The second and third highest temperatures were -8 and 7, you just need to state a value between those; such as 3 or 4.

Hope this helps :)

Please tell me correct and

choli [55]

Answer:

$\frac{1}{4}$ or $0.25$ (they're the same)

Step-by-step explanation:

First Part:

$4^{3} = 64$
$8^{2} = 64$
$2 = 2$
Multiply them together: 64 × 64 × 2 = 8192

Second Part:

$2^{7} = 128$
$16^{2} = 256$
Multiply them together: 128 × 256 = 32768

Wrap it all up:

8192 ÷ 32768 = 0.25 = 1/4

I hope this helps!

The explicit formula for an arithmetic sequence is an = 20 + (n − 1)(2). What is the 200th term?

Andrews [41]

Answer:

$a_{200}=418$

Step-by-step explanation:

The explicit formula for an arithmetic sequence is given by :

$a_n=20+(n-1)2$ ...(1)

We need to find the 200th term of the sequence.

Put n = 200 in equation (1)

$a_{200}=20+(200-1)2\\\\=20+199\times 2\\\\=418$

So, the 200th term of the sequence is 418.

Which equation represents the hyperbola in general form?

valina [46]

ANSWER

$9 {y}^{2} - 4 {x}^{2}- 36y + 16x - 16 = 0$

EXPLANATION

The standard equation of the hyperbola is

$\frac{ {(y - 2)}^{2} }{4} - \frac{ {(x - 2)}^{2} }{9} = 1$

We multiply through by 36 to obtain:

$9 {(y - 2)}^{2} - 4( {x - 2)}^{2} = 36$

We now expand to get,

$9( {y}^{2} - 4y + 4) - 4( {x}^{2} - 4x + 4) = 36$

Expand :

$9 {y}^{2} - 36y + 36 - 4 {x}^{2} + 16x - 16 = 36$

To get the general form, we equate everything to zero to get,

$9 {y}^{2} - 4 {x}^{2}- 36y + 16x - 16 = 0$

The correct choice is D.
