The rate of the boat that travels 66 miles in 2 hours is approximately 2904 feet per minute.

Given:

Distance traveled = 66 miles

Time taken = 2 hours

We know that:

1 mile =  5280 feet

66 miles = 66 [tex]\times[/tex] 5280

                  348,480 feet

Next, we'll convert the time from hours to minutes.

 1 hour = 60 minutes,

2 hours = 120 minutes

Now, we can calculate the rate in feet per minute:

Rate (feet per minute) =  [tex]\dfrac{ Distance \ in\ feet}{Time\ in\ minutes}[/tex]

                    Rate             =        [tex]\dfrac{348480}{120}[/tex]

Rate   ≈ 2904 feet per minute

So, the rate of the boat is approximately 2904 feet per minute.

Answer:

First of all, each slice represents an intersecting plane at that level.

For example, y = 2 is a plane that passes thorugh that level and cuts the volume given by [tex]x^{2} -y^{2}+z^{2}=2[/tex]

We replace this value in the given volume.

[tex]x^{2} -y^{2}+z^{2}=2\\x^{2} -(2)^{2}+z^{2}=2\\x^{2}+z^{2}=2+4\\x^{2}+z^{2}=6[/tex]

The first five non-zero multiples of 5 are 5, 10, 15, 20, and 25. These are obtained by multiplying the number 5 by the integers 1 to 5. All non-zero multiples of 5 will end with the digit 5 or 0, confirming their divisibility by 5.

Identifying Non-Zero Multiples of 5

When you're looking for non-zero multiples of 5, it's important to remember that the basic property of a multiple of 5 is that it ends in either 0 or 5. However, since we're focusing on non-zero multiples, we will exclude any multiples that end in zero. A multiple of a number is obtained by multiplying that number by an integer. For the number 5, the first five non-zero multiples are 5, 10, 15, 20, and 25. Notice that these numbers are the result of multiplying 5 by the integers 1 through 5, respectively.

Understanding that the concept of multiples relates to a number being multiplied by a sequence of whole numbers or integers gives us the ability to identify patterns within these numbers. For example, all non-zero multiples of 5 will end with the digit 5 or 0, reinforcing the idea that if a number ends in 5, it is divisible by 5 without remainder. This concept is supported by empirical observation and the understanding that patterns and numbers, such as these, can offer insight into broader mathematical ideas. Furthermore, the significance of the number 5 in various mathematical circumstances, such as the number of digits in a number or the properties of multiples, is apparent throughout different contexts.

Step-by-step explanation:

Given : The sequence 15, 13, 11, 9,....

We have to determine the equation that can be used to find the tenth term of the given sequence 15, 13, 11, 9,....

Consider the given sequence 15, 13, 11, 9,..

[tex]a_1= 15, a_2=13, a_3= 11[/tex]

Answer:

The scientific notation 2.15 × 10-3 has a value of

0.00215

Step-by-step explanation:

Step one

This problem bothers conversion from standard form otherwise known as scientific notation to decimal form

Step two

Now we are presented with the expression

2.15 × 10-³

To convert this it is equivalent to

2.15/10³= 2.15/1000

= 0.00215

On the other hand this can also be achieved without calculations by visually counting from the decimal point to the right 2 placements before inserting the first integer

This method saves alot of time expecialy when time is of essence.

Hence the scientific notation 2.15 × 10-3 has a value of

0.00215

To write the expression 4 log x − 6 log (x + 2) as a single logarithm, apply the properties of logarithms.

To write the expression 4 log x − 6 log (x + 2) as a single logarithm, we can make use of the following logarithmic properties:

Using these properties, we can simplify the given expression as follows:

4 log x − 6 log (x + 2) = log(x^4) - log((x + 2)^6)

Therefore, the expression can be written as the single logarithm log(x^4) - log((x + 2)^6).

2.a.  8x + y = -18 the standard form of the equation.

A line has no definite length it can extend in both the directions indefinitely.

According to the given question a functions f(x) = 5x + 1 is given and we have to find the value of this function when x = -4.

Given f(x) = 5x + 1

f(-4) = 5(-4) + 1

f(-4) = -20 + 1

f(-4) = -19.

In the second question we have to write an equation of the line passing through the point (-2,-2) with slope -8.

We know equation of a line in slope intercept form is y = mx + b.

∴ -2 = (-8)(-2) + b

  -2 = 16 + b

   b = - 18.

So, y = -8x -18 OR 8x + y = -18.

Answer: Segment, line, ray

Step-by-step explanation: too answer was confusing and point was wrong.

The answers are a. ray, e. segment and f. line

In geometry, a one-dimensional figure has only length and no other dimensions such as width or height. Let's analyze each option:

Thus, the one-dimensional figures are the ray, segment, and line.

The dilation of a rectangle with a scale factor of 4 will result in each side of the rectangle being multiplied by 4, thus the perimeter will also be quadrupled.

When a rectangle undergoes a dilation with a scale factor of 4, the lengths of all sides of the rectangle are multiplied by 4. Since perimeter is the sum of all the side lengths of a rectangle, the perimeter will also be affected by the scale factor. Therefore, if the original perimeter of the rectangle is P, the new perimeter after dilation will be 4 × P.

Using the property of dilations, the new dimensions of the rectangle will be proportional to the original dimensions. For example, if the original length l and width w of the rectangle are scaled by a factor of 4, the new dimensions will be 4l and 4w respectively. Subsequently, the new perimeter will be 2(4l + 4w) which is the same as saying 4 × (2l + 2w), proving the perimeter is scaled by the same factor of 4.

The function t(n)=8n represents the number of tires needed for each truck. By substituting n=25 into the function, we find we need 200 tires for 25 trucks.

The function that represents the number of tires needed for each truck is t(n) = 8n. This means for each truck we need 8 tires, as n is the number of trucks and 8n signifies the total number of tires needed for those trucks.

If we want to find out the number of tires we would need for 25 trucks, we substitute n = 25 into the function, yielding t(25) = 8 * 25. When you perform this multiplication, the result is 200 tires.

So, for 25 trucks we would need 200 tires. Meaning "the correct answer is C. 200 tires".

Final answer:

To find the x-coordinates where the function f(x)=6sin(x)-sin^2(x) has a horizontal tangent line, we calculate the derivative, set it equal to zero, and solve for x, using trigonometric identities and potentially numerical methods. Thus, the solutions for \( x \) in the interval [tex]\( [0, 2\pi] \) are \( x = \frac{\pi}{2} + k\pi \), where \( k \)[/tex] is an integer. These solutions represent the points where [tex]\( \cos(x) = 0 \)[/tex], causing the equation to be satisfied.

Explanation:

The question asks to find the x-coordinates of all points on the graph of the function f(x)=6sin(x)-sin2(x) at which the tangent line is horizontal. To find these coordinates, we need to look for points where the derivative of the function is equal to zero since a horizontal tangent line has a slope of zero.

We start by finding the derivative of the function:

f'(x) = d/dx[6sin(x)-sin2(x)]

f'(x) = 6cos(x)-2sin(x)cos(x)

f'(x) = 6cos(x)-sin(2x) (using the double angle identity sin(2x)=2sin(x)cos(x))

To find when the derivative is zero, we set the derivative equal to zero:

0 = 6cos(x) - sin(2x)

We then need to solve this equation for x. This involves using trigonometric identities and potentially numerical methods if the equation cannot be solved analytically. The x-coordinates will be the solutions to this equation within the domain for which we are interested, typically 0 to 2π for one full cycle of a trigonometric function.

To solve the equation [tex]\( 0 = 6\cos(x) - \sin(2x) \)[/tex], we'll first try to rewrite it in terms of a single trigonometric function using known identities.

The double angle identity for sine states that [tex]\( \sin(2x) = 2\sin(x)\cos(x) \)[/tex]. Substituting this identity into the equation, we get:

[tex]\[ 0 = 6\cos(x) - 2\sin(x)\cos(x) \]\\Now, let's factor out \( \cos(x) \):\[ 0 = \cos(x)(6 - 2\sin(x)) \][/tex]

Now, for the equation to be true, either [tex]\( \cos(x) = 0 \) or \( 6 - 2\sin(x) = 0 \)[/tex].

1. If [tex]\( \cos(x) = 0 \), then \( x = \frac{\pi}{2} + k\pi \)[/tex], where \( k \) is an integer.

2. If [tex]\( 6 - 2\sin(x) = 0 \), then \( \sin(x) = 3 \)[/tex]. However, the sine function has a range of \([-1, 1]\), so there are no solutions for \( x \) in this case.

Thus, the solutions for \( x \) in the interval [tex]\( [0, 2\pi] \) are \( x = \frac{\pi}{2} + k\pi \), where \( k \)[/tex] is an integer. These solutions represent the points where [tex]\( \cos(x) = 0 \)[/tex], causing the equation to be satisfied.
