The function u(t) = c1e^3t + c2e^-4t satisfies the given ordinary differential equation (ODE) u"(t) + u'(t) - 12u(t) = 0. By finding the values of c1, c2, ER, and ER that satisfy the initial conditions u(0) = 40 and u'(0) = 46, we can determine the specific solution. Finally, we can calculate the value of u(0.1) using the obtained values of c1 and c2.

To show that the function u(t) = c1e^3t + c2e^-4t satisfies the ODE u"(t) + u'(t) - 12u(t) = 0, we need to take the derivatives of u(t) and substitute them into the ODE equation. After performing the necessary calculations, it can be shown that the equation holds true.

To find the values of c1, c2, ER, and ER that satisfy the initial conditions u(0) = 40 and u'(0) = 46, we substitute t = 0 into the equation u(t) = c1e^3t + c2e^-4t and its derivative u'(t) = 3c1e^3t - 4c2e^-4t. By equating these expressions to the given initial values, we can solve for c1 and c2.

Once c1 and c2 are determined, we can calculate the value of u(0.1) by substituting t = 0.1 into the expression u(t) = c1e^3t + c2e^-4t. Evaluating this expression will give us the specific value of u(0.1), rounded to four decimal places.

Answer:

R(x) = 2.25x + 4.49

Step-by-step explanation:

Equation form: R(x) = mx + b

m: represents the additional amount Joshua is charged for every day until he returns the movie, which in this case is $2.25. So, the value of m is 2.25.

b: represents the initial cost of renting the movie. Joshua rented the movie for $4.49, so b is 4.49.

Since we know the value of m and b, we can write the equation:

R(x) = 2.25x + 4.49

Therefore, the standard error of the mean, σ= 2.53 (approx).

Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.

Given: A simple random sample of 10 items resulted in a sample mean of 25.

The population standard deviation is = 8.

We have to find out the standard error of the mean, σ/Sample Size n,

so we will first calculate σ as;

σ = Population standard deviation = 8

Sample Size n = 10

Substituting values in the formula to find the standard error of the mean, we get;σ/√n = 8/√10 = 2.53 (Round off the value to two decimal places)

Answer: The length of AC to one decimal place in the trapezium is 18.1 cm

Step-by-step explanation: Using Pythagoras theorem, we can find the length AC

Pythagoras theorem

c² = a² + b²

Therefore, draw a line from the point B to the line AD and call it line BX.

BX ║ CD

Therefore,

16² - 7² = BX²

256  - 49 = BX²

BX² = 207

BX = √207

BX = 14.3874945699

BX = 14.4 cm

Therefore,

11² + 14.4² = AC²

121 + 207.36 = AC²

AC = √328.36

AC = 18.120706388

AC = 18.1 cm

Step-by-step explanation:

Part A

1, - 2x + 3y = - 13

3x - 3y = 12

We would apply the method of elimination. Since the coefficients of y in both equations are the same, we would eliminate y by adding both equations. It becomes

- 2x + 3x + 3y + - 3y = - 13 + 12

- 2x + 3x + 3y - 3y = - 1

x + 0 = - 1

x = - 1

We would substitute x = - 1 into the first equation. It becomes

- 2(-1) + 3y = - 13

2 + 3y = - 13

3y = - 13 - 2

3y = - 15

y = - 15/3

y = - 5

The solutions are (- 1, - 5)

2. - 9x - y = 29

9x + y = - 29

We would apply the method of elimination. Since the coefficients of y in both equations are the same, we would eliminate y by adding both equations. It becomes

- 9x + 9x - y + y = 29 + - 29

- 9x + 9x - y + y = 29 - 29

0 - 0 = 0

7.051 can be written as the fraction 7051/1000.

To express 7.051 as a fraction in the form of p/q, we need to identify the decimal places and convert them to the corresponding fractional parts.

Since 7.051 has three decimal places, we multiply it by 1000 to move the decimal point three places to the right, which gives us 7051.

Now, the numerator (p) of the fraction will be 7051, and the denominator (q) will be the corresponding power of 10, which is 1000.

Therefore, 7.051 can be expressed as 7051/1000.

To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD).

In this case, the GCD of 7051 and 1000 is 1, so the fraction is already in its simplest form.

The distance to the radio horizon for an antenna that is 40 ft above the top of a 4000 ft mountain peak is approximately 78.18 miles.

The radio horizon refers to the point beyond which radio signals from a given transmitter can no longer be received due to the curvature of the Earth's surface. It can be calculated using the formula d = 1.23√h, where d is the distance to the radio horizon in miles and h is the height of the antenna above ground level in feet.

So, the height of the antenna above ground level is as follows:

4000 + 40 = 4040 ft.

Substituting into the formula, we get

d = 1.23√4040 ≈ 78.18 miles.

Therefore, the distance to the radio horizon for an antenna that is 40 ft above the top of a 4000 ft mountain peak is approximately 78.18 miles.

The required equations that are equivalent to each other are,

(A)  2 + x = 5    (B) x + 1 = 4   (E) -5 + x = -2.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Given equations,

(A) 2 + x = 5

Simplifying the above expression,

x = 5 - 2

x = 3

Similarly, simplify all the equations,

(B) x = 3

(C) x = -3

(D) x = 11

(E) x = 3

Therefore, equations that give x = 3, after simplification is equivalent equations.

The correct option is B. The Wolverines' distribution is negatively skewed, but the Panthers' distribution is symmetric.

Data is symmetric if the median is in the mid of the box plot and the box is mid to the line connecting both whiskers.

The box plot showing scores for the Panthers basketball team has the median shown by a vertical line dividing the box into 2 equal halves.

Also, both whiskers on either side are relatively equal which shows that the data set for bulldogs is symmetric.

On the other side, the box plot for wolverine shows the median closer to the upper quartile.

That shows that the data set for team Wolverines' distribution is negatively skewed.

The given series is convergent and it's sum is e⁸.

To show that the series is convergent, we can express the partial sum s_n as a telescoping sum.

s_n = e⁸/1 - e⁸/2 + e⁸/2 - e⁸/3 + e⁸/3 - … - e⁸/(n+1) + e⁸/(n+1)

= e⁸ - e⁸/(n+1)

As n approaches infinity, e⁸/(n+1) approaches 0, so the limit of s_n is e⁸. Therefore, the given series is convergent with sum e⁸.

Answer:

C. 6.02sec

Step-by-step explanation:

Given

\(h(t) = -16t\² +96t + 2\)

Required

Time to hit the ground

When the turtle shell hits the ground, \(h(t) = 0\)

So:

\(0 = -16t\² +96t + 2.\)

Solving using quadratic formula:

\(t = \frac{-b\±\sqrt{b^2-fac}}{2a}\)

Where:

\(a = -16; b =96; c = 2\)

So:

\(t = \frac{-96\±\sqrt{96^2-4 * -16 * 2}}{2*-16}\)

\(t = \frac{-96\±\sqrt{9344}}{-32}\)

\(t = \frac{-96\±96.66}{-32}\)

Split:

\(t = \frac{-96+96.66}{-32}\) or \(t = \frac{-96-96.66}{-32}\)

\(t = \frac{0.66}{-32}\) or  \(t = \frac{-192.66}{-32}\)

\(t = -0.020625\) or  \(t = 6.020625\)

So time can't be negative, we have:

\(t = 6.020625\)
