The graph of y=3x^4-16x^3+24x^2+48 is concave down for x values greater than or equal to 0.

The graph of y=3x^4-16x^3+24x^2+48 is an example of a polynomial function. To determine the concavity of a polynomial function, we must first identify the intervals where the function is increasing and decreasing. In this case, the function is increasing for all x values greater than or equal to 0.

Next, we must find the second derivative and determine the intervals where the second derivative is negative. If the second derivative is negative, then the graph is concave down. For this polynomial, the second derivative is y'' = -48x + 48, which is negative for all x values greater than or equal to 0. This means that the graph of y=3x^4-16x^3+24x^2+48 is concave down for all x values greater than or equal to 0.

Janet should multiply both sides of the equation by the denominator of the fraction to eliminate the fraction on the right side,

To solve this equation, Janet needs to find the value of "y" that makes the equation true. In order to do this, she needs to get all of the terms with "y" on one side of the equation and all of the constants on the other side.

One way to do this would be to multiply both sides of the equation by the denominator of the fraction on the right side. This will eliminate the fraction on the right side and give Janet an equation with only one term on each side. The denominator of the fraction on the right side is (y+1), so Janet should multiply both sides of the equation by (y+1).

This will give her the equation:

(y+1)(y+startfraction y squared minus 5 over y squared minus 1 end fraction) = (y+1)(start fraction y squared + y + 2 over y + 1 end fraction)

Multiplying out the terms on each side will give Janet a polynomial equation in "y" that she can solve using standard techniques.

The trigonometric identity 1 - sin²θ/(1 + cosθ) = cosθ is true since L.H.S = R.H.S

Trigonometric identities are equations that shows the relationship between trigonometric ratios.

Given the trigonometric identity

1 - sin²θ/(1 + cosθ) = cosθ

We need to show that the left hand side (L.H.S) equals the right hand side (R.H.S) of the equation

So, we proceed as follows

Given that

1 - sin²θ/(1 + cosθ) = cosθ

Starting with the left hand side

L.H. S = 1 - sin²θ/(1 + cosθ)

Taking the L.C.M, we have that

[(1 + cosθ)  - sin²θ]/(1 + cosθ) = [1 + cosθ  - sin²θ]/(1 + cosθ)

Using the trigonometric identity sin²θ + cos²θ = 1

Substituting this into the equation, we have that

[1 + cosθ  - sin²θ]/(1 + cosθ) =  [sin²θ + cos²θ + cosθ  - sin²θ]/(1 + cosθ)

= [cos²θ + cosθ + sin²θ - sin²θ]/(1 + cosθ)

= [cos²θ + cosθ + 0]/(1 + cosθ)

= [cos²θ + cosθ]/(1 + cosθ)

Factorizing out cosθ from the numerator, we have that

= [cos²θ + cosθ]/(1 + cosθ) = cosθ(cosθ + 1)/(1 + cosθ)

= cosθ(1 + cosθ)/(1 + cosθ)

= cosθ

= R.H.S

So, 1 - sin²θ/(1 + cosθ) = cosθ

Answer:

= cos θ

Step-by-step explanation:

A trigonometric identity that we already know is

[tex]\sin {}^{2} \theta + \cos {}^{2} \theta = 1[/tex]

From the question given we want to prove that the left side equals the right side:

[tex]1 + \frac{\sin {}^{2} \theta }{1 + \cos \theta }[/tex]

Let's rewrite sin²θ using the identity sin²θ+cos²θ=1 by subtracting cos²θ:

sin²θ=1-cos²θ, so we can write 1-cos²θ in place of sin²θ to give:

[tex]1 - \frac{1 - \cos {}^{2}\theta }{1 + \cos \theta }[/tex]

Now that everything is in terms of cos, we can solve this fraction.

1-cos²θ can be written as a difference of two squares which is (1+cosθ)(1-cosθ):

[tex]1- \frac{(1+cos \theta)(1-cos \theta)}{1+cos \theta}[/tex]

We can cancel out 1+cosθ from the fraction to give:

[tex]1 - (1 - cos \theta)[/tex]

Expand the brackets out:

[tex]= 1 - 1 + cos \theta[/tex]

The midpoint of the line segment is (4, -3).

The slope of the line segment is -2/5.

The equation of the perpendicular bisector is y = 5/2x - 13.

To find the equation of the perpendicular bisector of a line segment, we need to determine two things:

The midpoint of the line segment and the slope of the perpendicular bisector.

Midpoint:

The midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂) is given by the formula:

[(x₁ + x₂) / 2, (y₁ + y₂) / 2]

Using the endpoints (-1, -1) and (9, -5), we can find the midpoint:

x = (-1 + 9) / 2 = 4

y = (-1 - 5) / 2 = -3

Slope:

The slope of the line segment with endpoints (x₁, y₁) and (x₂, y₂) is given by the formula:

m = (y₂ - y₁) / (x₂ - x₁)

Using the endpoints (-1, -1) and (9, -5), we can find the slope:

m = (-5 - (-1)) / (9 - (-1))

= (-5 + 1) / (9 + 1)

= -4 / 10

= -2 / 5

Perpendicular Bisector:

The slope of the perpendicular bisector will be the negative reciprocal of the slope of the line segment.

The slope of the perpendicular bisector will be 5/2.

Using the midpoint (4, -3) and the slope 5/2, we can find the equation of the perpendicular bisector using the point-slope form:

y - y₁ = m(x - x₁)

Plugging in the values, we have:

y - (-3) = 5/2(x - 4)

y + 3 = 5/2(x - 4)

y + 3 = 5/2x - 10

Mixed Number: 4 9/20
Decimal Form: 4.45

If this help please set brainliest.

Explanation:
To add these fractions, we first need to find a common denominator. 4 and 5 have a common multiple of 20, so we can express each fraction using a denominator of 20:

-4/5 = (-8)/20

5 1/4 = 21/4 = (215)/(45) = 105/20

Now we can add the fractions:

(-8)/20 + 105/20 = (105 - 8)/20 = 97/20

To express the result as a mixed number, we can divide 97 by 20 to get the integer part, which is 4 with a remainder of 17. The fraction part is 17/20, which can be simplified to 9/20 by dividing both the numerator and denominator by 8. The final result is:

4 9/20

This fraction can be simplified to 4.45 by dividing both the numerator and denominator by 5:

4 9/20 = (4*4 + 9)/(20/5) = (16 + 9)/4 = 25/4 = 6.25/1 = 6.25

So the final result is 4.45.
