Find the measure of the missing angle

a(x) = b(x) * (3x² - 10x + 21) + (8x - 8)

To divide the polynomial a(x) by b(x), we can use long division as follows:

    3x - 6

-------------------

x² + 2 | 3x² - 4x² + x

- (3x³ + 0x²)

---------------

-4x² + x

- (-4x² - 8)

-------------

8x - 8

Therefore, the quotient is 3x - 6, and the remainder is 8x - 8.

a(x) = b(x) * (3x - 6) + (8x - 8)

   -2 | 3 -4  1  0

      |    -6 20 -42

      |-------------

      | 3 -10 21 -42

The numbers on the bottom row represent the coefficients of the quotient, which are 3, -10, 21. The last number on the bottom row, -42, is the remainder. Therefore, the quotient is:

3x² - 10x + 21

8x - 8

a(x) = b(x) * (3x² - 10x + 21) + (8x - 8)

A polynomial is an expression consisting of variables and coefficients and factoring is the process of breaking down a polynomial into simpler units

A polynomial is an expression consisting of variables and coefficients, which are combined using only addition, subtraction, and multiplication. For example, 3x^2 + 2x - 1 is a polynomial, where x is the variable, 3 and 2 are coefficients, and ^2 and ^1 are exponents.

Factoring is the process of breaking down a polynomial into simpler units, which can be multiplied together to obtain the original polynomial. The simplest units are usually linear expressions, which have the form ax + b, where a and b are coefficients. For example, the polynomial 3x^2 + 2x - 1 can be factored into (3x - 1)(x + 1) by identifying two linear expressions that when multiplied together produce the original polynomial.

Factoring is an important tool in algebra, as it can help to simplify expressions, solve equations, and identify the roots of a polynomial.

Answer: To find the height of the flagpole, we can use the fact that the angles of depression and elevation are complementary angles, meaning that they add up to 90°.

Let's call the height of the flagpole "h". Then, we have:

h - 6 = h * tan(4°) (the height difference between Javier and the bottom of the flagpole)

and

h = 6 + h * tan(25°) (the height of the top of the flagpole as seen by Javier).

By substituting the first equation into the second, we can find h:

h = 6 + h * tan(25°)

h = 6 + h / tan(65°)

h * tan(65°) = 6 + h

h * tan(65°) - h = 6

h = 6 / (tan(65°) - 1)

Using a calculator, we find that h = approximately 43.3 feet. Rounding to the nearest foot, the height of the flagpole is 43 feet.

The table shows the number of pounds, x, of coffee ordered and the total price, y, in dollars, of each order. X 5 6 7 10 y $35 $42 $49 $70 Which best represents the units for the rate of change (rise over run) in the table? a.dollars. b.dollars per pound. c.pounds b.pounds per dollar

To find the units for the rate of change (rise over run), we need to determine the change in y (rise) divided by the change in x (run) for any two points in the table.

Let's choose the first and last points in the table, (5, $35) and (10, $70), respectively. The change in y is $70 - $35 = $35, and the change in x is 10 - 5 = 5. So the rate of change (rise over run) is:

rise/run = $35/5 = $7

Therefore, the best representation for the units of the rate of change is dollars per pound, as the rate of change indicates how much the price changes for every pound of coffee ordered. So the answer is (b) dollars per pound.

(a) The particular solution, y_p is 7

(b) y_p is -4x

(c) y_p is -4x + 7

(d) y_p is 8x + (7/2)

To find a particular solution to a differential equation by inspection - is to assume a trial function that looks like the non-homogeneous part of the differential equation.

(a) Given y'' + 2y = 14.

Because the no non-homogeneous part of the differential equation, 14 is a constant, our trial function will be a constant too.

Let A be our trial function:

We need our trial differential equation y''_p + 2y_p = 14

Now, we differentiate y_p = A twice, to obtain y'_p and y''_p that will be substituted into the differential equation.

y'_p = 0

y''_p = 0

Substitution into the trial differential equation, we have.

0 + 2A = 14

A = 6/2 = 7

Therefore, the particular solution, y_p = A is 7

(b) y'' + 2y = −8x

Let y_p = Ax + B

y'_p = A

y''_p = 0

0 + 2(Ax + B) = -8x

2Ax + 2B = -8x

By inspection,

2B = 0 => B = 0

2A = -8 => A = -8/2 = -4

The particular solution y_p = Ax + B

is -4x

(c) y'' + 2y = −8x + 14

Let y_p = Ax + B

y'_p = A

y''_p = 0

0 + 2(Ax + B) = -8x + 14

2Ax + 2B = -8x + 14

By inspection,

2B = 14 => B = 14/2 = 7

2A = -8 => A = -8/2 = -4

The particular solution y_p = Ax + B

is -4x + 7

(d) Find a particular solution of y'' + 2y = 16x + 7

Let y_p = Ax + B

y'_p = A

y''_p = 0

0 + 2(Ax + B) = 16x + 7

2Ax + 2B = 16x + 7

By inspection,

2B = 7 => B = 7/2

2A = 16 => A = 16/2 = 8

The particular solution y_p = Ax + B

is 8x + (7/2)

g divided by 18 equals 2; g = 36 gifts.

The correct option is (3).

The fundamental ideas in number theory, measurement, and calculation are frequently referred to as "arithmetic" (which is derived from the Greek word "arithmos," "number"). (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).

As per the given data:

A community toy drive for holidays was organized my Max.

Each family has to donate a total of 2 gifts.

Total number of families were equal to 18.

Let's assume the total number of gifts from all the families is g.

For finding the equation to find the total number of gifts given by all the families:

g = Gifts given by each family × Number of families

g = 18 × 2

∴ g divided by 18 equals 2; g = 36 gifts.

Hence, g divided by 18 equals 2; g = 36 gifts.

By the analysis of histogram , 40% percent of the cars was less than 20 years old or more than 40 years old.

The histogram may be seen here. Each column lists the age range at the bottom and the number of automobiles in that age group on the left.

The number of vehicles in the first two columns from the left (age 0-9 and 10-19) and the last two columns (age > 40) must be added together to determine the percentage of vehicles with less than 20 years or more than 40 years of age (age 40-49 and 50-59).

The total number of requested vehicles is equal to 8 that is (3 + 2 + 0 + 3).

The total number of automobiles must now be determined (by adding the cars in each column): 3 + 2 + 8 + 4 + 0 + 3 = 20

The ratio of the number of automobiles of the specified age to the total number of cars must then be calculated and converted into a percentage.

The Tracking Signal in Week 3 is -1.8.

The Tracking Signal in Week 3 can be calculated by using the following formula:

Tracking Signal = (Sum of Forecast Errors) / (Mean Absolute Deviation)

First, we need to calculate the forecast errors for each week:

Week 1 Forecast Error = Actual Demand - Forecast = 50 - 49 = 1
Week 2 Forecast Error = Actual Demand - Forecast = 54 - 56 = -2
Week 3 Forecast Error = Actual Demand - Forecast = 58 - 60 = -2

Next, we need to calculate the Mean Absolute Deviation (MAD):

MAD = (|1| + |-2| + |-2|) / 3 = (1 + 2 + 2) / 3 = 5 / 3 = 1.67

Finally, we can calculate the Tracking Signal:

Tracking Signal = (1 + -2 + -2) / 1.67 = -3 / 1.67 = -1.8

A cube is a three dimensional solid with six congruent square faces.

The expression the height and length dimensions of the rectangular prism as improper fractions, indicates that we get;

Height = (1 2/3) cm = (3 × 1 + 2)/3 cm = 5/3 cm

Length = (2 1/3) cm = (3 × 2 + 1)/3 cm = 7/3 cm

The denominators of the dimensions of the height, length and width of the rectangular prism are equivalent to 3. The edge length of the cube that can be used to fill the container should have a denominator that is a factor of 3.

The size of the cube that can be used to fill the container is therefore the cube with side length of 1/3 inches

The volume of the container = (5/3) in × (2/3) in × (7/3) in = 70/27 in³

The volume of the (1/3) inch cube = (1/3) in ×(1/3) in ×(1/3) in = 1/27 in³

The number of 1/3 inch cubes that fills the container = (70/27)/(1/27) = 70

Answer:

the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

Step-by-step explanation:

Let's denote the angles of the triangle as 3x, 4x, and 5x, where x is a constant.

Since the sum of the angles of a triangle is 180 degrees, we can write the following equation:

3x + 4x + 5x = 180

Simplifying this equation, we get:

12x = 180

Dividing both sides by 12, we get:

x = 15

Therefore, the angles of the triangle are:

3x = 3(15) = 45 degrees

4x = 4(15) = 60 degrees

5x = 5(15) = 75 degrees

So the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.
