What should the mean diameter, in inches, be in order to minimize the fraction of bearings that are scrapped?

The rate of change is D. 1foot 5inches (17inches) 8inches.

The foot is a measure of a unit of length (or distance) in US units, which equals 12 inches.

The rate of change is the difference between x and y variables.  It can be mathematically expressed as ​Change in input/​Change in output​​.  The formula for the rate of change is as follows:

= ​Δx/Δy

where Δ = change

14inches + 8inches = 22inches

13inches + 7.5inches = 20.5inches

18inches + 8inches = 26inches

But 17inches + 8inches = 25inches

Find the rate of change from 2feet 1 inch (25inches) to 8inches.

Thus, the rate of change is D. 1foot 5inches (17inches) 8inches.

Answer:

The answer is the first one.

Step-by-step explanation:

Okay, so the first one is solved like this:

You do 360*30%. 30% is 0.3 in decimal form. So 360*0.3=108. 108 is the amount that is discounted, NOT the price. You have to do 360-108, which is 252. The discounted price is $252.

Now the second one is solved like this:

You do 360*10% FIRST because the problem says it was marked 10% BEFORE the 20%. 10%=0.1, so 360*0.1=36. You subtract 360-36, which is 324. Then, you multiply 324 by 20% or 0.2, to get 64.8, which is the discount of 20%. You subtract 324-64.8, which is $259.20. So the first one is the answer because it is cheaper since 252 is less than 259.20. If you need this explanation, don't use this word for word. Summarize this in YOUR own words!

He should by the first washing machine because it cost less than the second washing machine.

Answer:

Number of Uni Cycles = 7

Number of Bi Cycles = 26

Number of Uni Cycles = 39

Total Wheels = 98

Total Seats = 46

Step-by-step explanation:

Uni Cycles consist of 1 wheel

7 x 1 = 7 wheels

Bi Cycles consist of 2 wheels (twice than tri cycle)

26 x 2 = 52 wheels

Tri Cycles consist of 3 wheels

13 x 3 = 39 wheels

Total seats = 7 + 26 + 13 = 46

Total wheels = 7 + 52 + 39 = 98

The number of cycles is given below:-

Number of Uni Cycles = 7

Number of Bi Cycles = 26

Number of Uni Cycles = 39

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Total Wheels = 98

Total Seats = 46

Uni Cycles consist of 1 wheel

7 x 1 = 7 wheels

Bi Cycles consist of 2 wheels (twice as tricycle)

26 x 2 = 52 wheels

Tri Cycles consist of 3 wheels

13 x 3 = 39 wheels

Total seats = 7 + 26 + 13 = 46

Total wheels = 7 + 52 + 39 = 98

Answer: 3,4,5,6 can be the complete list for the f(x).

Step-by-step explanation:

Given a polynomial function f(x) which is a fourth degree polynomial .Therefore it must has 4 roots.

Let's check all the options for the possible list of roots of f(x)

1) 3,4,5,6 can be the complete list for the f(x) .

Option 2) and option 3) cannot be the complete list for the f(x) as it has one complex root and complex roots occur in pair.

Option 4) cannot be the complete list for f(x) as complex roots occur in pair and they conjugates but conjugate of 5+i is 5-i(which is not given) not -5+i

Answer:

x¹= -4 , x²= 7

Step-by-step explanation:

1) Determine the defined range

¼x-¾=7/x =/ 0

2) Move the expression to the left-hand side and change its sign

[tex] \frac{1}{4} x - \frac{3}{4} - \frac{7}{x} = 0 \\ \\ [/tex]

3) Write all numerators above the least common denominator 4x

[tex] \frac{ {x}^{2} - 3x - 28 }{4x} = 0[/tex]

4) When the quotient of expressions equals 0, the numerator has to be 0

x²-3x-28=0

5) Write -3x as a difference

x²+4x-7x-28=0

6) Factor out x from the expression

x(x+4)-7x-28=0

7) Factor out -7 from the expression

×(x+4)-7(x+4)=0

8) Factor out x+4 from the expression

(x+4)×(x-7)=0

9) When the product of the factors equals 0, at least one factor is 0

x+4=0

x-7=0

10) Solve for the x

x+4=0 -> x= -4

x-7=0 -> x=7

11) Check if the solution has defined range

x= -4

x=7

12) The solution has 2 solutions

[tex]x1 = - 4 \: \: x2 = 7[/tex]

L=12m

A/L=W

(188/12) meters=W=47/3

P=2W+2L

P=2(12m) + 2(47/3 m)

= 24 + 94/3 meters

Pretty easy when u know what you're doing

Use trigonometry to solve for x.

The tangent function is defined to be opposite side divided by the adjacent side.

tan(78) = x/10

tan(78)(10) = x

47.0463010948 = x

We now round off to two decimal places. In other words, we round off to the nearest tenths.

47.05 = x
