Answer:
55°, 40° and 85°
Step-by-step explanation:
For a given triangle, the sum of its interior angles is equal to 180°.
Here, the interior angles are and .
∴
Now, plug in 20 for x and evaluate each angle.
So, °
°
°
Therefore, the measures of the angles of the triangles are 55°, 40° and 85°.
Answer:
14110
Step-by-step explanation:
Let x = number of pages ;
μ = 12200 ; σ = 820
Zscore = (x - μ) / s
Zscore = (x - 12200) / 820
Zcritical at 99% confidence, for a 1 - tail test is 2.33
Hence, Z at 99% = 2.33
Put Zscore = 2.33
Zscore = (x - 12200) / 820
2.33 = (x - 12200) / 820
2.33 * 820 = x - 12200
1910.6 = x - 12200
1910.6 + 12200 = x
x = 14110.6
x = 14111
The number of pages the manufacturer should advertise is 14,110
Looking at the graph of this exponential function, we can see the following behaviors:
When the value of x increases, the value of f(x) decreases, approaching the value y = 1 when x tends to positive infinity.
When the value of x decreases, the value of f(x) increases, going towards positive infinity.
Therefore the answers are:
As x decreases without bound, the graph of f(x):
increases without bound
As x increases without bound, the graph of f(x):
approaches y=1
I mean... You're correct.!
