Please help me, this is my last question and I’ve been trying all day
aalyn [17]

Answer:

sqrt(x-3)+3

Step-by-step explanation:

Consider the graph of a function f(x), if we want to move the graph right by a units we have f(x-a), to then move it up by b units we have f(x-a)+b. In this case you replace the x with x-a to get sqrt(x-a)+b

Notice how the graph goes through (3,3) and (4,4) like the original graph goes through (0,0) and (1,1). This means we want to translate it 3 up and 3 right giving us the answer.

Marcus, Shaun, and Tristan each invested into new business. They invested 1 point
Schach [20]

Shaun invested $176,250 into the new business.

Marcus invested half of the $940,000 so the amount that Shaun and Tristan invested is:

= 940,000 / 2

= $470,000

Shaun and Tristan invested in the ratio 3:5.

The amount that Shaun invested is:

<em>= (Ratio of Shaun / Sum of the ratios) x Amount both invested </em>

= (3 / (3 + 5 )) x 470,000

= 3/8 x 470,000

= $176,250

In conclusion, Shaun must have invested $176,250 into the business.

C2d3 has a solubility product constant of 9.14×10−9. what is the molar solubility of c2d3?
UkoKoshka [18]
The correct answer for the question that is being presented above is this one:

We need to express the ksp expression of C2D3
<span>C2D3
= (2x)2(3x)3
= 108x5 </span>

<span>Then set that equation equal to your solubility constant </span>

<span>9.14x10-9 = 108x5 </span>
<span>x = 9.67x10-3 
</span>
<span>So the molar solubility is 9.67x10-3</span>
