Explanation:

On the unit circle we have some point (x,y) such that x = cos(theta) and y = sin(theta). The sine corresponds to the y coordinate of the point on the circle. Quadrant IV is below the x axis which explains why sine is negative here, since y < 0 here.

Since sine is negative, so is cosecant as this is the reciprocal of sine

csc = 1/sin

In quadrant IV, cosine is positive as x > 0 here. So the ratio tan = sin/cos is going to be negative. We have a negative over a positive when we divide.

Because tangent is negative, so is cotangent.

The only positive functions in Q4 are cosine and secant, which is because sec = 1/cos.

Quadrant is the region enclosed by the intersection of the X-axis and the Y-axis.

Trigonometric functions  sine , tangent , cotangent ,  and cosecant are negative in fourth quadrant.

In first quadrant, all trigonometric function will be positive.

In second quadrant, only sine and cosecant trigonometric function is positive.

In third quadrant, only tangent and cotangent will be positive.

In fourth quadrant, only cosine and secant will be positive . Therefore,  Trigonometric functions  sine , tangent , cotangent ,  and cosecant are negative in fourth quadrant.

Answer:

57 3/11 square units

Step-by-step explanation:

The area of a parallelogram is the product of its height and the length of the perpendicular base. The given conditions allow us to find the area two ways. Of course, the area is the same in each case, so ...

area(KLMN) = KN·LP = KL·MQ

KN·5 = KL·6 . . . . . substituting the given numbers

KL = (5/6)·KN . . . . solve for one of the lengths in terms of the other

Now, the perimeter is the sum of the side lengths, and opposite sides are the same length, so we have the relation ...

perimeter(KLMN) = KN + KL + KN + KL = 2(KN +KL)

42 = 2(KN +(5/6)KN) = (11/3)KN . . . . . substitute for KL from above

KN = 42·(3/11) . . . . . . multiply by 3/11

area(KLMN) = KN·5 = (42·3/11)·5 = 630/11 = 57 3/11

Check

KN = 126/11

KL = 5/6·KN = 105/11

KN·5 = 630/11 = KL·6 = 630/11 . . . . . areas match

KL+KN = 231/11 = 21 = half the perimeter . . . . . perimeter agrees

Recall that you have to write complete question in order to get good and precise answers. I found a similar question and attached the options below. However, the question has missing graph, too. So let's face this problem in a general way.

1. It must be proportional because the points lie on the same line.

The points not not only must lie on the same line, but that line must pass through the origin because two quantities x and y are directly proportional if we can write an expression:

[tex]y=kx \\ \\ Being \ k \ the \ constant \ of \ proportionality[/tex]

That is, if x increases, y also increases at the same rate.

2. It must be proportional because each time x increases by 2, y stays the same.

In this case as x increases by 2, y stays the same, meaning that this relationship is constant. So in this case they aren't proportional, but we can write:

[tex]y=c \\ \\ Being \ a \ real \ constant[/tex]

3. It cannot be proportional because the y-values are not whole numbers:

This doesn't make sense. The only condition for a direct proportion is that the line must pass through the origin and for any constant of proportionality [tex]k[/tex]

4. It cannot be proportional because a straight line through the points does not go through the origin:

This is is true because the definition of direct proportion is that the line passes through the origin for some constant k:

[tex]y=kx[/tex]

So if I could see the graph, I'd choose the fourth option.

Answer:

8 more glasses

Step-by-step explanation:

12-4=8

Final answer:

After serving 4 glasses of the original 12 glasses of lemonade, Jasmine can serve 8 more glasses. We calculate this by subtracting the number of glasses already served from the total number of glasses the pitcher contains.

Explanation:

Jasmine made a pitcher of lemonade that contains 12 glasses. After she serves 4 glasses of lemonade, we can calculate how many more glasses, g, she can serve by subtracting the number of glasses served from the total number of glasses that the pitcher initially had. The equation then becomes: 12 glasses - 4 glasses = g.

To find the value of g, we subtract 4 from 12, which gives us:

g = 12 - 4 = 8

Therefore, Jasmine can serve 8 more glasses of lemonade from the pitcher.

Answer:

[tex]A= (-1,0)\\B=(1,0)[/tex]

Step-by-step explanation:

The transformation of the segment AB is:

[tex](x+4,\ y-3)[/tex]

Given the points of the line segment A'B':

[tex]A'=(3,-3)[/tex] and  [tex]B'=(5,-3)[/tex]

The coordinates of the points A and B in the line segment AB,can be calculated through this procedure:

For A:

x-coordinate:

Substitute the x-coordinate of A' (we can represent it with[tex]x_{(A')}[/tex]) into [tex]x_{(A')}=x_A+4[/tex] and solve for [tex]x_{A}[/tex], which is the x-coordinate of A:

[tex]x_{(A')}=x_A+4\\\\3=x_A+4\\\\3-4=x_A\\\\x_A=-1[/tex]

y-coordinate:

Substitute the y-coordinate of A' (we can represent it with[tex]y_{(A')}[/tex]) into [tex]y_{(A')}=y_A-3[/tex] and solve for [tex]y_{A}[/tex], which is the y-coordinate of A:

[tex]y_{(A')}=y_A-3\\\\-3=y_A-3\\\\-3+3=y_A\\\\y_A=0[/tex]

The point of A is: (-1,0)

For B:

x-coordinate:

Substitute the x-coordinate of B' (we can represent it with[tex]x_{(B')}[/tex]) into [tex]x_{(B')}=x_B+4[/tex] and solve for [tex]x_{B}[/tex], which is the x-coordinate of B:

[tex]x_{(B')}=x_B+4\\\\5=x_B+4\\\\5-4=x_B\\\\x_B=1[/tex]

y-coordinate:

Substitute the y-coordinate of B' (we can represent it with[tex]y_{(B')}[/tex]) into [tex]y_{(B')}=y_B-3[/tex] and solve for [tex]y_{B}[/tex], which is the y-coordinate of B:

[tex]y_{(B')}=y_B-3\\\\-3=y_B-3\\\\-3+3=y_B\\\\y_B=0[/tex]

The point of B is: (1,0)

The original coordinates of points A and B on the line segment AB, before the transformation, are (-1, 0) and (1, 0), respectively, as found by applying the inverse of the transformation to the coordinates of A' and B'.

To find the original coordinates of the line segment AB before the transformation, we need to apply the inverse of the given transformation to the new coordinates of A' and B'. The transformation is given by (x, y) → (x+4, y-3), so the inverse would be (x', y') → (x'-4, y'+3).

For point A' with coordinates (3, -3), applying the inverse transformation gives us:
A = (3-4, -3+3) = (-1, 0)

For point B' with coordinates (5, -3), applying the inverse transformation gives us:
B = (5-4, -3+3) = (1, 0)

Therefore, the original coordinates of points A and B on the line segment AB are (-1, 0) and (1, 0), respectively.

Answer:

Final answer is slope [tex]m=\frac{5}{2}[/tex]

Step-by-step explanation:

Given equation is [tex]5x-2y=7[/tex]

Now question says to find the slope.

Since given equation [tex]5x-2y=7[/tex] is a linear equation so we need to compare [tex]5x-2y=7[/tex] with slope intercept formula [tex]y=mx+b[/tex] to get the value of slope m.

Since [tex]5x-2y=7[/tex] is not in that form so first let's rewrite it in y=mx+b form

[tex]5x-2y=7[/tex]

[tex]-2y=-5x+7[/tex]

[tex]y=\frac{-5x+7}{-2}[/tex]

[tex]y=\frac{5}{2}x-\frac{7}{2}[/tex]

Now comparing with y=mx+b, we get [tex]m=\frac{5}{2}[/tex]

Hence final answer is slope [tex]m=\frac{5}{2}[/tex]

Answer:

Slope = 5/2

Step-by-step explanation:

It is given an equation of line  5x – 2y = 7

To find the slope of equation we have to rewrite this equation in y = mx + c form

To convert the given equation to y = mx + c

The given equation is

 5x – 2y = 7

⇒ 5x + 7 = 2y

⇒ 2y = 5x + 7

⇒ y = (5x + 7)/2

y = 5x/2 + 7/2

The above equation is of the form y = mx + c

Here slope = m = 5/2

Step-by-step explanation:

Final answer:

To calculate the radius of the cylindrical can, we use the volume of a cylinder formula, V = πr²h. After substituting the given values and solving for r, the radius of the can is found to be approximately 5.64 cm.

Explanation:

To find the radius of the cylindrical can that contains 1500 cm³ of coconut milk with a height of 15 cm, we can use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height.

Given V = 1500 cm³ and h = 15 cm, we can rearrange the formula to solve for r (radius).

The rearranged formula is r = √(V/(πh))

Plug the values into the formula:

r = √(1500 cm³/(3.142 × 15 cm))

r = √(1500/47.13)

r = √(31.83)

r ≈ 5.64 cm

Therefore, the radius of the can is approximately 5.64 cm.

Answer:

rate of flow of hot water = 480 L/hour

and rate of flow of cold water = 720 L/hour

Step-by-step explanation:

Suppose rate of flow of hot water = x

and rate of flow of cold water = y

Given that,

Twice the water flow in the hot water pipe is equal to three times the water flow from the cold pipe.

Combined it equals 1200 L/hour.

According to the question

2x = 3y

x + y = 1200

x = 1200 - y

put this value of x in equation1

2(1200-y) = 3y

2400 - 2y = 3y

2400 = 5y

y = 480

x = 3(480)/2

x = 720

The flow rate in the hot water pipe is 720 L/hour, and the flow rate in the cold water pipe is 480 L/hour, solved through a system of linear equations.

The student's question involves solving a system of linear equations to find the flow rate in each pipe. The problem states that twice the flow in the hot water pipe is equal to three times the flow in the cold water pipe, and that combined, the flow is 1200 L/hour.

Let's define the flow in the hot water pipe as H liters per hour and the flow in the cold water pipe as C liters per hour. The two given conditions can be translated into the following equations:

To solve for H and C, we can use substitution or elimination method. First, we can solve Equation 1 for H to get:

H = 1.5C

Now, we substitute H in Equation 2 with 1.5C:

1.5C + C = 1200

Combining like terms, we get:

2.5C = 1200

Dividing both sides by 2.5, we find the flow rate of the cold pipe:

C = 1200 / 2.5

C = 480 L/hour

Now we can substitute C back into the equation for H to find the hot water flow:

H = 1.5 * 480

H = 720 L/hour

Therefore, the flow rate in the hot water pipe is 720 L/hour, and the flow rate in the cold pipe is 480 L/hour.

Answer:

Step-by-step explanation:

Step 1:  rewrite the equation of the given line in to slope-intercept form by solving for y

  3y + 5x = 6    

     3y = -5x + 6               (subtract 5x from both sides)

        y = -(5/3)x + 2           (divide both sides by 3)

Step 2:  Our line is parallel to this line, so it has the same slope, and a

y-intercept of 4, so we have...

  y = -(5/3)x + 4      

*slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept,

The  experimental probability of spinning a number greater than 3 is 2/5

It is a branch of mathematics that deals with the occurrence of a random event.

The total times spun is 14+12+16+15+13

We get 70

Add all of the times spun to get 70. To get 16/70 then divide by 2 to get 8/35.

The spun greater than three are 15+13

which is 28

Now Probability of an Event P(E) = Number of times an event occurs / Total number of trials.

=28/70

=14/35

=2/5

Hence, the  experimental probability of spinning a number greater than 3 is 2/5

Final answer:

The question asks to solve two inequalities resulting from the product of -5 and a number being greater than 35 or less than 10. The solution reveals the number must be either smaller than -7 or greater than -2.

Explanation:

The student's question relates to an inequality involving multiplication with a negative number. The statement 'the product of -5 and a number is greater than 35 or less than 10' can be translated into two separate inequalities because of the 'or.' They are as follows:

-5x > 35

-5x < 10

To solve these inequalities, you would divide each side by -5. Remember the rule: when you divide or multiply an inequality by a negative number, you must flip the inequality sign.

For -5x > 35:

x < -7

For -5x < 10:

x > -2

Therefore, the number must be either smaller than -7 or greater than -2.

Hence,

Final answer:

After calculating the absolute value of (2-5) which is 3, and (8-11) which is -3, we conclude that |2-5| is greater than (8-11), so the right comparison operator is '>'.

Explanation:

The student is asking to compare the absolute value of the difference between 2 and 5 with the difference between 8 and 11 using one of the comparison operators: less than (<), greater than (>), or equal to (=). The absolute value of a number is the non-negative value of that number without regard to its sign. The difference of two numbers is calculated by subtracting the second number from the first one.

To solve the given comparison |2-5| ? (8-11), first, we find the value of each expression. The absolute value of (2-5) is |2-5| = |-3| = 3 because the absolute value of a negative number is its positive counterpart.

For the second expression, (8-11), we simply subtract 11 from 8 to get 8-11 = -3. Now we compare 3 and -3. Since 3 is greater than -3, we can conclude that 3 > -3.

Therefore, |2-5| > (8-11).

60 feet in 1.5 hours vs. 90 feet in 2.5 hours

Now, put the distance travelled by each in the same amount of time. You can reduce these to one hour each, or you can multiply both by a common denominator to save some fraction work (the first CD I can calculate is 30 hours, so multiply each fraction by the necessary number to bring the denominator to 30).

(60 feet/1.5 hours) x 15 = 900 ft/30 hours

(90 feet/2.5 hours) x 12 = 1080 ft/30 hours

1080 feet in 30 hours is greater than 900 feet in 30 hours, so 90 feet in 2.5 hours is faster than 20 yards in 1.5 hours.
