Utilizing differentiation, the biggest value of y=0 in the system's solution set.

One of the two fundamental concepts of calculus is differentiation. Differentiation is a method for finding a function's derivative. Differentiation is a mathematical technique used to calculate the instantaneous rate of change of a function based on one of its variables. Velocity, or how quickly a distance varies in respect to time, is the most common example. Differentiation's opposite is finding an antiderivative.

Differentiating the 1st equation, we get

x=5.5

Putting back in the equation.

y = -5.75

and differentiating the 2nd equation, we get

x=3

Putting back in the equation

y= 0

From the given image, we have that:

1. The distance from A to B is of 6 units.

2. The lengths are given as follows:

3. The length of segment AD is of 5 units.

When two points have one equal coordinate, as is the case in this problem for AB, CD and BC, the distance is given by the subtraction of the different coordinate.

Hence, considering the coordinates of the vertices on the given image, the distances are given as follows:

The perimeter of a polygon is the sum of the lengths of all the outer sides of the polygon, hence:

P = AB + CD + BC + AD.

The perimeter in this problem is of 18 units, hence the length of AD is given as follows:

The player is expected to win $54.75

Explanation:

Here, we want to get the fair prize of the game

From the question, there are 4 prizes

When reaching into the box, we can only pick 1

Assuming that each of the prizes have the same probability oof being picked, the probability of picking any of the prize is 1/4

We have to multiply the probability by each of the price tag, then sum

Mathematical expressions that include multiplication are called multiplication expressions. We combine the integers and then the like variables to simplify the equation. We will therefore obtain x to the second power if we multiply two xs together.

An answer to a multiplication sentence is obtained by multiplying the various components. The multiplier (first number), multiplicand (second number), and product are the components of a multiplication phrase (third number).

Answer:

(3y + 11)° = 50°

10y° = 130°

(4x - 22)° = 50°

(7x + 4)° = 130°

Explanation:

First, find the value of the variable. Let's find y.

(3y + 11) + 10y = 180 (sum of adjacent angles on a straight line)

Simplify and solve the equation.

13y + 11 = 180

13y = 169

y = 13

Substitute y into the angle measures to find values.

3(13) + 11 = 50

10(13) = 130

Hence, (3y + 11)° = 50° and 10y° = 130°.

Next, find x.

(7x + 4) + (4x - 22) = 180 (sum of adjacent angles on a straight line)

Simplify and solve the equation.

11x - 18 = 180

11x = 198

x = 18

Substitute x into the angle measures to find values.

4(18) - 22 = 50

7(18) + 4 = 130

Hence, (4x - 22)° = 50° and (7x + 4)° = 130°.

Alternatively, you do not have to find x to find (4x - 22)° and (7x + 4)°.

4x - 22 = 3y + 11 = 50° (vertically opposite angles)

7x + 4 = 10y = 130° (vertically opposite angles)

On the other hand, the slope m is given by the following equation:

where (X1,Y1) and (X2,Y2) are points on the line. In this case, we can take the points:

Answer:

150 is the number

Step-by-step explanation:

The equation we should set up is from the sentence "14% of what number is 21"
To rearrange it into a proper equation, replace "of what number" with " * x "
and "is" with "="
The sentence becomes:

14% * x = 21

since 14% = 0.14, replace 14% with 0.14 in the equation

0.14 * x = 21

divide both sides by 0.14

x = 21 / 0.14

x =  150

then 3 choices for the second (M, T, and H; say we choose H), then 2 choices for the next

letter (M and T; say we choose M) and only one choice at the last stage (T). Thus, there are

4 · 3 · 2 · 1 = 24 ways to spell a code word with the letters MATH.
