Espress 15 x^1/2 y^1/5 using a radical
Answer:
The correct answer is C. 15 ¹⁵√x⁵y³
Correct question and statement:
Express 15x^1/3 y^1/5 using a radical, as it is written in the graph attached.
Step-by-step explanation:
15x^1/3 y^1/5
15 * (x^1/3 y^1/5)
For multiplying two fractional exponents with different bases, we need to equal the denominator of the fractional exponents.
Therefore, we have:
1/3 * 5/5 = 5/15 ⇒ 1/5 * 3/3 = 3/15
15 * (x^5/15 y^3/15)
Now we can express the fractional exponents as an only radical, this way:
x^a/b = ᵇ√xᵃ
15 * ¹⁵√x⁵y³
The correct answer is C. 15 ¹⁵√x⁵y³

Annabeth, Grover, and Percy are shopping. Together, Annabeth and Grover have $43. If Grover and Percy combine their money, they have $55. Percy has $7 more than Grover. How much does each person have?
Answer:
Grover has $24, Percy has $31 and Annabeth has $19.
Step-by-step explanation:
Create equations to represent the situation.
let a be Annabeth
let g be Grover
let p be Percy
a + g = 43 Together, Annabeth and Grover have $43
g + p = 55 If Grover and Percy combine their money, they have $55
p = g + 7 Percy has $7 more than Grover
See if any of the equations can be combined. For example, we know p is g+7.
Substitute p for g+7 in an equation that has the variable p.
g + p = 55
g + g + 7 = 55 Combine like terms (g)
2g + 7 = 55 Start isolating g. Subtract 7 from both sides
2g = 55 - 7
2g = 48 Divide both sides by 2
g = 48/2
g = 24 Money Grover has
Use the equation p = g + 7. Find "p" by substituting g for 24.
p = g + 7
p = 24 + 7 Add
p = 31 Money Percy has
Substitute g for 24 in the last equation, a + g = 43, to find a.
a + g = 43
a + 24 = 43 Subtract 24 from both sides
a = 43 - 24
a = 19 Money Annabeth has
Therefore Grover has $24, Percy has $31 and Annabeth has $19.
Answer:
Grover has $24, Percy has $31 and Annabeth has $19.

Substitute p for g+7 in an equation that has the variable p.
g + p = 55
g + g + 7 = 55 Combine like terms (g)
2g + 7 = 55 Start isolating g. Subtract 7 from both sides
2g = 55 - 7
2g = 48 Divide both sides by 2
g = 48/2
g = 24 Money Grover has
Use the equation p = g + 7. Find "p" by substituting g for 24.
p = g + 7
p = 24 + 7 Add
p = 31 Money Percy has
Substitute g for 24 in the last equation, a + g = 43, to find a.
a + g = 43
a + 24 = 43 Subtract 24 from both sides
a = 43 - 24

When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 2 kg, the acceleration of the object is 35 /ms2. When the same force acts upon another object, its acceleration is 10 /ms2. What is the mass of this object?
Answer:
7 kg
Step-by-step explanation:
F=35*2=m*10
70=10m
7=m
The mass of the second object is 7 kg
First, we make the following representations
[tex]F \to[/tex] Force
[tex]a \to[/tex] acceleration
[tex]m \to[/tex] mass
The formula of force is:
[tex]F = m * a[/tex]
Since force is constant, then:
[tex]m_1 =2kg[/tex] [tex]a_1 = 35m/s^2[/tex] --- subset 1 represents the first object
[tex]m_2 = ??[/tex] [tex]a_2 = 10m/s^2[/tex] --- subset 2 represents the second object
We are to calculate the mass of the second object
A constant force means:
[tex]m_1 * a_1 = m_2 * a_2[/tex]
Make m2 the subject
[tex]m_2 = \frac{m_1 * a_1}{a_2}[/tex]
Substitute known values
[tex]m_2 = \frac{2kg * 35m/s^2}{10m/s^2}[/tex]
[tex]m_2 = \frac{2kg * 35}{10}[/tex]
[tex]m_2 = \frac{70kg}{10}[/tex]
[tex]m_2 =7kg[/tex]
Hence, the mass of the second object is 7kg

please I need a good step by step explanation I try to resolved it but I can't do it
Answer:
The % of the increase in population from 1980 to 2000 will be 72.8%
Step-by-step explanation:
Let the population in the year of 1980 was x.
If the population from 1980 to 1990 has increased by 20%, then the population in the year 1990 will be [tex]x(1 + \frac{20}{100}) = 1.2x[/tex].
Now, from 1990 to 2000, the population has again increased by 20%.
So, the population in the year 2000 will be [tex]1.2x(1 + \frac{20}{100}) = 1.44x[/tex].
Again, from 2000 to 2010, the population has increased by 20%.
Therefore, the population in the year 2010 will be [tex]1.44x(1 + \frac{20}{100}) = 1.728x[/tex].
Now, the population increased from x to 1.728x between the years 1980 to 2010.
Hence, the % of the increase in population from 1980 to 2000 will be [tex](\frac{1.728x - x}{x}) \times 100\% = 72.8\%[/tex] (Answer)

PLZZZ HELP
Answer:
[tex]A=65.97\ cm^2[/tex]
Step-by-step explanation:
The complete question is
The shaded region is the area outside the smaller circle and inside the larger circle
we know that
The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
so
The area of the shaded region is
[tex]A=\pi [r_1^2-r_2^2][/tex]
where
[tex]r_1=12.5/2=6.25\ cm[/tex] ---> radius of the larger circle (is half the diameter)
[tex]r_2=8.5/2=4.25\ cm[/tex] ---> radius of the smaller circle (is half the diameter)
assume
[tex]\pi =3.1416[/tex]
substitute
[tex]A=3.1416[(6.25)^2-(4.25)^2][/tex]
[tex]A=65.97\ cm^2[/tex]
Which of the following is an odd function?
f(x) = x3 + 5x2 + x
O F(x)= √x
Of(x) = x2 + x
O f(x) = -x
Option 4
f(x) = -x is an odd function
Solution:
A function is odd if and only if f(–x) = –f(x)
Option 1
[tex]f(x) = x^3 + 5x^2 + x[/tex]
Substitute x = -x in above equation
[tex]f(-x) = (-x)^3 + 5(-x)^2 + (-x)[/tex]
Cubes always involve multiplying a number by itself three times, so if the number is negative the cube will always be negative
Ans squaring results in positive
[tex]f(-x) = -x^3 + 5x -x[/tex] --- eqn 1
[tex]-f(x) = -(x^3 + 5x^2 + x)\\\\-f(x) = -x^3 - 5x^2 - x[/tex] ---- eqn 2
Comparing eqn 1 and eqn 2,
[tex]f(-x) \neq -f(x)[/tex]
Therefore not an odd function
Option 2
[tex]f(x) = \sqrt{x}[/tex]
[tex]f(-x) = \sqrt{-x}[/tex]
[tex]-f(x) = - \sqrt{x}[/tex]
Therefore,
[tex]f(-x) \neq -f(x)[/tex]
Therefore not an odd function
Option 3
[tex]f(x) = x^2 + x\\\\f(-x) = (-x)^2 + (-x)\\\\f(-x) = x^2 - x[/tex]
[tex]-f(x) = -(x^2 + x) = -x^2 - x[/tex]
[tex]f(-x) \neq -f(x)[/tex]
Therefore not an odd function
Option 4
[tex]f(x) = -x\\\\f(-x) = -(-x) = x[/tex]
[tex]-f(x) = -(-x) = x[/tex]
[tex]f(-x) = -f(x)[/tex]
Thus option 4 is correct and it is an odd function

A television is identified by the diagonal measurement of the of screen. A television has a 36 inch screen whose height is 22 inches.what is the length of the television screen
Answer:
28.5 inches.
Step-by-step explanation:
Given: Measurement of diagonal= 36 inch.
Height= 22 inches
Picture attached to show the measurement.
As the screen of televison is measured by diagonal of screen.
∴ Hypotenous= diagonal of screen, which is 36 inches.
Now, using pythagorean theoram to find length of television screen.
[tex]hypotenous^{2} = opposite^{2}+adjacent^{2}[/tex]
∴ [tex]36^{2} = 22^{2} + adjacent^{2}[/tex]
Here adjacent is the length of television.
⇒[tex]1296= 484+ length^{2}[/tex]
Subtracting both side by 484.
⇒[tex]length^{2} = 812[/tex]
Taking square root on both side
remember: [tex]\sqrt{a^{2} } = a[/tex]
∴ [tex]length= \sqrt{812}= 28.495 \approx 28.5[/tex]
Hence, length of televison screen is 28.5 inches.
The width of a television screen can be calculated using the Pythagorean theorem. Given a diagonal of 36 inches and height of 22 inches, the approximate length of the screen is 30 inches.
Explanation:To solve this problem, we will use the Pythagorean theorem which states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This principle can be written as a^2 + b^2 = c^2 where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides.
In the case of a television screen, the diagonal (from one corner to the opposite corner) is the hypotenuse. Given the height of the TV screen as 22 inches (one of the sides of the right triangle), and the diagonal as 36 inches (the hypotenuse), the length (the other side of the right triangle) can be found using the formula.
Let's rearrange the formula to solve for the length (b): b = sqrt(c^2 - a^2). Substitute the given measurements into the formula: length = sqrt(36^2 - 22^2), or approximately 30 inches.

Kurt says factors and multiples are
related. Use the equation 8 X 5 = 40
to label each number as a/
factor or a multiple..
Step-by-step Explanation:
Before heading towards the solution, you need to make sure how multiple and factors are related to each other.
The multiple of a number could be obtained by multiply it with another number.
For example, the first five multiples of 12 are 12, 24, 36, 48 and 60
1 X 12 = 122 X 12 = 243 X 12 = 364 X 12 = 485 X 12 = 60Factors are the numbers that are multiplied to get a given number.
For example,
1 X 12 = 122 X 12 = 243 X 12 = 36The factors of 12 are 1, 2, 3, 4, 6 and 12.
As division and multiplication can be used to find factors and multiples.
For example a whole number is a multiple of its factors.
Let w = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} be the set of even wholes numbers from 2 to 20.
As 2 is a factor of 20 because 20 ÷ 2 = 4
20 is a multiple of 2 because 2 X 10 = 20
So, in the same way, the equation 8 X 5 = 40 can be used to determine how factors and multiples are related.
Let the equation be
8 X 5 = 40
8 is a factor of 40 because 8 X 5 = 40
40 is a multiple of 8 because 40 ÷ 5 = 8
So, this is how factors and multiples are related to each other.

Now, check with the given points B(2,-3) and B([tex]3\frac{1}{3}[/tex] , -2)
1) B(2,-3)
y = [tex]\frac{-3}{2}[/tex] x
⇒(-3) = [tex]\frac{-3}{2}[/tex] × 2

What is the value of p if the line that passes through (2,-4) and (p,8) has a slope of 1/2?
Answer:
Step-by-step explanation:
(2,-4)....x1= 2 and y1 = -4
(p,8).....x2 = p and y2 = 8
slope(m) = 1/2
now use the slope formula (y2 - y1) / (x2 - x1) and sub in what we know...
slope(m) = (y2 - y1) / (x2- x1)
1 / 2 = (8 - (-4) / (p - 2)
1 / 2 = (8 + 4) / (p - 2)
1/2 = 12 / (p - 2) .....now multiply both sides by (p - 2)
1/2(p - 2) = 12
1/2p - 1 = 12
1/2p = 12 + 1
1/2p = 13
p = 13 / (1/2)
p = 13 * 2/1
p = 26
so the value of p is 26

First, we should recall that the function can be rewritten as:
f(x) = 2x/(x2 - 1) = 2x/[(x - 1)(x + 1)]
Now we can calculate the derivatives. For the first derivative f'(x), we use the quotient rule:
f'(x) = [(x2 - 1)(2) - (2x)(2x)]/(x2 - 1)2
For the second derivative f''(x), we differentiate f'(x) again:
f''(x) = Derivative of f'(x) with respect to x
The third derivative f'''(x) is then the derivative of f''(x). Calculations for the second and third derivatives can be a bit complex and lengthy, and it is necessary to apply the quotient rule and product rule carefully.
Through this process, we will arrive at the third derivative, f'''(x), which is what the question asks for.
