 14x + b.

60÷5(7-5)=24 is that correct ? Thanks
Answers
Absolutely, it is correct.
[tex]\boxed{ \ 60 \div 5 (7 - 5) = 24 \ }[/tex]
Further explanationIn the 1500s the specific rules of the order of operation were promptly issued. The order of these workings states which processes take precedence (as a key priority) before which other operations.
Operation priorities are as follows.
Brackets (simplify in it)ExponentMultiplication or Division (from left to right)Addition or Subtraction (from left to right)Let's implement the rule.
[tex]\boxed{ \ 60 \div 5 (7 - 5) = \ ? \ }[/tex]
Subtract 7 by 5 in parentheses.
[tex]\boxed{ \ 60 \div 5 (2) = \ ? \ }[/tex]
Properly apply rule number 3 from the priority operation above. Initially, we have to divide 60 by 5.
[tex]\boxed{ \ 12(2) = \ ? \ }[/tex]
Continuing with multiplication 12 by 2 proves the exact result.
[tex]\boxed{ \ 12 \times 2 = 24 \ }[/tex]
Thus, this equation is correct.
[tex]\boxed{ \ 60 \div 5 (7 - 5) = 24 \ }[/tex]
Note:
What is the result if we don't follow operation priorities? Let's see.
At this crucial point.
[tex]\boxed{ \ 60 \div 5 (2) = \ ? \ }[/tex]
We decide to multiply 5 by 2, even though there are no parentheses from them, only parentheses for 2.
[tex]\boxed{ \ 60 \div 5 \times 2 = \ ? \ }[/tex]
[tex]\boxed{ \ 60 \div 10 = 6 \ }[/tex]
[tex]\boxed{ \ 60 \div 5 (7 - 5) = 6 \ }[/tex]
That's what happens if we don't follow operating priorities.
Unless the problem like this:
[tex]\boxed{ \ 60 \div (5 (7 - 5)) = 6 \ }[/tex]
[tex]\boxed{ \ 60 \div (5 (2)) = 6 \ }[/tex]
[tex]\boxed{ \ 60 \div 10 = 6 \ }[/tex]
Thus, the difference must be considered. Consequently, follow the priority of the operation and look at the problem in detail.

A completely filled 20 gallon tank originally contains 10 pounds of salt dissolved in water. pure water enters the tank at the rate of 5 gallons/minute, and the well-stirred mixture leaves the tank at the same rate. find the amount of salt in the tank at any time t .
Answers
To find the amount of salt in the tank at any time t, we can use the equation S(t) = 10 - 10(W(t)/20), where W(t) represents the amount of water in the tank at time t. Substituting the given values, we can calculate the amount of salt in the tank.
Explanation:To find the amount of salt in the tank at any time t, we need to consider the rate at which pure water enters and leaves the tank. Since water enters the tank at a rate of 5 gallons/minute, the amount of water in the tank at any time t can be represented by the equation: W(t) = 5t, where t represents time in minutes. The concentration of salt in the tank remains constant, so the amount of salt in the tank at any time t can be represented by the equation: S(t) = 10 - 10(W(t)/20), where S(t) represents the amount of salt in pounds and W(t) represents the amount of water in gallons.
Let's solve for S(t) when t = 10 minutes:
S(10) = 10 - 10(5/20) = 10 - 10(1/4) = 10 - 10/4 = 10 - 2.5 = 7.5 pounds of salt.

solve the following formula for x
y=2mx+9b
Answers
To solve the equation y = 2mx + 9b for x, subtract 9b from both sides, and then divide by 2m. The result is x = (y - 9b) / (2m). This manipulation is emblematic of solving linear equations which are foundational in algebra.
The student is asking to solve the linear equation y = 2mx + 9b for the variable x. This type of problem involves algebraic manipulation to isolate the variable of interest. Here are the steps to solve for x:
Subtract 9b from both sides of the equation: y - 9b = 2mx.Divide both sides by 2m to solve for x: x = (y - 9b) / (2m).In this case, y is the dependent variable, m is the slope of the line, and b would be the y-intercept if this equation were graphed on a coordinate plane. To better understand this concept, let's take the specific equation y = 9 + 3x as an example which is a linear equation with b set to 9 and m set to 3.
To visualize this equation, one can construct a table of values by selecting various x values and calculating the corresponding y values. Then, these points are plotted on a graph to show the linear relationship. This process is depicted in Table A1 and Figure A1, with the equation illustrated in a graph.
The general form of a linear equation is y = mx + b, where m represents the slope and b the y-intercept. In these exercises, understanding and manipulating this form helps us find relationships between variables and understand how changes in one variable affect another.

Step-by-step explanation:
From the intersecting chords theorem we know that if two chords are intersecting each other in a circle then the products of the lengths of the line segments of each chord are equal.
Therefore AY.YC =YB.YD
Here AY = x, BY = 3, YC = 6, YD = 8

Graph the function -2x+5y=10
Answers
the reason we call it linear, is that all solutions (x, y) to this equation, when plotted in the x-y axis, form a line.
To draw this line, 2 points are enough, that is 2 solutions (x, y) of the equation.
-------------------------------------------------------------------------------------------------
-2x+5y-10=0 is a linear equation (a=-2, b=5, c=-10)
to find 2 solutions, we set x or y any value we want, and solve for the other
for example:
let x=0,
then
-2x+5y-10=0 becomes 5y-10=0, so y=2
this gives us the solution (0, 2)
another example; set y=0
then -2x+5y-10=0 becomes -2x-10=0; -2x=10 so x=-5
thus another solution is (-5, 0)
Draw these 2 points, and join them with a line, as shown in the figure.
