She has 7 gallons of gas after driving for 2 hours.

What is Subtraction?

Subtraction is a mathematical operation that involves finding the difference between two numbers or quantities. It is the inverse of addition, which means that it is the opposite process of adding numbers.

In subtraction, a number or quantity (called the subtrahend) is subtracted from another number or quantity (called the minuend), resulting in the difference. The symbol used for subtraction is "-" and the resulting value is called the remainder or difference.

Katie had 12 gallons of gas.

She used 2 1/2 gallons of gas each hour.

Now, She drove 2 hours.

So, gallon of gas use for 2 hours = 2 × 2 1/2

                                                       = 2 × 5/2

                                                       = 5 gallons of gas.

Now, Gallons of gas left after 2 hours

        = total gallons of gas - Gallons used for 2 hours

        = 12 - 5

        = 7.

Hence, She is left with 7 (12-5) gallons of gas.

Answer:

We know that the formula for the circumference (C) of a circle is:

C = 2πr

where r is the radius of the circle.

We are given that the circumference is 8πm, so we can write:

8πm = 2πr

Simplifying this equation by dividing both sides by 2π, we get:

r = 4m

Now that we know the radius of the circle, we can use the formula for the area (A) of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(4m)^2

Simplifying this equation, we get:

A = π(16m^2)

A = 16πm^2

Therefore, the area of the circle is 16πm^2. The answer is C

From the quadratic equation, we found the new dimensions:

Length =  14.85 feet

Width = 18.85 feet.

What is a quadratic equation?

The polynomial equations of degree two in one variable of type

f(x) = ax² + bx + c = 0 and with a, b, c, ∈ R and a ≠ 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" is for the absolute term of

f (x).

The current dimensions of the farm are 10 feet by 14 feet.

Length l = 10 feet

Width w = 14 feet

Area a = l * w = 10 * 14 = 140 sq. feet.

Now the new area is doubled.

A = 2a = 2 * 140 = 280 sq.feet

The new dimensions are:

L = l + x = 10 + x

W = w + x = 14 +x

A = (10+x)(14+x)

280 = 140 + 10x + 14x + x²

x² + 24x - 140 = 0

This is a quadratic equation.

Solving the equation, we get

x = 4.85, -28.85

Neglecting the negative value, we get the value of x as 4.85.

Therefore from the quadratic equation, we found the new dimensions:

L = 10 + 4.85 = 14.85 feet

W = 14 + x = 14 + 4.85 = 18.85 feet.

given

The steps to determine the equivalent production are as follows:

Total units input: 8000

A typical loss is 400 units, or 5% of 8000 units.

Consider there to be no anomalous loss because none has been reported.

Counted in total units: 8000 - 400 = 7600 units

Units completed: 7600 less 1000 (closing WIP) equals 6600 units.

Equivalent production equals completed units plus closing WIP multiplied by the percentage of completion, which equals 6600 + 1000 x 60%, or 6600 + 600, or 7200 units.

Hence, 7200 units were produced throughout the period equivalently as WIP multiplied by the percentage of completion.

Answer: To construct a 99% confidence interval for the mean number of books people read, we can use the following formula:

CI = X ± Z*(S/sqrt(n))

where:

X = sample mean (11.3)

S = sample standard deviation (16.6)

n = sample size (1005)

Z = the z-score for the confidence level (99%)

To find the z-score for the 99% confidence level, we can look up the value in a standard normal distribution table or use a calculator. The z-score for a 99% confidence level is 2.576.

Substituting the values into the formula, we get:

CI = 11.3 ± 2.576*(16.6/sqrt(1005))

CI = 11.3 ± 2.576*(0.524)

CI = 11.3 ± 1.35

Therefore, the 99% confidence interval for the mean number of books people read is (9.95, 12.65). We can be 99% confident that the true population mean falls within this interval.

Therefore, the general solution for the differential equation dy/dx cosx=ysinx+sin113x is y = log |sin(x) / sin(113x)| + C, where C is an arbitrary constant.

A differential equation explains the unknown derivative or derivatives of a function. Example: Think about the equation. The equation d y d x = x sin represents the derivative of an unknown function.

We can solve this differential equation by using separation of variables.

First, we'll rearrange the equation to isolate the y term on one side:

cos x = y sin x + sin 113x

cos x - sin 113x = y sin x

y = (cos x - sin 113x) / sin x

Now we can integrate both sides with respect to x:

∫dy = ∫(cos x - sin 113x) / sin x dx

Using integration by parts, we can integrate the second term on the right side:

∫dy = ∫cos x / sin x dx - ∫sin 113x / sin x dx

The first term on the right side can be integrated using substitution:

u = sin x, du/dx = cos x dx

∫cos x / sin x dx = ∫du/u = log |u| + C1 = log |sin x| + C1

The second term on the right side can be rewritten as:

∫sin 113x / sin x dx = - ∫sin 113x / sin 113x cos x dx

= - ∫csc x cos 113x dx

Using substitution again:

u = sin 113x, du/dx = 113 cos 113x dx

∫csc x cos 113x dx = - ∫du/u = - log |sin 113x| + C2

y = log |sin x| - log |sin 113x| + C

Simplifying:

y = log |sin(x) / sin(113x)| + C

Therefore, the general solution for the differential equation dy/dx cosx=ysinx+sin113x is y = log |sin(x) / sin(113x)| + C, where C is an arbitrary constant.

Step-by-step explanation:

The given sequence is a geometric sequence, where the common ratio (r) between any two consecutive terms is:

r = 3/1.5 = 2

We need to find the sum of the first 10 terms of this sequence. Let's denote the first term (a₁) as 1.5 and the tenth term (a₁₀) as a.

The formula to find the sum of the first n terms of a geometric sequence is:

Sₙ = a(1 - rⁿ)/(1 - r)

Substituting the values, we get:

a = 1.5 x 2^9 = 768

S₁₀ = 1.5(1 - 2¹⁰)/(1 - 2) = 1.5(1 - 1024)/(-1) = 1.5 x 1023

Function is increasing in the domain of interval (1, ∞).

A quadratic function is a mathematical function of the form:

f(x) = ax² + bx + c

where "a", "b", and "c" are constants, and "x" is the variable.

From the given table of ordered pairs, we can see that the function k is a continuous quadratic function that passes through the points (-1, 0), (0, 2), (2, 5), (3, 4), and (4, 5).

We can estimate the slope of the function between each pair of consecutive points in the table. For example, between (-1, 0) and (0, 2), the slope is positive, so the function is increasing in the interval (-1, 0). Between (0, 2) and (2, 5), the slope is also positive, so the function is increasing in the interval (0, 2). However, between (2, 5) and (3, 4), the slope is negative, so the function is decreasing in the interval (2, 3).

Finally, between (3, 4) and (4, 5), the slope is positive, so the function is increasing in the interval (3, 4). Therefore, the function k is increasing over the intervals (-1, 0) and (3, 4).

So, the correct answer is option A: (1, ∞).
