Answer:
-3.69
Step-by-step explanation:
Exponential equations can be solved by taking Ln (natural logarithm) of both sides. The rule we need to know is:

Now lets work out this problem:

Using calculator, we take the values of Ln 16 and Ln 13 as:
Ln 16 = 2.7726
Ln 13 = 2.5649
Now, we can solve for x:

x is -3.69 (rounded to 2 decimal places)
You could simplify 255
100+100+55
for each hundred there's 15$ earned so 15×2 =30$
there's 55 left and 1 till 99 =0.10 each
55×0.10=5.5$
30+5.5=35.5
in short the answer is 35.5$
Answer:
Depends on which function is which...
Step-by-step explanation:
The blue graph is the same as the yellow graph but raised up 1 unit. That means either:
blue function rule = yellow function rule + 1
or
yellow function rule = blue function rule - 1
Your picture doesn't say which function is <em>f</em> and which is <em>g</em>.
If, just to pick a possibility, the blue function is <em>g</em>(<em>x</em>), then
g(x) = f(x) + 1
If the blue function is <em>f</em>(<em>x</em>), then
g(x) = f(x) - 1
-4, -3, -2, -1
Consecutive integers are integers that are exactly one unit away from each other. -4 is one unit away from -3, and likewise with -3 and -2 and -2 and -1.
Answer:
1:
we have a rule that is (n-2)×180
while n = number of sides
2:
exterior angle of a polygon = 360 ÷ number of sides
so 360÷25=14.4
3:
octagon is 8 side, so as we said: (8-2)×180 = 1080
4:
lets make an equation, we know that (n-2)×180 = the sum
so (x-2)×180=720
180x -360 = 720
180x = 1080
x=6
