FInd the value of x, between -π and π, satisfying the following inequality.
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.

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 designer makes the sketch shown below for a new lamp. What is the approximate area of her sketch?
The lamp shade is a trapezoid. Its area is approximately square inches. The bases of the lamp are two trapezoids. The area of each is approximately square inches. In total, the area is approximately square inches.
Answers
The approximate area of the sketch for the new lamp is : A = 70 [tex]in^{2}[/tex]
What is a TrapeziumA trapezium is one pair of parallel sides and one pair of non-parallel sides.
from the diagram we can extract the necessary information needed to find the area of the trapezium.
for the first trapezium (lamp shade)
a = 4 in
b = 6 in
h = 6 in
[tex]A_{1}[/tex] = [tex]\frac{a + b}{2}[/tex] * h
[tex]A_{1}[/tex] = [tex]\frac{4 + 6}{2}[/tex] * 6
[tex]A_{1}[/tex] = [tex]\frac{10}{2}[/tex] * 6
[tex]A_{1}[/tex] = 5 * 6 = 30[tex]in^{2}[/tex]
For the area of the second trapezium (lamp base)
a = 4 in
b = 6 in
h = 4 in
[tex]A_{2}[/tex] = [tex]\frac{a + b}{2}[/tex] * h
[tex]A_{2}[/tex] = [tex]\frac{4 + 6}{2}[/tex] * 4
[tex]A_{2}[/tex] = [tex]\frac{10}{2}[/tex] * 4
[tex]A_{2}[/tex] = 5 * 4 = 20[tex]in^{2}[/tex]
For the area of the third trapezium (lamp base)
a = 6 in
b = 4 in
h = 4 in
[tex]A_{3}[/tex] = [tex]\frac{a + b}{2}[/tex] * h
[tex]A_{3}[/tex] = [tex]\frac{6 + 4}{2}[/tex] * 4
[tex]A_{3}[/tex] = [tex]\frac{10}{2}[/tex] * 4
[tex]A_{3}[/tex] = 5 * 4 = 20[tex]in^{2}[/tex]
The total Area of the trapezium (lamp)
A = [tex]A_{1}[/tex] + [tex]A_{2}[/tex] + [tex]A_{3}[/tex]
A = 30 + 20 + 20
A = 70 [tex]in^{2}[/tex]
Inconclusion The approximate area of the sketch for the new lamp is : A = 70 [tex]in^{2}[/tex]

Which function is graphed on the right? y = 2x 3 – 2 y = 2x–3 2 y = 2x–2 3 y = 2x–2 – 3
Answers
The equation of the function which is graphed on the right is specified by: Option C: y = 2^{x-2} + 3
How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
Since there is no graph available, we will work with the image attached below.
The function, as visible is tending to output 3 and x goes more and more negative.
That means:
[tex]\lim_{x\rightarrow -\infty}f(x) = 3[/tex] (assuming the predicted pattern is true).
Checking this for all the options:
Case 1: [tex]y = f(x) = 2^{x+3} - 2[/tex]
[tex]\lim_{x\rightarrow -\infty}f(x) = \lim_{x\rightarrow -\infty} 2^{x+3} -2 = -2[/tex]
Thus, the graph doesn't belong to this function.
Case 2: [tex]y = f(x) = 2^{x-3} + 2[/tex]
[tex]\lim_{x\rightarrow -\infty} f(x) = \lim_{x\rightarrow -\infty}2^{x-3} + 2 = 2[/tex]
Thus, the graph doesn't belong to this function.
Case 3: [tex]y = f(x) = 2^{x-2} +3[/tex]
[tex]\lim_{x\rightarrow -\infty}f(x) = \lim_{x\rightarrow -\infty} 2^{x-2} +3 = 3[/tex]
Thus, the graph may belong to this function. (we are still not sure since the last option may also have same limit, which if is found to be true, then additional findings would've to be done too).
Case 4: [tex]y = f(x) = 2^{x-2} - 3[/tex]
[tex]\lim_{x\rightarrow -\infty}f(x) = \lim_{x\rightarrow -\infty} 2^{x-2} -3 = -3[/tex]
Thus, the graph doesn't belong to this function.
Thus, assuming at least one option is true, the graph of the considered function on the right is of the function [tex]y = f(x) = 2^{x-2} +3[/tex]

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
