i need help with this question asap pls ​

Step-by-step explanation:

Let first find the x and y xomponets.

X componets is 8 and the y componets is -7 so

[tex]r = \sqrt{ {x}^{2} + {y}^{2} } [/tex]

[tex]r = \sqrt{ 64 + 49} [/tex]

[tex]r = \sqrt{113} [/tex]

[tex] \csc(x) = \frac{r}{y} [/tex]

So

[tex] \csc(x) = - \frac{ \sqrt{113} }{ 7} [/tex]

Presumably, the first limit is some finite number

[tex]\displaystyle \lim_{x\to\pi} \frac{f(x)}{x-\pi} = c[/tex]

Since x - π clearly approaches 0 as x approaches π, we must also have f(x) approaching 0,

[tex]\displaystyle \lim_{x\to\pi} f(x) = 0[/tex]

Recall the double angle identity,

sin(2t) = 2 sin(t) cos(t)

and rewrite the limit as

[tex]\displaystyle \lim_{x\to\pi} \frac{\sin(2 f(x))}{x - \pi} = \lim_{x\to\pi} \frac{2 \sin(f(x)) \cos(f(x))}{x - \pi} = 2 \lim_{x\to\pi} \frac{\sin(f(x))}{f(x)} \times \frac{f(x) \cos(f(x))}{x - \pi}[/tex]

Recall that

[tex]\displaystyle \lim_{x\to0}\frac{\sin(x)}x=1[/tex]

which means

[tex]\displaystyle \lim_{x\to\pi}\frac{\sin(f(x))}{f(x)} = \lim_{f(x)\to0}\frac{\sin(f(x))}{f(x)} = 1[/tex]

and by continuity,

[tex]\displaystyle \lim_{x\to\pi} \cos(f(x)) = \cos\left(\lim_{x\to\pi} f(x)\right) = \cos(0) = 1[/tex]

Then

[tex]\displaystyle 2 \lim_{x\to\pi} \frac{\sin(f(x))}{f(x)} \times \frac{f(x) \cos(f(x))}{x - \pi} \\\\ = 2 \left(\lim_{x\to\pi}\frac{\sin(f(x))}{f(x)}\right) \left(\lim_{x\to\pi} \frac{f(x)}{x-\pi}\right) \left(\lim_{x\to\pi}\cos(f(x))\right) \\\\ = 2 \times 1 \times c \times 1 = \boxed{2c}[/tex]

Answer: 108

Step-by-step explanation: Let the total number of sweets be x

Therefore, Anna  - (x/3)+8

After Anna, remaining amount is x - ((x/3)+8) = 2x/3 + 8

Betty took (2x/3 + 8)/2 + 18 = x/3 + 22

Remaining = x - ((x/3)+8) - (x/3 + 22) = x/3 -30

Candy took the rest which is 6 i.e.

x/3 - 30 = 6

x/3 = 36

x = 108

Answer:

x = 15/8

Step-by-step explanation:

Let x = unknown number

Given:

some number minus -15 is equal to the product of the number and 9

⇒ x - -15 = x · 9

⇒ x + 15 = 9x

⇒ 15 = 9x - x

⇒ 15 = 8x

⇒ x = 15/8

Answer:

15/8

Step-by-step explanation:

Let's assume that the number is 'n'. Provided that number 'n' minus -15 is equal to the product of the number 'n' and 9. Simply jot down the above statement in mathematical form:

[tex] \implies\:\sf{\red{n \: - \: ( - 15) \: = \: n \: \times \: 9}}[/tex]

Now, simply solve the above equation.

[tex]\implies\:\sf{n \: + \: 15 \: = \: 9n}[/tex]

Take the like terms on one sides.

[tex]\implies\:\sf{9n \: - \: n \: = \: 15}[/tex]

Do the rest calculations.

[tex]\implies\:\sf{8n \: = \: 15}[/tex]

[tex]\implies\:\sf{\red{n \: = \: \dfrac{15}{8}}}[/tex]

Hence, the required value of n is 15/8.

Answer:

the answer is 48.139 in²

Step-by-step explanation:

I took the test.

48.139 in² of the figure area is painted yellow in color.

An area is amount of space occupied by a two dimensional shape or object.

The area of the figure = Area of the square + Area of the triangle

Area of the figure = (7 in * 7 in) + (1/2) * (12 * 7) = 91 in²

Since 52.9% of the area is painted yellow, hence:

Area painted yellow = 52.9% of 91 = 48.139 in²

48.139 in² of the figure area is painted yellow in color.

Answer:

768$

Step-by-step explanation:

I multiplied 24$ times 32.

The polynomial that represents the length is:

h(x) = 11x + 1.

We know that the area of the top surface is given by:

f(x) = 66x^2 + 17x + 1

And the width of the top surface is:

g(x) = 6x + 1.

We can assume that the length, h(x), is another polynomial of degree 1, so we can write:

h(x) = a*x + b

Now, the area is the product of the width and the length, so we have:

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

f(x) = (6x + 1)*(ax + b)

     =   6ax^2 + (6b)x + (a)x + b

     =   (6a)x^2 + (6b + a)x + b

Now let's compare this with f(x), correspondent coefficients must have the same value.

66x^2 + 17x + 1 = (6a)x^2 + (6b + a)x + b

Then we have:

66 = 6a

17 = 6b + a

1 = b

From the first equation we have:

66/6 = a = 11

And from the third:

b = 1

Then the length is:

h(x) = 11x + 1.

The profit function of the company is the difference between the cost and the revenue functions of the company

The given parameters are:

C(x) = 60x + 300 --- the cost function

R(x) = 100x - 0.5x^2 ---- the revenue function

The profit function is calculated as:

P(x) = R(x) - C(x)

So, we have:

[tex]P(x) = 100x - 0.5x^2 - 60x - 300[/tex]

Rewrite as:

[tex]P(x) = - 0.5x^2 + 100x - 60x - 300[/tex]

[tex]P(x) = - 0.5x^2 + 40x - 300[/tex]

This means that the expression of the profit function is [tex]- 0.5x^2 + 40x - 300[/tex]

This means that:

P(x) = 50

So, we have:

[tex]- 0.5x^2 + 40x - 300 = 50[/tex]

Subtract 50 from both sides

[tex]- 0.5x^2 + 40x - 350 = 0[/tex]

Multiply through by -2

[tex]x^2 - 80x + 700 = 0[/tex]

Expand

[tex]x^2 - 70x - 10x + 700 = 0[/tex]

Factorize

[tex]x(x - 70) - 10(x - 70) = 0[/tex]

Factor out x - 70

[tex](x - 10)(x - 70) = 0[/tex]

Solve for x

x = 10 or x = 70

Hence, the two values of x that creates a profit of $50 are x = 10 and x = 70

y'' + 5y' + 6y = 0

has characteristic equation

r² + 5r + 6 = (r + 2) (r + 3) = 0

with roots at r = -2 and r = -3, hence the differential equation's characteristic solution is

[tex]y(t) = C_1 e^{-2t} + C_2 e^{-3t}[/tex]

Given that y(0) = 1 and y'(0) = 2, we have

[tex]y(t) = C_1 e^{-2t} + C_2 e^{-3t} \implies 1 = C_1 + C_2[/tex]

[tex]y'(t) = -2C_1 e^{-2t} - 3C_2 e^{-3t} \implies 2 = -2C_1 - 3C_2[/tex]

and solving the resulting system of equations yields C₁ = 5 and C₂ = -4.

So the particular solution to the ODE is

[tex]\boxed{y(t) = 5 e^{-2t} - 4 e^{-3t}}[/tex]
