Answer:

x=5/2, y=0 & x=5, y=5. So the answer is C).

Step-by-step explanation:

2x^2-13x+20=2x-5

2x^2-13x-2x+20-(-5)=0

2x^2-15x+20+5=0

2x^2-15x+25=0

factor out the trinomial

(2x-5)(x-5)=0

zero property

2x-5=0, x-5=0

2x=0+5=5, 2x=5, x=5/2

x=0+5=5

y=2(5/2)-5=5-5=0

y=2(5)-5=10-5=5

What is the diameter of a sphere with volume of 7483

elena-14-01-66 [18.8K]

Answer:

The diameter of the sphere with the given volume is 24.268 units

Step-by-step explanation:

Volume of a sphere is given by the equation:

$V=4/3\pi r^3$

Plug in your volume and solve for r

$7483=4/3\pi r^3$

$7483(3/4)=\pi r^3$

$5612.25=\pi r^3$

$5612.25/\pi =r^3$

$1786.43=r^3$

$\sqrt[3]{1786.43}=r$

$r = 12.134$ units

$d = 2r$

$d = 2(12.134)$

$d = 24.268$ units
