The rule of translation of LMN to L'M'N is: Shift right by 3 units and shift up by 1 unit.

What is a translation of triangles?

A translation of a triangle is a transformation in which a triangle is moved from one position to another, without changing its shape or size.

From the graph, we can see that LMN is translated to L'M'N'

The coordinates of L is:

L = (-6,-4)

The coordinates of L' is:

L' = (-3, 3)

Subtract L from L'

(x, y) = L'-L

(x, y) = (-3,-3)-(-6, -4)

(x, y) = (-3+6,-3+ 4)

x, y)= (3, 1)

Hence, The rule of translation of LMN to L'M'N is: Shift right by 3 units and shift up by 1 unit.

The initial cost of the car is 15,000 and the rate of depreciation is 0.77.

The initial cost, I, of the car is 15,000 and the rate of depreciation, r, is 0.77. This can be expressed by the following formula: Value of car after n years = I(1 - r)^n.

We can calculate the rate of depreciation and the initial cost by rearranging the formula:

r = 1 - (Value of car after n years/I)^(1/n)

I = Value of car after n years/(1 - r)^n

In our case, the value of the car after years is 15,000(0.77) = 11,550. Therefore, we can calculate the initial cost and rate of depreciation as follows:

r = [tex]1 - (11,550/I)^(1/n) = 1 - (11,550/15,000)^(1/n) = 0.77[/tex]

I =[tex]11,550/(1 - 0.77)^n = 15,000[/tex]

Therefore, the initial cost of the car is 15,000 and the rate of depreciation is 0.77.

The measure of each angles are one is 28 and other is 68.

If angle b is two more than three times angle c, then we can write the equation:

b = 3c + 2

Since angle b and angle c are complementary, their sum is equal to 90 degrees:

b + c = 90

We can substitute the value of b from the first equation into the second equation:

3c + 2 + c = 90

4c + 2 = 90

4c = 88

c = 22

So, angle c is 22 degrees and angle b is equal to 3c + 2 = 3 * 22 + 2 = 68 degrees.

The rate of the boat in still water is 27.428571428571427 miles per hour and the rate of the current is 3.4285714285714284 miles per hour.

Let's call the rate of the boat in still water "r" and the rate of the current "c". Then the rate of the boat traveling upstream is "r - c" and the rate of the boat traveling downstream is "r + c".

We can use the following formula to calculate the rate of the boat in still water: r = (distance traveled upstream + distance traveled downstream) / (total time taken)

distance traveled upstream = 96 miles

distance traveled downstream = 96 miles

total time taken = 4 hours + 3 hours = 7 hours

r = (96 + 96) / 7 = 192 / 7 = 27.428571428571427 miles per hour

Next, we can use the formula for the rate of the boat traveling upstream to calculate the rate of the current:

96 = (r - c) * 4

96 = 4r - 4c

4c = 4r - 96

c = r - 24

Substituting the value of r that we found earlier, we get:

c = 27.428571428571427 - 24 = 3.4285714285714284 miles per hour

Therefore, the rate of the boat in still water is 27.428571428571427 miles per hour and the rate of the current is 3.4285714285714284 miles per hour.

The value of the coordinates of the figure after transformation is: A'' = (-3, 3), B'' = (9, 3), and C'' = (9, 12).

The transformation, or f: X X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point. Two-dimensional mathematical figures move about a coordinate plane according to transformations.

From the given figure, the coordinates of A, B, and C are:

A = (-3, -1)

B = (1, -1)

C = (1, 2)

Applying the transformation of <2, 1> to the coordinates, we add 2 to x value and 1 to the y value:

A' = (-3, -1) = (-1, 1)

B' = (1, -1) = (3, 1)

C' = (1, 2) = (3, 4)

Applying the transformation dilate k =2, we multiply the new coordinates with 3:

A'' = (-3, -1) = (-1, 1) = (-3, 3)

B'' = (1, -1) = (3, 1) = (9, 3)

C'' = (1, 2) = (3, 4) = (9, 12)

The number 42 has 4 primitive roots.

Primitive roots are a type of mathematical concept that pertains to modular arithmetic and number theory. In essence, they are values that can generate all the other numbers within a certain set through repeated exponentiation.

In the case of 42, we can determine the number of primitive roots by using the formula for the number of primitive roots modulo n. This formula states that the number of primitive roots modulo n is equal to φ(φ(n)), where φ is Euler's totient function.

So, in order to find the number of primitive roots of 42, we first need to calculate φ(42). Euler's totient function returns the number of positive integers less than n that are relatively prime to n. Since 42 is an even number, it can be easily determined that

=> φ(42) = φ(2 * 3 * 7)

=> (1 - 1/2) * (1 - 1/3) * (1 - 1/7) * 42 = 12.

Next, we need to find φ(12). Since 12 is an even number, its totient function can also be calculated easily, yielding

=> φ(12) = φ(2^2 * 3)

=> (1 - 1/2) * (1 - 1/3) * 4 = 4.

Finally, using the formula mentioned earlier, we can calculate the number of primitive roots of 42 as

=> φ(φ(42)) = φ(12) = 4.

So, to summarize, 42 has 4 primitive roots.

(y - k)²/a² - (x - h)²/b² = 1

Where:

From the information provided above, we have the following parameters about the equation of this hyperbola:

Center (h, k) = (5, -5).

Also, the vertices is given by:
