podryga [215]

Answer:

Well to estimate a decimal the best option would be to round it to.

10 or 11 (For 10.9)

11 (For 11.1)

and since two of them equal 11. 

The estimation would be 11.

I hoped this helped.

In Exercise, describe how the graph of g is related to the graph of f.<br> g(x)=-1+f(x)
Jet001 [13]

Answer:

The graph of g is the graph of f shifted down 1 unit.

Step-by-step explanation:

Suppose you have a function y = f(x), you can do these following operations on the function:

Shift up a units: y = f(x) + a

Shift down a units: y = f(x) - a

Shift left a units: y = f(x + a)

Shift right a units: y = f(x - a)

In this problem, we have that:

g(x) = -1 + f(x) = f(x) - 1

So the graph of g is the graph of f shifted down 1 unit.

What is the area of triangle abc below? If necessary, round your answer to two decimal places..... PLEASE PLEASE HELP ME
antiseptic1488 [7]
For a triangle:
A=\frac{bh}{2}
A=\frac{b \times 7.9}{2}
b=AD+DC
Use Pythagorean theorem twice:
AD^{2}+9.4^{2}=7.9^{2}
AD=5.09

DC^{2}+23.2^{2}=7.9^{2}
DC=21.81

Thus:
b=26.9

And:
Area=\frac{26.9 \times 7.9}{2}=106.26
