Answer: HCF =
x³y
Step-by-step explanation:
HCF of ax³y and bx⁴y³
ax³y = a . x . x . x . y
bx⁴y³ = b . x . x . x . x . y . y . y
Common Factors = x . x . x . y
HCF = x . x . x . y
HCF = x³y Answer
therefore, the HCF of ax³y and bx⁴y³ is x³y.

If AD = 24, DB = 27 and EB = 18, find CE.
The length of side of triangle portion CE is 16.
What are similar triangles?When two triangles forms on the same base, has its other two sides in proportional with each other, the triangles are known as the similar triangles.
Given, the dimensions AD = 24, DB = 27 and EB = 18.
In the given diagram of two similar triangles, ABC and DBE
DB/AD = EB/CE
Substitute the values, we get
27/24 = 18/CE
CE= 16
Thus, the value of CE = 16

What is the product of the polynomials below? (3x^3+9x)(x^2-2)
Answer:
= 3x⁵ + 3x³ - 18x
Step-by-step explanation:
(3x³ + 9x)(x²-2)
= 3x³ * x² + 3x³ * -2 + 9x * x² + 9x * -2
= 3x⁵ - 6x³ + 9x³ - 18x
= 3x⁵ + 3x³ - 18x
This season, the probability that the Yankees will win a game is 0.52 and the
probability that the Yankees will score 5 or more runs in a game is 0.53. The
probability that the Yankees lose and score fewer than 5 runs is 0.39. What is the
probability that the Yankees will lose when they score 5 or more runs?
Answer:
The probability of scoring fewer than 5 runs when they win is P = 0.19
How to find the probability?
We know that:
The probability of winning a game is p = 0.53
The probability of scoring 5 or more runs is q = 0.59
The probability of winning and scoring 5 or more runs is k = 0.43
Notice that the joint probability is different than the product of the individual probabilities, this means that the events are not independent.
So, we know that the probability of winning is 0.53
Now, given that they win, the probability of scoring 5 or more times will be q' such that:
0.53*q' = 0.43
q' = 0.811
This means that when they win, the probability of scoring more than 5 times is 0.81
Then the probability of scoring less than 5 times when they win is 1 minus the above probability:
P = 1 - 0.81 = 0.19
The probability of scoring fewer than 5 runs when they win is P = 0.19

Answer:
1.64
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6.6^2 + x^2 = 6.8^2
43.56+x^2=46.24
Subtract 43.56 from each side
x^2 = 46.24-43.56
x^2 =2.68
Take the square root of each side
sqrt(x^2) = sqrt(2.68)
x =1.637080554
To 3 significant digits
x = 1.64
Answer:
Step-by-step explanation:
x = 1.637 mm
Pythagorean theorem:We can use Pythagorean theorem, to find the unknown side for a right angled triangle.
The side opposite to 90 is the longest side and it is the hypotenuse.
Base² + altitude² = hypotenuse²
x² + 6.6² = 6.8²
x² + 43.56 = 46.24
x² = 46.24 - 43.56
x² = 2.68
x = √2.68
[tex]\sf \boxed{\bf x = 1.637 \ mm }[/tex]

B. (p-7q) (p² +7pq+49q²)
C. (p² +7q) (p³ +49pq+7q²)
D. The polynomial is irreducible.
Answer:
B
Step-by-step explanation:
a difference of cubes factors in general as
a³ - b³ = (a - b)(a² + ab + b²)
