Answer:

Option B

Step-by-step explanation:

sqrt(22x^6) / sqrt(11x^4) = sqrt(2x^2)
sqrt(2x^2) can be rewritten as x sqrt(2)

For A.

First, we need to calculate the distance between Helicopter 1 and the fire

Fire (-3,-5)

Helicopter 1 (1,4)

the formula of the distance between 2 points is

where

(-3,-5)=(x1,y1)

(1,4)=(x2,y2)

we substitute the values

We didn't send helicopter 1 because it is a located 9.85 miles from the fire and it is only useful if it is within 9 miles so we don't send it

For B.

we need to calculate the distance between the fire and Helicopters 2 and 3

Helicopter 2 (-2,3)

Helicopter 3(4,-2)

Distance between helicopter 2 and the fire

(-2,3)=(x1,y1)

(-3,-5)=(x2,y2)

Distance between helicopter 3 and the fire

(4,-2)=(x1,y1)

(-3,-5)=(x2,y2)

as we can see the distance between the fire and helicopter 2 is bigger than 8, the distance between helicopter 3 and the fire is less than 8 therefore we will send the Helicopter 3

we know that

If (x-a) is a factor of P(x)

then

For x=a

Answer: the answer is C

Step-by-step explanation:

On the map, a trail is 5 1/4 inches long, its actual length is 3 and 1/2 miles. Option C is correct.

As given that, A trail map has a scale of 3 inches to 2 miles. To determine the actual length of the measure 5 1 / 4 inches in miles.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
3 inches = 2 miles
1 inches = 2 / 3 miles
multiply both side by 5 1/4 = 21 / 4
21 / 4 inches = 21 / 4 * 2 / 3 miles
21 / 4 inches = 3 1/2 miles

Thus, on the map, a trail is 5 1/4 inches long, and its actual length is 3 and 1/2 miles. Option C is correct.

Considering the given information, we fail to reject the null hypothesis that the proportion of men who own cats is less than or equal to 23% at the 0.10 significance level.

The null and alternative hypotheses are as follows:

H o: p ≤ 0.23 (proportion of men who own cats is less than or equal to 23%)

H a: p > 0.23 (proportion of men who own cats is larger than 23%)

The test is right-tailed because the alternative hypothesis states that the proportion is larger than 23%.

Based on a sample of 40 people, with 15% of them owning cats, we can calculate the p-value.

To find the p-value, we need to use the binomial distribution and calculate the probability of observing a result as extreme or more extreme than the one obtained under the null hypothesis.

Let's calculate the p-value:

p = 0.15 (proportion of men in the sample who own cats)

n = 40 (sample size)

p-value = P(X ≥ 0.15 x 40) = P(X ≥ 6)

Using a binomial calculator or software, we can find that P(X ≥ 6) is approximately 0.162.

Since the p-value (0.162) is greater than the significance level of 0.10, we fail to reject the null hypothesis.

Therefore, based on the given information, we fail to reject the null hypothesis that the proportion of men who own cats is less than or equal to 23% at the 0.10 significance level.

Answer:

Probability is the chances of something happening.

Step-by-step explanation:

The expected value of each warranty sold is $59.6 for the time duration of two year.

Warranty can be called as offer or surety given by company to his customer that if something happens with the product within the given time period either company refund the money or exchange the product or repair the product on the basis of terms and condition mention by the company when they gave the product to the customer.

Warranty sold for $60.

The product fails during the warranty period with 0.001 = 0.1% probability. In this case, the company has to replace the product with a cost of $150, having a net loss of 400 - 60 = $340

probability that it does not has to reimburse the client, 1-0.1% = 99.9% = 0.999 , so it gains $60.

The company's expected value of each warranty sold

0.999*60 - 0.001*340 = 59.94 - 0.34 = 59.6

The expected value of each warranty sold is $59.6

Step-by-step explanation:

The area of the square with a side length of 3.1 meters is 9.61 square meters.

To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.

Area of a square = side length × side length

Substituting the given side length into the formula:

Area = 3.1 m × 3.1 m

To perform the calculation:

Area = 9.61 m²

It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.

Remember, to find the area of any square, you simply need to multiply the length of one side by itself.

Answer:

a) \(\frac{dz}{dt} = e^{t}\cdot (2\cdot t+2\cdot t^{2}-1)\)

b) \(\frac{dz}{dt} = [4\cdot \ln t\cdot \sin^{3} 4t - \sin 4t \cdot \sin (2\ln t)]\cdot \left(\frac{2}{t} \right)+[12\cdot (\ln t)^{2}\cdot \sin^{2} 4t + \cos (2\cdot \ln t)]\cdot (4\cdot \cos 4t)\)

Step-by-step explanation:

In this exercise we use implicit differentiation to define \(\frac{dz}{dt}\):

a) \(z = x\cdot e^{x\cdot y}\), \(x = t^{2}\), \(y = t^{-1}\)

\(\frac{dz}{dt} = \frac{dx}{dt}\cdot e^{x\cdot y} +x\cdot e^{x\cdot y}\cdot \left[\frac{dx}{dt}\cdot y+x\cdot \frac{dy}{dt} \right]\)

\(\frac{dz}{dt} = e^{x\cdot y}\cdot \left\{\frac{dx}{dt}+x\cdot \left[\frac{dx}{dt}\cdot y+x\cdot \frac{dy}{dt} \right] \right\}\)

\(\frac{dz}{dt} = e^{x\cdot y}\cdot \left[(1+x\cdot y)\cdot \frac{dx}{dt}+x\cdot \frac{dy}{dt} \right]\)(1)

\(\frac{dx}{dt} = 2\cdot t\), \(\frac{dy}{dt} = -t^{-2}\)

\(\frac{dz}{dt} = e^{t}\cdot \left[(1+t)\cdot 2\cdot t +t^{2}\cdot (-t^{-2})\right]\)

\(\frac{dz}{dt} = e^{t}\cdot (2\cdot t+2\cdot t^{2}-1)\)

b) \(z = x^{2}\cdot y^{3}+y\cdot \cos x\), \(x = \ln t^{2}\), \(y = \sin (4\cdot t)\)

\(\frac{dz}{dt} = 2\cdot x\cdot y^{3}\cdot \frac{dx}{dt} +x^{2}\cdot (3\cdot y^{2})\cdot \frac{dy}{dt}+(\cos x)\cdot \frac{dy}{dt} +y\cdot (-\sin x)\cdot \frac{dx}{dt}\)

\(\frac{dz}{dt} = (2\cdot x\cdot y^{3}-y\cdot \sin x)\cdot \frac{dx}{dt} + (3\cdot x^{2}\cdot y^{2}+\cos x)\cdot \frac{dy}{dt}\)

\(x = \ln t^{2}\)

\(x = 2\cdot \ln t\)

\(\frac{dx}{dt} = \frac{2}{t}\), \(\frac{dy}{dt} = 4\cdot \cos 4t\)

\(\frac{dz}{dt} = [4\cdot \ln t\cdot \sin^{3} 4t - \sin 4t \cdot \sin (2\ln t)]\cdot \left(\frac{2}{t} \right)+[12\cdot (\ln t)^{2}\cdot \sin^{2} 4t + \cos (2\cdot \ln t)]\cdot (4\cdot \cos 4t)\)

Answer: 2.5

Step-by-step explanation:

\(3x+x+1=11\\\\4x+1=11\\\\4x=10\\\\x=2.5\)

Answer:

Step-by-step explanation:

a_1 = 15

a_2 = a_1  - 3

a_2 = 15 - 3

a_2 = 12

a_3 = a_2  - 3

a_3 = 12 - 3

a_3 = 9

a_4 = a_3 - 3

a_4 = 9 - 3

a_4 = 6

a_5 = 3

a_6 = 0                  I'm leaving these last two to expand

a_n = a1 - (n - 1)*d

a_n = 15 - (n - 1)*3

a_n = 15 - 3n + 3

a_n = 18 - 3n

Example

a_6 = 18 - 3*6

a_6 = 0

Problem B

t(1) = 108

t(1 + 1) = 1/3 * 108

t(2) = 36

t(3) = 1/3 * t2

t(3) = 1/3 * 36

t(3) = 12

t(4) =1/3 (t(3))

t(4) = 1/3 * 12

t(4) = 4

t(5) = t4 / 3

t(5) = 4 / 3

t(5) = 1.3333333

So the explicit definition is

t(n) = 108 (1/3)^(n - 1)            You could simplify this a little bit by realizing that 108 is made of three 3s.

t(n) = 4 * 3^3 * (1/3)^(n - 1)

t(n) = 4 * (1/3) ^ (n - 4)

Example

t(5) = 108 (1/3)^4

t(5) = 108(1/81)

t(5) = 1.3333333

And using the simplified formula, you get.

t(5) = 4 * (1/3)^1

t(5) = 1.333333 which is the same thing as the original result.

Answer:

Step-by-step explanation:

(a)

Using the recursive rule and a₁ = 15 , then

a₂ = a₁ - 3 = 15 - 3 = 12

a₃ = a₂ - 3 = 12 - 3 = 9

a₄ = a₃ - 3 = 9 - 3 = 6

The sequence is 15, 12, 9, 6, ....

This is an arithmetic sequence with n th term ( explicit rule )

\(a_{n}\) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 15 and d = - 3 , then

\(a_{n}\) = 15 - 3(n - 1) = 15 - 3n + 3 = 18 - 3n

----------------------------------------------------------------------

(b)

Using the recursive rule and t₁ = 108 , then

t₂ = \(\frac{1}{3}\) t₁ = \(\frac{1}{3}\) × 108 = 36

t₃ = \(\frac{1}{3}\) t₂ = \(\frac{1}{3}\) × 36 = 12

t₄ = \(\frac{1}{3}\) t₃ = \(\frac{1}{3}\) × 12 = 4

The sequence is 108, 36, 12, 4, ......

This is a geometric sequence with n th term

\(t_{n}\) = t₁\((r)^{n-1}\)

where t₁ is the first term and r the common ratio

Here t₁ = 108 and r = \(\frac{1}{3}\) , then

\(t_{n}\) = 108 \((\frac{1}{3}) ^{n-1}\)
