The inverse function B(a) is given by B(a) = (2a - 70) / 10

We have,

To find the inverse function B(a) that takes the trapezoid's area as input and returns the length of the other base, we need to swap the roles of the variables in function A(b) and solve for the variable that was originally the input.

So,

Given A(b) = (10 x (b + 7)) / 2, where b represents the length of the other base, we can solve for b in terms of the trapezoid's area a:

a = (10 x (b + 7)) / 2

To find B(a), we can rearrange the equation to solve for b:

2a = 10 x (b + 7)

2a = 10b + 70

10b = 2a - 70

b = (2a - 70) / 10

Thus,

The inverse function B(a) is given by B(a) = (2a - 70) / 10

The distance between the points (-6,7) and (-1,1) is  7.81 units

We know that the distance formula between two points (x₁, y₁) and (x₂, y₂) is:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

We need to find the distance between the points (-6,7) and (-1,1)

Let (x₁, y₁) = (-6, 7)

and (x₂, y₂) = (-1, 1)

Using above distance formula, the distance between the points (-6,7) and (-1,1) would be,

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(1 - 7)² + (-1 - (-6))²]

d = √[(1 - 7)² + (-1 + 6)²]

d = √[(-6)² + (5)²]

d = √[36 + 25]

d = √(61)

d = 7.81 units

The National League variance is 0.00020 and the standard deviation is 0.0141 while the American League variance is 0.000191 and the standard deviation is 0.0138.

According to question, the team batting averages for Major League Baseball in a certain year are represented below. We have to find the variance and standard deviation for each league. Given below is the table of team batting averages in National League and American League.

National League   American League
 .240                .237
 .242                .244
 .240                .251
 .247                .233
 .256                .243
 .249                .248
 .256                .238
 .240                .241
 .243                .250
 .237                .238

We know that,

variance = (1/N)* Σ(xi - µ)²
Standard deviation = √variance

National League:
The mean of National League, µ = (0.240 + 0.242 + 0.240 + 0.247 + 0.256 + 0.249 + 0.256 + 0.240 + 0.243 + 0.237)/10 = 2.443/10 = 0.2443.
Substitute the values in the formula, variance = (1/10)* Σ(xi - µ)² = (1/10)* [ (0.240 - 0.2443)² + (0.242 - 0.2443)² + (0.240 - 0.2443)² + (0.247 - 0.2443)² + (0.256 - 0.2443)² + (0.249 - 0.2443)² + (0.256 - 0.2443)² + (0.240 - 0.2443)² + (0.243 - 0.2443)² + (0.237 - 0.2443)² ]= 0.00019749
Standard deviation = √variance = √0.00019749 = 0.01405
The National League variance is 0.00020 and the standard deviation is 0.0141

American League:
The mean of American League, µ = (0.237 + 0.244 + 0.251 + 0.233 + 0.243 + 0.248 + 0.238 + 0.241 + 0.250 + 0.238)/10 = 2.423/10 = 0.2423
Substitute the values in the formula, variance = (1/10)* Σ(xi - µ)² = (1/10)* [ (0.237 - 0.2423)² + (0.244 - 0.2423)² + (0.251 - 0.2423)² + (0.233 - 0.2423)² + (0.243 - 0.2423)² + (0.248 - 0.2423)² + (0.238 - 0.2423)² + (0.241 - 0.2423)² + (0.250 - 0.2423)² + (0.238 - 0.2423)² ]= 0.00019119
Standard deviation = √variance = √0.00019119 = 0.01383

Answer: 720

Step-by-step explanation:

Given

A club has 10 members and needs one president, a vice president, and a secretary

There are 10 positions for president i.e. 10 ways to select a member for it

Similarly, there 9 persons left to choose a position for vice president

likewise 8 persons for secretary

Total no of ways to do it are

\(\Rightarrow 10\times 9\times 8\\\Rightarrow 720\ \text{ways}\)

The correct interpretation is that the total revenue generated at a production rate of 11 units is $368. The Correct option is:

d) None of the above.

The marginal revenue function R(x) represents the additional revenue generated by producing and selling one additional unit of a product. In this case, the marginal revenue function is given by R(x) = 500 - 12x.

The notation R(11) refers to evaluating the marginal revenue function at a production rate of 11 units, which means substituting x = 11 into the function. So, we have R(11) = 500 - 12(11) = 500 - 132 = 368.

The interpretation is that at a production rate of 11 units, the total revenue generated is $368.

This means that by producing and selling 11 units of the product, the company earns $368 in revenue.

Answer:

-16 > n or n < -16

Step-by-step explanation:

First, we can write the inequality and distribute.

-6n-12 > 3(-n+12)

-6n-12 > -3n+36

Get rid of a variable first (it makes solving a lot easier). We can add 6n to both sides.

-6n-12 > -3n+36

+6n          +6n

-12 > 3n+36

Now, we can subtract 36 on both sides.

-12 > 3n+36

-36         -36

-48 > 3n

Divide by 3 on both sides.

-48 > 3n

Hope this helps!! Have a wonderful day C:

This means that there are no points on the circle\((x + 7)^2 + (y - 5)^2 = 16\)with x-coordinate 0. The circle does not intersect the y-axis.

To determine the ordinate of the equation\((x + 7)^2 + (y - 5)^2 = 16\), we need to solve for the value of y when the equation is satisfied.

The given equation represents a circle centered at the point (-7, 5) with a radius of 4 (since the radius squared is 16). The equation is in the standard form for a circle:

\((x - h)^2 + (y - k)^2 = r^2\)

where (h, k) represents the center of the circle, and r represents the radius.

In this case, the center of the circle is (-7, 5), so h = -7 and k = 5. The radius is 4.

To find the ordinate, we substitute x = 0 into the equation and solve for y:

\((0 + 7)^2 + (y - 5)^2 = 16\\7^2 + (y - 5)^2 = 16\\49 + (y - 5)^2 = 16\\(y - 5)^2 = 16 - 49(y - 5)^2 = -33\)

Since the right side of the equation is negative, there are no real solutions for y. Therefore, there is no ordinate that satisfies the equation.

a) Diminishing returns start at x = 1,  where the marginal revenue will be less than the marginal cost

b)At x = 1, the company will earn R(1) = -32 + 6 + 18 + 4 = -4,000 dollars.

c) 0 ≤ x ≤ 25 implies that the Coffee Junction company has the capacity to spend a maximum of 25,000 dollars per month on advertisements.

a) At what level of advertising spending does diminishing returns start?

Diminishing returns refers to a situation when the marginal return on investment decreases as more resources are devoted to it. For instance, in case of Coffee Junction, increasing the advertising expenditure may lead to higher revenue, but the marginal revenue (revenue generated by each additional dollar spent) will gradually decrease.

b) How much revenue will the company earn at that level of advertising spending?

At x = 1, the company will earn R(1) = -32 + 6 + 18 + 4 = -4,000 dollars.

c) What does 0≤x≤25 tell us with respect to this problem?

In this problem, 0 ≤ x ≤ 25 implies that the Coffee Junction company has the capacity to spend a maximum of 25,000 dollars per month on advertisements.

To use the Midpoint Rule with n = 4 to approximate the integral of x^2 + 5dx from 10 to 2, we first need to find the width of each subinterval.

The width is given by (b - a)/n, where a is the lower limit of integration (2), b is the upper limit of integration (10), and n is the number of subintervals (4).
Therefore, the width of each subinterval is (10 - 2)/4 = 2.
Next, we need to find the midpoint of each subinterval. The first midpoint is 2 + 1(2) = 4, the second midpoint is 4 + 1(2) = 6, the third midpoint is 6 + 1(2) = 8, and the fourth midpoint is 8 + 1(2) = 10.
Now, we can use the Midpoint Rule formula:
Δx/2 [f(x1) + f(x2) + f(x3) + f(x4)]
where Δx is the width of each subinterval and f(xi) is the function evaluated at the midpoint of the ith subinterval.
Plugging in the values, we get:
2/2 [(4^2 + 5) + (6^2 + 5) + (8^2 + 5) + (10^2 + 5)] = 80
Rounding to four decimal places, the approximate integral value is 80.0000.

The exponential equation is given as:

8^x = 64

Take the logarithm of both sides

xlog(8) = log(64)

Divide both sides by log(8)

x = log(64)/log(8)

Apply the change of base rule

Answer:

The measure of ∠CBE is 44° ⇒ a

Step-by-step explanation:

The bisector of any angle divides the angle into two congruent angles (two angles equal in measures)

∵ BE bisects ∠ABC

∴ BE divides ∠ABC into two angles, ∠ABE and ∠CBE

∵ ∠ABE ≅ ∠CBE

∴ m∠ABE = m∠CBE

∵ m∠ABE = 44°

∵ m∠ABE = m∠CBE
