Answer:
3π/4
Step-by-step explanation:
A multiple of 2π can be added or subtracted from the given angle to make a coterminal angle. Here, we need to subtract 4π = 16π/4 to get the angle in the desired range.
19π/4 -16π/4 = 3π/4 . . . . angle coterminal with the given angle

The length of a rectangle is three times its width the length is 3 3/4 feet. What is the area if the rectangle?
Answer:
A = 4 11/16 or 4.6875
Step-by-step explanation:
3 3/4 = 3W
divide both sides by 3
15/4 divided by 3 = W
15/4 x 1/3 = W
5/4 = W
A = L x W
3 3/4 x 1 1/4 = 15/4 x 5/4 = 75/16 = 4 11/16

A sculpture of the Earth is 829 kg. How many hydrpgen atoms
The number of hydrogen atoms present in the sculpture of earth if the mass of earth is 829 kg is 4.145 × 10²⁹.
Given that,
Mass of the sculpture of the earth = 829 kg
We know that,
Mass of an hydrogen atom = 2 × 10⁻²⁷ kg
Number of hydrogen atoms = Mass of earth / Mass of hydrogen atom
= 829 / 2 × 10⁻²⁷
= 414.5 × 10²⁷
= 4.145 × 10²⁹
Hence the required number of atoms is 4.145 × 10²⁹.

Find the exterior of a rectangle in a polygon
The measure of each exterior angles of rectangle is 90°
Finding the exterior of a rectangle in a polygonFrom the question, we have the following parameters that can be used in our computation:
A rectangle
A rectangle is a polygon with 4 sides
So, the measure of the exterior angle can be calculated using the formula for the exterior angles in a polygon
The exterior angles in a polygon are found by using:
Exterior of a rectangle in a polygon = 360°/Number of sides of the polygon
In this case,
The number of sides of the rectangle = 4
So, we have
Exterior of a rectangle = 360°/4
Evaluate
Exterior of a rectangle = 90°
Hence, the value of the measure of each exterior angles of rectangle is 90°

Answer:
7.5 -ln(0.25)
Step-by-step explanation:
We can first graph this function. Looking at the graph, we can separate this into two ranges -- from x=0.25 to x=1 and from x=1 to x=4.
From x=0.25 to x=1, we want to find the area above y=1/x and below y=4. To do this, we can take the integral of y=4 from x=0.25 to x=1 to encompass the whole area under y=4 from that range. Then, we subtract the area under y=1/x as we don't need that (we only want what's above it). Therefore, we have
\(\int\limits^{1}_{0.25}{4} \, dx - \int\limits^{1}_{0.25} {1/x} \, dx \\= 4(1) - 4 (0.25) - (ln(1) - ln(0.25))\\= 4 - 1 - ln(1) + ln(0.25)\\= 3 - ln(1) + ln(0.25)\)
Next, we know that ln(x/y) = ln(x) - ln(y), so ln(0.25) - ln(1) = ln(0.25/1) = ln(0.25), so we have
3 - ln(0.25)
For x=1 to x=4, we want to find the area above y=x and below y=4. We can apply a similar strategy, subtracting the area below y=x from the area below y=4 to get
\(\int\limits^{4}_{1}{4} \, dx - \int\limits^{4}_{1} {x} \, dx \\ \\= 4(4) - 4(1) - (4^{2} /2 - 1^2/2)\\= 16 - 4 - 8 + 0.5\\= 4.5\)
Add these two areas up to get
3-ln(0.25) + 4.5 = 7.5 -ln(0.25)

If you wrote down a 5, what is the probability the card you drew was a diamond
Answer:
Probability of diamond card selected when 5 is write down = \(\frac{2}{11}\)
Step-by-step explanation:
Given - You decide to perform an experiment with a standard deck of 52 cards and a set of 6-sided dice. You start by randomly picking a card from the deck. If the card is a diamond, you roll 2 dice and record the sum of the dice. Otherwise, you roll 1 die and record the value of the die.
To find - If you wrote down a 5, what is the probability the card you drew was a diamond ?
Proof -
Total Number of cards in a deck = 52
Total number of Diamond card in a deck = 13
Now,
P(diamond card) = \(\frac{13}{52}\) = \(\frac{1}{4}\)
P(not a diamond card) = 1 - \(\frac{1}{4}\) = \(\frac{3}{4}\)
Now,
Total outcomes when two dice are rolled = 36
Total outcome of getting 5 when two dice are rolled = { (1,4), (2,3). (3,2), (4,1) }
So,
P(Sum 5 when two dice are rolled ) = \(\frac{4}{36}\) = \(\frac{1}{9}\)
P(Sum 5 when one dice is rolled ) = \(\frac{1}{6}\)
Now,
P(sum 5 when diamond card is selected) = \(\frac{1}{4}\) × \(\frac{1}{9}\) = \(\frac{1}{36}\)
P(sum 5 when diamond card is not selected = \(\frac{3}{4}\) × \(\frac{1}{6}\) = \(\frac{1}{8}\)
Now,
Probability (Getting 5) = \(\frac{1}{36}\) + \(\frac{1}{8}\) = \(\frac{11}{72}\)
Now,
Probability of diamond card selected when 5 is write down = \(\frac{\frac{1}{36} }{\frac{11}{72} }\)
= \(\frac{1}{36}\) ×\(\frac{72}{11}\) = \(\frac{2}{11}\)
⇒Probability of diamond card selected when 5 is write down = \(\frac{2}{11}\)

In the following diagram, ABCDABCD is a square. The coordinates of the vertices A,B,CA,B,C and DD are (3,3),(8,3),(8,8)(3,3),(8,3),(8,8) and (3,8)(3,8) respectively.
The square is dilated from the origin by a factor of 1111 to give A′B′C′D′A′B′C′D′.
What are the coordinates of point C′C′? (NEED THIS ASAP)
Answer:
Step-by-step explanation:
To dilate the square by a factor of 1111 from the origin, we need to multiply each coordinate by 1111.
The coordinates of point C are (8,8). So, to find the coordinates of point C' after dilation, we can simply multiply each coordinate by 1111:
x-coordinate of C' = 1111 * 8 = 8888
y-coordinate of C' = 1111 * 8 = 8888
Therefore, the coordinates of point C' are (8888, 8888).

let d be diagonal, with repeated diagonal entries grouped contiguously. show that if a commutes with d, then it must be block diagonal.
As, a is block diagonal, with diagonal blocks of size \(m_1 \times m_1\), \(m_2 \times m_2\), \(\dots\), \(m_k \times m_k\), respectively. So, if a commutes with d, then it must be block diagonal.
Let's suppose that d is a diagonal matrix with repeated diagonal entries grouped contiguously, i.e.,
d = \(\begin{pmatrix} D_1 & 0 & 0 & \cdots & 0 \ 0 & D_1 & 0 & \cdots & 0 \ 0 & 0 & D_2 & \cdots & 0 \ \vdots & \vdots & \vdots & \ddots & \vdots \ 0 & 0 & 0 & \cdots & D_k \end{pmatrix}\),
where \(D_1, D_2, \dots, D_k\) are scalars and appear with frequencies \(m_1, m_2, \dots, m_k\), respectively, so that \(m_1 + m_2 + \dots + m_k = n\), the size of the matrix.
Suppose that \(a\) is a matrix that commutes with d, i.e., ad = da.
Then, for any \(i \in {1, 2, \dots, k}\), we have
\(ad_{ii} = da_{ii}\)
Here, \(d_{ii}\) denotes the \(i$th\) diagonal entry of d, i.e., \(d_{ii} = D_i\) for \(i = 1, 2, \dots, k\). Since d is diagonal, \(d_{ij} = 0\) for \(i \neq j\), and
hence
\(ad_{ij} = da_{ij} = 0\)
for all \(i \neq j\).
Therefore, a is also diagonal, with diagonal entries \(a_{ii}\), and we have
\(a = \begin{pmatrix} a_{11} & 0 & 0 & \cdots & 0 \ 0 & a_{11} & 0 & \cdots & 0 \ 0 & 0 & a_{22} & \cdots & 0 \ \vdots & \vdots & \vdots & \ddots & \vdots \ 0 & 0 & 0 & \cdots & a_{kk} \end{pmatrix}\)
Thus, a is block diagonal, with diagonal blocks of size \(m_1 \times m_1\), \(m_2 \times m_2\), \(\dots\), \(m_k \times m_k\), respectively.
Therefore, if a commutes with d, then it must be block diagonal.

The mean life of a new smart LED bulb is 20,000 running hours with a standard deviation is 2,250 hours. The data is normally distributed. If a home improvement store sold 18,000 of these light bulbs in the first year of production, how many light bulbs would you expect to last longer than 22,250 hours?
Answer: The expected number of bulbs that would last longer than 22,250 hours is approximately 2,857.
Step-by-step explanation:
To solve this problem, we can start by finding the z-score for 22,250 using the formula:z = (x - mean) / standard deviationz = (22,250 - 20,000) / 2,250 = 1Next, we need to find the proportion of bulbs lasting longer than 22,250. We can look up this proportion in a standard normal distribution table or use a calculator, which gives us a probability of 0.1587.Finally, we can use this probability to find the expected number of bulbs that will last longer than 22,250:Expected number of bulbs = probability * total number of bulbs sold Expected number of bulbs = 0.1587 * 18,000 = 2,857Therefore, we can expect that approximately 2,857 of the 18,000 bulbs sold will last longer than 22,250 running hours.
