The equation of the tangent line to the curve is derived by first finding the slope of the tangent line at a certain point using implicit differentiation. After finding the slope, we then use the point-slope form of a linear equation to get the equation of the tangent line.

To find an equation of the tangent line to the curve given by the equation xey + yex = 5, it's necessary to find the derivative of the function, which gives us the slope of the tangent line at any point. Implicit differentiation is the key here, since y is not explicitly solved in terms of x.

Differentiating the given equation implicitly with respect to x, we get: exy + yex +ex + yex = 0. From this, we can express dy/dx (the derivative of y with respect to x, i.e., the slope of the tangent line) in terms of x and y.

Next, simply plug in the given coordinates of the point at which we are finding the tangent into this dy/dx equation. This gives the slope of the tangent line at the specific point.

To finally find the equation of the tangent line, use the point-slope form of a linear equation y - y1 = m(x - x1), where m is the slope we found, and (x1, y1) are the coordinates of the point. Substitute these values in, and that gives the equation of the tangent line to the curve at the point.

Answer: y+9=-4(x-4)

Step-by-step explanation:

A P E X

The given equation in slope-intercept form is y = -2x - 2.

Slope of a line is defined as the change in the value of y-coordinate with respect to the x-coordinate value. It is usually denoted by 'm'.

It can also be defined as the tangent of the angle that the given line is making with the X-axis.

That is m = tan θ, where θ is the angle that line is making with the X-axis.

The equation of a line in slope-intercept form is given by,

y = mx + c

Here, c is called the y-intercept, the value of which is the value of the y-coordinate when the line touches the Y-axis.

Now,

y + 4 = -2 (x - 1)

y + 4 = -2x + 2

y = -2x + 2 - 4

y = -2x - 2

The equation of the line in slope-intercept form is y = -2x - 2.

Therefore, [tex]\frac{18}{25}[/tex] is equal to 72%.

Answer:

The area of the triangle is, [tex]56 cm^2[/tex]

Step-by-step explanation:

Area of the triangle(a) is given by:

[tex]a = \frac{1}{2} \cdot bh[/tex]           ....[1]

where,

b is the base and h is the height of the triangle.

As per the statement:

Given:

h = 8 cm

b = 14 cm

Substitute in [1] we have;

[tex]a = \frac{1}{2} \cdot 8 \cdot 14 = 4 \cdot 14[/tex]

⇒[tex]a = 56 cm^2[/tex]

Therefore, the area of the triangle is, [tex]56 cm^2[/tex]

The solutions of the quadratic equation [tex]8m^2 + 20m = 12[/tex] by factoring method are [tex]m = \dfrac{1}{2}[/tex] and [tex]m = - 3[/tex]

Using the formula of the quadratic equation which states that,

The roots of the standard form of a quadratic equation [tex]ax^2 + bx + c = 0[/tex] are calculated as,

[tex]x = \dfrac{- b \pm \sqrt{b^2 - 4ac} }{2a}[/tex]

Given that,

A quadratic equation,

[tex]8m^2 + 20m = 12[/tex]

Now, simplify the equation,

[tex]8m^2 + 20m = 12[/tex]

Subtract 12 on both sides,

[tex]8m^2 + 20m - 12 = 0[/tex]

Take 4 as a common term,

[tex]4 (2m^2 + 5m - 3) = 0[/tex]

Since, [tex]4 \neq 0[/tex]

[tex]2m^2 + 5m - 3 = 0[/tex]

Apply the factoring method in the above equation,

[tex]2m^2 + 5m - 3 = 0[/tex]

[tex]2m^2 + (6 - 1)m - 3 = 0[/tex]

[tex]2m^2 + 6m - m - 3 = 0[/tex]

[tex]2m (m + 3) - 1(m + 3) = 0[/tex]

[tex](2m - 1) (m + 3) = 0[/tex]

This gives two solutions,

[tex]2m - 1 = 0\\2m = 1\\m = \dfrac{1}{2}[/tex]

[tex]m + 3 = 0\\m = - 3[/tex]

Aidan makes 8 bracelets each day from Tuesday to Thursday, resulting in 24 bracelets for those three days. Adding this to the 12 he made on Monday gives us 36 bracelets up to Thursday. Aidan continues the same pattern on Friday, making 8 more bracelets, totaling 44 bracelets.

To determine how many bracelets Aidan makes on Friday, we need to calculate the total number he makes from Tuesday through Thursday and then add it to the number of bracelets he already made on Monday. He starts with 12 bracelets on Monday and makes 8 more each day from Tuesday to Thursday. Calculating the bracelets made from Tuesday through Thursday involves multiplication of the daily bracelet count by the number of days.

Aidan makes 8 bracelets each day for three days, which is calculated as follows:

We then add this to the initial 12 bracelets made on Monday:

Since the pattern of bracelet making doesn’t specify any change on Friday, we assume Aidan continues to make 8 bracelets on Friday as well. So, he makes 8 bracelets on Friday.

The total number of bracelets Aidan makes up to Friday is the sum of bracelets made from Monday through Thursday plus the bracelets made on Friday:

Final answer:

Aidan makes 44 bracelets on Friday.

Explanation:

To find out how many bracelets Aidan makes on Friday, we need to calculate the total number of bracelets he makes from Monday through Thursday. On Monday, Aidan makes 12 bracelets. From Tuesday through Thursday, he makes 8 more bracelets each day. So the number of bracelets he makes on Tuesday is 12 + 8, on Wednesday is 12 + 8 + 8, and on Thursday is 12 + 8 + 8 + 8.

Now, to calculate the number of bracelets he makes on Friday, we need to add 8 to the total number of bracelets he made on Thursday. So the total number of bracelets he makes on Friday is 12 + 8 + 8 + 8 + 8.

Therefore, Aidan makes 12 + 8 + 8 + 8 + 8 = 44 bracelets on Friday.

Final answer:

Bobby has 12 tech decks, Ricky has 20 tech decks, and Terry has 36 tech decks.

Explanation:

Let's represent the number of tech decks each child has using variables.

Let's say Bobby has x tech decks. Since Ricky has 8 more tech decks than Bobby, Ricky has x + 8 tech decks. Terry has triple the number of tech decks that Bobby has, so Terry has 3x tech decks.

Now, we can set up an equation to represent the total number of tech decks:

x + x + 8 + 3x = 68

5x + 8 = 68

5x = 60

x = 12

So, Bobby has 12 tech decks, Ricky has 12 + 8 = 20 tech decks, and Terry has 3 * 12 = 36 tech decks.

The answer would be negative 9 (-9)

Answer:

[tex]g(f(x))=-9x^2[/tex]

Step-by-step explanation:

[tex]f(x) = -3x^2[/tex]

[tex]g(x) = 3x[/tex]

WE need to find composition of function g(f(x))

To find g(f(x)) we replace f(x) in g(x)

[tex]g(f(x))= g(-3x^2)[/tex]

Now we replace -3x^2 inside g(x)

[tex]g(-3x^2)=3(-3x^2)= -9x^2[/tex]

[tex]g(f(x))=-9x^2[/tex]

Answer:

linear increasing

Step-by-step explanation:

By applying the concept of Least Common Multiple (LCM), which is 12 in this case, we realize that Eddie will perform all three activities on the same day again after 12 days and that the day will be a Friday.

If Eddie goes jogging every other day (2 days), lifts weights every third day (3 days), and swims every fourth day (4 days), then we must find the LCM of 2, 3, and 4 to find out when will he do all three activities on the same day again.

The LCM of 2, 3, and 4 is 12. Therefore, Eddie will perform all three activities on the same day after 12 days. If he begins on Monday, he will surprisingly end up on a Friday, as the 12th day falls on a Friday. This is because, typically, 7 days from Monday is another Monday. Therefore, five additional days (to total 12) will fall on a Friday.

The correct option that describes the volume of a cylinder is B: the area of the circular base multiplied by the height of the cylinder, represented by the formula \(V = \pi r^2 h\).

The volume of a cylinder is best described by option B, which states it is the area of the circular base multiplied by the height of the cylinder. The area of the base, which is a circle, is calculated using the formula \\(\pi r^2\), where \(r\) represents the radius of the circle. To find the volume, this area is then multiplied by the height \(h\) of the cylinder, giving the formula for the volume \(V = \pi r^2 h\).
