Answer:
first one and the biology one
Step-by-step explanation:
You have this rule, if there is < 30° then value of y is
y=12✓3:2
y=6√3
And Pitagora's theorem:
c²=a²+b²
In this case:
(12√3)²=y²+x²
Then x is:
x²= (12√3)²-y²
x²= (12√3)²-(6√3)²
x²=432- 108
x²= 324
x=✓324
x=18cm
32.45 is most precise . Precise means how many points after decimal is reached. Accurate means how close your measurement of a value is that to the true value. Eg :Say 35cm is the measure of length of a body and a person got the measurement to be 34 . Another person2 got the measurement to be 32.88 . So in this case the first person has an accurate answer as he is close to the true value 35 , but person2 is more precise as he has two decimal places.
Answer: (x, y) —> (-x, y)
Step-by-step explanation:
This is because the translation rule for reflection across the y-axis is (x, y) —> (-x, y)
5 times 3 equals 15 so they gained 15 yards. 12 times 2 equals 24. 24 minis 15 equals 9. So the answer in 9 yards
