Step-by-step explanation:

450 - 396 = 54

(54/450) * 100% = 12%

Hence the decrease is 12%.

Answer:

<h2>12%</h2>

Step-by-step explanation:

The way to solve is to divide the number.

396/450 = 0.88 or 88%

Now, we subtract 88 from 100 to get 12, since we wanted the percent decrease.

Simplify (5.1)(5.12)4.<br><br> (5.1)6<br> (5.1)7<br> (5.1)8<br> (5.1)9
Andru [333]

The simplified expression of (5.1)(5.1^2)^4 is (5.1)^9

<h3>How to simplify the expression?</h3>

The expression is given as:

(5.1)(5.12)4

Rewrite the expression properly as follows:

(5.1)(5.1^2)^4

Rewrite the expression properly as follows:

(5.1)(5.1^2)^4 = (5.1) * (5.1^2)^4

Apply the power law of indices

(5.1)(5.1^2)^4 = (5.1) * (5.1^8)

Apply the power law of indices

(5.1)(5.1^2)^4 = (5.1)^(1 + 8)

Evaluate the sum

(5.1)(5.1^2)^4 = (5.1)^9

Hence, the simplified expression of (5.1)(5.1^2)^4 is (5.1)^9

E^2x -2e^x -24=0 please answer fast
serg [7]

Answer:

x = ln6

Step-by-step explanation:

e^2x - 2e^x - 24 = 0

a = e^x

=> a^2 - 2a - 24 = 0

=> (a + 4)(a - 6) = 0

=> a = -4 => e^x = -4 (invalid because e^x > 0)

=> a = 6 => e^x = 6 => x = ln6
