Answer:

perimeter of circle=2πr

16=2πr

r=16/2π=8/πcm

now.

area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²

What is the solution to the equation StartFraction 1 Over h minus 5 EndFraction + StartFraction 2 Over h + 5 EndFraction = Start

djyliett [7]

Answer:

h=7

Step-by-step explanation:

We want to solve the equation:

$\frac{1}{h-5}+\frac{2}{h+5}=\frac{16}{h^2-25}$

We multiply through by the LCM: $h^2-25=(h+5)(h-5)$

$(h^2-25*\frac{1}{h-5}+(h^2-25)*\frac{2}{h+5}=\frac{16}{h^2-25} \times(h^2-25)$

Simplify to get:

$h+5+2(h-5)=16$

We expand to get:

$h+5+2h-10=16$

$h+2h=16+10-5$ $3h=21$

h=7

Consider the function represented by the equation y-6x-9=0. Which answer shows the equation written in function notation with x

spin [16.1K]

we have

$y-6x-9=0$

Step $1$

Clear the variable y

$y-6x-9=0$

Adds $(6x+9)$ both sides

$y-6x-9+(6x+9)=0+(6x+9)$

$y=(6x+9)$

Step $2$

Convert in function notation

Let

$f(x)=y$

$f(x)=(6x+9)$

therefore

the answer is

$f(x)=(6x+9)$
