Option D will result in an image that is rotated 180 degrees equation counterclockwise about the origin and then reflected across the y-axis, which will not map the image onto itself.

Counterclockwise, also known as anticlockwise, is a direction of rotation that is opposite to the direction in which the hands of a clock move. It is the direction that is typically associated with the rotation of objects in the Northern Hemisphere.

counterclockwise rotation is the positive direction of rotation in a coordinate system, where the x-axis increases to the right and the y-axis increases upwards.

Option B, "Reflect over the y-axis, and then reflect again over the y-axis," will result in an image that maps onto itself.

When you reflect an image over the y-axis, the left and right sides of the image switch places. If you then reflect the already reflected image over the y-axis again, the left and right sides switch places once more, effectively returning the image to its original orientation.

Option A will result in an image that is rotated 180 degrees counterclockwise about the origin and then reflected across the x-axis, which will not map the image onto itself.

Option C will result in an image that is reflected over the y-axis and then reflected over the x-axis, which will produce an image that is flipped both horizontally and vertically and therefore not map the image onto itself.

Option D will result in an image that is rotated 180 degrees counterclockwise about the origin and then reflected across the y-axis, which will not map the image onto itself.

The equation of the line tangent to the graph of y = cos(x) at x = π/2 is y = -x + π/2. The correct option is C. y = -x + π/2.

To find the equation of the line tangent to the graph of y = cos(x) at x = π/2, we need to find the derivative of the function and evaluate it at x = π/2. The derivative of y = cos(x) is given by dy/dx = -sin(x).

Now, let's evaluate the derivative at x = π/2:

dy/dx = -sin(π/2) = -1

The derivative gives us the slope of the tangent line at x = π/2. Therefore, the slope of the tangent line is -1.

Now, we have the slope of the tangent line and the point (π/2, cos(π/2)) on the line. Using the point-slope form of a line, y - y1 = m(x - x1), where (x1, y1) is a point on the line, we can write the equation of the tangent line:

y - cos(π/2) = -1(x - π/2)

Since cos(π/2) = 0, the equation simplifies to:

y = -x + π/2

Therefore, the equation of the line tangent to the graph of y = cos(x) at x = π/2 is y = -x + π/2.

Hence, the correct option is C. y = -x + π/2.

Step-by-step explanation:

If Sₙ denotes the sum of the reciprocals of the non-zero digits of the integers from 1 to 10ⁿ inclusive , then the smallest positive integer n for which Sₙ is an integer is 63 .

The "Sₙ" be the sum of reciprocals of the non-zero digits of the integers from 1 to 10ⁿ inclusive ;

We Let \(K= \sum_{i=1} ^{9} \frac{1}{i}\) ,

On further examination , we get that , \(S_{1} =K+1\) ;

Since each digit "n" appears once and the number 1 appears for an extra time.

Now , we write  S₂ .

So ,Each term of K will appear 10 times in the units place and 10 times in the tens place ,

So , we get \(S_{2} = (n10^{n-1})K+1\) ; and there are total "n" places ;

The denominator of K is written as \(D=2^{3} .3^{2} .5.7\) .

For Sₙ to be an integer, \(n10^{n-1}\) must be divisible by D , we must select "n" to be divisible by \(3^{2} .7\)   .

And since need to find the smallest integer "n" , So , the n is \(3^{2} .7 = 63\) .

Therefore , For Sₙ to be an integer , the smallest positive integer n is 63 .

The given equation is 8x - 6(4x) + 11(2x) - 6 = 0.To solve the above equation, we need to simplify it by using the distributive property and combining like terms.

\(8x - 24x + 22x - 6 = 0 6x - 6\)

Answer: The study indicated that residents of Springtown wasted 7,622 gallons of water this year, which is 85% more than they wasted last year. To find out how many gallons of water the city's residents wasted last year, we need to find out what 85% of 7,622 gallons is and then subtract that amount from the total amount wasted this year.

85% of 7,622 gallons is (85/100) * 7,622 = 6,465.7 gallons

So, if residents of Springtown wasted 7,622 gallons of water this year, which is 85% more than they wasted last year, then they wasted 7,622 - 6,465.7 = 1,156.3 gallons of water last year.

Step-by-step explanation:

Answer:

x = 4120 gallons wasted last year

Step-by-step explanation:

Let x be the amount of water wasted by the residents of Springtown "last year."

They wasted 85% more this year.  This would mean that x*(1+ 0.85) = 7622 gallons.  [The "(1+0.85)" represents the decimal equivalent to "85% more."

x*(1+ 0.85) = 7622

1.85x = 7622

x = 4120 gallons wasted last year

Check:

Is 7622 85% more than 4120?

(7622-4120)=3502

(3502/42=4120) = 0.85  YES

the sum of slices needs to be 66 and canot exceed 10 pizzas in total.

6x4=24 slices

8x6=42 slices

4+6= 10 so it does not exceed 10 pizzas.

24 +42= 66 so there are 66 slices.

The resulting equation written in standard form is 16x² - 22x + 6 = 0.

Answer:

\( x = 5 \)

Step-by-step explanation:

DS = 4x + 12

SE = 8x - 8

Since segment RS bisects segment DE, it implies that the two segments created, segments DS and SE, are congruent. Therefore:

\( 4x + 12 = 8x - 8 \)

Solve for x

\( 4x + 12 - 8x = 8x - 8 - 8x \) (Subtraction property of equality)

\( -4x + 12 = - 8 \)

\( -4x + 12 - 12 = - 8 - 12 \) (subtraction property of equality)

\( -4x = - 20 \)

\( \frac{-4x}{-4} = \frac{-20}{-4} \)

Answer: Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle

Step-by-step explanation:

No, the line passing through  (-4, 26) and (-2, 0) is  not parallel to line passing through (10, 18) and (5, 3) because slopes of both lines are different.

Line is possible in 2-d forms so, it has only x and y-co-ordinates. Z-co-ordinates is not possible.

We know very well that to prove any two lines are parallel to each other we need to prove only whether their slopes are equal or not.

Now, talking about the slopes we know that if any line is passing from point(x₁,y₁) and again passing from other point(x₂,y₂) then slope(m) of that line is given by the formula=(y₂-y₁) / (x₂-x₁)

So, for first line we have (x₁, y₁)=(-4,26)

and (x₂, y₂)=(-2,0)

So, slope(m₁) of first line is =(0-26)/(-2 - (-4))

                  =>m₁ = -26/2

                   =>m₁ = -13     ----(eq1)

Similarly, for second line, we have (x₁, y₁)=(10,18)

and (x₂, y₂)=(5,3)

So, slope(m₂) of second line is =(3-18) / (5-10)

                =>m₂ = -15/-5

                 =>m₂=     3   -------(eq2)

On comparing eq1 and eq2,we get

 =>m₁≠m₂.
