Find the 64th tent of the arithmetic sequence -3, -14 -25.

Answer:

It is difficult to give a precise answer without more information, such as the thickness of the sauce and the desired coverage. However, if we assume that the sauce is being applied evenly and that a thin layer is desired, the amount of sauce needed to cover a 16" pizza would be approximately 50.24 in2. This is because the area of a circle with a diameter of 16" is approximately 50.24 in2. To calculate the area of a circle, you can use the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius of the circle (which is half the diameter). In this case, the radius would be 8" and the area would be approximately 50.24 in2.

Using the slope formula, the required equation is y = -4x + 1.

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.

The slope of a line can be used to gauge how steep it is.

The slope is theoretically determined as "rise over run" (change in y divided by change in x).

So, slope formula: m = y2 - y1/x2 - x2

Now we have: y = - 1/4 x + 6 and points (2, 9)

Now, substitute as follows:

(y-9) = -4(x+2)

In order to convert this equation into the slope-internet form, we can additionally solve it for y:

(y-9) = (-4*x+(4*2)

(y-9) = -4x - 8

y - 9 + 9 = -4x - 8 + 9

y - 0 = -4x + 1

y = -4x + 1

Therefore, using the slope formula, the required equation is y = -4x + 1.

Dilatation is acutally for medicine and dilation is actually for phycology.

After the discount and the tax, the total cost will be $24.19

So, suppose we have a known price P.

If we apply a discount of X (in percentage) then the new price will be:

P' = P*(1 - X/100%)

If instead, we apply an increase of X, the new price willbe:

P' = P*(1 + X/100%).

In this case the original price is $30, then we apply a discount of 25% and then an increases of 7.5%, then the total cost will be:

C = $30*(1 + 7.5%/100%)*(1 - 25%/100%)

The term "standard error of the mean" refers to the sample mean's standard deviation. And the formula for the standard deviation is σ/√n.

The square root of a random variable's variance is the standard deviation of a sample, statistical population, data collection, or probability distribution. Compared to the average absolute deviation, it is algebraically easier but less reliable in practice. The standard deviation has the advantage of being represented in the same unit as the data, unlike the variance, which is a desirable characteristic.

The standard error of a statistic (such the sample mean) is related to the standard deviation of a population or sample, however they are very different. Standard deviation of the population divided by the square root of sample size yields the standard deviation of the sampling distribution of means. "Standard error of the mean" is the term for the sampling distribution's standard deviation.

percent decrease of water in the​ tank?

A tank contained 6 in of water.

After several hours, it contained 3 in of water

Answer: The correct answer is A. Addition

Step-by-step explanation:

Let's solve for x in 2x+4y=10

Step 1: Add -4y to both sides.

2x+4y+−4y=10+−4y

2x=−4y+10

Step 2: Divide both sides by 2.

2x/2 = −4y+10/2

x = −2y +5

Now let's solve for x in 5x+4y = -12

Step 1: Add -4y to both sides.

5x+4y+−4y=−12+−4y

5x=−4y−12

Step 2: Divide both sides by 5.

5x/5 = −4y−12/5

x = −4/5y + −12/5

Here is what solving for Y looks like

If the numbers denoting the perimeter and area of the square are equal, the length of the diagonal will be 4√2 units.

What are Area and Perimeter?

An object's shape defines a region as its area. The area of a figure or any other two-dimensional geometric shape is how much space it takes up in a plane.

The whole length encircling a shape is referred to as its perimeter. Simply put, if a shape is stretched into a linear form, its perimeter is its length. In a two-dimensional plane, a shape's perimeter is the sum of its total dimensions.

Let the side of the square to be 'a'.

If Area and Perimeter of a square are equal then,

So,  Area = Perimeter

      a^2 = 4a

we get, a = 4 units.

Now, we can find the diagonal by using Pythagoras theorem,

We know that, Hypotenuse^2 = Base^2 + Perpendicular^2

Here, the hypotenuse will be the diagonal of the square.

So, We have,

            Diagonal^2 = 4^2 + 4^2

Answer:

In the linear function equation y = -7x + 1, the value of m (the slope of the line) is -7. The slope of a line represents the rate at which the y-value changes as the x-value changes. In this case, for every unit increase in the x-value, the y-value decreases by 7 units. Therefore, the function has a rate of -7.

To find the slope of a line from a linear function equation, you can use the formula m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are two points on the line. In this case, we can choose any two points on the line and substitute their coordinates into the formula to find the slope. For example, if we choose the points (1, -6) and (2, -13), we get:

m = (-13 - (-6)) / (2 - 1) = -7

Alternatively, we can use the fact that the slope of a line is equal to the coefficient of the x-term in the linear function equation. In this case, the coefficient of the x-term is -7, so the slope of the line is also -7.

o answer this question, we need to apply the transformations in the reverse order. So first, we need to apply the translation according to the rule (x+3,y-3). This means that the coordinates of the triangle will become A'(7,2), B'(0,3), and C'(2,5). Next, we need to reflect the triangle across the line y=0. This means that the y-coordinates of the triangle will become negative. So the coordinates of the triangle will become A''(7,-2), B''(0,-3), and C''(2,-5). Finally, we need to rotate the triangle 90 degrees. In a standard cartesian coordinate system, a rotation of 90 degrees counterclockwise is equivalent to the transformation (x, y) -> (-y, x). So the final coordinates of the triangle will be A'''(-2,7), B'''(-3,0), and C'''(-5,2).
