Answer:

In order for line AE to equal line BF, m/DFB and m/CEA must both be 90°. When this occurs, line AB does not intersect line EF: the two lines are parallel. line AE and line BF represent the perpendicular distances between line AB and line CD. When the two lines are parallel, the perpendicular distance between them is the same throughout their length.

Step-by-step explanation:

Plato Sample Question

When the two lines are parallel, then the perpendicular distance between them is the same throughout their length.

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

In order for line AE to equal line BF, Angle DFB and Angle CEA must both be 90°.

When this occurs, line AB does not intersect line EF then the two lines are parallel.

Thus the line AE and line BF represent the perpendicular distances between line AB and line CD.

When the two lines are parallel, then the perpendicular distance between them is the same throughout their length.

By applying algebra, it can be concluded that the number of candies remaining in the bag can be written as c = 150 - 8s, where s is the number of snacking.

Algebra is a branch of mathematics that uses symbols and mathematical operations, such as addition, subtraction, multiplication, and division to solve problems

Now we apply algebra to solve the problem:

Tyrone takes 8 pieces of candy each time snacking

After snacking 18 times, 6 pieces of candy remained in the bag

So the totals candies eaten = 8 * 18

                                              = 144 candies

Number of candies in the bag = candies eaten + remaining candies

                                                  = 144 + 6

                                                  = 150 candies

If s denotes the number of snacking, then the total number of candies eaten on s snacking = 8s

if c denotes the number of remaining candies, then:

c = total candies - candies eaten

c = 150 - 8s

Thus the number of candies remaining in the bag can be written as c = 150 - 8s, where s is the number of snacking.

On solving this trigonometry, we find that (a) sec(sin⁻¹ \(\frac{12}{13}\)) = \(\frac{13}{5}\) and (b) tan(sin⁻¹ \(\frac{12}{13}\)) = \(\frac{12}{5}\)

(a) To find the exact value of sec(sin⁻¹ \(\frac{12}{13}\)), we can use the fact that sec(x) = \(\frac{1}{cos}\)(x). Let's draw a right triangle with opposite side 12 and hypotenuse 13. Using the Pythagorean theorem, we can find the adjacent side:

a² + b² = c²

a² + 12² = 13²

a² = 169 - 144

a = √25

a = 5

So our triangle has sides of length 5, 12, and 13. Now we can find cos(sin⁻¹  \(\frac{12}{13}\)) by looking at the adjacent/hypotenuse ratio in this triangle:

cos(sin⁻¹ \(\frac{12}{13}\)) =  \(\frac{5}{13}\)

Therefore, sec(sin⁻¹(12/13)) = 1/cos(sin⁻¹ \(\frac{12}{13}\))

                                            = 1/\(\frac{5}{13}\)

                                            = \(\frac{13}{5}\).

So the exact value of sec(sin⁻¹ \(\frac{12}{13}\)) is \(\frac{13}{5}\).

(b) To find the exact value of tan(sin⁻¹ \(\frac{12}{13}\)), we can use the fact that tan(x) = sin(x)/cos(x). Let's use the same right triangle as before.

Then sin(sin⁻¹ \(\frac{12}{13}\))=  \(\frac{12}{13}\) and cos  \(\frac{12}{13}\)) = \(\frac{5}{13}\)  , so

tan(sin⁻¹ \(\frac{12}{13}\)) = sin(sin⁻¹ \(\frac{12}{13}\))/cos(sin⁻¹\(\frac{12}{13}\))

                        = \(\frac{12}{13}\) / \(\frac{5}{3}\)

                        = \(\frac{12}{5}\)

So the exact value of tan(sin⁻¹ \(\frac{12}{13}\)) is \(\frac{12}{5}\).

Step-by-step explanation:

The 500 mg is equal to an approximate of 0.0176 ounces.

To convert milligrams to ounces, we need to consider the following conversion factors:

First, we will convert milligrams to grams:

= 500 mg * (1 g / 1000 mg)

= 0.5 g

Next, we will convert grams to ounces:

= 0.5 g * (1 ounce / 28.3495 g)

= 0.0176 ounces

Therefore, 500 mg is equal to approximately 0.0176 ounces.

The critical points are x = 0, 1/4.The function is decreasing in the interval ( -∞, 0 ) and increasing in the intervals ( 0, 1/4 ) and ( 1/4, ∞ ).

Given function is y= 6x^4 - 2x^3To find the critical points and determine whether the function is increasing or decreasing, follow the steps below: Step 1: Find the first derivative of the function. Step 2: Find the critical points by setting f ' (x) = 0Step 3: Determine the intervals where the function is increasing or decreasing. Step 1: Find the first derivative of the function. The derivative of y = 6x^4 - 2x^3 is given by, dy/dx = 24x^3 - 6x^2Step 2: Find the critical points by setting f ' (x) = 024x^3 - 6x^2 = 0 Factor out 6x^2 from the above equation,6x^2 (4x - 1) = 0Therefore, either 6x^2 = 0 or 4x - 1 = 0i.e. x = 0, 1/4 are the critical points. Step 3: Determine the intervals where the function is increasing or decreasing. To check whether the function is increasing or decreasing, make use of the first derivative test. The intervals will be separated by the critical points: Let us check on the interval ( -∞, 0 ):dy/dx = 24x^3 - 6x^2So, if x < 0, 24x^3 < 0, and 6x^2 > 0. Hence, dy/dx < 0.Therefore, the function is decreasing in the interval ( -∞, 0 )Let us check on the interval ( 0, 1/4 ):dy/dx = 24x^3 - 6x^2So, if 0 < x < 1/4, 24x^3 > 0 and 6x^2 > 0. Hence, dy/dx > 0.Therefore, the function is increasing on the interval ( 0, 1/4 )Let us check on the interval ( 1/4, ∞ ):dy/dx = 24x^3 - 6x^2So, if x > 1/4, 24x^3 > 0 and 6x^2 > 0. Hence, dy/dx > 0.Therefore, the function is increasing on the interval ( 1/4, ∞ ).

The given function is y=6x⁴ - 2x³.The first step to finding critical points is to determine the first derivative of the function. The first derivative of the given function is:

dy/dx = 24x³ - 6x²

Now, to find critical points, set the first derivative to zero and solve for x.

24x³ - 6x² = 0

Factor out 6x² from the left side:

6x²(4x - 1) = 0

Set each factor equal to zero:

6x² = 0 or

4x - 1 = 0

Solving for x in the first equation:

6x² = 0x = 0

The second equation:4x - 1 = 0

⇒ x = 1/4

So the critical points are x = 0

and x = 1/4.

To determine if the function is increasing or decreasing, we need to look at the sign of the first derivative in the intervals formed by the critical points.

When x < 0, dy/dx < 0, so the function is decreasing.

When 0 < x < 1/4, dy/dx > 0, so the function is increasing.

When x > 1/4, dy/dx < 0, so the function is decreasing.

On the interval (-∞, 0), the function is decreasing. On the interval (0, 1/4), the function is increasing. On the interval (1/4, ∞), the function is decreasing.

Answer:

x = -9

Step-by-step explanation:

To solve the equation

Let us do these steps with our question to find x

∵ 4(2x + 7) = 12 - 2(10 - 2x)

→ Simplify each side

∵ 4(2x) + 4(7) = 12 - 2(10) - 2(-2x)

∴ 8x + 28 = 12 - 20 + 4x

→ Add the like terms in the right side

∵ 8x + 28 = (12 - 20) + 4x

∴ 8x + 28 = -8 + 4x

→ Subtract 28 from both sides

∵ 8x + 28 - 28 = -8 - 28 + 4x

∴ 8x = -36 + 4x

→ Subtract 4x from both sides

∵ 8x - 4x = -36 + 4x - 4x

∴ 4x = -36

→ Make coefficient of x equal 1 by dividing both sides by 4

∴ \(\frac{4x}{4}=\frac{-36}{4}\)

∴ x = -9

  (d)  not possible to tell from information given

Step-by-step explanation:

You want to know the total completion time for a project with four activities that take 4, 3, 6, and 7 days.

The project completion time will be determined by the dependencies between activities.

If each activity must be completed before the next, then the total time will be 4+3+6+7 = 20 days.

If there are no dependencies and all activities can be done in parallel, then the total completion time is 7 days, the time required for the longest activity.

In short, it is not possible to determine the total time from the information given.

The surface area, we integrate the circumference of the rings from x = 0 to x = 6: Area = ∫[0,6] 2πy ds = ∫[0,6] 2π(2x^2 + 3) √(1 + (4x)^2) dx. Evaluating this integral will yield the surface area of the solid obtained by rotating the curve y = 2x^2 + 3 from x = 0 to x = 6 about the x-axis is  57.75 square units.

To find the surface area, we divide the curve into small sections and rotate each section around the x-axis to create thin rings. The circumference of each ring can be approximated by the arc length of the corresponding section of the curve.

First, we need to express y in terms of x as y = 2x^2 + 3.

Next, we calculate the differential arc length of the curve section using the formula ds = √(1 + (dy/dx)^2) dx.

In this case, dy/dx = 4x, so the differential arc length becomes ds = √(1 + (4x)^2) dx.

To find the surface area, we integrate the circumference of the rings from x = 0 to x = 6:

Area = ∫[0,6] 2πy ds = ∫[0,6] 2π(2x^2 + 3) √(1 + (4x)^2) dx.
