Answer:

$distance = \sqrt{ {( - 3 - 3)}^{2} + {( - 1 - ( - 9))}^{2} } \\ = \sqrt{36 + 64} \\ = \sqrt{100} \\ = 10 \: units$

What is the recursive formula for this sequence? 24,20,16,12

kirza4 [7]

Answer:

28 - 4n

Step-by-step explanation:

What is the recursive formula for this sequence? 24,20,16,12

the sequence first term is 24

a= 24

Common difference (d) = T2 - T1 = T3 - T2

d = 20-24 = 16 -20

d = -4

Formula for nth term

Tn = a + (n-1)d

Tn = 24 + (n -1)-4

Tn = 24 -4n + 4

Tn = 28 - 4n

= 28 - 4n

Jason and Kyle both choose a number from 1 to 10 at random. What is the probability that both numbers are odd?

Artemon [7]

Your answer is

B) 1/2

because there are 5 odd and 5 even numbers from 5 through 10, so it would be 1/2.

Glad I could help, and good luck!

Cos^(2)x=(cscxcosx)/(tanx+cotx)

bixtya [17]

$\cos^2 x = \dfrac{\csc x \cos x}{\tan x + \cot x}$

$\cos^2 x = \dfrac{\csc x \cos x}{\dfrac{\sin x}{\cos x} + \dfrac{\cos x}{\sin x}}$

$\cos^2 x = \dfrac{\csc x \cos x}{\frac{\sin x}{\cos x} \times 
\frac{\sin x}{\sin x} + \frac{\cos x}{\sin x} \times \frac{\cos x}{\cos 
x}}$

$\cos^2 x = \dfrac{\csc x \cos x}{\frac{\sin^2 x}{\sin x \cos x} + \frac{\cos^2 x}{\sin x \cos x}}$

$\cos^2 x = \dfrac{\csc x \cos x}{\frac{1}{\sin x \cos x}}$

$\cos^2 x = \csc x \cos x \sin x \cos x$

$\cos^2 x = \dfrac{1}{\sin x} \cos x \sin x \cos x$

$\cos^2 x = \cos^2 x$

9·8·7! is equivalent to:<br><br> 9 x 8 x 7<br> 72 x 5,040<br> 504!

liq [111]

Answer:

$\large\boxed{9\cdot8\cdot7!=72\times5,040}$

Step-by-step explanation:

$n!=1\cdot2\cdot3\cdot...\cdot n\\\\\text{Therefore}\\\\7!=1\cdot2\cdot3\cdot4\cdot5\cdot6\cdot7=5,040\\\\9\cdot8=72\\\\\text{Finally:}\\\\9\cdot8\cdot7!=72\times5,040$
