Answer:
The answer is "[tex]9a^4b^{10}(2+6a^6b^5)(2-6a^6b^5)[/tex]"
Step-by-step explanation:
For point a:
[tex]36a^4b^{10} - 81a^{16}b^{20}[/tex] by GCF
Calculating the const terms:[tex]36 \ n \ 81, \ GCF \ is\ 9\times 4 \ n \ 9\times 9[/tex]
Calculating the terms [tex]w\ a: a^4 \ n \ a^{16},\ GCF \ is\ a^4 \ n \ a^4 \times \ a^{12}[/tex]
Calculating the terms [tex]w \ b: b^{10}\ n\ b^{20}, \ GCF \ is\ b^{10}\ n \ b^{10} \times b^{10}[/tex]
Including the GCFs, [tex]36a^4 b^{10} - 81a^{16}b^{20}[/tex]
[tex]=9a^4b^{10}(4 - 9a^{12}b^{10})\\\\4=2^2 n 9a^{12}b^{10}\\\\=(3a^6b^5)^2[/tex]
Calculating the difference of squares
[tex]\to A^2 - B^2 = (A+B)(A-B)\\\\\to 4 - 9a^{12}b^{10} \\\\\to (2+3a^6b^5)(2-3a^6b^5)\\\\[/tex]
substituting
[tex]\to 36a^4b^{10} - 81a^{16}b^{20}\\\\\to 9a^4b^{10}(2+3a^6b^5)(2-3a^6b^5)[/tex]
For point b:
Calculating the difference of squares:
[tex]A^2 - B^2 = (A+B)(A-B)\\\\36a^4b^{10}=(6a^2b^5)^2\\\\81a^{16}b^{20}=(9a^8b^{10})^2\\\\36a^4b^{10} - 81a^{16}b^{20}\\\\=(6a^2b^5+9a^8b^{10})(6a^2b^5-9a^8b^{10})\\\\=3a^2b^5(2+6a^6b^5)3a^2b^5(2-6a^6b^5)\\\\=9a^4b^{10}(2+6a^6b^5)(2-6a^6b^5)[/tex]

If the graph of the quadratic parent function q(x) = x2 is translated 3 units to the right and 2 units down, which of the following equations describes the translated graph?
Answer:
s(x) = (x - 3)^2 - 2
Step-by-step explanation:
q(x) = x^2 becomes r(x) = (x - 3)^2 after a 3-units-to-the-right translation.
This, in turn, becomes s(x) = (x - 3)^2 - 2, after a 2-units-down translation.
Next time, please share the answer choices. Thank you.

Mayra bought a pair of sneakers. They originally cost $75 but were on sale for 15% how much mony did she save
Answer: $11.25
Step-by-step explanation:
Since the sneakers were on sale for 15% less, the amount she bought them will be:
= (100% - 15%) × $75
= 85% × $75
= 0.85 × $75
= $63.75
Therefore, the amount she saved will then be:
= $75 - $63.75
= $11.25
She saved $11.25
Sasha order 3/5 of a pound of cheese .Each slice of cheese weighs 0.15 pounds. Enter the number of slices of cheese that Sasha will receive
Answer:
4. slices
Step-by-step explanation:
because If you turn 3/5 in to a decimal you get 0.6 and each slice of cheese weighs 0.15 so you do 0.6 divided by 0.15
Write a rule for g described by the transformations of the graph of f.
Let g be a horizontal shrink by a factor of 3/7, followed by a translation 5 units left
of the graph of f(x)=(21x)^1/2
Answer:[tex]g(x)=\frac{3}{7}(21(x+5))^{1/2}[/tex]
Step-by-step explanation:
Transformation rule:
Shifting by k units left : [tex]f(x)\to f(x+5)[/tex]
Dilation by a factor of h units: [tex]f(x)\to hf(x)[/tex]
Let g be a horizontal shrink by a factor of 3/7, followed by a translation 5 units left of the graph of [tex]f(x)=(21x)^{1/2}[/tex]
The rule for g described by the transformations of the graph of f. : [tex]g(x)=\frac{3}{7}(21(x+5))^{1/2}[/tex]

Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?
Answer:
25.55
Step-by-step explanation:
Let us take the number he thinked of be x .
On doubling it :-
→ N = 2x
On adding 19 :-
→ N = 2x + 19
According to Question :-
→ 2x + 19 = 70.1
→ 2x = 70.1 - 19
→ 2x = 51.1
→ x = 51.1/2
→ x = 25.55
Hence the required answer is 25.55Help I don’t know how to do this

find the slope between (-3,2) and (-7,-16)
Answer: The slope between these two is 3.5
Answer:
Solpe=4.5
Step-by-step explanation:
Sorry if I’m wrong, but I think I got it.
So the formula for slope is y2-y1/x2-x1
In (-3,-2) )-7,-16), -3 is x1, -2 is y1, -7 is x2, and -16 is y2.
Now, you need to fill in the formula with these numbers.
-16-2/-7- - 3
-16-2 is -18
-7- - 3 is -4 (two negatives make a positive)
This makes -18/-4. Divide this to get 4.5.

Sin0=20/29 find tan 0
Answer:
Step-by-step explanation:
here opposite =20, hypotenuse=29
to find adjacent use formula
a^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
b^2=841-400
b=[tex]\sqrt{441\\}[/tex]
b=21
tan theta=opposite/adjacent
=20/21
therefore tan theta =20/21
Answer:
D. tanθ = 20/21
Step-by-step explanation:
Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.
To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.
When you plug in your values and solve for the other leg, you'll get 21.
Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.
Opposite = 20
Adjacent = 21
tanθ = 20/21

4 cans of orange juice and 7 cans of apple juice are in a sports bags what is the probability of drawing out one can of apple juice without looking? write your answer as a decimal rounded to two decimal places.
Answer:
1.36
total cans =11
the prob. of drawing orange juice can= 4/11
the prob of drawing apple juice can= 7/11
the prob of drawing any of the juice= 4/11 + 7/11
= 15/11
= 1.36
