Part B If m=18, what must be the value of n for the equation to have infinitely many solutions? Explain your answer
djverab [1.8K]

The equation have infinitely many solution when n is equal to -15.41.

<h3>What is linear equation?</h3>

A linear equation in one variable is an equation which has a maximum of one variable of order 1. It is of the form ax + b = 0, where x is the variable. This equation has only one solution.

Given equation is;

24( mx + n ) = 3x + 17

where; m and n are real numbers.

Part 1.  If m = 14 and n = 13 then

Putting the value of m and n in the equation we get;

= 24( 14.x + 13 ) = 3x + 17

=  336x + 312 = 3x + 17

=  336x - 3x = 17- 312

=  333x = -295

x = 0.886

Hence,  x = 0.886  the equation having one solution .

part 2.  if m = 18 then to find n .

put m = 18 in the given equation;

= 24(18.(0.886) + n ) = 3(0.886) + 17

= 24(15.94) + 24n = 2.658 + 17

= 382.56 + 24n = 19.658

= 24n = 19.658 - 382.56

n = -15.41

Hence, The equation have infinitely many solution when n is equal to -15.41.

faust18 [17]

Answer:

The large pack is a better deal!

so first we need to figure out how much the individual beads cost.

Small pack: $ 3.60÷90 = 0.04 cents per bead

Large pack: $9.00 ÷ 300 = 0.03 cents per bead

Hope this helps!!

Have a great day!!

Can someone pls help me find the second derivative of this. I need to find the concave up and down intervals but I’m having trou
KonstantinChe [14]

Starting from

f(x)=\dfrac14(x+1)^{\frac83}-4(x+1)^{\frac23}

take the first derivative using the power and chain rules:

f'(x)=\dfrac83\cdot\dfrac14(x+1)^{\frac83-1}-\dfrac23\cdot4(x+1)^{\frac23-1}

f'(x)=\dfrac23(x+1)^{\frac53}-\dfrac83(x+1)^{-\frac13}

Now take the second derivative:

f''(x)=\dfrac53\cdot\dfrac23(x+1)^{\frac53-1}-\left(-\dfrac13\right)\cdot\dfrac83(x+1)^{-\frac13-1}

f''(x)=\boxed{\dfrac{10}9(x+1)^{\frac23}+\dfrac89(x+1)^{-\frac43}}

Optionally, you can condense the second derivative a bit by factoring out \frac89(x+1)^{-\frac43}, which gives

f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^{\frac63}+1\right)

f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^2+1\right)

f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80x^2+160x+81\right)
