how is the volume of a solution used in calculating concentration?
Answer:
4/5___0.8___80%
4:5 to 4/5 <--- fraction
100 divided by 5 equals 20 so 20 x 4 = 80% <--- percentage
80% goes to 0.8 <--- decimal
hope i helped
Answer: THE ANSWER IS 2 :)
Step-by-step explanation:
3(q+2) Do distributive property
3q=6 Divide 3q to both side
3q = 3q
q= 2 This is the answer
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them
we know from above that u.v = 120
|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29
so we know:
theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>

Answer:
C. G(x) has no root.
Step-by-step explanation:
A is wrong as the graph shows one minimum.
B is wrong as x approaches negative infinity, F(x) will approach infinity; not negative infinity.
D is wrong as it does not have 4 real roots.
Only answer left is C and it is true that G(x) has no root.
