What are the solutions of the equation x4 – 9x2 + 8 = 0? Use u substitution to solve.

rosijanka [135]

Answer:

Option (2)

Step-by-step explanation:

Given equation is,

x⁴- 9x² + 8 = 0

Let x² = t

By substituting the value of x²= t in the equation,

t² - 9t + 8 = 0

t² - 8t - t + 8 = 0

t(t - 8) - 1(t - 8) = 0

(t - 1)(t - 8) = 0

(t - 1) = 0 ⇒ t = 1

(t - 8) = 0 ⇒ t = 8

Since, t = x²

x² = 1 ⇒ x = ±1

x² = 8 ⇒ x = ±2√2

Therefore, Option (2) will be the correct option.

Cody increased the amount of money he saves each week from $40 to $75. By

Natali [406]

Answer:

So Cody increase his savings by 87.5%

Step-by-step explanation:

We are given Cody's original savings = $40

We are given his new savings total = $75

Now, in order to find out the percentage we have to first find out by how much did he increase his savings:

Increase in savings = $75 - $40 = $35

So now we have the increase in savings we can find out the percentage:

$increase(\%) \: = \frac{increase \: in \: savings}{original \: savings} \times 100$

Now we plug in our values that we found:

$increase(\%) = \frac{35}{40} \times 100\\ increase(\%) = 87.5\%$

So Cody increase his savings by 87.5%
