4 0

for all of these, you just have to divide by -1 to make the variable positive however you have flip the inequality sign when you divide by a negative number.

c > 1

-2 > v

y > 1

z > 6

1 > w

A biologist is researching a newly-discovered species of bacteria. He puts 1,000 bacteria into what he has determined to be a fa

Svetradugi [14.3K]

The bacteria grow from 1,000 bacteria into 12,500 bacteria in 12 hours. The exponent function would be:

an= ao(1+r)^t
12.500= 1,000(1+r)^12
1,000(12.5)= 1,000(1+r)^12
12.5= (1+r)^12
1+r= 1.23427
r= 0.23

Number of bacteria after 20hr would be:
an= ao(1+r)^t
an= 1,000(1+0.23)^20
an= 1,000(62.821 )
an= 62,821

(3x^4y^5) ^ 3/7 in radical form

kobusy [5.1K]

The expression in radical form is $(\sqrt[7]{3x^4y^5}) ^3$

In order to express the given indices expression in radical form, we need to ensure there is a square root present in the resulting expression.

According to the law of indices,

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