We are asked to determine the value of the variation of the angle with respect to "x". To do that we will determine an equation that relates "x" and the angle using the following right triangle:

We can use the function tangent since this is defined as:

Now, we plug in the values:

Now, we will determine the angle when "x = 2000". We substitute 2000 in the equation:

Now, we take the inverse function of the tangent:

Solving the operations we get:

Therefore, the angle is 56.31 degrees or 0.983 radians.

We are asked to determine the value of the derivative of "x" with respect to "t". Since this is equivalent to the velocity of the plane we have that:

Now, we are asked to determine the derivative of the angle with respect to time. To do that we will determine the derivative with respect to time on both sides of the equation:

For the derivative on the left side, we know that the derivative of the tangent is the secant squared, therefore, we have:

Now, we determine the derivative on the right side using the following formula:

Applying the rule we get:

Now, we solve for the derivative of the angle with respect to time:

Now, we substitute the values:

Solving the operations:

Therefore, the variation of the angle with respect to time is 0.047 rad/s.

This means that the dish is rotating at a speed of 0.047 rad/s.

Answer Letter A

     The number that produces zero when multiplied by an is known as the additive inverse of a number, or a, in mathematics. The opposite (number),[1] sign change,[2] and negation are other names for this number. [3] The additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive, when applied to a real number. The additive inverse of zero is zero.

   Subtraction, which can be seen as adding the opposite, is closely related to additive inverse:

   a − b  =  a + (−b).

On the other hand, additive inverse can be compared as subtracting from zero:

−a = 0 − a.

As a result, the unary minus sign can be used to represent subtraction without using the "0" symbol, even though there shouldn't be a space after the unary "-" in proper typography.

 Negation has the following algebraic characteristics in addition to the identities mentioned above:

It is an Involution operation when (a) = a.

−(a + b) = (−a) + (−b)

−(a − b) = b − a

a − (−b) = a + b \s(−a) × b = a × (−b) = −(a × b)

(−a) × (−b) = a × b

Particularly, (a)2 = a2.

On 300 call the station first give away all three prizes to one caller.

The smallest positive integer that is divisible by both a and b is known as the least common multiple (lcm), lowest common multiple (lcm), or smallest common multiple of two numbers a and b in mathematics and number theory. The LCM method is used to determine the least multiple of two or more numbers. Least Common Multiple is referred to as LCM. The LCM of two numbers can be divided by both of them. The LCM of 6 and 8 is 24, for instance. 24 can be divided by both 6 and 8.

In Mathematics, a function simply refers to a mathematical expression which is typically used for defining and representing the relationship that exists between two or more variables such as an ordered pair.

This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable (Set A) to an output variable (Set B).

The combination of two shirts and six hats will maximize the amount of money the shopper can spend.

An inequality results from the comparison of two or more algebraic expressions using the symbols <, > ≤, or ≥. They are mathematical expressions with unequal sides.

Let's assume x is the number of shirts and y is the number of hats brought then,

Total amount spend = 21x + 16y

It is given that the total amount the shopper can spend is $140.

So, 21x + 16y ≤ 140,

As x and y are the number of shirts and the number of hats so x and y will assume positive integral values only, to find out the values of x and y plot the region 21x + 16y ≤ 140 with x ≥ 0, y ≥ 0 as shown in the graph.

From the graph, it is clear that the highest integer value which is close to the boundary of 21x + 16y ≤ 140 is x = 2 and y = 6.

The amount spend when x = 2 and y = 6 is 21(2) + 16(6) = 138

Hence, two shirts and six hats will maximize the amount of money the shopper can spend.

Two figures are said to be "congruent" if they can be positioned perfectly over one another. Both of the bread slices are the same size and shape when stacked one on top of the other. Congruent refers to things that are exactly the same size and shape.

For these items, the word equal is frequently used in place of congruent. If two line segments are the same length, they are said to be congruent. If two angles have the same measure, they are said to be congruent. If two circles have the same diameter, they are congruent.

While equality deals with numbers, congruence deals with shapes (also known as objects). Neither "two shapes are equal" nor "two numbers are congruent" are statements that you make. If one shape can be perfectly superimposed on the other, then two shapes are said to be congruent. While equality deals with numbers, congruence deals with shapes (also known as objects).

The monthly deposit that Florence must make in order to reach her goal is  $366.74.

The series of payments that must be made is known as an annuity. An annuity is a series of payment made over a period of time. The amount that is invested monthly would grow at an exponential rate. This is because both the amount invested and the interest that has been accrued grows at each compounding period.

The formula to determine the monthly deposit is:

Monthly deposit = future value / annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

(65 - 22) x 12

43 x 12 = 516

Answer:

  no universal test point

Step-by-step explanation:

You want to know if there is or is not a universal test point that can be used for testing the shading for a linear inequality.

The purpose of a test point for the graph of an inequality is to determine whether the shaded area includes the test point or not. A single inequality will divide the universal set into two parts: one part that is the solution set, and one part that is not the solution set.

A point that is well inside the solution set (or not-a-solution set) will tell you which side of the boundary is shaded. Any point that always meets that requirement could be considered a universal test point.

The boundary point(s) between these sets may or may not be shaded, but its(their) shading, or lack of it, will not tell you which half of the universal set is the solution set. That is, any point that falls on the boundary of the solution set is not a suitable test point.

The boundary can be anywhere, so there is no single universal test point.

__

Additional comment

A set of three non-collinear points can be considered to be a universal test set. Together, they can tell you which part of the universal set is the solution set. At most, the boundary line can pass through two of them, so the third can tell you which half of the universe it lies in.

step 1

Find out the x-intercept (value of x when the value of y=0)

For h(x)=0

substitute

It is given in the question that at the clothing store T-shirts are on sale, 3 for $10. A customer at the store says that one T-shirt should cost $7 at this rate.

We have to find the error made by the customer while calculating the rate of a T- shirt.

To find the rate of a shirt we will divide the number of shirts by the total amount.

Hence, the rate of a shirt will be $  10/3
