Determine the percentage of the shaded cubes
First, we calculate the number of boxes:
Express as multiplication
This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:
<em>30% were shaded</em>
Answer:
D -$7.20
Step-by-step explanation:
- If she takes (substance) $2.40 every times she forgets to do a chores you have to substance
- but first you have to multiply because she forgets 3 times
- 2.40 × 3 is 7.20
- but since she taking it away it would be negative
so your answer is -$7.20
I hope this helps
Step-by-step explanation:
you can see the steps above
It's hard to type and hard to read the "inverse tangent" function, as you've seen (above).
So, use "arctan x" instead.
Then the problem becomes: "differentiate cos (arctan x)."
You must apply first the rule for differentiating the cosine function, and next apply the rule for differentiating the arctan function:
(d/dx) cos (arctan x) = - sin (arctan x) * [1/(1+x^2)]
