Think of compound interest as having interest but doubling the amount.

Answer:
8. C) 24.2
9. A) 8.1
Step-by-step explanation:
8. The radius is shown as being 7.8 +4.3 = 12.1, so the diameter x is ...
d = 2r
x = 2(12.1) = 24.2
__
9. The unknown leg (y) of the right triangle can be found from the Pythagorean theorem.
y² +11.7² = 12.5² . . . . . the radius is half the diameter
y = √(156.25 -136.89) = √19.36 = 4.4
Then the segment of interest is ...
x + y = 12.5
x = 12.5 -4.4 = 8.1
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
1.) (-4,0).....x1 = -4 and y1 = 0
(4,6)......x2 = 4 and y2 = 6
now sub into the formula...
d = sqrt ((4 - (-4)^2 + (6 - 0)^2)
d = sqrt ((4 + 4)^2 + (6^2))
d = sqrt (8^2 + 6^2)
d = sqrt (64 + 36)
d = sqrt 100
d = 10 <=====
u would use the exact same formula for the rest of these problems
2.) (5,7),(0,-5)......distance is : 13
3.) (2,-1),(1,-4).....distance is : 3.16
4.) (-7,-2),(0,7).....distance = 11.4
Answer:
10 + 16c.
Step-by-step explanation:
Collect like terms.
10 + (18c − 2c).
Simplify.
10 + 16c.
Hope this helps!
Have a good day Ma'am/Sir.
