Write the equation in standard form. 0.5x = y - 4

Answers

Answer 1

Answer:

y = 0.5x + 4, or y = 1/2x + 4 (if you prefer fractions)

Step-by-step explanation:

y = mx + b (slope intercept form / standard form) ; m = 0.5 or 1/2, b = 4.

m = linear coefficient/slope(denoted by a in a 1 degree binomial)

b = constant coefficient / y-intercept (denoted by b in a 1 degree binomial)

to convert this equation into a standard form equation. You need to isolate y and leave the coefficients on the other side.

0.5x = y - 4

0.5x (+4) = y - 4 (+4)

0.5x + 4 = y

y = 0.5x + 4

Answer 2

Answer:

y=0.5x+4

Step-by-step explanation:

0.5x= y-4

add 4 on both sides

and then you get:

y=0.5x+4

Use Trigonometric substitution to eliminate the roots 1.1. 164+2 + 1 Use Trigonometric substitution to eliminate the roots 1.1. V64+2 + 1 1.2. V4z2 – 49

Answers

To eliminate the roots in 1.1 and 1.2, we can use trigonometric substitution. In 1.1, we can substitute x = 4 sin(theta) to eliminate the root of 4. In 1.2, we can substitute z = 7 sin(theta) to eliminate the root of 7.

1.1. V64+2 + 1 We can substitute x = 4 sin(theta) to eliminate the root of 4. This gives us:

V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3 1.2. V4z2 – 49

We can substitute z = 7 sin(theta) to eliminate the root of 7. This gives us:

V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta) (2 – 1) = 7 sin(theta)

Here is a more detailed explanation of the substitution:

In 1.1, we know that the root of 4 is 2. We can substitute x = 4 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 2.

When we substitute x = 4 sin(theta), the expression becomes V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3

In 1.2, we know that the root of 7 is 7/4. We can substitute z = 7 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 7/4.

When we substitute z = 7 sin(theta), the expression becomes: V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta)

i don't know how to do this​

i don't know how to do this

Answers

Step-by-step explanation:

the slope-intercept form of a line (= linear function) is

y = ax + b

"a" is the slope of the line and represents the ratio "y coordinate change / x coordinate change" when going from one point to another on the line.

"b" is the y-intercept (the y value when x = 0; in other words, the y value where the line intercepts the y axis).

so, for the slope, let's compare 2 points. and let's pick just the first 2.

(1, 8) to (2, 11).

x changes by +1 (from 1 to 2).

y changes by +3 (from 8 to 11).

so, the slope is +3/+1 = 3/1 = 3

and our equation looks like

y = 3x + b

to get b, we use one point. I pick the first one for the smallest numbers :

8 = 3×1 + b = 3 + b

5 = b

the full line equation is therefore

y = 3x + 5

The residents of a city voted on whether to raise property taxes the ratio of a yes votes to no votes was 5 to 4 if there were 4923 total votes how many yes votes were there ?

Answers

Answer:

2,735 yes votes

Step-by-step explanation:

First we have too determine the ratio of yes votes to the total number of votes.

We can rationalize thus

If there are 5 yes votes and 4 no votes, the total number of votes = 5+ 4 = 9

So 5/9th of the total votes are yes votes

If the total number of votes = 4923 , number of yes votes = 5/9 x 4923

= 2,735 yes votes       ANSWER

We can check to see if our reasoning is correct:

Total number of no votes = 4923 - 2735 = 2188

Yes votes to Nay votes = 2735 : 2188

As a fraction:
2735 / 2188 = 1.25

1.25 = 1 1/4 = 5/4 which is the ratio of yes to no votes and tallies with the question data

Answers

The difference between `a/b` and `(a/b): `The difference between `a/b` and `(a/b)` is that `a/b` denotes a fraction while `(a/b)` means the floor function of a/b.

The floor function of a number is the largest integer less than or equal to that number. Thus, `(a/b)` denotes the greatest integer that does not exceed a/b.

(i) The meaning of `a div b` and `a mod b`:

The quotient of `a` and `b` is denoted by `a div b`.

The remainder when `a` is divided by `b` is denoted by `a mod b`.

In other words, when `a` is divided by `b`, `a` leaves a remainder of `r` if `r` is between `0` and `b-1`.

Thus, `a = bq + r` where `0 ≤ r ≤ b-1`.

ii. Prove or disprove that if a, b, and d are integers with d > 0, then (a + b) div d ≤ a div d + b div d.Proof:

Let `a, b, d` be integers such that `d > 0`.

Then, `(a+b) = [(a+b) div d]d + (a+b) mod d`...(1)

`a = [a div d]d + a mod d`...(2)

`b = [b div d]d + b mod d`...(3)

Adding equations `(2)` and `(3)`, we get `a+b = [(a+b) div d]d + a mod d + b mod d`

Since `a mod d` and `b mod d` are less than `d`, it follows that `a mod d + b mod d < d`.

Therefore, `[(a+b) div d] = floor[(a+b)/d] ≤ (a+b)/d`We can substitute the above inequality in equation `(1)` and simplify to get:(a+b) div d ≤ a div d + b div d + 1This shows that `(a+b) div d ≤ a div d + b div d` is true in general.

A cylinder is sliced in such a way that the plane cuts in a direction perpendicular to the base,what is the resulting cross section?

Answers

If a cylinder is sliced in a direction perpendicular to the base, the resulting cross section would be a rectangle.

A cylinder has a circular base, and a perpendicular slice would cut through the circular base and create a flat rectangular shape.

To visualize this, imagine a cylinder as a can of soup. If you were to cut the can of soup straight down the middle, perpendicular to the base, you would create a cross section that is a rectangle. This rectangular cross section would have a width and a length, which would be equal to the diameter of the circular base of the cylinder.

In geometry, a rectangle is defined as a quadrilateral with four right angles, and opposite sides that are equal in length. Therefore, a rectangular cross section of a cylinder would also have these properties.

In summary, if a cylinder is sliced in a direction perpendicular to the base, the resulting cross section would be a rectangle with equal width and length, and four right angles.

Find the value of each variable using sine and cosine. Round your answers to the nearest tenth.s = 31.3, t = 13.3

Answers

The value of sin(θ) is approximately 0.921 and the value of cos(θ) is approximately 0.391.

To find the value of each variable using sine and cosine, we need to set up a right triangle with the given information. Let's label the sides of the triangle as follows:

s = 31.3 (opposite side)t = 13.3 (adjacent side)h (hypotenuse)

Using the Pythagorean theorem, we can find the length of the hypotenuse:

h2 = s2 + t2

h2 = 31.32 + 13.32

h2 = 979.69 + 176.89

h2 = 1156.58

h = √1156.58

h ≈ 34.0

Now that we know the length of the hypotenuse, we can use sine and cosine to find the values of the variables:

sin(θ) = s / h

sin(θ) = 31.3 / 34.0

sin(θ) ≈ 0.921

cos(θ) = t / h

cos(θ) = 13.3 / 34.0

cos(θ) ≈ 0.391

why is it necessary to apply the finite population correction factor when a sample is a significant part of the population? multiple choice question. if a sample is a larger part of the population, it will give a better estimate. if a sample is a larger part of the population, it will give a less accurate estimate. for a small population, samples are not independent, and thus give less accurate results.

Answers

When taking a sample from a finite population, it is important to consider the size of the sample relative to the size of the population.

If the sample is a significant part of the population, meaning that it represents a large proportion of the total population, then the finite population correction factor needs to be applied to adjust for the reduced variance in the estimate. The reason for this is that as the sample size approaches the population size, the variability in the estimate decreases. This is because the sample becomes less representative of the population and more reflective of the population itself. Therefore, the standard error of the estimate decreases, making it necessary to apply the correction factor to account for this. If the correction factor is not applied, the standard error of the estimate will be underestimated, leading to confidence intervals that are too narrow and hypothesis tests that are overly confident. This can result in incorrect conclusions being drawn from the data. It is important to note that the need for the finite population correction factor is not dependent on the accuracy of the estimate. Even if the sample is a larger part of the population and gives a better estimate, the correction factor must still be applied to account for the reduced variance in the estimate. In summary, the finite population correction factor is necessary when the sample is a significant part of the population to adjust for the reduced variance in the estimate. This ensures that confidence intervals and hypothesis tests are accurate and correct conclusions can be drawn from the data.

a. A forecaster expresses confidence that there is an 80 percent chance of precipitation in the forecasted area, and it is expected to produce measurable precipitation over 90 percent of the area.
b. A forecaster expresses confidence that there is a 20 percent chance of precipitation in the forecasted area, and it is expected to produce measurable precipitation over 10 percent of the area.

Answers

The correct answer is a) the probability of precipitation is 72%. and b)  the probability of precipitation is 2%.

The given formula to determine the probability of precipitation (PoP) is PoP = (C * A) * 100 percent where C represents the confidence that precipitation will occur somewhere in the forecasted area and A represents the percentage of the area that will receive measured precipitation if it occurs.

(a) If a forecaster expresses confidence that there is an 80% chance of precipitation in the forecasted area, and it is expected to produce measurable precipitation over 90% of the area, then the probability of precipitation is given as follows: PoP = (C * A) * 100 per cent C = 80%A = 90%PoP = (80% * 90%) * 100%

PoP = 72%.

Therefore, the probability of precipitation is 72%.

(b) If a forecaster expresses confidence that there is a 20% chance of precipitation in the forecasted area, and it is expected to produce measurable precipitation over 10% of the area, then the probability of precipitation is given as follows: PoP = (C * A) * 100 per cent C = 20%A = 10%PoP = (20% * 10%) * 100%PoP = 2%

Therefore, the probability of precipitation is 2%.

a rectangular tank that is 1372 ft3 with a square base and open top is to be constructed of sheet steel of a given thickness. find the dimensions of the tank with minimum weight

Answers

The dimensions of the tank with minimum  weight  is height= 7 and width and length= 14.

The minimum surface area implies that the tank has minimum weight.

Given that the base is square, its width is equal to its length.

Let x= the base width and length of the tank.

Let h = the height .

We are given the volume of the tank that is 1372 ft^3. The formula is given by

V = hx^2

We're given that V = 1,372 ft^3, so

hx^2 = 1,372

h = 1,372 / x^2  ----------(equation 1)

Surface area can be calculated using the below given formula.

A = x^2 + 4xh

Substituting the value of euation 1, h in A, we get,

A = x^2 + 4x(1,372 / x^2)

= x^2 + 5,488 / x

To get the minimum surface area to get the minimum weight, we need to differentiate  A with respect to x and equate it to zero.

dA/dx = 2x - 5,488 / x^2 = 0

2x^3 - 5,488 = 0

x =\(\sqrt[3]{\frac{5,488}{2} }\)

x= 14

We got the value of x, we substitute the value in equation 1, we get the value of h.

h = 1,372 / 14^2

h= 7

So, the dimensions of the tank with minimum weight are width and length is 14 and height is 7.
