Answer:
Step-by-step explanation:
Standard equation of an ellipse,
(h, k) is the center of the ellipse
Value of a = Distance of the center from the vertex
b = Distance of the center from the covertex
From the picture attached,
a = Distance of the center (h, k) from the vertex (2, -2) = 3 units
b = Distance of the center (h, k) from the co-vertex (-1, 0) = 1 unit
Center of the ellipse (h, k) = (-1, -2)
Answer:
X = 10.7
Step-by-step explanation:
25^2 - 16^2 = 369 which squared is approximately 19.2. We need X which is the smaller side so we minus 22^2 from 19.2^2 which is 115.36 which is squared to 10.7
Answer:
Miley can walk a distance of 
miles in four hours.
Step-by-step explanation:
Given that:
Distance walked by Miley in 
hours = 
miles
We will find unit rate in term of hours.
Multiplying both sides by 3/5
Distance walked in four hours = 
Distance walked in 4 hours = 
Hence,
Miley can walk a distance of miles in four hours.
Answer: 8 hour
Step-by-step explanation:
Answer: x(-1.8-6y) = -1.8*x -6*y*x
Step-by-step explanation:
The distributive property says that if we have:
A*(B + C) where A, B and C can be any numbers, we can expand the equation as:
A*(B + C) = A*B + A*C.
So, in this case, we have the equation:
x*(-1.8 - 6y)
so we can expand this as:
x*(-1.8 - 6y) = x*(-1.8) + x*(-6*y) = -1.8*x -6*y*x
