Answer:

Step-by-step explanation:

hello :

f(x) = a(x - h)²-k   ....vertex form  when the vertex is : (h,k)

h=1  and  k=0   so : f(x) = a(x-1)²

a parabola that passes through the point (2,8) : f(2)=8

a(2-1)² =8

a= 8

f(x) = 8(x-1)²=  8(x²-2x+1)

f(x) 8x²-16x+8   .....standard form

Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each mi
Sedbober [7]

Answer:

The slope of the equation is -3.          

Step-by-step explanation:

Given : Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute.

To find : What is the slope ?

Solution :

Let x be the number of minutes taken to dig the ground.

He started digging his way deeper into the ground, descending 3 meters each minute i.e. '-3x'

Let y is the total distance travel to dig the ground.

Mr. Mole's burrow lies 5 meters below the ground.

The equation form is y=-3x-5

Comparing with general slope form i.e. y=mx+c where m is the slope.

The slope of the equation is -3.

Three black beads, two red beads, and a yellow bead are arranged in a line. What is the probability that no black bead is adjace
shtirl [24]

Answer:

Probability of no black bead is adjacent to the yellow bead is = 0.966

Step-by-step explanation:

First to arrange all the beads without restrictions = 6! = 720

Probability the black bead is adjacent to Yellow bead = 4!/6! = 24 /720

= 0.0333

Probability of no black bead is adjacent to the yellow bead is

= 1- Probability the black bead is adjacent to Yellow bead

= 1-0.033

= 0.966
