All real numbers except 13.
All real numbers except -16 and 16.
All real numbers except -13 and 13.
All real numbers except 16.
Answer:
Step-by-step explanation:
Domain is the set of all values of x where the function is defined. For this function the only limitation upon x exists when the denominator would equal zero, because division by zero is undefined. So the denominator 13-x cannot equal zero thus x cannot equal 13. Thus the domain is all real numbers except 13.

besties help what's 84÷n=6
Answer:
14
Step-by-step explanation:
When one encounters a problem like this all one must do is divide the number to the left (84) by the number on the right (6) then to double check divide the outcome by the number on the left or multiply the outcome by the one on the right.
Feel free to check the equations below:
84 divided by 6 = 14
84 divided by 14 = 6
14 times 6 = 84
84 ÷ 14 = 6
A (5,3) and B(3,-2) are two fixed points. Find the equation of the locus of P, so that the
area of triangle PAB is 9.
Answer:
[tex]37=5x-2y,\,1=5x-2y[/tex]
Step-by-step explanation:
If [tex](x_1,y_1),\,(x_2,y_2),\,(x_3,y_3)[/tex] are coordinates of a triangle then area of a triangle is equal to [tex]\frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]
Let point P be [tex](x,y)[/tex]
Put [tex](x_1,y_1)=(5,3),\,(x_2,y_2)=(3,-2),\,(x_3,y_3)=(x,y)[/tex]
Area of a triangle = [tex]\frac{1}{2}|5(-2-y)+3(y-3)+x(3+2)|[/tex]
[tex]=\frac{1}{2}|-10-5y+3y-9+5x|\\\\=\frac{1}{2}|-19+5x-2y|[/tex]
Also,
Area of a triangle = 9 square units
[tex]9=\frac{1}{2}|-19+5x-2y|\\\\18=|-19+5x-2y|[/tex]
±18 = -19 + 5x - 2y
[tex]18=-19+5x-2y,\,-18=-19+5x-2y\\\\37=5x-2y,\,1=5x-2y[/tex]

The Venn diagram below choices of subject by 40 student.18 chose chemistry ,20 chose physics and 15 chose biology ,2 chose chemistry only,8 chose physics only and 1 chose biology only, 4 chose all students.find the number of students who chose none of the three students.
Answer:
10
Step-by-step explanation:
Given that:
Let :
C = chemistry
B = biology
P = physics
n(C) = 18
n(P) = 20
n(B) = 15
C only = 2
P only = 8
B only = 1
All 3 subjects = 4
P n B only = 20 - (8 + x + 4) = 8 - x
C n B only = 18 - (2 + x + 4) = 12 - x
B = (12 - x) + 4 + 1 + (8 - x) = 15
B = 25 - 2x = 15
B = 10= 2x
x = 5
PnC only, x = 5
Number who chose none of the 3 subjects, k equals :
2 + x + 8 + 4 + 1 + (8 - x) + (12 - x) + n = 40
35 - 3x + n = 40
x = 5
35 - 15 + y = 40
20 + n = 40
n = 40 - 20
n = 10

Answer:
A= 236.7 ft²
Step-by-step explanation:
Split into a circle and rectangle to find the areas separately and add them.
A = πr²
d= 15
r= 15/2
A= π(15/2)² ≈176.7
A= lw
A= (15)(4) = 60
A= 176.7 + 60
A= 236.7 ft²

If there are 42 boys and 54 girls in a room, fill out all of the possible
ratios of boys to girls that could be made.
There are 42 boys for every 54 girls (42:54 ratio)
Answer:
21:27 and 14:18
Step-by-step explanation:
We can solve this by using common factors
one of the common factors of 54 and 42 is 3
42/3=14
54/3=18
so one of the ratios is 14:18
another common factor is 2
42/2=21
54/2=27
so another ratio is 21:27

d. tan (35) = [tex]\frac{x}{10}[/tex]
Step-by-step explanation:
You must memorize the definitions of all the trig functions.
Tan of an angle = opposite side/adjacent side
In your case, the opposite side of the 35° angle is x and the adjacent side of the 35° angle is 10
So, tan 35 = x/10
