Explain why 1.19 is the greatest amount of money it is possible to have without being able to make change for a dollar

Answers

Answer 1

Answer: Hello,

There are only 2 solutions for $1.19

In cents:
119=1*25+9*10+0*5+4*1
119=3*25+4*10+0*5+4*1

Thus
120=119+1=(1*25+9*10+0*5+4*1) +1 =1*25+9*10+0*5+5*1
but 1*25+7*10+0*5+5*1=100

120=119+1=(3*25+4*10+0*5+4*1)+1=3*25+4*10+0*5+5*1
but 3*25+2*10+0*5+5*1=100

So there are no solution for $1.20

Which are the roots of the quadratic function f(b) = b2 – 75? Check all that apply.

Answers

$f(b)=b^2-75\nf(b)=0\nb^2-75=0\nb^2=75\nb=\pm√(75)=\pm√(25*3)=\pm5√(3)$

Answer:

The roots of the given quadratic function $f(b) = b^2-75$ is $5√(3)\quad$ and $-5√(3)\quad$

Step-by-step explanation:

Given: Quadratic function $f(b) = b^2-75$

We have to find the roots of the given quadratic function $f(b) = b^2-75$

Since, roots of the quadratic equation is the points where the value of function is zero.

That is f(x) = 0

Consider the given function $f(b) = b^2-75$

Put f(b) = 0

$\Rightarrow b^2-75=0$

Simplify , we have,

$\Rightarrow b^2=75$

Taking square root both side, we have,

$\Rightarrow b=√(75)$

Simplify we have,

$\Rightarrow b=\pm 5√(3)\quad$

Thus, The roots of the given quadratic function $f(b) = b^2-75$ is $5√(3)\quad$ and $-5√(3)\quad$

whats the value of c?

Answers

Simplify both sides of the equation

11c+7c -13c = 115

Simplify

5c= 115

Divide both sides by 5

5c/5 = 115/5

c = 23
