The width of a rectangle is 8 units less than the length. The area of the rectangle is 9 square units. What is the length, in units, of the rectangle?
Answers
The length, in units, of the rectangle is 9 units.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Length = x
Width = x - 8
Area = 9 square units
Now,
The area of the rectangle = length x width
9 = x (x - 8)
9 = x² - 8x
x² - 8x - 9 = 0
Solve for x.
x² - 8x - 9 = 0
x² - (9 - 1)x - 9 = 0
x² - 9x + x - 9 = 0
x(x - 9) + 1(x - 9) = 0
(x - 9) (x + 1) = 0
x - 9 =0 and x + 1 = 0
x = 9 and x = -1 (rejected)
Now,
Length = 9
Width = 9 - 8 = 1

Answers
Option(a) is the correct answer.
The inequality is:
|X+6|- 12 < 13
Here we can add 12 to both sides:
|X+6| <13 + 12
⇒|X+6| <25
⇒|X+6| < 25
We can separate it into two equations:
if x > -6, then |X+6| = x + 6
⇒ (x + 6) < 25
⇒x < 25 - 6
⇒ x < 19
if x < -6, then |X+6| = -(x + 6)
⇒-(x + 6) < 25
⇒ -x < 31
⇒ x > -31 (changing the sign)
And with those two equations, we get the:

A rectangular garden has a walkway around it. The area of the garden is 6(2.5x+1.5). The combined area of the garden and the walkway is 7.5(4x+5). Find the area of the walkway around the garden as the sum of two terms.
Answers
The area of the walkway around the garden as the sum of two terms is, 2(w + l) = 2(8x + 21).
What is the area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Let's call the width of the garden w and the length of the garden l.
Then, the area of the garden is,
wl = 6(2.5x + 1.5).
The combined area of the garden and the walkway is 7.5(4x + 5).
We can write this as wl + 2(w + l), since the walkway goes around the perimeter of the garden.
Equating the two expressions for the combined area, we have:
wl + 2(w + l) = 7.5(4x + 5)
Substituting wl = 6(2.5x + 1.5), we get:
6(2.5x + 1.5) + 2(w + l) = 7.5(4x + 5)
Expanding both sides, we get:
15x + 9 + 2w + 2l = 30x + 37.5
Solving for w + l, we get:
w + l = 15x + 28.5 - 7.5 = 8x + 21
So the area of the walkway around the garden can be expressed as 2(w + l) = 2(8x + 21).

Answers
x is not an integer, and is instead an irrational number that lies between -1/6 and 1/9.
We can solve this problem using the law of sines. The law of sines states that for a triangle, the ratio of the side opposite an angle to the sine of that angle is equal for all three angles. Therefore, we can solve for x by setting up two equations, one for angle W and one for angle X.
For angle W, the equation is:
18x - 2 = sin-1(VX/WY)
For angle X, the equation is:
12x + 2 = sin-1(VW/YX)
Since we know the ratio of the sides of the triangle, we can solve for x by substituting these values into the equations.
For angle W, we get:
18x - 2 = sin-1(VX/WY)
18x - 2 = sin-1(2/2)
18x - 2 = 0
18x = 2
x = 1/9
For angle X, we get:
12x + 2 = sin-1(VW/YX)
12x + 2 = sin-1(2/2)
12x + 2 = 0
12x = -2
x = -1/6
Since these two answers do not match, we can conclude that x is not an integer, and is instead an irrational number that lies between -1/6 and 1/9.

Answers
The entropy of X (number of defective chips) in bits is a measure of uncertainty about the value of X.
The entropy of a random variable represents the amount of uncertainty or randomness associated with the outcome of the variable. To calculate the entropy of a discrete random variable, we need to determine the probability distribution function and use the formula:
H(X) = -Σ P(X=x) log2(P(X=x))
In this case, the random variable X represents the number of defective chips in 5 randomly chosen chips from a box of 50, with 3 defective chips. The possible outcomes are 0, 1, 2, 3, and 4, with probabilities:
P(X=0) = (47/50)^5
P(X=1) = (5 * (3/50) * (47/50)^4)
P(X=2) = (10 * (3/50)^2 * (47/50)^3) / 2!
P(X=3) = (5 * (3/50)^3 * (47/50)^2) / 3!
P(X=4) = (3/50)^4 / 4!
By plugging in the probabilities into the entropy formula, we can find the entropy in bits.

You have 2 different savings accounts. For Account A, the simple interest earned after 6 months is $3.30. For Account B, the simple interest earned after 30 months is $37.50. If the interest rate is 3.3% for Account A and 2.5% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer
Answers
Principal amount in each account is $200 for Account A and $600 for Account B. Simple interest is most earned for Account B.
What is Simple Interest?Simple interest is defined as the interest obtained over the principal amount on a certain rate.
Simple interest is calculated by the formula,
SI = P × r × t,
where P is the principal amount, r is the interest rate and t is the time in years.
Account A :
t = 6 months = 0.5 year
S.I = $3.30
r = 3.3% = 0.033
Substituting in the formula,
3.30 = P × 0.033 × 0.5
P = 200
Principal amount in Account A is $200.
Simple interest earned in the first month = 200 × 0.033 × (1/12) = $0.55
Account B :
t = 30 months = 2.5 years
S.I = $37.50
r = 2.5% = 0.025
Substituting in the formula,
37.50 = P × 0.025 × 2.5
P = 600
Principal amount in Account B is $600.
Simple interest earned in the first month = 600 × 0.025 × (1/12) = $1.25
Account B earned more interest in the first month.
Hence Account B earned most interest in the first month with am amount of $1.25.

What is the velocity?Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.
Suppose a product's revenue function is given by R(q) = -7q² + 600q,
where R(q) is in dollars and q is units sold.
We have to determine a numeric value for the marginal revenue at 29 units
As per the question we have
R(q) = -7q² + 600q
Substitute the value of q = 29, and we get
R(29) = -7(29)² + 600(29)
R(29) = 11513
Thus, the Marginal Revenue MR(29) 11513 dollars per unit
Let s(t) = 8t³ - 48t² - 120t be the equation of motion for a particle.
To find the velocity, we need to differentiate the equation for the position of the particle, s(t).
v(t) = ds/dt = d/dt (8t³ - 48t² - 120t) = 24t² - 96t - 120
To find the t-values where the velocity is equal to zero, we need to set v(t) equal to zero and solve for t.
0 = 24t² - 96t - 120
This is a quadratic equation, and we can solve for t by factoring the GCF
(t - 5)(t + 1) = 0
(t - 5) = 0 and (t + 1) = 0
t = 5 and t = -1
So the velocity equals zero at t = 5
To find the acceleration, we need to differentiate the velocity function, v(t).
a(t) = dv/dt = d/dt (24t² - 96t - 120) = 48t - 96
So the acceleration of the particle is a(t) = 48t - 96.

You are given an integer N. You have to present Nas a sum of K distinct odd integers. Choose the relations of Kto Nwhich will make this impossible. Note: The % sign is the modulo operator.Pick ONE OR MORE optionsK*K>NN6K-OKK & NN62 # K%2
Answers
K * K > N, because if the square of K is greater than N, it is not possible to add K distinct odd integers to get N.
If you square an integer (multiply it by itself), the result will always be an even number. If K is an odd number, then K * K will be an odd number plus one, which makes it even.
For example, if K = 3, then K * K = 9, which is an even number. If we take the square root of 9, we get 3, which is K. This means that the square of K will always be greater than K itself.
Now, if we want to add K distinct odd integers to get N, then N must be greater than K * K. This is because the sum of K odd numbers will always be less than K * K, and we need N to be greater than this sum.
Therefore, if K * K > N, it means that it is not possible to add K distinct odd integers to get N, because N is smaller than K * K, and the sum of K odd numbers will be smaller than N.

find two negative and three positive angles, expressed in radians, for which the point on the unit circle that correspond to each angle
Answers
Two negative angles in radians are -π/2 and -π.
To find the points that correspond to these angles, we can use the formula: (cos θ,sin θ). For -π/2, this yields (0, -1) and for -π, this yields (-1, 0).Two negative angles in radians are -π/2 and -π.
Three positive angles in radians are 0, π/4 and π/2. For 0, the point is (1, 0); for π/4, the point is (0.707, 0.707); and for π/2, the point is (0, 1). To calculate these points, we can use the same formula, (cos θ,sin θ). For 0, this yields (1, 0); for π/4, this yields (cos π/4, sin π/4) = (0.707, 0.707); and for π/2, this yields (0, 1).
