If arc cos = -8/17 and arc sin is negative, then arcsin is _____ and arctan is ______
Answers
To find arcsin, we need to use the identity:
sin(arcsin(x)) = x
Since arcsin is negative, sin(arcsin) is also negative. Therefore, we can say:
sin(arcsin) = -sqrt(1 - (cos)^2)
where (cos)^2 = 8/17
Substituting, we get:
sin(arcsin) = -sqrt(1 - (8/17))
Simplifying, we get:
sin(arcsin) = -sqrt(17/17 - 8/17)
Simplifying further, we get:
sin(arcsin) = -sqrt(9/17)
Therefore, arcsin = -sqrt(9/17)
To find arctan, we need to use the identity:
tan(arctan(x)) = x
Substituting, we get:
tan(arctan) = -8/17
Therefore, arctan = -8/17
So, arcsin is -sqrt(9/17) and arctan is -8/17.

q = c4(h + r) for r
Select one:
a. r = 4cq - h
b. r = q4c - h
c. r = 4q−hc
d. r = 4qc - h
Answers
Answer:
Option (c) "\(r=\dfrac{q}{4c}-h\)"
Step-by-step explanation:
The given equation is :
q = c4(h + r)
We need to solve it for r.
Dividing both sides of the given equation by 4c.
\(\dfrac{q}{4c}=\dfrac{4c}{4c}(h+r)\\\\(h+r)=\dfrac{q}{4c}\)
Now, subtract h both sides of the equation.
\(h+r-h=\dfrac{q}{4c}-h\\\\r=\dfrac{q}{4c}-h\)
Hence, this is the required solution.

Answers
-1.5 or -1 and a half
On a number line M is located at -7 and N is located at four then the midpoint of segment MN is -3/2.
What does a midpoint mean?Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.
SO, Midpoint of the two values is half the absolute value of their difference added to the lowest value.
Find the Midpoint
O = 1/2 |M - N| + M
O = 1/2 |-7 - 4 | + (-7)
The absolute value turns any number into the positive form;
O = 1/2 |- 11 | + (-7)
O = 11/2 + (-7)
O = -3/2
The midpoint is -3/2.
Therefore, On a number line M is located at -7 and N is located at four then the midpoint of segment MN is -3/2.

The equation r(t) = sin(4t)i + cos(4t)j, 0t≥0 describes the motion of a particle moving along the unit circle. Answer the following questions about the behavior of the particle.
a. Does the particle have constant speed? If so, what is its constant speed?
b. Is the particle's acceleration vector always orthogonal to its velocity vector?
c. Does the particle move clockwise or counterclockwise around the circle?
d. Does the particle begin at the point (1,0)?
Answers
Answer:
a) Particle has a constant speed of 4, b) Velocity and acceleration vector are orthogonal to each other, c) Clockwise, d) False, the particle begin at the point (0,1).
Step-by-step explanation:
a) Let is find first the velocity vector by differentiation:
\(\vec v = \frac{dr_{x}}{dt} i + \frac {dr_{y}}{dt} j\)
\(\vec v = 4\cdot \cos 4t\, i - 4 \cdot \sin 4t \,j\)
\(\vec v = 4 \cdot (\cos 4t \, i - \sin 4t\,j)\)
Where the resultant vector is the product of a unit vector and magnitude of the velocity vector (speed). Velocity vector has a constant speed only if magnitude of unit vector is constant in time. That is:
\(\|\vec u \| = 1\)
Then,
\(\| \vec u \| = \sqrt{\cos^{2} 4t + \sin^{2}4t }\)
\(\| \vec u \| = \sqrt{1}\)
\(\|\vec u \| = 1\)
Hence, the particle has a constant speed of 4.
b) The acceleration vector is obtained by deriving the velocity vector.
\(\vec a = \frac{dv_{x}}{dt} i + \frac {dv_{y}}{dt} j\)
\(\vec a = 16\cdot (-\sin 4t \,i -\cos 4t \,j)\)
Velocity and acceleration are orthogonal to each other only if \(\vec v \bullet \vec a = 0\). Then,
\(\vec v \bullet \vec a = 64 \cdot (\cos 4t)\cdot (-\sin 4t) + 64 \cdot (-\sin 4t) \cdot (-\cos 4t)\)
\(\vec v \bullet \vec a = -64\cdot \sin 4t\cdot \cos 4t + 64 \cdot \sin 4t \cdot \cos 4t\)
\(\vec v \bullet \vec a = 0\)
Which demonstrates the orthogonality between velocity and acceleration vectors.
c) The particle is rotating clockwise as right-hand rule is applied to model vectors in 2 and 3 dimensions, which are associated with positive angles for position vector. That is: \(t \geq 0\)
And cosine decrease and sine increase inasmuch as t becomes bigger.
d) Let evaluate the vector in \(t = 0\).
\(r(0) = \sin (4\cdot 0) \,i + \cos (4\cdot 0)\,j\)
\(r(0) = 0\,i + 1 \,j\)
False, the particle begin at the point (0,1).
y’ =2x - 3y + 1,y(1) = 5; y(1.2)
Answers
Applying Euler's method:
Let f(x, y) = 2x - 3y + 1, and consider the following recurrence relations:
\(\begin{cases}x_0=1\\x_n=x_{n-1}+h&\text{for }n\ge1\end{cases}\)
\(\begin{cases}y_0=5\\y_n=y_{n-1}+f(x_n,y_n)h&\text{for }n\ge1\end{cases}\)
For step size h = 0.1, we can approximate y (1.2) with just 2 steps:
\(\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.1=3.8\)
\(\begin{cases}x_1=1+0.1=1.1\\y_1=3.8\end{cases}\implies y_2=3.8+f(1.1,3.8)\times0.1=\boxed{2.98}\)
For step size h = 0.05, we need 4 steps:
\(\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.05=4.4\)
\(\begin{cases}x_1=1+0.05=1.05\\y_1=4.4\end{cases}\implies y_2=4.4+f(1.05,4.4)\times0.05=3.895\)
\(\begin{cases}x_2=1.05+0.05=1.1\\y_2=3.895\end{cases}\implies y_3=3.895+f(1.1,3.895)\times0.05=3.47075\)
\(\begin{cases}x_3=1.1+0.05=1.15\\y_3=3.47075\end{cases}\implies y_4=3.47075+f(1.15,3.47075)\times0.05\approx\boxed{3.1151375}\)
(Compare these to the value of y (1.2) found using the exact solution to the differential equation, about 3.22832.)
For the following vectors, (a) find the dot product v•w ; (b) find the angle between v and w , (c) state whether the vectors are parallel, octagonal, or neither. V=-3i-4j, w=6i+8j
A- v•w
B-the angle between v and w is theta ^•?
C- the vectors v and w are?
Answers
B) The angle between vectors v and w can be found using the formula: cos(theta) = (v • w) / (||v|| ||w||), where ||v|| and ||w|| are the magnitudes of vectors v and w respectively.
First, we need to find ||v|| and ||w||:
||v|| = sqrt((-3)^2 + (-4)^2) = 5
||w|| = sqrt((6)^2 + (8)^2) = 10
Now, we can substitute in the values to get:
cos(theta) = (-50) / (5 * 10) = -1
theta = arccos(-1) = pi radians or 180 degrees.
Therefore, the angle between vectors v and w is 180 degrees.
C) Two vectors are parallel if their directions are the same, which can be determined by comparing their unit vectors.
The unit vector of v is:
v_hat = v / ||v|| = (-3/5)i + (-4/5)j
The unit vector of w is:
w_hat = w / ||w|| = (6/10)i + (8/10)j = (3/5)i + (4/5)j
We can see that the unit vectors are in opposite directions, which means that the vectors are anti-parallel or opposite. Therefore, the vectors v and w are neither parallel nor orthogonal.

if the letter l,o,g,ic are randomnly arranged to form word logic what is the probability that result will be woord logic
Answers
The probability of randomly forming the word "woord logic" is:Probability = 1 / (10! / (2!))
To calculate the probability of forming the word "woord logic" by randomly arranging the letters l, o, g, i, c, we need to consider the total number of possible arrangements and the number of arrangements that result in the desired word.
The word "woord logic" has 10 letters in total. Among these letters, there are 2 o's and the remaining letters appear only once.
The total number of possible arrangements is given by the factorial of the total number of letters:
Total arrangements = 10!
However, since the letter "o" appears twice, we need to divide by the factorial of the number of repeated letters:
Total arrangements = 10! / (2!)
To calculate the number of arrangements that result in "woord logic," we consider that the arrangement of "woord logic" is unique and distinct. Thus, there is only one arrangement that matches the desired word.Simplifying this expression would yield the exact probability.

What are the statistical tools for describing temperatures?We can describe temperatures using measures of central tendencies (especially the mean, median, and mode).
The mean temperature is the average, which shows the overall trend in temperature changes. It is computed by adding up the temperatures for the period and diving by the number of data values.
In addition, the median gives the middle value when the data set is ordered in ascending or descending orders. Similarly, the mode gives the highest temperature occurrence within the period. It may not be useful here.
We can estimate the difference between the highest and lowest temperature for the week with the range.
A line graph (showing connecting lines) and a stem-and-leaf plot (like a bar graph) can graphically describe the temperatures for the week.

Answer the questions below to find the total surface area of the can.
Answers
Answer:
\(\begin{aligned}SA &= 7.125\pi \text{ in}^2\\& \approx 22.4 \text{ in}^2 \end{aligned}\)
Step-by-step explanation:
We can find the Surface Area of the can by adding the areas of each of its parts:
\(SA = 2( A_{\text{base}}) + A_\text{side}\)
First, we can calculate the area of the circular base:
\(A_{\text{circle}} = \pi r^2\)
\(A_{\text{base}} = \pi (0.75 \text{ in})^2\)
\(A_{\text{base}} = 0.5625\pi \text{ in}^2\)
Next, we can calculate the area of the rectangular side:
\(A_\text{rect} = l \cdot w\)
\(A_\text{side} = (4\text{ in}) \cdot C_\text{base}\)
Since the width of the side is the circumference of the base, we need to calculate that first.
\(C_\text{circle} = 2 \pi r\)
\(C_\text{base} = 2 \pi (0.75 \text{ in})\)
\(C_\text{base} = 1.5 \pi \text{ in}\)
Now, we can plug that back into the equation for the area of the side:
\(A_\text{side} = (4\text{ in}) (1.5\pi \text{ in})\)
\(A_\text{side} = 6\pi \text{ in}^2\)
Finally, we can solve for the surface area of the can by adding the area of each of its parts.
\(SA = 2( A_{\text{base}}) + A_\text{side}\)
\(SA = 2(0.5625\pi \text{ in}^2) + 6\pi \text{ in}^2\)
\(\boxed{SA = 7.125\pi \text{ in}^2}\)
\(\boxed{SA \approx 22.4 \text{ in}^2}\)
