Answer:
C(5,-9) and r=8.
Step-by-step explanation:
C(p, q) - center
r=radius
k:x^2 +y^2 +dx+ey+f=0
x^2+y^2 - 10x+18y+42=0
d=-10, e=18, f=42
p=-d/2=-(-10)/2=10/2=5
q=-e/2=-18/2=-9
r^2 =p^2+q^2-f
r^2 =5^2 +(-9)^2 - 42
r^2=25+81-42
r^2 =106-42
r^2 =64
r=sqrt(64)
r=8
C(p,q)=C(5,-9) r=8
Answer:
42
Step-by-step explanation:
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(2)(3)
A = 3
<u>Area of rectangle:</u>
A = bh
A = 11(3)
A = 33
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(3)(4)
A = 6
<u>Combined:</u>
3 + 33 + 6
42

Answer:
The exact solution is

And the approximation to three decimal places is:
x = 0.363
Step-by-step explanation:
Here we have the equation:

Now we can remember a property of the natural logarithm function:
Ln(a^n) = n*Ln(a)
Now we can apply the Ln( ) function to both sides of that equation to get:

Then we get:

Solving that for x we get:

So the exact solution is:

And the approximation to three decimal places is:
x = 0.363
396,000
because 5 goes up and anything lower than five stays the same
