tan x < cos x
Answers
Answer:
(-1.570796, 0.666239) ∪ (1.570796, 2.475353)
Step-by-step explanation:
A graphing calculator can give you the numerical values that limit the intervals of the solution. The attachment shows this solution.
__
algebraic solutionWe can multiply by cos(x) and solve the resulting quadratic inequalities. Two cases arise:
tan(x) -cos(x) < 0 . . . . . . subtract cos(x)
sin(x) -cos(x)² < 0 . . . . . . . for cos(x) > 0
sin(x) -cos(x)² > 0 . . . . . . . for cos(x) < 0 (inequality is reversed)
Replacing cos(x)² with (1 -sin(x)²) gives quadratic equations in sin(x). (We're using <> to mean "could be greater than; could be less than, depending on cos(x)".)
sin(x) -(1 -sin(x)²) <> 0
sin(x)² +sin(x) -1 <> 0 . . . . put in standard form
(sin(x)² +sin(x) +1/4) -1 -1/4 <> 0 . . . . complete the square
(sin(x) +1/2)² -5/4 <> 0 . . . . . write as a square
((sin(x) +1/2)-√(5/4))·((sin(x) +1/2) +√(5/4)) <> 0 . . . . factor
Note that the second factor is always positive, so it has no impact on the intervals of solution.
__
The zeros of the first factor are located at ...
sin(x) = 1/2(-1 +√5)
x ≈ 0.666239 radians, and π - 0.666239 radians ≈ 2.475353 radians
The sine function will be positive between these angle values.
__
However, the intervals of solution to the inequality depend on the cosine function. Effectively, the solution space is where (sin(x) +(1-√5)/2) and cos(x) have opposite signs.
cosine positiveThe cosine function is positive for -π/2 < x < π/2, so one of the intervals of solution will be ...
-π/2 < x < arcsin((√5 -1)/2), approximately (-1.570796, 0.666239)
cosine negativeThe cosine function is negative for -π < x < -π/2 and for π/2 < x < π. The other interval of solution will be ...
π/2 < x < (π -arcsin((√5 -1)/2)), approximately (1.570796, 2.475353)
_____
Additional comment
In the above, we have used α=arcsin( ) to mean the values of angle in the principal branch: -π/2 ≤ α ≤ π/2. That is why we have to subtract it from π to find the other end of the interval of interest.

You can catch a bus near your home to and from work for $3.75 a day. The monthly pass is
$70. Assuming that you work about 22 days a month, how much can you save by buying the
pass?
O $5.00
O $3.75
O $12.50
O $82.50
Answers
Answer:
$12.50
Step-by-step explanation:
I multiplied $3.75 by 22 to figure out how much you would make in that month.
3.75 x 22 = $82.50
I then subtracted $70 from $82.50 to figure out how much you would have left after buying the pass.
82.50 - 70 = $12.50

Anthony drove 140 miles in 2 1/2 hours. He then drove the next 3 1/4 hours at a rate that was 6 miles per hour slower than his first rate. How many miles did Anthony drive in all?
Answers
Answer:
302.5 miles
Step-by-step explanation:
using the relationship
D = ST ( D is distance, S is speed and T is time in hours )
given he drove 140 miles in 2 [tex]\frac{1}{2}[/tex] = 2.5 hours , then
S = [tex]\frac{D}{T}[/tex] = [tex]\frac{140}{2.5}[/tex] = 56 mph
the next part of his journe is 6mph slower, that is 50 mph for 3 [tex]\frac{1}{4}[/tex] = 3.25 hours, then
D = ST = 50 × 3.25 = 162.5 miles
total distance travelled = 140 + 162.5 = 302.5 miles

We can find the height of the tower without measuring it. WE can find the height of the tower when we know,
1. A point which at a distance 'x' from the foot of the tower.
2. The angle of elevation is known
Eg: A tower stands vertically on the ground. From a point on the ground which is 15 m away from the foot of the tower, the angle of elevation of the top of the tower is 60°. Find the height of the tower.
AB - tower
We know the adjacent side of 60° and we have to fing the opposite side of 60°. So, we have to use
[tex]\sf \ Tan \ 60^\circ=\dfrac{Opposite \ side \ of \ 60^\circ}{Adjacent \ side \ of \ 60^\circ}[/tex]
[tex]1.732 = \dfrac{AB}{BC}\\\\1.732=\dfrac{AB}{15}\\\\1.732*15=AB[/tex]
AB = 25.98 m
Height of the tower ≈ 26 m
A quadratic equation has the solutions x- -5 and x=4 What are the x-intercepts of the graph of the function?

Step-by-step explanation:
"Solutions" in this case have the same numeric values as do "x-intercepts."
If x = -4 is a "solution" of this quadratic equation, then (-4, 0) is the corresponding x-intercept. Likewise, if x = 1 is a solution, then (1, 0) is the corresponding x-intercept.

y = 3x - 1
y = -3x -1
y = -⅓x -1
y = 3x + 1
Answers
Answer:
y = -3x - 1
Step-by-step explanation:
To find the slope, use the slope formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Plugging in the given values, we have: [tex]\frac{-4-2}{1-(-1)}[/tex]
[tex]\frac{-4-2}{1-(-1)}[/tex]
= [tex]\frac{-6}{2}[/tex]
= -3
Now that we know that the slope is -3, we need to find the y-intercept. Anazlyzing the graph, we can see that the line passes through the point (0, -1) on the y-axis, therefore, that is our y-intercept.
Combining the information, the result is: y = -3x - 1

y=1/3x
Step-by-step explanation:A linear function is a relationship that has a degree of 1 and a constant slope. Linear functions are written in the form of y=mx+b, where m is the slope and b is the y-intercept.
Y-intercept
The y-intercept of a function is the y-value when x=0. In this case, we are given all of the coordinates. One of the coordinates is (0,0), which means that when x=0, y=0. So, the y-intercept is 0.
Slope
The slope is the change in y over the change in x. Using the coordinates we can find the slope through the formula [tex]\frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]. It will be easiest to use the coordinates (0,0) and (3,1). Plug these points into the formula to find the slope.
[tex]\frac{1-0}{3-0}[/tex] = [tex]\frac{1}{3}[/tex]This means that the slope is 1/3.
Answer
Using the information found in the previous sections we can create the final answer, y=1/3x+0, or just y=1/3x.
