What is cos 0 when sin 0
taurus [48]

Answer:

Cos θ = √7/3

Step-by-step explanation:

From the question given above, the following data were obtained:

Sine θ = √2 / 3

Cos θ =?

Recall

Sine θ = Opposite / Hypothenus

Sine θ = √2 / 3

Thus,

Opposite = √2

Hypothenus = 3

Next, we shall determine the Adjacent. This can be obtained as follow:

Opposite = √2

Hypothenus = 3

Adjacent =?

Hypo² = Adj² + Opp²

3² = Adj² + (√2)²

9 = Adj² + 2

Collect like terms

9 – 2 = Adj²

7 = Adj²

Take the square root of both side

Adjacent = √7

Finally, we shall determine the value Cos θ. This can be obtained as follow:

Adjacent = √7

Hypothenus = 3

Cos θ =?

Cos θ = Adjacent / Hypothenus

Cos θ = √7/3

I need your help please!
Aneli [31]

Answer:

1 mile is mapped to 0.3428 inches i.e. unit rate is 0.3428 inches/mile.

Step-by-step explanation:

Given that the scale of the map is \frac{3}{10} inches = \frac{7}{8} miles ....... (1)

Now, we have to convert this map scale to a unit rate.

And the unit rate is the number of inches per mile.  

As the scale is constant, therefore from the the relation (1) we get  

1 mile = \frac{3 \times 8}{10 \times 7} = 0.3428 inches.

Therefore, 1 mile is mapped to 0.3428 inches i.e. unit rate is 0.3428 inches/mile.  (Answer)

Solve -52 = 4m for m
ZanzabumX [31]

Note the equal sign. What you do to one side, you do to the other.


Isolate the variable. Divide 4 from both sides


(-52)/4 = (4m)/4


m = -52/4


m = -13


-13 is your answer for m



hope this helps
