Which of the following could be the equation of the function below? On a coordinate plane, a curve crosses the y-axis at y = 2. It has a maximum at 5 and a minimum at negative 1. It goes through one cycle at pi. y = negative 3 sine (2 (x + pi)) + 2 y = negative 3 sine (x + pi) + 2 y = 3 sine (4 (x minus pi)) + 4 y = 3 sine (2 (x + pi)) + 2

Answers

Answer:

b

Step-by-step explanation:

We want to find a sine function such that:

it has a y-intercept equal to 2.it has a maximum of at 5, and a minimum at -1.it goes through one cycle at pi.

The given options are:

y = -3*sin(2*(x + pi)) + 2 y = -3*sin(x + pi) + 2 y = 3*sin(4*(x - pi)) + 4 y = 3*sin(2*(x + pi)) + 2

Notice that the first information that we have, implies that y must be equal to 2 when x = 0.

Knowing that we can discard the third option which has a y-intercept of 4.

Now the second. Remember that for a general function:

y = A*sin(k*x) + M

Where A is the amplitude and M is the midline, the maximum and minimum are given by:

A + M

-A + M

In all the remaining options we have:

A  = ± 3

M = 2

We can see that with these we get the maximum and minimum of 5 and -1.

Finally, we know that it goes through one cycle at pi.

This means that if f(x) is the function, then:

f(x) = f(x + pi)

Also remember that for a general sine function, we have:

sin(x) = sin(x + 2*pi)

Ok, now let's analyze the options (only the sine part)

1) sin(2*(x + pi)) = sin( 2*x + 2*pi) = sin(2*x)

if we evaluate this in x + pi, we will get:

sin(2*( x + pi + pi)) = sin(2*(x + 2*pi)) = sin( 2*x + 4*pi) = sin(2*x)

So yes, option 1 is a correct option (you also can see that option 4 has the exact same sine part, so that option is also correct.)

2) for the second option the sine part is:

sin(x + pi)

if we evaluate this in x + pi we get:

sin(x + pi + pi) = sin(x + 2*pi) = sin(x)

and we have:

sin(x +pi) ≠ sin(x)

Then this function does not go through one cycle at pi.

We can conclude that the two options that meet all the conditions are the first one and fourth one:

1) y = -3*sin(2*(x + pi)) + 2

4) y = 3*sin(2*(x + pi)) + 2

We can't say which one is correct if we do not look at the graph.

If the function starts increasing, then (2) is the correct one, if the graph starts decreasing, then (1) is the correct one.

Below, you can see a graph of both functions:

The green one is y = 3*sin(2*(x + pi)) + 2,  the blue one is y = -3*sin(2*(x + pi)) + 2

Answers

Answer:

Interval for the function has local minimum of 0 is [2,4].

Step-by-step explanation:

You need to find the local minimum of 0 in the given function's graph.

In mathematics, local minimum is a point on a graph whose value is less than all other points near it.

See that, graph value 0 is lie on the x = 3 and in interval x = 2 to x = 4

So, final answer is :

Interval for the function has local minimum of 0 is [2,4].That's the final answer.

For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = 4?
One-eighth
One-half
2
32

Answers

Answer:

2

Step-by-step explanation:

The equation is p = 8/v.

If p = 4, then p = 4 = 8/v

Inverting both sides, we get  

                           1/4 = v/8

Multiplying both sides by 8, we get:

                              2 = v

If the value of p is 4, then the value of V will be 2. Then the correct option is C.

What is the solution of the equation?

The solution of the equation means the value of the unknown or variable.

The equation is given below.

p = 8/V

If the value of p is 4, then the value of V will be

4 = 8 / V

V = 8 / 4

V = 2

Then the correct option is C.

A straight line is drawn through the intersection of the two diagonals of a parallelogram. Prove that it exactly divides the parallelogram into two equal parts by area.

Answers

Answer:

Area of rectangle APQB = Area of rectangle DPQC

Where:

PQ is the line passing through the intersection of the diagonals of the parallelogram ABCD

Step-by-step explanation:

Here we note that a parallelogram is a quadrilateral with the two opposite sides equal, therefore, the diagonals each divides the parallelogram

Given the parallelogram ABCD with a point of intersection of the two diagonals = O

We are to prove that a line PQ passing through O divides the parallelogram into two equal parts;

The diagonals of a parallelogram bisect each other hence

OA = OC and OB = OD

Also ∠AOB = ∠COD (vertically opposite angles at the crossing of the diagonals)

∴ ΔAOB ≅ ΔCOD (SAS congruence rule)

Area of ΔAOB = Area of ΔCOD

In ΔAOP and ΔCOQ, we have;

∠PAO = ∠QCO (alternate interior angles of a parallel line)

OA = OC (as above)

∠AOP = ∠QOC (vertically opposite angles at the crossing of the diagonals)

∴ ΔAOP ≅ ΔQOC

Area of ΔAOP = Area of ΔQOC

From which we have by similarity;

ΔBOQ ≅ ΔPOD

Area of ΔBOQ = Area of  ΔPOD

Hence area of rectangle APQB = Area of ΔQOC + Area of ΔCOD + Area of  ΔPOD = Area of ΔAOP + Area of ΔAOB + Area of ΔBOQ

∴ Area of rectangle APQB = Area of rectangle DPQC there proved as required.

Find the area of the irregular figure. Round your answer to the nearest hundredth if necessary.

Answers

Answer:

Step-by-step explanation:

Area of the figure = Area of semicircle + area of rectangle

Area of semicircle:

d = 14 mm

r = 14/2 = 7 mm

Area = (1/2)πr²

[tex]=\frac{1}{2}*\frac{22}{7}*7*7\\[/tex]

=11 *7

= 77 mm²

Area of rectangle:

length = 14 mm

Width = 10 mm

Area = length *width

       = 14 * 10

       = 140 mm²

Area of the figure = 77 + 140 = 217 mm²

Triangle A″B″C″ is formed by a reflection over x = −1 and dilation by a scale factor of 4 from the origin. Which equation shows the correct relationship between ΔABC and ΔA″B″C″?

Answers

Answer:

[tex]\frac{AB}{A''B''} = \frac{1}{4}[/tex]

Step-by-step explanation:

Given the information:

A'B'C' reflection over x = −1dilation by a scale factor of 4 from the origin

<=> the two triangles are similar to each other, triangles are similar if they have the same shape, but can be different sizes, so  A″B″C″ is 4 time bigger than ABC

=> the relationship between ΔABC and ΔA″B″C″

= [tex]\frac{AB}{A''B''} = \frac{1}{4}[/tex]

We choose C.
