Hello!</h2>
The answer is: 4.0 (at Richter scale)
<h2>Why?</h2>
The answer is 4.0 Assuming the standard earthquake as 1.0 (at Richter scale).
An earthquake of 1.0 at Richter scale is equal to:
An earquake of 2.0 at Richter scale is equal to:
and so...
Therefore,
An earthquake of 4.0 at the Richter scale is equal to:
So, it means that an earthquake with 4.0 magnitude at the Richter scale is 10000 times more intense than a standard earthquake, assuming it as 1.0 at Richter scale magnitude.
Have a nice day!
Answer:
The rate of change of each circular surface of the dough is approximately 150.796 in.²/minute
Step-by-step explanation:
The given parameters are;
When the radius of the dough, r = 12 inches, the radius is increasing at 2 inches per minute
Therefore, we have;
dr/dt = 2 in./min
The area of the circular surface of the dough, A = π·r²
The rate of change of each (top or bottom) circular surface area of the dough dA/dt is given as follows;
dA/dt = d(π·r²)/dt = π·2·r·dr/dt
Where;
r = 12 in.
dr/dt = 2 in./min
Substituting, we have;
dA/dt = π·2·r·dr/dt = π × 2 × 12 in. × 2 in./min ≈ 150.796 in.²/minute.
The rate of change of each circular surface of the dough = dA/dt ≈ 150.796 in.²/minute.
Answer:
<em>A) The reference angle should be </em><u><em>,</em></u><em> and the sign of the value should be </em><u><em>negative.</em></u>
Step-by-step explanation:
cos()
Remove full rotations of 2π until the angle is between 0 and 2.
cos()
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the third quadrant.
-cos()
The exact value of cos() is .

Answer:
14
Step-by-step explanation:
Since we're given the conversion 24 cm for every 3 presents wrapped, we can divide our total amount of tape by this conversion, assuming a constant proportion.
Evren has 112 cm of tape. We can write the following proportion:
, where is the number of presents he can wrap with 112 cm.
Cross-multiplying, we have:
0 so tthis one is soo easy since their is a lot of 0 which means nothing and their is 23 as a number so it is 23 precent can u give me points plzz
