Answer:

7 degrees

Step-by-step explanation:

Start with the temperature of -7 deg at 6:00 a.m.

The temperature increases 14 degrees in the next 6 hours.

6 hours after 6:00 a.m. is noon.

We are asked the temperature at noon.

At noon, the temperature is 14 degrees higher than -7 deg.

We add the increase, 14 deg, to the starting temperature, -7 deg.

-7 deg + 14 deg = 7 deg

Answer: 7 degrees

The ocean freight charges for the given shipment in Canadian dollars would be approximately 603.25 CAD.

To calculate the ocean freight charges in Canadian dollars for the given shipment, we need to follow these steps:

Step 1: Calculate the volume and weight of each cargo item:

For the skids of Apple:

Volume = 100 cm x 100 cm x 150 cm

= 1,500,000 cm³

= 1.5 m³

Weight = 400 kg each x 2

= 800 kg

For the boxes of Orange:

Volume = 35" x 25" x 30"

= 26,250 cubic inches

= 0.4292 m³

Weight = 100 kg each x 3

= 300 kg

Step 2: Calculate the total volume and weight of the shipment:

Total Volume = Volume of Apples + Volume of Oranges

= 1.5 m³ + 0.4292 m³

= 1.9292 m³

Total Weight = Weight of Apples + Weight of Oranges

= 800 kg + 300 kg

= 1,100 kg

Step 3: Convert the ocean freight rate to Canadian dollars:

Ocean freight rate to Mumbai = $250 USD / m³

Conversion rate: 1 USD = 1.25 CAD (Canadian dollars)

Freight rate in CAD = $250 USD/m³ x 1.25 CAD/USD

= 312.5 CAD/m³

Step 4: Calculate the freight charges for the shipment:

Freight charges = Total Volume x Freight rate in CAD

Freight charges = 1.9292 m³ x 312.5 CAD/m³

= 603.25 CAD

The measure of the angle m∠STU is 42 degrees

Find the diagram to the image attached below:

Since the side RS = RU, this shows that:

m∠RTS = m∠RTU

Given the following parameters

m∠RTS = 5w - 69°

m∠RTU = w + 3°

Equating both expressions

5w - 69° = w + 3

5w - w = 3 + 69

4w = 72

w = 72/4

w = 18

Get the measure of m∠STU

m∠STU = m∠RTS + m∠RTU

m∠STU = 5w - 69 + w + 3

m∠STU = 6w - 66

m∠STU = 6(18) - 66

m∠STU = 42 degrees

Hence the measure of the angle m∠STU is 42 degrees

Answer:

62

If a biologist measures the offspring of the surviving finches and finds that their mean beak depth is 13 mm, the heritability (h2) of beak depth, to two decimal places is -0.33.

The heritability of a trait refers to the proportion of the variation in that trait within a population that can be attributed to genetic factors. In this case, the heritability of beak depth can be estimated using the following formula:

h2 = (response to selection) / (selection differential)

where the response to selection is the difference between the mean value of the trait in the next generation and the mean value in the current generation.

The selection differential is the difference between the mean value of the trait in the current generation of individuals that survive and reproduce and the mean value in the entire population.

Using the given data, the response to selection is 13 - 12 = 1 mm, and the selection differential is 12 - 15 = -3 mm. Therefore, the heritability of beak depth can be calculated as:

h2 = (1/-3) = -0.33

The negative value obtained here suggests that there may have been some measurement error or other factors influencing the results. It is important to note that heritability estimates are subject to various assumptions and limitations and should be interpreted with caution.

(a) False; A subspace is formed by the set of vectors that do not belong to the column space.

(b) True; If the matrix contains solely the zero vector, then it is the zero matrix.

(c) True; The column space of a particular matrix is equivalent to the column space of another specified matrix.

(d) False; The column space of one matrix is identical to the column space of another matrix.

(a) False; if A = [1 0; 0 0], then the column space of A is { e1 }, where e1 is the standard unit vector in the plane. If v is not in the column space of A, but w is not in the column space of A, then v + w is not in the column space of A.

Therefore, the set of vectors that are not in the column space of A does not form a subspace.

(b) True; if every vector in Rn is in the null space of A, then in particular, every standard unit vector is in the null space of A. Thus, the ith column of A is zero for i = 1, . . . , n, so A is the zero matrix.

(c) True; the column space of A is generated by the columns of A, while the column space of AB is generated by linear combinations of the columns of AB. By definition of matrix multiplication, the columns of AB are linear combinations of the columns of A, so the column space of AB is a subspace of the column space of A. Conversely, let b be in the column space of A. Then there is an x in Rm such that Ax = b. Thus, ABx = A(Bx), so b is in the column space of AB. Therefore, the column space of A is a subspace of the column space of AB. Hence the two column spaces are equal.

(d) False; if A = [1 0; 0 0] and B = [0 0; 0 1], then the column space of A is { e1 }, while the column space of B is { e2 }. The column space of AB is { 0 }, so it is not equal to either column space.

Infinitely many solutions.

You basically have just one equation.

The top equation is the bottom equation times 5.

Step-by-step explanation:

Answer: C. Infinite many solution

Step-by-step explanation:

since the GCF in it is 5, we factor out 5

                   4x-y=1

#2 compare the first and the second equation

                     \(\left \{ {{4x-y=1} \atop {4x-y=1}} \right.\)

Given f(x, y, z) = 2xyz, and function f(x) g(x, y, z) = 3x^2 + 3yz + xy = 27. To find the critical point which satisfies the condition of Lagrange Multipliers

we need to use the method of Lagrange multipliers as follows.  Let's define λ as the Lagrange Multiplier and write the Lagrangian L as:L = f(x, y, z) - λg(x, y, z)Now, substitute the given functions to the above equation.L = 2xyz - λ(3x^2 + 3yz + xy - 27)Taking the partial derivative of L with respect to x and equating it to zero, we get0 = ∂L/∂x = 2yz - 6λx + λyUsing the same method, we get0 = ∂L/∂y = 2xz - 3λz + λx0 = ∂L/∂z = 2xy - 3λyThe given function is such that it becomes more complicated to find x, y, and z using the partial derivative method since they are very mixed up. Thus, we have to use other methods such as substitution method or solving the system of equations. So, we need to solve the system of equations:2yz = 6λx - λy2xz = 3λz - λx2xy = 3λyTo do this, we need to eliminate the λ's. Dividing the first equation by 6 and then substituting λy for z in the second equation, we get:y = 4x/3Substituting this into the third equation and solving for λx, we get:λx = 8/3Substituting these values for x and λx into the first equation, we get:2yz = 8y/3So, z = 4/3Substituting these values into the second equation, we get:2x * (4/3) = 3λz - λx8x/3 = 12λ/3λ = 2/3So, x = 1 and y = 4/3.Thus, the critical point is (x, y, z) = (1, 4/3, 4/3).

The sum of the infinite geometric series –288 –216 –144 –72 is -1152.

The sum of an infinite number of terms having a constant ratio between successive terms is called as infinite geometric series.

Given series, -288, -216, -144, -72, ...

The sum of the infinite geometric series can be calculated as:

Sum = \(\dfrac{a}{1 -r}\)

Here, 'a' is the first term of the series and 'r' is the common ratio.

a = -288

The common difference can be calculated as:

r = \(\dfrac{(-216)}{(-288)}\)

= \(\dfrac{3}{4}\)

Substitute the values in the sum formula:

Sum = \(\dfrac{-288}{1 - \dfrac{3}{4}}\)

It can be simplified as:

Sum =  -288 \(\times\) 4

The

dimensions

of the lid that will sit exactly on the sides of the plywood box would be: Width = W + 0.2 cm = 5.2n + 0.2 cm., Length = L + 0.2 cm = 5.2m + 0.2 cm.These dimensions ensure that the lid will cover the entire box, including the plywood separators and the cans, sitting flush with the sides of the box.

To determine the dimensions of the lid that will sit exactly on the sides of the plywood box containing the canned tomatoes, we need to calculate the total width and length of the box.

Each can has a

diameter

of 5 cm, so the radius of each can is half of the diameter, which is 2.5 cm. The height of each can is twice its diameter, which is 10 cm.

When the cans touch the sides of the plywood box, the distance from the center of one can to the center of the next can, including the thickness of the plywood separator, is equal to the sum of the radius of one can, the

radius

of the other can, and the thickness of the plywood separator.

Therefore, the distance between the centers of two adjacent cans is:

2.5 cm + 2.5 cm + 0.2 cm = 5.2 cm.

Since the cans just touch the sides of the plywood box, the width and length of the box must be an integer multiple of the distance between the centers of the cans.

Assuming the width and length of the box are represented by W and L respectively, we have the following equations:

W = 5.2n, where n is a

positive integer

representing the number of cans in one row.

L = 5.2m, where m is a positive integer representing the number of cans in one column.

To cover the box with a lid that sits exactly on its sides, the lid's dimensions should be equal to the width and length of the box, taking into account the thickness of the plywood separators.

The width of the lid would be: W + 0.2 cm.

The length of the lid would be: L + 0.2 cm.

The zeros of the function are x=1 and x=3, and the minimum value of the function is at x=2.

What is the polynomial function?

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.

To find the zeros, we set the function equal to zero and solve for x:

(2x-2)(x-3) = 0

This equation is true when either 2x-2=0 or x-3=0. Solving for x in each case, we get:

2x-2=0  =>  x=1

x-3=0  =>   x=3

So the zeros of the function are x=1 and x=3.

To find the maximum or minimum value of the function, we can take the derivative of the function and set it equal to zero:

f'(x) = 4x - 8

4x - 8 = 0  ---->  x = 2

So the critical point of the function is x=2. To determine if this point is maximum or minimum, we can use the second derivative test:

f''(x) = 4

Since f''(2) > 0, the function has a minimum at x=2.

Therefore, the zeros of the function are x=1 and x=3, and the minimum value of the function is at x=2.
