Answer:
a
Step-by-step explanation:
Given
u = (x₁, y₁, z₁ ) and v = (x₂, y₂, z₂ ) then the dot product is
u • v = (x₁ x₂ ) + (y₁ y₂ ) + (z₁ z₂ )
Then
v • w
= (5 × 9) + (- 4 × - 2) + (4 × 7)
= 45 + 8 + 28
= 81 → a
Exact Form: t = 8/5
Decimal Form: t = 1.6
Mixed Number Form: t = 1 3/5 (one and three fifths)
A full circle is 360 deg.
A full circle is 2 pi radians.
That gives us a conversion equation:
2 pi radians = 360 deg
which can be reduced to
pi radians = 180 deg
Divide both sides by pi radians to get
1 = (180 deg)(pi radians)
Now we can convert:
11 pi/4 radians * (180 deg)/(pi radians) = 11/4 * 180 deg = 495 deg
Answer:
The painting is
Step-by-step explanation:
From the question we are told that
The amount of carbon present after t year is
{Note ; This is the function }
Here is the amount of carbon-14 after time t
the original amount of carbon-14
Now given that the paint as at now contain 27% of the original carbon-14
Then it mean that
So the equation is represented as
