Answer:
Reduced equaton is
.
Step-by-step explanation:
Given parametric equation is,
and 
Now,
substitute in second equation we get,



which is the corresponding rectangular equation after eliinating the parameter.
Now consider,

Of which,
Slope : 
when,






ans so on. Thus sketching th curve will look like given,
Answer:
in steps
Step-by-step explanation:
when slope is negative line goes downwards from left to right
only y = -2x + 20 has slope -2
Here we have first number as positive 43 and the second number is (-35)
so we have to subtract here 43 and (-35)
We will use the following property here:

So that means the two negatives will make positive sign,

On adding 43 and 35 , we will get 78
Answer: +43-(-35)=78
<h3>Answer:</h3>
10 5/8 cups
<h3>Explanation:</h3>
pot amount = 9 × (bowl amount) + (leftover amount)
... = 9 × (1 1/8) + 1/2
... = 9 × (1 + 1/8) + 4/8 . . . . . show 1 1/8 as a sum, rewrite 1/2 to 4/8
... = 9 + 9/8 + 4/8 . . . . . . . . eliminate parentheses using the distributive property
... = 9 + 13/8 . . . . . . . . . . . . add the fractions
... = 9 + 1 5/8 . . . . . . . . . . . convert from improper fraction to mixed number
... = 10 5/8 . . . . . cups . . . add the integer parts
Answer:
210.82
Step-by-step explanation:
arc length= 2pi r (Ø/360)
= 2x 3.14 x 47(257/360)=210.82
