The answer is The second one because I took this test before and I got it right
Answer:
if the equation is f(x)=ax^2+bx+c
Step-by-step explanation:
other leg = 12 cm
using Pythagoras' identity with x as the side to be found, then
x = √(13² - 5² ) = √(169 - 25 ) =√144 = 12
So 10 questions is 100% you missed 30% of the questions so you would do 100%-30% which is 70%
To get a fraction to a decimal, you divide the top number by the bottom number. So, in this case it would be 8 divided by 125. Gives you 0.064.
