Limit and say that the computation is justified by the limit laws x7limg(x)h(x)f(x) = -31.

A limit in mathematics is a value that a function approaches when the input gets closer to a certain value. Limits are used to find a function's derivative and integral as well as to characterize how a function behaves around particular places.

The following is the official definition of a limit: Let c be a real value and f(x) be a function. The symbol for the limit of f(x) as x gets closer to c is L.

lim x -> c f(x) = L

if for every ε > 0, there exists a δ > 0 such that for all x, 0 < |x - c| < δ implies |f(x) - L| < ε. In other words, as x gets arbitrarily close to c, the values of f(x) get arbitrarily close to L.

The limit can be computed as follows:

x→7limg(x)−h(x)f(x) = limx→7g(x)−h(x)limx→7f(x) = 5−3limx→7f(x) = 5−3(12) = 5−36 = -31

So, x→7limg(x)−h(x)f(x) = -31.

The limit of two functions that differ from one another is equal to the difference between their limits.

Answer:

37° and 63°

Step-by-step explanation:

the measure of a secant- secant angle and a tangent- tangent angle is half the measure of the intercepted arcs.

5

∠ 1 = [tex]\frac{1}{2}[/tex] (108 - 34)° = [tex]\frac{1}{2}[/tex] × 74° = 37°

6

the sum of the arcs in a circle is 360° , then

minor arc = 360° - 243° = 117°

∠ 1 = [tex]\frac{1}{2}[/tex] (243 - 117)° = [tex]\frac{1}{2}[/tex] × 126° = 63°

The process takes approximately 14 iterations to reach the desired accuracy.

The Bisection Method will take approximately 14 iterations to find the approximate root of the equation within an error tolerance of 0.001. The mathematics calculations involve finding the midpoint of a given interval [a, b] and then determining whether the midpoint is a root of the equation. If it is not a root, then the interval is divided into two halves, and the process is repeated on the subinterval where the sign of the function changes. This process is repeated until the midpoint is within the desired error tolerance.

To calculate the number of iterations required, we begin by noting that the initial interval used is [1, 0]. The midpoint of this interval is 0.5. This value is then plugged into the function to determine if it is a root. Since it is not, the interval is then divided into two halves and the process is repeated. This process is repeated until the midpoint is within the desired error tolerance of 0.001. In this case, it takes approximately 14 iterations to reach the desired accuracy.

The complete question is:

The total distance the tourist has to pay the taxi driver is the sum of the distance the tourist walked and the distance the taxi drove, or 8 miles + 100 miles = 108 miles.

The distance the tourist has to pay the taxi driver can be calculated using the formula for distance = rate x time.

First, let's find out how far the tourist walked. We know that he walked at a rate of 4 mph for 2 hours, so the distance he walked is 4 mph x 2 hours = 8 miles.

Next, let's find out how far the taxi drove. The taxi reached the destination 2 hours after the tourist started walking, so the time it took for the taxi to reach the destination is 2 hours. The taxi was traveling at a constant speed of 50 mph, so the distance it drove is 50 mph x 2 hours = 100 miles.

Answer:

C. 12,000(1.05)^n < 20,000

Step-by-step explanation:

A = P(1 + r)^t

P = $12,000

r = $5 dollar per year

t = n years

$12,000(1 + 5/100)^n

$12,000(1 + 0.05)^n

$12,000(1.05)^n

The question states, "The tuition is less than 20,000", therefore:

[$12,000(1.05)^n < 20,000]

The total distance traveled was 19 miles and the total time was 3/10 of an hour

The formula for calculating the average rate is distance divided by time, or D/T. In this problem, Jamel traveled 19 miles in a total time of 1/2 + 1/5 = 3/10 of an hour. Using the formula, the average rate can be calculated as 19/3/10 = 19/3 x 10/3 = 190/3 = 63.3 mph. Therefore, Jamel's average rate for the trip was 63.3 mph.

To explain further, when solving a problem involving average rate, it is important to remember the formula D/T. This means that the total distance traveled is divided by the total time. In this problem, the total distance traveled was 19 miles and the total time was 3/10 of an hour. To calculate the average rate, the total distance (19 miles) was divided by the total time (3/10 of an hour). This yielded a result of 190/3, which was further simplified to 63.3 mph.

The speed of the airplane in still air is 21.5 mph.

An airplane flying with the wind takes 2 hours with a 25-mph tailwind to reach its destination. the return trip takes 4 hours flying against the wind.

We must calculate the wind speed from the ground speed and airspeed as we cannot measure the wind speed directly from the aeroplane.

Flying at 35 mph requires four hours. Consequently, the distance is

25 * 2 = 50 miles.

For the same route, a return trip takes 5 hours.

Hence V-Vs= 50/4 = 12.5.

Therefore, V+Vs= 25 (1).

V-Vs = 12.5-----(2).

We obtain V=21.5 mph Vs=2.5 mph by solving for (1) and (2).

Thus, V = 21.5 mph is the airplane's windless speed.

From the given information:

f(x)=[tex]x^{3}[/tex]+6[tex]x^{2}[/tex]+17x+14​; slope of the tangent line=5

Then

f(x)=[tex]x^{3}[/tex]+6[tex]x^{2}[/tex]+17x+14

Now find the drivative then

f'(x)=3x^2+12x+17

Then slope of the tangent line=5

Now,

3[tex]x^{2}[/tex]+12x+17 = 5

3[tex]x^{2}[/tex]+12x+12 = 0

[tex]x^{2}[/tex]+4x+4 = 0

Now solve the equation then

[tex]1x^{2}[/tex]+2x+2x+4 = 0

x(x+2) +2(x+2) = 0

(x+2) (x+2) = 0

Here the values of the x become -2,-2.

Then

When x = 2

f(x)=[tex]2x^{3}[/tex]+[tex]6^{2}[/tex]+17(2)+14

f(x)=8+24+34+14

Rearrange this to solve for the radius:

r = √(A/π).

The original cone has a base area of 49 in², so:

The 8-Point Radix-2 Decimation-in-Frequency FFT is a fast Fourier transform algorithm used to decompose a signal into its individual frequency components.

The process begins by splitting the input sequence into even and odd samples using a butterfly operation. The even samples are then further split using a second butterfly operation, followed by a third butterfly operation on the odd samples. The outputs of the butterfly operations are then combined using a summation operation.

To draw the signal flow graph, we must first compute the intermediate values. The first step is to split the input sequence of 8 samples into two sequences of 4 samples each, with the even samples in the first sequence and the odd samples in the second. The second step is to further split the even samples into two sequences of 2 samples each. The third step is to apply a butterfly operation to the odd samples, resulting in two new sequences of 2 samples each. The fourth and final step is to combine the outputs from the butterfly operations using a summation operation.

By applying exponential decay concept, it can be concluded that the exponential equation to model the value of the snowmobile is A = 500 · 0.85ⁿ where n is the times (in years).

Exponential decay occurs when the amount of something decreases at a rate proportional to the amount left.

A = P (1 - r)ⁿ   where:

A = final amount

P = initial amount

r = decay factor

n = time

We have the following information:

P = $500

r = 15%

The exponential equation to model the value of the snowmobile can be written as follows:

A = P (1 - r)ⁿ

A = 500 (1 - 15%)ⁿ

A = 500 · 0.85ⁿ

The equation describes the growth of the number of people who have heard the rumor over time. The e^(-0.7t) term in the denominator represents the rate of decay or the slowing down of the spread of the rumor as t increases. As t increases without bound, the exponential term approaches 0, so the fraction approaches 550 / (1 + 49 * 0) = 550 / 1 = 550.
