Which describes the role of oxygen in photosynthesis? A. It is a reactant, so it is released by the plant. B. It is a product, so it is released by the plant. C. It is a reactant so it enters the plant. D. It is a product, so it enters the plant.
Answer:
B) It is a product, so it is released by the plant.
Step-by-step explanation:
- Plants release oxygen for humans and humans give carbon dioxide to plants.
- The role of oxygen in photosynthesis is a waste product.
Answer: The oxygen gas is a product, so it is released by the plant.
Explanation:
Photosynthesis is defined as the process by which the producers make glucose with the help of carbon dioxide and water in the presence of sunlight.
The chemical equation representing this reaction follows:
In the above reaction, oxygen gas is written on the product side. So, it is formed by the plant and is released.
Hence, the oxygen gas is a product, so it is released by the plan.
A rocket rises at 5 ft/s between 0 and 10 seconds. Afterwards it rises at 15 ft/s for another 15 seconds. Use one loop to calculate the rockets height at the end of the 25 seconds. Use h as the variable for height.
The height of the rocket at the end of the 25 seconds is 275 ft.
We have given that,
a rocket rises at 5 ft/s between 0 and 10 seconds,
therefore
V₁ = 5 ft/s
T₁ = 10 seconds
Height in first 10 seconds = ?
we know the formula to find the height,
i.e Height = velocity × time
⇒ H₁ = V₁ × T₁
= 5 × 10
H₁ = 50 ft
Therefore height of the rocket in the first 10 seconds is 50 ft.
Now it given that, rocket rises at 25 ft/s for another 15 seconds.
i.e V₂ = 15 ft/s
T₂ = 15 seconds
H₂ = ?
H₂ = V₂ × T₂
= 15 × 15
H₂ = 225 ft
Therefore height of the rocket in next 15 seconds is 225 ft.
Now we will find the height of the rocket at the end of the 25 seconds.
i.e H = H₁ + H₂
= 50 + 225
H = 275 ft
Hence the height of the rocket at the end of 25 seconds is 275 ft.

please help, Find the solution to the given inequality and pick the correct graphical representation
Using the answers possible, you could pick x=0 and see if 0 work.
-3 + | 0-2 | > 5
-3 + | -2 | > 5
-3 + 2 > 5
-1 > 5
this is false, so any answer that includes 0 is not correct
this eliminates "-6 < x < 10" and "x > -6 or x < 10" since they both include 0.
that leaves only "x < -6 or x > 10".
And the graph that matches this answer is the very bottom graph with two open circles at -6 and 10 and arrows pointing outward.
Now if you want to solve the inequality, that'd look like this:
-3 + | x - 2 | > 5
| x - 2 | > 8 by adding 3 to both sides
this will split into "x - 2 > 8 or x - 2 < -8"
Solving each of those, you'd have "x > 10 or x < -6" which is the answer we previously determined.

Consider the following IS-LM model: C=217+0.51Y D I=156+0.16Y−1,038i G=254 T=203 i=0.04 The IS equation is determined to be Y=1,586.27−3,145.45. The LM equation is given as i=0.04. Using the IS and LM equations, the equilibrium real output, Y, is (Round your response to the nearest integer.) Using the IS-LM model, the equilibrium value of consumption, C, is (Round your response to the nearest integer.)
In the given IS-LM model, the equilibrium real output, Y, and the equilibrium value of consumption, C, can be determined using the IS and LM equations. The IS equation relates output to the interest rate, while the LM equation represents the equilibrium condition in the money market. By substituting the given values into the equations, we can find the equilibrium values.
The IS equation is given by: Y = 1,586.27 - 3,145.45i.
The LM equation is given as: i = 0.04.
To find the equilibrium real output, we substitute the value of i from the LM equation into the IS equation:
Y = 1,586.27 - 3,145.45 * 0.04.
Calculating the right side of the equation, we have:
Y = 1,586.27 - 125.82,
Y ≈ 1,460.
Therefore, the equilibrium real output, Y, is approximately 1,460.
To find the equilibrium value of consumption, we substitute the equilibrium real output, Y, into the consumption function:
C = 217 + 0.51Y.
Substituting Y = 1,460, we have:
C = 217 + 0.51 * 1,460.
Calculating the right side of the equation, we find:

A cantilevered beam is subjected to uniform pressure on the top surface as shown in the figure below. E = 29.5×106 psi, ν = 0.31, thickness = 1 inch, P = 25 psi.
(a) If L = 40 inch, h = 4 inch (slender beam), find the maximum normal stress σx on the support and the displacements at the center of the free end (use slender beam theory).
(b) If L = 10 inch, h = 4 inch (deep beam), find the maximum normal stress σx on the support and the displacements at the center of the free end
a) The maximum normal stress is -50 psi and displacement is -0.090 inch. b) The maximum normal stress is -50 psi and displacement is -0.023 inch.
To solve this problem, we'll use the slender beam theory. The slender beam theory assumes that the beam is long and slender, meaning its length is much greater than its thickness. Let's solve the problem step by step.
(a) Slender Beam (L = 40 inch, h = 4 inch)
Step 1: Calculate the maximum normal stress on the support (σx).
The formula for the maximum normal stress on the support of a cantilevered beam under uniform pressure is given by:
σx = -0.5 * P * h / t
where P is the pressure, h is the height of the beam, and t is the thickness of the beam.
Substituting the given values:
P = 25 psi
h = 4 inch
t = 1 inch
σx = -0.5 * 25 * 4 / 1
= -50 psi
The negative sign indicates that the stress is compressive.
Therefore, the maximum normal stress on the support is -50 psi.
Step 2: Calculate the displacement at the center of the free end.
The formula for the displacement at the center of the free end of a cantilevered beam under uniform pressure is given by:
δ = -P * \(L^{3}\) / (3 * E * t * \(h^{2}\))
where δ is the displacement, P is the pressure, L is the length of the beam, E is the elastic modulus of the material, t is the thickness of the beam, and h is the height of the beam.
Substituting the given values:
P = 25 psi
L = 40 inch
E = 29.5×\(10^{6}\) psi
t = 1 inch
h = 4 inch
δ = -25 * \(40^{3}\) / (3 * 29.5×\(10^{6}\) * 1 * \(4^{2}\))
≈ -0.090 inch
Therefore, the displacement at the center of the free end is approximately -0.090 inch.
(b) Deep Beam (L = 10 inch, h = 4 inch)
Step 1: Calculate the maximum normal stress on the support (σx).
Using the same formula as in the previous step:
σx = -0.5 * P * h / t
Substituting the given values:
P = 25 psi
h = 4 inch
t = 1 inch
σx = -0.5 * 25 * 4 / 1
= -50 psi
The negative sign indicates that the stress is compressive.
Therefore, the maximum normal stress on the support is -50 psi.
Step 2: Calculate the displacement at the center of the free end.
Using the same formula as in the previous step:
δ = -P * \(L^{3}\) / (3 * E * t * \(h^{2}\))
Substituting the given values:
P = 25 psi
L = 10 inch
E = 29.5×\(10^{6}\) psi
t = 1 inch
h = 4 inch
δ = -25 * \(10^{3}\) / (3 * 29.5×\(10^{6}\) * 1 * \(4^{2}\))
≈ -0.023 inch
Therefore, the displacement at the center of the free end is approximately -0.023 inch.

If $3200 is deposited into a savings account with a 3. 5% interest rate, compounded quarterly, what will be the value of the account after 15 years?
The value of the account after 15 years will be approximately $5,756.24.
What is the future value of a savings account after 15 years with a $3,200 deposit and a 3.5% interest rate compounded quarterly?To calculate the future value of the savings account, we use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the future value, P is the principal (initial deposit), r is the interest rate (expressed as a decimal), n is the number of compounding periods per year, and t is the number of years. In this case, the deposit is $3,200, the interest rate is 3.5% (or 0.035), and compounding is done quarterly (n = 4). Substituting these values into the formula with t = 15 years, we can calculate the future value. Therefore, the value of the account after 15 years will be approximately $5,756.24.

A group of 12 students take both the SAT Math and the SAT Verbal. The least-squares regression line for predicting Verbal score from Math score is determined to be: Verbal
The least-squares regression line is used to predict the values of one variable based on the values of the other variable. In this case, the Verbal score can be predicted from the Math score.
The formula for the least-squares regression line is: Verbal = a + b * Math, where a is the intercept and b is the slope. The least-squares regression line for predicting Verbal score from Math score can be determined using a calculator or a statistical software package.
Once the least-squares regression line has been determined, it can be used to make predictions about the Verbal score for a given Math score. For example, if a student scores 600 on the Math portion of the SAT, the least-squares regression line can be used to predict their Verbal score.
The least-squares regression line is a useful tool for analyzing the relationship between two variables. It can be used to identify patterns and trends, and to make predictions about future values.
However, it is important to remember that correlation does not equal causation, and that other factors may be influencing the relationship between the two variables. The least-squares regression line should be used as a starting point for further analysis, rather than as a definitive answer.

How do you know if a question is permutation or combination?
It is a permutation. If the order of the items does not matter, it is a combination.
Permutation and combination are two types of mathematical concepts that are used to determine the number of ways to arrange a set of items. The main difference between permutation and combination is the order of the items.
A permutation is an arrangement of objects in a specific order. It means that the order of the items matters. For example, if we have three items, A, B, and C, the permutations of these items are ABC, ACB, BAC, BCA, CAB, and CBA.
A combination is a selection of items without regard to the order. It means that the order of the items does not matter. For example, if we have three items, A, B, and C, the combinations of these items are AB, AC, BC, and BA, CA, CB.

Step-by-step explanation:
First we can see that 1200 is 12 times 100. We can confirm this by doing 1200/100 =12. Then we see that 58 students out of each 100 like art over music. So we can do 58*12= 696 because we are just multiplying the ratio of 1:12 to 58:696
