Answer:
45. (8√2)∠π/4
46. (7√2)∠3π/4
Step-by-step explanation:
The polar form of a+bi is ...
a +bi ⇔ (√(a²+b²))∠arctan(b/a)
__
45. 8 +8i = (√(8² +8²))∠arctan(8/8) = (8√2)∠π/4
__
46. -7 +7i = (√((-7)² +7²))∠arctan(7/-7) = (7√2)∠3π/4
_____
Additional comment
The arctan function usually returns a value in the range -π/2 to π/2. The quadrant of the desired result can be determined by the signs of the components of the vector. For negative real parts, π needs to be added to the value that is usually returned by the arctan function.
What is the volume of one rubber ball? Round to the nearest hundredth of a centimeter.
Answer:
The volume of one rubber ball is 20.58 cubic centimeters.
Step-by-step explanation:
The rubber ball has a spheric format.
A sphere with radius r has volume given by the following equation:
In this question:
r = 1.7 cm.
The radius is in centimeters, so the volume will be in cubic centimeters.

3) $0.41
Step-by-step explanation:
Answer: 9 houses
Step-by-step explanation:
Step 1:
Since 2/3 of the houses were sold last month, 1/3 of them were left.
45 * 1/3 = 15 houses left last month
Step 2:
Since 2/5 of the remaining houses were sold this month, 3/5 of them were left
15 * 3/5 = 9 houses left to be sold
there's your answer hope this helps :)

The image of the parabolic lens crosses the x axis at the points
(-8, 0) and (4, 0)
To find the points where the graph of the function crosses the x axis we need to find the values of x that make f(x) equal to zero
hence we have that
f(x) = 1/4 (x + 8) (x - 4)
0 = 1/4 (x + 8) (x - 4)
x + 8 = 0
x = -8
OR
x - 4 = 0
x = 4
hence we can say that the image of the parabolic lens crosses the x axis at the points (-8, 0) and (4, 0)
