Answer:
I belive it is c
Step-by-step explanation:
To write 3482000000 in scientific notation. Put down the first number (3) and all numbers that come after it (not 0) put after a decimal point. Then count all of the numbers after the decimal points including 0's and that's your exponent. Like so,
3.482*10^9
Hope this helps!=)
-4<x<6
should be the correct answer because x is larger than -4 but 6 is larger than x.
you could also write it
-4<x AND x<6
Answer:
0.1, 1/2, 0 .7 , 3/4
Step-by-step explanation:
3/4, 0.7, 1/2 , 0.1
Change the numbers to the same form
3/4 = .75 1/2 = .5
.75 , .7 , .5 , .1
We want the numbers from least to greatest or smallest to biggest
.1 is the smallest
then .5
then .7
then .75
Changing the numbers back to the original form
0.1, 1/2, 0 .7 , 3/4
A ) v = v o + g t
h = v o * t + g t² /2
10 m = 9.81 m/s² * t² / 2
9.81 t² = 20
t² = 2.038
t = 1.4278 s
v = 0 + 9.81 * 1.4278
v = 14 m/s
b ) v o = 14 m/s
v = v o² + 2 a d
0 = 14² + 2 a * 2.9
196 = - 5.9 a
a = 196 : ( - 5.9 )
a = - 33.79 m/s² ( the magnitude of his acceleration while in water )
c ) The total amount of force exerted on the swimmer in water:
F = m * a = 65 kg * 33.76 m/s²
F = 2,196.55 N
