Place the point of the compass on the intersection of AB and CD and extend the compasses to point R.
Answer:
r = 0.1
Step-by-step explanation:
If (x, y) = (14, 1.4) and the quantities are proportional, the constant of proportionality (r) in ...
y = rx
is ...
r = y/x = 1.4/14 = 0.1
The constant of proportionality is 0.1.
x² - 4x + 8 → there are 3 terms (remember to include the sign with each term)
term 1: x²
term 2: -4x
term 3: 8
Answer:
4A=5.1 per million 4B=3.8 years
Step-by-step explanation:
4A. A=0.2^2+.01t+5.1 the current level would be 5.1
4B. 8=.2t^2+.01+5.1 minus 8 .2t^2+.01-2.9
t=(-1.0+squ.0001-41-.58)/.4
t=(-.01+squ2.3201)/.4
t=3.78 t+3.78=0 =-3.78
t=-3.83 t-3.83=0 =3.83
Answer 3.83 years
Answer:
first option, x < 7
Step-by-step explanation:
- Since the circle is not filled in at 7, that means it doesn't equal 7
hence options 2 and 4 are NOT correct
- Since the arrow is going to the left of 7, all smaller numbers (ex. 6 or 5)
x is less than 7
the third option is incorrect because x is not bigger than 7
