Identify the percent of change (POC) as an increase or decrease. Then find the percent of change. Round to the nearest tenth of

a percent if necessary.
-12 inches to 36 inches
-50 punds to 35 pounds
-10 gallons to 24 gallons
-16 centimeters to 44.2 centimeters

If you could explain this as simple as possible with the work, for I have problems understanding things well, then that would be a HUGE help!

If you can answer all 4, I'm awarding 20 points!!

Percent change=(change/original) tiimes 100 change= |original-new| so 12 to 36 |12-36|=|-24|=24 so pcercent change=100 times (24/12)=100 times 2=200% 50 to 35 |50-35|=|15|=15 percent change=100 times (15/50)=100 times 100 times 0.30=30% 10 to 24 |10-24|=|-14|=14 percent change=100 times (14/10)=100 times 1.4=140% 16 to 44.2 |16-44.2|=|-28.2|=28.2 percent change=100 times (28.2/16)= 100 times 1.7625=176.25% answers are -12 inches to 36 inches: 200% -50 punds to 35 pounds: 30% -10 gallons to 24 gallons: 140% -16 centimeters to 44.2 centimeters: 176.25%

P= 14413.49<br> R= 0.0015<br> T= 36<br><br> What is I= Prt
tamaranim1 [39]

Answer: I = 778. 33

Step-by-step explanation:

P= 14413.49

R= 0.0015

T= 36

The formula for calculating interest is given as :

I = PRT

substituting the given values , we have :

I = 14413.49 x 0.0015 x 36

I = 778.32846

I = 778. 33

(5ab-4a-6)-(4ab-1) find the sum please fast
jekas [21]

We need to get rid of expression parentheses.

If there is a negative sign in front of it,

each term within the expression changes sign.

Otherwise, the expression remains unchanged.

Numerical 'like' terms will be added. There is only one group of like terms

the answer is: ab-4a-5

Consider the function f given by f(x)=x*(e^(-x^2)) for all real numbers x.
NISA [10]

Answer:

\frac{\sqrt{\pi}}{4}

Step-by-step explanation:

You are going to integrate the following function:

g(x)=x*f(x)=x*xe^{-x^2}=x^2e^{-x^2}  (1)

furthermore, you know that:

\int_0^{\infty}e^{-x^2}=\frac{\sqrt{\pi}}{2}

lets call to this integral, the integral Io.

for a general form of I you have In:

I_n=\int_0^{\infty}x^ne^{-ax^2}dx

furthermore you use the fact that:

I_n=-\frac{\partial I_{n-2}}{\partial a}

by using this last expression in an iterative way you obtain the following:

\int_0^{\infty}x^{2s}e^{-ax^2}dx=\frac{(2s-1)!!}{2^{s+1}a^s}\sqrt{\frac{\pi}{a}} (2)

with n=2s a even number

for s=1 you have n=2, that is, the function g(x). By using the equation (2) (with a = 1) you finally obtain:

\int_0^{\infty}x^2e^{-x^2}dx=\frac{(2(1)-1)!}{2^{1+1}(1^1)}\sqrt{\pi}=\frac{\sqrt{\pi}}{4}
