The degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.
What is the quotient?
The number we obtain when we divide one number by another is the quotient. For example, in 8 ÷ 4 = 2; here, the result of the division is 2, so it is the quotient. 8 is the dividend and 4 is the divisor.
To find the quotient and remainder when dividing 8x³ +16x² + 12x+13 by 2x+2, we can use polynomial long division.
First, we divide the leading coefficient of the dividend (8x³) by the leading coefficient of the divisor (2x). This gives us a quotient of 4x². We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the first term of the remainder:
8x³ +16x² + 12x + 13
(2x+2)(4x²)
8x³ - 8x³ -8x² -8x² +12x+13
This leaves us with 12x+13 as the first term of the remainder.
Next, we bring down the next term of the dividend (16x²) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 8x. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the next term of the remainder:
12x+13
(2x+2)(8x)
12x+13 - 16x² - 16x
-4x² -4x
This leaves us with -4x² -4x as the next term of the remainder.
Finally, we bring down the last term of the dividend (12x) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 6. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the final term of the remainder:
-4x² -4x
(2x+2)(6)
-4x² -4x -12x -12
-16x² -16x
This leaves us with -16x² -16x as the final term of the remainder.
Hence, the degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.
We can write the result of the division as:
(8x³ + 16x² + 12x + 13) ÷ (2x+2) = (4x² + 8x + 6) + (-16x² -16x)/(2x+2)

What are the types of triangle?
Basically, there are six different types of triangles in terms of lengths and measurements of triangle lines or angles. The sum of all interior angles of a triangle is always 180 degrees. This is called the angular summation of the triangle. Depending on the length of the sides, triangles can be divided into three types:
scale
Isosceles
equilateral
It is given that an isosceles triangle has an angle that measures 140°
We know that two sides of isosceles triangle are equal and by the property of triangle we know that angle opposite to equal sides are equal therefore remaning two angles of isosceles triangle will be equal.
Let the angles be x
By angle sum property of triangle
x + x + 140 = 180
2x = 180 - 140
2x = 40
x = 40/2 = 20
Therefore, the possible value of other two angles will be 20 degree.

It takes a bus 1 hour and 30 minutes to travel 42 miles.
Calculate the average speed of the bus in mph.
If your answer is a decimal, give it to 1 d.p.
28 mph is the average speed of the bus in mph.
What is speed?
The speed of a change in an object's location in any direction. The distance traveled relative to the time it took to travel that distance is how fast something is moving.
Meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph) are the most popular speed units (mph). The distance an object covers in a given amount of time is its speed. Speed = distance x time is the speed formula. The meter per second, also known as the m/s or ms-1, is the SI unit of velocity.
time = (1+ 1/2)hr = 3/2 hr = 1.5 hr
distance = 42 miles
average speed = total distance/total time
42/1.5 = 28 mph

The size of a population is modeled by the function P that satisfies the logistic differential equation dP/dt=(1/10)P - (1/5000)P^2 , where t is measured in months and P (0) = 50. What is the size of the population at the moment when the population is growing most rapidly? A. 50 B. 250 C.500 D. 2500
The correct answer is A.
500 is the size of the population at the moment of maximum growth.
Given data:
To find the size of the population at the moment when the population is growing most rapidly, we need to determine the maximum value of the derivative dP/dt.
Given the logistic differential equation [tex]\frac{dP}{dt} = (\frac{1}{10})P - (\frac{1}{5000})P^2[/tex], find the derivative by taking the derivative of each term separately:
[tex]\frac{dP}{dt} = (\frac{1}{10})P - (\frac{1}{5000})P^2[/tex]
To find the critical points where the derivative is zero or undefined, set dP/dt equal to zero:
[tex](\frac{1}{10})P - (\frac{1}{5000})P^2=0[/tex]
Simplifying:
[tex](\frac{1}{10})P= (\frac{1}{5000})P^2[/tex]
[tex]10P^2=5000P[/tex]
Dividing both sides by P and rearranging:
[tex]10P(P-500)=0[/tex]
This equation has two solutions: P = 0 and P = 500.
To determine which solution corresponds to the moment when the population is growing most rapidly, examine the second derivative. Taking the second derivative of the logistic differential equation, we have:
[tex]\frac{d^2P}{dt^2} = \frac{1}{10} - \frac{2}{5000}P[/tex]
Evaluating the second derivative at P = 0 and P = 500, we get:
[tex]\frac{d^2P}{dt^2}_{P=0} = \frac{1}{10} - \frac{2}{5000}(0)[/tex]
[tex]\frac{d^2P}{dt^2}_{P=0}= \frac{1}{10} > 0[/tex]
[tex]\frac{d^2P}{dt^2}_{P=500} = \frac{1}{10} - \frac{2}{5000}(500)[/tex]
[tex]\frac{d^2P}{dt^2}_{P=0}= -\frac{1}{10} < 0[/tex]
Since the second derivative is positive at P = 0 and negative at P = 500, the moment when the population is growing most rapidly occurs at P = 500.
Hence, the size of the population at the moment when the population is growing most rapidly is 500.

“According to Masterfoods, the company that manufactures M&M’s, 12% of peanut M&M’s are brown, 15% are yellow, 12% are red, 23% are blue, 23% are orange and 15% are green. [Round your answer to three decimal places, for example: 0.123]”
A probability is a numerical representation of the likelihood or chance that a specific event will take place.
How to find the probabilities?12% of peanut M&M’s = brown
15% = yellow
12% = red
23% = blue
23% = orange
15% = green
Here, Probability of an event is represented as P
a) P(not green) = 100% - 15%
= 85%
= 0.85
b) P(yellow or red) = 15% + 12%
= 27%
= 0.27
c) P(three blue) = 0.23*0.23 *0.23
= 0.012 (rounded to 3 decimal places)
d) P(not green if you choose 6 )= [tex](0.85)^{6}[/tex]
= 0. 377

A store bought a sofa wholesale for 200 and marked it up 15% when the sofa did int sell they reduced the price 15% show why the current price is not 200
Answer:
The current price of sofa is $195.50.
Step by Step explanation:Cost price of the sofa for the store = $200
Now, the store marked it up 15%.
So, marked price of sofa = $200 + 15% of $200
=200 + 30
=$230
Now, it is given that the sofa could not sell at this price. So, the store reduces its price by 15% now.
So, current price of sofa = $230 - 15% of $230
= 230 - 34.5
=$195.5
So, the current price of the sofa is $195.50.

Divergence and Curl In Mathematics, divergence is a differential operator, which is applied to the 3D vector-valued function. Similarly, the curl is a vector operator which defines the infinitesimal circulation of a vector field in the 3D Euclidean space .
So if we calculate for F:
F has a divergence potentially
divF = df/dx + dg/fy + dh/dz
But curl(F )= 0(all cross derivatives df/dy df/dz, dg/dx etc = 0)
For G
G has zero divergence.
divG = df/dx + dg/fy + dh/dz = 0 + 0 + 0 = 0
But it may have a curl.
curl(G) = df/dy may be non-zero
df/dz, dg/dx etc may all be non-zero
Now, we also know that if the divergence is zero, the vector field is incompressible and if the curl is zero, the vector field is irrotational, that is,
div = 0 = incompressible and
curl = 0= irrotational
Thus,
1. G is incompressible- True
2. F is irrotational- True
3. G is irrotational- False
4. F is incompressible- False
