You add them together and subtract 1 because the total amount stays the same throughout the entire problem and you have to find the amount of water in the glass that is not full when the other glass is full. 10/12 + 8/15 = 50/60 + 32/60 = 82/60. 82/60 - 60/60 = 22/60, which simplifies to 11/30.
Angle θ is in standard position. If (8, -15) is on the terminal ray of angle θ, find the values of the trigonometric functions.
Your question: Angle θ is in standard position. If (8, -15) is on the terminal ray of angle θ, find the values of the trigonometric functions.
Answer:
sin(θ) = -15/17
cos(θ) = 8/17
tan(θ) = -15/8
csc(θ) = -17/15
sec(θ) = 17/8

Answer:
parallel
Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slopes m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 3)
m = [tex]\frac{3-2}{2+1}[/tex] = [tex]\frac{1}{3}[/tex]
Repeat with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1)
m = [tex]\frac{1-0}{3-0}[/tex] = [tex]\frac{1}{3}[/tex]
Since slopes are equal then parallel

3 feet of snow fell in 1 2/3 hours. What was that rate in inches per hours?
1) 1 4/5
2) 9 4/5
3) 1 1/5
4) 9.5
Answer:
21 [tex]\frac{3}{5}[/tex]in/hr
Step-by-step explanation:
Distance of snow fall = 3ft
Time taken = 1[tex]\frac{2}{3}[/tex]hrs
Unknown:
Rate of snowfall = ?
Solution:
The rate of the snowfall is the same as the speed of the fall;
Rate of snowfall = [tex]\frac{distance of snowfall}{time}[/tex]
Convert the ft to inches;
1ft = 12inches
3ft = 3 x 12 = 36inches
Input the parameters and solve;
Rate of snowfall = [tex]\frac{36}{\frac{5}{3} }[/tex] = 36 x [tex]\frac{3}{5}[/tex] = 21 [tex]\frac{3}{5}[/tex]in/hr

(x, y)→(x + 2, x − 4)
(x, y)→(x + 4, x − 2)
(x, y)→(x − 7, y + 7)
(x, y)→(x + 7, y − 7)
Answer:
The answer is B I think.
Answer:
D
Step-by-step explanation:
The reason is because y is rise or how far you go down while x is whether you go right or left. Lets use point D for example if we move 7 to the right x is positive then we lower 7 then y is negative that's why I think it's correct.

An unusually wet spring has caused the size of a mosquito population in some city to increase by 9% each day. If an estimated 200,000 mosquitoes are in the city on May 7 , find how many mosquitoes will inhabit the city on May 21. Use y=200,000(1.09)x where x is number of days since May 7.
On May 21 there will be approximately____nothing mosquitoes.
On May 21 there will be approximately 728,500 nothing mosquitoes.
What is an exponential function?In Mathematics, an exponential function can be modeled by using this mathematical expression:
f(x) = ab^x
Where:
a represents the initial value or y-intercept.x represents time.b represents the rate of change.Based on the information provided above, an exponential function which models the situation is given by:
y = 200,000(1.09)^x
For the time between May 7 and May 21, we have:
Time = May 7 to May 21 = 15 days.
Substituting the given parameters into the exponential function formula, we have;
y = 200,000(1.09)^15
y = 200,000(3.6425)
y = 728,500 mosquitoes.

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions.
Answer:
x=18.5
y=37
Step-by-step explanation:
90+2y+16=180
106+2y=180
2y=74
y=37
16+4x+90=180
106+4x=180
4x=74
x=18.5
Answer:
y = 37, x = 18.5
Step-by-step explanation:
O = 16 because of the vertical angles rule. The degrees on a straight line is 180 degrees. That means that because AB is a straight line, 2y + O + 90 = 180. We also know that CD are straight, so O + 4x +90 = 180.
Now we solve for x and y:
2y + O + 90 = 180
2y + 106= 180
2y = 74
y = 37
O + 4x +90 = 180
16 + 4x +90 = 190
4x + 106 = 180
4x = 74
x = 18.5

Solve the following quadratic by factoring. X2-5x=14
Answer:
x=−2 or x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−5x=14
Step 1: Subtract 14 from both sides.
x2−5x−14=14−14
x2−5x−14=0
Step 2: Factor left side of equation.
(x+2)(x−7)=0
Step 3: Set factors equal to 0.
x+2=0 or x−7=0
x=−2 or x=7

The midpoint of AB is M(3, -1). If the coordinates of A are (5,1), what are the
coordinates of B?
Given parameters:
Midpoint of AB = M(3, -1)
Coordinates of A = (5,1)
Unknown:
Coordinates of B = ?
Solution:
To find the mid point of any line, we use the expression below;
[tex]x_{m} = \frac{x_{1} + x_{2} }{2}[/tex] and [tex]y_{m} = \frac{y_{1} + y_{2} }{2}[/tex]
where [tex]x_{m}[/tex] and [tex]y_{m}[/tex] = coordinates of the mid points = 3 and -1
x₁ = 5 and y₁ = 1
x₂ = ? and y₂ = ?
Now let us input the variables and solve,
3 = [tex]\frac{5 + x_{2} }{2}[/tex] and -1 = [tex]\frac{1 + y_{2} }{2}[/tex]
5 + x₂ = 6 -2 = 1 + y₂
x₂ = 1 y₂ = -2 -1 = -3
The coordinates of B = 1, -3

Point A is the midpoint of side XZ and point B is the midpoint of side YZ. Triangle X Y Z is cut by line segment A B. Point A is the midpoint of side X Z and point B is the midpoint of side Y Z. The length of X Y is 5 x minus 7, the length of A B is x + 1, and the lengths of X A and Z A are 2 x minus 2. The lengths of Y B and B Z are congruent. What is AX? 2 units 4 units 6 units 8 units
Answer:
B. 4unitsStep-by-step explanation:
Find the diagram attached. The diagram is a similar triangle.
From the diagram, XZ/XY = CA/AB
Given XZ = 2x-2+2x-2 = 4x-4
XY =5x-7
CA = 2x-2
AB= x+1
On substituting this parameters into the formula to get x first
4x-4/5x-7 = 2x-2/x+1
cross multiply
(4x-4)(x+1) = 5x-7(2x-2)
open the parenthesis
4x²+4x-4x-4 = 10x²-10x-14x+14
4x²-4 = 10x²-24x+14
10x²-4x²-24x+14+4 = 0
6x²-24x+18 = 0
x²-4x+3 = 0
x²-3x-x+3 = 0
x(x-3)-1(x-3) =0
(x-3)(x-1) = 0
x = 3 and 1
Next is to get length AX.
Given AX = 2x-2
Substitute x = 3 into the expression
AX = 2(3)-2
AX = 6-2
AX = 4 units
Hence the measure of length AX is 4 units

4
