When you go swimming the pressure in your ears varies directly with the depth at which you swim. At 10 feet, the pressure is about 4.3 pounds per square inch (psi). a) Write the variation function. b) Predict the pressure at 50 feet. c) It is unsafe for amateur divers to swim where the pressure is more than 65 psi. How deep can an amateur swimmer safely swim (round to the nearest thousandth)

Answers

Answer:

(a) [tex]p = 0.43d[/tex]

(b) [tex]p = 21.5[/tex]

(c) [tex]d = 151.163[/tex]

Step-by-step explanation:

Given

Variation: Direct

Represent ear pressure with p and depth with d.

So, we have:

[tex]p\ \alpha\ d[/tex]

[tex]d =10[/tex] when [tex]p =4.3[/tex]

Solving (a): Write a variation

We have:

[tex]p\ \alpha\ d[/tex]

Write as an equation

[tex]p = kd[/tex]

Where: k is the constant of variation

[tex]d =10[/tex] when [tex]p =4.3[/tex]

So, we have:

[tex]4.3 = k * 10[/tex]

Make k the subject

[tex]k = \frac{4.3}{10}[/tex]

[tex]k = 0.43[/tex]

Substitute 0.43 for k in [tex]p = kd[/tex]

[tex]p = 0.43d[/tex]

Solving (b): Pressure at 50 feet

Substitute 50 for d in [tex]p = 0.43d[/tex]

[tex]p = 0.43 * 50[/tex]

[tex]p = 21.5[/tex]

The pressure is 21.5 pounds per square

Solving (c): The safe depth

The safe depth stops at a pressure of 65psi.

Substitute 65 for p in [tex]p = 0.43d[/tex]

[tex]65 = 0.43 * d[/tex]

Make d the subject

[tex]d = \frac{65}{0.43}[/tex]

[tex]d = 151.162790698[/tex]

[tex]d = 151.163[/tex] -- approximated

The safe distance for an amateur is 151.163ft

Solve the following system of
equations:
x = 3y + 4
3x - 5y = 8

Answers

You plug in the x = 3y+4 into the 3x part of 3x -5y=8. You distribute the 3 and add like terms to end up with 4y=12. You divide by 4 to get y alone and get -1. That’s your y value. You plug that -1 into the y part of any of the two equations to find x. The simplest one is to plug it in to x=3y+4, and you get -3+4=x, so x= -1

Find the slope and y-intercept of y – 3x = 2

Answers

Answer:

slope is 3/1 y=2

Step-by-step explanation:

Slope: 3
Y-intercept: 2

Slope-intercept form can be represented as y=mx+b. The m is the slope and the b is the y-intercept. To get the equation into y=mx+b, add 3x to both sides to get the y by itself. When you add 3x to both sides you will get y=3x+2. The slope will be 3 because the 3 is in place of the m. The y-intercept is 2 because the 2 is in the place of the b.

chapter 13 medical math assignment sheet cengage learning a dental laboratory technician (DLT) earns $14 per hour when she works days and $18 per hour when she works nights. One month she works six 4-hour days, three 8-hour days, three 10-hour days, five 6-hour nights, and four 8-hour nights. What is her total pay for the month

Answers

Answer:

$2,208

Step-by-step explanation:

In order to calculate her total pay for the month we simply need to use the hours provided in the question, multiply each amount of hours by they pay rate for that day/night. Finally, we add all of the products together to get the final pay for the month.

6 * (4*14) = 336

3 * (8 * 14) = 336

3 * (10 * 14) = 420

5 * (6 * 18) = 540

4 * (8 * 18) = 576

336 + 336 + 420 + 540 + 576 = $2,208

Finally, we can see that her total pay for the month is $2,208

the quotient of 12 and the product of 4 and 5 as a numerical expression.

Answers

Answer:

Step-by-step explanation:

The "product of 4 and 5" is (4)(5).                                  12

The quotient of 12 and the product of 4 and 5 is   ------------

                                                                                         (4)(5)

The numerical expression for the given phrase is 12/(4×5).

What is a quotient?

In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

The given phrase is the quotient of 12 and the product of 4 and 5.

Now, 12/(4×5)

= 12/20

= 3/5

= 0.6

Therefore, the numerical expression is 12/(4×5).

The product of (a − b)(a − b) is a perfect square trinomial.

A. Sometimes
B. Always
C. Never

Answers

Answer:

Always.

Step-by-step explanation:

Answer:

Always

Step-by-step explanation:

The first term of the product is always the first term of the original binomial squared.

The middle term of the product is always negative and equal to twice the product of the first and last terms of the original binomial.

The last term of the product is always positive and equal to the last term of the original binomial squared.

EX: Find the product of (3x − 4)2.

Identify what a and b are in the given binomial. Here, a is equal to 3x and b is equal to 4.

(3x − 4)2

substitute a for 3 times x and substitute b for 4 a     b

Now, substitute the values for a and b into a2 − 2ab + b2.

a2 − 2ab + b2

Make sure you place the term in parentheses when it involves more than one factor. Then, use the Power of a Product rule to simplify.

(3x)2 − 2(3x)(4) + (4)2

32x2 − 24x + 16

9x2 − 24x + 16
