The equivalent expression using laws of exponents gives us; 2 over quantity 9 times d raised to the negative fourteenth power end quantity
How to use laws of exponents?
We want to write an equivalent expression for 4 times d raised to the negative fifth power all over quantity 18 times d raised to the ninth power end quantity. This can be expressed as;
4d⁻⁵/18d⁹
Now, according to laws of exponents, we know that;
x²/x³ = x²⁻³ = x⁻¹
Applying that law to our question gives us;
4d⁻⁵/18d⁹ = (4/18)(d⁻⁵⁻⁹)
= (4/18)(d⁻¹⁴)
Now, the expression 4/18 can be broken down to 2/9. Thus, our final expression is; ²/₉d⁻¹⁴
Writing that in words gives;

cinnamon ___ dollars per pound
spice ____ dollars per pound
Answers
The cost per pound of the cinnamon tea and of the spice tea would be = cinnamon $31.76 dollars per pound
spice $58.24 dollars per pound.
How to calculate the cost of the two different teas?For the first mixture ;The volume of the cinnamon tea = 8 Ib
The volume of the spice tea = 6 Ib
The total volume of mixture = 14 Ib
For the second mixture:The volume of the cinnamon tea = 4 Ib
The volume of the spice tea = 16 Ib
The total volume of mixture = 14 Ib
Add the both constitutes of the mixture;
Total volume of cinnamon tea in both mixture = 8+4 = 12 Ib.
Total volume of spice tea in both mixture = 6+16 = 22 Ib
Total weight of the both mixture = 12+22 = 34 Ib
Total price for both mixture = 38+52 = $90
The cost of cinnamon alone;
= 12/34 × 90/1
= 1080/34
= $31.76
The cost of spice tea = 90- 31.76 = $58.24.

we have to fin the equation of the line that passes through the points (0, 0) and (8, 1) .
we know that the equation of the line in slope intercept form is written as
y = mx c , where m is slope of line .
and m(slope) between the points (a,b) and (c,d) can be found using the formula ,
slope = (d - b)/(c -a)
Substituting the values in the formula ,
we get ,
slope = (1-0)/(8-0)

Base case: 1 + 0 = 1, by the first recursive definition.
Induction step: Assume that 1 + n = n + 1, for some natural number n. Then, 1 + (n + 1) = (1 + n) + 1, by the second recursive definition. By the induction hypothesis, this is equal to (n + 1) + 1. Using the commutativity of addition (which can be proved from the Peano axioms), we can write this as n + (1 + 1), which is equal to n + 2 by the first recursive definition. Therefore, 1 + (n + 1) = n + 2, and the proof is complete.
Therefore, we have shown that 1 + 1 = 2, using the Peano axioms and mathematical induction.

A probability distribution refers to the mathematical function that provides the probabilities of occurrence of different possible outcomes for an experiment. Continuous probability distribution refers to a probability distribution with continuous types of data or random variables where the random variable can take on any value and is continuous. As there are infinite values that the variable can assume, the probability of the variable assuming any one specific value is zero.

Solve the following differential equations with Laplace transform method to find dy (t) / d(t). + 5y(t) = 2, y(0) = 2
Answers
Using the properties of the inverse Laplace transform, we get: y(t)=52L−1{s1}−52L−1{s+51}+L−1
The given differential equation is:
dtdy(t)+5y(t)=2
with the initial condition y(0)=2.
Taking the Laplace transform of both sides of the differential equation, we get:
sY(s)−y(0)+5Y(s)=s2
where Y(s) is the Laplace transform of y(t). Substituting the initial condition y(0)=2, we get:
(s+5)Y(s)−2=s2
Solving for Y(s), we get:
Y(s)=s(s+5)2+s+52
Taking the inverse Laplace transform of Y(s), we get:
y(t)=L−1{s(s+5)2}+L−1{s+52}
Using partial fraction decomposition, we can write:
s(s+5)2=sA+s+5B
Multiplying both sides by s(s+5) and solving for A and B, we get:
A=s→0lims+52=52
B=s→−5lims2=−52
Hence,
y(t)=L−1{5s2}−L−1{5(s+5)2}+L−1{s+52}
Using the properties of the inverse Laplace transform, we get:
y(t)=52L−1{s1}−52L−1{s+51}+L−1

A = 24
a = 9

h = ?
Lets plug all that in:
24 = 1/2(9+7)h

Answers
By using the ratio, we will see that angle C measures 36° and angle D measures 54°.
How to find the measure of the angles?First, two angles are complementary if the sum of their measures gives 90°.
So we have:
C + D = 90°.
Also, we know that the ratio of C to D is 2:3
This means that we can divide the 90° in 5 parts (3 + 2 = 5) such that 2 of these parts are angle C, and the remaining 3 are angle D.
90°/5 = 18°
C = 2*18° = 36°
D = 3*18° = 54°

Find the absolute extrema of the function on the closed interva 6x² X-2 minimum minimum maximum g(x) = (x, y) = (x, y) = (x, y) = LARCALC11 3.1.031. C [-2, 1] (smaller x-value) (large x+value)
Answers
The absolute maximum value of the function g(x) = 6x² - 2x on the interval [-2, 1] is 28 at x = -2, and the absolute minimum value is 1/6 at x = 1/6.
To find the absolute extrema of the function g(x) = 6x² - 2x on the closed interval [-2, 1], we need to evaluate the function at the critical points and the endpoints of the interval.
Critical Points:
To find the critical points, we need to find the values of x where the derivative of the function g(x) is equal to zero or undefined.
First, let's find the derivative of g(x):
g'(x) = d/dx (6x² - 2x)
= 12x - 2
To find the critical points, we set g'(x) = 0 and solve for x:
12x - 2 = 0
12x = 2
x = 2/12
x = 1/6
So, the critical point is x = 1/6.
Endpoints:
Next, we evaluate the function g(x) at the endpoints of the interval [-2, 1]:
g(-2) = 6(-2)² - 2(-2) = 24 + 4 = 28
g(1) = 6(1)² - 2(1) = 6 - 2 = 4
Now, we compare the values of g(x) at the critical point and the endpoints to find the absolute extrema:
g(1/6) = 6(1/6)² - 2(1/6) = 1/2 - 1/3 = 1/6
The maximum value is g(-2) = 28, and the minimum value is g(1/6) = 1/6.
Therefore, the absolute maximum value of g(x) on the interval [-2, 1] is 28, which occurs at x = -2, and the absolute minimum value is 1/6, which occurs at x = 1/6.

The equation log₂(x - 1) = x³ - 4x has one solution at x = 2.
To determine the solutions to the equation log₂(x - 1) = x³ - 4x, we can set the two expressions equal to each other:
log₂(x - 1) = x³ - 4x
Since we know that the graphs of the two functions intersect at the points (2, 0) and (1.1187, -3.075), we can substitute these values into the equation to find the solutions.
For the point (2, 0):
log₂(2 - 1) = 2³ - 4(2)
log₂(1) = 8 - 8
0 = 0
The equation holds true for the point (2, 0), so (2, 0) is one solution.
For the point (1.1187, -3.075):
log₂(1.1187 - 1) = (1.1187)³ - 4(1.1187)
log₂(0.1187) = 1.4013 - 4.4748
-3.075 = -3.0735 (approx.)
The equation is not satisfied for the point (1.1187, -3.075), so (1.1187, -3.075) is not a solution.
Therefore, the equation log₂(x - 1) = x³ - 4x has one solution at x = 2.

Answer: 56%
Step-by-step explanation: To write the fraction 28/50 as a percent, remember that a percent is a ratio that compares a number to 100.
So we need to find a fraction that's equivalent
to 28/50 that has a 100 in the denominator.
To do this, we set up a proportion.
So we have 28/50 = n/100.
To find the value of n, we first find the fraction that
is equivalent to 28/50 that has a denominator of 100.
If we multiply both the numerator and denominator of
28/50 by 2, we can see that 28/50 = 56/100.
