Zaiden is an american traveling with a tour group in southeast asia. during a stop in the philippines, he purchases a souvenir that is priced at 2,621 philippine pesos using his credit card. if the exchange rate that day is usd to php = 43.36, which is the best estimate of the charge zaiden will later find on his credit card statement?

Zaiden would later find $60.45 on his credit card statement.

Step-by-step explanation:

When Zaiden purchased a souvenir, exchange rate of dollar to PHP  was

1 USD = 43.46 PHP

Cost of Souvenir = 2,621 PHP

Charge in USD = 2,621 ÷ 43.36 = $60.45

Zaiden would later find $60.45 on his credit card statement.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
