Answer:
A
Step-by-step explanation:
Given expression:
[tex]\sqrt[4]{768x^8y^5}[/tex]
Using rule [tex]\sqrt{ab} =\sqrt{a} \cdot \sqrt{b}[/tex]
[tex]=\sqrt[4]{768}\cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^5}[/tex]
Prime factorization of 768:
[tex]=\sqrt[4]{2^8\cdot3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^5}[/tex]
[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^5}[/tex]
Using rule [tex]a^{b+c}=a^ba^c[/tex] :
[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^{4+1}}[/tex]
[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^4y^1}}[/tex]
[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^4} \cdot\sqrt[4]{y}[/tex]
Using rule [tex]\sqrt[a]{b^c} =b^{\frac{c}{a}}[/tex] :
[tex]=2^{\frac84}} \cdot \sqrt[4]{3} \cdot x^{\frac84}\cdot y^{\frac44} \cdot \sqrt[4]{y}[/tex]
[tex]=2^2 \cdot \sqrt[4]{3} \cdot x^2\cdot y \cdot \sqrt[4]{y}[/tex]
[tex]=4 \cdot \sqrt[4]{3} \cdot x^2\cdot y \cdot \sqrt[4]{y}[/tex]
Gather like terms:
[tex]=4 \cdot x^2\cdot y\cdot \sqrt[4]{3} \cdot \sqrt[4]{y}[/tex]
[tex]=4x^2y \sqrt[4]{3y}[/tex]

Step-by-step explanation:
Based on the lengths of the segments in the ellipse below, how long is the major axis of the ellipse? Show your work.
Check the picture below.
the distances d1 and d2 are for this ellipse 7 and 3 respectively, keeping in mind that their sum is always the same, namely d1 + d2 is always the same 10 no matter where on the ellipse you move the point, notice in the picture, if we move d1 to the extent that lies flat right on top of d2, we have the length of d1 in purple, plus the length of d2, which we later colored in darkyellow, if we move d2 to the right-hand-side or the tail of d1, we'd end up with the ellipse's major axis, which is oddly enough, d1 + d2.

Step-by-step explanation:
x-4=12 What IS The Answer
Answer:
x = 16
Step-by-step explanation:
Add 4 to both sides, in order to isolate x:
x - 4 = 12
x = 16
So, x = 16

A triangle has sides with lengths of 6 feet, 16 feet, and 17 feet. Is it a right triangle?
Answer:
No.
Step-by-step explanation:
This is not a right triangle. Use the Pythagorean Theorem, [tex]a^{2} + b^{2}=c^{2} \\[/tex], but write it as [tex]c^{2}= a^{2}+b^{2}[/tex]. The hypotenuse would be 17 feet, so you can insert 17 as [tex]c^{2}[/tex]. [tex]a[/tex] and [tex]b[/tex] could be 6 or 16. It can be written either way. The simplified equation would be:
[tex]c^{2}=a^{2} +b^{2} \\17^{2} = 6^{2} + 16^{2} \\17^{2} = 36+ 256\\17^{2}= 292\\289\neq 292[/tex]
This isn't a right triangle.
I hope this helped :)

Work out the sizes of angles a, b and c. Give reasons for your answers.
Answer:
I think that you are wrong with that question
Answer:
a = 50° , b = 60° , c = 70°
Step-by-step explanation:
a and 130° are adjacent angles on a straight line and sum to 180° , then
a = 180° - 130° = 50°
b and 60° are vertically opposite angles and are congruent , so
b = 60°
the sum of the 3 angles in a triangle = 180° , that is
a + b + c = 180°
50° + 60° + c = 180°
110° + c = 180° ( subtract 110° from both sides )
c = 70°
2(5x + 3x2 -4) - (6x - 9)
Answer: X=3
Step-by-step explanation:
and the answer to the problem is 4x+13
Answer: 4x+13
Solution Steps
2(5x+3×2−4)−(6x−9)
Multiply 3 and 2 to get 6.
2(5x+6−4)−(6x−9)
Subtract 4 from 6 to get 2.
2(5x+2)−(6x−9)
Use the distributive property to multiply 2 by 5x+2.
10x+4−(6x−9)
To find the opposite of 6x−9, find the opposite of each term.
10x+4−6x−(−9)
The opposite of −9 is 9.
10x+4−6x+9
Combine 10x and −6x to get 4x.
4x+4+9
Add 4 and 9 to get 13.
4x+13

4x+2=4x+2
Step-by-step explanation:
Write the equation of the line that passes through the points (-6,6) and (7,7)
Answer:
y = 1/13 x + 84/13 or 13y = x + 84
Step-by-step explanation:
m = (y2 - y1) / (x2 - x1)
= (7 - 6) / [(7 - (-6)]
= 1 / 13
Solve for b. Use (-6, 6)
y = mx + b
6 = 1/13 (-6) + b
6 = -6/13 + b
6 + 6/13 = b
84/13 = b
Substitute the m and b:
y = mx + b
y = 1/13 x + 84/13 or 13y = x + 84

There is a rope running from the
top of a flagpole to a hook in the
ground. The flagpole is 6 meters
high, and the hook is 8 meters
from its base. How long is the
rope?
Can someone help me pls!
Answer:
The length of the rope = 8.94 meters
Step-by-step explanation:
The flagpole is 8 meters high
The hook is 4 meters from its base and the hook is in the ground
The flagpole and the ground ⊥ to each other
By using Pythagoras theorem:
The length of the rope = √(8² + 4²) = 5√5 = 8.94 meters

Answer:
first, you would divide because P.E.M.D.A.S. so 6/4=1.5 then you would add 12 making it 13.5 and -3 is 10.5
Step-by-step explanation:
mr clean
Answer:
10.5
Step-by-step explanation:
Using PEMDAS,
12 + 6 / 4 - 3
12 + 1.5 - 3
13.5 - 3
= 10.5
Solve for X, and show the equation you would use to solve.
Opposite interior angles are equal, so
4x - 10 = 2x + 20
2x - 10 = 20
2x = 30
x = 15
Answer:
4x-10=2x+20(being alternate angle)
or,4x-2x=20+10
or,2x=30
or,x=30/2
or,x=15
again,
4x-10 (putting the value of x)
=4×15-10
=60+10
=70
2x+20 (putting the value of x)
=2×15+20
=30+20
=50

Answer:
4
Step-by-step explanation:
40 - (18÷3)²
40 - (6)²
40 - 36
4
i think this is right
Answer:
(b) Jo answered 4 which is the right answer.
Step-by-step explanation:
First, you have to remember PEMDAS which is parentheses, exponents, multiplication, division, addition, and subtraction.
In this case, you need to do 18/3 first because that is in the parentheses which always goes first.
Your answer should be 6 and you should write the question like this:
40-(6)^2
Now, you need to do the exponent next which is 6x6 not 6x2.
Remember, exponents, are the base which is the number 6 multiplied by itself to that many times so in this case, our base is 6 and the exponent says we need to have 6 multiplied to itself 2 times. 6x6
We like to say 6 to the power of 2 is 36.
So now you need to write the simplified equation to this:
40-36=n
Our n variable is a placeholder for our answer.
Now it's basic subtraction which is 40-36 = 4
Therefore, Jo had the right answer.
