Answer:

He rented the bike for 5 hours.

Step-by-step explanation:

Fixed rate for renting a bike is $8 and rate per hour for renting is $5.

Amount paid by Jermaine is $33.

To find the hourly rent amount that he paid, subtract the fixed rate ($8) from total amount $33.

Rent amount for the bike = 33 - 8

                                          = $ 25

Number of hours rented = 25 ÷ 5

The value is approximately equal to 12.0711°

While measuring angles, we use various units of measurements such as the degrees or the SI unit radians as per our convenience.

When we use the degree system, we can use the degree-minute-second or the degree decimal system as per our requirement of precision.

The angle in degree - minutes - seconds is 12°4'16"

We know that [tex]\frac{1}{60}[/tex] of a degree is minute and [tex]\frac{1}{60}[/tex] of a minute is a second.

Hence, [tex]\frac{1}{3600}[/tex] of a degree is a second.

Therefore the angle [tex]\theta[/tex] in degrees and decimal fractions of degrees will be:

[tex]\theta[/tex] = [tex]12+\frac{1}{60}[/tex] × 4 + [tex]\frac{1}{3600}[/tex] × 16

According to the empirical rule, the observations in a data set that can be reasonably approximated by a normal curve lie within two standard deviations of the mean is 95% .

The empirical rule, also known as the 68-95-99.7 rule or the three-sigma rule, is a statistical guideline that describes the approximate distribution of data that can be reasonably approximated by a normal curve. The rule states that:

Approximately 68% of the data falls within one standard deviation of the mean.

Approximately 95% of the data falls within two standard deviations of the mean.

Approximately 99.7% of the data falls within three standard deviations of the mean.

In other words, if a set of data is normally distributed (meaning it follows a bell-shaped curve), we can use the empirical rule to estimate the proportion of the data that falls within a certain range of values.

For example, let's say we have a data set that has a mean of 50 and a standard deviation of 10. Using the empirical rule, we can estimate that approximately:

68% of the data falls between 40 and 60 (one standard deviation from the mean)

95% of the data falls between 30 and 70 (two standard deviations from the mean)

99.7% of the data falls between 20 and 80 (three standard deviations from the mean)

Let the smaller polygon have side lengths a and the larger polygon have side lengths b. Since the polygons are similar, the ratio of corresponding side lengths is the same as the ratio of their areas. That is:

b^2 / a^2 = 128 / 98

Simplifying this expression, we get:

b / a = √(128 / 98) = √(64 / 49) = (8 / 7)

Now we can use the fact that the perimeter of the smaller polygon is 42 inches:

4a = 42

a = 10.5

Substituting this into the ratio we found above, we get:

b = (8 / 7) * a = (8 / 7) * 10.5 = 12

Therefore, the larger polygon has a perimeter of:

The formula for Average Fixed Cost (AFC) is: AFC = FC / Q. Where FC represents the total fixed costs incurred by a firm and Q represents the quantity of output produced by the firm.

AFC is a per-unit measure of the fixed cost of production, and represents the amount of fixed cost that is attributed to each unit of output. As the quantity of output increases, the AFC decreases, since the fixed costs are spread out over a larger number of units. AFC is an important concept in economics and business, as it is used to calculate other cost measures such as average total cost and average variable cost.

Answer: The function has three x-intercepts.

Step-by-step explanation:

To find the x-intercepts of a function, we need to find the values of x for which the function equals zero.

So, to find the x-intercepts of the function:

F(x) = (x+5)^3(x-9)(x-1)

We need to solve the equation:

F(x) = 0

We can see that the function will be equal to zero when any of the factors on the right-hand side is equal to zero. Therefore, we need to solve the following four equations:

(x+5) = 0, which gives x = -5

(x-9) = 0, which gives x = 9

(x-1) = 0, which gives x = 1

(x+5)^3 = 0, which gives x = -5

The last equation, (x+5)^3 = 0, has a triple root at x = -5, since the factor (x+5) appears three times. Therefore, there are a total of three x-intercepts for the function:

x = -5 (with multiplicity 3), x = 1, and x = 9.

The width of the rectangular box is W = 8 inches

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the volume of the rectangular box be V = 264 inches³

Let the height of the rectangular box be H = 3 inches

Let the length of the rectangular box be L

Let the width of the rectangular box be W

Now , L = 3 + W

And , Volume of Rectangle = Length x Width x Height

Substituting the values in the equation , we get

264 = 3 x ( W ) x ( 3 + W )

On simplifying the equation , we get

Divide by 3 on both sides of the equation , we get

3W + W² = 88

Subtracting 88 on both sides of the equation , we get

W² + 3W - 88 = 0   be equation (1)

On factorizing the equation , we get

W² + 11W - 8W - 88 = 0

Taking the common factors of the equation , we get

W ( W + 11 ) - 8 ( W + 11 ) = 0

On further simplification , we get

( W - 8 ) ( W + 11 ) = 0

The width cannot be negative , so

( W - 8 ) = 0

Adding 8 on both sides , we get

Answer:

26.6°

Step-by-step explanation:

An angle is a measure of a turn, measured in degrees or °. Angles are made up of two rays, making the sides of the angle.

There are right angles (exactly 90 degrees), acute angles (less than 90 degrees), obtuse angles (more than 90 degrees), and reflex angles (more than 180 degrees).

If we know that the angle shown is a right angle, we also know that a right angle is equal to 90°. To solve for the value of c, we can use this equation:

Therefore, the value of c is 26.6°.

The length of the missing side of the quadrilateral shown if the perimeter is 5x+3 and sides are 8x-4 and 10x+7 and 3x+6 is -16x+12.

This is defined as the total distance around the shape.

The perimeter is the sum of the 4 sides.

Adding , 8x-4 and 10x+7 and 3x+6 , we have:

8x-4 + 10x+7 + 3x+6  = 21x+9

Subtract that from the given perimeter to get the missing side length which is:

The required rate of change of f(x) from x = -6 to x = 3 is f'(x) = 7.

Rate of change is defined as the change in value with rest to another value is called rate of change.

Here,
Given that,
f(x) = x² + 4x -15

Now, put x = -3
f(-3) = 9 - 12 - 15
f(-3) = -18

Now put x = 6
f(6)= 36 + 24 - 15
f(6) = 45

Since we know that, the rate of change of function is given as,
f'(x) = f'(a) - f'(b) / a -b

f'(x) =f'(6) - f'(-3) / a - b

f'(x) = 45 - (-18) / 6 -(-3)
f'(x) = 63 / 9
f'(x) = 7

In MATLAB, you can convert a string to an integer using the str2double() or str2num() function. Both functions convert a string to a double-precision floating-point number, but str2num() also supports the conversion of strings to other numeric data types.

Here's an example of how to convert a string to an integer using str2double():

str = '123';  % string to convert to integer

num = str2double(str);  % convert the string to a double-precision number

int = int32(num);  % convert the double-precision number to a 32-bit integer

In this example, the str variable contains the string '123', which we want to convert to an integer. We first use the str2double() function to convert the string to a double-precision number, which we then convert to a 32-bit integer using the int32() function.

Alternatively, you can use the str2num() function to convert the string directly to an integer:

str = '123';  % string to convert to integer

int = int32(str2num(str));  % convert the string to a 32-bit integer

In this example, we use the str2num() function to convert the string directly to a 32-bit integer, and then assign the result to the int variable.

It is important to note that if the string cannot be converted to a number, both functions will return NaN (Not a Number). Additionally, if the string represents a number that is too large to be represented by an integer, the result will be rounded or truncated.

The statement "If f is differentiable at a, then f is continuous at a" is true, but "If f is continuous at a, then f is differentiable at a" is false.

Differentiability and continuity are two important concepts in calculus. A function is said to be continuous at a point if the values of the function approach a finite limit as the independent variable approaches the same value. In other words, there are no sudden jumps or breaks in the function at that point.

On the other hand, a function is said to be differentiable at a point if the limit of the rate of change of the function exists as the independent variable approaches the same value. This rate of change is called the derivative of the function and it is used to determine the slope of the function at that point.

So, it is true that if a function is differentiable at a point, then it is also continuous at that point. In other words, a continuous function must be differentiable. However, the reverse is not necessarily true. A function can reach a point where it is continuous but not differentiable. For example, the absolute value function is continuous everywhere but it is not differentiable at x = 0.

Therefore, we can say that if f is differentiable at a, then f is continuous at a. But if f is continuous at a, it does not imply that f is differentiable at a.
