Answer:
2^(7/2)
Step-by-step explanation:
Here, we want to write 2√32 as a power with a rational exponent.
That would be 2 * √32
= 2 * 32^1/2
= 2 * 2^5(1/2)
= 2 * 2^5/2
According to law of indices, this becomes the following;
2^(1 + 5/2)
= 2^(7/2)
Find (x+y)^2 when (x-y)=5 and xy=24
Formula:
(a+b)^2 -(a-b)^2 =4ab
(7)
Answer:
(x + y)² = 121
Step-by-step explanation:
Using the identity
(x + y)² - (x - y)² = 4xy , then
(x + y)² - 5² = 4(24) , that is
(x + y)² - 25 = 96 ( add 25 to both sides )
(x + y)² = 121

-3 r + 3(r-2) = -2(r+6)
Answer:
r= -3
Step-by-step explanation:
-3 r + 3(r-2) = -2(r+6)
-3r+3r-6= -2r-12
-6= -2r-12
2r=6-12
2r= -6
r= -3

Please answer! Will give brainiest! Which of the following side lengths could form a right triangle? Circle all that apply
A. 3, 7, 10 B. 4, 9, 10 C. 5, 12, 13 D. 6, 8, 10
Answer:
C. 5, 12 and 13
D. 6, 8 and 10
Step-by-step explanation:
To see if three side lengths would give you a right triangle, you have to use the Pythagoras Theorem which is a² + b² = c², where c is the hypotenuse (longest side) and a and b are adjacent to the right angle.
A. 3² + 7² ≠ 10²
9 + 49 ≠ 100
58 ≠ 100
B. 4² + 9² ≠ 10²
16 + 81 ≠ 100
97 ≠ 100
C. 5² + 12² = 13²
25 + 144 = 169
169 = 169
D. 6² + 8² = 10²
36 + 64 = 100
100 = 100

Which function represents the transformation that moves figures to the right 3 units and down 7 units?
Answer:
A
Step-by-step explanation:
Adding positively to an x moves it right, and negative moves left. Adding to a y moves it up, and subtracting moves it down.
The transformation that moves figures to the right 3 units and down 7 units is A. (x, y) ⇒ (x + 3, y - 7)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).
A function that moves figures to the right 3 units and down 7 units can be represented by:
(x, y) ⇒ (x + 3, y - 7)

The bar graph shows the differences in a city’s rainfall from the historical average. What is the difference in rainfall between the wettest and the driest months? Write your answer as a decimal.
The difference in rainfall between the wettest and the driest months is inches.
Answer:
The difference is 3.97 inches of rainfall
Step-by-step explanation:
Here, we want the difference between the wettest and driest months.
From the question, we can see that the wettest month has a rainfall height of 2.3 inches
The driest month has a rainfall of -1.67 inches
So the difference between the two will be;
2.3 - (-1.67)
= 2.3 + 1.67 = 3.97 inches
Answer:
4.03
Step-by-step explanation:
Have to add 2.36 and 1.67 and it would be a positive.

Answer:
The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
A city starts with a population of 200,000 people in
2005. The population has been declining according to
the equation
P(t) = 200,000e-.08
where P is the population t years later. Approximately
when will the population be half the initial amount?
Answer:
200,000 and 2005 which cant theoretically be done be P(t) which would increase in the population which would most likely be from 2005 to 2020. so you cannot do this because imagine it as X=(Y)x the mass of population which would be defined as (P) which will also be represented as a probable and physical change in the number. but not only the number, but the population. being have of the initial amount which you will take the variable (P) and have the exact amount which would be the population. Which would theoretically recon as a positive ID of the population.-Cj

Mikes home street address number has 5 digits . Two digits have values of 50,000 and 200 . The digits in the ones place is 3 . The value of each of the other digits is ten times the value of the digits on its right . What is mikes home street address number ?
Answer: Mikes home street address number = 52233
Step-by-step explanation:
We need to make a 5 digit number such that
Two digits have values of 50,000 and 200 .
The digits in the ones place is 3 .
Now number is like 50,000 +x + 200 + y + 3 (ten thousand > thousand > Hundred > tens > ones )
Need values for : thousands place and tens place
The value of each of the other digits is ten times the value of the digits on its right .
thousands place value (x)= 200 x 10 = 2000
tens place value (y)= 3 x 10 =30
Required number = 50,000 +2000 + 200 + 30+ 3 = 52,233
∴Mikes home street address number = 52233
(14 POINTS!) Based On the information in the table, is the cost of the apples proportional to the weight of apples ?
Answer:
yes it is proportional, if you subtract 3.76 from 5.64 you get 1.88 then add 1.88 to each number to make sure it's right.
Answer:
The statement of whether the cost is proportional to the cost and weight of apples is: yes, it is proportional.
Step-by-step explanation:
From what I can find out from the graph, I would firstly likely want to see if there is a constant between each pound and cost. Meaning, I would want to see if there is a rule that is used throughout the table.
From what I had found out, the rule of this table is:
(x = pounds of apples)
(y = cost of apples)
y = 1.88x
This means that in order to get the 'y' value, also known as the cost of apples, we must multiply 1.88 to the 'x' values, pounds of apples.
This can be found by:
First, dividing 3.76 to 2, your quotient is: 1.88
[tex]\frac{3.76}{2}=1.88[/tex]
Then we need to see if this applies to the other terms as well by multiplying 1.88 to each 'x'
y = 1.88x
y = 1.88(3) = 5.64
y = 1.88(4) = 7.52
y = 1.88(5) = 9.4
You get the same vaule, which means that this is proportional to the table provided.
