The point which would lie on the graph of f(x) = log2x is; (1, 0.301).

<h3>Which point would lie on the graph of f(x) = log2x?</h3>

Since it follows from the task content that the given point (–1, 0.5) lies on the graph of f –1(x) = 2x.

The subsequent graph of f(x) = log2x would result from taking logarithms in which case, we have the graph passing through points determined as follows;

f(x) = log2^x

f(x) = x log2

Hence, when x = 1;

f(1) = 1log 2

Hence, we have point; (1, 0.301).

The grizzly bear population in yellowstone national park in 1970 was about 270.Over the next 35 years,it increased by about 115%

yawa3891 [41]

Answer:

581

Step-by-step explanation:

<u>Population of Grizzlys</u>

1970 >>> 270

2005 >>> 115% INCREASE

We need to find 115% of 270 and increase 270 by that amount. Firstly, converting percentage to decimal (division by 100):

115/100 = 1.15

So, that would be now:

1.15 * 270 = 310.5

Increasing, we get:

270 + 310.5 = 580.5

We round to 581

In 2005, the population was about 581

the second term in a geometric sequence is 12. the fourth term in the same sequencce is 4/3. what is the common ratio in this se

nordsb [41]

Geo is
an=a1r^(n-1)

2nd term is 12
4th term is 4/3

a2=a1r^(2-1)=12
a2=a1r=12

a4=a1r^(4-1)=4/3
a4=a1r^3=4/3

we have
a1r=12 and a1r^3=4/3
(a1r^3)/(a1r)=r^2=(4/3)/12=1/9

1/9=r^2
sqrt oth sides
1/3=r

the common ratio is 1/3

Sketch the graph of each line.<br> 1) y = -x +3<br> toto 4 3 2 1

seropon [69]

Answer:

I can't draw the graph for you here, but the y intercept is 3, and the slope is -1.

Step-by-step explanation:

First you plot a point on the y axis at 0,-3

Then you want to do a rise over run, doing -1,1 until you get enough points to graph the line.
