Answer:
I think it's cot(135°)
Step-by-step explanation:
Cot 135° = Cot (π/2 + 45)
and,
Cot (π/2+45)= -tan (45),
because when a trigonometric ratio is impressed by using π/2 the ratio should be changed its opposite like sin value turns into a cos value, tan value turns into cot and vise versa. Then as 135° is in the second sector that means π/2<135°<π. So it should be -tan(45°)
As tan-45°= -tan 45° i think the answer is second one aka cot(135°)
The equivalent expression of tan(-45) is cot(135)
The given trigonometric expression is: tan(-45).
To do this, we make use of the following trigonometry ratio
[tex]\cot (\frac{\pi}{2}+\theta)= -\tan (\theta)[/tex]
Substitute 45 for [tex]\theta[/tex].
So, we have:
[tex]\cot (\frac{\pi}{2}+45)= -\tan (45)[/tex]
In trigonometry, [tex]\frac{\pi}{2} = 90[/tex].
So, we have:
[tex]\cot (90+45)= -\tan (45)[/tex]
Add 90 and 45
[tex]\cot (135)= -\tan (45)[/tex]
Also, we have:
[tex]\tan (-45)= -\tan (45)[/tex]
So, the equation becomes
[tex]\cot (135)= \tan (-45)[/tex]
Rewrite as:
[tex]\tan (-45) = \cot (135)[/tex]
Hence, the equivalent expression of tan(-45) is cot(135)

Subtract 7x from both sides:

Divide both sides by -4:

What is the value of k for which the following equation has one solution?
|14+ 7x| - 15 = k
Answer:
7x-1
Step-by-step explanation:
14 + 7x - 15 = k
7x - 1 = k
Finding x,
14 + 7x - 15 = k
=> 14 + 7x = k + 15
=> 7x = k + 15 - 14
=> x = (k + 1)/7
So, 7 * (k+1)/7 - 1 = k
k + 1 - 1 = k
=> k = k
So the answer is true that 7x - 1

Multiply both sides by 4:

Step-by-step explanation:
Set up the equation

Add like terms
(110+x)/4=30
now multiply both sides by 4
(110+x)/4=30

110+x=120
Now subtract 110 from both sides

The number f of miles a helicopter is from its destination x minutes after takeoff is given by f (x)=40-2x. The number f of miles a commercial jet is from its destination x minutes after takeoff is shown in the graph below.
Answer:
Step-by-step explanation:
Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.
f(x) = 40 - 2x
For x = 0,
f(x) = 40 miles
For f(x) = 0,
0 = 40 - 2x
x = 20 minutes
This shows that helicopter traveled 40 miles in 20 minutes.
Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.
For x = 0,
f(x) = 500 miles
For f(x) = 0,
x = 100 minutes
Commercial jet traveled 500 miles in 100 minutes.
The total distance and time taken for each flight are illustrations of intercepts.
The helicopter traveled 40 miles in 20 minutesThe commercial jet traveled 500 miles in 100 minutesWe have:
[tex]x \to[/tex] minutes
[tex]f(x) \to[/tex] miles
Helicopter
[tex]f(x) = 40 - 2x[/tex]
Set f(x) to 0, to calculate the x-intercept
[tex]0 = 40 - 2x[/tex]
Collect like terms
[tex]2x = 40[/tex]
Divide by 2
[tex]x =20[/tex]
Set x to 0, to calculate the y intercept
[tex]f(x) = 40 - 2x[/tex]
[tex]f(0) = 40 - 2 \times 0[/tex]
[tex]f(0) = 40[/tex]
This means that, the helicopter traveled 40 miles in 20 minutes
Commercial Jet
From the graph, the intercepts are:
[tex](x_1,y_1) = (100,0)[/tex] --- the x-intercept
[tex](x_2,y_2) = (0,500)[/tex] --- the y-intercept
This means that, the commercial jet traveled 500 miles in 100 minutes

1. There are 6 more water glasses than coffee mugs in a cabinet. There are 26 water glasses and coffee mugs in the cabinet, in all. How many coffee mugs are there in the cabinet? Write and solve an equation, where m represents the number of coffee mugs, to solve the problem. 2. The product of a number, x, and six is three less than seven times the difference of the same number, x, and four. Write an equation to represent this statement.
Answer:
10
Step-by-step explanation:
No of coffee mugs = m
No of water glasses = g
g = m + 6
g + m = 26
m + 6 + m = 26
m + m = 26 - 6
2m = 20
2m/2 = 20/2
m = 10

The ticket prices to a museum are $5.00 for adults and $3.00 for students. How much will it cost for a group of 71 students, 3 parents, and 2 teachers to attend the museum?
I think the answer is $238.
71 x $3 = $213
2 + 3 = 5
5 x $5 = $25
$213 + $25 = $238
I hope this helps.
The total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum is $360.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Cost of ticket for adult = $5.00
Cost of ticket for students = $3.00
Now, Total number of students = 71
Number of parents = 3
Number of teachers = 2
So, total adults = 3 + 2 = 5
Thus, Total cost of tickets for students = 71*5 = $355
and, Total cost of tickets for adults = 5*3 = 1$5
Therefore,
Total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum = Total cost of tickets for students + Total cost of tickets for adults
⇒ Total cost of ticket for a group = $355 + $5
⇒ Total cost of ticket for a group = $360
Thus, the total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum is $360.

Add one term to the polynomial expression 14x^19 – 9x^15 + 11x^4 + 5x^2 + 3 to make it into a 22nd degree polynomial.
Answer:
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].
Step-by-step explanation:
A polynomial is a sum of algebraic monomials such that:
[tex]p = \Sigma_{i=0}^{n} c_{i}\cdot x^{i}[/tex]
Where [tex]n[/tex] is the degree of the polynomial and [tex]c_{i}[/tex] is the i-th coefficient of the polynomial. A 22nd degree polynomial has [tex]n = 22[/tex], so that given polynomial must added by a monomial with grade 22. Thus:
If [tex]p = 5\cdot x^{2} + 11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}[/tex] and [tex]q = 12\cdot x^{22}[/tex], then we have:
[tex]p' = p+q[/tex]
[tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex]
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].
