Answer: If the transformation of the parent function f(x) = √x is a reflection over the x-axis, it means that the graph of the transformed function g(x) is obtained by reflecting the graph of f(x) over the x-axis.

The reflection of the function f(x) over the x-axis is obtained by negating its output, so the function g(x) can be written as:

g(x) = -√x

So the transformed function g(x) is a reflection of the parent function f(x) = √x over the x-axis.

The statement "sum of a and b integers is a negative integer" is true given that A and B are both negative integers and A is greater than B.

When we add two negative integers, the sum is always negative. This is because adding a negative number is the same as subtracting its absolute value. Therefore, if A and B are negative integers, then A + B will be negative as well.

Since A > B, the sum A + B will be closer in value to A than to B. However, it will still be negative because A and B are both negative integers.

So, the sum of A and B is a negative integer, and the statement is true.

In stabilizing selection, option (d) The intermediate phenotype becomes rare.

Stabilizing selection occurs when individuals with extreme phenotypes are at a disadvantage, and individuals with intermediate phenotypes have a greater chance of survival and reproduction.

This means that over time, the population shifts towards the intermediate phenotype. Let's take an example to explain this concept.

Suppose we have a population of rabbits with different fur colors, ranging from white to dark brown. Predators are more likely to spot white rabbits in a snowy environment, while brown rabbits are more likely to be seen in a forest environment. This means that the extreme phenotypes (white and dark brown) are at a disadvantage, while the intermediate phenotype (light brown) is more likely to survive and reproduce. Over time, the population will shift towards the light brown phenotype, as it is the most advantageous trait.

In conclusion, stabilizing selection is a mechanism of natural selection that promotes the preservation of the average characteristics of a population. It occurs when individuals with intermediate phenotypes have a higher chance of survival and reproduction, leading to the shift of the population towards the intermediate phenotype. Mathematically, we can represent this concept using the mean and standard deviation of a population.

The square root of 378 is 19.4422

The square root of a number is a value that, when multiplied by itself, gives the original number. The symbol used to denote the square root is √, and it is placed in front of the number for which we are looking for the square root.

First, let's define what factorial means. The factorial of a non-negative integer is the product of all positive integers less than or equal to that number.

Next, we have to compute the square root of 378, which is a much simpler task. The square root of a number is a value that, when multiplied by itself, gives the original number.

The double-angle identity for cosine is cos(2x) = cos²(x) - sin²(x).

To derive the reduction identities, we can use this double-angle identity and manipulate it to express cosine or sine of x in terms of cosine or sine of a smaller angle. Here are the steps for deriving the reduction identity for cosine: Start with the double-angle identity: cos(2x) = cos²(x) - sin²(x).

Divide both sides by cos²(x): cos(2x) / cos²(x) = (cos²(x) - sin²(x)) / cos²(x).

Use the identity sin²(x) + cos²(x) = 1 to replace cos²(x) in the denominator: cos(2x) / cos²(x) = (1 - sin²(x)) / cos²(x).

Rearrange the right-hand side: cos(2x) / cos²(x) = 1/cos²(x) - sin²(x) / cos²(x).

Recognize that 1/cos²(x) is equal to sec²(x), and use the identity tan²(x) + 1 = sec²(x) to replace it: cos(2x) / cos²(x) = sec²(x) - tan²(x).

Simplify using the identity cos(x)/sin(x) = cot(x): cos(2x) / cos²(x) = cosec²(x) - cot²(x).

Simplify the left-hand side using the identity cos(2x) = 2cos²(x) - 1: (2cos²(x) - 1) / cos²(x) = cosec²(x) - cot²(x).

Rearrange and simplify: 2 - (1/cos²(x)) = cosec²(x) - cot²(x).

Recognize that 1/cos²(x) is equal to sec²(x) and cosec(x) is equal to 1/sin(x): 2 - sec²(x) = 1/sin²(x) - cot²(x).

Simplify the left-hand side using the identity 1 - sin²(x) = cos²(x): cos²(x) - sec²(x) = 1/sin²(x) - cot²(x).

Recognize that sec(x) is equal to 1/cos(x) and cot(x) is equal to cos(x)/sin(x): cos²(x) - 1/cos²(x) = sin²(x)/cos²²(x) - cos²x)/sin²(x).

Simplify: cos⁴(x) - 1 = sin²(x) - cos⁴(x).

Rearrange: 2cos⁴(x) = sin²(x) + 1.

Finally, recognize that sin²(x) + cos²(x) = 1, and use it to replace sin²(x): 2cos⁴(x) = cos²(x). This is the reduction identity for cosine: cos²(x/2) = (1 + cos(x))/2.

To derive the reduction identity for sine, we can use the same double-angle identity for cosine and manipulate it to express sine of x in terms of sine or cosine of a smaller angle. The steps are similar but may require using different.

The actual dimensions of the figure is 3.9 x 2.1

Scale factor is a mathematical term, which we use to scale 2-dimensional and 3-dimensional shapes. Scale factor is a measure of similar figures. Those figures who look the same but are in different sizes.

For example, Two spheres look similar but could have different radii.

For the first dimension of 7.8 cm, we can set up a proportion using the scale factor:

2 cm : 1 m = 7.8 cm : x

where x is the actual length we want to find.

Solving for x, we get:

x = (7.8 cm x 1 m) / 2 cm

x = 3.9 m

Therefore, the first actual dimension is 3.9 meters.

For the second dimension of 4.2 cm, we can use the same method:

2 cm : 1 m = 4.2 cm : y

where y is the actual width we want to find. Solving for y, we get:

y = (4.2 cm x 1 m) / 2 cm

y = 2.1 m

Therefore, the second actual dimension is 2.1 meters.

So the actual dimensions of the figure are 3.9 meters by 2.1 meters.

First things first, we are rotating about a point so the first we do is the move the clockwise rotation to the origin.

Since a rotation is a rigid transformation, we must move all the other points as well.

So move every point using the rotation vector

R(-6,-8), move every point to

D(1-6,4-8)=D'(-5,-4)

E(5-6,5-8)=E'(-3,-5)

F(4-6,1-8)=F'(-2,-7)

G(0-6,0-8)=G'(-6,-8)

So know since the center of rotation is middle at (0,0) , we can apply the rotation rules

For a 270 clockwise rotation, we apply this rule

(-y,x)

So for the points we know get

D''(5,-4)

E''(3,-5)

F''(2,-7)

G"(6,-8)

Know since we done our rotation, we undo what we did in step 1, we add 6 to the x coordinates and 8nto the y coordinate

D"'(11,8)

E"'(9, 3)

F"(8,1)

G"'(12,0)

87654321

Step-by-step explanation:

Answer:

Step-by-step explanation:

The interest rate of 1.25% compounded monthly means that the interest earned each month is 1.25% of the current balance. Here's how you can calculate the final balance in the account after 20 years:

First, calculate the interest earned each month: $200 * 1.25% = $2.50

Then, add the interest earned to the monthly deposit to get the new balance: $200 + $2.50 = $202.50

Repeat this process for 240 months (20 years x 12 months/year).

The final balance in the account after 20 years would be approximately $71,934.24.

To find the total money you will put into the account, simply multiply the monthly deposit by the number of months: $200 * 240 = $48,000.

To find the total interest earned, subtract the initial deposit from the final balance: $71,934.24 - $48,000 = $23,934.24

So, in 20 years, you will have put a total of $48,000 into the account, and you will have earned a total of $23,934.24 in interest.
