Answer:
15
Step-by-step explanation:
In the first position we have 10 possible numbers, and the same for the 2nd and 3rd positions becuase the numbers are replaced, so our answer is because of the multiplication rule.
Answer:
129 m/s^2
Step-by-step explanation:
The length of a rectangle is increasing at a rate of 9m/s
dL/dt = 9m/s
The width is increasing at a rate of 7m/s
dw/dt= 7m/s
The formular for solving the area of a rectangle is length × width
Therefore, to calculate how fast the rectangle is increasing we will apply the product rule
dA/dt= L × dw/dt + W × dl/dt
= 12×7 + 5×9
= 84+45
= 129m/s^2
Hence the area of the rectangle is increasing at 129m/s^2
36.
You can get this by taking half of the middle term and squaring it.
$2.6, multiply 13 by .2 and you get 2.6
