6 0
A. Man runs (> 2.2 m/s is running) uphill at 6 m/s (???) and decelerates to walking at 2.0 m/s near the top, all in 5 minutes, assuming he ran in a straight line.

Acceleration is (final velocity-initial velocity (m/s) )/time (s)
=(2-6)/(5*60)=-4/300= -0.0133 m/s^2

B. Car goes east for 300 km in 45 min.
Velocity 
=300*1000 m  / (45*60) s  due east
=300000/2700 m/s due east
=111.1 m/s due east
(is it an airplane?  A cesna cruises at 63 m/s  (226 km/h) )

1. How do you use the distance formula and slope formula to classify a quadrilaterals and triangles
4vir4ik [10]

Answer:

Both Distance formula and Slope formula are used to classify quadrilaterals and triangles, as Distance formula is used to calculate the length of each side while Slope formula is used to find the angle of a line with respect to an axis or another line.

We can classify the figure as finding the lengths of each side by using Distance formula. For example, if we find that a quadrilateral has all 4 sides equal, is it a square. If it has opposite sides equal, it can be a rectangle or a parallelogram, and so on. It can also tell whether a triangle is right angled, isosceles or equilateral.

Slope are used to find angles of the lines. If 2 lines have the same slope, it means they are parallel to each other. If the product of their slopes is -1, it means they are perpendicular to each other

Gabriel has 15 5/8 pound of clay. He will use 7/10 pounds to make each bowl. After making 8 bowls, Gabriel wonders how many more
Pie
You would begin by multiplying 7/10 by 8 to get 5 3/5. then you would subtract 5 3/5 from 15 5/8 to get the remaining amount of clay after the eight bowls (401/40). lastly, divide the remainder of the clay by 7/10 to get the number of bowls that could be made with it - which is 14. the actual answer has a decimal, but you must have a whole number in order to make an entire bowl. you can check this by multiplying 7/10 by 22 (for the total number of bowls) and you get 15 2/5

You invest $2,000 in an account that has an annual interest rate of 3.2%, compounded annually. How much money will be in the acc
MissTica
P = 2000 is the amount invested
r = 0.032 is the decimal form of 3.2%, which is the interest rate
n = 1 indicates we compound 1 time a year (compound annually)
t = 12 is the number of years

Those four values are plugged into the formula below
A = P*(1+r/n)^(n*t)
A = 2000*(1+0.032/1)^(1*12)
A = 2918.6792
A = 2919

Rounded to the nearest whole dollar, you'll have about $2919 in the account
