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°

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

Answers
Answer:
[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]
Step-by-step explanation:
Given
[tex]\frac{4}{3 - i}[/tex]
See attachment for question
Required
Correct Ramon's error
Start by rationalizing the expression:
[tex]\frac{4}{3 - i} = \frac{4}{3 - i}*\frac{3 + i}{3 + i}[/tex]
[tex]\frac{4}{3 - i} = \frac{4(3 + i)}{(3 - i)(3 + i)}[/tex]
Expand
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{3^2 - i^2}[/tex]
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - i^2}[/tex]
In complex numbers:
[tex]i^2 = -1[/tex]
So:
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - (-1)}[/tex]
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 +1}[/tex]
[tex]\frac{4}{3 - i} = \frac{12 + 4i}{10}[/tex]
Split fraction
[tex]\frac{4}{3 - i} = \frac{12}{10} + \frac{4i}{10}[/tex]
[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]

A container has 20 12 cups of pancake mix. A serving uses exactly 2 ) cups.
Part A
How many full servings are in the container?
full servings
(a)
Part B
How many cups of pancake mix are left over?
Answers
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.
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:

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]

By simpson's 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. 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.

You observe that the values are given in the figure for an acute angle in a right triangle, the hypotenuse, and the side opposite the angle. That is why you are interested in the sine relation.
sin(49°) = x/33
x = 33·sin(49°) ≈ 24.905
