Answer:

(b) 36 degrees.

Step-by-step explanation:

K is the center of the circle so triangle KMN is isosceles and m < KMN = m KNM = 26 degrees ( base angles are equal)

So m < LMK = m <LMN - m < KMN

= 98 - 26

= 72 degrees.

Now triangle LKM is also isosceles since K is the center of the circle so

m < LKM = 180 - 2* 72

= 180 - 144

= 36 degrees.

What are the x intercepts of the quadratic function? Y=-x^2+2x-1

saw5 [17]

Answer:

x = 1

Step-by-step explanation:

Given in the question the equation

y = -x² + 2x - 1

To find the x-intercept, substitute in 0 for y

0 = -x² + 2x - 1

To find value of x use quadratic equation

x = -b ± √b²-4ac / 2a

here a = -1

b = 2

c = -1

x1 = -2 + √2²-4(-1)(-1) / 2(-1)

= -2 + 0 / -2

= -2 / -2

= 1

x2 = -2 - √2²-4(-1)(-1) / 2(-1)

= -2 - 0 / -2

= -2 / -2

= 1

Answer:

There are 3478761 ways to select the first 5 numbers

Step-by-step explanation:

As understood from the statement of this problem we assume that it does not matter the order in which the first 5 white balls are selected.

In this case it is a combination.

So, what we want to know is how many ways you can choose 5 white balls out of 55.

Then we use the formula of combinations:

$C(n, x) = \frac{n!}{x! (n-x)!}$

Where you have n elements and choose x from them.

Then we look for:

$C(55, 5) = \frac{55!}{5!(55-5)!}\\\\C(55, 5) = \frac{55!}{5!(50)!}\\\\C(55, 5) = 3478761$
