What is the y-intercept of the quadratic function f(x) = (x – 6)(x – 2)? (0,–6) (0,12) (–8,0) (2,0)

Answers

Answer:

(0,12)

Step-by-step explanation:

$f(x) = (x - 6)(x - 2)$

To find out y intercept , plug in 0 for x and find out f(0)

y intercept are the value where the graph crosses y axis

$f(x) = (x - 6)(x - 2)$

$f(0)= (0-6)(0 - 2)=12$

When x is 0 the value of y is 12

Write y intercept as (0,y) that is (0,12)

Answer:

(0,12)

Step-by-step explanation:

Just plug in 0 for x so (0-6)(0-2) = 12 so that's the y value.

Also, a y intercept has to be of the form (0,y) where y is some number. The x value has to be 0, so that eliminates the last two options automatically, but if we put the x and y value we got together we get (0,12)

A bag has 5 red marbles, 6 blue marbles and 4 black marbles. What is the probability of a blue marble, replacing it, and then picking a black marble?

8/75

4/45

1/9

Answers

There are 15 total marbles in the bag, of which 6 are blue nd 4 are black.

The probability of pulling a blue marble from the full bag is 6/15 .

The probability of pulling a black marble from the full bag is 4/15 .

The probability of both events happening is

(6/15) x (4/15) = 24/225 = 8/75

A tangent-tangent angle intercepts two arcs that measure 135 degrees and 225 degrees. What is the measure of the tangent tangent angle?

Answers

Answer:

$M=45 degrees$

Step-by-step explanation:

It is given that A tangent-tangent angle intercepts two arcs that measure 135 degrees and 225 degrees, thus in this the vertex lies outside, therefore

The measure of the tangent tangent angle is the half of the difference of the two given arc, that is

$M=(1)/(2)(225-135)$

⇒ $M=(90)/(2)$

⇒ $M=45 degrees$

Therefore, The measure of the tangent tangent angle is 45 degrees.

225-130/2=45degree..
