Circle R has equation

Mathematics
1 answer:
Rudiy273 years ago
5 0

Answer:

The center is (-10,10)  and the radius is 4sqrt(3)

Step-by-step explanation:

(x + 10)^2 + (y - 10)^2 = 48

We can write the equation of a circle as

(x -h)^2 + (y - k)^2 = r^2  where (h,k) is the center and r is the radius

(x-  -10)^2 + (y - 10)^2 = (sqrt(16*3) )^2

(x-  -10)^2 + (y - 10)^2 = (4sqrt(3)) ^2

The center is (-10,10)  and the radius is 4sqrt(3)

A drone is monitoring the atmospheric conditions above a farm field.
Viefleur [7K]

Answer:

y=5 \ \ \ x x_o + 1.9s

Step-by-step explanation:

This situation can be considered as a piecewise function. First, you take xo as the time in which the drone goes upward. Before this time the height of the drone is constant with a value of 5 m. Next, you take into account that during 1.9 s after xo the drone accelerates. Finally, the drone flies again with a constant height of 5.9m. Hence, this function has three parts:

For the first part you have:

y = 5       for x <  xo

For the second part you first calculate vertical speed (which means the slope of the linear function) by using the following kinematic equation:

y=vx\\\\v=\frac{y-y_o}{x}=\frac{5.9m-5.0m}{1.9s}=0.47m/s

Then you have:

y = 0.47x    for xo < x < xo + 1.9s

And for the third part:

y = 5.9    for x > xo  + 1.9s

Summarizing you obtain:

y=5 \ \ \ x x_o + 1.9s

Vlad1618 [11]

Answer:

1/(5^12 * 32^3 * 9^15)

Step-by-step explanation:

5^-12 = 1/(5^12)

32^-3 = 1/(32^3)

9^-15 = 1/(9^15)

1/(5^12) * 1/(32^3) * 1/(9^15) = 1/(5^12 * 32^3 * 9^15)

Which expression is equivalent to (8^2)^-4
xz_007 [3.2K]

Answer:

C: \frac{1}{8*8*8*8*8*8*8*8}

Step-by-step explanation:

a^{-n} = \frac{1}{a^n}

Since a = 8^2 :

(8^2)^{-n} = \frac{1}{(8^2)^n} =\frac{1}{8^{2n}}

Since n = 4 :

(8^2)^{-4} =\frac{1}{8^{2*4}}=\frac{1}{8^{8}}=\frac{1}{8*8*8*8*8*8*8*8}
