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)
PLEASE HELP ME OUT!!!!!!!!!!
Answer:
Exponential
Step-by-step explanation:
- Linear is a straight line no matter what.
- Quadratic lines makes a u or v shape that opens up, down, left, or right.
- Exponential is like a slanted 45° clockwise u and a bit stretched horizontally.
- Square root lines on a graph, looks more like a slanted L 90° clockwise.
- Inverse Variation would show its inverse, same as a mirror, it would be something similar to a hyperbola.

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
Step 2: Factor left side of equation.
(x+2)(x+3)=0
Step 3: Set factors equal to 0.
x+2=0 or x+3=0
x=−2 or x=−3The 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
b=55

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

For Thanksgiving dinner, Josie purchased three cans of cranberry sauce that cost $0.78 each. She gave the cashier $10.00. How much change did she get back?
Answer:
$7.66
Step-by-step explanation:
[tex]0.78 \times 3 = 2.34[/tex]
[tex]10.00 - 2.34 = 7.66[/tex]
Answer:
$7.66
Step-by-step explanation:
1. Multiply $0.78 x 3. (you should get $2.34)
2. Subtract $10.00 from $2.34
Your final answer should be $7.66

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.
{y=10x+2
-5x+4y=-27
this is systems of equations
[tex]y = 10x +2~~....(i) \\\\-5x +4y = -27~~....(ii)\\\\\text{Substitute y =10x+2 in equation (ii):}\\\\\\-5x +4(10x+2) = -27 \\\\\implies -5x + 40x + 8 +27 =0\\\\\implies 35x +35=0\\\\\implies 35(x +1) =0\\\\\implies x +1 = 0 \implies x = -1\\\\\text{Substitute} ~x =-1 ~ \text{in equation (i):}\\\\y = 10(-1) +2 = -10+2 = -8 \\\\\\\text{Hence}~ (x,y) = (-1,-8)[/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.
