Answer:

amplitude= 2

Step-by-step explanation:

The amplitude of this sine wave is 2 denoted by the coefficient -2 in front of the sin(x).  The negative of the coefficient denotes that the sine wave is the opposite of the standard sine wave.

Answer:

Solve for x: x = 4 - 4y/3

Solve for y: y = 3 - 3x/4

X intercept(s): (4, 0)

Y intercept(s): (0, 3)

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

Answer:

  a) x = (√5 -1)/2 ≈ 0.618034

  b) 1/x = (√5 +1)/2 ≈ 1.618034

Step-by-step explanation:

Given:

  x/(1 -x) = 1/x

Find:

  Exactly, and as a decimal approximation, ...

  a) x, using the quadratic formula

  b) 1/x

Solution:

a) We can multiply the given equation by x(1 -x) to obtain ...

  x² = 1 -x

  x² +x -1 = 0 . . . . . . add x-1

The coefficients for use in the quadratic formula are a=1, b=1, c=-1. The solution using the quadratic formula is ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-1\pm\sqrt{1^2-4\cdot1\cdot(-1)}}{2\cdot1}=\dfrac{-1\pm\sqrt{5}}{2}[/tex]

We are only interested in the positive solution, which is ...

  [tex]\boxed{x=\dfrac{\sqrt{5}-1}{2}\approx0.618034}[/tex]

__

b) The quadratic we developed in the first part can be rearranged like this:

  x² +x = 1 . . . . . . add 1 to both sides

  x(x +1) = 1 . . . . . factor out x

  x +1 = 1/x . . . . . .divide by x

Then to find the value of 1/x, we simply need to add 1 to the value of x we have:

  [tex]\dfrac{1}{x}=\dfrac{\sqrt{5}-1}{2}+1=\dfrac{\sqrt{5}-1}{2}+\dfrac{2}{2}=\dfrac{\sqrt{5}-1+2}{2}\\\\\boxed{\dfrac{1}{x}=\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]

Answer:

  see attached.

Step-by-step explanation:

Your graph demonstrates a possible function, but it has the domain and range swapped.

__

The domain is the horizontal extent, so your line must end at x=-9 on the left and x=6 on the right.

The range is the vertical extent, so the function must extend from -4 at the bottom to +8 at the top.

The attachment shows a linear function with those characteristics.

3000

Step-by-step explanation:

when you multiply by a ten (10, 100, 1000, etc.), just add a zero for each zero. it's the same when you divide: for every zero in the ten, you remove a zero.

Answer:

2

Step-by-step explanation:

mn + p = m + 3n, n = 4 and p = 6

m(4)+6=m+3(4)

4m+6=m+12

4m=m+6

3m=6

m=2

Answer:

B) 2

Step-by-step explanation:

Step 1: Plug in the values of n and p.

Step 2: Subtract m from both sides.

Step 3: Subtract 6 from both sides.

Step 4: Divide both sides by 3.

Step 5: Check if solution is correct.

Therefore, the answer is B) 2.

Expressions can be simplified by breaking it down into several sub expressions.

The equivalent expressions are: [tex]\mathbf{10s= 2 \times 5s }[/tex] or [tex]\mathbf{10s= 5s \times 2}[/tex] or [tex]\mathbf{10s= 5s + 5s}[/tex]

The original expression is:

[tex]\mathbf{Expression = 10s}[/tex]

Express 10s as 5s + 5s

[tex]\mathbf{10s= 5s + 5s}[/tex]

Apply distributive property

[tex]\mathbf{10s= 5s(1 + 1)}[/tex]

Add 1 + 1

[tex]\mathbf{10s= 5s \times 2}[/tex]

Rewrite as:

[tex]\mathbf{10s= 2 \times 5s }[/tex]

Hence, the equivalent expressions are: [tex]\mathbf{10s= 2 \times 5s }[/tex] or [tex]\mathbf{10s= 5s \times 2}[/tex] or [tex]\mathbf{10s= 5s + 5s}[/tex]

discontinuity.

Reasons:

The process and steps to determine the lamp that has burned out;

The given arrangement of the bubs = Series arrangement

Therefore;

A burn out of a bulb, causes a discontinuity by opening the circuit and to current flow.

The meter to use is that determine the defective lamp is one that checks for discontinuity, or an open circuit, which is the presence of infinite resistance, which requires a resistance meter;
