In the terminal side of an angle in standard position lies on -4y=3x and x>0, find the exact values of the trigonometric functions of 0

Answers

Answer:

sec ∅  =  5/4

cosec ∅  = -5/3

cot ∅  = -4/3

Tan ∅ = - 3/4

sin ∅   = -3/5

cos ∅   =4/5

Step-by-step explanation:

Given : -4y = 3x  , x > 0

i.e. 3x + 4y = 0 ,  x >0

4y = -3x  ∴ y = - 3/4 x

The values of trigonometric functions of  ∅  are

Tan ∅  = opposite / adjacent

           = - 3/4   ( given that y = slope which is = Tan  ∅ )

now we will find the hypothenuse ( c )

c^2 = a^2 + b^2 = 9 + 16 = 25

therefore ; c = √25 = 5

hence the trig functions are :

sin ∅   = -3/5

cos ∅   =4/5

sec = 5/4

cosec = -5/3

cot = -4/3

Step-by-step explanation:

the common diiference of an ap is 4 . the last term is 72 and the sum of all terms is 600. find the first term and the number of terms​

Answers

Answer:

a = - 24 ; n =25

a = 28 ; n = 25

Step-by-step explanation:

n = l - a/d + 1

d = common difference = 4

Last term = l = 72

n = 72 - a/4 + 1

4n = 72 - a + 4

4n = 76 - a

a = 76 - 4n - - - (1)

Sum of terms :

Sn = n/2(a + l)

Sn = 600

600 = n/2(a + 72)

1200 = n(76-4n +72)

1200 = 148n - 4n

4n² - 148n + 1200

Solving the quadratic equation :

Roots of n are :

12 and 25

From (1)

n = 12

a = 76 - 4(12) = 28

n = 25

a = 76 - 4(25) = - 24

Hence,

a = - 24 ; n =25

a = 28 ; n = 25

Cameron created a composite figure by stacking three cubes the cubes measure 2 inches on each side  what is the volume of the composite figure

Answers

Answer:

24 cubic inches.

Step-by-step explanation:

The volume of one cube = s * s * s or s^3

s = 2 inches

V = s^3

V = 2 * 2 * 2 or 2^3

V = 8 cubic inches.

The volume of 3 of them is 8*3 = 24 cubic inches.

A number increased by 7 is 4 less than twice the number. Write the equation and solve

Answers

Answer:

The number must be bigger than 7 for the equation be true

If you put x= 7 or x= 6...it will not be true

Step-by-step explanation:

x+7< 2x

7< x

x> 7

Example x=9          

9+7 < 2x9

16< 18  TRUE

The equation is x + 7 = 4 - 2x. Then the solution of the equation will be negative 1.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

A number increased by 7 is 4 less than twice the number.

Let the number be 'x'. Then the inequality is given as,

x + 7 = 4 - 2x

Simplify the equation, then we have

x + 7 = 4 - 2x

x + 2x = 4 - 7

3x = - 3

x = -3/3

x = -1

The equation is x + 7 = 4 - 2x. Then the solution of the equation will be negative 1.

Describe all 6 parts, for example, side "a" is one of the legs of the right triangle and is opposite Angle A, which is an acute angle, and side a appears to be the shortest side.

Answers

Answer:

The description of the 6 parts of the right triangle ABC are as follows;

The legs of the right triangle are side "a" and side "b"

The hypotenuse side of the right triangle is side "c"

The acute angles are ∠A and ∠B

The 90° angle is ∠C

The description of the 6 parts are therefore given as follows;

1) A; ∠A is the acute angle opposite side "a" and ∠A is formed between the hypotenuse side "c" and the leg "b"

2) B; ∠B is the acute angle opposite side "b" and ∠B is formed between the hypotenuse side "c" and the leg "a"

3) C; ∠C is the 90° angle (right angle) opposite the hypotenuse side "c" and ∠C is formed between the the two legs "a" and "b"

4) a; Side "a" is one of the two legs of the right triangle ΔABC and it is the leg opposite to ∠A

5) b; Side "b" is one of the two legs of the right triangle ΔABC and it is the leg opposite to ∠B

6) c; Side "c" is the hypotenuse side of the right triangle ΔABC and it (the hypotenuse side) is (all the time) the longest side of the right triangle and it is the leg opposite to ∠A
