Integrated Math 1 semester review

The value of a painting is $12,000 in 1990 and increases by 8% of its value each year.  Write and evaluate an expression to estimate the paintings value in 2005.

• 1.08(12,000)^t = $36,000
• 12,000(1.08)^t = $38, 066
• 12,000(0.5)^t = $10,000
• 12,000(0.92)^t = $40,000

What is the common ratio for the sequence:
28, 14, 7, 3.5...
Reminder: common ratio is common multiple used to get  the next output

Write in slope intercept form (y=mx+b)
5x - 3y = -9

• y = (5/3)x - 3
• y = (5/3)x + 9
• y = (5/3)x + 3
• y = (3/5)x + 3

Write a rule:  A plumber charges $50 for a house call plus $12 per hour for labor.

• y = 50x + 12
• y = 50 + 12x
• y = 62x
• x = 50 + 12y

If you have an arithmetic sequence: find the missing numbers 6, _____,______,______,226

• 56, 107,159,226

• 43, 80,118,226

• 61, 116,171,226

• 18,54,162 226

If you have a geometric sequence find the missing numbers: 4, ___,____,____,9604

• 2404,4804, 7204,9604

• 36, 324,2916,9604

• 32,256,2048,9604

• 28,196,1372,9604

What do you know about this : y= 6(1/2)^x

• It is arithmetic, f(0) = 6 and 1/2 is the common difference

• It is geometric, f(1)=6 common ratio is 1/2 and it is a straight line

• It is geometric, f(0)=6 common ratio is 1/2 the graph is a curve

• It is arithmetic, f(0)=6, common difference is 1/2 and it is a curve
