Answer:

  97

Step-by-step explanation:

We want to find x when C = 23.

  23 = 0.005x^2 -0.35x +10

  2600 = x^2 -70x . . . . . . subtract 10, multiply by 200

  2600 +35^2 = (x -35)^2 . . . . complete the square

  61.847 +35 = x . . . . . . . square root, add 35 (use the positive result only)

  x ≈ 97 . . . . rounded to integer

The cost is $23 when 97 coolers are produced.

Answer:

y=mx+c

Step-by-step explanation:

A linear equation means the equation of straight line.

The formula for equation of straight line in slope intercept form is y=mx+c

where, m is the slope of line and c is the y intercept

The formula for equation of straight line in double intercept form is x/a+y/b=1

The formula for equation of straight line in normal form is xcos α + y cos α=p

There are more formulas bur assuming you are asking for the general representation of the straight-line equation, it is y=mx+c.

Answer:

[tex]\textbf{Linear Equations : y=mx+b}[/tex]

[tex]\textbf{m= slope}[/tex]

[tex]\textbf{b= y-intercept}[/tex]

[tex]\textbf{Example:-}[/tex] [tex]\textrm{y= 6x+8}[/tex]

Answer:

x-23

Step-by-step explanation:

if the number is x then you want to take 23 away so you have x-23

Answer:

425 or 937

Step-by-step explanation:

First, I listed out all the possible numbers for the first digits, namely, the squares under 10.

1*1=1

2*2=4

3*3=9

Since all the digits have to be different, the first digit cannot be 1 because 1 squared is 1. So that leaves us 4 and 9 to work with, which I tried out one at a time.

Starting with 4:

2 squared is 4.

42

2 times 2 plus 1 equals 5.

425

Starting with 9:

3 squared is 9.

93

2 times 3 plus 1 equals 7.

937

So here we have two numbers that both work and meet the requirements (unless I understood the problem wrong at the part where it says "...the second digit in the 3rd digit on one more than twice the second digit")!

I hope this helped! :D

Answer:

  A)  collinear

Step-by-step explanation:

"Parallel" and "perpendicular" are descriptors of pairs of lines and planes. They do not apply to pairs of points.

The two points have different coordinates, so are distinct, rather than coincident.

Of these words, the only applicable choice is "collinear."

__

Additional comment

Any pair of distinct points is collinear. Two points define a line, and two points on the same line are collinear.

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

If you really mean (4x+4)^1/2, then you have 12^1/2 = 12/2 = 6.

If the exponent is 1/2, it needs to be in parentheses.

The mean, the median and the mode are measures of central tendency, and they are related in some many ways, depending on the type of distribution.

The median of the moderately asymmetrical distribution is 26

The given parameters are:

[tex]Mean = 30[/tex]

[tex]Mode = 24[/tex]

For a moderately asymmetrical distribution, the mean, median and mode are related by the following equation:

[tex]Mode = 3 * Median - 2 * Mean[/tex]

Substitute known values

[tex]30= 3 * Median - 2 * 24[/tex]

[tex]30= 3 * Median - 48[/tex]

Collect like terms

[tex]3 * Median =30+ 48[/tex]

[tex]3 * Median =78[/tex]

Divide both sides by 3

[tex]Median =26[/tex]

Answer:

x = 39

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + x + 12 + 90 = 180

2x + 102 = 180 ( subtract 102 from both sides )

2x = 78 ( divide both sides by 2 )

x = 39

Then

x = 39°

x + 12 = 39 + 12 = 51°
