The equation of the line tangent to the graph of f defined by g(x) = 4x^3 - 5x + 3 at the point where x = -1 is y = 7x + 11

Given the function of the graph defined as gx) = 4x^3 - 5x + 3.

If x = -1

f(-1) = 4(-1)^3 - 5(-1) + 3.

f(-1) = 4(-1) + 5 + 3

f(-1) = -4 + 8

f(-1) = 4

Hence the coordinate point on the line will be (-1, 4)

Get the slope of the line at x = 1

\(m=\frac{dy}{dx} = 12x^2-5\\m=12(-1)^2-5\\m=12-5\\m=7\)

Get the required equation. The equation of the line in point-slope form is expressed as \(y-y_0=m(x-x_0)\)

\(y-4=7(x+1)\\y-4=7x+7\\y=7x+7+4\\y=7x+11\\\)

Hence the equation of the line tangent to the graph of f at the point where x = -1 is y = 7x + 11

Based on the given conditions, Jane has $31, Kevin has $25, and Hans has $50 in their wallets.

Let's solve the problem step by step.

First, let's assume that Jane has X dollars in her wallet. Since Kevin has $6 less than Jane, Kevin would have X - $6 dollars in his wallet.

Next, we're given that Hans has 2 times what Kevin has. So, Hans would have 2 * (X - $6) dollars in his wallet.

According to the information given, the total amount of money they have in their wallets is $106. We can write this as an equation:

X + (X - $6) + 2 * (X - $6) = $106

Simplifying the equation:

4X - $18 = $106

4X = $124

X = $31

Now we know that Jane has $31 in her wallet.

Substituting this value into the previous calculations, we find that Kevin has $31 - $6 = $25 and Hans has 2 * ($25) = $50.

To find the total amount they have, we sum up their individual amounts:

Jane: $31

Kevin: $25

Hans: $50

Adding these amounts together, we get $31 + $25 + $50 = $106, which matches the total amount stated in the problem.

The conclusion that can be drawn from Jimmy's income with the change in insurance is that Jimmy's net income would decrease.

When expenses rise, net income will decrease. Net income is calculated by subtracting expenses from gross income, so if expenses increase, the amount of net income will decrease.

This means that with the increase in insurance by $ 50, Jimmy can expect that his net income would decrease by a total amount of $ 50 which is the amount the insurance increased by.

The required triangle KLM and triangle QPR has been proved congruent with Hypotenuse-Leg theorem.

In a right angled triangle, its side, such as hypotenuse, perpendicular and base  is Pythagorean triplets.

From triangle KLM and QPR,

The original point was before reflection was (4,3)

Reflection is a geometrical transformation of a shape where by the coordinates of points that make the shape are moved over a line of reflection.

The resultant effect of reflection is always a mirror image of what the shape was before.

If the reflected point of the shape is (4, -3) and it is reflected over the x-axis, then the line of reflection is x = 0

When a point is reflected over the x -axis, the x-coordinated is unaffected only the y-coordinate will change.

The direct opposite of -3 reflected over x= 0 is 3.

Therefore the coordinates of the point reflected over the x-axis are (4, 3)

Answer: 21

Step-by-step explanation:

To find this value, we first convert the percentage to a decimal by dividing it by 100: 15/100 = 0.15. We then multiply this decimal by the given number, 140, to find the value of 15% of 140: 0.15 * 140 = 21.

In a rectangle WXYZ, if the measure of angle 1 is 30 degrees, then the measure of angle 8 can be determined.

A rectangle is a quadrilateral with four right angles. In a rectangle, opposite angles are congruent, meaning they have the same measure. Since angle 1 is given as 30 degrees, angle 3, which is opposite to angle 1, also measures 30 degrees.

In a rectangle, opposite angles are congruent. Since angle 1 and angle 8 are opposite angles in quadrilateral WXYZ, and angle 1 measures 30 degrees, we can conclude that angle 8 also measures 30 degrees. This is because opposite angles in a rectangle are congruent.
Since angle 3 and angle 8 are adjacent angles sharing a side, their measures should add up to 180 degrees, as they form a straight line. Therefore, the measure of angle 8 is 180 degrees minus the measure of angle 3, which is 180 - 30 = 150 degrees.

So, if angle 1 in rectangle WXYZ is 30 degrees, then angle 8 measures 150 degrees.

The function checks if the result for the current inputs has already been computed and stored in the `memo` cache. If so, it returns the cached result, otherwise it calculates the result using the recursive definition of the Bessel polynomials and stores the result in the `memo` cache for future use.

Memoization is a technique where we store the results of expensive function calls and return the cached result when the same inputs occur again. Here's a recursive function that uses memoization to calculate the n-th Bessel polynomial at x:

```
memo = {}  # Memoization cache

def B(n, x):
   if n == 0:
       return 1
   elif n == 1:
       return x + 1
   elif (n, x) in memo:
       return memo[(n, x)]
   else:
       result = (2 * n - 1) * x * B(n - 1, x) + B(n - 2, x)
       memo[(n, x)] = result
       return result
```

The function checks if the result for the current inputs has already been computed and stored in the `memo` cache. If so, it returns the cached result, otherwise it calculates the result using the recursive definition of the Bessel polynomials and stores the result in the `memo` cache for future use. This approach avoids redundant calculations and can significantly speed up the computation of Bessel polynomials for large values of n.

Given,

Sodium ion

Here,

Using nernst equation,

E = RT/nF \(ln\frac{Na_{ex} }{Na^+_{in} }\)

E = 58mV

When \({Na_{ex}\) increased by a factor of 10,

E' = RT/nF ln(10 Na)/Na

option b is correct - covariance

The correlation coefficient (r ) is a numerical measure that measures the strength and direction of a linear relationship between two quantitative variables.

Covariance

A numerical measure of linear association between two variables.

Covariance is a measure of how changes in one variable are associated with changes in a second variable. Specifically, covariance measures the degree to which two variables are linearly associated. However, it is also often used informally as a general measure of how monotonically related two variables are.  It is similar to variance, but where variance tells you how a single variable varies, covariance tells you how two variables vary together.

The distance covered by Rayann in millimeters in all is 92,955,807 millimeters

To determine how many millimeters she traveled in all, we will simply add the distance she traveled at first (from camp to the jungle) to the distance she traveled at the second time (looking for Zebras in the jungle).

From the question, the distance Rayann walked from camp to get to the jungle = 26,027,626 millimeters

and the distance she walked looking for Zebras = 66,928,181 millimeters

∴ The distance she traveled in all = 26,027,626 millimeters + 66,928,181 millimeters

The distance she traveled in all = 92,955,807 millimeters

Step-by-step explanation:

I got this answer simply by plugging each number into my calculator with the following equation:

\(\sqrt{x^{2} +y^{2} }\)

When you the lower numbers into the equation, if the lengths really do give you a triangle, then you should get the largest number as your output. This can help you with any of the other questions that you may have to answer.

Only the measurements of 16 cm, 30 cm, and 34 cm could represent the side lengths of a right triangle.

In a right-angled triangle, its sides, such as hypotenuse, and perpendicular, and the base is Pythagorean triplets.

Here,

The side lengths of a right triangle must satisfy the Pythagorean theorem, which states that the sum of the squares of the two shorter sides (the legs) is equal to the square of the longest side (the hypotenuse). Therefore, we need to check which sets of measurements satisfy this condition.

Only the measurements of 16 cm, 30 cm, and 34 cm could represent the side lengths of a right triangle.

For the first set of measurements, we have:

a = 16 cm, b = 30 cm, c = 34 cm

a² + b² = 256 + 900 = 1156

c² = 1156

Since a² + b² = c², these measurements do represent the side lengths of a right triangle.
