Answer:

y + 8 = - 3(x - 5)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (5 - 8) , thus

y - (- 8) = - 3(x - 5) , that is

y + 8 = - 3(x - 5)

Answer:

\(b=\frac{4c-a^{2} }{3}\)

Step-by-step explanation:

First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division

Then, you have \(4c=a^{2} +3b\)

Subtract both sides by a squared

DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition

From that you get \(4c-a^{2} =3b\)

Finally, divide both sides by 3.

You get  \(b=\frac{4c-a^{2} }{3}\)

Okay, let's evaluate the statements:

A. This is correct. Both logarithmic and exponential functions represent non-linear change.

B. This is incorrect. The logarithmic function can have negative x-values and the exponential function can have negative y-values.

C. This is correct. The base of the logarithm (which is -1 here) and the base of the exponential (which is e here, approximately 2.718) are positive.

D. This is incorrect. The logarithmic function can produce negative or positive output depending on the input x. The exponential function can also produce negative or positive output depending on the input.

So the correct statements are:

A. Both the logarithmic function and the exponential function represent change that is not linear.

C. The base of the logarithmic function and the base of the exponential function are both positive.

In summary, I would choose options A and C.

The probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

The true proportion (p) is given to be 0.03.

Therefore, Mean (μ) = p = 0.03.

The standard error of sampling distribution can be calculated using the formula σ = √[{p(1 - p)}/n], where n, is the sample size, that is, n = 476.

Therefore, σ = √[{0.03(1 - 0. 03)}/476] = 0.00782.

Since, np = 14.28 and n(1 - p) = 461.72 are both greater than 5, we assume the sample is normally distributed.

Since, we are asked to find the probability that the sample proportion is less than 0.04, we using our calculator, enter as following:

Normalcdf(-100000000,0.04,0.03,0.00782), which gives us the value 0.8995 or 89.95%.

Thus, the probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

If the test gives positive results for 95% of those having disease and correctly gives negative results for 90% of those who don't have disease and the incidence of the disease is 1% then the chance of having disease is 0.0105.

Given that a test for a disease correctly gives positive results for 95% of those having the disease and correctly gives negative results for 90% of those who don't have the disease.

We have to calculate the chance of having disease.

Probability that test is correct in determining the disease when person is suffering from it is 0.95.

Probability that test is not correct in determining the disease when person is suffering from it is 1-0.95=0.05.

Probability that test is correct in determining that the person is not suffering from disease  when person is not suffering from it is 0.90.

Probability that test is not correct in determining that the person is not suffering from disease  when person is not suffering from it is 1-0.9=0.10.

The chance of having disease is equal to incidence of disease multiplied by probabilities that the test has corectly determined disease when personis suffering from it and when test is not able to determine the disease when person is suffering from it.

Chance=0.01*0.95+0.01*0.10

=0.0095+0.001

=0.0105.

Hence the chance of having disease is 0.0105.

Since the two triangles are similar, this means that their corresponding sides are proportional. In other words:

\(\frac{PQ}{XY}=\frac{QR}{YZ}=\frac{RP}{ZX}\)

Part A:

We already know PQ, RP, XY, and YZ.

To find XZ, we can use the first and third proportions:

\(\frac{PQ}{XY} =\frac{RP}{ZX} \\=\frac{7.2}{18}=\frac{6.5}{ZX}\)

Cross multiply:

\(117=7.2(ZX)\\ZX \text{ or } XZ = 16.25\)

Part B:

The same thing as Part A, but with the first and second proportions:

\(\frac{PQ}{XY}=\frac{QR}{YZ}\\\frac{7.2}{18}=\frac{QR}{7}\\50.4=18(QR)\\QR=2.8\)

Answer:

140=7×2×2×5

Step-by-step explanation:

Answer:

If the original price of the car was $32600 and the dealership increased the price by 13%, we can start by calculating the amount of the increase:

Increase = 13% of 32600

Increase = 0.13 x 32600

Increase = 4238

So the increase in price is $4238. To find the new price of the car, we need to add this increase to the original price:

New price = Original price + Increase

New price = 32600 + 4238

New price = 36838

Therefore, the new price of the car is $36,838.

The series ∑ (k = 1 to infinity) 5^k / k! is convergent.

The Ratio Test is a method used to determine the convergence or divergence of a series by comparing the ratio of consecutive terms to a limit. For the given series, let's apply the Ratio Test:

Taking the ratio of consecutive terms:

|5^(k+1) / (k+1)!| / |5^k / k!|

Simplifying the expression:

|(5^(k+1) / (k+1)!) * (k! / 5^k)|

|5 / (k + 1)|

Now, we take the limit of this ratio as k approaches infinity:

lim(k->infinity) |5 / (k + 1)| = 0

Since the limit is less than 1, we can conclude that the series converges by the Ratio Test. In other words, the series ∑ (k = 1 to infinity) 5^k / k! is convergent.

The Ratio Test works by comparing the growth rate of consecutive terms in a series. If the ratio of consecutive terms approaches a value less than 1 as k goes to infinity, then the series converges. In this case, as the term k increases, the ratio 5 / (k + 1) approaches 0, indicating that the series converges.

Answer:

Hamish's earning = $20

Harry's earning = $26

Step-by-step explanation:

Given the following :

Let Harry's earning per hour = x

Let Hamish earning per hour = y

Harry earns a dollar more than more than 5/4 the amount hamish earns per hour;

Therefore,

x = 5/4y + 1

x - 5/4y = 1 - - - - (1)

the amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour

x = 7/5y - 2 - - - - (2)

Substituting (2) into (1)

7/5y - 2 - 5/4y = 1

7/5y - 5/4y = 1 + 2

7/5y - 5/4y = 3

Taking the L. C. M

(28y - 25y) / 20 = 3

28y - 25y = 60

3y = 60

y = 20

Substitute y = 20 into (1)

x - 5/4(20) = 1

x - 100/4 = 1

x - 25 = 1

x = 1 + 25

x = 26

y = Hamish's earning = $20

x = Harry's earning = $26

The flux = 0

According to the divergence theorem, the volume integral of the divergence of a vector point function "F" taken over the volume "V" encompassed by the surface "S" is equal to the surface integral of the normal component of F taken over the closed surface "S." As a result, the divergence theorem is symbolically represented as:∬ v ∫ ▽ F → .

The sphere is presumably closed, so we can use the divergence theorem.

▽ F  =d(xy)/dx + d(yz)/dy + d(zx)/dz

▽ F =x + y + z

Now convert to spherical coordinates:

x=ρsinφcosθ,

y=ρsinφsinθ,

z=ρcosφ

The flux is then given by the volume integral for the radius 6

\(\int\limits\int\limitsx_{x^{2} +y^{2}+z^{2} = 36 }\)   f.ds = \(\int\limits\int\limits\int\limitsx_{x^{2} +y^{2}+z^{2} < =36 }\) (x+y+z) dv

Thus the flux = 0

Step-by-step explanation:

The value of the function \(f(x)=3x^{2} -2x\) for x=4 is 40.

The given function is \(f(x)=3x^{2} -2x\).

We need to evaluate the given function for x=4.

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

To find the value of the given function replace x with 4 and simplify.

That is, \(f(4)=3(4)^{2} -2 \times 4=48-8=40\).

Hence, the value of the function \(f(x)=3x^{2} -2x\) for x=4 is 40.

The forces are equal in magnitude, but opposite in direction.

The wall doesn't move, and neither does your head when pushed against the wall. There's a balance of forces. We consider things to be in equilibrium.

If there was an imbalance of some sort, then there would be movement. For instance, if the wall somehow managed to enact a larger force compared to your head pushing, then you'd be pushed backward.

Another example: if you managed to enact a larger force, then the wall would move in the direction of your push.

Since none of those movements happen, we can see both forces are the same in magnitude but opposite in direction.

To establish whether findings from a sample may be extrapolated to the entire population, we use inferential statistics.

A population is the total group about which you want to reach conclusions. A sample is the specific group from which you will collect data. Always, the sample size is less than the whole population. The term "population" in research rarely refers to people. Using an office as an example, all of the employees would represent the Population, and all of the managers would represent the Sample. To create a comparison, picture your population as an ocean, and your sample as an aquarium.

Inferential statistics is a branch of statistics that uses data to draw inferences and generalizations about a certain situation or fact.
