What is the area of a sector when theta=pi/12 radians and r =4

Answer:

f(2) = 22

Step-by-step explanation:

To find f(#), plug the number into each x of the equation.

f(x) = 10x + 2

f(2) = 10(2) + 2

Simplify the parentheses by multiplying.

f(2) = 20 + 2

Add.

f(2) = 22

The cost of 900 shares would by $51,862 if the cost of each share is 57 5/8.

According to the given question.

The cost of each share is $57 5/8 or $461/8.

Therefore,

900 share would cost

= 900 × $461/8

= 900 × $57.625

=  $51,862

Hence, the cost of 900 shares would by $51,862 if the cost of each share is 57 5/8.

The solution is Option B.

The system of equations is solved and the value of x and y is ( 3 , 7 )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be represented as A

Now , the value of A is

-2x + 3y = 15   be equation (1)

Let the first equation be represented as B

Now , the value of B is

x + y = 10   be equation (2)

On simplifying the equation , we get

Subtracting y on both sides of the equation , we get

x = 10 - y   be equation (3)

Substituting the value of x from equation (3) in equation (2) , we get

-2 ( 10 - y ) + 3y = 15

On simplifying the equation , we get

-20 + 2y + 3y = 15

Adding 20 on both sides of the equation , we get

5y = 35

Divide by 5 on both sides of the equation , we get

y = 7

Substitute the value of y in equation (3) , we get

x = 10 - 7

x = 3

Hence , the value of x and y is 3 and 7 respectively

The required total area bounded by the curves y = x and \(y = x^3/9\)  is 3.6 square units.

To find the total area bounded by the curves \(y = x\)  and \(y = x^3/9\), we need to determine the points of intersection between the two curves. We can then integrate the difference between the curves over the interval between these points.

Setting y = x and y = x^3/9 equal to each other, we have:

\(x = x^3/9\\x^3 - 9x = 0\)

\(x(x^2 - 9) = 0\)

This equation is satisfied when x = 0 or \(x^2 - 9 = 0\).

For this \(x^2 - 9 = 0\), we have two solutions:

\((x - 3)(x + 3) = 0\)

This gives x = 3 and x = -3 as the other two points of intersection.

To find the total area, we integrate the difference between the two curves over the interval [-3, 3]:

\(Area = \int_{-3}^3 (x - x^3/9) dx\)

Evaluating this integral:

\(= [9x^3/27 - x^5/45]_{-3}^3\\= [(3^3 - (-3)^3)/3 - (3^5 - (-3)^5)/45]\\= [54/3 - 648/45]\\= [18 - 14.4]\\= 3.6\)

Therefore, the total area bounded by the curves \(y = x\) and \(y = x^3/9\)  is 3.6 square units.

The area of sector LMN is approximately 11.47 square units.

To find the area of a sector, we need to use the formula A = (θ/360)πr², where A is the area, θ is the central angle in degrees, and r is the radius of the circle.

In this case, the central angle is given as 84 degrees, and the radius is not explicitly given. However, we can find the radius by using the fact that the length of the arc is equal to the circumference of the circle multiplied by the ratio of the central angle to 360 degrees. The length of the arc can be found using the formula L = 2πr(θ/360).

Since the length of the arc is equal to the length of LM, which is 18 units, we can set up the equation as follows: 18 = 2πr(84/360).

Simplifying the equation, we have 9 = πr(84/360). Dividing both sides by π(84/360), we get r ≈ 9/(π(84/360)).

Now that we have the radius, we can substitute it into the formula for the area of a sector. The area is A ≈ (84/360)π(9/(π(84/360)))².

Simplifying further, A ≈ (84/360)(9/(π(84/360)))².

Calculating this expression, we find that A ≈ 11.47 square units (rounded to the nearest hundredth).

Therefore, the area of sector LMN is approximately 11.47 square units.

The value of log7 base 10 is 0.84509804.The logarithm of a number is the exponent to which another fixed number (in this case 10) must be raised to produce that number.

The logarithm of a number is the exponent to which another fixed number (in this case 10) must be raised to produce that number. So to find the logarithm of 7 base 10, we must find the exponent to which 10 must be raised to produce 7. This can be solved using a calculator by taking the logarithm of 7 (log 7) and setting the base to 10 (log 10). The answer is 0.84509804. This means that 10 must be raised to the power of 0.84509804 to produce 7.

To factor the quadratic expression 3x^2 - x - 2, we need to find two binomials that, when multiplied, give us the original expression.

The factored form of the quadratic expression can be determined by breaking down the middle term (-x) into two terms whose coefficients multiply to give the product of the coefficient of the squared term (3) and the constant term (-2). In this case, the product is -6. We are looking for two numbers whose sum is equal to -1 (the coefficient of the middle term) and whose product is equal to -6.

The numbers that satisfy these conditions are -3 and 2. We can now rewrite the expression using these numbers:

3x^2 - x - 2 = 3x^2 - 3x + 2x - 2

Next, we group the terms and factor by grouping:

(3x^2 - 3x) + (2x - 2) = 3x(x - 1) + 2(x - 1)

Now, we can see that we have a common binomial factor of (x - 1) in both terms. We can factor this out:

3x(x - 1) + 2(x - 1) = (3x + 2)(x - 1)

Therefore, the factored form of the quadratic expression 3x^2 - x - 2 is (3x + 2)(x - 1).

The area of the rectangular parking lot is 929.03 square meters.

Use the formula for the area of a rectangle to calculate the area of the rectangular parking lot, which is given as:

Area = length × width

We know that the parking lot is 67.5 ft wide and 148 ft long, the area can be calculated as follows:

Area = 67.5 ft × 148 f

t= 9990 sq. ft

However, the question asks for the area in square meters, so we need to convert square feet to square meters. 1 square foot is equal to 0.092903 square meters, so we can use this conversion factor to convert square feet to square meters.

Area in square meters = Area in square feet × 0.092903

= 9990 sq. ft × 0.092903

= 929.03 sq meters

Therefore, the area is 929.03 square meters.

Answer: 412.5 ml

Step-by-step explanation:

500 ( 1 - 25%) ( 1 + 10%)

= 412.5 ml

Answer:

412.5 ml

Step-by-step explanation:

To decrease 500 ml by 25%, you would need to multiply 500 by 0.25 to find the amount of decrease:

Subtract that amount from the original value:

Therefore decreasing 500 ml by 25% would give us 375 ml.

To then increase this value by 10%, you would multiply it by 0.10 to find the amount of increase:

Now, add that amount to the previous value:

Therefore, if you decrease 500 ml by 25% and then increase it by 10%, the final result is 412.5 ml.

if the number of times you take the test were independent variable of the chance you fail what could that mean the difficulty of the test is consistent and unchanging.

The difficulty of the test is consistent and unchanging, making it so that the chance of failing is solely determined by the individual's performance on the test. Factors such as knowledge of the subject and the ability to focus can play a role in a person's success, but the actual chance of failing is not affected by how many times the test is taken. This means that those who fail the test will have to work harder and prepare better in order to pass it on the next attempt. Taking the test multiple times does not guarantee a higher chance of success, as the difficulty remains the same each time due to independent variable.
