Answer:

The answer to your question is:

Step-by-step explanation:

x² + 3x - 5

x² + 3x + (3/2)² = 5 + (3/2)²

(x + 3/2)² = 5 + 9/4

(x + 3/2)² = (20 + 9) /4

(x + 3/2)² = 29/4

x + 3/2 = ±√29 / 2

x 1 = -3/2 + √29/2 x2 = -3/2 - √29/2

x1 = 1.19 x2 = -4.19

The population of the town was 25,000 people.Then 3,200 people moved away.What was the percent of increase?

german

Answer:

-12.8%

Step-by-step explanation:

To calculate the percent decrease, we:

Find the difference between the new value and the original
Divide the number by the original
Multiply by 100 and the % symbol.

The population of the town originally had 25,000. 3,200 people moved away. This means that the new population is 21,800.

21,800-25,000=-3,200
-3,200/25,000=-0.128
-0.128(100)=-12.8%

The towns population decreased by 12.8%.

maria [59]

Answer:

$\frac{23}{3}$ cubic units

Step-by-step explanation:

To find the volume, we can multiply the base by the height. $\frac{4}{3}$ * $\frac{23}{4}$ is $\frac{92}{12}$ , or $\frac{23}{3}$ . So the volume is $\frac{23}{3}$ cubic units.
