What is the value in meters per second squared of the acceleration of gravity?

Lady bird [3.3K]

In real-life physics, acceleration due to gravity will change respect to altitude. Check out the attached image (source: Wikipedia).

However, in high-school physics, acceleration due to gravity is represented by the letter g, which has a value of 9.81 meters per second squared.

This means that an object being dropped straight down will be moving 9.81 meters per second faster than it was 1 second ago. I hope this helps! :)

Solving multi-step <br> 2(8+4c)=32 <br>c=

professor190 [17]

You’re gonna multiplying & you do that it would be 16+ 8c= 32 and then you subtract 16 from 32 and that gives you 8c = 16 and you dived and C = 2

Suppose that prior to conducting a coin-flipping experiment, we suspect that the coin is fair. How many times would we have to f

BabaBlast [244]

Answer:

153 times

Step-by-step explanation:

We have to flip the coin in order to obtain a 95.8% confidence interval of width of at most .14

Width = 0.14

ME = $\frac{width}{2}$

ME = $\frac{0.14}{2}$

ME = $0.07$

$ME\geq z \times \sqrt{\frac{\widecap{p}(1-\widecap{p})}{n}}$

use p = 0.5

z at 95.8% is 1.727(using calculator)

$0.07 \geq 1.727 \times \sqrt{\frac{0.5(1-0.5)}{n}}$

$\frac{0.07}{1.727}\geq sqrt{\frac{0.5(1-0.5)}{n}}$

$(\frac{0.07}{1.727})^2 \geq \frac{0.5(1-0.5)}{n}$

$n \geq \frac{0.5(1-0.5)}{(\frac{0.07}{1.727})^2}$

$n \geq 152.169$

So, Option B is true

Hence we have to flip 153 times the coin in order to obtain a 95.8% confidence interval of width of at most .14 for the probability of flipping a head

I know that x=0 but I don't know how I really got that.

galina1969 [7]

Sqrt(x+4-3)=1
sqrt (x+1) = 1
x+1 = 1^2
x=1-1
x=0

This is how you would get x=0

Hope I helped :)

Combine the like to simplify the expression: -5y + 12 + 8y − 6 − 2 =

ANTONII [103]

First, let's move combine like terms:

-5y + 8y = 6 + 2 -12.

3y = -4.

y = -4/3
