Answers
Answer:
-i.
Step-by-step explanation:
Applying DeMoivre' s theorem:
(sin 30 + i cos 30)^18
= sin(18*30) + i cos(18*30)
= sin 540 + i cos 540
= sin (3*180) + i cos (3*180)
= 0 + -1 * i
= -i.

A line is perpendicular to y=-2x+5 and intersects the point (-4,2) what is the equation of this perpendicular line
Answers
Answer:
2y - x = 8
Step-by-step explanation:
First get the slope of the line given
y=-2x+5
From the line, slope m = -2
The slope of the required line M = -1/-2 = 1/2
Substitute the point (-4, 2) and m = 1/2 into the point slope equation;
y - y0 = m(x-x0)
y - 2 = 1/2(x+4)
2(y-2) = x+ 4
2y - 4 = x+4
2y - x = 4+4
2y - x = 8
Hence the equation of this perpendicular line is 2y - x = 8

positivenegativedecreasingincreasingStep-by-step explanation:
1. These are intervals where the graph is above the x-axis, hence positive.
2. These are intervals where the graph is below the x-axis, hence negative.
3. The first interval is between the left peak and the valley, where the graph is decreasing. The second interval is right of the right peak, where the graph is also decreasing.
4. The first interval is left of the left peak, where the graph is increasing. The second interval is between the valley and the right peak, where the graph is also increasing.

Can you guys help me with this question.
Answers
Answer:
y=2x
Step-by-step explanation:
The equation equals the change in Y over the change of X. If you notice on the table, the x value increases by a unit of 1, and the y value increases by a unit of 2. If you put those two units into the equation of the change in Y/the change of X you will get 2/1=2. The slope is 2. Now plug in the two into y=mx+b form and you will get y=2x. You can check this by taking any y value on the table, multiplying it by 2, and verifying that the value matches the corresponding Y value.

For which system of equations is the graph below a solution?
Answers
The equation of Graph shown is y= x- 2 and y= -x+ 3.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given;
We have the graph whose intersecting point is (2.5, 0.5).
Now, we put the values of x and y in the questions.
1. y= x+ 2 and y= -x+ 3
Solving the equation we get
x= 0.5 and y= 2.5
2. y= x- 2 and y= -x+ 3
Solving the equation we get
x= 2.5 and y= 0.5
3. y= x- 2 and y= -x - 3
Solving the equation we get
x= -0.5 and y= -2.5
4. y= x + 2 and y= -x - 3
Solving the equation we get
x= -2.5 and y= -0.5

One way to find the solution is to take the area of
bigest rectangle ( z+z+8)*(z+4+6)
and subtract the two small rectangles
(z*(14-10)) and
