Answer:
Step-by-step explanation:
[tex]\sf f(x) = \dfrac{1}{Sin \ x}[/tex]
f(x) does not contain values where sin x = 0. Sin x is 0 at integral multiples of π.
Domain = R - nπ , n is integers.
The range of Sin x is [-1 , 1] and in this range we cannot find 1/sin x .
Range = (-∞, -1] U [1,∞)
[tex]\sf f(x) =\dfrac{1}{Cos x}[/tex]
f(x) does not contain values where Cos x = 0 . Cos x is 0 at integral of multiples of (π/2)
[tex]\sf Domiain =R -\dfrac{(2n+1)\pi }{2}[/tex]
The range of Cos x is [-1,1] and in this range we cannot find 1/Cos x.
Range = (-∞, -1] U [1,∞)

the inner and outer triangles are similar ( AA postulate )
Then the ratios of corresponding sides are in proportion, that is
[tex]\frac{56}{56+24}[/tex] = [tex]\frac{105}{105+?}[/tex] , that is
[tex]\frac{56}{80}[/tex] = [tex]\frac{105}{105+?}[/tex] ( divide numerator/denominator by 8 to simplify left side )
[tex]\frac{7}{10}[/tex] = [tex]\frac{105}{105+?}[/tex] ( cross- multiply )
7(105 + ? ) = 1050 ← distribute parenthesis on left side

Step-by-step explanation:
what does 160=7x+6 equal to?
Answer:
x=22
Step-by-step explanation:
7x+6=160.
Lets start by moving 6 over to the other side. We can do this by subtracting 6 from both sides of the equation.
7x+6-6=160-6
7x=154
Now, let's isolate x by getting rid of the 7. The 7 is being multiplied with x, so to get rid of it we have to divide both sides by 7.
7x/7 = 154/7
x=22
Look Below :
Step-by-step explanation:
160 - 6 = 7x
154 = 7x
Or
7x = 154
x = 22

Solve for p and k. For 50 POINTS!!
Answer:
P = 55°
K = 27°
Step-by-step explanation:
55° + 98° + c = 180°
153° + c = 180°
c = 27°
since C is opposite K, K = 27°
Since 55° is opposite P, P = 55°
We can check this by adding up the values of P, K, and 98
27°+55°+98° = 180°
32 less than 3/7 of a number is 11/35 of that number. Find the number.
Answer:
Step-by-step explanation:
Let "a number" be x.
"3/7 of a number" means (3/7)x
"32 less" means - 32
Thus, "32 less than 3/7 of a number" means (3/7)x -32
"is 11/35 of that number" means = (11/35)x
Put these together and we get:
(3/7)x -32 = (11/35)x
(3/7)x - (11/35)x = 32 Rearrang to get the x on one side
We need to change "(3/7)x - (11/35)" so that the two terms have a common denominator.
If we multiply the first term by (5/5) [which is equal to 1], we get:
(5/5)(3/7)x or
(15/35)x
We can now write:
(15/35)x - (11/35)x = 32
(4/35)x = 32
Multiply both sides by (35/4)
(35/4)(4/35)x = (35/4)(32)
x = (35)(8)
x = 280

We need to find the value of x
so first
Tan 60 = Perpendicular / 11√6
Perpendicular = 1.732 (11√6)
Perpendicular = 46.66
Then,
Sin 45 = Perpendicular / x
Sin 45 = 46.66/ x

2. Given the equation of a line, y = 1/5x, the slope is:
Answer:
1/5
Step-by-step explanation:
The slope-intercept form looks like [tex]y=mx+b[/tex] where b is the y-intercept and m is the slope. m is the slope because if you increase x by 1, the value y increases by m, and if you increase x by 1 again, the y-value will increase by the value of m, because it's being multiplied. b is the y-intercept since the y-intercept is when x=0 so mx will become m(0) which is just 0 leaving b by it self. In this case you have y=1/5x so if you were to start with 0 as x the value of y is 0. Now increase it by 1 so x becomes 1, the value of y becomes 1/5x, now increase it by 1 again so x becomes 2, the value of y is 2/5x, so as you can see the function is just increasing by 1/5 so that's the slope, so essentially whatever the coefficient of x is (the number in front of the variable x), is the slope

-------------------------------------------------------------------------------------------------------------
Given: [tex]\textsf{y = 1/5x}[/tex]
Find: [tex]\textsf{The slope of the line}[/tex]
Solution: In order to determine the slope of the line we need to see how the slope-intercept form compares to this expressions. The slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. In this case we have no y-intercept therefore we do not have a b. However, our slope is equal to 1/5 as it fits perfectly with the form that was provided.

A pencil cost $1.20 and a pen cost $2.90. Jasmiah bought an equal number of such pencils and pens. She spent $32.30 more on the pens than on the pencils. How many pencils and pens did she buy altogether?
Answer:
38
Step-by-step explanation:
Let x be the number of pencils bought.
Let y be the number of pens bought.
Given information from the question:
x = y - equation 1
2.9y - 1.2x = 32.30 - equation 2
From here we can use the substitution method in solving simultaneous equations to find x and y. We will substitute equation 1 into equation 2.
2.9y - 1.2y = 32.30
1.7y = 32.30
y = [tex]\frac{32.3}{1.7} \\= 19[/tex]
Now since we know number of pens = number of pencils,
x = 19
Total Pencils and Pens bought = x + y = 19 + 19 = 38

Jorge will receive 9 hours in time off from work.
How many hours will Jorge get to take time off?
It is given that, Jorge has done overtime for 6 hours in this week. As per the Fair Labor Standards Act, for 6 hours of overtime work, he must be paid one and a half times the pay he gets per hour.
Instead of receiving an overtime pay for working 6 hours extra, Jorge decides to receive paid leaves from work, that is, he will get one and a half of the total hours for which he worked overtime.
As a result, the time off he receives from work = [tex]1\frac{1}{2} (6)[/tex] hours
[tex]=\frac{3}{2}(6) = 9 hours[/tex]
Thus, Jorge gets 9 hours in time off from work in return. The time that he earns for the overtime is equivalent to the pay he was supposed to receive for the overtime work.

The sum of two numbers is 8 and sum of their reciprocal is 8/15. Find the numbers.
Answer:
The 2 numbers are 3 and 5.
Step-by-step explanation:
x + y = 8
1/x + 1/y = 8/15
From first equation y = 8 - x so
1/x + 1 / (8-x) = 8/15
Multiply through by the LCM 15x(8-x):-
15(8 - x) + 15x = 8x(8-x)
120 - 15x + 15x = 64x - 8x^2
8x^2 - 64x + 120 = 0
x^2 - 8x + 15 = 0
(x - 3)(x - 5) = 0
x = 3 or 5
so y = 8-3 = 5 or 3.
