Solve by completing the square p^2 +10p - 3 = 0

Mrac [35]

Solving $p^2 +10p - 3 = 0$ by completing the square method we get $(p+5)^2-28=0$

Step-by-step explanation:

We need to solve by completing the square method.

We are given: $p^2 +10p - 3 = 0$

The Completing square method is: (a+b)^2 = a^2+2ab+b^2

Solving:

$p^2 +10p - 3 = 0\\For \,\,making\,\,perfect\,\,square\,\,we\,\,add\,\,and\,\,subtract\,\,(5)^2\\p^2+2(p)(5)^2+(5)^2-3-(5)^2=0\\(p+5)^2-3-25=0\\(p+5)^2-28=0$

Solving $p^2 +10p - 3 = 0$ by completing the square method we get $(p+5)^2-28=0$

If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tent

USPshnik [31]

Answer:

12.71in

step explanation:

The Length of an arc given is expressed as;

A = theta/360 * 2πr

10 = 45/360 * 2 * 3.14r

10 = 1/8 * 6.28r

Cross multiply

10 * 8 = 6.28r

80 = 6.28r

r = 80/6.28

r = 12.74in

Hence the radius is 12.71in

Write (3 − 7i) − (-11 + 5i) as a complex number in standard form.

Arturiano [62]

The answer would be A) 14 - 12i

Simplify ( 3 - 7i + 11 - 5i )

Gather like terms ( 3 + 11 ) + ( -7i - 5i )

Simplify ( 14 - 12i ).

"We keep tossing a fair coin n = 10^6 million times, write down the outcomes: it gives a Heads-and-Tails-sequence of length n. W

anyanavicka [17]

Answer:

Check the explanation

Step-by-step explanation:

Let $X_{i}$ be the indicator random variable that takes the value 1 if the ith coin is the first coin in a sequence of 19 consecutive heads.

For any sequence of length 19, the starting coin can be from toss i ,

such that i is between 1 and n - 19+1

Thus the number of such sequences is
