Answer:

The amount of time it takes to ride 26 miles is 2.89 hours.

Step-by-step explanation:

Given : You ride your bike at 9 miles per hour.

To find : How long it will take you to ride 26 miles ?

Solution :

The equation given is 9\times t=26

Using distance formula,

\text{Distance}=\text{Speed}\times \text{Time}

According to formula t represent the time taken to cover the distance.

Your speed in miles per hour is 9 miles per hour.

The number of miles you've traveled so far is 26 miles.

Solving the equation,

9\times t=26

t=\frac{26}{9}

t=2.89 hours

The amount of time it takes to ride 26 miles is 2.89 hours.

aksik [14]

Both the domain and range of the transformed function are the same as those of the parent function.

Option A is the correct answer.

The complete question is

Both the domain and range of the transformed function are the same as those of the parent function.

Neither the domain nor the range of the transformed function are the same as those of the parent function.

The range but not the domain of the transformed function is the same as that of the parent function.

The domain but not the range of the transformed function is the same as that of the parent function

<h3>What is a function ?</h3>

A function is a mathematical statement which defines relationship between a dependent variable and an independent variable.

It is given that

f(x) = |x|

The graph is plotted

When the graph is is reflected across the y-axis and translated to the left 5 units.

When reflected across y axis , g(x) = |-x| = |x|

When translated 5 units to the left , g(x) = |x+5|

Both the graph is plotted and attached with the answer

The domain is the any value that can be an input in the function

domain for both the function is {x≥0}

The range is the value of the function that exists at any given time {y≥0}

From the option given

Both the domain and range of the transformed function are the same as those of the parent function.

Option A is the correct answer.

Laura fills a bucket with water at a rate of 6 L/min. At the same time, Sarah empties a bucket holding 30 L of water at a rate o
Mice21 [21]
0+6 L per min
30-9 L per min
so let x represent the time
0+6 times x and
30-9 times x
we want to know what time they will be equal so set them equatl to each other
0+6x=30-9x
6x=30-9x
add 9x to both sides
15x=30
divide both sides by 15
x=2
at 2 mins, they will be equal
find out what that is
subsitute in 0+6x
0+6(2)=0+12=12L

the answers are 2 minutes and 12 liters respectively

The manager of a pizza chain in Albuquerque, New Mexico, wants to determine the average size of their advertised 20-inch pizzas.
7nadin3 [17]

Answer:

The sample must be of at least 48 pizzas.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

How large a sample must she take if she wants the margin of error to be under 0.5 inch?

She needs a sample of at least n, in which is found when M = 0.5, \sigma = 2.1

M = z*\frac{\sigma}{\sqrt{n}}

0.5 = 1.645*\frac{2.1}{\sqrt{n}}

0.5\sqrt{n} = 2.1*1.645

\sqrt{n} = \frac{2.1*1.645}{0.5}

(\sqrt{n})^{2} = (\frac{2.1*1.645}{0.5})^{2}

n = 47.73

Rounding up

The sample must be of at least 48 pizzas.
