Answer:

Step-by-step explanation:

B; So this is a transformation problem from the parent function of f(x)=|x| so the function is is moved 3 units down giving it the -3 at the end and is moved to the right 7 units so it would be x-7

NEED ANSWER ASPA.... PLS HURRY

a_sh-v [17]

We have that
$y=- x^{2} +36$

we know that
Is the equation of a vertical parabola open down
so
the vertex is a maximum

step 1
convert the equation of the parabola in the vertex form
$y=- x^{2} +36 \\ y-36=- x^{2}$

the vertex (h,k) is the point (0,36)

Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)

Part b) The points on the graph where the height of the tunnel is zero feet is when y=0
so
for y=0
$- x^{2} +36=0 \\ x^{2} =36 \\ x= (+/-) 6$

the points are (-6,0) and (6,0)

see the attached figure

The graph of f(x)=2x^3+x^2-4x-2 is shown. How many of the roots of f(x) are rational

Alexeev081 [22]

We can one theorem to help us find rational roots of this polynomial.

2x^3 + x^2 - 4x - 2

We'll use Descartes' rule of signs.

Because there is 1 sign change, 1 of the 3 roots will be positive.

Now we can make the value of x -1 to see how many negative roots there will be.

-2 + 1 + 4 - 2

There are 2 sign changes, so we know there will be 2 negative roots.

Because of this, we should have 3 real, rational roots.

Need some help using some type of formula for this.

Romashka-Z-Leto [24]

This is about the weight per volume unit.

Item A has a volume of 4*5*2 = 40 ft3 and it weighs 1000 lbs.
That is 1000/40 = 25 lbs/ft3, which makes it a class 3 item.

Does that make sense to you? Can you do the rest now?
