Two planes are flying away from Toronto Pearson International Airport. The Air Canada
erica [24]

Answer:

1832 miles

Step-by-step explanation:

First we need to find the angle between the routes of the planes.

If one is N30°W and the other is S45°W, we can find the angle between the routes with the following equation:

30 + angle + 45 = 180

angle = 105°

Then, we need to find the distance travelled by each plane, using the formula:

distance = speed * time

The time is 1.5 hours, so we have that:

distance1 = 800 * 1.5 = 1200 km

distance2 = 750 * 1.5 = 1125 km

Now, to find the distance between the planes, we can use the law of cosines:

distance^2 = 1200^2 + 1125^2 - 2*1200*1125*cos(105)

distance^2 = 3356214.43

distance = 1832 miles

Please help I don't understand exponents
Mkey [24]

Answer:

1.)  the answer is the fourth one, 1/5^7

2.)  the answer is the fourth one, 1/5^6

3.)  the answer is the fourth one, (2^6)^-5

4.) this is seems to be a duplicate of the first one

Step-by-step explanation:

1.) by 'adding' 4 exponent values on the top it simplifies the top to simply one and 5^7 on the bottom

2.) since this is an exponent of an exponent multiply them, getting 5^-6, then simplify negative exponents.

3.) exponents of exponents are multiplied
