An infinite geometric series has a first term a1=15 and a sum of 45. Explain how you can use the formula S=a1/1-r to find the value of the common ratio. What is the value of r?

she will travel a distance in the range of 3 - 11 miles

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
