A rectangle has a width that is 16 feet shorter than its length and an area that is 35 square feet. The rectangle's length and breadth can be calculated using the equation [tex]3x^2[/tex] - 16x - 35 = 0.

Assume that the rectangle measures "x" feet in length. Then, according to the problem:

The width is 16 feet less than 3 times the length, so the width is 3x - 16 feet.

The area of the rectangle is 35 square feet, so we can write:

Area = Length x Width

35 = x(3x - 16)

To solve for x, we can simplify this quadratic equation by expanding the right-hand side and moving all the terms to one side:

35 = [tex]3x^2[/tex] - 16x

[tex]3x^2 - 16x - 35 = 0[/tex]

The rectangle's length and breadth can be calculated using the quadratic equation shown above.

Answer:

e = 10

Step-by-step explanation:

Vertically opposite angles are the angles formed opposite to each other when two lines intersect.

Vertically opposite angles are equal.

          9e - 8 = 8e + 2

Add 8 to both sides,

                 9e = 8e + 2 + 8

                 9e = 8e + 10

Subtract '8e' from both sides,

         9e - 8e = 10

                   [tex]\boxed{\bf e = 10}[/tex]

Answer:

e = 10

Step-by-step explanation:

According to the Vertical Angle Theorem, when two straight lines intersect, the opposite vertical angles are congruent.

Since the two given angles are vertical angles, they are congruent.

Therefore, we can set them equal to each other:

[tex]\implies (9e - 8)^{\circ} = (8e + 2)^{\circ}[/tex]

[tex]\implies 9e - 8= 8e + 2[/tex]

To solve for e, begin by subtracting 8e from both sides of the equation:

[tex]\implies 9e - 8-8e= 8e + 2-8e[/tex]

[tex]\implies e - 8= 2[/tex]

Add 8 to both sides of the equation:

[tex]\implies e - 8+8= 2+8[/tex]

[tex]\implies e=10[/tex]

Therefore, the value of e is 10.

Answer:

The sum of the exterior angles of any polygon, regardless of the number of sides, is always 360 degrees. Each exterior angle of a regular octagon measures 45 degrees, because the sum of the interior and exterior angles at each vertex is 180 degrees, and the octagon has 8 vertices. Therefore, the sum of all the exterior angles of an octagon is:

8 × 45º = 360º

So the answer is option B) 360º.

Answer:

The rocket splashes down after [tex]\boxed{24}[/tex] seconds

The rocket peaks at [tex]\boxed{769}[/tex] meters above sea-leval

Step-by-step explanation:

The relationship between height and time is given by the equation
[tex]h(t) = -4.9t^2+112t+129[/tex]

The splashdown will occur when [tex]h(t) = 0[/tex]

Therefore solve t for
[tex]-4.9t^2+112t+129 = 0[/tex]

This is a quadratic equation which can be solved with the aid of a quadratic formula calculator

The solution set for this equation is
[tex]t=-1.09894 \;and\;\:t=23.95609\right)[/tex]

Omitting the negative value we get
[tex]\text{t=23.95609 \;seconds}\\\\= 2\text{4 \;seconds \;rounded}}[/tex]

For the second part, the maximum value of h(t) can be found by finding the first derivative h'(t) and setting it equal to 0 and solving for t; then plug this value of t into h(t) to find the max height

[tex]h'(t) = \dfrac{d}{dt}\left(-4.9t^2+112t+129\right)\\\\= \dfrac{d}{dt}\left(4.9t^2\right)+\dfrac{d}{dt}\left(112t\right)+\dfrac{d}{dt}\left(129\right)\\\\= - 9.8t + 112 + 0\\\\= -9.8t + 112\\\\[/tex]

Setting  the above expression to 0 gives
[tex]-9.8t+112=0\\\\-9.8t = -112\\\\t = \dfrac{-112}{-9.8}\\\\t = 11.4286 \;seconds[/tex]

Plugging this value back into h(t) gives

[tex]h(11.4286) = -4.9\cdot \:11.4286^2+112\cdot \:11.4286+129\\\\= 769 \;meters \;(rounded)[/tex]

Inequality to find the value of p is 7p - 12 ≤ 45. So correct option is C.  The value of p is at most 8.14 centimeters.

Inequalities can be solved in a similar way to equations, but with some important differences. To solve an inequality, one must find the set of values that satisfy the inequality. This set of values is often expressed as an interval, which is a range of values between two endpoints. For example, the solution to the inequality x < 5 is the interval (-∞, 5), which includes all values of x that are less than 5. The solution to an inequality may also be expressed graphically on a number line or coordinate plane.

The perimeter of an isosceles triangle with sides of length 3p-6, 3p-6, and p is:

Perimeter = (3p-6) + (3p-6) + p

= 7p - 12

We are given that the perimeter is at most 45 centimeters. Therefore, we can write the following inequality to find the value of p:

7p - 12 ≤ 45

Adding 12 to both sides, we get:

7p ≤ 57

Dividing both sides by 7, we get:

p ≤ 8.14

Therefore, the value of p is at most 8.14 centimeters.

Step-by-step explanation:

If we dissect the image, we can see that triangle LMN there are two similar triangles; triangle LMN and smaller triangle OPN. By definition of similar triangles, corresponding parts of similar triangles will have the same ratios. So, as we can see, sides NP and NM are corresponding. The ratio of the two sides is 24/44 (just put the smaller side over the longer side). Simplified, the ratio is 6/11. So, we know that the opposite sides' ratio will also be 6/11. So, all we have to do is multiply NL (33) by 6/11, which equals 18.

Check:

24/44=6/11, and 18/33=6/11, so the ratios are the same.

a. To find the speed at which the car achieves maximum fuel economy, we need to find the vertex of the function. The vertex of a quadratic function is given by the formula: (-b/2a, f(-b/2a)). In this case, a = -0.008 and b = 1.4. Substituting these values, we get:

Vertex = (-b/2a, f(-b/2a))

= (-1.4/(2*(-0.008)), f(1.4/(2*(-0.008))))

= (87.5, 6.125)

Therefore, the car should travel at a speed of 87.5 miles per hour to achieve maximum fuel economy.

b. To find the maximum fuel economy, we need to find the value of the function at the vertex. Substituting x = 87.5 in the function, we get:

f(87.5) = -0.008(87.5)^2 + 1.4(87.5) = 6.125

Therefore, the maximum fuel economy of the car is 6.125 miles per gallon.

c. To find the fuel economy of the car if it travels at 60 miles per hour, we need to evaluate the function at x = 60. Substituting x = 60 in the function, we get:

f(60) = -0.008(60)^2 + 1.4(60) = 7.6

Therefore, the fuel economy of the car if it travels at 60 miles per hour is 7.6 miles per gallon.

d. The point (40, 43.2) lies on the graph of the function. This means that when the car travels at a speed of 40 miles per hour, its fuel economy is 43.2 miles per gallon. However, this point does not provide any information about the maximum fuel economy or the speed at which it is achieved.

The probability of having 4 hurricanes in a year is approximately 0.118 or 11.8%.

It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

a. To find the probability of having exactly 4 hurricanes in a year, we use the Poisson distribution with a mean of 6.6:

P(X=4) = (e^-6.6)×(6.6^4)/(4!) ≈ 0.118

Therefore, the probability of having 4 hurricanes in a year is approximately 0.118 or 11.8%.

b. In a 35-year period, the expected number of years with 4 hurricanes is:

μ = λt = 6.635 ≈ 231

Therefore, we can expect to have 231 years with 4 hurricanes in a 35-year period.

c. If in a recent period of 35 years, only 3 years had 4 hurricanes, this is less than what the Poisson distribution would predict (231 years). However, this doesn't necessarily mean that the Poisson distribution doesn't work well here. The Poisson distribution is a theoretical model that assumes certain conditions, and it's possible that those conditions weren't met in this specific case. It's also possible that this was just a rare event that can happen due to chance. Further analysis would be needed to determine whether the Poisson distribution is a good fit for this data.

The solution to a system of equations is the point at which the lines defined by the equations intersect.

On this graph, we can see that the lines meet a point on the graph that is at 1 on the x-axis (horizontal axis) and at 2 on the y-axis (vertical axis).

In Cartesian coordinates, this is written in the format (x, y):

(1, 2)

The proportional and inverse relationships can be presented as follows;

1. The value of y when x = 36 is 6

2. The value of y when x = 1 is 27

3. The time of fall of an object that falls 144 feet is 3 seconds

4. The length of the string that vibrates 64 times per second is 48 inches long

A proportional relationship is one that can be expressed in the form; y = k × x.

The possible questions, obtained from a similar question posted online, are presented as follows;

1. y varies directly as the square root of x, when y = 4, x = 16, to find y when x = 36;

The value of y can be found by expressing the relationship between y and x using a proportional relation as follows;

y ∝ √x

y = c·√x

4 = c·√(16) = 4·c

Therefore;

c = 4/4 = 1

c = 1

When x = 36, we get;

y = 1 × √(36) = 6

2. The variation of y and x can be presented as follows;

y ∝ 1/x³

y = c/x³

y = 1, when x = 3, therefore;

1 = c/3³ = c/27

c = 27 × 1 = 27

c = 27

The value y when x = 1, can be found as follows;

y = 27/1³

y = 27/1³ =27

3. The relationship between the distance and the time duration the ball can be presented as follows;

Let s represent the distance the ball falls, and let t represent the time the ball falls, we get;

s = k·t²

The distance an object falls in one second = 16 feet

Therefore, we get;

When s = 16, t = 1

16 = k × 1²

k = 16/1² = 16

k = 16

s = 16·t²

When s = 144 feet, we get;

144 = 16 × t²

t² = 144/16 = 9

t = √9 = 3

4. The relationship between the vibration of a string and the tension in the string can be presented as follows;

Let f represent the vibration of the string, and let l represent the length in the string, we get;

f ∝ 1/l

f = c/l

When l = 24, f = 128, we get;

128 = c/24

c = 128 × 24 = 3,072

Therefore, if the string vibrates 64 times per second, we get;
