Explain why the graphing calculator cannot be used to solve or approximate solutions to all polynomial equations.

Lelu [443]

Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>

The measure of minor arc JL is 60°.

stellarik [79]

Answer:

m∠JKL = 120°

Step-by-step explanation:

The measure of an angle formed by a two tangents drawn from a point outside the circle is the the difference of the intercepted arcs

minor arc JL = 60 major arc JL = 360 - 60 = 300

m∠JKL = 1/2(300 - 60) = 1/2(240) = 120

A right rectangular prism has these dimensions:

DochEvi [55]

Hey there :)

The volume formula of a rectangular prism is
V = height x length x width

Given are:
Length = $1\frac{1}{2} = \frac{3}{2}$
Width = $\frac{1}{2}$
Height = $\frac{3}{4}$

Lets find the volume:
V = $\frac{3}{2}$ x $\frac{1}{2}$ x $\frac{3}{4}$
= $\frac{9}{16}$ units³

The volume formula of a cube is
V = side³

Given is:
Side = $( \frac{1}{4} )^3$
= $\frac{1}{64}$ units³

To find how many cubes fit in the rectangular prism, we divide the volumes
Volume of prism divided by volume of cube
$\frac{9}{16}$ ÷ $\frac{1}{64}$
Since it is a fraction that is involved in division, we find the reciprocal and multiply

= $\frac{9}{16}$ x 64
= 36

Your answer will be the 1st option
