Answer: 5 years
Step-by-step explanation:
A= P(1-r)^t
A= Depreciation value
P = Initial amount
r= rate = 7/100= 0.07
t= time
t= (Ln(A/P))/Ln(1-r)
= (Ln(25949.18/37300))/Ln(1-0.07)
t= 4.999 approximately 5 years
Answer:
(D). 6.
Step-by-step explanation:
The number of parts = 1 + 10 = 11.
So 10/11 of the alloy is copper and 1/11 is aluminium.
So the answer is 1/11 * 66
= 66/11= 6 pound,s
Answer:
<em>14 </em>° <em>;</em> <em>83 </em>°
Step-by-step explanation:
( 14x - 1 )° + ( 2x + 2 )° = 97°
14x - 1 + 2x + 2 = 97
16x = 96
x = 6
m∠BCA = ( 2 × 6 + 2 )° = <em>14 </em>°
m∠ABC = ( 14x - 1 )° = <em>83 </em>°
Answer:
The parent function is f(x) = |x|
Step-by-step explanation:
