<em>Assuming the pattern continues...</em>

Answer:

$128$

Step-by-step explanation:

We see that this is a geometric series with common ratio $-2$ .

So, the 6th term is the 4th term times $(-2)^2=2^2=4$ .

So, the answer is $4(-32)=\boxed{128}$ and we're done!

Note:

The closed form for this geometric series is $4*(-2)^{n-1}$ , which means the nth term is always $4*(-2)^{n-1}$ .

A container contains water at temperature 80 degree celcius. After every 10 minutes, the change in temperature is - 4 degree cel

lilavasa [31]

For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: final temperature
We write then the equation that models the problem:
$y = (-4/10) x + 80
$
For y = 20 we have:
$20 = (-4/10) x + 80
$
Clearing x:
$(4/10) x = 80 - 20

x = (10/4) * 60

x = 150$
Answer:
The temperature of the water will be 20 degree celcius after 150 minutes

Snezhnost [94]

Answer:

A) ≈ 6.93

B) ≈ 0.02

Step-by-step explanation:

Formula : a² + b² = c²

2.4² + 6.5² = c²

5.76 + 42.25 = c²

c = √48.01

c ≈ 6.93

Formula = c² - a² = b²

1/3² - 1/4² = b²

1/9 - 1/16 = b²

b = √7/144

b ≈ 0.02
