I have a question regarding trignometry
How does Sin(180°-θ) = Sinθ
and how does Cos(180°-θ) = -Cosθ
Step-by-step explanation:
If A is acute, cos (180 - A) = - cos A (because the coordinates would be in 2nd quadrant)
If A is right angle, cos (180 - 90) = cos 90 = 0
(because the coordinates would be on y-axis)
If A is obtuse, cos (180 - A) = + cos A (because the coordinates would be in 1st quadrant)

Given the diagram below, find the value of MQR.
Answer:
The answer is MQR= 48 degrees
Step-by-step explanation:
I got this answer from process of elimination. The first option was 48 degrees so I divided 48 by 3 and got 16 then I applied to (2x + 16): (2(16)+16) and got 48 which comfirmed my answer. Also I took the test and it was right so I know its correct.
The state fair is a popular field trip destination. This year the senior class at High School Aandthe senior class at High School B both planned trips there. The senior class at High School Arented and filled 9 vans and 7 buses with 457 students. High School B rented and filled 11vansand 7 buses with 473 students. Each van and each bus carried the same number of students. How many students can a van carry? How many students can a bus carry? A) Van: 55, Bus: 8 B) Van: 8, Bus: 55
C) Van: 12, Bus: 38 D) Van: 10, Bus: 71
Answer:
B
Step-by-step explanation:
v = how many students fit into a van
b = how many students fit into a bus
School A:
9v+7b=457 (1)
School B:
11v+7b=473 (2)
(1)&(2) => v=8

Solve the problem.The world population of a certain species is evaluated at 5.1× 1010. By some projections, this population will be 3 times more important in 30 years. Express the population at that time in scientific notation.
Large population can be represented in scientific notations
The population in 30 years time is 1.53 * 10^11
The current population is given as:
[tex]\mathbf{Population = 5.1 \times 10^{10}}[/tex]
In 30 years time, the population would be 3 times more.
This means that, the population in 30 years time is: 3 multiplied by the current population.
So, we have:
[tex]\mathbf{New = 3 \times Population}[/tex]
So, we have:
[tex]\mathbf{New = 3 \times 5.1 \times 10^{10}}[/tex]
Multiply
[tex]\mathbf{New = 15.3 \times 10^{10}}[/tex]
Rewrite as:
[tex]\mathbf{New = 1.53 \times 10^{11}}[/tex]
Hence, the population in 30 years time is 1.53 * 10^11

Answer:
Is this the question [tex]x^{2}[/tex]+3x+3=−2x−3
Step-by-step explanation:
[tex]x^{2}[/tex]+3x+3=−2x−3
Step 1: Subtract -2x-3 from both sides.
[tex]x^{2}[/tex]+3x+3−(−2x−3)=−2x−3−(−2x−3)
[tex]x^{2}[/tex]+5x+6=0

Answer:
[tex]\boxed{y = -\dfrac{10}{3}x - 23}[/tex]
Step-by-step explanation:
Equation of a straight line: y = kx + b
Points: (-9,7) and (-6,-3)
Сompose the system of equations:
[tex]\displaystyle \left \{ {{7=-9k + b} \atop {-3=-6k + b}} \right[/tex] [tex]\displaystyle \left \{ {{b= 7 + 9k} \atop {b=6k - 3}} \right \Longrightarrow 7 + 9k = 6k - 3[/tex]
[tex]7 + 9k = 6k - 3[/tex]
[tex]3k = -10|:3[/tex]

Answer:
(x, y) = (19/35, 52/7)
Step-by-step explanation:
When you have an expression for one of the variables, the "substitution" method of solution is a reasonable choice. Here, we have an expression for y that can be substituted into the second equation.
-5x +4(10x +2) = 27
35x +8 = 27 . . . . . . . simplify
35x = 19 . . . . . . . subtract 8
x = 19/35 . . . . divide by the coefficient of x
y = 10(19/35) +2 = 52/7
The solution is (x, y) = (19/35, 52/7).

K(x) k(-3) 2x^2-5x+3
Answer:
When k(x) is 2x² - 5x + 3, k(-3) = 36.
Step-by-step explanation:
k(x) = 2x² - 5x + 3
Substitute the input of x.
k(-3) = 2(-3)² - 5(-3) + 3
Square -3.
k(-3) = 2(9) - 5(-3) + 3
Multiply 2 and 9.
k(-3) = 18 - 5(-3) + 3
Multiply -5 and -3.
k(-3) = 18 + 15 + 3
Add 18 and 15.
k(-3) = 33 + 3
Add 33 and 3.
k(-3) = 36.
