[tex]x = - \frac{2\pi}{3} [/tex]

EXPLANATION

The given function has equation

[tex]y = \tan( \frac{3}{4}x) [/tex]

This can be rewritten as

[tex]y = \frac{ \sin( \frac{3}{4}x ) } { \cos(\frac{3}{4}x )}[/tex]

The asymptote occurs at:

[tex]\cos(\frac{3}{4}x ) = 0[/tex]

This implies that,

[tex] \frac{3}{4} x = \frac{ \pi}{2} [/tex]

[tex]x = \frac{ \pi}{2} \times \frac{4}{3} [/tex]

[tex]x = \frac{2\pi}{3} [/tex]

Or

[tex]\frac{3}{4} x = - \frac{ \pi}{2} [/tex]

[tex]x = \frac{ - \pi}{2} \times \frac{4}{3} [/tex]

Answer:

First question

a = 1 , h = 0 , k = 6 ⇒ third answer

Second question

y = 2x² + 4 ⇒ second answer

Third question

No of the choices correct ⇒ fourth answer

Step-by-step explanation:

First question

∵ f(x) = x² + 6

- It is a quadratic function with general form ax² + bx + c

- Its vertex is (h , k), where h = -b/2a and k = f(h)

∵ a = 1 , b = 0 , c = 6

∴ h = 0/2(1) = 0

∴ f(0) = 0² + 6 = 6

∴ a = 1 , h = 0 , k = 6 ⇒ third answer

Second question

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

∵ y = 2x²

∵ y is shifted 4 units up

∴ k = 4

∴ y + 4 = 2x² + 4

∴ y = 2x² + 4 ⇒ second answer

Third question

∵ y = -2x² + 3

- It is a quadratic equation with general form ax² + bx + c

- It represented graphically by parabola

- If a is positive the parabola opens upward

- If a is negative the parabola opens downward

∵ a = -2

∴ The parabola opens downward

∴ No of the choices correct ⇒ fourth answer

The area of a triangle with a base of 6 cm and height of 8 cm, is 24 cm²

Area is the amount of space occupied by a two dimensional shape or object.

The area of a triangle is given by:

Area of triangle = (1/2) * base * height

Assume the triangle has a base of 6 cm and height of 8 cm, hence:

Area of triangle = (1/2) * 6 * 8 = 24 cm²

Answer:

Step-by-step explanation:

1. First, put together the information we have. Total = 121. Emily has 40% more than Carl, and Carl has 60% more than Antony.

2. Next, set each person as a variable. Antony = x. Carl = 1.6x. Emily = 1.4 times 1.6x.

3. Next, form an equation using these variables.

    x + 1.6x + (1.4 x 1.6x) = 121

    x + 1.6x + 2.24x = 121

    4.84x = 121

    x = 25

4. Finally, plug in x to our previous variables in step #2 to find the number of stamps Emily and Carl have.

Antony: x = 25 stamps

Carl: 1.6x = 40 stamps

Emily: 1.4 times 1.6x = 56 stamps

Answer:

21π m, or ≈ 65.94 m

Step-by-step explanation:

Remember that π is the ratio between a circle's circumference and its diameter, or, in equation form:

[tex]\pi=\frac{c}{d}[/tex]

where c is the circumference and d is the diameter. If we want to find the circumference, we can just multiply that equation by d on both sides to get

[tex]c=\pi d[/tex]

Here, our d = 21 m, so our circumference would be

[tex]c=21\pi[/tex] m, or approximately 21(3.14) = 65.94 m

____________________________________________________

Answer:

7 dollars

____________________________________________________

Step-by-step explanation:

To make solving this equation easier, lets turn the the information we got in the question into an actual equation.

Key information:

4 tickets

$12 popcorn

Spent a TOTAL of $40.

With the information above, we can use it to make an equation.

We would use the equation: y = mx + b

Since our "y" value would represent our total value, our total value is 40, so we would plug 40 into y.

Your equation should look like this:

40 = mx + b

Our "b" value represents our start value, and our start value would be 12 because we started with one $12 popcorn.

Your equation should look like this:

40 = mx + 12

Our "m" value would represent how many tickets we bought, so we would plug in 4 in m.

Our equation would be:

40 = 4x + 12

Now we can solve the equation:

We would move the 12 over to the left side of the equal sign by subtracting, then we would divide by 4.

[tex]40=4x+12\\\\28=4x\\\\7=x[/tex]

We should get ther answer of 7, that means that each ticket cost $7 dollars.

7 dollars should be your FINAL answer.

____________________________________________________

Answer:

One ticket = $7

Step-by-step explanation:

Forming the equation,

→ 4x + 12 = 40

Now the value of x will be,

→ 4x + 12 = 40

→ 4x = 40 - 12

→ x = 28/4

→ [ x = 7 ]

Hence, the value of x is 7.

Answer:

The base b is 6m

Step-by-step explanation:

The area A of a triangle with base b and height h is given by the formula;

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

The area of the triangle is given as 45 while the height h is 15. We substitute these known values into the formula above and solve for the unknown base;

[tex]45=\frac{1}{2}*b*15\\\\90=15*b[/tex]

We finally divide both sides by 15 to solve for b;

b = 90/15 = 6

Therefore, the base of the triangle is 6 m

Answer:

[tex]b = 6\ m[/tex]

Step-by-step explanation:

The area of a triangle is

[tex]A = 0.5b * h[/tex]

Where b is the base of the triangle and ha is the height.

In this case we have a triangle with area

[tex]A = 45\ m ^ 2[/tex]

and with height:

[tex]h = 15\ m[/tex]

So the base of the triangle is:

[tex]45 = 0.5b (15)\\\\b=\frac{45}{15*0.5}\\\\b=6\ m[/tex]

Finally the base of the triangle is b = 6 meters

Answer:

-51, -41, -38, 13, 41, 50

Step-by-step explanation:

The integers ordered from least to greatest are: -51, -41, -38, 13, 41, 50.

To order the integers from least to greatest, one must start by identifying the negative integers and then the positive integers. Among negative integers, the larger the absolute value, the smaller the number. Conversely, for positive integers, the larger the number, the greater it is.

Starting with the negative integers:

-51 is the smallest because it has the largest absolute value among the negative numbers.

-41 is the next smallest negative number.

-38 is the smallest negative number because it has the smallest absolute value among the negatives.

Now, moving on to the positive integers:

13 is the smallest positive number.

41 is the next smallest positive number.

50 is the largest positive number.

Putting it all together:

-51, -41, -38, 13, 41, 50.

The explicit formula is:

[tex]a_n = 200 +5(n-1)[/tex]

Step-by-step explanation:

Freya increases 5 yards daily to the number of yards she runs.

Note that the increase factor is constant, so this problem can be modeled using an arithmetic sequence.

The explicit formula for an arithmetic sequence is:

[tex]a_n = n_1 + d(n-1)[/tex]

Where:

[tex]a_n[/tex] is the number of yards that Freya runs on the day

[tex]a_1[/tex] is the number of yards that he runs on day 1

d is the increase factor. [tex]d = 5[/tex] yards

n is the number of days

Then as [tex]a_1 = 200[/tex] and [tex]d = 5[/tex], the explicit formula is:

[tex]a_n = 200 +5(n-1)[/tex]

Answer:

The domain of (f*g) (x) is the set of all real numbers; ( -∞, ∞)

Step-by-step explanation:

(f*g) (x) simply means we obtain the product of f(x) and g(x). We are given that;

f(x)=2x

g(x)= 1/x

(f*g) (x) = f(x) * g(x)

(f*g) (x) = 2x * 1/x = 2

This is a horizontal line defined everywhere on the real line. The domain of  (f*g) (x) is thus ( -∞, ∞)

Answer:

All real numbers

Step-by-step explanation:

Given : [tex]f(x)=2x[/tex]

           [tex]g(x)= \frac{1}{x}[/tex]

To Find : the domain of (f*g) (x)

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

[tex]g(x)= \frac{1}{x}[/tex]

[tex](f\cdot g)(x)=2x \times \frac{1}{x}[/tex]

[tex](f\cdot g)(x)=2[/tex]

Since the value of [tex](f\cdot g)(x)=2[/tex]

So, the domain of the function is [tex](f\cdot g)(x)[/tex] is all real numbers .
