The answer would be 40.
Do 69-9 which gives you 60. And then 2/3 / 60 (divide 60 by 3) and you get 20. 20*2=40

Find K' if the figure is reflected across the x-axis
snow_lady [41]
<h3>Answer:  K ' is at (1, 4)</h3>

Explanation:

Point K is located at (1, -4)

We use the rule that (x,y) \to (x,-y) when reflecting over the x axis.

The x coordinate stays the same, but the y coordinate flips from positive to negative or vice versa.

Therefore, K(1,-4) will move to K ' (1, 4)

A profit of a football club after a takeover is modeled by p(t) = t3 - 14t2 + 20t + 120, which t is the number of years after th
Bogdan [553]
T = 5, so after 5 years
p(t) = t^3 - 14t^2 + 20t + 120

Take derivative to find minimum:
p’(t) = 3t^2 - 28t + 10

Factor to solve for t:
p’(t) = (3t - 2)(t - 5)
0 = (3t - 2)(t - 5)

0 = 3t - 2
2 = 3t
2/3 = t

Plug 2/3 into original equation, this is a maximum. We want the minimum:

0 = t - 5
5 = t

Plug back into original:
5^3 - 14(5)^2 + 20(5) + 120
125 - 14(25) + 100 + 120
125 - 350 + 220
- 225 + 220
p(5) = -5

Helen [10]

Answer: 12 miles

Step-by-step explanation:

From the question, we are informed that Marie walk 680 miles to the south pole and that the trip took 58 days and they travel the same distance each day.

The number of miles that they travel each day to the nearest whole number will be gotten by dividing 680 miles by 58. This will be:

= 680 miles / 58

= 11.72

= 12 miles to nearest whole number.
