D
to convert from polar to rectangular form use
• cosΘ =
• r² = x² + y²
r = 8 × ( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ← in rectangular form
Answer:
y=2x+3
Step-by-step explanation:
the equation of the line given in y=mx+b form is for m being the slope and b being the y intercept
we are given a point (1,5) and a slope (2)
since we know the slope, we can plug thatk known value into the equation:
y=2x+b
now we need to find b
because the line will pass through the point of (1,5), we can use it to solve for b
substitute 5 as y and 1 as x
5=2(1)+b
5=2+b
3=b
therefore the equation is
y=2x+3

Answer:
32pi - 64
Step-by-step explanation:
The two UNshaded areas are equal to each other. Each one is the
Area (square) - 1/4 Area(circle)
64 - 1/4 (64pi)
64 - 16pi
There are 2 of these unshaded pieces in this question.
Area (square) - 2 (64 - 16pi)
64 - 128 + 32pi
= -64 + 32pi
Area = 32pi - 64
Answer:
30 miles
Step-by-step explanation:
In this context, "per" means "divided by", so to find miles per gallon, divide miles by gallons:
(56 1/4 mi)/(1 7/8 gal) = 30 mi/gal
The vehicle can travel 30 miles per gallon of gas.
_____
My calculator divides mixed numbers directly, as many graphing calculators do. If you're working this out by hand, you can convert to improper fractions, then multiply the numerator by the inverse of the denominator.
(56 1/4)/(1 7/8) = (225/4)/(15/8)
= (225/4)·(8/15) = (225/15)·(8/4)
= 15·2 = 30
