Answer:
3
Step-by-step explanation:
The square root function (√) only gives positive values, so graphs 1 and 4 make no sense.
When x = -3, the y-value is 0, consistent with graph 3.
D = M/V
D= 21/7
D = 3 g/cm3
Answer:
first one yes

39x+10=180
Answer:
D
Step-by-step explanation:
If
then we can consider right triangle with adjacent leg 4 un. and opposite leg 3 un.. By the Pythagorean theorem,

So,

The key concept you must have to remember is that, the rate is kept constant, as what is specified in the problem. Our basis for the rate is the first situation.
Rate = 20 facts/ 1 min.
Let's equate this to the second situation using x as the time unknown.
20/1 = 35/x
Solving for x,
<em>x = 1.75 minutes</em>
