Disregarding wind resistance the distance a body falls from rest varies directly as th squares of the time it falls if a skydive

Firdavs [7]

Answer:

The skydiver will fall 1600 ft in 10 seconds.

Step-by-step explanation:

Distance a body falls from rest varies directly as the squares of the time it falls

Let distance = s

time = t

Therefore , s = k $\times t^{2}$

Given, the body falls 64 ft in 2 seconds.

Substituting in above equation,

64 = k $\times (2)^{2}$

64 = k $\times (4)$

k = $\frac{64}{4}$

k = 16 ft/ $s^{2}$

We have to find how much he will fall in 10 seconds.

s = k $\times t^{2}$

s = $16 \times 10^{2}$

s = $16 \times 100$

s = 1600 ft

If methane at a pressure of 3.2 atm and at 21 °C is introduced into a container, the gas be heated to ______°C to increase the p

Veronika [31]

A: 3.2/294=12/T
T=1102.5 K 
*** 
*** 
b: V/T => V/1088 = 4000/294 
V = 14802.7 L = 14.8 m^3 
*** 
*** 
c. 
pV/T 
1.1*V/294 = 12*15000/1088 

V= 48.64 m^3

Can someone help me with this question please. I'll give the brainliest answer to whoever helps me.

Doss [256]

Answer: $\sqrt[5]{y}$

I realize its probably not the largest readable font. If you are having trouble reading it, it is the square root of y; however, there is a tiny little 5 in the upper left corner to indicate a fifth root. So you would read it out as "the fifth root of y"

The rule I'm using is

$x^{1/n} = \sqrt[n]{x}$

and the more general rule we could use is

$x^{m/n} = \sqrt[n]{x^m}$

where m = 1. This rule helps convert from rational exponent form (aka fractional exponents) to radical form.

A coin is tossed and an eight-sided die numbered 1 through 8 is rolled. Find the probability of tossing a head and then rolling

ratelena [41]

Answer: 7/8

Step-by-step explanation:

Probability is calculated by number of possible outcomes/ total outcomes

From the question, a coin only has two sides, Head or Tail. Total outcomes is therefore equal to 2

Possible outcome is to toss a head, which is one event

Probability of tossing a head is therefore =1/2

The second part of the question is rolling a die with eight sides.

Here, the die is said to have eight sides, 1,2,3,4,5,6,7,8. Total outcomes is therefore equal to 8

Possible outcome of rolling a number greater than 5 is 3 possibilities, that is rolling 6, 7 and 8.

Pr(rolling > 5) is 3/8

Therefore, Pr ( head; rolling > than 5)

= 1/2 + 3/8

=7/8

I hope this is clear, please mark as brainliest answer

PLEEASE HELP!!!! I WILL GIVE BRAINLIEST!!!!!

Vika [28.1K]

Answer:

7

Step-by-step explanation:

Set up an equation using slope intercept form.

y = mx + b

75 = 8x + 15

Solve.

75 = 8x + 15

-15 -15

60 = 8x

7.5

Round down as it is dealing with money and he would not have enough to purchase an 8th grocery.

7 is the final answer.

Hope this helps!
