Answer:
(A) 5^3 * 5^-4
= 5^(3-4)
= 5^(-1)
= 5^-1
= 1/5^1
= 0.2
Yes, expression has value between 0 and 1
(B) 3^5 / 3^-6
= 3^5 * 3^6
= 3^(5+6)
= 3^(11)
= 177147
No, expression does not have value between 0 and 1
(C) (1/4)^3 * (1/4)^2
= (1/4)^(3+2)
= (1/4)^(5)
= (1^5/4^5)
= 1 / 4^5
= 1 / 1024
= .000977
Yes, expression has value between 0 and 1
(D) (-7)^5 / (-7)^7
= (-7)^5 * (-7)^-7
= (-7)^(5-7)
= (-7)^(-2)
= 1 / (-7)^2
= 1 / 49
= 0.02041
Yes, expression has value between 0 and 1
Step-by-step explanation:
For these problems we need to know a few things:
(1) Powers of like bases, you add the exponent
This means the following:
x^y * x^z = x^(y+z)
Or
x^y / x^z = x^(y-z)
(2) Negative powers can be swapped on the fraction to be positive
This means the following:
x^-y = 1 / x^y
Or
1 / x^-y = x^y
Using these two things, we can easily simplify all the expressions given.

Emily split up the area of a rectangle to help her solve the division equation 5{,}360 \div 5=?5,360÷5=?5, comma, 360, divided by, 5, equals, question mark.
She splits the rectangle into parts that are easy to divide by 555:
Area model split into 4 parts, each with a width of 5 units. From top to bottom the parts have a height of A units and an area of 5,000 square units; a height of B units and an area of 300 square units; a height of C units and an area of 50 square units; a height of D and an area of 10 square units. A brace labeled H spans the top 4 parts.
Answer:
s
Step-by-step explanation:
Emily used an area model for 5,360 ÷ 5 split a rectangle into four parts: A=1,000, B=60, C=10, and D=2 units and total area = 5,360 after division the answer is 1,072.
To solve the division equation 5,360 ÷ 5, Emily used an area model split into 4 parts, each with a width of 5 units. Let's use the information provided to find the values of A, B, C, and D.
The area of the first part is 5,000 square units, and its width is 5 units. Therefore, the height of this part (A) is:
A = Area / Width
A = 5,000 / 5
A = 1,000 units
The area of the second part is 300 square units, and its width is 5 units. Therefore, the height of this part (B) is:
B = Area / Width
B = 300 / 5
B = 60 units
The area of the third part is 50 square units, and its width is 5 units. Therefore, the height of this part (C) is:
C = Area / Width
C = 50 / 5
C = 10 units
The area of the fourth part is 10 square units, and its width is 5 units. Therefore, the height of this part (D) is:
D = Area / Width
D = 10 / 5
D = 2 units
Now, we have the following values:
A = 1,000 units
B = 60 units
C = 10 units
D = 2 units
To find the total area of the rectangle, we sum up the areas of all four parts:
Total Area = 5,000 + 300 + 50 + 10 = 5,360 square units
Now, we can calculate the division 5,360 ÷ 5:
5,360 ÷ 5 = 1,072
Therefore, using area model the answer to the division equation is 1,072.

A2. Find y' and y" for y^2 = x^2
+ sinxy
Answer:
y' = (2x + y cosxy)/(2y + x cosxy)
Step-by-step explanation:
Using implicit differentiation:
y^2 = x^2 + sin xy
2y y' = 2x + cos xy * (xy' + y)
2y y' = 2x + xy' cos xy + y cos xy
2y y' - xy' cosxy = 2x + ycos xy
y' = (2x + y cosxy)/(2y - x cosxy)

divide 81 -x^2 y^2 by (9-xy) (3 + xy)
Answer:
When we divide 81 -x²y² by (9-xy) (3 + xy), we determine the expression is:
[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{9+xy}{3+xy}[/tex]
Step-by-step explanation:
Let us divide 81 -x²y² by (9-xy) (3 + xy)
so
Given the expression
[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}[/tex]
Factor -x²y² + 81 = (9+xy) (9-xy)
[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{\left(9+xy\right)\left(9-xy\right)}{\left(9-xy\right)\left(3+xy\right)}[/tex]
Cancel the common term: 9-xy
[tex]=\frac{9+xy}{3+xy}[/tex]
Therefore, when we divide 81 -x²y² by (9-xy) (3 + xy), we determine the expression is:
[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{9+xy}{3+xy}[/tex]

Which of the following statements about a negatively skewed distribution is true? a) The distribution of the data tails to the right of the median. b) The mean and median have the same value. c) The distribution of the data tails to the left of the median. d) The distribution of the data features two modes.
Answer: c) The distribution of the data tails to the left of the median
Step-by-step explanation:
In a scenario whereby the mean is more than the mode for a particular distribution, we can say that such distribution is said to be positively skewed.
Also, when the mean in the distribution is less than the mode, we can say that the distribution is said to be negatively skewed. For a negatively skewed distribution, it should be noted that on the left side, the tail of distribution is seem to be longer.
Therefore, the correct option is C "The distribution of the data tails to the left of the median".
The option C is correct.
Negatively skewed distribution:It is a type of distribution in which more values are concentrated on the right side of the distribution graph while the left tail of the distribution graph is longer.In a distribution that is negatively skewed, the mean of negatively skewed data will be less than the median. The distribution of the data tails to the left of the median. A negative skew is generally not good.So that Option C is correct.

2(6 + 3n) - 4
i need the answer...
.....
Answer:
See below.
Step-by-step explanation:
2(6 + 3n) - 4 (Given)
12 + 6n - 4 (Distribute)
6n + 8 (Add like terms)
3n + 4 (Divide by a factor of 2)
In case you wanted to solve for n:
2(6 + 3n) - 4 = 0 (Given)
12 + 6n - 4 = 0 (Distribute)
6n + 8 = 0 (Add like terms)
6n = -8 (Substract on both sides)
n = -4/3 (Divide 6 on both sides)
