State the restrictions, if any. F(x)= x/x2-81

Mathematics
1 answer:
Crazy boy [7]3 years ago

Answer:

f=1/x^2-81

Step-by-step explanation:

Step 1: Multiply both sides by x^2-81.

fx3−81fx=x

Step 2: Factor out variable f.

f(x3−81x)=x

Step 3: Divide both sides by x^3-81x.

f(x3−81x)

x3−81x =x x3−81x f= 1 x2−81

Which statement can john use this figure to prove
Brums [2.3K]

Answer:

The correct option is;

The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects

Step-by-step explanation:

With the assumption that that the question meant that ΔACD and ΔBCD are congruent, we have;

Segment \overline {AC} is congruent to segment \overline {BC} by Congruent Parts of Congruent Triangles are Congruent, CPCTC

Similarly, segment \overline {DA} is congruent to segment \overline {DB} by Congruent Parts of Congruent Triangles are Congruent, CPCTC

Therefore, the points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects

In AGHI, h = 300 inches, G=30° and H=29º. Find the length of i, to the nearest<br> inch.
dalvyx [7]

Given:

In triangle GHI, h = 300 inches, G=30° and H=29º.

To find:

The length of i.

Solution:

We have, G=30° and H=29º.

Using angle sum property, we get

m\angle G+m\angle H+m\angle I=180^\circ

30^\circ+29^\circ+m\angle I=180^\circ

59^\circ+m\angle I=180^\circ

m\angle I=180^\circ-59^\circ

m\angle I=121^\circ

According to Law of sines,

\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}

Using Law of sines, we get

\dfrac{h}{\sin H}=\dfrac{i}{\sin I}

\dfrac{300}{\sin 29^\circ}=\dfrac{i}{\sin 121^\circ}

\dfrac{300}{0.4848}=\dfrac{i}{0.8572}

Multiply both sides by 0.8572.

\dfrac{300}{0.4848}\times 0.8572=i

530.44554=i

i\approx 530

Therefore, the length of i is about 530 inches.
