Answer:
9(8d + 9)
Step-by-step explanation:
Since 72 and 81 are both divisible by 9, we can factor out a 9 from the expression:
72d + 81
9(8d + 9)
So, the factored expression is 9(8d + 9)
How do you check if a function has an inverse function?
We can check if a function has an inverse function using horizontal Line Test.
What is Function?

Answer:
x = 4
y = 28
Step-by-step explanation:
1) y = 7x
2) y = 2x + 20
substitute y = 7x into equation 2:
7x = 2x + 20 now you can solve for x:
7x - 2x = 20
5x = 20
x = 20/5 = 4
Plug x = 4 into either equation 1 or 2 to solve for y:
y = 7x = 7(4) = 28

HELP PLEASE How many combinations are possible to select a student president, vice president, and treasurer among 23 students? Assume a student cannot hold more than one office.
Answer:

Step-by-step explanation:
Because being the student president is different from being the treasurer, the order in which students are selected for these roles matters. Therefore, a permutation is used to calculate the number of combinations that are possible, with nPr = n/(n-r) or evaluate it by doing 23c3.
What is the AAA theorem?
According to the Angle-Angle-Angle (AAA) criterion, "if in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion), and hence the two triangles are identical."
Proof:
Consider two triangles ABC and DEF, such that ∠A = ∠D, ∠B = ∠E, and ∠C = ∠F
Now, cut DP= AB and DQ= AC and join PQ. Hence, we can say that a triangle ABC is congruent to the triangle DPQ.
(i.e) ∆ ABC ≅ ∆ DPQ, which gives ∠B = ∠P = ∠E, and also, the line PQ is parallel to EF.
Therefore, by using the basic proportionality theorem, we can write
DP/PE = DQ/QF.
(i.e) AB/DE = AC/DF. …(1)
Similarly,
AB/DE = BC/EF …(2)
From (1) and (2), we can write:
AB/DE = BC/EF = AC/DF.
Therefore, the two triangles ABC and DEF are similar.

The graph of the function g(x) is added as an attachment
How to plot the graph of the functionFrom the question, we have the following parameters that can be used in our computation:
f(x) equals log2 x
Express the equation properly
So, we have
f(x) = log₂(x)
Also, we have
g(x) = -log₂(x - 3)
The transformation from f(x) to g(x) is that:
f(x) is shifted right by 3 unitsf(x) is reflected across the x-axisThis means that
g(x) = -f(x - 3)
So, we apply the above transformations on the graph of f(x) to form g(x)

The length, breadth and height of a cuboidal tank is 4m, 2m and 0.75 m respectively. What is the capacity of the tank
The cuboidal tank has a volume of [tex]6m^3[/tex] with dimensions of 4 m in length, 2 m in width, and 0.75 m in height.
How can I determine a cuboidal tank's capacity?The total amount of room or volume that a cuboidal tank can hold is known as its capacity. By multiplying the tank's length, width, and height collectively, it is determined.
The tank in this instance measures 4 metres long, 2 metres wide, and 0.75 metres high. We must multiply these three parameters collectively to determine the tank's capacity:
[tex]4m * 2m * 0.75m = 6m^3[/tex]
The tank can therefore hold [tex]6m^3[/tex] of liquid.

Answer:
30 sheep
Step-by-step explanation:
The first section has 90 sheep sorted into 3 rows. How many sheep are
in each row of the first section?
From the above question:
3 rows = 90 sheep
1 row = x

We can subtract the fixed 12 of 40 to see how much she can spend on messages alone. So we are left with $28.
At 10 cents apiece for every dollar she can send 10. So we would get 280 messages.

Captain Kevin has a ship, the H. M. S. Khan. The ship is two furlongs from the dread pirate Ben and his merciless band of thieves. The Captain has probability \dfrac{3}{5} 5 3 of hitting the pirate ship. The pirate only has one good eye, so he hits the Captain's ship with probability \dfrac{1}{5} 5 1 . If both fire their cannons at the same time, what is the probability that the Captain hits the pirate ship, but the pirate misses?
Probability that the Captain does NOT hit the pirate's ship × Probability that the pirate hits the Captain's ship = (2/5) × (1/5) = (2/25) = 0.08
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true.
The probability that the pirate hits the Captain's ship, but the Captain misses
= 2/25) = 0.08
P(C) = (3/5) is the likelihood that the captain will strike the pirate ship.
P(C') = 1 - (3/5) = (2/5) is the probability that the captain will miss the pirate ship.
P(p) = (1/5) is the likelihood that the pirate will sink the captain's vessel.
P(p') = 1 - (1/5) = (4/5) is the probability that the pirate will miss the captain's ship.
The likelihood that the pirate will hit the captain's ship while the captain misses is increased if they both fire their cannons at the same moment.
P(C' n p) is he needed probability.
P(C' n p) = P(C') P since the two events are independent of one another (p) The likelihood that the pirate will sink the captain's vessel but that the capain will miss = (Chance that the Captain misses the pirate's ship) (Chance that the pirate hits the Captain's ship) = (2/5) × (1/5) = (2/25) = 0.08

What is the difference of the two polynomials 9x2 8x 2x2 3x?
The difference between the polynomials 9x² + 8x and 2x² + 3x is 7x² + 5x.
What is polynomials?A polynomial is formed mathematically by combining one or more algebraic terms (monomials). The roots of "polynomial" are poly- (many) and -nomial (terms). A polynomial can have exponents (powers), constants (numbers), and variables (letters), but not negative exponents or variable division.
Polynomials are typically expressed in standard form. Furthermore, because there are no similar terms among the exponents, they are arranged in descending order (largest to smallest).
To find the difference between
(9x² + 8x) - (2x² + 3x)
We do calculation
= 9x² + 8x - 2x² - 3x
= 9x² - 2x² + 8x - 3x
= 7x² + 5x
Thus, the difference between the polynomials is 7x² + 5x.

Which is the algebraic sequence of 1,4,7,10
The algebraic sequence of 1,4,7,10 is aₙ = 3n - 2
How to determine the explicit formula of the sequence?From the question, we have the following sequence that can be used in our computation:
1,4,7,10
In the above sequence, we can see that 3 is added to the previous term to get the current term
Using the above as a guide,
So, we have the following representation
aₙ = aₙ₋₁ + 3
Also, we have
a = 1 i.e. the first term
d = 3 i.e he common difference
When represented explicitly, we have
aₙ = a + (n - 1) * d
So, we have
aₙ = 1 + (n - 1) * 3
Evaluate the products
aₙ = 3n - 2
Hence, the explicit formula is aₙ = 3n - 2
