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:
