Hello,
if the question is to solve the equation:
1) log must exist:
a)==>2r²-27>0==>(r-√(27/2))(r+√(27/2))==> outside the roots
r<-√(27/2) or r>√(27/2)
b)==>3r²+12r>0 ==>3r(r+4)>0 ==>outside the roots
r>0 or r<-4
==>r<-4 or r>√(27/2)=3.6742...
If this is realized:
2r-27=3r²+12r
==>r²+12r+27=0
Δ=12²-4*27=36=6²
r=(-12+6)/2=-3 or r=(-12-6)/2=-9
One solution r=-9
Proof
The solution would be like this for this specific problem:
Given:
Total amount of the house
= £234,900
<span>Find:
Amount of deposit paid = ?</span>
So first, we divide the t<span>otal amount of the house by the percent of
deposit that Carol paid.
</span>= £234,900 / 10%
= £23,490
<span>Another way to solve this
is by converting the percent of the deposit into a decimal. We do this by
dividing the percentage amount by 100.
= 10% / 100% </span>
= 0.1
Next, we multiply the
decimal equivalent of the percentage to the total amount of the house.
= £234,900 * 0.1
= £23,490
So, the amount of deposit that was paid by Carol is £<span>23,490.</span>
Answer:
.
Step-by-step explanation:
From the given table it is clear that x and y are linearly related.
Now, any two points that satisfy the relation between x and y are sufficient to express the equation.
The first two given points are (2,3), and (4,4).
Therefore, the equation is 
⇒ 
⇒ 
⇒ . (Answer)
a) The average arithmetic mean is calculated by adding all of the values and then dividing the sum by the total number of values.
Which is 200.3.
b) Assume that the new average mean is 201, then
Solve for x.
Divide by 2604 to solve for x.
So the height of the new player is 175 cm.
