How do you do solve this problem

Damm [24]

Answer:

Step-by-step explanation:

1cm = 10mm

Therefore 8cm = 8 · 10mm = 80mm

The scale of the model

$\dfrac{model}{real}\to\dfrac{80}{0.43}=\dfrac{80\cdot100}{0.43\cdot100}=\dfrac{8000}{43}\approx186$

Just #35 please piecewise functions

saveliy_v [14]

Answer: No, the friend is correct. In any function, each input value can only lead to one output value. When you input 3 for the x-values, you would get two output values because 3 is included in both equations. To fix this, you need to have the 3 not included in one of the equations.

For example, you could say $y=\left \{ {{2x-2, x\leq 3} \atop {-3, x > 3}} \right.$ or $y=\left \{ {{2x-2, x < 3} \atop {-3, x\geq 3}} \right.$ because the input value of 3 would not be included twice.

If you look at the attached screenshot, you will see that if you keep your friend's function, inputting 3 will result in two outputs of 4 and -3, so therefore, $y=\left \{ {{2x-2,x\leq 3} \atop {-3,x\geq 3}} \right.$ cannot represent a piecewise function.
