Answer:
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given y = cos² (x² + x³) ....(i)
By using differentiation formulas
a)
b)
<u><em>Step(ii):-</em></u>
Differentiating equation (i) with respective to 'x'
<em>First apply formula </em><em></em>
<em>Now we will apply formula </em>
<em>Again apply formula </em><em></em>
we know that trigonometric formulas
Sin 2θ = 2 sinθ cosθ
<u><em>Final answer:-</em></u>
The pyrite cube is, well, a cube, so it has a side length <em>s</em> such that the area of its base is
<em>s</em> ² = 5.76 cm²
which means
<em>s</em> = √(5.76 cm²) = 2.4 cm
Then its volume is
<em>s</em> ³ = 13.824 cm³
Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of
(€785/cm³) × 13.824 cm³ = €10,851.80
Answer:
they made 5 pies
Step-by-step explanation:
total sold = 40
3 pies from the cafeteria times 5 cut pieces = 15
40 - 15 = 25
25 / 5 = 5
the expression is 5x + 15 = 40
5 is how many slices were cut
15 is the slices from the 3 from the cafeteria
40 is how many were sold
5 is how many were made
Answer:
<u>90 - ( -4 )</u> and <u>90 + 4</u>
Step-by-step explanation:
I got it correct on the test :)
Answer:
Well, the answer to 17 divided by 2635 is 155, however, the number in the box must be 850, I believe.
935 subtracted by 850 equals 85 divided by 17 equals 0.
I hope this was helpful!
