The two possible non-zero values of k in terms of a and b for the given differential equation is √(-b/a) and -√(-b/a).

The characteristic equation of the differential equation is given by:

a*k^2 + b = 0

Solving for k, we get:

k = +/- sqrt(-b/a)

The general solution to the differential equation ay'' + by = 0 is given by

y = C1 * cos(sqrt(b/a) * t) + C2 * sin(sqrt(b/a) * t)

where C1 and C2 are constants determined by the initial conditions.

The area of r is 18.

1. First, we need to find the intersection of the curve and the line y = 6. We can do this by setting the two equations equal to each other and solving for x.

y = x−−√

y = 6

x = 6

2. Next, we need to calculate the area of the region. We can do this by using the formula for the area of a triangle.

A = 1/2 * base * height

A = 1/2 * 6 * (6 - √6)

A = 18

Therefore, the area of the region r is 18.

Step-by-step explanation:1500-1322=178

178:60=2.9... =>3h

They need to drive for approximately3 hours, to cover the remaining 178 miles and reach their goal of the 1,500-mile mark by the end of the day tomorrow.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,

To reach the 1,500-mile mark, Henrietta's family needs to travel an additional 1,500 - 1,322 = 178 miles.

Since they averaged a speed of 60 miles per hour so far, we can use the formula:

distance = speed × time

To find out how long they need to drive to cover the remaining 178 miles. Solving for time, we get,

time = distance/speed

time = 178 miles ÷ 60 miles per hour

time = 2.967 hours

This means they need to drive for approximately3 hours, to cover the remaining 178 miles and reach their goal of the 1,500-mile mark by the end of the day tomorrow.

Answer:

5th term is 9, 30, and -20.3 and the 23rd term is 45, 174, and -132.9

Step-by-step explanation:

The given pattern consists of three mathematical expressions: 2x + 1, 8x - 2, and -6.2x + 4.5. To find the 5th and 23rd term of the pattern, we need to substitute x with the corresponding value and evaluate the expressions for each of the terms.

For the 5th term:

x = 5-1 = 4

So, the 5th term would be:

2x + 1 = 2 * 4 + 1 = 9

8x - 2 = 8 * 4 - 2 = 30

-6.2x + 4.5 = -6.2 * 4 + 4.5 = -24.8 + 4.5 = -20.3

For the 23rd term:

x = 23-1 = 22

So, the 23rd term would be:

2x + 1 = 2 * 22 + 1 = 45

8x - 2 = 8 * 22 - 2 = 174

-6.2x + 4.5 = -6.2 * 22 + 4.5 = -136.4 + 4.5 = -132.9

Therefore, the 5th term is 9, 30, and -20.3 and the 23rd term is 45, 174, and -132.9 for the given pattern of mathematical expressions.

The big-O limit lemma states that if f(n) = O(g(n)) as n approaches infinity, then lim n→∞ f(n)/g(n) = C for some constant C.

We must demonstrate that for any constant C > 0, there exists an N such that for all n > N, |log(n)| C*n in order to demonstrate that log(n) = o(n). Here's how to go about it:

For any constant C > 0, choose N = e^C. Then, for all n > N, we have:

log(n) < C

So, |log(n)| < C

And, |log(n)| < C*n

This means that log(n) = o(n), as required.

To show that n^x log(n) = o(n^x) for any constant x, we use the big-O limit lemma. Since log(n) = o(n), we have:

lim n→∞ (n^x log(n))/(n^x) = lim n→∞ log(n)/n^(x-1) = C for some constant C.

Since the limit of the right side is a finite constant, we can conclude that n^x log(n) = o(n^x), as required.

To find the height of the hill, we can use the tangent function. Let h be the height of the hill and x be the distance from the person to the base of the hill. We know that:

tan 1.5° = 127 / x

and

tan 25° = h / x

We can use the first equation to find x:

x = 127 / tan 1.5°

And then substitute x into the second equation to find h:

h = x * tan 25° = (127 / tan 1.5°) * tan 25°

This gives us the height of the hill. You can use a calculator to find the value of h.

The point on the x-axis that lies on the line passing through point C and parallel to line AB is (4, 0).

A line that is parallel to line AB and passes through point C has the same slope as line AB. The slope of line AB can be found using the formula:

m = (y2 - y1) / (x2 - x1),

where (x1, y1) and (x2, y2) are the coordinates of the two points on the line.

In this case, (x1, y1) = (negative 4, 0) and (x2, y2) = (2, negative 3).

Substituting these values into the formula, we get:

m = (-3 - 0) / (2 - -4) =  -3 / 6 = -1/2

Since the slope of line AB is -1/2,

the slope of the line through point C and parallel to line AB is also -1/2.

A line with slope -1/2 and passing through (negative 2, 2) has the equation:

y - 2 = -1/2 (x - -2),

Rearranging this equation to solve for y, we get:

y = -1/2 x + 2

The x-axis has y-coordinate 0, so substituting 0 for y in the equation, we get:

0 = -1/2 x + 2

Solving for x, we get:

x = 4

hence the point is (4, 0)

The percent of real fruit juice in the first brand if the mixture contained 30% real fruit juice is 14.

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100.

Let the percent of the real fruit in the first brand = x

Given that number of gallons of  real fruit in the first brand = 9 gallons

Given that percent of the real fruit in the second brand = 48%

Given that number of gallons of  real fruit in the second brand = 8 gallons

Given that  percent of the real fruit in the mixture = 30%

then number of gallons of  real fruit in the mixture = (9+8) = 17 gallons

Then we get equation:

[x% of 9 gallons] + [48% of 8 gallons] = [30% of 17 gallons]

9x+48(8)=30(17)

9x+384=510
