Answer:

$x=6$

Step-by-step explanation:

The lengths of line segments $\overline{AB}$ and $\overline{AC}$ because of the two segments and two angles marked as equal in the diagram. Because of this, the arcs $\widehat{AB}$ and $\widehat{AC}$ are equal.

Since there are 360 degrees in a circle, we can now set up the following equation:

$(10x-23)+(10x-23)+106=180,\\20x-46+106=180,\\20x+60=180,\\20x=120,\\x=\boxed{6}$

Find a polynomial function with leading coefficient 1 that has the given zeros, multiplicities, and degree. zero: 1, multiplicit

vfiekz [6]

Polynomial expression for the given conditions is formulated in the equation

y(x)=1*(x-2)^3(x-0)^2

The polynomial for the conditions with leading coefficient 1 that has the given zeros, multiplicities, and degree. Zero: 2, multiplicity: 3 Zero: 0, multiplicity: 2 Degree: 5 is given as

According to the given condition

The given conditions to write the polynomial equations are as follows

Zero 2 and Multiplicity 3

Zero 0 and Multiplicity 2

Degree of polynomial expression = 5

The leading coefficient of polynomial expression = 1

Let us consider the polynomial equation has only one variable and hence in the general form we can write the equation of polynomial as follows

From the general form of polynomial expression as shown in equation (1) we can write

Polynomial expression for the given conditions is formulated in the equation

y(x)=1*(x-2)^3(x)^2-------(2)

So the polynomial for the conditions given in the question is expressed as

y(x)=1*(x-2)^3(x)^2

Simplify 9x - 4 + 3x

rewona [7]

Answer:

$4(3x - 1)$

Step-by-step explanation:

$9x - 4 + 3x$

Adding 9x & 3x gives 12x.

$= > 12x - 4$

Now taking 4 common from both the terms , we get :-

$4(3x - 1)$

For the equation given below, evaluate y′ at the point (−2,−1).<br><br> 3xy−3x−12=0.

SSSSS [86.1K]

Answer:

Y'=3xy-3x-12

Y'=F(-2,-1)=0

Step-by-step explanation:

The function of the equation at the point (-2,-1)

is where the equation make the function go to zero:

Y'=3xy-3x-12

Y'=F(-2,-1)=[3(-2)(-1)]-[3(-1)]-12

F(-2,-1)=[6]-[-6]-12

F(-2,-1)=6+6-12

F(-2,-1)=12-12

F(-2,-1)=0

Solving for y

3xy-3x-12=0

y=4/x+x

Making y=0

$\frac{4}{x}+x=0$

$x^{2} =-4$

$x=-2$

So the values make the function go to zero
