What is function ?

A function is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.

The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs. A mapping from A to B will only be a function if every element in set A has one end and only one image in set B. Let A & B be any two non-empty sets.

Answer:

C. Elements are listed on the periodic table

Step-by-step explanation:

The given triangle is rotated about 180 degrees and as such, we can say that the triangle CBF is congruent to the triangle EDF.

From the attached image, we see that CB is parallel to ED. We also see that the transversal lines are  BD and CE.

The point E will become the image of point C by a rotation of 180° around the point F.

Now, the point D will be the image of point B by a rotation of 180° around the point F.

Rotation is a type of transformation and as such  ΔEDF will be the image of  ΔCBF.

Therefore we can conclude that ΔCBF ≅ ΔEDF

The second way to prove this congruency is as follows;

∠B = ∠D  (Due to the fact that alternate angles are congruent)

∠C = ∠E  (Due to the fact that alternate angles are congruent)

Now, since CB ≅ ED , then it means that ΔCBF ≅ ΔEDF by SAS congruency postulate

Answer:

a = 9

Step-by-step explanation:

The given trinomial is :

\(x^2-6x+\_\_\__\)

let the blank is a.

So, we need to find the value of a so that it results in a perfect square trinomial.

We know that, \((m-n)^2=m^2-2mn+n^2\)

So,

\(x^2-6x+a=x^2-2(1)(3)+3^2\\=(x-3)^2\)

So, the value of a is 9. If a is 9, then only it would be a perfect square trinomial.

The speed of the car is 108 kilometers per hour and the distance covered in 5 hours is 540 kilometers.

Speed is simply referred to as distance traveled per unit time.

It is expressed as;

Speed = Distance ÷ time.

Given that the car is traveling at a rate of 30 meters per second.

First, convert the car's speed from meters per second to kilometers per hour using the conversion factor.

1 kilometer = 1000 meters

1 hour = 3600 seconds

Hence;

Speed = 30m/s = ( 30 × 3600/1000 )kmh

Speed = 108 kmh

Next, the distance covered in 5 hours will be:

Speed = Distance / time

Distance = speed × time

Distance = 108 kmh × 5 h

Distance = 540 km

Therefore, the disatnce covered is 540 kilometers.

The circumferance of a circle with radius of 6cm is 37.68cm

To find:

Circumferance of a circle

Given:

Radius of circle is 6cm

Solution:

Circumference is similar to perimeter as it is the total length required to draw a circle.

Let c be the perimeter.

c = 2πr

or

c = πd

This depends on knowing the radius (r) or diameter (d).

For example, let's calculate it manually.

If r = 6 cm, the circumference in π is c = 2π(6) = 12π cm.

The set of ordered pairs that represents a function is (D) {(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}.

A set of ordered pairs represents a function if each unique input (x-value) is associated with only one output (y-value).

{(-4, -3), (-2, -1), (-2, 0), (0, -2), (0, 2)}

In this set, both (-2, -1) and (-2, 0) have the same x-value but different y-values. Therefore, this set does not represent a function.

{(-5, -5), (-5, -4), (-5, -3), (-5, -2), (-3,0)}

In this set, all the ordered pairs have the same x-value (-5). Since (-5, -5), (-5, -4), (-5, -3), and (-5, -2) have the same x-value but different y-values, this set does not represent a function.

{(-4, -5), (-4, 0), (-3, -4), (0, -3), (3, -2)}

In this set, (-4, -5) and (-4, 0) have the same x-value but different y-values. Therefore, this set does not represent a function.

{(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}

In this set, each unique x-value is associated with a single y-value. There are no repeated x-values. Therefore, this set represents a function.

The factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).

To determine the factors of the polynomial x^3 - 12x^2 - 2x + 24 by grouping, we can follow these steps:

Step 1: Group the terms in pairs. In this case, we can pair the first two terms and the last two terms:

(x^3 - 12x^2) + (-2x + 24)

Step 2: Factor out the greatest common factor from each pair. From the first pair, we can factor out x^2, and from the second pair, we can factor out -2:

x^2(x - 12) - 2(x - 12)

Step 3: Notice that we now have a common binomial factor of (x - 12) in both terms. Factor out this common binomial factor:

(x - 12)(x^2 - 2)

Therefore, the factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).

The midpoint of the line segment of the endpoints (6,-6) and (1,2) is given as:

(3½,-1)

What is the midpoint of a line segment in geometry?

The midpoint of a line segment is simply the centre point of a give segment that cuts or divides it into two congruent segments.

That is for example, if there are two points with coordinates (x1,y1) and (x2,y2), then their midpoint will be ; [(x1+x2)÷2,(y1+y2)÷2]

From the given question!

x1=6, x2=1 and y1=-6,y2=2

Thus, the midpoint is derived as;

[(6+1)÷2,(-6+2)÷2]

[(7)÷2,(-4)÷2]

(3½,-1).

Answer:

\(\sin(1395)=-\frac{\sqrt 2}{2}\\\cos(1395)=\frac{\sqrt 2}{2}\\\tan(1395)=-1\)

Step-by-step explanation:

First, instead of doing 1395, let's find its coterminal angles. We can do so by subtracting 360 until we reach a solvable range. So:

\(1395-360=1035\)

This is still too high, continue to subtract:

\(1035-360=675\\675-360=315\\315-360=-45\)

So, instead of 1395, we can use just -45.

So, evaluate each trig function for -45:

1)

\(\sin(1395)=\sin(-45)\)

Remember that we can move the negative inside of the sine outside. So:

\(=-\sin(45)\)

Remember the sine of 45 from the unit circle:

\(=-\frac{\sqrt2}{2}\)

2)

\(\cos(1395)=\cos(-45)\)

Remember that we can ignore the negative inside of a cosine function. So:

\(=\cos(45)\)

Evaluate using the unit circle:

\(=\frac{\sqrt 2}{2}\)

Now, remember that tangent is sine over cosine. So: "

\(\tan(1395)=\tan(-45)=\frac{\sin(-45)}{\cos(-45)}\)

We already know them. Substitute:

\(=\frac{-\frac{\sqrt 2}{2}}{\frac{\sqrt 2}{2}}\)

Simplify:

\(=-1\)

And we're done!

The limit of the given function as x approaches 1 is 0.

To find the limit of the given function as x approaches 1, we need to evaluate the expression by substituting x = 1. Let's break it down step by step:

1. Begin by substituting x = 1 into the numerator:

\(\[12\sin\left(\frac{\pi}{2}\cdot 1\right)\ln(1) = 12\sin\left(\frac{\pi}{2}\right)\ln(1) = 12(1)\cdot 0 = 0\]\)

2. Now, substitute x = 1 into the denominator:

(1³ + 5)(1 - 1) = 6(0) = 0

3. Finally, divide the numerator by the denominator:

0/0

The result is an indeterminate form of 0/0, which means further analysis is required to determine the limit. To evaluate this limit, we can apply L'Hôpital's rule, which states that if we have an indeterminate form 0/0, we can take the derivative of the numerator and denominator and then evaluate the limit again. Applying L'Hôpital's rule:

4. Take the derivative of the numerator:

\(\[\frac{d}{dx}\left(12\sin\left(\frac{\pi}{2}x\right)\ln(x)\right) = 12\left(\cos\left(\frac{\pi}{2}x\right) \cdot \left(\frac{\pi}{2}\right) \cdot \frac{-1}{x} + \frac{\sin\left(\frac{\pi}{2}x\right)\ln(x)}{x}\right)\]\)

5. Take the derivative of the denominator:

\(\[\frac{d}{dx}\left((x^3 + 5)(x - 1)\right) = \frac{d}{dx}\left(x^4 - x^3 + 5x - 5\right) = 4x^3 - 3x^2 + 5\]\)

6. Substitute x = 1 into the derivatives:

Numerator: \(\[12\left(\cos\left(\frac{\pi}{2}\right) \cdot \left(\frac{\pi}{2}\right) \cdot \frac{-1}{1} + \sin\left(\frac{\pi}{2}\right) \cdot \frac{\ln(1)}{1}\right) = 0\]\)

Denominator: 4(1)³ - 3(1)² + 5 = 4 - 3 + 5 = 6

7. Now, reevaluate the limit using the derivatives:

lim as x approaches 1 of \(\[\frac{{12\left(\cos\left(\frac{\pi}{2}x\right) \cdot \left(\frac{\pi}{2}\right) \cdot \frac{{-1}}{{x}} + \sin\left(\frac{\pi}{2}x\right) \cdot \frac{{\ln(x)}}{{x}}\right)}}{{4x^3 - 3x^2 + 5}}\]\)

= 0 / 6

= 0

Therefore, the limit of the given function as x approaches 1 is 0.

Based on the number of miles that Reshanda rode on her bicycle from her house, her average rate over the last 7 hours of the trip was 7 miles per hour

The average rate shows the speed that a person was going over a period of time such that they were able to cover a certain distance, in that period of time.

First, find the number of miles that Reshanda rode in the last 7 hours of her trip on the bicycle:

= Number of miles after 11 hours - Number of miles after 4 hours
= 79 miles - 30 miles

= 49 miles

Reshanda was able to ride for 49 miles in the last 7 hours so her average rate was:
