Round off 80.6 to the nearest whole number

1 answer:

4 0

It would be 81 because in decimals the whole number is before the decimal point and since 6 is greater than 4 (1 through 4 round down and 5 through 9 round up)you would round up the 80 to make it 81

If an arrow is shot upward on Mars with a speed of 68 m/s, its height in meters t seconds later is given by

Talja [164]

Answer:

(a) dy/dt = 68 - 3.72t

(b) 64.28m/s

Step-by-step explanation:

Given y = 68t - 1.86t²

Average Speed is rate of chance of distance with respect to time. Written as dy/dt

To obtain dy/dt, we differentiate y with respect to t, doing that, we have

dy/dt = 68 - 2(1.86)t

= 68 - 3.72t

(a) dy/dt = 68 - 3.72t

(b) To estimate the speed when t = 1, we substitute t = 1 in dy/dt .

dy/dt at t = 1 is

68 - 3.72(1)

= 68 - 3.72

= 64.28

The speed at t = 1 is 64.28m/s

Rewrite the following radical expression in rational exponent form. (√x)5

ch4aika [34]

If you meant:
$( \sqrt{x})^5$

Then, let's change the square to read:
$(x^ \frac{1}{2})^5$

Now, we can just multiply the two powers, and your answer is:
$x^ \frac{5}{2}$

Hope I helped.
