3 zinc/11 copper = x zinc/264 copper
3/11 = x/264
11x = 792
x = 72 grams of zinc

Answer: labor force participation rate =60%

unemployment rate = 6.67%

Step-by-step explanation:

The labor force participation rate is computed as

$\text{labor force participation rate}=\dfrac{\text{Total employed persons}}{\text{Total population}}$

i.e. $\text{labor force participation rate}= \dfrac{72000}{120000}$

$= 0.6\ or\ 60 \%$

The unemployment rate is computed as:

$\text{unemployment rate}=\dfrac{\text{Number of personsdon't have jobs }}{\text{Total population}}\\\\\text{unemployment rate}=\dfrac{8000}{120000}\\\\\text{unemployment rate}=0.0667\ or\ 6.67\%$

Hence, labor force participation rate =60%

unemployment rate = 6.67%

I need to know how to simplify this equation

ArbitrLikvidat [17]

$\frac{ {3}^{x + 4} - {3}^{2x + 2} }{ {3}^{x - 2} \times {3}^{x + 4} } = \frac{x + 4 - 2x - 2}{(x - 2) \times (x + 4)} = \frac{ - x + 2}{ {x}^{2} + 4x - 2x - 8 } = \frac{ - x + 2}{ {x}^{2} + 2x - 8}$
i could be wrong, was kinda in a rush

If the graph of the function f has a multiple zero at x = 2, what is a possible exponent of the factor x - 2? Justify your reaso

melomori [17]

Answer:

$(x-2)^2$

The exponent is 2.

Step-by-step explanation:

Remember multiplicity rules:

If a factor has an odd multiplicity (e.g. it is raised to 1, 3, 5...) then it will cross the x-axis.
If a factor has an even multiplicity (e.g. it is raised to 2, 4, 6...) then it will bounce off the x-axis.

At x=2, we have the factor (x-2).

From the graph, we can see that the graph bounces off at that point.

Hence, the multiplicity of (x-2) must be even.

Therefore, a possible exponent for the factor (x-2) is 2. Any even number will suffice.
