The equation for the circle is:

balu736 [363]

Answer:

(-7, -5)

Step-by-step explanation:

x² + y² + 14x + 10y − 7 = 0

Strategy:

Convert the equation to the centre-radius form:

(x - h)² + (y - k)² = r²

The centre of the circle is at (h, k) and the radius is r

Solution:

Group x and y terms together; move the number to the right-hand side.

x² + 14x + y² + 10y = 7

Complete the square for x

(Take half the coefficient of x, square it, and add to each side of the equation)

(14/2)² = 7² = 49

(x² + 14x + 49) + (y² + 10y) = 56

Complete the square for y

(Take half the coefficient of y, square it, and add to each side of the equation)

(10/2)² = 5² =25

(x² + 14x + 49) + (y² + 10y + 25 ) = 81

Express the result as the sum of squares

(x + 7)² + (y + 5)² = 9²

h = -7; k = -5; r = 9

The centre of the circle is at (-7, -5).

The graph of the circle below has its centre at (-7, -5) and radius 9.

Can anybody answer this question? I still don't understand maths

meriva

Step-by-step explanation:

$\frac{3}{x - 4} = \frac{2}{x + 1} \\3 (x + 1) = 2(x - 4) \\ 3x + 3 = 2x - 8 \\ 3x - 2x = - 8 - 3 \\ x = - 11$

3 3⁄10 - 2 23⁄100 = please help

Charra [1.4K]

Answer:

107/100 or 1 7/100 or 1.07

Step-by-step explanation:

Turn into improper fraction: 33/10 - 223/100

Find LCM: which is 10 because 10*10 = 100 and make common denominators

330/100 - 223/100 = 107/100 or 1 7/100

Hope this helped!

Given one of the roots of the quadratic equation px2- 4x + 3p -8 =0 is 1 . Calculate the value of p

Natali [406]

Answer:

Value of p is 3

Step-by-step explanation:

One of the root is 1.

So, putting 1 in the place of x in the given equation,

px²-4x+3p-8=0

or, p-4+3p-8=0

or, 4p-12=0

or, 4p=12

or, p=3

The easy thing to do is notice that 1^4 = 1, 2^4 = 16, 3^4 = 81, and so on, so the sequence follows the rule $n^4+1$ . The next number would then be fourth power of 7 plus 1, or 2402.

And the harder way: Denote the n-th term in this sequence by $a_n$ , and denote the given sequence by $\{a_n\}_{n\ge1}$ .

Let $b_n$ denote the n-th term in the sequence of forward differences of $\{a_n\}$ , defined by

$b_n=a_{n+1}-a_n$

for n ≥ 1. That is, $\{b_n\}$ is the sequence with

$b_1=a_2-a_1=17-2=15$

$b_2=a_3-a_2=82-17=65$

$b_3=a_4-a_3=175$

$b_4=a_5-a_4=369$

$b_5=a_6-a_5=671$

and so on.

Next, let $c_n$ denote the n-th term of the differences of $\{b_n\}$ , i.e. for n ≥ 1,

$c_n=b_{n+1}-b_n$

so that

$c_1=b_2-b_1=65-15=50$

$c_2=110$

$c_3=194$

$c_4=302$

etc.

Again: let $d_n$ denote the n-th difference of $\{c_n\}$ :

$d_n=c_{n+1}-c_n$

$d_1=c_2-c_1=60$

$d_2=84$

$d_3=108$

etc.

One more time: let $e_n$ denote the n-th difference of $\{d_n\}$ :

$e_n=d_{n+1}-d_n$

$e_1=d_2-d_1=24$

$e_2=24$

etc.

The fact that these last differences are constant is a good sign that $e_n=24$ for all n ≥ 1. Assuming this, we would see that $\{d_n\}$ is an arithmetic sequence given recursively by
