Answer:
7.83
Step-by-step explanation:
You know the sine of an angle in a right triangle is the ratio of the opposite side to the hypotenuse:
Sin = Opposite/Hypotenuse
sin(50°) = BC/BA = 6/?
? = 6/sin(60°) ≈ 7.83 . . . . units
AB ≈ 7.83 units
Answer:
Step-by-step explanation:
If the polynomial function has zeros at 9 with multiplicity 1, then 
is a factor of the polynomial.
Also if the polynomial function has a zero at 
with a multiplicity of 2, then
is another factor of the polynomial.
The polynomial function can therefore be written as;
But the given polynomial has an 
value of 2, hence the required polynomial is
Answer:
1.) is 78 2.) is 4
Step-by-step explanation:
We begin with 100 mL of the 2% saline solution, and will add x mL of the 0.5% saline solution. The total volume of the mixture will be (100 + x) mL. The total mass of salt will be:
(100)(2%) + (x)(0.5%) = 2 + 0.005x
This would have to be 0.79% of the total volume:
(100+x)(0.79%) = 0.79 + 0.0079x
Equating:
x = 417.24 mL
