Answer:
Step-by-step explanation:
x=5
y=-5
Hence it lies in 4th quadrant.
x=r cos θ
5=r cos θ ...(1)
y=r sin θ
-5 =r sin θ ... (2)
square and add
(5)²+(-5)²=r²(sin ²θ +cos ²θ )
r²=25+25=50
r=±5√2
dividing
tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)
θ=135°,315°
so polar coordinates are (5√2,315°) and (-5√2,135°)

A rectangular plant holder is 8 inches long 7 1/2 inches wide and 5 inches high. How much potting soil can the planter hold
Answer:
[tex]300[/tex]
Step-by-step explanation:
[tex]8 \times 7 \frac{1}{2} \times 5 \times = 300[/tex]
The rectangular plant can hold the volume of potting soil is 300 cubic inches.
What is a cuboid?A cuboid is a three-dimensional shape in which all sides are rectangles. A cuboid has 6 faces, 8 vertices, and 12 edges. All the angles formed at the vertices of a cuboid are right angles. The opposite edges are parallel to each other.
For the given situation,
The rectangular plant holder is in the shape cuboid.
Length of the rectangular plant,l = 8 inches
Width of the rectangular plant,w = 7 1/2 = 15/2 inches
Height of the rectangular plant,h = 5 inches
The formula of volume of cuboid is
[tex]V=lwh[/tex]
⇒ [tex]V= (8)(\frac{15}{2} )(5)[/tex]
⇒ [tex]V=300[/tex]
Hence we can conclude that the rectangular plant can hold the volume of potting soil is 300 cubic inches.

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
volume = 254.34 cubic inches
Step-by-step explanation:
r = diameter /2 = 6/2 = 3 in
h = 3 × r = 3 × 3 = 9
volume = pi× r^2 × h

A -foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a angle with a short vertical support.
Complete question :
A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.
What is the length x of a diagonal support, to the nearest tenth of a foot?
Answer:
13.80 feets
Step-by-step explanation:
Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :
To obtain x :
Sinθ = opposite / hypotenus
Opposite = 12.5 feets ; hypotenus = x ; θ = 65°
Sin 65 = 12.5 / x
0.9063077 * x = 12.5
x = 12.5 / 0.9063077
x = 13.792225
x = 13.80 feets
