Answer:

4 copies

Step-by-step explanation:

After yesterday's sales, 1/3 of the original supply remained. After today's sales, 1/5 of that value remain. So the remaining number is ...

60·(1/3)(1/5) = 60/15 = 4

The bookstore has 4 copies of the magazine left after selling 2/3 of them on the first day and 4/5 of the remaining on the second day.

The bookstore originally has 60 copies of a magazine. On the first day, it sold 2/3 of them, which equals to 60*(2/3) = 40 copies. So, there are 60 - 40 = 20 copies left. On the second day, it sold 4/5 of what remained, that is, 20*(4/5) = 16 copies. After this, the remaining copies are 20 - 16 = 4 copies.

option B) f(x)=x^3-6x^2+11x-6

Step-by-step explanation:

Zeros means the point at which a given function becomes zero for the value of input.

In given case, zeros of f(x) is required at points 1,2 and 3.

Graphically the point on x-axis where the function line intersects the x-axis is the zero of the function i.e. the function value is 0,

hence

f(x)=0 when x=1

x-1=0

f(x)=(x-1)

f(x)=0 when x=2

x-2=0

f(x)=(x-2)

f(x)=0 when x=3

x-3=0

f(x)=(x-3)

Thus f(x)=(x-1)(x-2)(x-3)

Writing the above polynomial in standard form:

f(x)=x^3-6x^2+11x-6 !

The formula for the absolute value function that has its vertex at point (0,6) and passes through the point (-1,-2) is y = -1/8|x| + 6.

To find the formula of an absolute value function, we need to use the formula |x - h| = a(y - k), where (h, k) is the vertex of the graph. In this case, the vertex is at point (0,6), so h = 0 and k = 6. The other point given is (-1,-2). We can substitute these values into the formula to find the value of 'a'. So, |-1 - 0| = a(-2 - 6) which simplifies to 1 = -8a. Solving this equation gives us a = -1/8. So, the formula for the absolute value function in this case is y = -1/8|x - 0| + 6 or just y = -1/8|x| + 6.

The formula for the absolute value function with a vertex at (0,6) and passing through the point (-1,-2) is y = -8|x| + 6.

The formula for the absolute value function with a vertex at (0,6) and passing through the point (-1,-2) can be determined by considering how the graph of an absolute value function is shifted and stretched. In general, the formula for an absolute value function with a vertex at (h,k) can be written as y = a|x-h| + k. Using the given information, we can substitute the values h=0 and k=6 into the formula, and use the point (-1,-2) to solve for the value of a:

-2 = a|(-1)-0| + 6

-2 = a|-1| + 6

-2 = a + 6

a = -8

Therefore, the formula for the absolute value function is y = -8|x-0| + 6, which simplifies to y = -8|x| + 6.

Final answer:

The product of (3 the square root of 8)(4 the square root of 3) is simplified to 24√6, which is the final simplified form as the radical cannot be simplified further.

Explanation:

The product of (3 the square root of 8) and (4 the square root of 3) involves using properties of radicals and multiplication. First, simplify the square root of 8 to 2√2 because 8 is 4 times 2, and 4 is a perfect square whose square root is 2. Now the expression becomes (3∙2√2)∙(4√3). We then multiply the coefficients (3∙2) and (4), which is 24, and the radicals √2 and √3 which is √6. The final product is 24√6, which cannot be simplified further as 6 is not a perfect square.

Answer:

A = $7,350.00

Step-by-step explanation:

Equation:

A = P(1 + rt)

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year.

Putting time into years for simplicity,

30 months / 12 months/year = 2.5 years.

Solving our equation:

A = 6000(1 + (0.09 × 2.5)) = 7350

A = $7,350.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 9% per year for 2.5 years (30 months) is $7,350.00.

* Therefor, the answer is $7,350.00.

* Hopefully this helps:) Mark me the brainliest:)!!!

To find Dominick's monthly installment payments for a $6,000 loan at 9% simple interest over 30 months, you first calculate the total interest ($1,350), add it to the principal to get the total amount owed ($7,350), and then divide by the number of months (30) to find the monthly payment, which is approximately $245.

Calculating Monthly Installment Payments

Dominick borrowed $6,000 from a credit union at 9% simple interest for 30 months. To calculate the total amount of interest, we'll use the formula for simple interest, which is Interest (I) = Principal (P) × Rate (R) × Time (T). For this loan, the principal P is $6,000, the annual interest rate R is 9% (or 0.09 when expressed as a decimal), and the time T is 30 months (or 2.5 years). Plugging these values into the formula gives us:

I = $6,000 × 0.09 × 2.5 = $1,350

The total amount owed, including interest, is $6,000 + $1,350 = $7,350. To determine the monthly installment payments, we divide this total amount by the number of months over which the loan will be repaid, which is also 30 months.

Monthly Installment Payments = Total Amount / Number of Months

Monthly Installment Payments = $7,350 / 30 ≈ $245

So, Dominick's monthly installment payment is approximately $245 to the nearest whole cent.

[tex]f^{-1}(x)=\frac{x-2}{4}[/tex]

To find the inverse of a function, we need to rewrite the variable "x" with "y" and the variable "y" with "x", and then, isolate "y".

We are given the function:

[tex]f(x)=4x+2[/tex]

Write "f(x)" is equal to write "y", so:

[tex]y=4x+2[/tex]

Now, finding the inverse, we have:

[tex]y=4x+2\\x=4y+2\\x-2=4y\\y=\frac{x-2}{4}[/tex]

Hence, we have that the answer is the first option,

[tex]f^{-1}(x)=\frac{x-2}{4}[/tex]

ANSWER

[tex]{f}^{ - 1} (x) = \frac{x - 2}{4} [/tex]

EXPLANATION

The given function is

f(x)=4x+2

To find the inverse, we let

y=4x+2

Then, interchange x and y.

x=4y+2

Solve for y,

x-2=4y.

Divide both sides by 4

[tex]y = \frac{x - 2}{4} [/tex]

Hence, the inverse is:

[tex] {f}^{ - 1} (x) = \frac{x - 2}{4} [/tex]

Answer:

x = - 7, x = 0 and x = 4

Step-by-step explanation:

Factor the polynomial and solve for x

Given

x³ + 3x² - 28x = 0 ← factor out x from each term

x(x² + 3x - 28) = 0 ← factor the quadratic

x(x + 7)(x - 4) = 0

Equate each factor to zero and solve for x

x = 0

x + 7 = 0 ⇒ x = - 7

x - 4 = 0 ⇒ x = 4

For this case we have that by definition, the area of a triangle is given by:

[tex]A = \frac {1} {2} b * h[/tex]

Where:

b: It's the base

h: It's the height

Substituting the values, according to the given data:

[tex]225 = \frac {1} {2} (15) * h\\225 = 7.5h[/tex]

Dividing between 7.5 on both sides of the equation:

[tex]h = \frac {225} {7.5}\\h = 30[/tex]

Thus, the height of the triangle is 30ft

Answer:

30ft

Answer: 30 feet.

Step-by-step explanation:

The formula used to calculate the area of a triangle is:

[tex]A=\frac{bh}{2}[/tex]

Where "b" is the base and "h" is the height.

In this case you know that the area of this triangle is 225 ft² and its base is 15 ft. Then, you can substitute these values into the formula [tex]A=\frac{bh}{2}[/tex] and solve for the height "h":

[tex]225ft^2=\frac{(15ft)h}{2}[/tex]

[tex](2)(225ft^2)=(15ft)h[/tex]

[tex]h=\frac{(2)(225ft^2)}{15ft}[/tex]

The third side of the triangle = 14.6 ÷ 2 = 7.8

We now have a right triangle with legs x and 7.8 with hypotenuse 8.8

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 7.8² = 8.8²

x² + 60.84 = 77.44 ( subtract 60.84 from both sides )

x² = 16.6 ( take the square root of both sides )

x = [tex]\sqrt{16.6}[/tex] ≈ 4.1 ( nearest tenth )

Answer:

4.1

Step-by-step explanation:

⇒The missing side of the triangle is 7.8 cm

We use Pythagoras theorem to solve x

a² = b² + c²

In this case, a = 7.8 cm and c = 8.8 cm

→ 7.8² = x² + 8.8²

( Rearrange )

→ x² = 8.8² - 7.8²

( Simplify )

→ x² = 77.44 - 60.84

( Simplify )

→ x² = 16.6

( Square root )

→ x = 4.074309757
