Ugo [173]

Answer:

$1.8*10^{-10}$

Step-by-step explanation:

To find the number in scientific notation you want to find how many times you have to move the decimal to get the decimal to be right after the first non-zero number. If you move to the left the exponent is positive and if you move it to the right the exponent is negative. The answer would be $1.8*10^{-10}$ .

Let f(x,y)=x²-3xy-y² Compute f(5,0) and f(5,-3).

cupoosta [38]

Answer:

f(5, 0) = 25

f(5, -3) = 61

Step-by-step explanation:

f(x, y) = x² - 3xy - y²

⇒ f(5, 0) = (5)² - 3(5)(0) - (0)²

= 25 - 0 - 0

= 25

⇒ f(5, -3) = (5)² - 3(5)(-3) - (-3)²

= 25 - 15(-3) - 9

= 25 + 45 - 9

= 61
