Answer: This is a trig relationship from one of our special triangles, the 30-60-90 triangle.
Tan x = the opposite side of angle x divided by the adjacent side of angle x
The tangent is √3 when x = 60° or π/3
However, in this problem the value of the tangent is negative. In which of the four quadrants is the tangent function negative?
This function is negative in the second and fourth quadrants or when x = 120 and 300 degrees (or 2pi/3 and 5pi/3)
***I am assuming that the negative sign should be outside of the square root sign***
w x and y are three integers w is 2 less than x y is 2 more than x prove that wy+ 4 =x^2
w + 2 = x
x + 2 = y
Cross multiply
y(w+2) = x(x+2)
wy + 2y = x^2 + 2x
make x the subject of the equation
x = y - 2
substitute this in place of (x) in 2x
wy + 2y = x^2 + 2(y-2)
wy + 2y = x^2 + 2y - 4
wy + 2y - 2y + 4 = x^2
wy + 4 = x^2

Step-by-step explanation:
Nancy sold tickets to a school play. She sold $426 worth of tickets. She sold 8 more adult tickets than children tickets and 3 times as many senior tickets than children tickets. If children tickets are $3, senior tickets are $4 and adult tickets are $6, how many adult tickets did Nancy sell
Answer:
So number of Adult tickets sold = A = 26.
Step-by-step explanation:
Define A, C, S as
A = number of adult tickets,
C = number of children tickets,
S = number of Senior tickets.
Then, by the statement of the problem, we have that
A = 8 + C,
S = 3C,
3C + 4S + 6A = 426,
so that
3C + 4(3C) + 6(8 + C) = 426
3C + 12C + 48 + 6C = 426
21C + 48 = 426
7C + 16 = 142
7C = 126
C = 126/7 = 18
A = 8 + 18 = 26
S = 3(18) = 54
Adjoa’s gross salary for last month was Ghc4,687.24. If Ghc421.78 was deducted from Adjoa’s salary pay, how much take-home pay did Adjoa earn this past month?
Adjoa’s gross salary for last month was Ghc4,687.24. If Ghc421.78 was deducted from Adjoa’s salary pay, the take-home pay that Adjoa earn in the past month is Ghc4,265.46
The gross salary is the amount received by an individual prior to the deduction of the taxes.
Given that:
Adjoa's gross salary for last month = Ghc4,687.24and Ghc421.78 was deducted from Adjoa's salary pay.Then, the take-home that Adjoa earned in the past month is calculated by removing the amount deducted from her gross salary.
i.e.
= Ghc4687.24 - Ghc421.78
= Ghc4,265.46

hope this helps <3
Answer:
Step-by-step explanation:
x= 50
y+25=180(because it is on a straight line)
y+25=180
y+25=180
y+25-25= 180-25
y+0= 155
y= 155
z+ y=180
z+ 155= 180
z+ 155- 155 =180-155
z+ 0 = 25
z = 25

Given that Cos(A) = .6 and csc(A) is -1.25, what is tan (a)
============================================================
Explanation:
cos(A) = 0.6 = 6/10 = 3/5
Recall that csc is the reciprocal of sine.
If csc(A) = -1.25, then sin(A) = 1/csc(A) = 1/(-1.25) = -0.8 = -8/10 = -4/5
Then we would have
tan(A) = sin(A)/cos(A)
tan(A) = sin(A) ÷ cos(A)
tan(A) = (-4/5) ÷ (3/5)
tan(A) = (-4/5) * (5/3)
tan(A) = -4/3
Answer:
-4/3

a) 45/100, Same or equivalentb) 5/9, Differentc) 9/20, Same or equivalentd) 27/60 = 9/20, Same or equivalentFind f(0) and f(6)
f(x)= x^2+10x+72/x^2-12x+36
Answer:
f(0) = 2 f(5) = 147
Step-by-step explanation:
f(0) = (0²+10·0+72)/(0²-12·0 + 36) Substitute 0 for x and solve.
= 72/36
= 2
f(5) = (5²+10·5+72)/(5²-12·5 + 36) Substitute 5 for x and solve.
= (25 + 50 + 72)/(25 - 60 +36)
= 147/1

Carpenter Chalberg is building a new wall in his house. The wall is 8 feet long and 8 feet tall. The wall will be framed with wood and also have studs (vertical supports) at least every 18 inches. The wall has no doors or windows. He is looking to purchase enough 8 foot boards of wood to make the wall’s frame. How many boards will Carpenter Chalberg need?
9514 1404 393
Answer:
9
Step-by-step explanation:
For studs 16" O.C., Chalberg will need 9: one at the beginning of each of the 16" spaces in the 96" width of the wall, and one at the end. That's a total of 6+1 = 7 studs.
The top and bottom edges of the wall are each 8', so will require 1 more board each.
The total number of boards Chalberg needs is 9.

y=2x+3
Leave your answer in the form y=mx+c
Answer:
y=-1/2x+7/2
Step-by-step explanation:
Gradient is negative reciprocal so -1/2x
3=-1/2x + 7/2
y=-1/2x+7/2
Answer:
perpendicular lines have the same gradient
y=2x+3
The gradient of the two lines is 2
Gradient=change in y/change in x
=y2-y1/x2-x1
Let (x,y) also lie on the line
2= y-3/x-1
2(x-1) =y-3
2x-2=y-3
2x-y=-3+2
2x-y= -1

Let's take the number of cows in the field as 'c'.
Then, the number of horses in the field is = c + 2 [2 more horses than cows]
Total number of animals on the field = 16.
So, equation becomes...
c + c + 2 = 16
2c + 2 = 16
