Inequalitys please help
mash [69]
4|y-9| > 36
Two equations:
4(y-9)>36 then y-9>8 then y>17
4(y-9)<-36 then y-9<-8 then y<1
So, the solution is y<1 or y>17

0.5|x+2| > 6
Two equations:
0.5(x+2) > 6 then 0.5x+1>6 then x>10
0.5(x+2) < -6 then 0.5x+1<-6 then x<-14
So, the solution is: x<-14 or x>10

A circle has a circumference of 10 pi what is the length of the radius
Talja [164]
------------------------------------------------------
Formula
------------------------------------------------------
Circumference = πD

------------------------------------------------------
Find Diameter
------------------------------------------------------
10π = πD
D = 10            ← divide by π on both sides

------------------------------------------------------
Find Radius
------------------------------------------------------
Radius = Diameter ÷ 2
Radius = 10 ÷ 2
Radius = 5 

------------------------------------------------------
Answer: Radius = 5 units

Please help me solve these are quadratic equations: I​
julia-pushkina [17]

Answer:

\boxed {\boxed {\sf a= 3, b=7, c=2}}

\boxed {\boxed {\sf Y-intercept = c }}

\boxed {\boxed {\sf Minimum}}

Step-by-step explanation:

a. a, b, c

Quadratic equations in standard form are written as:

f(x)= ax^2+bx+c

The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.

f(x)= 3x^2+7x+2

a=3 \\b=7 \\c=2

b. Y-intercept

The y-intercept for a quadratic is c.

You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).

f(0)= 3(0)^2+7(0)+2

f(0)=3(0)+7(0)+2\\f(0)= 0+0+2\\f(0)=2

We know that c=2, so the y-intercept is c.

c. Maximum/minimum

The entire quadratic is positive, so the quadratic opens up and has a minimum.
