The question is related to trigonometry and we have to use the formula of double angle .
Here we use double angle formula of tangent function which is
Given expression is
Comparing it with double angle formula, we will get x = 5
SO the required expression is equal to
So the answer is tan(10) .
Answer:
0.25
Step-by-step explanation:
The only constant in the equation is called the "constant of proportionality." Its value is 0.25.
The constant of proportionality is 0.25.
____
In an equation of the form ...
y = kx
the constant k is called the <em>constant of proportionality</em>. It's a vocabulary (naming) question.
D.
Because it is the value when charms = 0
Answer:
8 intersections
Step-by-step explanation:
Miss Stevens drove through a total of 36 intersections on her way home from work last week.
At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .
This is calculated as:
36 intersections ÷ 16 intersections
= 2 4/16
= 2 1/4
At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .
4 of every 16 intersections = stop for a red light
Hence:
16/4 = 4 intersections
Hence: 4 intersections = 1 stop for a read
The number of intersections that Miss Stevens had to stop for a red light is:
2 × 4 intersections = 8 intersections
A function is differentiable if you can find the derivative at every point in its domain. In the case of f(x) = |x+2|, the function wouldn't be considered differentiable unless you specified a certain sub-interval such as (5,9) that doesn't include x = -2. Without clarifying the interval, the entire function overall is not differentiable even if there's only one point at issue here (because again we look at the entire domain). Though to be fair, you could easily say "the function f(x) = |x+2| is differentiable everywhere but x = -2" and would be correct. So it just depends on your wording really.
