Circle equation
(x-h)^2 + (y-k)^2 = r^2
where (h.k) is the center and r is the radius
(x -7)^2 + (y+10)^2 = 4

Answer:

Step-by-step explanation:

Two sum of any two side lengths of a triangle will always be greater than the length of the remaining side

a doesn't work because 8+12=20 and 20 is not greater than 20

b doesn't work because 4+5=9 and 9<10

d doesn't work because 6+6=12 and 12 is not greater than 12

c is the only option where you can take any two sides, add them, and the sum will be greater than the remaining side.

For example, for c,

6+8=14, and 14>10

8+10=18, and 18>6

10+6=16, and 16>8

4. Find x, the missing<br> side length in the right<br> triangle.

Kaylis [27]

Answer:

16.703

Step-by-step explanation:

right angle triangle thus we use puthagoras theorem to find the unknown length.

By converse of pythagoras theorem,

c² = a² + b²

c = √a² + b²

where c is the hypothenuse, a and b can be any 2 side of the right angle triangle

so x = √c² - a² = √ 20² - 11² ≈ 16.703 (or u can use calculator to find the long string of decimals and then round off on your own)

Rewrite the function by completing the square. f ( x ) = x 2 − 8 x − 51 f(x)=x 2 −8x−51

Nina [5.8K]

Answer:

(x-4)^2 - 67

Step-by-step explanation:

f ( x ) = x^ 2 − 8 x − 51

Take the coefficient of x

-8

Divide by 2

-8/2 = -4

Square it

(-4)^2 = 16

Add this and subtract it

f ( x ) = x^ 2 − 8 x +16 -16− 51

= (x^2 -8x+16) - 67

= (x-4)^2 - 67

Assume that a procedure yeilds a binomial with n trial and the probability of success for one trial is p. Use the given values o

Alexeev081 [22]

The value of minimum usual value is, $\mu-2\sigma=-119.2$

The value of maximum usual value is, $\mu+2\sigma=1311.2$

Given the values of the parameters of Binomial Distribution are,

Total number of trials (n) = 1490

probability of success in one trial is (p) = 2/5

The probability of failure in on trial is given by,

$q=1-p=1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}$

For Binomial distribution we know that,

Mean $(\mu)=np=1490\times\frac{2}{5}=596$

and Standard Deviation $(\sigma)=\sqrt{npq}=\sqrt{1490\times\frac{2}{5}\times\frac{3}{5}}=357.6$

Now, calculating the required measurement we get,

The minimum usual value is given by,

Mean -2 Standard Deviation $=\mu-2\sigma=596-2\times357.6=-119.2$

The maximum usual value is given by,

Mean + 2 Standard Deviation $=\mu+2\sigma=596+2\times357.6=1311.2$

Hence the minimum and maximum usual values are -119.2 and 1311.2 respectively.
