Two math students were asked to write an exponential growth equation that had a starting value of 300 and a growth rate of 2%. P
Gemiola [76]

Answer:

Pierre is right

Step-by-step explanation:

The correct formula for Exponential growth rate is given as:

y = a( 1 + r) ^t

Where

y = Amount after time t

a = Initial amount

r = Growth rate

t = time

From the question

a = 300

r = 2% = 0.02

Hence, our exponential growth rate =

y = 300( 1 + 0.02)^t

y = 300( 1.02)^t

Therefore, Pierre is right

Complex numbers simplify square roots of negative numbers
Bogdan [553]

Lets do

\\ \sf\longmapsto \sqrt{-100}

\\ \sf\longmapsto \sqrt{-(10)^2}

\\ \sf\longmapsto \sqrt{10^2}\sqrt{-1}

\\ \sf\longmapsto 10i

Write in standard form

\\ \sf\longmapsto 10i

\\ \sf\longmapsto \boxed{0}+\boxed{10}i

Simplify: <br> −(−3)2(5)2(7)3<br> 152<br><br> A) -343 <br> B) -127 <br> C) -75 <br> D) 126
Lilit [14]

Answer:

If I read your problem write:  126

Step-by-step explanation:

if I interpret this as

- (-3)* 2 * (5) * 2 * (7) * 3  divided by 5 * 2

we can get  126

because:

- (-3)* 2 * (5) * 2 * (7) * 3  divided by 5 * 2

= 6 * 5 * 2 *7 * 3 / (5*2)

= 60*7 * 3/ (5*2)

= 420 * 3 / 10

= 1260/10

= 126
