Answer:
the simplified form is 3/5
Step-by-step explanation:
1 meter = 3.28 ft
A = L * l = 2 * 3 = 6 square meter
To tranform it into square feet: 6 * 3.28 = 19.68 sq ft
Y= -2 - (the square root of) 21 and Y= -2+ (the square root of) 21
Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
I agree the answer is 225 and you can also use the calculator too.
