Answer:
Step-by-step explanation:
3000 600
5000 1000
6000 1200
7500 1500
No it doesn't form a proportional relationship because yes, the ratio is constant AFTER the 5,000, you do need to hit the 5,000 first, and then it changes. So no, it's not proportional because it isn't constant throughout the entirety of the relationship. If you're just going based on the table in question, then yes it will be proportional since it doesn't have the 5,000 in it but if you're looking at it in it's entirety, no it's not.
Answer:
$60
Step-by-step explanation:
Movieland is in yellow....at the far left the Moviland- yellow 'regular' price for a DVD is shown as y= $20
three of these would be 3 x $20 = $60

=

Multiply both sides by 3
z + 6 =

Multiply both sides by 4
(4)z + 6 = (3)2z Simplify
4z + 24 = 6z Subtract 4z from both sides
24 = 2z Divide both sides by 2
12 = z Flip the sides to make it easier to read
z = 12
Answer:
Step-by-step explanation:
- Deposit = 800
- Interest rate = 4% compounded quarterly
- Time = 2 years
<u>Number of compounds:</u>
<u>Saving amount at the end of 2 years:</u>
- 800*(1 + 0.04/4)^8 = 866.29
Using cos addition formula:
use x for theta
cos(x+π/6)=cosx*cos(π/6)-sinx*sin(π/6)
sinx=1/4
cosx=√15/4
cos(π/6)=√3/2
sin(π/6)=1/2
cos(x+π/6)=(√15/4*√3/2)-(1/4*1/2)
cos(x+π/6)=(√45/8)-(1/8 )
cos(x+π/6)=(√45-1)/8)
