Step-by-step explanation:
Area of the circle = pi×r²
= 22/7 × 6 × 6
= 113.14 unit²
To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used:
r = sqrt( x^2 + y^2)
<span>θ = tan^-1 (y/x)
</span>
Substituting (-3,3) accordingly to the equations, we obtain r equal to 3*sqrt(2) and θ equal to -π/4. Thus, the polar coordinates equivalent to (-3,3) is (3*sqrt(2), -π/4).
Answer:
(1,-2) and (0,-5) (There are an infinite amount more)
Step-by-step explanation:
The easiest way to find solutions is to plug in an x value. Let's try 1:
y = 3(1) - 5⇒y = 3 - 5⇒y = -2
(1,-2)
Let's try 0:
y = 3(0) - 5⇒y = 0 - 5 ⇒y = -5
(0,-5)
64, because its square root is 8.
49, because its square root is 7.
144, because its square root is 12.
4, because its square root is 2.
Answer: X=14
Step-by-step explanation:
The leg and hypothesis is the sum of 20. You already have 6. 6 from 20 is 14
