You can use the identity
cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.
(1/4)² +sin(x)² = 1
sin(x)² = 1 - 1/16
sin(x) = ±(√15)/4
Then the tangent can be computed as the ratio of sine to cosine.
tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
tan(x) = ±√15
There are two possible answers.
In the first quadrant:
sin(x) = (√15)/4
tan(x) = √15
In the fourth quadrant:
sin(x) = -(√15)/4
tan(x) = -√15
Answer:
0.23 or 0.230
Step-by-step explanation:
You can round it by looking at the hundredths place.
Look to the thousandths place, if its 5 or more, you round up, if its 4 or less you round down.
Answer:
x - 3/4 is a zero
Step-by-step explanation:
f(x) = x+3/4
To find the zeros, set f(x) =0
0 = x+3/4
Solve for x
Subtract 3/4 from each side
0-3/4 = x+3/4-3/4
-3/4 =x
The zero is -3/4
No of coins Sparrow had in the beginning 92 coins
Step-by-step explanation:
Total coins = 210
Current ratio = 4:5:6
It implies 210 needs to be split into 15 parts (4+5+6)
So, each part = 210/15 = 14 coins
Again which implies 14*4 : 14*5 : 14*6 = 56 : 70 : 84
So before the game began,
No of coins Ahab had = (56 - 5) = 51
No of coins Davy had = (84 - 7) = 67
Hence, No of coins Sparrow had = (210 - 51 - 67) = 92 coins
Answer:
<h3>The answer is 4.47 g/cm³</h3>
Step-by-step explanation:
The density of a substance can be found by using the formula

From the question
mass = 14.3 g
volume = 3.2 cm³
We have

We have the final answer as
<h3>4.47 g/cm³</h3>
Hope this helps you
