Answer:

1. Wind is the horizontal movement of air. All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion, Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.

2. Local winds blow between small low and high pressure systems. Local winds blow over a very limited area, while large scale winds blow over very unlimited area.

Suppose that the amount, in grams, of polonium 210 present in a given sample is determined by the function defined by A(t)equ

ozzi

Answer:

The amount present in a sample of 401 grams after 25 years is $180\ g$

Step-by-step explanation:

we have

A(t) -----> the amount, in grams, of polonium 210 present in a given sample

t -----> the time in years

$A(t)=401e^{-0.032t}$

we know that

To find out the amount present in a sample of 401 grams after 25 years, substitute the value of t=25 years in the equation and solve for A(t)

For t=25 years

$A(25)=401e^{-0.032(25)}$

$A(25)=180.18\ g$

If that is = a, find the value of a + 1 over a<br><img src="https://tex.z-dn.net/?f=3%20-%20%20%5Csqrt%7B5%7D%20" id="TexFormula

Doss [256]

Answer:

7+√5/4

Step-by-step explanation:

if that is = a, find the value of a + 1 over a

Given that a = 3 - √5

a+1/1 = (3-√5)+1/3 - √5

4-√5/3 - √5

Rationalize

4-√5/3 - √5 * 3+√5/3 + √5

= 12 +4√5-3√5-√25/9-5

= 12+√5-5/4

= 7+√5/4

Hence the requred answer is 7+√5/4

$f(x) = -0.26x^2 + 1.2x + 5.7\\\\\\f'(x)=(-0.26x^2 + 1.2x + 5.7)'=(-0.26x^2)'+(1.2x)'+(5.7)'=\\\\=-0.26(x^2)' + 1.2(x)' + (5.7)'=-0.26\cdot(2x) + 1.2\cdot1+0=\\\\=\boxed{-0.52x+1.2}$
