Answer:
8.0
Step-by-step explanation:
Using the SOH CAH TOA identity
cos theta = adjacent/hypotenuse
cos 37 = x/10
x = 10cos 37
x = 7.99
The vale to the nearest tenth is 8.0
Answer this pic please and explain how to do it
1 answer:
Balancing of equations as shown in the attached document requires that the number of atoms, of an element, on the left of the equation is equivalent to the number of the atoms of the same element on the right of the equation. This is in observation of the conservation of mass rule of thermodynamics. Mass and energy cannot be destroyed nor created, it can only be transformed from one form to another. In this case, mass remains the same in the system since this is a chemical reaction- only the bonds between atoms are being rearranged.

Answer:
Step-by-step explanation:
Given that one of the zeroes is 1 - i.
Complex roots occur in pairs.
This means, if a + bi is a zero of a polynomial, then a - bi is also its zero.
Therefore, 1 + i is also a zero of the polynomial.
Factors are <em>x</em> - (1 - i) and <em>x</em> - (1 + i).
Multiply the factors.
[<em>x</em> - (1 - i)][<em>x</em> - (1 + i)] = (<em>x</em> - 1 + i)(<em>x</em> - 1 - i)
Given that one of the zeroes is .
Irrational roots occur in pairs.
This means, if an irrational number <em>m </em>is a zero of a polynomial, then - <em>m</em> is also its zero.
Therefore, is also a zero of the polynomial.
Factors are and
.
Multiply the factors.
Hence, the required polynomial is .
