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

Matt sold 3 small boxes of oranges and 14 large boxes of oranges for a total of $203. Ming sold 11 small boxes of oranges and 11 large boxes of oranges for a total of $220. Find the cost each of one small box of oranges and one large box of oranges
Answers
Answer: One small box of oranges costs $7 and one large box of oranges costs $13.
Step-by-step explanation:
Let be "s" the cost in dollars of one small box of oranges and "l" the cost in dollars of one small box of oranges.
Based on the data given in the exercise, you can set up the following System of equations:
[tex]\left \{ {{3s+14l=203} \atop {11s+11l=220}} \right.[/tex]
Use the Elimination Method to solve it:
- Multiply the first equation by 11 and the second one by -3.
- Add the equations.
- Solve for "l".
Then:
[tex]\left \{ {{33s+154l=2233} \atop {-33s-33l=-660}} \right.\\...............................\\\\121l=1573\\\\l=13[/tex]
- Substitute the value of "l" into any original equation and solve for "s":
[tex]3s+14(13)=203\\\\3s=203-182\\\\s=\frac{21}{3}\\\\s=7[/tex]

When x increases by 1, y increases by 3/2 = 1.5Step-by-step explanation:
If x and y are proporttional then

From the table we have x = 2 and y = 3.
Substitute:
[tex]3=2a[/tex] divide both sides by 2
[tex]\dfrac{3}{2}=\dfrac{2a}{2}\\\\\dfrac{3}{2}=a\to a=\dfrac{3}{2}[/tex]
Therefore we have:
[tex]y=\dfrac{3}{2}x[/tex]
We increase x by 1:
[tex]y_1=\dfrac{3}{2}(x+1)[/tex] use the distributive property
[tex]y_1=\underbrace{\dfrac{3}{2}x}_{y}+\dfrac{3}{2}\Rightarrow y_1=y+\dfrac{3}{2}[/tex]

Answer:

Step-by-step explanation:
Given: Value of object in 1997 is $5000
Value of object in 2012 is $4500.
Number of years (2012-1997)= 15 years
∵We know that there is growth in value of object over multiple years.
∴Compound annual growth rate (CAGR)= [tex][(\frac{end\ value}{initial\ value} )^{\frac{1}{n} } ] -1[/tex]
Remember, n = number of years
∴ Growth rate= [tex][(\frac{9500}{5000} )^{\frac{1}{15} } ]-1[/tex]
⇒Growth rate= [tex][(1.9)^{\frac{1}{15} } -1][/tex]
⇒Growth rate= [tex](1.9)^{0.0667} -1= 1.0437-1[/tex]
⇒ Growth rate= 0.0437
Now, finding percentage of growth rate
∴ [tex]0.0437\times 100= 4.37\%[/tex]
∴ Annual growth percent over the period of time is 4.37%

What is the domain of the rational function, f of x equals quantity x minus 5 over quantity 2 times x minus 3
Answers
The domain of the function f(x) = (x - 5) / (2x - 3) is all real numbers except for x = 3/2 because this value would cause the denominator of the function to be zero, which is undefined.
Explanation:The domain of a function refers to all possible values that can be inputted into the function, or 'x' values. For a rational function, such as f(x) = (x - 5) / (2x - 3), it is important to note that the function is undefined for values of x that would make the denominator equal zero. Because functions cannot have a denominator of zero, these values should be excluded from the domain.
To find these values, you would set the denominator equal to zero and solve. Thus, 2x - 3 = 0. Solving this, x = 3/2. Therefore, all real numbers except for x=3/2 are in the domain for this rational function.

2) [tex]10\frac{3}{4}-6\frac{4}{4}=3\frac{3}{4}[/tex]
Step-by-step explanation:
You can convert he mixed numbers to improper fractions:
1. Multiply the whole number part by the denominator of the fraction.
2. Add the product obtained to the numerator.
3. The denominator does not change.
Then:
[tex]9\frac{1}{6}=\frac{54+1}{6}=\frac{55}{6}\\\\8\frac{5}{6}=\frac{48+5}{6}=\frac{53}{6}\\\\10\frac{3}{4}=\frac{40+3}{4}=\frac{43}{4}\\\\6\frac{4}{4}=\frac{24+4}{4}=\frac{28}{4}[/tex]
Observe that, in each subtraction, the denominators are equal, then you can rewrite the denominator and subtract the numerators:
[tex]1)\ \frac{55}{6}-\frac{53}{6}=\frac{55-53}{6}= \frac{2}{6}=\frac{1}{3} \\\\2)\ \frac{43}{4}-\frac{28}{4}=\frac{43-28}{4}= \frac{15}{4}[/tex]
Divide 15 by 4. The quotient will be 3 and the remainder 3.
Then:

Find the inverse
step 1
Let
y=f(x)
[tex]y=4x+12[/tex]
step 2
Exchange the variables (x for y and y for x)
[tex]x=4y+12[/tex]
step 3
Isolate the variable y
we have
[tex]x=4y+12[/tex]
Subtract 12 both sides
[tex]x-12=4y[/tex]
Divide by 4 both sides
[tex]y=\frac{x-12}{4}[/tex]
simplify
[tex]y=\frac{1}{4}x-3[/tex]
step 4
Let
[tex]f^{-1}(x)=y[/tex]
[tex]f^{-1}(x)=\frac{1}{4}x-3[/tex]
we have that

[tex]g(x)=\frac{1}{4}x-3[/tex]
what is the function, domain and range of {(1,1) (2,2) (3,5) (4,10) (5,15)}?
Answers
The domain is all the x values : 1,2,3,4,5
The range is all the y values: 1,2,5,10,15
Step-by-step explanation: To determine whether the relation shown here is a function, it's important to understand that a function is a relation in which each x-term corresponds to exactly one y-term.
Each of the x-terms shown here 1, 2, 3, 4, and 5 appears only once so each x-term corresponds to only one y-term. So yes, this relation is a function.
The domain of a relation is the set of all the x-terms of the relation. So here, the domain will be the set of all the x-terms or {1, 2, 3, 4, 5}.
The range of a relation is the set of all the y-terms of the relation. SO here, the range will be the set of all the y-terms or {1, 2, 5, 10, 15}.

A 5 pairs of jeans and 2 sweatshirts costs $233, while 3 pairs of jeans and 4 sweatshirts costs $193. Find the cost of one sweatshirt.
Answers
The cost of one sweatshirt is $19.
Step-by-step explanation:
Let,
Cost of one pair of jeans = x
Cost of one sweatshirt = y
According to given statement;
5x+2y=233 Eqn 1
3x+4y=193 Eqn 2
Multiplying Eqn 1 by 2
[tex]2(5x+2y=233)\\10x+4y=466\ \ \ Eqn\ 3[/tex]
Subtracting Eqn 2 from Eqn 3
[tex](10x+4y)-(3x+4y)=466-193\\10x+4y-3x-4y=273\\7x=273[/tex]
Dividing both sides by 7
[tex]\frac{7x}{7}=\frac{273}{7}\\x=39[/tex]
Putting x=39 in Eqn 2
[tex]3(39)+4y=193\\117+4y=193\\4y=193-117\\4y=76[/tex]
Dividing both sides by 4
[tex]\frac{4y}{4}=\frac{76}{4}\\y=19[/tex]
The cost of one sweatshirt is $19.

(is there a way to solve this without having to go through all the options)
Answers
There are 59 eggs in the basket
Step-by-step explanation:
There are between 50 & 60 eggs in a basket
When Roza counts by 3's there are 2 leftoverWhen she counts by 5's there are 4 leftoverWe need to find how many eggs in the basket
∵ When Roza counts by 3's there are 2 leftover
∵ When she counts by 5's there are 4 leftover
- That means the number of eggs when divided by 3 give
remainder 2 and when divided by 5 give remainder 4
- To find the number look for the numbers that divisible by 5 and
add 4 to them and then check the remainder when they divided
by 3
∵ Between 50 and 60 there is only one number divisible by 5
is 55 (not including 50 or 60)
∵ 55 + 4 = 59
∴ 59 gives remainder 4 when divided by 5
Let us check them with 3
∵ 59 - 2 = 57
∵ 57 is divisible by 3 ⇒ (57 ÷ 3 = 19)
∴ 59 when divide by 3 gives remainder 2
∴ 59 gives remainder 4 when divided by 5 and remainder 2 when
divided by 3
∴ The number of eggs in the basket is 59
There are 59 eggs in the basket

Make a conjecture about the diagram below. Do you think you can conclude that △JKL ≅ △XYZ? Explain your reasoning.
Answers
Answer:
△JKL ≅ △XYZ by HL congruency for right triangles
Step-by-step explanation:
If only given two sides and an uncontained angle, the triangles may not necessarily be congruent. However, since the given angle is a right angle, they are congruent.
When given that the hypotenuse and any "leg" of the right triangles are equal, the triangles are congruent.
Since one angle is 90°, the other two angles must be acute. This is unlike the ambiguous case when given an uncontained acute angle, where two possible triangles can be made by making another angle obtuse.
Imagine an isosceles triangle cut in half at the altitude, creating two right triangles (JKL and XYZ). They have the same angle measures. Each with a right angle, the angle that had an equal measure in the isosceles, and the unequal angle bisected. For the triangles' sides, the isosceles base was bisected by the altitude, and they have the same altitude.
