neurons are cells in the nervous system that process and transmit info. An average neuron is about 5 x 10^-6 meter in diameter. A standard table tennis ball is 0.04 meter in diameter. About how many times as great is the diameter of a ball

Ratio = Diameter of ball/Diameter of neuron

Ratio = 0.04 m/5×10⁻⁶ m

Ratio = 8,000

Therefore, the tennis ball is 8,000 times larger than the neuron,

Step-by-step explanation:

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
