Mai says that the equation 2x+2=x+1 has no solutions because the left side is double the right side. Do you agree with mai provi
attashe74 [19]

2x+2=x+1 - subtract 2 from both sides

2x=x-1 - subtract x from both sides

x= -1 - solution

Let f(x)=−x√3 . What is the average rate of change of f(x) from 8 to 64?
Fed [463]

Average rate of change of the function: -\sqrt{3}

Step-by-step explanation:

The average rate of change of a function f(x) can be calculated as:

r=\frac{f(x_2)-f(x_1)}{x_2-x_1}

where:

x_1, x_2 are the x-values of the interval taken into account to evaluate the rate of change of the function

f(x_1),f(x_2) are the values of the function at those points

In this problem, we have:

x_1=8\\x_2=64

The function is f(x)=-x\sqrt{3}, so

f(x_1)=f(8)=-8\sqrt{3}\\f(x_2)=f(64)=-64\sqrt{3}

So, the average rate of change in this interval is:

r=\frac{-64\sqrt{3}-(-8\sqrt{3})}{64-8}=\frac{-56\sqrt{3}}{56}=-\sqrt{3}

A chemical company makes up batches of copper sulfate solution by adding 250 kg of copper sulfate powder to 1000 liters of water
shepuryov [24]

Answer:

  • 0.07 kg

Step-by-step explanation:

  • <em>Assuming copper sulfate has same density as water</em>

<u>Chemical to water ratio as per given is:</u>

  • 250 kg : 1000 liter = 1 kg : 4 liter

Lab solution is 350 ml

<u>Converting to same ratio as above:</u>

350/(1 + 4) = 70 ml

  • 70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 ml

Answer is 0.07 kg

seropon [69]
Complementary angles add up to 90°. The complement of a 27° angle is 90°-27°= 63°.


Supplementary angles add up to 180°. The supplement of a 27° angle is 180°-27°=153°
