Which describes the graph of y=(x-5)^2 -4

Mathematics
1 answer:
Lerok [7]3 years ago
5 0

Answer:

Use semi-log paper for plotting Y = log y instead of y against x.

The graph is the straight line Y = (log 2) x + log 5.

Explanation:

y is function of the form

b

a

x

.

Semi-log graph is good for revealing such relationship for experimental data [(x, y)] through plots in the proximity of a straight line.

Here, taking logarithms,

Y = log y = log 5 + x log 2.= m x + c.

Slope

d

Y

d

x

is log 2 and Y-intercept is 5 on the log scale.

Graduations will show 1 unit Y = log 10. So, log 2 = 0.3019 unit of Y.

each time kim pour water from a jug into a glass, exactly 10% of the water remaining in the jug is used. What is the minimum num
Gnoma [55]

The <em><u>correct answer</u></em> is:

At least 7 times.

Explanation:

Since 10% of the water in the jug is removed each time, this means that 100-10=90% of the water remains.

After two times, we would have 0.9(0.9) = 0.81 = 81% of the water; each time she pours, the number of times 0.9 is multiplied by itself changes.  This makes this an exponential inequality (it is not an equation, as we want "less than half of the water"):

0.5 < 0.9^x

To solve this, we will use logarithms:

\log_{0.9}(0.5)
