QUESTION POSTED AT 28/01/2020 - 01:06 AM

Terri is analyzing a circle, y2 + x2 = 36, and a linear function g(x). Will they intersect? y2 + x2 = 36 g(x) graph of the function y squared plus x squared equals 36 x g(x) −4 −4 −2 −2 2 2 Yes, at positive x-coordinates or zero Yes, at negative x-coordinates or zero Yes, at negative and positive x-coordinates or zero No, they will not intersect

Answer:

The graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

Step-by-step explanation:

The equation of circle is given as:

x^2+y^2=36

also the graph of the function g(x) is given by:

We are given a set of values in a table as:

  x         g(x)

−4       −4

 −2        −2

   2          2

Hence, the function g(x) could be computed with the help of slope intercept form of a equation as:

y=mx+c; where m denotes the slope of the line and c denotes the y intercept.

when x=-4 g(x)=y=-4

-4=-4m+c

also when x=-2 then y=g(x)=-2

-2=-2m+c

on solving the above two equations using elimination method we get,

m=1 and c=0

hence, y=g(x)=x

Now we are asked tgo find whether the graph of the circle and g(x) intersect each other or not.

Clearly from the graph we could see that the graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

That would be C.

20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10

If a is a rational number and b is a rational number, why could c be an irrational number? represents the solution set of the compound inequality mc011-1.jpg?

Because even though 'a' and 'b' are rational, and their squares are

√5 is irrational

How many solutions exist for the given equation? 12x + 1 = 3(4x + 1) – 2

Answer:

There are infinite number of solution

Step-by-step explanation:

We have to tell the number of solution of given equation

                         12x+1=3(4x+1)-2

We solve the expression on the right hand side

i.e.   3(4x+1)-2

=  12x+3-2

= 12x+1

Which is equal to the expression on the left hand side.

Hence, for any value of x right hand side equals left hand side

Hence, there are infinite number of solution

Find the range of the function f(x)=4x-1 for the domain {-1,0,1,2,3}.

Answer:

Range defined as the complete set of possible values of the dependent variable,

or

The range is defined as the resulting y-values we get after substituting all the possible values of x from domain.

Given the function: f(x)=y = 4x-1

Also, x ∈Domain = {-1, 0, 1, 2, 3}

For x = -1;

y = 4(-1)-1 = -4 -1 = -5

For x = 0;

y = 4(0)-1 = 0 -1 = -1

For x = 1;

y = 4(1)-1 = 4-1 =3

For x = 2;

y = 4(2)-1 = 8-1 =7

For x = 3;

y = 4(3)-1 = 12-1 =11

Therefore, the range of the function are the set of all values of y i,e  

Range = {-5, -1, 3, 7 , 11}

You skiped one operator.

I assume that the function is f(n+1) = f(n) - 2.

f(1) = 10
f(2) = f(1) - 2 = 10 - 2 = 8
f(3) = f(2) - 2 = 8 - 2 = 6
f(4) = f(3) - 2 = 6 - 2 = 4
f(5) = f(4) - 2 = 4 -2 = 2

So the sequence, is 10, 8, 6, 4, 2, ... [option d]

The value of x in this system of equations is 1. 3x y = 9 y = –4x 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x (–4x 10) = 9 –x 10 = 9 –x = –1 x = 1 what is the value of y?

We have two unknowns from the equation therefore, two equations are needed. These equations are:

3x + y = 9
y = –4x +10 

To solve for y, we first substitute the second equation to the first one.
3x + –4x +10= 9 
x = 1

We substitute the value of x to either of the equations and solve for y.

y = –4(1) +10 
y = 6

Solomon needs to justify the formula for the arc length of a sector. which expression best completes this argument? the circumference of a circle is given by the formula c=pi * d , where d is the diameter. because the diameter is twice the radius, c= 2 * pi * r. if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to 360°/n° the arc length of each sector is the circumference divided by the number of sectors, or _____. therefore, the arc length of a sector of a circle with a central angle of n° is given by 2*pi*r*n/360 or pi*r*n/180 . a. 2*pi*r/270/n b. 2*pi*r/360/n c. 2*pi*r/180/n d. 2*pi*r/90/n

Answer:  The answer is (b). \dfrac{2\pi r}{\frac{360^\circ}{n^\circ}}.


Step-by-step explanation: Let us consider a circle with centre "O" and radius OA=OB=r units. We know that the circumference of a circle is 2\pi\times radius~of~the~circle, so the circumference of Circle 'C' is given by

Circumference=2\pi r.

Also, let us central angles of equal size of 'n°', the the number of sectors formed is given by

no.~of~sectors=\dfrac{360^\circ}{n^\circ}.

Now, the formula for arc length of a sector is given by

arc~length~of~of~a~sector=\dfrac{Circumference~of~the~circle}{no.~of~equally~sized~sectors}.

arc~length~of~of~a~sector=\dfrac{2\pi r}{\frac{360^\circ}{n^\circ}}.

Thus, (b) is the correct option.

x+2----> the second consecutive odd number

we know that

solve for x

Multiply by 3 both sides

3x+(x+2)=150

4x=148
