The eastern continental trail is 15 times longer than the Erie canal way trail. The combined length of the hiking trails is 5,76
Lena [83]

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

Step-by-step explanation:

Given,

Combined length of both trails = 5760 miles

Let,

x be the length of eatern continental trail.

y be the length of Erie canal trail.

According to given statement;

x+y=5760     Eqn 1

x = 15y          Eqn 2

Putting value of x from Eqn 2 in Eqn 1

15y+y=5760\\16y=5760

Dividing both sides by 16

\frac{16y}{16}=\frac{5760}{16}\\y=360\\

Putting y=360 in Eqn 2

x=15(360)\\x=5400

The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.

Which graph is an example of a function whose parent function is y=sqrt x?
hoa [83]

See in the explanation

<h2>Explanation:</h2>

Hello! Recall that you have to post complete questions in order to get excellent and correct answers. Since you have missing graphs, I can't say what is the correct option. However, I'll try to help you about the concept of parent functions.

A parent function is the most basic function that shares the same characteristics with other complicated functions. One of the parent function in mathematics is the Square Root Function written as:

y=f(x)=\sqrt{x}

This parent function is shown in the First Figure below. As you can see:

  • The domain is the set of all real numbers greater (or equal) than zero
  • The range is the set of all real numbers greater (or equal) than zero

An example of a function whose parent function is f(x)=\sqrt{x} is the same function translated three units to the left. In a mathematical language:

g(x)=\sqrt{x+3}

This graph is shown in the second figure. As you can see, these two graph share the same characteristics. The only difference is a translation performed on the second one. For the second graph, we have:

  • The domain is the set of all real numbers greater (or equal) than -3
  • The range is the set of all real numbers greater (or equal) than zero

Find the slope using the formula.<br> (3,-2) and (3, 6)
dangina [55]

Answer:

m = undef

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (3, -2)

Point (3, 6)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{6+2}{3-3}
  2. Add/Subtract:               m=\frac{8}{0}
  3. Divide:                          m = undef

When we divide anything by zero, we will get undefined. Therefore, this would be a vertical line.

Write the following expression. The quantity 81 minus 5k, squared
Stella [2.4K]

Answer:

81-25k²

Step-by-step explanation:

We need to write the expression for "The quantity 81 minus 5k, squared".

Square of any number x is given by x².

Square of 5k is given by : (5k)²= 5²×k²=25k²

Now subtract 25k² from 81.

It means we get : 81-25k². It is required expression.
