So the new coordinates of point C are (1, 2), and the image of Triangle ABC is congruent to the original triangle.

A triangle is a closed, two-dimensional geometric figure with three straight sides and three angles. It is one of the basic shapes in geometry and can be classified based on the length of its sides or the size of its angles. A triangle with all sides of equal length is called an equilateral triangle, while a triangle with two sides of equal length is called an isosceles triangle. A triangle with no sides of equal length is called a scalene triangle. Triangles can also be classified based on the size of their angles, with an acute triangle having all angles less than 90 degrees, a right triangle having one angle equal to 90 degrees, and an obtuse triangle having one angle greater than 90 degrees.

Here,

To find the new coordinates of point C after the rotation and translation, we need to perform each transformation separately and then combine them.

Rotation:

To rotate a point 180° counterclockwise about the origin, we switch the sign of both coordinates. Therefore, the new coordinates of point C after the rotation are (-3, -2).

Translation:

To translate a point to the right 4 and up 4, we add 4 to the x-coordinate and 4 to the y-coordinate. Therefore, the new coordinates of point C after the translation are (1, 2).

To determine if the image of Triangle ABC is similar or congruent to the original triangle, we need to compare the corresponding sides and angles of both triangles.

Since we performed a rotation of 180°, all the angles in the image triangle are congruent to the corresponding angles in the original triangle. Additionally, since we performed a translation, the sides of the image triangle are congruent to the corresponding sides of the original triangle. Therefore, the image triangle is congruent to the original triangle.

The form that most quickly reveals the y intercept is

The y intercept is (0, 21/2)

The y-intercept is the point where a function or a curve intersects the y-axis. In other words, it is the value of the dependent variable (y) when the independent variable (x) is equal to zero.

In the form,  f(x) = 1/2 x² - 5x + 21/2 it is easier to see that eliminating x by plugging in 0 leaves 21/2 which is the y intercept

hence we can easily say that the y intercept is (0, 21/2)

It's false the terms " subtracted from " and " less than " means to deduct or use minu (-) operation .

"Subtracted from" and "less than" are terms that mean you need to "turn" or "flip" the terms around. False.

"Subtracted from" and "less than" do not require flipping or turning the terms around.

"Subtracted from" is used in subtraction and indicates that one quantity is being subtracted from another.

For example, in the expression "a - b," "a" is the number from which b is subtracted) and "b" is the number that is subtracted from a.

"Less than" is used in comparisons and represents the relationship between two quantities. It does not require flipping the terms around.

==========================================================

Explanation:

There are 12 choices for the first topping and 11 for the next topping. The decrease is to account for the fact we cannot select a repeat topping.

That gives 12*11 = 132 permutations. If order of toppings mattered, then this would be our final answer.

However, the topping order doesn't matter. So we need to divide by 2 to correct for the double counting.

There are 132/2 = 66 combinations.

------------

Alternative Method:

n = 12 toppings are available and r = 2 selections are allowed

Order doesn't matter so we use the nCr combination formula

\(n C r = \frac{n!}{r!(n-r)!}\\\\12 C 2 = \frac{12!}{2!*(12-2)!}\\\\12 C 2 = \frac{12!}{2!*10!}\\\\12 C 2 = \frac{12*11*10!}{2!*10!}\\\\ 12 C 2 = \frac{12*11}{2!}\\\\ 12 C 2 = \frac{12*11}{2*1}\\\\ 12 C 2 = \frac{132}{2}\\\\ 12 C 2 = 66\\\\\)

There are 66 combinations

Notice the 2nd to last step involves 132/2 which was mentioned in the previous section.

Answer:

62.14 miles per hour

Answer: 100 km/h is equal to 62.14 mph

So, 100 km/h is equal to 62.14 miles per hour.

Answer:

62.15 mi/hr

Step-by-step explanation:

Given:

As both speed limits are given "per hour", we only need to convert 100 km to miles.  To do this, set up and solve a ratio for "miles to kilometers", where x is the number of miles to 100 km:

\(\implies \sf 1 : 1.609 = x : 100\)

\(\implies \sf \dfrac{1}{1.609} = \dfrac{x}{100}\)

\(\implies \sf \dfrac{1}{1.609} \cdot 100= x\)

\(\implies \sf x= \dfrac{100}{1.609}\)

\(\implies \sf x= 62.15040398...\)

Therefore, 100 km/hr = 62.15 mi/hr (2 d.p.)

Answer:

\(A = 89.1327\)

Step-by-step explanation:

1. Approach

To solve this problem, one must divide the figure up into two smaller figures. Calculate the areas of these smaller figures, and then finally, add up the result. The given figure can be divided into a square and a semi-circle. One can solve for the area of the square using the formula (\(length*width=area\)). One can solve for the area of the semicircle by solving for the area of the circle, and then dividing it by (2).

2. Solve for the area of the square

This is the easier part, all one has to do is multiply the length of the square by the width;

\(length * width = area\\\\8 * 8 = area\\\\64 = area\)

3. Solve for the area of the semi-circle

The formula for the area of a circle is;

\((pi)r^2=A\)

Where coefficient (\(pi\)) represent the values (\(3.1415...\)), parameter (\(r\)) represent the radius of the circle, and (\(A\)) represents the area.

In the problem, one is given the diameter of the semicircle. The diameter is the largest cord (a line that is drawn in a circle) in the circle, this cord will pass through the center of the circle. The radius is the distance from the center of the circle to the outer edge of the circle. The radius, by its definition will always be half of the diameter. It is given that the diameter of the given circle is (\(8\)), therefore the radius is (\(4\)), because (\(8\)÷\(2=4\)).

Substitute in the values and solve;

\((pi)(4)^2 = A\\\\3.1415*(16)=A\\\\50.2655=A\)

Don't forget to divide this in half, because the given figure is a semi-circle, not a circle;

\(25.1327\)

4. Putting it together

Now add the value for the area of the semi-circle, with the value for the area of the square;

\(square + semi-circle = Total\ area\\\\64 + 25.1327 = Total\ area\\\\89.1327 = Total\ area\)

The equation of the quartic polynomial in

standard form. f(x) = -4x^4 - 8x^3 + 4x^2 + 64x + 64

Since the zeros of the quartic function are -4, -2, -1, and 2, we know that the function can be factored as:

f(x) = a(x + 4)(x + 2)(x + 1)(x - 2)

where a is some constant.

To find the value of a, we can use the fact that the y-intercept of the function is 64. The y-intercept occurs when x = 0, so we have:

f(0) = a(4)(2)(1)(-2) = -16a = 64

Solving for a, we get a = -4.

Substituting this into the factored form of the function, we get:

f(x) = -4(x + 4)(x + 2)(x + 1)(x - 2)

Expanding this expression, we get:

f(x) = -4x^4 - 8x^3 + 4x^2 + 64x + 64

This is the quartic polynomial in standard form.

Answer:

wouldnt the value of x be r?

The annual percentage rate (APR) for the loan of $3,600 at 8% add-on interest for 3 years is 15.6%.

The annual percentage rate is the nominal or effective interest rate charged on a loan for a year, unlike the Monthly Percentage Rate (MPR), which is a monthly rate.

The annual percentage rate can be calculated by using the formula:

APR = 2Nr/N + 1

N = number of payments

r = the add-on interest rate

N = 3 years = 36 months (12 x 3)

r = 8% or 0.08 (8/100)

APR = (2 x 36 x 0.08)/(36 + 1)

= 5.76/37

= 0.15.57

= 15.57%

= 15.6%

Thus, with an 8% interest rate for 3 years, the APR is 15.6%.

The value of N that satisfies the following equation, 5!9!= 12N!, is 10.

Factorial notation (n!) means to multiply a series of descending natural numbers. Also stated in the problem that for positive integer n, the factorial notation n! represents the product of the integers from n to 1.

Take for example 6! which can be written as 6 x 5 x 4 x 3 x 2 x 1 = 720.

Given the equation 5!9!= 12N!, expand the factorial notation.

(5 x 4 x 3 x 2 x 1)(9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = (4 x 3) N!

N! = (5 x 2 x 1)(9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)

N! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

N = 10

Therefore, the value of N that satisfies the following equation, 5!9!= 12N!, is 10.
