Which phrase describes a nonlinear function?

1 answer:

5 0

The only non-linear equation from your choices is the area of a circle as it is:

A=πr^2 and if you take the derivative of A you have:

dA/dr=2πr

So the rate of change changes as r changes, it is not constant thus the function has acceleration, so velocity changes.

This is in contrast to any linear equation which is of the form:

y=mx+b now taking the derivative you see that:

dy/dx=m, now m is a constant value, which means that there is no acceleration and the velocity remains constant.

Is it clockwise rotation or counterclock wise?

If it’s clockwise rotation then C is the answer but if it’s counter lock wise rotation then the answer is A.

Hope this helps!

NEED HELP PLEASE!!!!!!!

If the sales representative is able to get 20% of the prospective customers to subscribe, the maximum expected number of subscriptions per week is 34. If the sales representative earns $3 per subscription in addition to daily wages, the minimum expected value of the extra income per week is $94.20.

For the first answer, refer to the attached solution. Add the data each week, then multiply the sum by 20% to find out which has the maximum expected number of subscriptions.

For the second answer, the minimum expected value in week 2 multiplied by $3 to get the minimum expected value of the extra income in that week.

Answer: just plug in numbers

Step-by-step explanation:

first row

0, 1, 2, 3, 4, 5

so pairs would be

(-3, 0), (-2, 1), (-1, 2), (0, 3), (1, 4), (2, 5)

second row

-5, -3, -1, 1, 3, 5

pairs:

(-3, -5), (-2, -3), (-1, -1), (0, 1), (1, 3), (2, 5)

third row:

-9, -7, -5, -3, -1, 1

pairs:

(-3, -9), (-2, -7), (-1, -5), (0, -3), (1, -1), (2, 1)

fourth row:

-4, -2, 0, 2, 4, 6

pairs:

(-3, -4), (-2, -2), (-1, 0), (0, 2), (1, 4), (2, 6)

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 700

const2013 [10]

Answer:

Z-score for 34-week baby = 0.643

Z-score for 41-week baby = 1.154

Baby weight of 41-week is more than the baby weight of 34-week in the gestation period.

Step-by-step explanation:

Given - Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 700 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 390 grams. If a 34-week gestation period baby weighs 2950 grams and a 41-week gestation period baby weighs 3550 grams

To find - Find the corresponding z-scores. Which baby weighs more relative to the gestation period.

Proof -

Given that,

In between period of 32 to 35 weeks

Mean = 2500

Standard deviation = 700

In between after a period of 40 weeks

Mean = 3100

Standard deviation = 390

Now,

For a 34-week baby,

X = 2950

For a 41-week baby,

X = 3550

Now,

Z-score = (X - mean) / Standard deviation

Now,

For a 34-week baby,

Z - score = (2950 - 2500) / 700 = 0.643

For a 41-week baby,

Z-score = (3550 - 3100) / 390 = 1.154

∴ we get

Z-score for 34-week baby = 0.643

Z-score for 41-week baby = 1.154

As 1.154 > 0.643

So,

Baby weight of 41-week is more than baby weight of 34-week in the gestation period.

Answer:

the cost of labor per hour is $55

Step-by-step explanation:

Let C = cost of labor per hour

Let h = hours worked

Let p = cost of parts

Let t = total price

$c = \frac{t - p }{h} \\\\c = \frac{309.50 - 62}{4.5} \\\\c = \frac{247.50}{4.5} \\\\c = 55$
