Consider the long division problem below. What error did Sam make when he computed the answer?


0.043 StartLongDivisionSymbol negative 0.2709 EndLongDivisionSymbol minus 258 = 129. 129 minus 129 = a remainder of 0 and quotient of negative 63.

The answer should be Negative 6.3. Sam should have moved the decimal point 3 places to the right in both the divisor and the dividend.

The answer should be Negative 630. Sam should have moved the decimal point 5 places to the right in both the divisor and the dividend.

The answer should be Negative 65. Sam made an error subtracting 258 from 270.

The answer should be Negative 61. Sam made an error when multiplying 6 times the divisor

Answer:

he made the error in step 2

A college student is looking for a data plan for her cell phone. She has found an option that offers a 2 gigabyte monthly allowance for data.

The monthly cost of this plan can be represented by function C, defined by:

C(x) = 30x + 5, where x is the gigabyte of data used over the monthly allowance.

Find C(0.7)

Select the correct answer as well as the correct explanation for the situation.
Group of answer choices
A. C(0.7)= 26 This means the plan costs $26 a month.
B.vC(0.7)= 26 This means that the cost would be $26 if she uses 0.7 gigabytes over the 2 gigabytes allowance in a month.
C. C(0.7) = 50 This means that the cost would be $50 if she goes over the 2 gigabytes monthly allowance.

Find the range of the function
g(x) = -3x2 + 4 given the domain {-3, -2, 0, 1}
