Answer:
A:
[tex]5^3*5^{-4}=5^{3-4}=5^{-1}=\frac{1}{5}[/tex] (It is a value between 0 and 1.)
B:
[tex]\frac{3^5}{3^{-6}}=3^{5-\left(-6\right)}=3^{5+6}=3^{11}=177147[/tex] (It is not a value between 0 and 1.)
C:
[tex]\left(\frac{1}{4}\right)^3\cdot \left(\frac{1}{4}\right)^2=\left(\frac{1}{4}\right)^{3+2}=\left(\frac{1}{4}\right)^5=\frac{1^5}{4^5}=\frac{1}{1024}[/tex] (It is a value between 0 and 1.)
D:
[tex]\frac{\left(-7\right)^5}{\left(-7\right)^7}=\left(-7\right)^{5-7}=\left(-7\right)^{-2}=\frac{1}{\left(-7\right)^2}=\frac{1}{49}[/tex] (It is a value between 0 and 1.)

Simplify: [tex]\frac{1}{\sqrt{5}-\sqrt{7}+\sqrt{12}}[/tex]
Answers
Make use of the difference of squares identity,
[tex]a^2-b^2=(a-b)(a+b)[/tex]
Let [tex]a=\sqrt5-\sqrt7[/tex] and [tex]b=\sqrt{12}[/tex]. Then
[tex]\dfrac1{(\sqrt5-\sqrt7)+\sqrt{12}}\cdot\dfrac{(\sqrt5-\sqrt7)-\sqrt{12}}{(\sqrt5-\sqrt7)-\sqrt{12}}=\dfrac{(\sqrt5-\sqrt7)-\sqrt{12}}{(\sqrt5-\sqrt7)^2-(\sqrt{12})^2}=\dfrac{\sqrt5-\sqrt7-\sqrt{12}}{5-2\sqrt{35}+7-12}=-\dfrac{\sqrt5-\sqrt7-\sqrt{12}}{2\sqrt{35}}[/tex]
Now multiply the numerator and denominator by √(35):
[tex]-\dfrac{\sqrt5-\sqrt7-\sqrt{12}}{2\sqrt{35}}\cdot\dfrac{\sqrt{35}}{\sqrt{35}}=-\dfrac{(\sqrt5-\sqrt7-\sqrt{12})\sqrt{35}}{70}=-\dfrac{5\sqrt7-7\sqrt5-2\sqrt{105}}{70}[/tex]
Answer:
Multiply the numerator and denominator by the conjugate.

Answers
Answer:
1= 1 7/36
2= 1/2
Step-by-step explanation:
1.) 7/9+5/12
find the LCM of 9 and 12
LCM= 36
(7/9 x 4/4) + (5/12 x 3/3)
28/36+15/36
= 43/36
Divide 43 by 36 to make it a mixed fraction
1 7/36
2.) 21/24 - 3/8
find LCM of 24 and 8
LCM = 24
(21/24 x 1/1)+ (3/8 x 3/3)
21/24 + 9/24
30/24
Divide 30 by 24 to make it mixed fraction
= 1 6/24

Each graph shows two polygons ABCD and A'B'C'D'. In each case, describe a sequence of transformations that takes ABCD to A'B'C'D'.
Answers
Answer:
You have to go clockwise and 90 degrees and the rest is self explanatory. Hope I helped.
Step-by-step explanation:
The required transformation of the polygons ABCD to A'B'C'D' is 7 units right and a clockwise orientation.
Given that,
Each graph shows two polygons ABCD and A'B'C'D'. In each case, To describe a sequence of transformations that takes ABCD to A'B'C'D'.
A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,
Examples of the polygon, equilateral triangle, square, pentagon etc
Here,
Polygons ABCD is at the left side of the y-axis and after transformation is shifted to the right of the y-axis by 7 units as the Location of Point A and the Location of point B' is 7 units apart. And is also oriented to 90° clockwise.
Thus, the required transformation of the polygons ABCD to A'B'C'D' is 7 units right and a clockwise orientation.

Explain how you would use fraction bars to find the quotient of 10/12Divided by 4/6 what is the quotient
Answers
Answer:
11/4
Step-by-step explanation:
Draw one whole fraction bar. Next, draw 6 equal bars under it, since you are dividing by sixths. Then draw a twelfths fraction bar with 2 twelfths for each sixth bar. Above the twelfths bar, circle groups of 4 sixths. There is one group of 4/6 with 1/6 remaining. Since 1/6 is 1/4 of 4/6, the quotient is 1 1/4.
