The equation of a circle is x^2 + (y - 10)^2 = 16. What is the radius and center?

gizmo_the_mogwai [7]

Answer:

Center = (0, -10)

Radius = 4 units

Step-by-step explanation:

$x^2 + (y - 10)^2 = 16\\(x-0)^2 + (y - 10)^2 = 4^2\\Equating\: it \: with\: \\(x-h)^2 + (y - k)^2 = r^2\\We\: find:\\-h = 0\implies h = 0\\-k = -10\implies k = 10\\Center = (-h,\:-k) \\Center = (0,\:-10) \\r^2 = 4^2\implies r = 4\\Radius = 4\:units$

Look Down Below For question:

Ray Of Light [21]

The cattle train
speed - 36.5 km/h
time - x h

the passenger train
speed - 29.2 km/h
time - (2.4+x) h

The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.

$36.5 \times x=29.2 \times (2.4+x) \\
36.5x=70.08+29.2x \\
36.5x-29.2x=70.08 \\
7.3x=70.08 \\
x=\frac{70.08}{7.3} \\
x=9.6 \\ \\ 2.4+x=2.4+9.6=12$

The passenger train travelled for 12 hours before the cattle train caught up.

Bacteria can multiply at an alarming rate when each bacteria splits into two new cells, thus doubling. If we start with only one

Elan Coil [88]

Answer:

2^24 = 16,777,216 bacterias.

Step-by-step explanation:

So we start with 1 bacteria

after 1 hours: 2*1 = 2

after 2 hours: 2*2 = 2^2 = 4

after 3 hours: 2*2^2 = 2^3

after n hours: 2^n

Since one day has 24 hours we have n = 24 and total number of bacteria will

be: 2^24 = 16,777,216 bacterias.
