Hi, I am currently taking the test that has this exact question and I have come to believe the answer to this question is indeed |3.7−(−1.5)|. I hope I helped you.

3.7-(-1.5)

Since the negatives cancel out it would be

3.7+1.5 which equals 5.2°F

Does this help?

Using the recursion equation, it is found that the value of the 2nd iterate is:

x_2 = 3.16228

<h3>What is the recursive equation?</h3>

The value of the nth iteration is given by:

x_n = \frac{x_{n-1} + \frac{10}{x_{n-1}}}{2}

The initial estimate is:

x_0 = 3.1

Hence, the 1st iterate is given by:

x_1 = \frac{x_0 + \frac{10}{x_0}}{2} = \frac{3.1 + \frac{10}{3.1}}{2} = 3.1629

The 2nd iterate is:

x_2 = \frac{x_1 + \frac{10}{x_1}}{2} = \frac{3.1629 + \frac{10}{3.1629}}{2} = 3.16228

Thus, the fourth option is correct.

If y varies directly as x, and y = 25 when x = 5, find y when x = 25.

Because to get from 5 to 25 you need to multiply by 5 so 25 times five equals 125

The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to
Maksim231197 [3]

Considering the given function, we have that:

a) D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.

b) D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.

<h3>What is the function in this problem?</h3>

The distance that the family is from home, after t hours of driving, is given by:

D(t) = 3260 - 55t.

Then, after 12 hours, the distance is given by D(12), that is:

D(12) = 3260 - 55 x 12 = 2600.

D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.

D(t)=2490, hence:

3260 - 55t = 2490

55t = 770

t = 770/55

t = 14

D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.
