What is the value of StartFraction 1.6 times 10 Superscript 14 Baseline Over 3.2 times 10 Superscript 7 Baseline EndFraction in
Helga [31]

Answer:

5.0 times 10 Superscript 6

Step-by-step explanation:

What is the value of StartFraction 1.6 times 10 Superscript 14 Baseline Over 3.2 times 10 Superscript 7 Baseline?

This is represented mathematically as:

1.6 × 10¹⁴/ 3.2 × 10⁷

Solving for this

1.6 × 10¹⁴/ 3.2 × 10⁷

= [1.6/3.2] × 10¹⁴-⁷

= 5 × 10⁶

= 5.0 times 10 Superscript 6

Slope of (0,45) (6,33) (15,15)
Vladimir [108]

Answer:

The slope is -2

Step-by-step explanation:

Given

(x_1,y_1) = (0,45)

(x_2,y_2) = (6,33)

(x_2,y_3) = (15,15)

Required

The slope (m)

Slope is calculated as:

m = \frac{y_2 -y_1}{x_2 - x_1}

So, we have:

m = \frac{33 -45}{6 - 0}

m = \frac{-12}{6}

m =-2

The function f(t)=-16 + 100 models the height of a ball, in feet, dropped from a 100-foot rooftop at time t, in seconds.
Mazyrski [523]

Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

r = \frac{f(b) - f(a)}{b - a}

In this problem, the function is given by:

f(t) = -16t² + 100.

The outputs are given as follows:

  • f(0) = -16(0)² + 100 = 100.
  • f(0) = -16(2)² + 100 = 36.

Hence the average rate of change is given by:

r = (36 - 100)/(2 - 0) = -32 ft/s.

And the correct option is:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

Sun, a kayaker, paddles 8 miles upstream (against the current) in 2 hours. Returning to her original location, she paddles downs
Virty [35]

Answer: a=8 and b=1


Step-by-step explanation:

If x represents the paddling speed, and y represents the speed of the current.

Then Relative speed in upstream =x-y

Relative time in downstream=x-y

When she paddles upstream then distance covered by her=speed\times\ time

⇒8=(x-y)2 or 2(x-y)=8

Thus we get, a=1

When she paddles downstream then distance covered by her=speed\times\ time

⇒8=(x+y)1 or 1(x+y)=8

Thus we get b=1
