Answer:
y = 218
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers present)
27 = (20 + 2y + 25 + y + 30)/27
27 = (3y + 75)/27
3y + 75 = 729
3y = 729 - 75
3y = 654
y = 218
Given the equation:
![r=3-5\cos \theta](https://tex.z-dn.net/?f=r%3D3-5%5Ccos%20%5Ctheta)
Let's identify the type of polar graph for the equation.
To identify the type of polar graph, use the formula below to get the Cartesian form:
![(x^2_{}+y^2)=r(\cos \theta,\sin \theta)](https://tex.z-dn.net/?f=%28x%5E2_%7B%7D%2By%5E2%29%3Dr%28%5Ccos%20%5Ctheta%2C%5Csin%20%5Ctheta%29)
Thus, we have:
![(x^2+y^2)=3\sqrt[]{x^2+y^2}-5x](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%3D3%5Csqrt%5B%5D%7Bx%5E2%2By%5E2%7D-5x)
We have the graph of the equation below:
We can see the graph forms a Limacon with an inner loop.
Therefore, the type of polar graph for the given equation is a limacon with inner loop.
ANSWER:
Answer:
(0,4)
Step-by-step explanation:
Here, we want to find the y-intercept of the quadratic function
g(x) = 5x^2 + 9x + 4
Mathematically, we know that the y-intercept is the position on the graph where we have x = 0
so, to find the y-intercept value, we have to find g(0)
simply put, we have to substitute the value of 0 for x
Mathematically, we have this as;
g(0) = 5(0)^2 + 9(0) + 4
g(0) = 0 + 0 + 4
g(0) = 4
thus, we have the y-intercept point as (0,4)
I believe the answer is 12 feet because 12 feet is the longest dimension
