Step-by-step explanation:
To solve the log equation, the appropriate system of equations is y₁ = log₀.₅ x and y₂ = log₃(2+x) as these correspond to the format of the original log equation, where we can equate the two and solve for x.
Explanation:To solve the equation log₀.₅ₓ = log₃ (2+x), we can rewrite it in a form that helps us find a system of equations.
First, apply the change of base formula for logarithms:
log ab/ log ac = log cb.
Using this formula, we can rewrite the given equation as:
log 0.5x / log₀.₅ 10 = log₃(2+x) / log₃10
Now, we can create a system of equations with the following relationships:
y₁ = log₀.₅ x / log₀.₅10
y₂ = log₃(2+x) / log₃10
Therefore, the correct choice is:
y₁ = logₓ/log₀.₅ , y₂= log(2+x)/ log 3

There are 216 one-inch cubes stacked in such a way as to create a larger cube. How many one-inch cubes are on a single edge of the larger cube?
Final answer:
To find out how many one-inch cubes are on a single edge of the larger cube formed by stacking 216 cubes, take the cube root of 216, which is 6. Therefore, each edge has 6 one-inch cubes.
Explanation:
If there are 216 one-inch cubes stacked to form a larger cube, we need to determine how many cubes are along each edge of this larger cube. The volume of a cube is calculated as length × width × height, and since all sides of a cube are equal, we can say that the length, width, and height are all the same. Therefore, to find the length of one side, we take the cube root of the volume. The cube root of 216 is 6, meaning each edge of the larger cube is composed of 6 one-inch cubes.

Question:
A. 1) Only some squares are rectangles. 2) Rectangles have 4 right angles. 3) Therefore, only some squares have 4 right angles.
B. 1) Only some squares are rectangles. 2) Rectangles have 4 sides that are the same length. 3) Therefore, only some squares have 4 sides that are the same length.
C. 1) All squares are rectangles. 2) Rectangles have 4 sides that are the same length. 3) Therefore, all squares have 4 sides that are the same length.
D. 1) All squares are rectangles. 2) Rectangles have 4 right angles. 3)Therefore, all squares have 4 right angles.
Answer:
All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.
Step-by-step explanation:
Let's go by process of elimination. Starting with A.
A. 1) Only some squares are rectangles. 2) Rectangles have 4 right angles. 3) Therefore, only some squares have 4 right angles.
You can already tell that it's incorrect just looking at sentence 1). All squares are rectangles because a rectangle is:
1. Quadrilateral.
2. Two pairs of parallel sides.
3. Four right angles.
Sentence 2) is correct because Rectangles have 4 right angles. But sentence 3) is incorrect because all squares have 4 right angles.
Down to B.
B. 1) Only some squares are rectangles. 2) Rectangles have 4 sides that are the same length. 3) Therefore, only some squares have 4 sides that are the same length.
Same thing in the first sentence as A . Sentence 1) is incorrect since all squares are rectangles. Sentence 2) is also incorrect because Rectangles do not have the same lengths on all four sides. Only two sides are the same in length. The sides that are the same are the two sides across from each other. Sentence 3) is also incorrect since all squares have 4 sides that are the same length.
Moving down again to C.
C. 1) All squares are rectangles. 2) Rectangles have 4 sides that are the same length. 3) Therefore, all squares have 4 sides that are the same length.
Sentence 1) is correct. All squares are rectangles. Sentence 2) is incorrect because not all sides are the same length. Sentence 3) is correct because all squares have 4 sides that are the same length.
Down to D. (The correct answer.)
D. 1) All squares are rectangles. 2) Rectangles have 4 right angles. 3)Therefore, all squares have 4 right angles.
Sentence 1) is correct because all squares are in fact, rectangles. here is a fact about squares:
"A square is a quadrilateral with all four angles, right angles, and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles."
Sentence 2) is also correct because all rectangles have four right angles. Here are some more facts about rectangles:
"All rectangles are parallelograms, but all parallelograms are not rectangles.
The diagonals of a rectangle divide the rectangle into four triangles.
Every square is a rectangle, but every rectangle is not a square."
Sentence 3) is correct. All squares have 4 right angles. Therefore, Option D. would be your correct answer.
What is the domain of the profit function P=6t+10s?
Answer:A
Step-by-step explanation:
The required profit function is defined for all s and t greater than or equal to zero. Option A is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The profit function P=6t+10s represents the profit made by a company based on the number of units of two products: t units of product 1 and s units of product 2.
In general, the domain of the profit function depends on the specific context of the problem, but in the problem, we have no constraints so the domain of the profit function would be all real values for s and t greater than or equal to zero.
Thus, the required profit function is defined for all s and t greater than or equal to zero. Option A is correct.

Yasemin deposited $1000 into a savings account.
The relationship between the time, t, in years, since the account was first opened, and Yasemin's account
balance, B(t), in dollars, is modeled by the following function.
B(t) = 1000. 20.03
How many years will it take for Yasemin's account balance to reach $1500?
Round your answer, if necessary, to the nearest hundredth.
Answer:
The number of years it will take for Yasemin's account balance to reach $1500 is 13.52 years.
Step-by-step explanation:
Where the model of the relationship between the time, t, in years, since the account was first opened and the and the balance in Yasemin's account is presented as follows;
[tex]B(t) = 1000 \times e^{(0.03 \times t)}[/tex]
To find find out how many years it will take for Yasemin's account balance to reach $1500, we substitute B(t) = $1500 since we are told that after the years his account balance became $1500 as follows;
[tex]\$ 1500 = 1000 \times e^{(0.03 \times t)}[/tex]
We now solve for t
[tex]\$ 1500 = 1000 \times e^{(0.03 \times t)}\\\\\frac{1500 }{1000 } = e^{(0.03 \times t)}\\1.5 = e^{(0.03 \times t)}\\\\ln(1.5) = ln (e^{(0.03 \times t)})\\\\ln(1.5) = (0.03 \times t) \times ln (e)\\\\\therefore ln(1.5) = (0.03 \times t) \\\\t = \frac{ln(1.5)}{0.03 } = 13.52 \ years[/tex]
The number of years it will take for Yasemin's account balance to reach $1500 = 13.52 years.

The domain is all natural numbers and the range is real numbers
Step-by-step explanation:
Step 1: Find the correct answer
Option A is correct because if you plug in the numbers...
[tex]f(0 + 1) = \frac{10}{3}[/tex] → [tex]f(1)=\frac{10}{3}[/tex]
[tex]f(1 + 1) = \frac{6}{5} * \frac{10}{3}[/tex] → [tex]f(2)=4[/tex]
[tex]f(2 + 1) = \frac{6}{5} * \frac{4}{1}[/tex] → [tex]f(3) = \frac{24}{5}[/tex]
[tex]f(3 + 1) = \frac{6}{5} * \frac{24}{5}[/tex] → [tex]f(4) = \frac{144}{25}[/tex]
Also, Option C is correct because if you plug in the numbers...
[tex]f(1) = \frac{10}{3}(\frac{6}{5})^(^1^-^1^)[/tex] → [tex]f(1) = \frac{10}{3} * 1[/tex] → [tex]f(1)=\frac{10}{3}[/tex]
[tex]f(2) = \frac{10}{3}(\frac{6}{5})^(^2^-^1^)[/tex] → [tex]f(2) = \frac{10}{3}*\frac{6}{5}[/tex] → [tex]f(2) = 4[/tex]
[tex]f(3) = \frac{10}{3}(\frac{6}{5})^(^3^-^1^)[/tex] → [tex]f(3) = \frac{10}{3}*\frac{36}{25}[/tex] → [tex]f(3) = \frac{24}{5}[/tex]
[tex]f(4) = \frac{10}{3}(\frac{6}{5})^(^4^-^1^)[/tex] → [tex]f(4) = \frac{10}{3} * \frac{216}{125}[/tex] → [tex]f(4) = \frac{144}{25}[/tex]
The reason why option B is not correct is because when you plug in a number, the output is incorrect. The reason why Option D is not correct is because the domain does not include negative numbers which means that the domain is all natural numbers. The reason why Option E is not correct is because the range is all real numbers and not just natural/positive numbers.

What is the number of ordered pairs (x,y) that are solutions to
4x+5y=2017
where both x and y are positive integers?
Answer:
Step-by-step explanation:
An ordered pair is a pair of coordinates on a graph that satisfy a particular equation.
From our question, the given equation is
4x + 5y = 2017
5y = 2017 - 4x
y = (2017 - 4x) / 5
but (x,y) are positive integers meaning that x and y > 0
when x = 1, y = (2017 - 4) /5
y = 2013/5
=402.6
Hence (x.y) = (1. 402.6) which is not a solution to the equation
when x = 2 , y = (2017 -8) /5
y = 2009/ 5 = 401.8
(x,y) = (2, 401.8) which is not a solution to the equation
when x = 3 , y = (2017 - 12)/ 5
y = 2005/5 = 401
(x, y) = (3, 401) which is a solution to the equation
when x =5 , y = (2017 - 20) / 5
y = 1997/5 = 399.4
(x,y) = (5, 399.4) which is not a solution to the equation
