Mathematics
1 answer:
garri49 [273]4 years ago
6 0

Answer:

19 or 21.

Step-by-step explanation:

I swear.

5 + 5 = 10

10 + 5 = 15

15 + 4 = 19

________________

9 + 9 = 18

18 + 10 = 28

28 - 5 = 23

There are two nines so

23 - 2 = 21

If the endpoints of the diameter of a circle are (−10, −8) and (−6, −2), what is the standard form equation of the circle?
balandron [24]
First, find the midpoint of the diameter. the midpoint is the center of the circle.
[(-10+(-6)]/2=-8, [(-8+(-2)]/2=-5
so the center is at (-8, -5)
next, find the distance between the two points:
d=√[-6-(-10)]²+[-2-(-8)]²=√4²+6²=√52=2√13
half of the diameter is radius, r=half of 2√13=√13
standard equation for the circle is (x-h)²+(y-k)²=r², (h,k) being the center, r the radius
(x+8)²+(y+5)²=13 is the answer.

A spherical party balloon is being inflated with helium pumped in at a rate of 10 cubic feet per minute. How fast is the radius
Anastaziya [24]

Answer:

The radius is growing at a rate of   \frac{dr}{dt}  = \frac{10}{4 \pi} = 0.795 ft per minute.

Step-by-step explanation:

From the information given we know that

\frac{dV}{dt} = 10

And we know as well that .

V = \frac{4}{3} \pi r^3

Since everything is changing with the time we can compute the implicit  derivative and we would get that

\frac{dV}{dt} = 10 = 4\pi r^2 \frac{dr}{dt}

We are told that we are looking for how fast is the radius growing at the instant when the radius has reached 1 ft, therefore  r = 1.

And when we solve for  \frac{dr}{dt}  = \frac{10}{4 \pi} = 0.795
