A curve has equation y = x
3 − 4x
2 + 2x

Find the x coordinate of each of the points on the curve at which the gradient of the tangent to the
curve is 2

Answers

Answer 1

Answer:

The derivative (or gradient function) describes the gradient of a curve at any point on the curve. Similarly, it also describes the gradient of a tangent to a curve at any point on the curve.

To determine the equation of a tangent to a curve:

Find the derivative using the rules of differentiation.

Substitute the \(x\)-coordinate of the given point into the derivative to calculate the gradient of the tangent.

Substitute the gradient of the tangent and the coordinates of the given point into an appropriate form of the straight line equation.

Make \(y\) the subject of the formula.

The normal to a curve is the line perpendicular to the tangent to the curve at a given point

by name and label all inputs. 1: Saving for Retirement Devon is young and has just graduated college with her associate's degree. She plans to start saving money for retirement as soon as she starts her new job. By taking 10% of her monthly gross income, Devon is able to contribute (a) $ $587 each month to a retirement plan. The account is expected to earn interest with an APR of 5.25% compounded monthly. Round answers to two decimal places. a. How much money will be in Devon's retirement account if she continues to make the same monthly investment for 40 years? (3 pt) I b. Overall, Devon contributed how much of her own money into the retirement account? (4 pt)

Answers

The amount of money in Devon's retirement account if she saves $587 each month for 40 years is $956,488.14.

The total amount of her money contributed is $956,488.14.

What is the value of th retirement account?

The formula that can be used to determine the future value of the retirement account is:

Future value = monthly contribution x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate  = 5.25% / 12 = 0.4375%n = number of years = 40 x 12 = 480

{[(1.004375^480) - 1] / 0.004375} x  $587 = $956,488.14

Total contributions =  $587 x 12 x 40 = $281,760

The average salary for a first-year teacher is $27,989. If the distribution is approximately normal with a standard deviation of $3250. If the z-score is 0.34. What salary corresponds to the z-score

Answers

Answer:  $29,094

If needed, delete the comma and/or the dollar sign.

=========================================================

Work Shown:

mu = 27989 = population mean

sigma = 3250 = population standard deviation

z = (x-mu)/sigma

z*sigma = x-mu

x = z*sigma + mu

x = 0.34*3250 + 27989

x = 29,094

The salary of $29,094 corresponds to the z score of 0.34.

This indicates the salary $29,094 is exactly 0.34 standard deviation units above the mean.

How do I find the value of x??

Answers

Answer:

85

Step-by-step explanation:

The sum of the angles inside a triangle is 180 degrees.

A circle is 360 degrees, making half of it be 180 as well.

Since there are 121 degrees already marked, subtract it from 180 and you will get 59 degrees.

36 + 59 = 95

180 - 95 = 85 degrees.

Answer:

x = 85

Step-by-step explanation:

angles of a triangle = 180 degrees (all angles must equal 180)

if you minus 121 from 180, it will give the interior angle which is 59 degrees

therefore 59 + 36 + x  = 180

to find x plus 59 and 36 = 95 degrees

180 - 95 = 85

x = 85 degrees

The direct material price variance of Saskatewan Can Company will be $6552.

How to calculate the direct material price variance?

From the information given, it should be noted that the direct material price variance will be calculated thus.

Firstly, the actual materials cost will be:

= Actual quantity × Actual price

= 218400 × $0.65

= $141960

The projected materials cost will be:

= 218400 × $0.62

= $135408

Therefore, the price variance will be:

= $141960 - $135408

= $6552

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

we know that in the right triangle ABC

tan function is ratio of opposite side and adjacent side

tan(72°)=h/x

h=xtan(72°) ....... equation 1

In the right triangle ABD

tan(55°)=h/(x+3)

h=(x+3)tan(55°) ..... equation 2

From equation 1 and 2

xtan(72°)=(x+3)tan(55°)

xtan(72°)-xtan(55°)=3tan(55°)

x[tan(72°)-tan(55°)]=3tan(55°)

x=3tan(55°)/[tan(72°)-tan(55°)]

We have to find the value of h

h=xtan(72°)

h=[3tan(55°)*tan(72°)]/[tan(72°)-tan(55°)]

h=8 miles

Hence, the height is 8 miles of the plane.
