To write a division expression from a fraction, identify the numerator, which is the dividend, while the denominator is the divisor.

A division expression is an algebraic expression using the division operand (÷).

Algebraic expressions involve the combination of numbers, constants, values, and variables with mathematical operands.

The result of a division operation, which is one of the four basic mathematical operations, is known as the quotient.

Thus, we can conclude that the dividend is related to the numerator of the fraction just as the divisor is related to the denominator of the fraction.

Well the half point of 427 and 428 is 427.5 so 427.5.

the area of the dartboard is approximately 254.34 square inches.

The area of a dartboard can be calculated using the formula for the area of a circle, which is given by:

Area = π * \(radius^2\)

Given that the radius of the dartboard is 9 inches, we can substitute this value into the formula:

Area = π * \(9^2\)

Area = π * 81

To calculate the area, we need to use the value of π (pi). Pi is an irrational number and is commonly approximated as 3.14. Using this approximation, we can calculate the area:

Area ≈ 3.14 * 81

Area ≈ 254.34 square inches

Let's trace the code step by step:x=1:

Here, we are initializing the value of x as 1.

if (x>3):

As x is 1 which is less than 3, the code will skip the if statement.

Thus, the control flow will be shifted to the else block.

z=x-2:

As the control flow is in the else block, it will execute this statement.

Here, the value of x is 1.

Therefore, z=x-2 will become z=1-2, which is equal to -1. z will hold the value -1.end:

Here, the else block will come to an end.

z=0:

As the last value of z was -1, it will be updated with the new value 0.x=2:

The value of x will be updated with 2.

Therefore, x will hold the value 2 now.

z=3:

As the value of x is 2, z will hold the value 2-2=0. Then, z will be updated with 3.

The answer is B, 1/9.

To determine the result of the integral ∫(1 to ∞) x^2/(x^3+2)^2 dx, we can use the comparison test for improper integrals:

First, observe that x^2/(x^3+2)^2 < x^2/x^6 = 1/x^4 for x > 1, since the denominator in the original integrand is larger than x^6.

Now, consider the integral of 1/x^4 from 1 to ∞:

∫(1 to ∞) 1/x^4 dx = [(-1/3)x^(-3)](1 to ∞) = (-1/3)(0 - 1/3) = 1/9

Since 0 < x^2/(x^3+2)^2 < 1/x^4 for x > 1 and the integral ∫(1 to ∞) 1/x^4 dx converges, the given integral ∫(1 to ∞) x^2/(x^3+2)^2 dx also converges by the comparison test.

Hence, the answer is B, 1/9.

The candy store will use 103 grams of sugar in 10 hours.

To find out how many grams of sugar the store will use in 10 hours, we can simply multiply the amount of sugar used in one hour (10.3 grams) by the number of hours (10).

To solve the problem, we use a simple multiplication formula: the amount used per hour (10.3 grams) multiplied by the number of hours (10) to find the total amount of sugar used in 10 hours.

We can interpret this problem using a rate equation: the rate of sugar usage is 10.3 grams/hour, and the time period is 10 hours. Multiplying the rate by the time gives the total amount of sugar used.

So the calculation would be:

10.3 grams/hour x 10 hours = 103 grams

Therefore, the candy store will use 103 grams of sugar in 10 hours.

The rate at which the distance from the plane to the station is increasing when it has a total distance of 4 miles away from the station is 317.5 mi/h.

A rate in which a certain number of units of the first quantity are compared to one unit of the second quantity is not the same as a unit rate. In other words, we may state that the comparison's second amount is always 1.

Thus, P denotes the plane's location, R denotes the radar's location, and V denotes the point that is vertical to the radar and at the plane's height.

Assume that h is the height of the plane, s is the separation from the radar, and x is the separation from point V.

The plane travels at 480 miles per hour and has a 3 mile height. Ds-480 miles per hour.

dt By Pythagorean theorem,

x² = h² + s²

x² = 3²+s²

x² = 9 + s²

Differentiate implicitly with respect to t.

2x dx/dt = 2s ds/dt + 0

x dx/dt = s ds/dt

Use (1)

dx/dt = \(\frac{dx}{dt} =\frac{\sqrt{x^2-9} }{x}\)

= √7/4 x 480

= 120√7

Answer:

x² + 12x + 36  

Step-by-step explanation:

Given the quadratic expression, x² + 12x + ___,  with a missing constant value, c:

We can find the value of the constant by taking the coefficient of the middle term, dividing it by 2, and squaring its quotient.  In other words, \((\frac{b}{2})^{2}\).  In the given quadratic expression, b = 12.  Substitute the value of b = 12 into \((\frac{b}{2})^{2}\), to find the value of the constant.

x² + 12x + \((\frac{b}{2})^{2}\)

x² + 12x + \((\frac{12}{2})^{2}\)

x² + 12x + (6)²

x² + 12x + 36  ⇒ This is the perfect square trinomial.

Therefore, the missing value for the constant, c, is 36, making the quadratic equation a perfect square trinomial, x² + 12x + 36.

The vector function, r(t) that represents the curve of intersection of the two surfaces, the paraboloid and the parabolic cylinder is given by < t, 3t2, 8t2 + 9t4 >. It is attained by applying the concept of vectors to the assigned problem.

What is a vector?

A vector is any quantity that contains both magnitudes as well as direction. Geometrically, one can imagine a vector as a directed line segment, whose length denotes the magnitude of the vector and the direction is shown by the arrow, which is generally taken from its tail to its head. Using an arrow with a line specifies that it is not only scalar but also has some direction.

Calculation of the vector function representing the curve of intersection of the paraboloid and parabolic cylinder

A vector function r(t) is represented as: r(t) = < x, y, z >

Given: y = 3x2                         – 1

z = 8x2 + y2                             – 2

Let,

x = t

Using x = t in equations 1 and 2

y = 3t2

z = 8t2 + y2

Putting the value of y in z, we get,

z = 8t2 + (3t2)2

z = 8t2 + 9t4

Substitute  these values of x, y, and z in vector representation to obtain the result, i.e. < t, 3t2, 8t2 + 9t4 >

Hence, the value of vector function r(t) is: < t, 3t2, 8t2 + 9t4 >

The approximate probability that between 70 and 90 is 0.728.

Using normal distribution,

Mean = xbar = np = 400 × 0.2 = 80

Standard deviation = √[np(1-p)] = √(80 × 0.8) = 8

To ensure that the distribution is normal,

np ≥ 10

80 ≥ 10

And,

np(1-p) ≥ 10

80(0.8) = 320 ≥ 10

Hence, we use the z-tables for this

a) Convert 75 and 100 into standardized scores.

A value's standardized score is equal to the value minus the mean divided by the standard deviation.

z = (x - xbar) ÷ σ

For 75

z = (75 - 80) ÷ 8 = - 0.625

For 100

z = (100 - 80) ÷ 8 = 2.5

To calculate the approximate likelihood that between 75 and 100 (inclusive) mufflers will be replaced under warranty.

P(75 ≤ x ≤ 100) = P(-0.625 ≤ z ≤ 2.5)

For these probabilities, use data from the normal probability table.
