Find the radian measure of an angle of -280°

Bingel [31]

To convert an angle from degrees to radians, multiply by π/180°.

Your angle is
(-280°)*(π/180°) = -14π/9

The appropriate choice is ...
B) (-14π/9)

Differentiation with respect to time

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Step-by-step explanation:

Step 1: Define

$\displaystyle l = 10 \ meters$

$\displaystyle \frac{dl}{dt} = 4 \ m/day$

$\displaystyle w = 23 \ meters$

$\displaystyle \frac{dw}{dt} = 1 \ m/day$

Step 2: Differentiate

[Area of Rectangle] Product Rule: $\displaystyle \frac{dA}{dt} = l\frac{dw}{dt} + w\frac{dl}{dt}$

Step 3: Solve

[Rate] Substitute in variables [Derivative]: $\displaystyle \frac{dA}{dt} = (10 \ m)(1 \ m/day) + (23 \ m)(4 \ m/day)$
[Rate] Multiply: $\displaystyle \frac{dA}{dt} = 10 \ m^2/day + 92 \ m^2/day$
[Rate] Add: $\displaystyle \frac{dA}{dt} = 102 \ m^2/day$

The spinner below is spun, then a month of the year is randomly selected. Find the probability of P(unshaded, then a month that

lana [24]

Answer:

C)150

Step-by-step explanation:

P (blue) fraction = 2/8 decimal=.25 percent=25%

P(purple) fraction=0/8 decimal=0 percent =0%

P(not green) fraction=5/8 decimal=.625 percent= 62.5%

P(not brown) fraction=8/8 decimal=1 percent =100%

2)Refer to the table on air travel selected airports. Suppose a flight that arrived at El Centro is selected at random. What is the probability that the flight did not arrive on time? write your answer as a fraction, decimal and percent.

80% on time so 20% are not on time

20/100 ÷ 20 =1/5

20%, .2, 1/5

3)The spinner has 8 sectors labeled with letters. Each sector of the spinner below is the same size, as shown.

If the arrow is spun 400 times , how many times would it be expected to land on a sector labeled B?

A)50 C)150

B)100 D)250
