We have to find the equation of the line perpendicular to the given line:

and passes through the point (-8, 6)

A line perpendicular to another line has a slope that is the negative inverse of the line.

The slope of the given line is 3/4, so the slope of the line we are looking for is -4/3

Now, we use the point slope method to find the equation:

y - y1 = m(x - x1)

where m = slope

(x1, y1) = point the line passes through

So, we have:

That is the equation of the line.

155^A.The measure of LMN in kite KLMN is 155°.

A kite's main characteristic is that it has two pairs of congruent adjacent sides, with one set of diagonally opposite angles being equal, but the other set not. In a kite, these angles have different degree measures.

Kite KLMN has two pairs of adjacent sides that are congruent, and its diagonal is not perpendicular. So, angle KLM is 106°, angle KLN is 99°, and angle KMN is 49°. Since the sum of the internal angles of a quadrilateral is 360 degrees, we can use the following formula to calculate the angle LMN:360 - (angle KLM + angle KLN + angle KMN) = angle LMN360 - (106° + 99° + 49°) = 106°.Therefore, the measure of LMN in kite KLMN is 155°.

The expected number of boys who make good score is found to be 188 by using random sample method.

To get the projected number of boys who get good grades, multiply the total number of boys by the proportion of boys who answered they would like to get good grades the most.

According to the table, the total number of boys surveyed is:

188 +64 +192 = 444

And the percentage of guys who indicated they

would like to get good grades is:

188/444 0.423

As a result, the projected number of guys with good grades is:

Expected number of boys = total number of boys

x percentage of boys who get high grades

444 x 0.423 = 444 boys expected

Number of boys expected = 187.812

When we round to the nearest full number, we get: The expected number of males with good grades

is 188.

Step-by-step explanation:

The slope of the tangent line at (4, 54) is 45. So the equation of the tangent line to the curve y = x^3 - 3x + 2 at the point (4, 54) is y = 45x - 126.

To find the equation of the tangent line to the curve y = x^3 - 3x + 2 at the point (4, 54), we need to use calculus. First, we find the derivative of the function:

y' = 3x^2 - 3

Next, we plug in x = 4 to find the slope of the tangent line at that point:

y'(4) = 3(4)^2 - 3 = 45

So the slope of the tangent line at (4, 54) is 45. To find the equation of the line, we use the point-slope form of the equation:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the point on the line. Plugging in our values, we get:

y - 54 = 45(x - 4)

Simplifying, we get:

y - 54 = 45x - 180

y = 45x - 126

So the equation of the tangent line to the curve y = x^3 - 3x + 2 at the point (4, 54) is y = 45x - 126.

To find the equation of the tangent line to the curve y = x^3 - 3x + 2 at the point (4, 54), we need to first find the derivative of the function and then use the point-slope form of a line.

1. Find the derivative of the function with respect to x:
y'(x) = d/dx (x^3 - 3x + 2) = 3x^2 - 3

2. Evaluate the derivative at the given point (4, 54) to find the slope of the tangent line:
m = y'(4) = 3(4)^2 - 3 = 3(16) - 3 = 48

3. Use the point-slope form of a line (y - y1 = m(x - x1)):
y - 54 = 48(x - 4)

4. Simplify the equation:
y - 54 = 48x - 192
y = 48x - 138

So, the equation of the tangent line to the curve y = x^3 - 3x + 2 at the point (4, 54) is y = 48x - 138.

The probability that the two cards drawn are of different suits is approximately 0.3744 or 37.44%.

The probability that the first card drawn is of a particular suit (say hearts) is 13/52, because there are 13 hearts in the deck. The probability that the second card drawn is of a different suit (say diamonds) is 39/52, because there are 13 cards in each of the three remaining suits.

So, the probability that the first card is a heart and the second card is a diamond is (13/52) × (39/52) = 507/2704.

Similarly, the probability that the first card is a diamond and the second card is a heart is also (13/52) × (39/52) = 507/2704.

The probability that the two cards are of different suits is the sum of these two probabilities:

An equation of the parabola with the given focus and directrix is (x - 4)² = -16(y - 1).

Given that, focus of a parabola at (-4,3) and a directrix at y = 5.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line.

The general equation of a parabola is: y = a(x-h)² + k or x = a(y-k)² +h, where (h, k) denotes the vertex. The standard equation of a regular parabola is y² = 4ax.

The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where

The vertex of the parabola is (h, k)

The focus is (h, k + p)

The directrix is at y = k - p  

Here, the focus of the parabola is (4, -3)

The focus is (h, k + p)

So, h = 4

Then, k + p = -3 --------(1)

It has a directrix of y = 5

The directrix of the parabola is y = k - p

∴ k - p = 5 --------(2)

Add equations (1) and (2) to find k and p, that is

(k + k) + (p - p) = (-3 + 5)

⇒ 2k + 0 = 2

⇒ 2k = 2

Divide both sides by 2

k = 1

Substitute the value of k in equation (1), we get

1 + p = -3

Subtract 1 from both sides, we get

1 - 1 + p = -3 - 1

⇒ p = -4

Substitute the values of h=4, k=1 and p=-4 in (x - h)² = 4p(y - k), that is

(x - 4)² = 4(-4)(y - 1)

⇒ (x - 4)² = -16(y - 1)

Therefore, an equation of the parabola with the given focus and directrix is (x - 4)² = -16(y - 1).

There are 472 more buttons bought by Vance than beads.

For the stated question table is made.

So,

Total number of beads bought by Vance = Number of beads(2 packages of large beads) + Number of beads(1 package of medium beads).

= (2 × 96) + (1 × 64)

= 2 × (90 + 6) + 64

= (2 × 90) + (2 × 6) + 64

= 180 + 12 + 64

= 256 beads

Now,

Total number of buttons bought by Vance = Total number of buttons (2 packages of large buttons) + Number of buttons (2 packages of medium buttons)

= (2 × 56) + (2 × 38)

= 2 × (50 + 6) + 2 × (30 + 8)

= (2 × 50) + (2 × 6) + (2 × 30) + (2 × 8)

= 100 + 12 + 600 + 16

= 728 buttons

Thus,

In the given polygon we have: Slope of A'B' = 5, Length of A'D' = 8.4, Length of C'D' = 5.4, Slope of B'C' = 0.25.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial shape should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.

Enlargement is the term used when a dilatation results in a larger image.

Reduction occurs when a dilatation results in a smaller picture.

When the polygon ABCD is dilate by 1.2 units the slope of the segments of the polygon remains the same, whereas the length of the segments are multiplied by 1.2 units.

Thus.

Slope of A'B' = 5

Length of A'D' = 8.4

Length of C'D' = 5.4

Slope of B'C' = 0.25

Hence, in the given polygon we have: Slope of A'B' = 5, Length of A'D' = 8.4, Length of C'D' = 5.4, Slope of B'C' = 0.25.

hence the equation we frame is:

Equation:

120/x + 220/(x-5) = 6

120(x-5) + 220x = 6x(x-5)

120x - 600 + 220x = 6x² - 30x

The given equation y = 3x + 5 has infinitely many solutions.

What is a linear equation in two variables?

If an equation is written in the form ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables.

Given: Linear equation y = 3x + 5

We know that,

The linear equation in two variables in the form of ax + by + c = 0

For x = 0, y = 0 + 5 = 5. Therefore, (0, 5) is one solution.

For x = 1, y = 3 × 1 + 5 = 8. Therefore, (1, 8) is another solution.

For y = 0, 3x + 5 = 0, x = -5/3. Therefore, (-5/3, 0) is another solution.

Clearly, for different values of x, we get various values for y. Thus, any value substituted for x in the given equation will constitute another solution for the given equation. So, there is no end to the number of different solutions obtained by substituting real values for x in the given linear equation. Therefore, a linear equation in two variables has infinitely many solutions.

Hence, the given equation y = 3x + 5 has infinitely many solutions.
