In the XY plane, the circles with equations (x-3) + y = 11 and (x+2) + y = r are externally tangent. the value of r is -6.

Generally, To find the value of r, we can start by solving for the centers and radii of the two circles.

The equation of the first circle is of the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. We can rewrite the equation of the first circle as (x - 3)² + y² = 11², so the center of the circle is (3, 0) and the radius is 11.

The equation of the second circle is also of the form (x - h)₂ + (y - k)₂ = r². We can rewrite the equation of the second circle as (x + 2)² + y² = r², so the center of the circle is (-2, 0) and the radius is r.

Since the two circles are externally tangent, the distance between their centers is equal to the sum of their radii. Therefore, the distance between the centers is equal to 11 + r. We can use the distance formula to find the distance between the centers:

distance = √((h₂ - h₁)^2 + (k₂ - k₁)²)

Plugging in the coordinates of the centers, we get:

distance = √((-2 - 3)^2 + (0 - 0)^2) = √(5^2 + 0^2) = √(25) = 5

Since the distance between the centers is equal to the sum of the radii, we can set up the equation:

5 = 11 + r

Solving for r, we get:

r = 5 - 11 = -6

Therefore, the value of r is -6.

Answer:2 2/3 or 8/3

Step-by-step explanation:

The equation of a line y=2x+8.

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in the value of y on the vertical axis/change in the value of x on the horizontal axis

Looking at the given line,

y = 2x + 7

Compared with the slope-intercept equation,

Slope, m = 2

If a line is parallel to another line, it means that both lines have equal or the same slope. This means that the slope of the line passing through the point (-2, 4) is 2

Substituting m= 2, y = 4 and x = -2 into the equation, y = mx + c , it becomes

4 = 2 × - 2 + c

4 = - 4 + c

c = 4 + 4 = 8

The equation becomes y=2x+8.

Answer:

Slope will be -1/6 (change sign and take the reciprocal) since its perpendicular

Slope intercept form: y=mx+b

5 = -1/6(4) + b

The average value of the function f(x) = x^3e^(-x^4) on the interval [0, 9] is approximately 0.129.

To find the average value of a function on an interval, we need to compute the definite integral of the function over that interval and then divide it by the length of the interval. In this case, we want to find the average value of f(x) = x^3e^(-x^4) on the interval [0, 9].

First, we integrate the function over the interval [0, 9]:

∫[0, 9] x^3e^(-x^4) dx

Unfortunately, there is no elementary antiderivative for this function, so we have to resort to numerical methods. Using numerical integration techniques like Simpson's rule or the trapezoidal rule, we can approximate the integral:

∫[0, 9] x^3e^(-x^4) dx ≈ 0.129

Finally, to find the average value, we divide this approximate integral by the length of the interval, which is 9 - 0 = 9:

Average value ≈ 0.129 / 9 ≈ 0.0143

Therefore, the average value of f(x) = x^3e^(-x^4) on the interval [0, 9] is approximately 0.129.

Answer:

50h+25.5=154

Step-by-step explanation:

The retailer paid approximately $29,916.15 for the good after applying both the trade and cash discounts.

To calculate the final amount the retailer paid after the trade and cash discounts, we need to apply the discounts one after the other.

First, the retailer received a trade discount of 15%. This means the retailer only needs to pay 100% - 15% = 85% of the marked price.

So, the amount after the trade discount is 85% of the market price:

Trade discount amount = 0.85 * 37450 = 31832.5

Now, the retailer receives a cash discount of 6% on the remaining amount. This means the retailer only needs to pay 100% - 6% = 94% of the trade discount amount.

So, the final amount after the cash discount is 94% of the trade discount amount:

Cash discount amount = 0.94 * 31832.5 = 29916.15

Therefore, the retailer paid approximately $29,916.15 for the good after applying both the trade and cash discounts.

Since the given expression can be factored in the form (2t+1) and (t+2) so 2t² + 5t + 2 cannot be a prime number.

A whole number greater than 1 that has no factor other than 1 and the number itself is called a prime number.

Some examples of prime numbers are 3,11,19 ... all these numbers can only be divided by 1 or the number itself so they are called prime.

In the given expression 2t² + 5t + 2 , it is said that t is positive whole number. So if t is a positive whole number then the expression can be written as another positive whole number.

Now the expression 2t² + 5t + 2  can be factored into two smaller factors.

2t² + 5t + 2

= 2t² + 4t + t + 2

= 2t (t + 2 )+1 (t+2)

= (t+2) (2t+1)

If t is a positive whole number then t+2 is a whole number and 2t+1 is another positive whole number.

Hence these two numbers are factors of 2t² + 5t + 2 . But a prime number does not have any factors.

So 2t² + 5t + 2  is not a prime number.

Step-by-step explanation:

The equation of the normal to the curve is

( Y - \(e^{-3}\) - 1/\(e^{-3}\) ) / ( X - \(e^{-3}\) ) = 1/3

An equation contains one or more than two terms connected by an equal sign.

Example:

2x + 4y = 88 is an equation.

We have,

Equation of the curve:

y(x) = x + 1/x ______(1)

And,

y = -3x is parallel to the tangent.

This means,

y = -3x is in the form of y = mx + c

So,

Slope = m = dy/dx

m = -3 ______(2)

Now,

y = x + 1/x

dy/dx = 1 + logx

-3 = 1 + logx

-3 - 1 = logx

-3 = logx

\(e^{-3}\) = \(e^{logx}\)

x = \(e^{-3}\) ______(3)

Now,

The equation of the normal.

( Y - y(x) ) / (X - x) = -1/(dy/dx)

So,

From (1), (2), and (3)

( Y - y(\(e^{-3}\)) ) / (X - \(e^{-3}\)) = -1/-3

( Y - (\(e^{-3}\) + 1/\(e^{-3}\)) / ( X - \(e^{-3}\) ) = 1/3

( Y - \(e^{-3}\) - 1/\(e^{-3}\) ) / ( X - \(e^{-3}\) ) = 1/3

Thus,

The equation of the normal to the curve is

( Y - \(e^{-3}\) - 1/\(e^{-3}\) ) / ( X - \(e^{-3}\) ) = 1/3

The cost need to put a 0. 5 ft layer of topsoil on the entire garden is $1000

According to the given statement

we have given that the

side length of the square garden is 10ft.

topsoil cost per foot is $5

And we have to find the cost which required to put a 0. 5 ft layer of topsoil on the entire garden.

So,

The  side length of the square garden is 10ft.

Now, the volume of the cube is (a)^2

And

Total volume of cube = 10*10

Total volume of cube = 100 per square foot.

Now, we find the cost required for a topsoil.

Cost required to put a topsoil of 1 foot in the total volume of cube = volume*cost

So,

Cost required to put a topsoil of 1 foot in the total volume of cube = 1000*5

Cost required to put a topsoil of 1 foot in the total volume of cube = $5000

if we put a topsoil of 0.5 feet then

The cost required = $5000/0.5

The cost required = $1000.

An approximate size which does not represent any of the actual dimensions of the unit is nominal value.

The phrase "nominal number" is said to be quite new and rarely used. It seems to have come from the statistical phrase "nominal data," which is reportedly defined as data revealing "...merely declarations of qualitative category of membership," as it is used in school textbooks. The meaning of the word "nominal" in this use is "name."

Nominal numbering is mathematically a one-to-one and onto function from a set of named objects to a set of numbers, which may change (typically growing) over time. It is a function because each named object is assigned a single number; it is one-to-one because different objects are assigned different numbers; and it is onto because every number in the set at a given time has a single named object associated with it.

Complement of set A is the set of all elements in the universal set that are not in the set .

If there is a subset of the universal set (U) called A, then the complement of set A, denoted by the symbol A', is different from the elements of set A and contains the elements of the universal set but not the elements of set A.

In this case, A' = x U: x A.

In other words, the complement of a set A is the difference between the universal set and set A.

For example: U = {1, 2, 3, 5, 7, 9, 15 ,14, 13}, A = {1, 2, 3, 5,7,9}, find the complement of A.

A' = U - A = {1, 2, 3, 5, 7, 9, 15,14,13} - {1, 2, 3, 5,7,9} = {15,14, 13}

A set that contains items from all related sets, without any repetition of elements, is known as a universal set (often symbolised by the letter U). If A and B are two sets, for example, A = 1, 2, 3 and B = 1, a, b, c, then U = 1, 2, 3, a, b, c is the universal set that these two sets belong to.
