Answer:
200% i think
Step-by-step explanation:
C. 4
Because the rule of the graph is $1.50 per pound of apple, so you have to divide $6.00 by $1.50 and that gives you the answer.

Sin³ x-sin x=cos ² x
we know that:
sin²x + cos²x=1 ⇒cos²x=1-sin²x
Therefore:
sin³x-sin x=1-sin²x
sin³x+sin²x-sin x-1=0
sin³x=z
z³+z²-z-1=0
we divide by Ruffini method:
1 1 -1 -1
1 1 2 1 z=1
-------------------------------------
1 2 1 0
-1 -1 -1 z=-1
--------------------------------------
1 1 0 z=-1
Therefore; the solutions are z=-1 and z=1
The solutions are:
if z=-1, then
sin x=-1 ⇒x= arcsin -1=π+2kπ (180º+360ºK) K∈Z
if z=1, then
sin x=1 ⇒ x=arcsin 1=π/2 + 2kπ (90º+360ºK) k∈Z
π/2 + 2kπ U π+2Kπ=π/2+kπ k∈Z ≈(90º+180ºK)
Answer: π/2 + Kπ or 90º+180ºK K∈Z
Z=...-3,-2,-1,0,1,2,3,4....
Answer:
$7,718
Step-by-step explanation:
Given that :
Cost of car in 2007 = $34000
Cost of car in 2014 = $16200
Predicted value of car in 2021
Lets obtain the percentage Depreciation (d) :
Worth (A) of car in 2014 = $16200
Time (t) = 2014 - 2007 = 7 years
Initial cost (I) = price in 2007
A = I(1 - d/100)^7
16200 = 34000( 1 - d/100)^7
16200 = 34000(1 - 0.01d)^7
(16200/34000)^1/7= 1 - 0.01d
0.8995 = 1 - 0.01d
0.01d = 1 - 0.8995
d = 0.1005 /0.01
d = 10.05
Value of car in year 2021:
t = 2021 - 2007 = 14 years
A = I(1 - 10.05/100)^14
A = 34000(1 - 0.1005)^14
A = 34000(0.8995)^14
A = 34000 * 0.2269950
A =7717.83100
Approximate worth = $7718
