The ocean rises and falls each day due to tides. The Bay of Fundy in Canada has some of the highest tides in the world.Its tidew
svp [43]

Answer:

y(x)=53.478\sin\left(4\pi\ x\right)

where x is the number of days and y is the total fall and rise in the tides.

Step-by-step explanation:

We are given the following in the question:

In one day, the tide rises twice and falls twice.

Rise in tides given by R,

R = 53.478 feet

Fall in tides given by F,

F = 53.478 feet

Total rise in tide in 1 day =

2\times R = 2\times 53.478 = 106.956\text{ feet}

Total fall in tide in 1 day =

2\times F = 2\times 53.478 = 106.956\text{ feet}

The fall and rise in the tides can expressed with the function:

y(x)=53.478\sin\left(4\pi\ x\right)

where y is the total fall and rise in tides and x is the number of days.

The attached image shows the graph for the cycle of tides.

Putting x = 1 for 1 day, we have,

y(1)=53.478\sin\left(4\pi\ (1)\right) = 0

Thus, total fall and rise in 1 day is 0 feet.

If R is between P and Q, find the value of x and PR. PQ=17, PR=5x+2, RQ=x^2-1
vodka [1.7K]

The value of x will be2.217 and PR will be 13.085 units.

<h3>What is a line segment?</h3>

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given that,

Line PQ consists of two segments PR and RQ

So,

PQ = PR + RQ

17 = 5x+2 + x² - 1

x² + 5x  - 16 = 0

The roots of the equation will be

x = [-5 + √(25 + 64) ] ÷ 2

x = 2.217

Now,

PR = 5(2.217) + 2 = 13.085

Hence "The value of x will be2.217 and PR will be 13.085 units".
