The following sequence shown up top is arithmetic sequence
Answer:
80.029
Step-by-step explanation:
(8)(10)+2+1/100+9(1/1000)
=80+2+1/100+9(1/1000)
=80+201/100+9(1/1000)
=8201/100+9(1/1000)
=8201/100+9/1000
=82019/1000
The side that measures 12 cm corresponds to the side that measures 3 cm.
The side that measures 16 cm corresponds to the side that measures 4 cm.
The ratio of the side lengths is (12 cm)/(3 cm) = (16 cm)/(4 cm) = 4
Now let's calculate the two areas.
For the 3 cm by 4 cm rectangle:
A = LW = 3 cm * 4 cm = 12 cm^2
For the 12 cm by 16 cm rectangle:
A = LW = 12 cm * 16 cm = 192 cm^2
The ratio of the areas is (192 cm^2)/(12 cm^2) = 16
The ratio of the areas is 16.
The ratio of side lengths is 4.
Notice that 16 = 4^2.
The ratio of the areas is the square of the ratio of the side lengths.
9x^2-49
It equals:
(3x+7)(3x−7)
Hope this helps!
Step-by-step explanation:
a)
<u>The first laptop</u>
- Initial value- $2000
- Value loss - 14% every year
- Function for value- V(t) = 2000*0.86^t
<u>The second laptop</u>
- Initial value- $1200
- Value loss - 11% every year
- Function- V(t) = 1200*0.89^t
b)
Monthly percent decrease
<u>The first laptop:</u>
<u>The second laptop:</u>
c)
The second laptop will lose less value in 5 years hence is better choice
