73.0
Step-by-step explanation:
tan 67°=O/A=h/31
h=31tan67°
h=73.0
Answer:
The answer is -2
Step-by-step explanation:
you subtract common numbers, so:
5s - 3s = 2s
Then,
-6 + 2 = -4
You would then get
2s - 4
divide -4 by 2 which is -2
and your answer is s = -2
Answer:
The interval of increase of g(x) is .
Step-by-step explanation:
The interval of increase occurs when first derivative of given function brings positive values. Let be , the first derivative of the function is:
The following condition must be met to define the interval of increase:
The first term is always position due to the quadratic form, the second one is a first order polynomial and it is known that positive value is a product of two positive or negative values. Then, the second form must satisfy this:
The solution to this inequation is:
Now, the solution to this expression in interval notation is:
Answer:
see below
Step-by-step explanation:
The tangent function has been shifted upward by 2 units, but there has been no horizontal scaling. Any horizontal offset must be equal to some number of whole periods.
Choices A and B show tan( )+2, the correct vertical offset. However, choice A has a horizontal scale factor of 2. The correct choice is B, which has no horizontal scaling (the coefficient of x is 1) and a horizontal offset of π, one full period.

<em>Comment on horizontal scaling</em>
Horizontal scaling is different from vertical scaling in that using k·x in place of x <em>compresses</em> the graph horizontally by a factor of k. On the other hand, using k·f(x) in place of f(x) <em>expands</em> the graph vertically by a factor of k.
x has to equal 1. 3/10 + 1/5 = 1/2
the equation is now 1/2 + x = 1 1/2x
x = 1
1 1/2 = 1 1/2
