Does anyone know how to do this. I really need help.

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.

Log x+y = logbx − logbyGiven log630 ≈ 1.898 and log62 ≈ 0.387, log615 ≈ 2.086.

Given log 630 ≈ 1.898 and log 62 ≈ 0.387,

We have log 630 = log (6 * 62 * 10) = log 6 + log 62 + log 10 = 1 + 0.387 + 1 = 2.387

And log 615 = log (6 * 62 * 5) = log 6 + log 62 + log 5 = 1 + 0.387 + 0.699 = 2.086

So, log 615 ≈ 2.086

In the example given, log 630 ≈ 1.898 and log 62 ≈ 0.387. These logarithmic values are used to simplify other logarithmic expressions and, the logarithm of 615 was found to be approximately 2.086.

The price per square foot of the house is $51.18.

The price per square foot of the house is determined by taking the total price of the house, $348,000, and dividing it by the total square footage of the house, 25' x 68' and we get $51.18.

For example- The total square footage is 1700, so when divided into the total cost, $348,000, the price per square foot of the house is $204.71. This means that for every square foot of the house, the buyer paid $204.71. The total cost of the house is a combination of the price per square foot in addition to any additional fees, such as taxes and closing costs.

When purchasing a home, it is important to know the price per square foot as this can help to determine the value of the home.

79.1 mL is equal to 0.0791 litres with correct significant figures.

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

So, 79.1 mL is equal to 0.0791 litres with correct significant figures.

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

You want to know which of the given sets of dimensions could be those of a right triangle.

A set of side lengths will form a right triangle if they satisfy the Pythagorean theorem:

  a² +b² = c²

  6² +8² = 36 +64 = 100 = 10² . . . . . {6, 8, 10} forms a right triangle

  12² +35² = 144 +1225 = 1369 = 37² . . . . . {12, 35, 37} forms a right triangle

  4 + 6 = 10 . . . . . {4, 6, 10} doesn't even form a triangle

  10² +24² = 100 +576 = 676 = 26² . . . . . {10, 24, 26} forms a right triangle

__

Additional comment

For three side lengths to form a triangle, the sum of the two short sides needs to be longer than the longest side. (This is the triangle inequality.)

Lengths 4, 6, 10 do not meet that requirement.

You may notice that the long sides of these triangles differ in length by 2 units. The short side is twice the square root of their average. This relation will hold for any right triangles having long sides that differ by 2.

  {6, 8, 10}  ⇒  6 = 2·√9

  {12, 35, 37}  ⇒  12 = 2·√36

  {10, 24, 26}  ⇒  10 = 2·√25

Along the same lines, if the longest sides differ by 1, the short side is the square root of their sum.

Factoring out negative 1 from the expression -4-(5+3) is -1(12).

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

A) 7+(-6)

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°.

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.

The best mathematical operation to use when considering the probability of data loss from single drive failure is XOR.

Data storage is a critical process, as any data loss could have disastrous consequences.

The XOR technique uses one extra device (C) to store the exclusive OR result of the data stored on devices A and B. This means that for each bit k, the value of Ck is the exclusive OR of ak and bk.

This means that if bit k fails on device A or B (not both), it can be reconstructed from bit k on device C. This is because the exclusive OR of two identical bits is 0 and the exclusive OR of two different bits is 1, which can be used to reconstruct the failed bit from the other one.

The same cannot be said of the AND or OR technique. If we use the AND technique, the value of Ck would be the logical AND of ak and bk.

In this case, the failed bit could not be reconstructed from the other bit, as the logical AND of two identical bits is the same bit and the logical AND of two different bits is 0.

The same problem applies for the OR technique, as the value of Ck would be the logical OR of ak and bk, and the failed bit could not be reconstructed from the other bit.

Thus, XOR is the best mathematical operation to use when considering the probability of data loss from single drive failure.

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,

When,

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