The Halloran Family has purchased a cell phone plan for the five members of the family. The plan is for 20 gigabytes
Black_prince [1.1K]

The amount of  money by which  Denny went over is $45

By how many gigabytes did the family exceed their data usage?

The initial plan was for  20 gigabytes, eventually, the family used 24.5 gigabytes in the month, which means the excess amount of data used can be determined thus:

excess data usage=24.5 gigabytes-20 gigabytes

excess data usage=4.5 gigabytes

For each extra gigabyte of data, the family needs to pay $10, which means that the amount of money Denny owes is 4.5 gigabytes multiplied by $10

The amount that he went over=$10*4.5

the amount that he went over=$45

Write g(x) = 4x2 + 88x in vertex form. The function written in vertex form is g(x) = ___ (x +11)2 +____.
wel

The\ vertex\ form:\\\\f(x)=a(x-h)^2+k

\text{Use}\ (a+b)^2=a^2+2ab+b^2\qquad(*)

g(x)=4x^2+88x=4(x^2+22x)=4(x^2+2\cdot x\cdot11)\\\\=4(\underbrace{x^2+2\cdot x\cdot11+11^2}_{(*)}-11^2)=4[(x+11)^2-121]=4(x+11)^2+(4)(-121)=4(x+11)^2-484
