Answer:
72 m
Step-by-step explanation:
Step-by-step explanation:
As the vertex (−2,5) and focus (−2,6) share same abscissa i.e. −2, parabola has axis of symmetry as x=−2 or x+2=0
Hence, equation of parabola is of the type (y−k)=a(x−h)2, where (h,k) is vertex. Its focus then is (h,k+14a)
As vertex is given to be (−2,5), the equation of parabola is
y−5=a(x+2)2
as vertex is (−2,5) and parabola passes through vertex.
and its focus is (−2,5+14a)
Therefore 5+14a=6 or 14a=1 i.e. a=14
and equation of parabola is y−5=14(x+2)2
or 4y−20=(x+2)2=x2+4x+4
or 4y=x2+4x+24

See image below:)
FYI you can use the app photo math, you just take a pic of the problem and it gives you the answer and explains the steps and it is free.
8y = 8
y = 1
x = 8-2y
x = 8-2*1
x = 8-2
x = 6

Answer:
Order from least degree to highest degree
15xy - 89y², 7x³ + 5y, 2x³y + 5x²
Step-by-step explanation:
For polynomials, the degree a polynomial has can be defined as the highest number of power a variable in that polynomial carries.
From the above question, we are asked to arrange this polynomials from least to highest
Hence:
7x³ + 5y , -2x³y + 5x², 15xy - 89y²
Order from least degree to highest degree
15xy - 89y², 7x³ + 5y, 2x³y + 5x²
