An equation for a linear function is, [tex]h(x)[/tex] = 56[tex]x[/tex] - 63 where h(7)=329 and h(11)=553.

Given that,

h(7)=329 and h(11)=553

Linear function, y = [tex]mx + c[/tex]

Let, h = y and [tex]x =x[/tex]

A function whose graph is a straight line and which is represented by an equation of the form y = mx + c where a and b are constants, m does not equal zero, and x is any real number.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

So,

[tex]h(x)[/tex] = [tex]mx + c[/tex]

When,

[tex]x[/tex] = 7 , [tex]h(x)[/tex] = 329

( [tex]x_{1}[/tex] , [tex]h(x_{1} )[/tex] ) = ( 7 , 329 )      (Equation-1)

When,

[tex]x[/tex] = 11 , [tex]h(x)[/tex] = 553

( [tex]x_{2}[/tex] , [tex]h(x_{2} )[/tex] ) = ( 11 , 553 )         (Equation-2)

Linear function,

[tex]\frac{h(x)-h(x_{1} )}{x-x_{1} }[/tex] = [tex]\frac{h(x_{2} )-h(x_{1} )}{x_{2} -x_{1} }[/tex]

We can substitute equation -1 and 2

[tex]\frac{h(x)-329}{x-7}[/tex] = [tex]\frac{553-329}{11-7}[/tex]

[tex]\frac{h(x)-329}{x-7}[/tex] = 224/4

[tex]\frac{h(x)-329}{x-7}[/tex] = 56

[tex]h(x)[/tex] - 329 = 56 ( [tex]x-7[/tex] )

[tex]h(x)[/tex] - 329 = 56[tex]x[/tex] - 392

[tex]h(x)[/tex] = 56[tex]x[/tex] - 392 + 329

[tex]h(x)[/tex] = 56[tex]x[/tex] - 63

Therefore,

An equation for a linear function is, [tex]h(x)[/tex] = 56[tex]x[/tex] - 63 where h(7)=329 and h(11)=553.

The total differential to estimate the maximum error in the calculated volume of the cylinder is 200.96.

The base radius of a right circular cylinder are measured as 8 cm.

The height of a right circular cylinder are measured as 16 cm.

The possible error in measurement of as much as 0.2 cm each.

We have to calculate the maximum error in the calculated volume of the cylinder.

The formula of volume of cylinder is:

V = πr^2h

The value of dr = 0.2 and dh = 0.2. So;

dV(max) = ∂V/∂r dr + ∂V/∂dh dh

dV(max) = ∂(πr^2h)/∂r dr + ∂(πr^2h)/∂dh dh

On differentiating

dV(max) = 2πrh dr + πr^2 dh

r = 8 cm, π = 3.14 and h = 16 cm.

Now putting the value

dV(max) = 2×3.14×8×16×0.2 + 3.14×(8)^2×0.2

dV(max) = 160.768 + 40.192

dV(max) = 200.96

Hair color Categorical data is a type of data that can be stored into groups or categories with the aid of names.

Statistical information made up of categorical variables—data that have been divided into categories—is known as categorical data. A set of grouped data is one of example. More specifically, countable qualitative data or quantitative data clustered within predetermined intervals could be used to create category data. The information is condensed into a probability table. However, the word "categorical data," which is used to describe data sets, is used when discussing data analysis. It should be noted that although the data set includes some categorical variables, it may also include non-categorical variables.

Categorical data is a collection of information that is divided into groups. I.e, if an organization or agency is trying to get a biodata of its employees, the resulting data is referred to as categorical. This data is called categorical because it may be grouped according to the variables present in the biodata such as sex, state of residence, etc.

Answer:

x = 3

Step-by-step explanation:

Let's check

3^4 + 7(3)^2 - 144 = 0

81 + 63 - 144 = 0

144 - 144 = 0

0 = 0

So, x = 3 is the correct answer.

Z would ultimately have a value of 2, since 5 minus 7 equals 2.

x = 5; y = 7; z = x - y z = 5; y z = 7; z = 2;Consequently, z's final value is 2.

Given that x is 5 and y is 7, the final value of z would be 2. These two numbers are divided by two, giving the answer 2. Subtraction is the action of comparing two integers to determine their differences. In this instance, since x and y differ by 2, the ultimate value of z is also 2. The solution is 2, which can alternatively be written as 5 - 7 = 2. In this case, the ultimate value of z is 2, since the difference between x and y is 2, which can be found using the useful mathematical technique of subtraction.

Unit conversion is a process with multiple steps involving multiplication or division by a numerical factor, particularly a conversion factor. The procedure may also demand the selection of the correct number of substantial digits and rounding. Different units of conversion are used to calculate different parameters.

We convert the units of any quantity to understand better. For example, the length of a table is measured in inches; on the other hand, the length of a garden is measured in yards to make it simple to comprehend. We cannot calculate the length of a finger in miles.

79.1 mL is equal to 0.0791 litres. To convert millilitres to litres, we divide the number of millilitres by 1000:

79.1 mL / 1000 = 0.0791 liters

Oliver is farther from the station.

Let's call the initial distance from the station for Oliver and Roel as d1 and d2, respectively. The Law of Cosines states:

d1^2 = 3^2 + 4^2 - 2 * 3 * 4 * cos(30°)

d2^2 = 3^2 + 4^2 - 2 * 3 * 4 * cos(40°)

By solving the above equations, we can determine the distances d1 and d2. The hiker who is farther from the station will have the larger value of d1 or d2.

In this case, it can be seen that d1 > d2, meaning Oliver is farther from the station than Roel.

This is because the angle of 30° is larger than the angle of 40°, so the cosine of 30° is smaller than the cosine of 40°.

Therefore, Oliver is farther from the station.

Answer:

f(x) = -4[tex]x[/tex] - 2 or y = -4[tex]x[/tex] - 2

Step-by-step explanation:

In this question, you should use the graph to write the function/equation in slope intercept form.

y = mx + b where m is the slope and b is the y intercept

To calculate the slope, you can use rise/run between any two points. I will use the points (-2, 6) and (0, -2). In these points, the "rise" would be -8 as that is the number of units they are away from each other vertically. It is negative because the line obviously has a negative slow as it is travelling from up to down. The run in this case would be 2 as that is the distance the two points are away from each other horizontally.

Then, substitute.

[tex]\frac{-8}{2}[/tex] = -4, so m = -4

Now we will find the b value.

B is the y-intercept, or what the y value of the coordinate of the point that the line touches the y-axis. The coordinate is (0, -2). Therefore, the b value is 2.
