Answer:

The speed in scientific notation is (1.1)(10^{3}) feet per second.

Step-by-step explanation:

1. You have the following speed: One thousand one houndred feet per second.

2. You must convert from words to number. This is:

1,100 feet per second

3. To express this quantity in scientific notation, you can move the decimal point three places to the left, and write it as: 1.1 by 10^{3} (or 1,000) as following:

1,100=(1.1)(10^{3})

Which absolute value function has a graph that is wider than the parent function, f(x) = |x|, and is translated to the right 2 u
Mariulka [41]
Case 1:  If we multiply f(x) = |x| by a fraction greater than zero and less than 1, the width of the resulting graph will increase.  If the vertex of the original function is moved 2 units to the right, then we'd replace |x| with |x-2|  Only the coefficient (3/4) satisfies the "wider graph" requirement here.

Next time you list answr possibilities, please type them in only one per line, or separate them with commons, semicolons or the like.

The CPI basket price for two consecutive years of five different economies are given. Determine the rate of Inflation for each e
kaheart [24]

Answer:

The inglation rate can be calculated as:

R = ((year2 - year1)/year1 )*100%

A)

Year 1 = $132.00

Year 2 = $134.50

R = (($134.50 - $132.00)/$132.00)*100% = 1.89%

B)

Year 1 = $95.00

Year 2 = $97.50

R = (($97.50 - $95.00 )/$95.00 )*100% = 2.6%

C)

 Year 1 = $100.00

 Year 2 = $102.00

R = (($102.00 - $100.00 )/$100.00 )*100% = 2%

D)

Year 1 = $88.00

Year 2 = $89.25

R = (($89.25 - $88.00 )/$88.00 )*100% = 1.4%

E)

Year 1 = $115.50

Year 2 = $117.50

R = (($117.50 - $115.50 )/$115.50 )*100% = 1.7%

Then the order from least to greatest is:

D, E, A, C, B
