PLS PLS HELP!! Sandy has $4,500 to invest. She can choose to put the money in Bank “A” that pays 5% interest per year compounded semi-annually (twice per year) or she can choose. Bank “B” that pays 4.8% interest per year compounded continuously.
After ten years,
a) how much money would sandy have if she puts all her money in Bank “A” Round down to the nearest 0.01 $

b) how much money would Sandy have if she puts all her money in Bank “B” Round down to the nearest 0.01
$

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

it would be 6xy and -16xy.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
