Sin 0 = -3/5 and cos 0 > 0. Identify the quadrant of the terminal side of O and find cos 0.

Mathematics
1 answer:
NARA [144]3 years ago
3 0

Answer:

See below.

Step-by-step explanation:

Cos O is positive in the first and 4th quadrants and sin O is negative in the 3rd and 4th quadrants.

So the answer is Quadrant 4.

cos^2 O = 1 - sin^2 O

= 1 - (-3/5)^2

= 16/25

So  cos O  is +√(16/25)

= 4/5.

kumpel [21]

Answer: A. 4(8x + 2), and C. 32x + 8

Step-by-step explanation:

Put the equations together and if they have infinitely many solutions they'll both be equal to each other.

CORRECT 4(7x + 2 + x)=4(8x + 2)

7x+2+x=8x+2

8x+2=8x+2 (Infinitely Many Solutions)

CORRECT 4(7x + 2 + x)=32x+8

4(8x+2)=32x+8

32x+8=32x+8

32x+8=32x+8 (Infinitely Many Solutions)

INCORRECT 4(7x + 2 + x)=4(7x + 3)

8x+2=7x+3

8x=7x+1

8x−7x=1

x=1

INCORRECT 4(7x + 2 + x)=28x + 12

4(8x+2)=28x+12

32x+8=28x+12

32x=28x+4

32x−28x=4

4x=4

x=1

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Use the law of cosines to find the value of cos theta. round your answer to two decimal places
REY [17]

<u>Answer:</u>

The correct answer option is B. 0.21.

<u>Step-by-step explanation:</u>

We are to find the value of cos \theta using the law of cosines.

We know that the formula of the cosine rule is given by:

c ^ 2 = a ^ 2 + b ^ 2 - 2 a b cos C

So substituting the given values in the above formula:

10.9 ^ 2 = 5.8 ^ 2 + 10.5 ^ 2 - 2 (5.8) (10.5) cos C

118.81=33.64+110.25-121.8cosC

118.81 - (33.64+110.25) = -121.8cosC

118.81-143.86=-121.8cosC

cosC=\frac{-25.05}{-121.8}

cos C = 0.21

What is the x-intercept of the line with the equation <br><br> 8x-1/3y=16
swat32
X-intercept is the value of x when y = 0.
8x - 1/3y = 16
8x - 1/3(0) = 16
8x = 16
x = 16/8 = 2.
x-intercept = (2, 0)

What is the answer to this inequality question 2(4x+1)&lt;3(2x-3)
Nikitich [7]

Answer:

x < -7

Step-by-step explanation:

2(4x + 1) < 3(2x - 3)

Distributive Property:

8x + 8 < 6x - 6

Subtract on Both Sides:

8x + 8 < 6x - 6

- 6x       -6x

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

2x + 8 < - 6

      -8    -8

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

2x < -14

Divide on Both Sides:

2x < -14

---     ---

2        2

x < -7
