How many 45 angles would it take to turn in a complete circle???
Answer:
8
Step-by-step explanation:
A complete circle is 360 degrees so we divide 360/45 and that is equal to 8
y’ =2x - 3y + 1,y(1) = 5; y(1.2)
Applying Euler's method:
Let f(x, y) = 2x - 3y + 1, and consider the following recurrence relations:
[tex]\begin{cases}x_0=1\\x_n=x_{n-1}+h&\text{for }n\ge1\end{cases}[/tex]
[tex]\begin{cases}y_0=5\\y_n=y_{n-1}+f(x_n,y_n)h&\text{for }n\ge1\end{cases}[/tex]
For step size h = 0.1, we can approximate y (1.2) with just 2 steps:
[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.1=3.8[/tex]
[tex]\begin{cases}x_1=1+0.1=1.1\\y_1=3.8\end{cases}\implies y_2=3.8+f(1.1,3.8)\times0.1=\boxed{2.98}[/tex]
For step size h = 0.05, we need 4 steps:
[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.05=4.4[/tex]
[tex]\begin{cases}x_1=1+0.05=1.05\\y_1=4.4\end{cases}\implies y_2=4.4+f(1.05,4.4)\times0.05=3.895[/tex]
[tex]\begin{cases}x_2=1.05+0.05=1.1\\y_2=3.895\end{cases}\implies y_3=3.895+f(1.1,3.895)\times0.05=3.47075[/tex]
[tex]\begin{cases}x_3=1.1+0.05=1.15\\y_3=3.47075\end{cases}\implies y_4=3.47075+f(1.15,3.47075)\times0.05\approx\boxed{3.1151375}[/tex]
(Compare these to the value of y (1.2) found using the exact solution to the differential equation, about 3.22832.)

What is the measure of the angle of the hands on a clock if it is 3:24?
Answer:
from 3 o’clock until 3:20, the minute hand will move 1/3 of the way around the circle or 120 degrees. But the hour hand has also moved 1/3 of the way to the next number, or 10 degrees.
Answer:
42deg
Step-by-step explanation:
Let's see.
We'll consider 12:00 the "starting position"
The minute hand moves with the speed of 360deg in an hour, so 6deg per minute.
The hour hand moves with the speed of 360deg in 12hours, so 30deg per hour, so 0.5deg per minute.
at 3:24, the minute hand has moved 24*6deg=144deg from the starting position, while the hour hand has moved by 3*30deg + 24*0.5deg = 102deg
The absolute difference of the angles is 144deg-102deg = 42deg and it's the angle between the hands.

35. Para pintar una casa se mezclaron 5/4 L do pintura blanca y 1/2 L de pintura azul. Al final solo se emplearon 213 L de la mezda,
¿cuántos litros de pintura sobraron?
Answer:
Total paint left over = [tex]\frac{13}{12}L[/tex]
Step-by-step explanation:
Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint
were mixed. In the end only 2/3 L of the mixture were used.
To find - How many liters of paint were left over ?
Proof -
Given that,
5/4 L of white paint and 1/2 L of blue paint were mixed.
So, total mixture = [tex](\frac{5}{4} + \frac{1}{2})L[/tex]
= [tex]\frac{5 + 2}{4}L[/tex]
= [tex]\frac{7}{4}L[/tex]
⇒Total mixture = [tex]\frac{7}{4}L[/tex]
Now,
Given that ,
In the end only 2/3 L of the mixture were used.
So, total mixture left = [tex](\frac{7}{4} - \frac{2}{3})L[/tex]
= [tex]\frac{21 - 8}{12}L[/tex]
= [tex]\frac{13}{12}L[/tex]
∴ we get
Total paint left over = [tex]\frac{13}{12}L[/tex]
