Answer:
1/(ab) if a ≠ 0, b ≠ 0, and (a+b) ≠ 0
Step-by-step explanation:
You want the simplified form of 1/(a²+ab) +1/(ab+b²) and any applicable conditions.
SimplificationThe expression is simplified by writing it over a common denominator and cancelling any common terms from numerator and denominator.
[tex]\dfrac{1}{a^2+ab}+\dfrac{1}{ab+b^2}=\dfrac{1}{a^2+ab}\cdot\dfrac{b}{b}+\dfrac{1}{ab+b^2}\cdot\dfrac{a}{a}=\dfrac{b+a}{a^2b+ab^2}\\\\=\dfrac{a+b}{ab(a+b)}=\boxed{\dfrac{1}{ab}\quad a\ne0,b\ne0,(a+b)\ne0}[/tex]
The given conditions ensure the denominator(s) will not be zero.
12. "The sum of 9 and the product of a number and -7 is -19
Answer:
Step-by-step explanation:
We can use algebra to solve for the unknown number. Let's call the number "x".
The equation can be written as:
9 + x * (-7) = -19
Expanding the product on the left side:
9 + -7x = -19
Subtracting 9 from both sides:
-7x = -28
Dividing both sides by -7:
x = 4
So the number x is 4.

If x = logb2 and y = log b5, express log b100 in terms of x and y.
logb100=____?
Using logarithm expressing log b100 in terms of x and y is logb100 = 2y + x
What is the logarithm of a number?The logarithm of a number x to base a written as logₐy is such that when a is raised to the power of x,it equals y.
How to express logb100 in terms of x and y?Since
x = logb2 and y = log b5,We desire to express logb100 in terms of x and y.
So, we proceed as follows.
We have logb100, re-writing this, we have
logb100 = logb(25 × 2)
Now, applying the addition law of logarithm which states that
logab = loga + logb.
So, we have that
logb100 = logb(25 × 2)
logb100 = logb25 + logb2
= logb5² + logb2
Now applying the power rule of logarithm which states that logaⁿ = nloga
So,
logb100 = logb5² + logb2
= 2logb5 + logb2
= 2y + x
So, logb100 = 2y + x

The most appropriate viewing range for the quadratic function is given as follows:
Xmin 0, Xmax 10.YMin - 15, Ymax, 15.How to obtain the viewing range?The quadratic function for this problem is defined as follows:
f(x) = x² - 11x + 18.
The function can be factored as follows:
f(x) = (x - 2)(x - 9).
Hence the roots are:
x - 2 = 0 -> x = 2.x - 9 = 0 -> x = 9.Meaning that the viewing range should include x = 2 and x = 9.
The coefficients of the function are:
a = 1, b = -11, c = 18.
Hence the x-coordinate of the vertex is of:
x = -b/2a
x = 11/2
x = 5.5.
Hence the minimum value of the function is the y-coordinate of the vertex, given as follows:
y = 5.5² - 11(5.5) + 18
y = -12.25.
Meaning that Ymin should be less than -12.25.

1. Jack's gasoline-powered model airplane travels in a circle while the cord is held. How far does it travel in 5 full circles if the cord is 15 ft.?
2. Last Saturday Jack flew his airplane 100 times around a circle with a cord of 50 ft. If Jack increases the length of the cord by 10 ft and fly it for 100 circles, how much further will the plane travel?
1. The plane travelled a distance of 471.239 ft
2. The plane would travel further by 6283.185 ft
What is circumference?
The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area. The length of a straight line drawn from the centre of a circle equals the diameter of that circle.
If you move along a full circle of a radius 'r', the distance covered by you is equal to [tex]2\pi r[/tex]
Part 1:
Given that, Jack's aeroplane travels in a circle of a cord of length 15ft for 5 times
The total distance travelled by plane is [tex]15*2\pi *15[/tex]
[tex]=150\pi[/tex]
= 471.239 ft
Part 2:
Given that, Jack flew his aeroplane 100 times with a cord of 50 ft.
The total distance covered by the plane is 100 * (2*50*[tex]\pi[/tex])
If he increases the length by 10 ft, The cord will now be 60 ft.
The total distance it would cover then is 100 * (2*60*[tex]\pi[/tex])
Now,
100 * (2*60*[tex]\pi[/tex]) - 100 * (2*50*[tex]\pi[/tex])
= 100 * (2*(60-50))*[tex]\pi[/tex])
= 100 * 2 * 10 * [tex]\pi[/tex]

Mann Park is the shape of a triangle.
On a map, it has borders that measure 5 inches inches, 7 inches
and 9 inches. If the shortest border of Mann Park is
1000 meters long, how long in meters, is its longest
border?
The longest border of the Mann's park is 228.6 meter.
What is Triangle inequality theorem ?The Triangle Inequality It is a basic principle of geometry that the lengths of any two sides of a triangle must add up to more than the length of the third side. In other words, the longest side of any triangle must be shorter than the total length of the other two sides.
In this case, the shortest side of Mann Park measures 5 inches, and the two longer sides measure 7 inches and 9 inches.
So, the sum of the lengths of the two longer sides is:
' 7 inches + 9 inches = 16 inches.
Since 5 inches is less than 16 inches, we know that the 5-inch side is the shortest side, and the 9-inch side is the longest side.
One inch is approximately equal to 0.0254 meters, so we have:
= 9 inches x 0.0254 meters/inch
= 0.2286 meters
Since the shortest side is 1000 meters long, the longest side is:
= 1000 meters x 0.2286 meters/inch
= 228.6 meters long.
Therefore, the longest border of Mann Park is approximately 228.6 meters long.

Is the pair of events dependent or independent? Explain 14. You pick a number between 1000 and 5000. Then you flip a coin.
Answer:
Step-by-step explanation:
Here is a step-by-step explanation of the independence of the pair of events of choosing a number between 1000 and 5000 and flipping a coin:
Understanding the definition of independent events: Independent events are events that have no influence on each other. The outcome of one event does not affect the outcome of the other.
Event 1: Choose a number between 1000 and 5000: This event involves randomly selecting a number within the specified range.
Event 2: Flip a coin: This event involves flipping a coin and observing whether it lands on heads or tails.
Check for influence: To determine whether the events are independent, we need to check if the outcome of one event affects the outcome of the other. In this case, the outcome of the coin flip has no effect on the number you choose, and your choice of number has no effect on the outcome of the coin flip.
Conclusion: Since the outcome of one event does not affect the outcome of the other, the pair of events of choosing a number between 1000 and 5000 and flipping a coin are considered independent.
So, the pair of events of choosing a number between 1000 and 5000 and flipping a coin are independent events.

Explain how to find 20% of 160
Answer: 20% of 160 is 32.
Step-by-step explanation:
The percentage is from the word percent which means one part in a hundred. It is a part of the base or the whole determined by the rate. Usually, the percentage is smaller than the base. However, there are also cases where the percentage is greater than the base. This happens when the percent is greater than 100%.
To find the percentage, you have to multiply the base and the rate. The base is the 100% or original amount or the whole while the rate is the ratio of the percentage to the base and it has the percent sign (%). Remember that you have to convert the rate to a decimal number by moving the decimal point twice to the left.
Let us now find the 20% of 160.
20% = 0.2
percentage = 160 × 0.2

Solve for x, each figure is a trapezoid
From the given trapezoid the value of the x is 1.
What is the trapezoid?
The sum of all the angles in a trapezoid is equal to 360°. The sum of the angles on the same side is equal to 180°.
We have,
Since a Trapizode has 360 Degrees total and since the sides are equal we can say that
180 = 66 + ∠R
∠R = 180 - 66
∠R = 114
so,
180 = 66 + (-2 + 116x)
180 = 66 - 2 + 116x
180 = 64 + 116x
180 - 64 = 116x
