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.

the like terms are 9x and 7x, if you are told to simplify, you write, "12y+16x"

12y + 9x + 7x

The like terms are 9x and 7x. This is because they both have the x variables attached to the number. This means that you can add only 9x and 7x (not 12y because it isn't a like term) together like normal numbers (except with an x at the end so you would get: 12y + 16x

3\sqrt{8}\cdot4\sqrt{3} \\

12\sqrt{24} \\

12\cdot2\sqrt{6} \\

\boxed{24\sqrt{6}}

[/tex]

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.

9,12,18 is a right triangle and so is 30,72,90

Answer:

Step-by-step explanation:

x+2y=-2

2y = - x -2

y = -1/2 x -1 ... (The first line)   red

y=1/2x-5 ( the second line ) bleus

the solution to the system of equations is (4 ; -3) intersection of two line

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]

[tex]h=30ft[/tex]

Answer:

[tex](x-4)^2+(y-3)^2=2^2[/tex]

Step-by-step explanation:

The given circle has equation; [tex]x^2+y^2-8x-6y+24=0[/tex]

Comparing to the general equation of the circle:  [tex]x^2+y^2+2ax+2by+c=0[/tex]

We have [tex]2a=-8\implies a=-4[/tex] and [tex]2b=-6\implies b=-3[/tex]

The center of this circle is (-a,-b)=(4,3).

The required circle has radius r=2 units.

The equation of a circle, given the center (h,k) and radius r, is given by:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

We substitute the values to obtain [tex](x-4)^2+(y-3)^2=2^2[/tex]

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 !

[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]

Have a nice day!

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:

a. [tex]d=2.0t[/tex]

b. 26 meters

c. picture attached

Step-by-step explanation:

- Since the turtle travels 2.0 meters per minute, it will travel a total distance of [tex]2.0t[/tex] in [tex]t[/tex] minutes. We know that the total distance is [tex]d[/tex], so we can equate both total distances to create our rule:

[tex]d=2.0t[/tex]

- To find the distance of the turtle after 13 minutes we just need to replace [tex]t[/tex] with 13 in our rule:

[tex]d=2.0t[/tex]

[tex]d=2.0(13)[/tex]

[tex]d=26[/tex]

The turtle cover a distance of 26 meters after 13 minutes.

- To graph the function we are going to evaluate our function at two points, and then we are joining those two points with a line (check the attached picture)

We already know that the turtle cover a distance of 26 meters after 13 minutes, since the distance depends on the time our point will have coordinates (time, distance) (13 minutes, 26 meters) (13, 26)

Notice that when time is zero, distance is zero as well, so our second point is (0, 0)

Now we can join the points using a line:

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.

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

Answer:

(x - 4)(x + 1)

Step-by-step explanation:

Given

x² - 3x - 4

To factor the trinomial

Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)

The factors are - 4 and + 1, since

- 4 × 1 = - 4 and - 4 + 1 = - 3, hence

x² - 3x - 4 = (x - 4)(x + 1)

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
