Answer:
The equation of the line is and the equation of the circle is .
Step-by-step explanation:
(a) Given: The given points are and .
To find: The parametric equation of line containing points and .
We know that the parametric equation of line containing and is given by where ∈.
Now,
i.e,
And,
Hence, the required parametric equation of the line is .
(b) Given: The radius of circle is 3 and centre is .
To find: The parametric equation of circle with radius 3 and centre .
We know that parametric equation of circle with radius and centre is given by where and .
So, the parametric equation of circle having radius 3 and centre is .
Hence, the required equation of the circle is .
-14-x
Distribute the negative.
Answer:Meyer uses 2.5 loads
Step-by-step explanation:Why does he use 2.5? Because, he has 8 loads and with 1 load he covers 2/5 of his driveway so 2 loads covers 4/5 and 2.5 loads cover 5/5 of his driveway
y=11.142857
Simplify 5.2/3.5 to 1.485714
1.485714=y/7.5
Multiply both sides by 7.5
1.485714× 7.5=y
Simplify 1.485714×7.5 to 11.142857
11.142857=y
Switch sides
