miriam is studying a type of plant that grows at a constant rate. Every month, she visits two of these plants and measures their heights. she made this table. Miriam want an equation she can use to find Plant A’s height in centimeters (a) given Plant AB’s height in centimeters (b).
The equation that represents the situation is a = b- 4.
Since the plant grows at a constant rate, we can assume that the height of the plant is increasing linearly with time.
Let's use the data from Week 1 and Week 2 to find the rate of growth for each plant:
For Plant A: Growth rate = (24 cm - 22 cm) / (2 weeks - 1 week) = 2 cm/week
For Plant B: Growth rate = (28 cm - 26 cm) / (2 weeks - 1 week) = 2 cm/week
Since the growth rate is constant, we can use the equation of a line to model the height of each plant over time:
For Plant A: a = 2t + b, where t is the time in weeks and b is the initial height of the plant.
For Plant B: b = 2t + c, where c is the initial height of Plant B.
We can find the values of b and c by substituting the data from Week 1 into these equations:
For Plant A: 22 = 2(1) + b, so b = 20.
For Plant B: 26 = 2(1) + c, so c = 24.
Now we can substitute these values into the equations for Plant A and Plant B:
Plant A: a = 2t + 20
Plant B: b = 2t + 24
To find an equation that gives Plant A's height in terms of Plant B's height, we can solve the equation for t in terms of b:
b = 2t + 24
2t = b - 24
t = (b - 24) / 2
Then we can substitute this expression for t into the equation for Plant A:
a = 2t + 20
a = 2[(b - 24) / 2] + 20
a = b - 24 + 20
a = b - 4
So the equation we were looking for is:
a = b - 4
Therefore, to find Plant A's height in centimeters given Plant B's height in centimeters, we simply subtract 4 from Plant B's height.

When six times the larger of two numbers is added to seven times the smaller, the result is 114. Ten times the larger less nine times the smaller is 66. Determine the numbers.
Answer:
Step-by-step explanation:
Let the larger number = x
Smaller number = y
6x + 7y = 114 ------------(I)
10x - 9y = 66 ------------(II)
Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x
(1)*9 54x + 63y = 1026
(II)*7 70x - 63y = 462 {Now add}
124x = 1488 {Divide both sides by 124}
x = 1488/124
x = 12
Plugin x = 12 in any of the equation. Here, We are substituting in equation (I)
6*12 + 7y = 114
72 + 7y =114
7y = 114 - 72
7y = 42
y = 42/7
y = 6
The numbers are 12 , 6

The equations of the composite functions are (h o h)(x) = (x² + 3)² + 3 and (f o f)(x) = x
How to calculate the composite functionsFrom the question, we have the following equations that can be used in our computation:
h(x) = x² + 3
f(x) = 3/4x
From the above, we have
(h o h)(x) = h(h(x))
So, we have
(h o h)(x) = (x² + 3)² + 3
Also, we have
(f o f)(x) = 3/[4(3/4x)]
Evaluate
(f o f)(x) = x
Hence, the composite functions are (h o h)(x) = (x² + 3)² + 3 and (f o f)(x) = x

The distance that a freefalling body falls in each second starting with the first second is given by the arithmetic progression 16, 48,80,112
find the distance, the body falls in the seventh second
Answer:
208 units
Step-by-step explanation:
The first term is given as 16, which means a = 16.
The second term can be obtained by adding the common difference to the first term: 16 + d = 48.
The third term is obtained by adding the common difference to the second term: 48 + d = 80.
The fourth term is obtained by adding the common difference to the third term: 80 + d = 112.
We can solve these equations to find the value of 'd':
16 + d = 48
d = 48 - 16
d = 32
48 + d = 80
32 + 48 = 80 (valid)
80 + d = 112
32 + 80 = 112 (valid)
Therefore, the common difference is 32.
Now that we have the common difference, we can find the distance the body falls in the seventh second.
The formula for finding the nth term of an arithmetic progression is:
a_n = a + (n - 1) * d
where a_n is the nth term, a is the first term, n is the position of the term, and d is the common difference.
Plugging in the values, we can find the seventh term:
a_7 = 16 + (7 - 1) * 32
a_7 = 16 + 6 * 32
a_7 = 16 + 192
a_7 = 208
Therefore, the distance the body falls in the seventh second is 208 units.
Determine the turning points and distinguish between them when necessary y=x³ - 3x - 9x + 4
The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).
To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.
1. Find the derivative of the function:
y' = 3x² - 6x - 9
2. Set the derivative equal to zero and solve for x:
3x² - 6x - 9 = 0
3. Factorize the quadratic equation:
3(x² - 2x - 3) = 0
4. Solve the quadratic equation by factoring or using the quadratic formula:
(x - 3)(x + 1) = 0
This gives us two possible values for x: x = 3 and x = -1.
5. Substitute these critical points back into the original function to find the corresponding y-values:
For x = 3:
y = (3)³ - 3(3)² - 9(3) + 4
= 27 - 27 - 27 + 4
= -23
For x = -1:
y = (-1)³ - 3(-1)² - 9(-1) + 4
= -1 - 3 + 9 + 4
= 9
6. Therefore, the turning points are (3, -23) and (-1, 9).
Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

Use inductive reasoning to predict the most probable next number in the list.
3, 9, -3, 3, -9, -3, -15, -9, -21, ?
Need Help
Answer: -27
Step-by-step explanation: Use inductive reasoning to predict the most probable next number in the list.
3, 9, -3, 3, -9, -3, -15, -9, -21, ?
We can start by looking at the differences between consecutive terms in the list:
9 - 3 = 6 -3 - 9 = -12 3 - (-3) = 6 -9 - 3 = -12 -3 - (-9) = 6 -15 - (-3) = -12 -9 - (-15) = 6 -21 - (-9) = -12
Notice that the differences alternate between positive 6 and negative 12. This suggests that the pattern involves adding 6, then subtracting 12, and then adding 6 again. Applying this pattern to the last term in the list (-21), we get:
-21 + 6 = -15 -15 - 12 = -27 -27 + 6 = -21
Therefore, we predict that the most probable next number in the list is -27.

A tank in the shape of a hemisphere has a diameter of 24 feet. If the liquid that fills the tank has a density of 92.5 pounds per cubic foot, what is the total weight of the liquid in the tank, to the nearest full pound?
The total weight of the liquid in the tank is approximately 12,628 pounds.
To calculate the weight of the liquid, we need to determine the volume of the hemisphere and then multiply it by the density of the liquid. The formula for the volume of a hemisphere is V = (2/3)πr³, where r is the radius of the hemisphere.
In this case, the diameter of the tank is given as 24 feet, so the radius is half of that, which is 12 feet. Plugging this value into the formula, we get V = (2/3)π(12)³ ≈ 904.78 cubic feet.
Finally, we multiply the volume by the density of the liquid: 904.78 cubic feet * 92.5 pounds per cubic foot ≈ 12,628 pounds. Therefore, the total weight of the liquid in the tank is approximately 12,628 pounds.
In summary, to calculate the weight of the liquid in the tank, we first determine the volume of the hemisphere using the formula V = (2/3)πr³. Then, we multiply the volume by the density of the liquid.
By substituting the given diameter of 24 feet and using the appropriate conversions, we find that the total weight of the liquid is approximately 12,628 pounds.
