Find the midpoint of the line segment shown below.
balu736 [363]

Answer:

x²-6x+y²-4y=-4

Step-by-step explanation:

We know the circle equation stands like this:

(x-a)² + (y-b)² = R²

and (a,b) is center

and R stands for Radius

so in this case:

center = (3,2)

R = 3

So

(x-3)² + (y-2)² = 9

x²-6x+9 + y²-4y+4=9

x²-6x+y²-4y=-4

If the temperature dropped by 7.f each hour from 5:00 am to 9:00 am. What was the beginning temperature at 5:00 am if the temper
arlik [135]

If the temperature dropped by 7.f each hour from 5:00 am to 9:00 am.  the beginning temperature at 5:00 am if the temperature at 9:00 am was -10.f is 18.f.

<h3>Beginning temperature</h3>

Dropped in temperature=7.t

Number of hours= 5:00 am to 9:00 am=4 hours

Temperature at 9:00 am=-10.f

Hence:

Beginning temperature can be calculated as:

Beginning temperature=(4× 7) + (-10)

Beginning temperature=28 + (-10)

Beginning temperature= 18.f

Check:

Since  temperature dropped by 7.f each hour from 5:00 am to 9:00 am

which implies that temperature  7.f dropped for 4 hours.

Hence:

18-7-7-7-7=-10.f

Therefore If the temperature dropped by 7.f each hour from 5:00 am to 9:00 am.  the beginning temperature at 5:00 am if the temperature at 9:00 am was -10.f is 18.f.

The radius of a right circular cone is increasing at a rate of 4 inches per second and its height is decreasing at a rate of 5 i
solmaris [256]

Answer:

V' = 900\pi in^{3} /sec

Step-by-step explanation:

V = \frac{1}{3} \pi r^{2}h

V' = \frac{2\pi rh *r'}{3}  + \frac{\pi r^{2} *h'}{3} (using differentiation product rule)

plug known values in for r, h, r', and h'

V' = \frac{2\pi (10)(40)(4)}{3} + \frac{\pi (10^{2} )(-5)}{3}

V' = \frac{3200\pi }{3} - \frac{500\pi }{3} \\V' = \frac{2700\pi }{3} \\

V' = 900\pi in^{3} /sec
