Let f(x)=x3+9x2−81x+14. (a) Use the definition of a derivative or the derivative rules to find g

Sergeu [11.5K]

Answer:

$g=6x+18$

Step-by-step explanation:

From the question we are told that:

Function

$f(x)=x^3+9x^2−81x+14$

Generally 1st derivative f'(x) of Fuction f(x) is

$f'(x)=3x^2+2*9(x)-81$

$f'(x)=3x^2+18(x)-81$

Generally 2nd derivative f''(x) of Fuction f(x) is

Where

$f''(x)=g$

Therefore

$g=3x^2+18(x)-81$

$g=2*3x^1+18$

$g=6x+18$

find the area of a triangle when a=22 degree, b=105 degree, and b=14 30.4 units^2 32.1 units^2 31.2 units^2 34.8 units^2

mr Goodwill [35]

C = 180 - (22 + 105) = 180 - 127 = 53 degrees
Area of triangle = 1/2 ab sin C
But a / sin A = b / sin B or a = b sin A / sin B = (14 x sin 22) / sin 105 = 5.429
Therefore, Area of triangle = 1/2 x 5.429 x 14 x sin 53 = 30.4 units^2

What is the diameter of circle T?

Ratling [72]

Answer:

$Diameter = 16$

Step-by-step explanation:

Given

$\theta = 72$

$Sector = \frac{64}{5}\pi$

Required

Calculate the diameter

The area of a sector is:

$Area = \frac{\theta}{360} * \pi r^2$

Substitute values for Area and $\theta$

$\frac{64}{5}\pi = \frac{72}{360} * \pi r^2$

Divide both sides by $\pi$

$\frac{64}{5} = \frac{72}{360} * r^2$

Make $r^2$ the subject

$\frac{64*360}{5*72} = r^2$

$\frac{64*360}{360} = r^2$

$64 = r^2$

Take positive square roots of both sides

$\sqrt{64} = r$

$8 = r$

$r = 8$

The diameter is then calculated as:

$Diameter = 2r$

$Diameter = 2*8$

$Diameter = 16$

I need major help please

Ivan

Answer:

b

Step-by-step explanation:

It is asking for the value of the green box.

The distance formula is given too.

Q = (0,-a)

P = (b, -c)

d = √(b - 0)² + (-c - (-a))²

d = √b² + (-c + a)²
