Mathematics

Katarina [22]3 years ago
6 0

Answer:

45

Step-by-step explanation:

Since this is only three terms

Find the three terms and add

j=1   3(1)^2+1 = 3+1 =4

j=2   3(2)^2+1 = 3(4)+1 =13

j=3   3(9)^2+1 = 27+1 =28

The sum is 4+13+28 =45

Sketch feda = 4pie/3 in standard position
rewona [7]
Since 4pi/3 = 3pi/3 + pi/3 = pi + pi/3, that means it goes past the angle of pi (the negative x-axis), and an additional pi/3 radians. So this gives you a diagonal line that passes through the origin, from the third quadrant through to the first quadrant, and makes an angle of 60 degrees with the negative x-axis.

Amiraneli [1.4K]

Answer:

$38.46

Step-by-step explanation:

Minimum payment = 15% of balance

Balance = $256.38

Therefore

15% of $256.38

Change 15% to decimal

15% /100% x $256.38

0.15 x $256.38

$38.46

Her minimum payment is $38.46
