Final answer:

Being a storehouse of value means the item retains its worth over time, allowing it to be saved, stored, and reliably used later as a medium of exchange, like money or other assets with lasting value.

Explanation:

To be a storehouse of value means that the item, such as money, can retain its worth over some time. Unlike goods that may deteriorate, go out of style, or otherwise lose value, a storehouse of value allows individuals to save and store their wealth, retrieving it later with confidence that it will still be valuable.

Money is a common store of value since you do not need to spend it right away and can trust that even with the potential erosion of value due to inflation, it will remain a valid medium for future transactions.

Goods such as houses, artworks, or financial assets are also considered stores of value, but money is distinguished by its liquidity—being readily exchangeable for other goods or services. Although not perfect due to inflation, money's role as a medium of exchange in financial markets and aggregate expenditure makes it a convenient choice for storing value, especially when compared to the barter system.

In conclusion, option D - Any item that maintains its worth over time, accurately describes a storehouse of value.

The terms 'solution,' 'root,' 'x-intercept,' and 'zero' are related in mathematics, but they are not always the same.

The statement in the question is false. Though the terms 'solution,' 'root,' 'x-intercept,' and 'zero' are related in mathematics, they are not always the same.

In quadratic equations, for example, the 'solution' refers to the values of x that make the equation equal to zero, while 'root' refers to the values of x that satisfy the equation. 'X-intercept' refers to the points on the graph where the equation intersects the x-axis, while 'zero' refers to the x-values for which the equation equals zero.

It's <2 and <5.

Answer:

[tex]y^4+1+\dfrac{1}{y^4}[/tex]

Step-by-step explanation:

Consider expression

[tex]y^7-\dfrac{1}{y^5}[/tex]

Rewrite it:

[tex]\dfrac{y^7\cdot y^5-1}{y^5}=\dfrac{y^{12}-1}{y^5}[/tex]

Consider the numerator:

[tex]y^{12}-1=(y^4)^3-1^3[/tex]

Use formula:

[tex]a^3-b^3=(a-b)(a^2+ab+b^2)[/tex]

So,

[tex](y^4)^3-1^3=(y^4-1)((y^4)^2+y^4\cdot 1+1^2)=(y^4-1)(y^8+y^4+1)[/tex]

Now,

[tex]\dfrac{y^7\cdot y^5-1}{y^5}=\dfrac{(y^4-1)(y^8+y^4+1)}{y^5}=\dfrac{y^4-1}{y}\cdot \left(y^4+1+\dfrac{1}{y^4}\right)[/tex]

Hence,

Answer:

[tex]5x + 2\frac{1}{2} = 15[/tex]  and [tex]\frac{15 - 2\frac{1}{2} }{5}[/tex]

Step-by-step explanation:

Assume the length of each piece of wood is x feet.

We can say that the length of uncut board = (number of pieces × length of each piece) + length of leftover board, or [tex]15 = 5x + 2\frac{1}{2}[/tex].

Apply the Symmetric Property of Equality:

[tex]5x + 2\frac{1}{2} = 15[/tex]

Subtract [tex]2\frac{1}{2}[/tex] from both sides of the equation:

[tex]5x = 15 - 2\frac{1}{2}[/tex]

Divide both sides by 5: (See image)

Cancel out the common terms from the numerator and denominator:

[tex]x = \frac{5}{2}[/tex]

[tex]= 2\frac{1}{2}[/tex]

Answer:

The equation of M is [tex]y=-(x+3)^2+6[/tex]

Step-by-step explanation:

we have that

The translation of M to N is

(-1,2) ----> (4,2)

The rule of the translation M to N is

(-1,2) ----> (x+a,y+b)

(-1,2) ----> (-1+a,2+b)

so

[tex]-1+a=4[/tex] ----> [tex]a=4+1=5[/tex]

[tex]2+b=2[/tex] ----> [tex]b=0[/tex]

The rule of the translation M to N is

(x,y) ----> (x+5,y)

The translation is 5 units right

I can say that the rule of the translation  N to M is

(x,y) ----> (x-5,y)

we have the equation of N

[tex]y=-(x-2)^2+6[/tex]

Is a quadratic equation open downward

The vertex is (2,6)

Find the vertex of M

Applying the rule of the translation N to M to the vertex

(2,6) ----> (2-5,6)

(2,6) ----> (-3,6)

therefore

The equation of M is

[tex]y=-(x+3)^2+6[/tex]

Answer:

[tex](8^{\frac{2}{3} } )^{4} = 256[/tex]

Step-by-step explanation:

Given

[tex](8^{\frac{2}{3} } )^{4}[/tex]

Required

Simplify

To simplify this, we apply law of indices but first we start by solving the expression in bracket.

8 =2 * 2 * 2

8 = 2³

So, we substitute 2³ for 8

[tex](8^{\frac{2}{3} } )^{4}[/tex] becomes

[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex]

From law of indices

[tex]a^{n} = (a^{m})^{\frac{n}{m} }[/tex] ==> [tex](a^{m})^{\frac{n}{m} } = a^{n}[/tex]

So, [tex](2^{3})^{\frac{2}{3} } = 2^{2}[/tex]

At this point we have

[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex] = [tex](2^{2})^{4}[/tex]

Also, from law of indices

[tex](a^{m})^{n} = a^{m.n}[/tex]

So,

[tex]((2^{3})^{\frac{2}{3} } )^{4}[/tex] = [tex](2^{2})^{4}[/tex]

[tex](2^{2})^{4} = 2^{2*4}[/tex]

[tex](2^{2})^{4} = 2^{8}[/tex]

[tex](2^{2})^{4} = 256[/tex]

Hence,

[tex](8^{\frac{2}{3} } )^{4} = 256[/tex]

Answer:

The answers are 10/24 and 9/24.

Step-by-step explanation:

Given:

Tim has 5/12 of a jar of blackberry jam and 3/8  of a jar of strawberry jam.

Now, to write using a common denominator.​

So, we get the multiples of denominator of the fractions to get common denominator:

12 - 12, 24, 36.

8  -  8, 16, 24.

Here we see that 24 is the common denominator.

Now, we multiply the numerator and denominator with the same number to get the common denominator of the fractions:

⇒  [tex]\frac{5}{12}=\frac{5\times 2}{12\times 2} =\frac{10}{24}[/tex]

⇒  [tex]\frac{3}{8}=\frac{3\times 3}{8\times 3} =\frac{9}{24}[/tex]

Answer:

{3, 6}

Step-by-step explanation:

f(x) is the same thing as y. f(x) or y are the values that are shown in the range.

The domain represents all possible values of x. Data must be in an (x, y) form, where any value of "y" would need a partner, "x".

Substitute all of the possible x-values into the formula to find all possible y-values (the range).

f(x) = x² - 2x + 3

f(-1) = (-1)² - 2(-1) + 3

f(-1) = 1 + 2 + 3

f(-1) = 6

f(x) = x² - 2x + 3

f(0) = (0)² - 2(0) + 3

f(0) = 0 - 0 + 3

f(0) = 3

f(x) = x² - 2x + 3

f(2) = (2)² - 2(2) + 3

f(2) = 4 - 4 + 3

f(2) = 3    Do not write repeated numbers

The possible y-values are 3 and 6.

Writ the range in set notation in the brackets {}. Order the numbers from least to greatest.

Range is {3, 6}.

The range of a function with a specified domain is equal to {3, 6}.

Range of the function:

The function is f(x) = x² - 2x + 3. Given the domain {-1, 0, 2}, we can find the corresponding range by evaluating the function at each point in the domain:

For x = -1: f(-1) = (-1)² - 2(-1) + 3 = 6.

For x = 0: f(0) = 0² - 2(0) + 3 = 3.

For x = 2: f(2) = 2² - 2(2) + 3 = 3.

The range of this function for the given domain is {3, 6}.

Answer:

1) Two terms

2) Three factors

Step-by-step explanation:

We are given the following expression:

abc + def

We have to compete the given statement with the help of given expression.

abc - 3 factors: a, b and c

def - 3 factors: d, e and f

The expression abc + def consists of two algebraic terms, each with three factors.

The expression abc + def consists of two terms, and each term contains three factors. To elaborate, a term in algebra is a single part of an expression separated by plus or minus signs. The given expression has two distinct groupings separated by a plus sign: 'abc' and 'def'. Each of these groupings is considered a term. Moreover, within each term, there are three variables multiplied together, hence each term contains three factors. Understanding this fundamental concept of terms and factors is crucial for manipulating algebraic expressions, factoring, and solving equations more efficiently.

Jennifer feeds total fishes is 280

Step-by-step explanation:

Tony feeds total fishes is 56

Jennifer feeds 5 times as many fish as Tony feeds

Jennifer [tex]=[/tex] 5 × Tony

              [tex]=[/tex]   5 × 56

              [tex]=[/tex]   280

Jennifer feeds total fishes is 280

Final answer:

Jennifer feeds 280 fish.

Explanation:

To find out how many fish Jennifer feeds, we need to perform a simple multiplication. Since Jennifer feeds 5 times as many fish as Tony, and Tony feeds 56 fish, we can write the following equation to represent the situation:

f = 5 × 56

We then multiply 56 by 5:

f = 280

So, Jennifer feeds 280 fish.

Answer:

4x^2+20x+24

Step-by-step explanation:

(4x+8)(x+3)=4x^2+8x+12x+24=4x^2+20x+24

The value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3

We have two functions -

f(x) = 4x + 8

g(x) = x + 3

We have to determine f(x)*g(x).

A function in mathematics is an expression with a independent variable (x) in it. The variable is called independent because it is not dependent on any value to get its value. Function also has a dependent variable (y) whose value depend on x. Ex -

y = f(x) = ax + d

According to the question, we have -

f(x) = 4x + 8

g(x) = x + 3

Therefore -

f(x) * g(x) = (4x + 8)(x + 3) = 4x(x + 3) + 8(x + 3) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3

Hence, the value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3

Answer:

D

Step-by-step explanation:

In probability,

a probability of 0 means that it is IMPOSSIBLE, sure that this event WILL NOT occur, ever. So, probability of anything less than 0 is not possible.

On the other hand, probability of 1 means that it is CERTAIN to happen. So, probabilty of anything greater than 1 can't happen.

So we can say:

0 <= Probability of an Event happening <= 1

Option A is 1/2, which is in the middle, so this is OKAY.

Option B is 10%, which is certainly close to 0 and between 0 and 1, so this is OKAY.

Option C is 0.7, which is close to 1 and greater than 0, so in between 0 and 1, certainly. So this is OKAY.

Option D is 3/2 which is 1.5, so this is GREATER THAN 1, so it can't ever be possible.

Option D is the correct choice.

[tex]10.50p+15\leq 65[/tex]

[tex]p\leq \frac{100}{21}[/tex]

Step-by-step explanation:

Let p represent pounds of Pumpkin Spice coffee.

We have been given that Lydia is at a coffee shop and knows  she can spend no more than $65  before tax. She sees this price list in  the coffee shop.

Item                                               Price per pound

Dark Roast Coffee                                 $7.50

Pumpkin Spice Coffee                         $10.50

Breakfast Tea                                       $23.50

Lydia wants to buy  2 pounds of  Dark Roast coffee, so the cost of 2 pounds of Dark Roast coffee would be [tex]\$7.50\times 2=\$15[/tex].

We are told that cost of each pound of Pumpkin Spice coffee is $10.50, so cost of 'p' pounds of Pumpkin Spice coffee would be [tex]10.50p[/tex].

Since Lydia can spend no more than $65  before tax, so the cost of 2 pounds of  Dark Roast coffee and 'p' pounds of Pumpkin Spice coffee must be less than or equal to 65.

We can represent this information in an inequality as:

[tex]10.50p+15\leq 65[/tex]

Therefore, our required inequality would be [tex]10.50p+15\leq 65[/tex].

[tex]10.50p+15-15\leq 65-15[/tex]

[tex]10.50p\leq 50[/tex]

Divide both sides by 10.50:

[tex]\frac{10.50p}{10.50}\leq \frac{50}{10.50}[/tex]

[tex]p\leq \frac{50*2}{10.50*2}[/tex]

[tex]p\leq \frac{100}{21}[/tex]

[tex]p\leq 4.76190[/tex]

Therefore, Lydia can buy less than or equal to [tex]\frac{100}{21}[/tex] pounds of Pumpkin Spice coffee.
