A falling object accerlates from -10.0m/s to -30.0m/s how much time does that take

Mathematics
1 answer:
Leya [2.2K]3 years ago
5 0

Answer:

2.04 seconds

Step-by-step explanation:

Falling objects near the surface of the earth have an acceleration of -9.81 m/s².

Acceleration is the change in velocity over change in time:

a = (v − v₀) / t

-9.81 = (-30.0 − (-10.0)) / t

-9.81 = -20.0 / t

t = 2.04

It takes 2.04 seconds.

N (blank exponent) = 1/64 when n = 1/4
gizmo_the_mogwai [7]

Answer:

The blank exponent is 3

Step-by-step explanation:

It is given that n^x=1/64 where n=1/4

1/4^x=1/64

1/4*1/4*1/4=1/64, so x=3 works as a solution. You could use logarithms, but it makes things more difficult, especially in this case.

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
umka21 [38]

Answer:

2/9

12.5%, 30% ,45%

Step-by-step explanation:

Possible outcomes

W = wild

S = sandy shores

G = green hills

W6  W7   W10

S6  S7   S10

G6  G7   G10

There are 9 outcomes

2 are over a week without hills  (W10 and S10) and

P(10 days not at hills) = # more than 7 days no hills/total

                                               =2/9

We need all the numbers in the same form, I will change to decimal

1/8 = .125

30% = .30

.45

Smallest to largest

.125 <.30 <.45

1/8 < 30% < .45

Changing to percent form

12.5%, 30% ,45%
