Step-by-step explanation:
problem → 2^x = 4, solve for x
⇒2^x=4
⇒2^x=2^2
⇒x=2
Answer:
z=1.5
Step-by-step explanation:
Simplifying
6z + 3 + -4z = 9
Reorder the terms:
3 + 6z + -4z = 9
Combine like terms: 6z + -4z = 2z
3 + 2z = 9
Solving
3 + 2z = 9
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2z = 9 + -3
Combine like terms: 3 + -3 = 0
0 + 2z = 9 + -3
2z = 9 + -3
Combine like terms: 9 + -3 = 6
2z = 6
Divide each side by '2'.
z = 3
Simplifying
z = 3
Answer:
Choice a: 
Step-by-step explanation:
All you have to do on this one is add the 7 on both sides.
So the answer is anything greater than 5.
Jeremy will pay $41.05 interest.
We know that, Interest = PRT/100
where,
P = principal
R = rate
T = time
For given question, principal (P) = $325.18
interest rate R = 12 5/8%
= 12.625%
And period T = 1 year
We need to find the interest.
⇒ Interest = PRT/100
⇒ Interest = (325.18 × 12.625 × 1) / 100
⇒ Interest = 4105.3975 / 100
⇒ Interest = $41.05
Therefore, Jeremy will pay $41.05 interest.

Answer:
The correct option is (A).
Step-by-step explanation:
The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:
The general growth function can be represented as:
Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>t</em> = time
Com-paring the two functions we get:
This implies that the annual increase rate in number, in billions, of the DNA sequences is 32%.
Thus, the correct option is (A).
