Answer:
The principal is $2400
Step-by-step explanation:
Given
Required
The principal amount
The principal amount is the amount invested.
From the question, we understand that $24000 was invested.
Hence, the principal is $24000
Answer:
Step-by-step explanation:
Given a vector < x, y > then its magnitude is
Given the directed line segment
P (0, 0 ) → Q (3, 2 ) then
PQ = q - p = (3, 2 ) - (0, 0 ) = < 3 - 0, 2 - 0 > = < 3 , 2 >
| PQ | = 
= 
=
Answer:
A and B
Step-by-step explanation:
Now I won't really get into how the rest works but I do know that if you multiply A and B together, 4x2 is 8, which matches with the expression in number 3. It cant be A and C, because that would lead to 4, and A and D, because that would be an expression with 6, which doesnt match the expression in 3.
We apply arrhenius equation to solve this problem which relates Kc to the change in temperature and that <span>ΔH° is the constant. The arrhenius eqn is :
ln (Kc2)/ ln (Kc1) = </span><span>ΔH°/R * [(1/T1)- (1/T2)] where T is in kelvin.
Thus,
</span>ln (0.575)/ ln (0.405) = <span>ΔH°/8.314 * [(1/(40+273)- (1/(90+273)]
</span><span>ΔH° = 11566.81 J/mol</span>
Function A has only one x-intercept
