The formula of g(x) is g(x) = -0.8x - 1.6

The equation is given as:

-4x - 6 = 5y + 2

Subtract 2 from both sides

5y = -4x - 8

Divide through by 5

y = -0.8x - 1.6

Express as a function

g(x) = -0.8x - 1.6

Hence, the formula of g(x) is g(x) = -0.8x - 1.6

To find the total differential of the function w = e^y * cos(x) * z^2, we can take the partial derivatives with respect to each variable (x, y, and z) and multiply them by the corresponding differentials (dx, dy, and dz).

The total differential can be expressed as:

dw = (∂w/∂x) dx + (∂w/∂y) dy + (∂w/∂z) dz

Let's calculate the partial derivatives:

∂w/∂x =   \(-e^{y} * sin(x) * z^{2}\)

∂w/∂y =  \(e^{y} * cos(x) * z^{2}\)

∂w/∂z =  \(2e^{y} *cos (x)* z\)

Now, let's substitute these partial derivatives into the total differential expression:

\(dw = (-e^{y} * sin(x) * z^{2} ) dx + (e^{y}* cos(x) * z^{2} ) dy + 2e^{y} *cos (x)*z) dz\)

Therefore, the total differential of the function w = e^y * cos(x) * z^2 is given by:

\(dw = (-e^{y} * sin(x) * z^{2} ) dx + (e^{y} * cos(x) * z^{2} ) dy + ( 2e^{y} * cos(x) * z) dz\)

According to the standard deviation, the company should offer a warranty period that covers at least 65,895 miles to ensure that 96% of the tires sold will outlast the warranty.

To do this, we use a z-score table, which gives the probability of getting a z-score less than or equal to a given value. The z-score is a measure of how many standard deviations a data point is from the mean.

To find the z-score for the top 4% of the tires, we first subtract 96% from 100% to get 4%. Then we divide this by 2 to get 2%, as we are interested in the area under the normal distribution curve in the right tail. Using the z-score table, we find that the z-score corresponding to a 2% area under the curve is approximately 2.05.

Next, we use the formula for converting a z-score to a data value:

z = (x - μ) / σ

where z is the z-score, x is the data value, μ is the mean, and σ is the standard deviation. Solving for x, we get:

x = z x σ + μ

Plugging in the values, we get:

x = 2.05 x 2700 + 60000

x ≈ 65,895

The difference between (7x - 9) and (8x - 5), we need to subtract the second expression from the first.

(7x - 9) - (8x - 5)

To simplify this expression, we distribute the negative sign to the terms inside the parentheses:

7x - 9 - 8x + 5

Next, we can combine like terms by adding or subtracting coefficients of similar variables:

The maximum depth under water at which the shell of a chambered nautilus can withstand the pressure is 2589 feet (rounded to the nearest foot).

To determine the maximum depth at which the shell of a chambered nautilus can withstand the pressure, we need to calculate the total pressure the shell can endure and then convert it to depth. The total pressure consists of atmospheric pressure and hydrostatic pressure per foot of depth underwater.

The atmospheric pressure is 14.7 psi, and the hydrostatic pressure per foot of depth is 0.45 psi. We can set up the equation:

Total Pressure = Atmospheric Pressure + Hydrostatic Pressure * Depth

We know that the maximum pressure the shell can withstand is 1180 psi. By substituting the given values into the equation, we can solve for the depth. Rearranging the equation, we have:

1180 psi = 14.7 psi + 0.45 psi/ft x  Depth

Simplifying the equation, we get:

0.45 psi/ft x Depth = 1180 psi - 14.7 psi

By subtracting the atmospheric pressure from the total pressure, we find:

0.45 psi/ft x Depth = 1165.3 psi

Finally, by dividing both sides of the equation by 0.45 psi/ft, we can determine the depth to the nearest foot at which the shell can withstand the pressure. The calculated depth is approximately 2589 feet. Therefore, the maximum depth under water at which the shell of a chambered nautilus can withstand the pressure is 2589 feet (rounded to the nearest foot).

The volume of the pyramid is 3733.33 m³.

Having a square base and four lateral sides, a square pyramid is a type of pyramid in geometry. Having three or more triangular faces that intersect above its base, a pyramid is a particular kind of polyhedron (the apex).

The building is in the shape of a square pyramid.

The base of the building is 20 meters long.

The height of the building is 28  meters.

The volume of the right square pyramid is given as:

V = ( 1/3)a²h

Where a is the base and h is the height.

Now we have,

a = 20 m and h = 28 m

So,

V = ( 1/3 ) × 20 × 20 × 28

The given function f, with the provided set of ordered pairs, has a domain of {10, 17, 45, 51} and a range of {-6, 1, 5}.

The domain of a function refers to the set of all possible input values or x-values for which the function is defined. In this case, the given set of ordered pairs determines the domain. Looking at the x-values in the set {10, 17, 45, 51}, these are the unique inputs for which the function f is defined. Hence, the domain of f is {10, 17, 45, 51}.
On the other hand, the range of a function refers to the set of all possible output values or y-values that the function can take. By examining the y-values in the set {-6, 1, 5}, we can observe the distinct outputs generated by the function f. Thus, the range of f is {-6, 1, 5}.

Answer: the probability of being offered both jobs is 0.05, or 5%

Step-by-step explanation:

To solve this problem, we can use the formula:

P(A or B) = P(A) + P(B) - P(A and B)

where P(A or B) is the probability of getting at least one job offer, P(A) is the probability of getting an offer for job A, P(B) is the probability of getting an offer for job B, and P(A and B) is the probability of getting an offer for both jobs.

Substituting the given values, we get:

0.40 = 0.25 + 0.20 - P(A and B)

Solving for P(A and B), we get:

P(A and B) = 0.25 + 0.20 - 0.40 = 0.05

Therefore, the probability of being offered both jobs is 0.05, or 5% (rounded to two decimal places).

  San Francisco

Step by step explanation:

Given that 1 US gallon of petrol costs $3.34 in San Francisco, and 1 litre of petrol costs 107.6p in Manchester, with conversion rates being 3.785 litres per gallon and $1.46 per 1£, you want to know the city where the value is better.

We can compare the costs by converting the rate in Manchester to a dollar cost per gallon.

The cost of 1 litre in Manchester is £(107.6/100) = £1.076. The cost of 1 US gallon of petrol in Manchester is 3.785 × £1.076 = £4.07226. Converted to dollars, that is 4.07266 × $1.46 ≈ $5.95.

In San Francisco, the cost of 1 US gallon is $3.34.Therefore, the cost of 1 US gallon of petrol in San Francisco is a better value. The price of petrol is higher in Manchester than in San Francisco.

What is standard deviation?

A set of values' variance or dispersion is measured by the standard deviation. While a high standard deviation implies that the values are dispersed over a wider range, a low standard deviation shows that the values tend to be close to the mean of the collection.

Given: Mean = 80, s = 5.

Computing values to standard deviation from mean,

Lower limit = mean - 2s

                 = 80 - 2(5)

                 = 80 - 10

Lower limit = 70

Hence, if x has a normal distribution with mean 80 and standard deviation 5 then the 90th percentile of x is 70.
