Correct answer is 35, because complementary angles are angles whose sum adds up to 90 degrees. So you subtract the 55 from 90, giving you the answer of 35. Since they are complementary this makes the total 90, therefore it is the correct answer!

Fred placed 3 strands of bacteria in a petri dish. The bacteria strands double every hour. Write a formula to represent how many

miv72 [106K]

Answer:

C. $f(n) = 3(2)^n$ ; 48 strands of bacteria

Step-by-step explanation:

Fred placed 3 strands of bacteria in a petri dish.

The bacteria strands double every hour.

Formula : y = ab^x

Where a is the initial value

b = growth rate

x = hours

So, A formula to represent how many bacteria strands are present at the nth hour : $f(n)=3(2)^n$

Now we are supposed to find how many strands of bacteria are present at 4 hours.

Substitute the value in the formula :

$f(4)=3(2)^{4}$

f(4)=48

Hence 48 strands of bacteria are present at 4 hours.

Vlad [161]

Answer:

√x

Step-by-step explanation:

The given expression

1/x^-3/6

Can be written as

1/x^-1/2

Use the negative exponent rule

1/x^n = x^n

Using the rule from above above

1 * x^-1/2

1 * √x =

√x
