Answer:

[tex]x^{2} +y^{2} =9[/tex]

Step-by-step explanation:

Answer:

En este caso 70 ° y 20 ° son complementarios porque 70° + 20° = 90°.

Más ejemplos podrían ser 47° y 43°, ya que 47° + 43° = 90°, 30° y 60°, 45° y 45° , etc.

Dos ángulos son suplementarios si su suma forma un ángulo llano, es decir, 180°.

Answer:

Step-by-step explanation:

To find the slope you need to follow the formula shown below.

Slope (m) = ΔY/ΔX

Now solve

ΔY = 6 – 0 = 6

ΔX = 2 – 0 = 2

Write as a fraction

6/2

Convert to a number

6/2 = 3

And you have your slope. Now you just have to plot the points on the graph. As I said before, you can use any two points from the table.

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]

Answer:

1. I don't know how to solve that sorry :(

2. B. It is a diameter

3. 30° = q

4. I don't know sorry :(

Step-by-step explanation:

1. I don't know how to solve that sorry :(

-----------------------------------------------------------

2. B. It is a diameter

------------------------------------

3. All triangles = 180°

180° = 60° + 90° + q

180° = 150° + q

180° - 150° = 150° - 150° + q

30° = q

180° = 60° + 90° + 30°

180° = 150° + 30°

180° = 180°

------------------------------------------

4. I don't know sorry :(

Answer:

For this question, we need to use a little bit of trigonometry.

We have: sine 17 = x/47

Simplifying: 0.29 = x/47

Multiply both sides by 47 to get: x is about  13.7

Let me know if this helps!

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

y   f(0)  f(1.2)   f(1.4)   f(1.6)   f(1.8)   f(2.0)  f(2.2)  f(2.4)  f(2.6)  f(2.8)   f(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]=\dfrac{0.2}{3}\Big[(0+3.3214)+(-1.9039+2.8265+1.4133+6.1259+11.5657)+2(-1.4133-0.9519+1.4133+4.5899)\Big][/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 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.

Answer:

10 full servings and [tex]\frac{1}{4}[/tex] cups leftover

Step-by-step explanation:

Our container has a total of 20 and a half cups. And each full serving is 2 cups.

So, we divide [tex]\frac{20\frac{1}{2} }{2}[/tex].

To do this manually, we convert the numerator into an improper fraction: [tex]\frac{\frac{41}{2} }{2}[/tex].

Now, we multiply the denominators: [tex]\frac{41}{4}[/tex].

This will give us [tex]10\frac{1}{4}[/tex] servings. So we only have 10 full servings.

There are [tex]\frac{1}{4}[/tex] cups leftover.
