TEA [102]2 years ago
6 0

Answer:

8.6 meters

Step-by-step explanation:

a² + b² = c²    means        leg² + leg² = hypotenuse ²

5² + 7² = hypotenuse²

25 + 49 = hypotenuse²

74 = hypotenuse ²

\sqrt{74} = hypotenuse

8.6 = hypotenuse

The temperature of a cup of coffee varies according to Newton's Law of Cooling: dT dt equals negative k times the quantity T min
denis23 [38]

Answer:

  (b)  67

Step-by-step explanation:

A solution to the differential equation describing the temperature according to Newton's Law of Cooling could be written as ...

  T = (final temp) + (initial difference)×(decay factor)^t

where the decay factor is the fraction of change during 1 unit of time period t.

__

Here, the initial difference of 100-25 = 75 degrees decays to 90-25 = 65 degrees in 1 minute. So, the units of t are minutes, the decay factor is 65/75, the initial difference is 75 degrees, and the final temperature is 25 degrees. That lets us write the equation as ...

  T = 25 +75(65/75)^t

Then for t=4, the temperature is ...

  T = 25 +75(13/15)^4 ≈ 67.3 . . . . degrees

After 4 minutes the temperature of the coffee is about 67 degrees.

Negative 1X minus 4X equals -4 minus 4X +4+5
Bond [772]

Answer:

X = - 5

Step-by-step explanation:

The above word problem is mathematically interpreted thus:

-1X - 4X = -4 - 4X + 4 + 5

-5X = - 4 - 4X + 4 + 5

-5X = - 4 - 4X + 9

Collect like terms

-5X + 4X = - 4+ 9

-X = 5

X = - 5
