Answer:

25/81.

Step-by-step explanation:

(27/8)^-4/3

= 8^4/3 / 27^4/3

= (∛8)^4 / (∛27)^4

= 16 / 81

(64/125)^-2/3

= (125)^2/3 / (64)^2/3

= (∛125)^2 / (∛64)^2

= 5^2 / 4^2

= 25/16

So the answer is

16/81 * 25/16

= 25/81.

Prove that the following four points will form a rectangle when connected in order

Lemur [1.5K]

Answer:

Step-by-step explanation:

If the diagonals of the rectangle are congruent,

AC = BD

By using formula to calculate the distance between two points,

Distance between two points = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between A(0, -3) and C(2, 8),

AC = $\sqrt{(8+3)^2+(2-0)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Similarly, distance between two points B(-4, 0) and D(6, 5),

BD = $\sqrt{(5-0)^2+(6+4)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Therefore, both the diagonals are congruent.

Hence, given quadrilateral ABCD is a rectangle.

joyville has a population of 20,750 people. its population is increasing at a rate of 2.9% each year. what is the function?

harina [27]

Answer:

Step-by-step explanation:

Since the rate is greater than 1 this is an exponential growth function of thr form

y=ar^x, where y=final value, a=initial value, r=common ratio or rate, and x=term number

In this case a=20750, r=1.029 so

y=20750(1.029)^x
