Which trigonometric functions are negative in the fourth (IV) quadrant?

### Answers

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.

Answers are: sine, tangent, cosecant, cotangent

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.

how much money must be deposited now in an account paying 7% annual interest compounded yearly to have a balance of $1000 after 6 years

### Answers

Answer: P = $70.42

Step-by-step explanation:

Equation:

P = A / (1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 7%/100 = 0.07 per year.

Solving our equation:

P = 100 / ( 1 + (0.07 × 6)) = 70.422535211268

P = $70.42

The principal investment required to get a total amount, principal plus interest, of $100.00 from simple interest at a rate of 7% per year for 6 years is $70.42.

What is the solution set to this inequality, where x is a real number: -4x (less than or equal to ) 36

### Answers

Since it’s an inequality you will NOT be looking for what X equals.

Starting with -4x or =) -9

Answer:

The answer is negative nine

Step-by-step explanation:

When it comes to x = ?, divide the ANSWER by the mulitplicand. Example, -4x = 36 can be translated to 36 = -4 TIMES X, which here you have to use your head. Negatives cancel each other and the answer is positive, therefore -4 * -9 = 36.

Consider two parallel line segments. Part A: Find the slope of segment CD with endpoints C(−5, 4) and D(2, 1). Show your work. (2 points)

Part B: What is the value of y so that segment AB with endpoints A(−6, y) and B(1, −5) is parallel to segment CD question mark Show your work. (2 points)

### Answers

Answer:

Part A: -3/7

Part B: y = -2

Step-by-step explanation:

Parallel lines have the same slope. Find the slope of CD. Then substitute it to find the value needed for AB.

The slope formula is

Use the same formula and solve for y.

A triangle has side lengths 14,48, and 50 is it an acute angle an obtuse angle a right angle or no solution.

### Answers

Answer:

No solution, a triangles angles must measure up to 180 degrees, and that clearly isnt close to it. Therefore, the answer is no solution. An obtuse is an angle greater than 90 degrees, whereas an acute is less.

Step-by-step explanation:

Determine which ordered pair is not a solution of y=-5x-4 a. (10,-52) b.(7,-39)c.(-7,31) d(8,-44)

### Answers

Answer:

A

Step-by-step explanation:

An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.

y = -5x - 4

Test:

-52 = -5(10) - 4

-52 = -54 FALSE

-39 = -5(7) - 4

-39 = -39 TRUE

31 = -5(-7) - 4

31 = 31 TRUE

-44 = -5(8) - 4

-44 = -44 TRUE

A local dairy farmer collects 490 gallons of milk from his cows. He keeps 1/35 of the milk for his own use, and sells the rest. Each quart of milk sells for 35 cents. In dollars, how much does he earn from selling his milk each day?

### Answers

Answer:

666.4 dollars per day

Step-by-step explanation:

Total milk farmer has is 490 gallons

He keeps 1/35 of 490 gallons

so he keeps = 1/35*490= 14 gallons

He sells remaining milk.

Remaining milk = 490-14 = 476 gallons

1 gallon = 4 quart (conversion formula)

so 476 gallon = 4 * 476 = 1904 quart

selling price of 1 quart = 35 cents = 0.35 dollars

so selling price of 1904 quart = 0.35*1904 = 666.4 dollars

So he makes 666.4 dollars per day.

What is the solution set to this inequality, where x is a real number: -4x

### Answers

Answer:

x ≥ 9

Step-by-step explanation:

Considering the equation is;

-4x (less than or equal to ) 36 , as provided by the questioner;

-4x ≤ 36

Dividing both sides by -4

-4x/-4≤ 36/-4

We get;

x ≥ -9 , the sign ≤ changes to ≥ since we have divided by a negative.

x ≥ 9

What is the definition of Transformants in geometry

### Answers

Answer:

Step-by-step explanation:

Geometric transformations involve taking a preimage and transforming it in some way to produce an image. There are two different categories of transformations:

The rigid transformation, which does not change the shape or size of the preimage.

The non-rigid transformation, which will change the size but not the shape of the preimage.

keep in mind that there's 4 types of transformants!!!

- Rotation
- Translation
- Dilation
- Reflection
