First calculate the volume of the rectangular prism, which is base area x height, 2.5x2.5x5 = 31.25 therefore the difference is 35 - 31.25= 3.75 cm3 it should be right
Answer with explanation:
When point (x,y) in two dimensional plane is converted to polar plane,that is in terms of (r,α)
1. Origin (0,0)→Pole
2. x=0,y=0 becomes can be written as→ equation of polar axis,which is equal to 0.
the two curves drawn here has following line of symmetry
1. Symmetry along four lines of blade shaped curve,one along polar axis that is x=0,y=0 and two along,x=y and y=-x.
2. The curve which is in the shape of Cardioid has 1 line of symmetry that is , x=0.
The features which are present in the polar graph
Option:
A. Symmetry about the line
B. Symmetry about the polar axis = 0
The value of x is 8√2.
<u>Step-by-step explanation</u>:
<u>From the right triangle,</u>
- The angles are 90°, 45° and the third angle is unknown.
- Third angle = 180° - (90°+45°) = 45°
- The measure of third angle is 45°
The length of the side opposite to angle 45° is a=8.
Therefore, the value of y opposite to angle 45° is also 8.(b=8)
<u>Using Pythagorean theorem,</u>
The length of hypotenuse is c ⇒ c² = a²+b²
c² = 8²+8²
c² = 64+64 = 128
c = √128
c = √64
2
c = 8√2
Step-by-step explanation:
y = 15× tan25° = 15×0.466 = 6.99 m
r (Hypotenuse) = 15/cos25° = 15/0.906
= 16.56m
the total height = 6.99+16.56 = 23.55 m
