Step-by-step explanation:

To compare fractions, they need to have a common denominator.

The least common denominator of 1/2 and 2/3 is 6.

1/2 = 3/6

2/3 = 4/6

Now find the fraction with the larger numerator.

4/6 > 3/6, so 2/3 > 1/2

Given the function, where a, b, and c are positive numbers:
f(x) = (x - a)(x - b)2(x2 + c)
How many real roots does f(x) have, including multiple roots? |
How many imaginary roots does f(x) have?

Answers

Answer:

2 real roots and 1 imaginary roots

Step-by-step explanation:

f(x) = [tex](x-a)(x-b)^{2} (x^{2}+c)[/tex]

There are only 2 real roots and one imaginary roots.

Separate the equation into sections because the function is a multiplication with no outside sum or substraction:

Real Roots:

[tex](x-a)[/tex] = 0 when x = a

[tex](x-b)^{2}[/tex] = 0 when x = b

Imaginary roots:

[tex](x^{2}-c)[/tex] = 0 when x = [tex]\sqrt{-c}[/tex]

How many pizzas can she make if each pizza needs a given amount of cheese?- the given amount of cheese is 1/5 block of cheese

Answers

she can make 45 pizzas with 9 blocks of cheese. 1/5 is equal to .20 so divide 9 by .20 to get 45
The answer to this question is 45. What you do is you take the amount of cheese it takes to make one pizza and multiply it by 5 to have 1 block of cheese done. Then you multiply that by 9 because you have 9 blocks of cheese. You get 45

Let f be a differentiable function such that f(1)=π2 and f′(x)=3arctan(x2−3x+2). What is the value of f(3) ?

Answers

Answer:

2.899

Step-by-step explanation:

Given that:

[tex]f' (x) =3 tan ^{-1} (x^2 -3x +2)[/tex]

[tex]\text{applying integration on both sides with respect to x}[/tex]

[tex]\int \limits ^{3}_{1}} f'(x) \ dx = \int ^3_1 3tan ^{-1} (x^2 -3x+2) \ dx[/tex]

[tex]f(3)-f(1)= 3 \int ^3_1 3tan ^{-1} (x^2 -3x+2) \ dx[/tex]

[tex]f(3) = \dfrac{\pi}{2}+3\int^{3}_{1} tan^{-1} (x^2 -3x+2)dx ---(1)[/tex]

[tex]\text{consider } \ \ 3\int^{3}_{1} tan^{-1} (x^2 -3x+2)dx[/tex]

[tex]h = \dfrac{b-a}{n}[/tex]

[tex]where; n = 10 , a =1, b= 3[/tex]

[tex]h = \dfrac{3-1}{10}[/tex]

[tex]h = \dfrac{2}{10}[/tex]

[tex]h = 0.2[/tex]

[tex]\text{The value of x and corresponding } y = 3tan^{-1}(x^2-3x+2) \ are:[/tex]

x     1      1.2      1.4      1.6      1.8      2      2.2      2.4      2.6      2.8      3

By simpson's rule:

[tex]\int \limits ^3_1 \ 3 tan^{-1} (x^2-3x+2) dx \simeq \dfrac{h}{3}(y_o+y_{10}) +4(y_1+y_3+y_5+y_7+y_9)+2(y_2+y_4+y_6+y_8)][/tex]

[tex]= 1.32804[/tex]

[tex]\text{From}; f(3) = \dfrac{\pi}{2}+1.32804 \\ \\ f(3) = 2.89883633 \\ \\ \mathbf{f(3) \simeq 2.899}[/tex]

Trapezoidal rule is used to evaluate the area of the curve by using various strips of equal width which is in the form of trapezoids. The value of [tex]f(3)[/tex] is 2.8989.

Given information

In the given problem [tex]f[/tex] is the function such that,

[tex]f(1)=\dfrac{\pi}{2} \\[/tex]

The differentiated function is,

[tex]f'(x)=3\tan^-(x^2-3x+2)[/tex]

Integrate the above equation with respect to the x,

[tex]\int\limits^3_1 {f'(x)} \, dx =\int\limits^3_1 {3\tan^-(x^2-3x+2)} \, dx\\f(3)-f(1) =\int\limits^3_1 {3\tan^-(x^2-3x+2)} \, dx\\f(3) =3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx +f(1)\\f(3) =3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx +\dfrac{\pi}{2}[/tex]           .........1

Let the above equation is the equation number 1.

Let the integrated function,

[tex]y=3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx[/tex]

Solve the above equation using the trapezoidal rule.

Trapezoidal rule-

Trapezoidal rule is used to evaluate the area of the curve by using various strips of equal width which is in the form of trapezoids.

In the given problem,

[tex]h=\dfrac{b-a}{n}[/tex]

Use this formula for the integrated function,

[tex]h=\dfrac{3-1}{10}\\h=0.2[/tex]

Use the Simpson formula to solve the above equation,

[tex]=3\int\limits^3_1 {\tan^-(x^2-3x+2)} \, dx[/tex]

[tex]=\dfrac{h}{3} (y_0+y_{10})+4(y_1+y_3+y_{5}+y_7+y_{9})+2(y_2+y_{4}+y_6+y_{8})[/tex]

Find the value of y by putting the values in the given formula. Thus,

[tex]=\dfrac{0.2}{3} (0+3.3214)+4(-1.9039+2.8266+1.4133+6.1259+11.5657)+2(-1.4133-0.9519+1.4133+4.5899)\\=1.32804[/tex]

Put this value in equation 1,

[tex]f(3) =1.30824 +\dfrac{\pi}{2}\\f(3)=2.8989[/tex]

Thus the value of [tex]f(3)[/tex] is 2.8989.

Actually Welcome to the Concept of the Isosceles triangles.

Since, the sides are equal, we can equate them, so we get as,

==> 16x + 13 = 24x -19

=> 24x -16x = 13+19

=> 8x = 32

x = 4

hence ==> x = 4.

The function h(t)=-16t^+144 represents the height, h(t), in feet of an object from the ground at t seconds after it is dropped. A realistic domain for this function is?

Answers

Answer:

[tex]0 \le t \le 3[/tex]

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 144[/tex]

Required

Determine a reasonable domain

The domain is the possible values of t for which h(t) is true

Before the object is released, the value of t is:

[tex]t = 0[/tex]

Next, is to calculate the value of t after the ball reaches the ground.

At this point, h = 0.

So, we have:

[tex]h(t) = -16t^2 + 144[/tex]

[tex]0 = -16t^2 + 144[/tex]

[tex]16t^2 = 144[/tex]

Divide both sides by 16

[tex]t^2 = 9[/tex]

Take the positive square root of both sides

[tex]t = 3[/tex]

This means that the ball reaches the ground in 3 seconds.

So, the domain is:

[tex]0 \le t \le 3[/tex]

Step-by-step explanation:

2/3 x + 1/4 = 3

Subtract 1/4 from both sides.

2/3 x = 3 - 1/4

2/3 x = 12/4 - 1/4

2/3 x = 11/4

Multiply both sides by 3/2.

3/2 * 2/3 x = 3/2 * 11/4

x = 33/8
