Rate by which change in the area of the circle when radius is 2 inches with the given given rate of change of circumference is equal to 8 inches per second.

As given in the question,

Let 'r' be the radius of the circle

And 'A' be the area of the circle

Circumference of a circle 'C' = 2πr

Rate of change of circumference dC/dr = 4 inches per second

C = 2πr

⇒dC/dr = 2π(dr/dt)

⇒4 = 2π(dr/dt)

⇒(dr/dt) = 2 / π

Area of the circle 'A' = πr²

⇒dA/dt = 2πr (dr/dt)

When r = 2inches and dr/dt = 2/π

⇒dA/dt = 2π × 2 × ( 2 / π )

⇒dA/dt = 8 inches per second

Therefore, the rate of change of area of the circle when radius is 2 inches is equal to 8 inches per second.

Answer:

A

2x−6y=−12

Step-by-step explanation:

The area in square meters will the oil slick cover is 9.5×10⁶ m².

15 barrels of diesel spilt into the ocean, where each barrel contains 42 gallons. Thereby the total volume of the oil spilt by 15 barrels is calculated as follows:

The total volume of the oil spilt by 15 barrels = 15× 42 gallons.

=630 gallons

1 gallon = 3.78541 liters

Volume in L = 630 gallons × 3.78541 liters/ 1 gallon

= 2384.8083 L

1 L = 10⁻³ m³

2384.8083  L = 2384.8083 × 10⁻³ m³

= 2.3848083 m³

The area covered by the oil spill has to be determined, where the thickness of the oil spill is given to be 2.5×10² nm.

1 nm = 10⁻⁹ m

Thereby, 2.5×10² nm = 2.5×10²×10⁻⁹ m

= 2.5×10⁻⁷ m

Area (m²) = volume (m³)/thickness (m)

= 2.3848083 m³/ 2.5×10⁻⁷ m

= 0.95392×10⁷ m²

= 9.5×10⁶ m²

The rate at which the area of the triangle is changing when the base of the ladder is 9 ft from the wall will be the negative 8/3.

The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.

A 15-foot ladder is leaning against a wall of a house.

The base of the ladder is pulled away from the wall at a rate of 2ft/sec.

Then the equation will be

x² + y² = 15²

x² + y² = 225

Differentiate with respect to time. Then we have

2x (2) + 2yy' = 0

y' = -2x / y

Then the rate at which the area of the triangle is changing when the base of the ladder is 9 ft from the wall will be

Then the value of x will be

x² + 9² = 15²

x² + 81 = 225

      x² = 144

        x = 12 ft

Then the rate will be

Answer:

The correct option is;

A'(4, 4), B'(0, 4), C'(8, 8).

Step-by-step explanation:

The beginning coordinates are;

A -2, 2

B - 0, 2

C - 4, 4

Given that triangle ABC is dilated by 2, the center of dilation being the origin, (0, 0), we have;

Given that the center of dilation is the origin, we multiply the x, and y values by the scale factor as follows;

(x, y) → (2·x, 2·y)

Which gives;

A - (2, 2) → A'(2×2, 2×2) = A'(4, 4)

B - (0, 2) → B'(2×0, 2×2) = B'(0, 4)

C - (4, 4) → C'(2×4, 2×4) = C'(8, 8)

The correct option is A'(4, 4), B'(0, 4), C'(8, 8).

The variability computed as the sum of the squared errors, or SSE, for all values of the response variable in a one-way ANOVA is known as the error sum of squares.

This measure of variability gives an indication of the amount of variation within the sample being tested, by measuring the differences between each value of the response variable and the mean value of the response variable. This can be expressed mathematically as:

SSE = Σ(yi - μ)2 where yi represents the ith response value, and μ represents the mean of the response values.


The error sum of squares is then used to calculate the mean square error, or MSE, which is a measure of the variance in the error. The MSE is calculated by dividing the SSE by the number of observations in the sample. The MSE can be expressed mathematically as:

MSE = SSE/N where N is the number of observations in the sample.


The MSE is then used to calculate the F-statistic, which is a measure of the difference between the sample means and the population mean. The F-statistic can be expressed mathematically as:

F-statistic = MSE/σ2 where σ2 is the population variance.


The error sum of squares is therefore a key measure of variability used in one-way ANOVA, and is used to calculate the MSE and F-statistic.

Answer:

y < 1/4x + 3

Step-by-step explanation:

the line is dotted so we know the symbol will not include the "equal to" part

we can also see that the shading in below the y intercept, so we know that the symbol will also be less than

this means the symbol is <

now, create an equation for the line:

we know that the y intercept is 3, and that there is a rise of 1 and a walk of 4

so the slope is 1/4

now put this together and you get 1/4x + 3

this part will go on the right side of the < symbol in your inequality

so now you can create an inequality: y < 1/4x + 3

Answer:

y < \(\frac{1}{4}\) x + 3

Step-by-step explanation:

m = \(\frac{1}{4}\) and coordinates of y-intercept are (0, 3)

y < \(\frac{1}{4}\) x + 3

Step-by-step explanation:

The wind has a speed of w and a direction α with the vertical.  The x component of that speed is w sin α.  The y component is -w cos α.

In order to stay on the north trajectory AB, the plane must have a horizontal speed of -w sin α.  The plane's speed is v, so using Pythagorean theorem, the y component of the plane's speed is:

v² = (-w sin α)² + vᵧ²

v² = w² sin²α + vᵧ²

vᵧ = √(v² − w² sin²α)

The total vertical speed is therefore √(v² − w² sin²α) − w cos α.

If a is the length of AB, then the time is:

t = a / [√(v² − w² sin²α) − w cos α]

To rationalize the denominator, we multiply by the conjugate.

t = a / [√(v² − w² sin²α) − w cos α] × [√(v² − w² sin²α) + w cos α] / [√(v² − w² sin²α) + w cos α]

t = a [√(v² − w² sin²α) + w cos α] / (v² − w² sin²α − w² cos²α)

t = a [√(v² − w² sin²α) + w cos α] / (v² − w²)

The above statement is False.

The correct Statement is :

The linear regression line has an equation of the form Y =a + bX

where, Y is called the dependent variable or response.

X means independent or predictor or explanatory variable.

a is the y-intercept and b is the slope of the line.

Regression Line:

A regression line is a statistical tool that shows the correlation between two variables. Specifically, it is used when the variation of one (the dependent variable) depends on changes in the value of the other (the independent variable).

Simple linear regression has two cases:

The formula for the least squares regression line (LSRL) from Y to X is:

                           Y=a + bX + ɛ

where,

Y is the dependent variable.

a is the Y intersection.

b is the slope of the regression line.

X is the independent variable.

ɛ is the residual (error).

and

b = (N∑XY-(∑X)(∑Y) / (N∑X2– (∑X)2) ;

and

a = (∑Y – b ∑X) / N

where, N is the total number of observations.

The inequality describes the problem of a local ice cream shop has a parking lot with enough space for 18 cars is x + 7 ≤ 18

In mathematics, an inequality describes a relationship between two values of an algebraic expression that are not equal. “If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then, this relationship is called an inequality." For example, x>8 (x should be greater than 8).

We have, a local ice-cream shop has a parking lot with enough space.

The maximum number of cars will be parked in parking lot = 18.

At right now, the number of cars in parking lot= 7. Let assume that x be number of more cars can park in the lot. We have to express this in form of an Inequality. Total cars in parking lot = 7 + x but this number of cars cannot exceed the 18 , so x + 7 ≤ 18

Hence, required Inequality is x + 7 ≤ 18.

Step-by-step explanation:

The size of the two replacement payments is $373.67.

Calculate the present value of the first payment. This is the amount of money that would be needed today to have the same amount of money in the future, after taking into account interest. The formula for calculating the present value of a payment is:

Present Value = Future Value / (1 + Interest Rate)^Time

In this case, the future value is $423, the interest rate is 4.4% compounded quarterly, and the time is 1 year. So, the present value of the first payment is:

Present Value = 423 / (1 + 0.044/4)^1 = 400.00

Calculate the present value of the second payment.

This is calculated in the same way as the present value of the first payment. The future value is $723, the interest rate is 4.4% compounded quarterly, and the time is 8 years. So, the present value of the second payment is:

Present Value = 723 / (1 + 0.044/4)^8 = 347.34

Calculate the size of the two replacement payments. This is done by taking the sum of the present values of the two payments, and dividing by 2. So, the size of the two replacement payments is:

Replacement Payment = (400.00 + 347.34) / 2 = 373.67

Therefore, the size of the two replacement payments is $373.67.

In statistics, p represents the true proportion p hat represents the sample proportion

p represents population that has a certain characteristic or falls into a certain category. It is a fixed, unknown value that we are trying to estimate.

p hat represents the sample proportion, which is an estimate of the true proportion based on a sample of the population. It is calculated by dividing the number of individuals in the sample with the characteristic or in the category by the total sample size.

For example, if we want to estimate the proportion of students who prefer chocolate ice cream, we could take a sample of 100 students and find that 60 of them prefer chocolate.

In this case, p hat would be 60/100 or 0.6. This is our estimate of the true proportion, p, of all students who prefer chocolate ice cream.

The probability that I will end up with one card from each suit is 3/32 when I choose four cards from a standard-card deck, with replacement. This can be obtained by finding probability of each draw.

⇒ 52 cards - 13 cards (1 suite) = 39 cards (remaining 3 suites)

On the second draw, we have a (39/52)  = (3/4)  probability of drawing a different suite from the first draw

⇒ 52 cards - 26 cards (2 suite) = 26 cards (remaining 2 suites)

On the third draw we have a (26/52) = (1/2) probability of drawing a suite different from the first two draws

⇒ 52 cards - 39 cards (3 suite) = 13 cards (remaining 1 suites)

On the last draw we  have a (13/52) = (1/4) probability of drawing a different suite from the ones we  drew on the first three draws

So  the probability = (1) (3/4) (1/2) (1/4) = 3/32

Hence the probability that I will end up with one card from each suit is 3/32 when I choose four cards from a standard-card deck, with replacement.

The coordinates of an undefined slope are points that are either the same or have no x-value. In both cases, the slope of a line between these points would be undefined because it would involve dividing by 0, which is not allowed in mathematics. This is because the slope of a line is calculated by dividing the difference in y-coordinates by the difference in x-coordinates, and if the x-coordinates are the same or do not exist, this division would result in an undefined value.
