If sinx =0.6 and AB =12, then area of triangle ABC is equal to 96 units².

As given in the question,

In triangle ABC,

AB = Perpendicular side

BC = Base

AC = Hypotenuse

sinx = 0.6

AB = 12

sinx = AB / AC

⇒0.6 = 12/AC

⇒AC = 12 /0.6

⇒ AC = 20

Using Pythagoras theorem,

AB² + BC² = AC²

⇒ BC² = 20² -12²

⇒BC = 16

Area of ΔABC = (1/2)× AB×BC

                       = (1/2)×12×16

                       = 96 units²

Therefore, if sinx =0.6 and AB =12, then area of triangle ABC is equal to 96 units².

The complete question is:

If sin x = 0.6 and AB = 12 as shown in the diagram , what is the area of ΔABC ?

Answer:

300 widgets

Step-by-step explanation:

Each time the widgets sold goes up by 100, the profits goes up by 400. This shows a ratio/slope of 4 if we were to graph this. To find out when they break even you need to subtract $400 from the first row to get to zero and the equivalent amount of widgets. If each widget is $4 then subtract 100 from 400 to get 300 widgets

well, we know the table has linear relationship, so let's use it to get the Profit function then, to get the equation of any straight line, we simply need two points off of it, so let's use those two points in the picture below.

how many will they need to sell to break-even?

well, to break-even that means no loses, no profits but no loses either, so-called breaking-even, you simply sell enough to cover costs, at that point the profit = y = 0, so

The sum of the given arithmetic series (-3)+(-6)+(-9)+. . . . . . +(-30) is  -165

The given series is:

     (-3)+(-6)+(-9)+. . . . . . +(-30)

First, we need to find how many terms in that arithmetic series.

Recall, the formula for the nth term of an arithmetic sequence is:

a(n) = a(1) + (n-1) . d

From the given series we know that:

the first term : a(1) = -3

the last term: a(n) = -30

the common difference: d = -6 - (-3) = -3

Substitute these parameters into the formula:

a(n) = a(1) + (n-1) . d

-30 = -3 + (n-1) . (-3)

-30 = -3n

n = 10

So there 10 terms in the series.

Use the sum formula:

S(n) = n/2 [a(1) + a(n)]

S(10) = 10/2 [-3 + (-30)]

S(10) = -330/2 = -165

Basically you are correct its C , ut go with your gut!

The catcher at home plate had to throw the ball 60 cm to reach the 2nd baseman at second base.

The hypotenuse of a right triangle is formed by the line from home plate to 2nd base. The triangle's two sides are each 60 feet long.

We can calculate the length of the hypotenuse using the Pythagorean theorem:

Diagonal² = side² + side²

Side= 60 feet

Diagonal = √s² + s²

Put the value in formula;

(√s² + s²)² = 60² + 60²

2s² = 2 ×60²

Further simplify;

s² = 60²

Taking root on both sides;

s = 60 feet.

Thus, the side of the square field is 60 feet.

Therefore, a catcher at home plate ought to throw the ball 60 cm to reach the 2nd baseman at second base.

Answer: x=18

Step-by-step explanation:

2x+8x=180 ==> angles CDE(8x) and ABC(2x) are opposite supplementary angles meaning that they add up to 180 degrees.

10x=180

10x/10=180/10

Answer:

9 multiple choice questions and 2 short answer questions

===========================================================

Explanation:

x = number of multiple choice

y = number of short answers

The statement "It takes about 2 minutes to answer a multiple choice question and about 6 minutes to complete a short answer question" means it takes 2x+6y minutes to answer x multiple choice and y short answer questions. We want this total to be 30 minutes or less.

Therefore, [tex]2x+6y \le 30[/tex] is one constraint.

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

Another constraint is that [tex]0 \le x \le 9[/tex] since the most multiple choice questions you can answer is 9.

Because there are 3 short answer questions, this means another constraint is [tex]0 \le y \le 3[/tex]

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

The list of constraints is:

[tex]\begin{cases}2x+6y \le 30\\0 \le x \le 9\\0 \le y \le 3\\\end{cases}[/tex]

If you were to graph and shade these regions on the xy grid, then you should get a pentagon with the following corner points

A = (0, 0)

B = (0, 3)

C = (6, 3)

D = (9, 2)

E = (9, 0)

We'll plug the coordinates of each vertex into the objective function P(x,y) = 3x+5y which will compute the number of points total after answering x multiple choice and y short answer questions. This computes the maximum points possible.

Plug in the coordinates of point A to get P(0,0) = 0

Repeat for point B to get P(0,3) = 15

Now move onto point C to get P(6,3) = 33

Then point D is P(9,2) = 37 and point E gets us P(9,0) = 27

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

Summary:

P(0,0) = 0

P(0,3) = 15

P(6,3) = 33

P(9,2) = 37

P(9,0) = 27

We see that x = 9 and y = 2 produce the largest P(x,y) value of 37

Therefore, you should answer 9 multiple choice questions and 2 short answer questions. This will yield 37 points if you were to get all of those questions correct. In other words, the most points possible are 37 when given 30 minutes.

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

Side note:

If you had unlimited time, then the most points possible are 9*3+3*5 = 27+15 = 42 which is the total number of points on the exam.

Getting a 37 out of 42 is a grade of about 37/42 = 0.881 = 88.1%

The maximum score is achieved at the corner point (9, 0), where the student answers 9 multiple-choice questions and 0 short-answer questions. The score at this point is 27, which is the maximum score the student can achieve in the given time.

To maximize the student's score in the given 30 minutes, we need to create an objective function and constraints based on the time available and the number of questions.

Let:

x = Number of multiple-choice questions to answer

y = Number of short-answer questions to answer

Objective Function (Score):

The score can be calculated as the sum of points obtained from multiple-choice questions and short-answer questions:

Score (S) = 3x (for multiple-choice questions) + 5y (for short-answer questions)

Constraints:

1. Time Constraint: The total time taken to answer all the questions should not exceed 30 minutes:

Time for multiple-choice questions + Time for short-answer questions ≤ 30

2. Number of Questions Constraint: The student can't answer more questions than available:

Number of multiple-choice questions (x) ≤ 9 (total number of multiple-choice questions available)

Number of short-answer questions (y) ≤ 3 (total number of short-answer questions available)

Now, let's consider the time taken to answer each type of question:

- Time for multiple-choice questions: 2 minutes per question

- Time for short-answer questions: 6 minutes per question

Based on the above information, the time constraint can be written as an equation: 2x + 6y ≤ 30

Now, we need to maximize the score (S) by selecting the values of x and y that satisfy the above constraints. This is a linear programming problem that can be solved using various optimization techniques, such as the graphical method, simplex method, or linear programming software.

Since this is a simple problem with a small number of variables and constraints, we can use the graphical method to find the maximum score. We will graph the feasible region defined by the constraints and find the corner points of the feasible region. Then, we will calculate the score (S) at each corner point and select the one with the highest score.

The feasible region will be bounded by the lines:

2x + 6y ≤ 30 (Time constraint)

x ≤ 9 (Number of multiple-choice questions constraint)

y ≤ 3 (Number of short-answer questions constraint)

The corner points of the feasible region are the intersection points of these lines.

Now, calculate the score (S) at each corner point:

For (0, 0): S = 3(0) + 5(0) = 0

For (0, 3): S = 3(0) + 5(3) = 15

For (9, 0): S = 3(9) + 5(0) = 27

The maximum score is achieved at the corner point (9, 0), where the student answers 9 multiple-choice questions and 0 short-answer questions. The score at this point is 27, which is the maximum score the student can achieve in the given time.

Answer: |t - 15| ≤ 30 ; -30 ≤ t - 15 ≤ 30

Step-by-step explanation:

To set up the equation, we have to find the center, and the tolerance, so that we can use formula "|x - c| ≤ t"

First, we can find the tolerance by adding both number, then dividing by 2 --> -15 + 45 = 30 --> 30/2 = 15, so we now know that the center is 15

Next, we can find the tolerance by finding the distance between the center and one of the number --> 15 - (-15) = 30, so we now know that the tolerance is 30

Now we can set up our equation,

center (c) = 15

tolerance (t) = 30

|t - 15| ≤ 30

Now that we have our equation, we can set up the inequality

|x - c| ≤ t = -t ≤ x - c ≤ t

so,

-30 ≤ t - 15 ≤ 30

The triangle with vertices J(5 , 0), K(5 , -8), and L(0 , 0) has its circumcenter located at Point (5/2 , -4).

Circumcenter of a triangle refers to the point inside a triangle at which the perpendicular bisectors of the sides of a triangle intersect. This point is also equidistant from the three vertices.

Given the location of the three vertices, there are different methods that can be used to locate the circumcenter of the triangle.

One method is to calculate the intersection point of any two perpendicular bisectors.

First is to find the midpoint of the two sides given the formula:

midpoint = M(xm ,ym) = [(x1 + x2)/2 , (y1 + y2)/2]

Consider side JK and side KL.

JK : midpoint = [(5 + 5)/2 , (0 + -8)/2] = (5 , -4)

KL : midpoint = [(5 + 0)/2 , (-8 + 0)/2] = (5/2 , -4)

Next, solve for the slope of each side and slope of its perpendicular bisector (-1/m).

m = (y2 - y1)/(x2 - x1)

JK : m = (-8 - 0)/(5 - 5) = -8/0 = 0/8 = 0

KL : m = (0 - -8)/(0 - 5) = 8/-5 = 5/8

Using the midpoint and the slope of the perpendicular bisector, set up its equation using the point-slope form.

(y - ym) = -1/m(x - xm)

JK : (y - -4) = 0(x - 5)

y + 4 = 0

y = -4

KL : (y - -4) = 5/8(x - 5/2)

y + 4 = 5/8 x - 25/16

y = 5/8 x - 89/16

Find the intersection (circumcenter of the triangle) of these two perpendicular bisectors.

Since from the equation 1, y = -4, input this value to the 2nd equation.

y = 5/8 x - 89/16

-4 = 5/8 x - 89/16

5/8 x = 25/16

x = 5/2

y = -4

Hence, the circumcenter is at Point (5/2 , -4).
