4+x/ 4-x Using quotient rule differentiate with respect to x

Is a quadratic sequence (2,3,6,11) arithmetic, geometric, or neither?

Karolina [17]

Answer:

Neither

Step-by-step explanation:

It's neither. The terms do not differ (which means you add the same number to each term) by any constant amount. (Arithmetic)

The terms do not have a common number that you multiply the present term to get the next term. (Geometric)

So this one is neither.

Determine whether the two ratios are proportional. 6/36 and 1/6 a) Yes b) No

Xelga [282]

Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)

A pharmaceutical testing company wants to test a new cholesterol drug. The average cholesterol of the target population is 200 m

Rom4ik [11]

Answer:

The required range is 237.5 to 275.

Step-by-step explanation:

Consider the provided information.

The average cholesterol of the target population is 200 mg and they have a standard deviation of 25 mg.

The the value of μ = 200 and the $\sigma=25$

The company wished to test a sample of people who fall between 1.5 and 3 z-scores above the mean.

Let the value of z is 1.5.

Now use the z score formula: $z=\frac{(x -\mu)}{\sigma}$

Substitute the respective values in the above formula.

$1.5=\frac{(x -200)}{25}$

$37.5=x -200$

$237.5=x$

Now let the value of z is 3.

Substitute the respective values in the z score formula.

$3=\frac{(x -200)}{25}$

$75=x -200$

$275=x$

Hence, the required range is 237.5 to 275.

Terry is skiing down a steep hill. Terry's elevation E(t)

in feet after t seconds is given by E(t) = 2000 − 90t.

Write a complete sentence describing Terry's starting elevation and how it is changing over time.

Terry starts at an elevation of 2000 feet and descends at 90 feet per second.

If the graphs of two linear functions are perpendicular, describe the relationship between the slopes and the y-intercepts.

slope: negative reciprocals of one another.

y-intercept: There is no relationship.

What is the slope of the line on the graph? Enter your answer in the box.

alexira [117]

To find the slope,we can use the slope formula:
$\frac{y1 - y2}{x1 - x2}$
Where x and y are y coordinates and x coordinates respectively.

To find the answer, put any two points into the formula.

In this case, (1,5) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,5), while x2 and y2 would be the x and y coordinate in the first point (0,-1)

$\frac{5 - ( - 1)}{ 1- 0} \\ = \frac{5 + 1}{1} \\ = \frac{ 6}{1} \\ = 6$
Therefore the answer is 6.

Hope it helps!
