Answer:
if you want to find which lines are parallel you must look at the slopes
Step-by-step explanation:
and you for this you must alone x
1) 3y=-x+5 slope is -⅓
2)3y=x-12 slope is ⅓
3)y=3x-2. slope is 3
4)6y=2x-7 slope is 2/6=⅓.
Finally the answer is 2 and 4 is parallel
Answer:
For a) $A(r(t))=π(4t)^2.$
For b) 803.84
Step-by-step explanation:
For a) we can do a simple substitution on the variable r. Notice that $A=πr^2$ make $A$ a function of $r.$ Then, $A(r(t))=\pi (r(t))^2=\pi (4t)^2.$
For b) you only need to substitute the value $t=4$ on the expresión $A(r(t)).$
Answer:
24
Step-by-step explanation:
To find the range, we subtract the smallest number in the set from the largest number.
The largest number is 66. The smallest number is 42.
66-42=24.
The range is 24.
