Both. They're both used all the time, sometimes the question is in radians and other times its in degrees. Mine is mostly on degrees though.

Manco went scuba diving. As he dove deeper, the water pressure around him increased at a constant rate.
vovikov84 [41]

Answer:

0.1 atmospheres per meter

Step-by-step explanation:

Depth (meters) = x

Pressure (atmospheres) = y

Using two pairs of values from the table, (13, 2.3) and (17, 2.7),

Rate of change of the water pressure = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2.7 - 2.3}{17 - 13} = \frac{0.4}{4} = 0.1

Rate of change of the water pressure = 0.1 atmospheres per meter

The sum of two numbers is 58. If there difference is 28, find both numbers
just olya [345]

Answer:

y = 15

x = 43

Step-by-step explanation:

this is giving us a system of equations because we know two things:

x + y = 58

x - y = 28

take the second equation and format it where you have simplified it for one variable:

x = 28 + y

(we did this by adding y to both sides)

now substitute this new value of x into the <em>first </em>equation:

28 + y + y = 58

simplify this to get 2y = 30

divide both sides by 2: y = 15

now substitute your new value of y into the <em>second </em>equation:

x = 28 + 15

x = 43

Vesnalui [34]

Answer:

Step-by-step explanation:

To solve this, we would use the formula for calculating simple interest which is:

Interest = PRT

Then, we will slot in the values given which will be:

84 = P × 3% × 7

84 = P × 0.03 × 7

84 = 0.21P

P = 84/0.21

P = $400

The Principal is $400
