An architect plans to buy 8 stone spheres and 5 stone cylinders. For the same​ amount, can buy 3 stone spheres and 9 stone cylinders. If one stone cylinder costs ​$43.47​, how much does each stone sphere​ cost?

1010: 3030

is it i think

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

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)

the correct answer is c

good luck love
