1. What is the slope and how is it determined from a g raph?

1 answer:

6 0

Answer:

The rise divided by the run is the slope of a line. The rise and run are used to estimate the slope of a line from its graph.

To determine the intercepts from a graph, We put y equal to zero and solve for x to find the x-intercept. Similarly, we put x equal to zero and solve for y to find the y-intercept.

A wheelchair ramp is 16 feet Long. The ramp sits up on a 2 foot platform. How far is it from the end of the ramp to the bottom o

il63 [147K]

Answer:

√254 feet

Step-by-step explanation:

This is basically a triangle, with a height of 2, and hypotenuse of 16.

Using the Pythagorean theorem (a^2+b^2=h^2) we can find the other side.

2^2+b^2=16^2

4+b^2=256

b^2=254

b=√254

The point (3,0) lies on the graph of P(x)=x^3-7x^2+15x-9. True or False

swat32

Answer:

True

Step-by-step explanation:

We can plug in and see.

If (3,0) is on the graph of P, then P(3) will evaluate to 0.

Let's try it:

P(3)=(3)^3-7(3)^2+15(3)-9

P(3)=27-7(9)+45-9

P(3)=27-63+45-9

P(3)=-36+45-9

P(3)=9-9

P(3)=0

Since P(3)=0, then (3,0) is an ordered pair of P.
