Consider the angle shown below with an initial ray pointing in the 3-o'clock direction that measures θ radians (where 0≤θ<2π). The terminal point is (1.33,−2).
What is the angle's measure (in radians)?
θ=
Answer:
5.3 or (4217pi/2500)
Step-by-step explanation:
Create a right triangle with the coordinates provided.
We can ignore the negative sign and create the equation
[tex]tan(x) = \frac{1.33}{2} [/tex]
x = 33.624
We then add 270 and x together because the coordinates are in the 4th quadrant.
angle = 303.624
To convert to radians, we multiply this number by pi/180
5.3 radians
The measure of the angle is approximately [tex]1.687\pi[/tex] radians.
By trigonometry we can determine the direction of the terminal ray ([tex]\theta[/tex]), in radians, by the following inverse trigonometric function:
[tex]\theta = \tan^{-1}\frac{y}{x}[/tex] (1)
Since [tex]x > 0[/tex], [tex]y <0[/tex] and angle is in standard position, the angle must have a direction greater than [tex]\frac{3\pi}{2}[/tex] radians and less than [tex]2\pi[/tex] radians. Hence, we conclude that direction of the angle is:
[tex]\theta = \tan^{-1} \left(\frac{-2}{1.33} \right)[/tex]
[tex]\theta \approx 1.687\pi\, rad[/tex]
The measure of the angle is approximately [tex]1.687\pi[/tex] radians.

Quinn went to the coffee shop traveling 9mph and returned home traveling 15mph. The total trip took I hours. How long did Quinn travel at each speed?
Answer:
to the shop : 5/8 of an hour
back home : 3/8 of an hour
Step-by-step explanation:
We use the relationship between distance travelled, speed and time given by the formula:
speed = distance / time
We know that the distance from home to the coffee shop is D (same for trip back)
We also know the two speeds in one direction 9 mph and in the other 15 mph
then we can find the times t1 (to the coffee shop) and back (t2) by using the equations:
D = 9 * t1
D = 15 * t2
1 = t1 + t2
We set the two distances equal to have:
9 * t1 = 15 * t2
then t1 = 15 * t2 / 9 = 5 t2 / 3
and use this to substitute for t1 in the last equation:
t1 + t2 = 5 t2/3 + t2 = 1
8 t2 /3 = 1
then t2 = 3/8 of an hour
and therefore t1 must be 1 - t2 = 5/8 of an hour
Louis wants to carpet the rectangular floor of his basement. The basement has an area of 4,335 square feet. The width of the basement is
3/5 its length. What is the length of Louis's basement? The length is blank feet.
Answer:
The length of Louis's basement is 85 feet.
Step-by-step explanation:
The area of the basement, A = 4,335 square feet
The width of the basement is 3/5 its length.
Let length be l.
Width = (3/5)l
The area of the basement is given by :
[tex]A=l\times b\\\\4,335 =l\times \dfrac{3}{5}l\\\\4,335 =\dfrac{3}{5}l^2\\\\l^2=\dfrac{4,335 \times 5}{3}\\\\l=\sqrt{\dfrac{4335\times5}{3}}\\\\l=85\ ft[/tex]
So, the length of Louis's basement is 85 feet.

Mean:
Median:
Mode:
Answer:
1. Mean = 55.8
Median = 23
Mode = None
2. Mean = 2.1
Median = 1.4
Mode 0.5
3. Mean = 4.5
Median = 4.5
Mode = 1,4, 5, 8
4. Mean 68
Median 58
Mode = 0
Step-by-step explanation:
Mean = 17 + 25 + 23 + 200 + 14 / 5 = 279/5 = 55.8
Median= Because its odd you put them in order 17, 14, 23, 25, 200 = 23 because it is the middle number. Mode = None
2. Mean = 0.5 + 1.4 + 3.0 + 7.0 + 0.5 +1.8 + 0.5 = 14.7 = 14.7/7 = 2.1
Median = because it is odd you put them in order 0.5, 0.5, 0.5, 1.4, 1.8, 3.0, 7.0 = 1.4 The mode is 0.5 because it repeats three times
3. Mean = 1 + 8 + 5 + 4 + 1 + 8 + 5 + 4 = 36/8 =4.5
Median = Because its even you divide by the two middle numbers = 1, 1, 4,4, 5, 5 , 8 , 8 = 4+5 = 9/2 = 4.5 Mode = 1, 4, 5, and 8 are the numbers that are repeated most often.
Mean = 0+78+99+58+65+0+47+38+227 = 68 Median, Because there is an odd number you get the odd number from the middle. 0, 0, 38, 47, 58, 65, 78, 99, 227 = 58 Mode = 0 because it repeats more often.

The temperature was -13 °F and then fell 5 degrees.
What was the final temperature?
Answer:
-8
Step-by-step explanation:
The final temperature was -18 °F if it decreased by 5 degrees.
What is the addition operation?The addition operation in mathematics adds values on each side of the operator.
For example 4 + 2 = 6
The temperature was -13 °F and then dropped 5 degrees.
As per the question, we have data as follows:
The initial temperature = -13 °F
The changed temperature = -5 °F (negative sign indicates temp dropped)
Final temperature = initial temperature + changed temperature
Final temperature = -13 °F + (-5 °F)
Final temperature = -13 °F - 5 °F
Apply the addition operation, and we get
Final temperature = -18 °F
Therefore, the final temperature was -18 °F.

A store has 4 cases of juice boxes and has a total of 144 juice boxes. The manager wants to know the numbers of juice boxes for different numbers for different numbers of cases. Enter the correct answers in the boxes.
Answer:
first you have to divide the 144 by 4 to get the answer which is 36
Step-by-step explanation:
144÷4=36
then you take 3 × 36= 108 juice boxes
then you take the number of juice boxes which is 36 and divide it by 36 which is 1 case
the you take 6×36=216
288÷36 = 8 cases

Step-by-step explanation:
88 ÷ 8 = 11
and 11 - 12 = -1
Answer:
88
Step-by-step explanation:
We can turn this into an algebraic equation. So...
x/8-12=-1 Add 12 to both sides.
+12 +12
x/8=11 Multiply by 8 on both sides.
*8 *8
x=88

use the approximate operation count 2n^3 /3 for guassian elimination to estimate how much longer it takes to solve n equations in n unknowns if n is tripled
Answer:
the appropriate operation count is 27 times longer than the original one.
Step-by-step explanation:
Given the data in the question;
let us consider the approximate operation count for the system of n₁ equation in n₁ unknowns as; [tex]\frac{2}{3}n[/tex]₁³ Or
O₁ = [tex]\frac{2}{3}n[/tex]₁³
so if the value of the unknowns is tripled i.e, n₂ = 3n₁,
the appropriate operation count will be;
O₂ = [tex]\frac{2}{3}n[/tex]₂³
= [tex]\frac{2}{3}(3n_{1})[/tex]³
= [tex]\frac{2}{3}[/tex] × 27 × n₁³
= 27( [tex]\frac{2}{3}n[/tex]₁³ )
O₂ = 27(O₁)
Therefore, the appropriate operation count is 27 times longer than the original one.
