Answer:
The maximum area is 1,600 square meters
Step-by-step explanation:
<u><em>The complete question is</em></u>
What is the maximum area possible?
The given function area is modeled by A(w)=-w(w-80)
we know that
The given function is a vertical parabola open downward
The vertex is a maximum
The x-coordinate of the vertex represent the width for the maximum area
The y-coordinate of the vertex represent the maximum area
Convert the quadratic function in vertex form
Factor -1
Complete the square
Rewrite as perfect squares
----> function in vertex form
The vertex is the point (40,1,600)
therefore
The maximum area is 1,600 square meters
<span>assume the graduate put the purchase on his card.thenInitial balance = $8000 on the first statement (+fees and interest charges, if any)That means he owes the card issuer $8000.Credit balance is what the issuer owes the card holder, which is zero
</span> option "c. $8000" is your answer
Answer:
It is not. Also use ^2 to represent squaring a number.
Step-by-step explanation:
First, USE ^2 FOR SQUARED
It is not correct.
The standard equation of a circle is (x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius.
In your question the center is (-2,3) and the radius is the length of the line segment from the center to any pointon the circle. nd hey, it tells us a point on the circle is (-2,6).
Let's take it one part at a time. we know h and k so let's plug them in.
(x-h)^2 + (y-k)^2
(x-(-2))^2 + (y-3)^2
(x+2)^2 + (y-3)^2
now r is the length of the line segment from (-2,3) and (-2,6). To get from (-2,3) to (-2,6) hopefully it is pretty obvious you just move up (so int he y direction) 3 spaces. this makes r = 3. int he formula we want r^2 and that is 9. The result is that the circle has a formula of:
(x-h)^2 + (y-k)^2 = r^2
(x+2)^2 + (y-3)^2 = 9
The formula Juanita got is actually a hyperbola.
Answer:
Company A is a better deal than Company B for the number of miles greater than 295 miles
Step-by-step explanation:
Let
y ----> the charge per week in dollars
x ----> the number of miles
we have
<em>Company A</em>
-----> equation A
<em>Company B</em>
-----> equation B
Solve the system by substitution
Equate equation A and equation B and solve for x
For x=295 miles the charge in Company A and Company B is the same
therefore
Company A is a better deal than Company B for the number of miles greater than 295 miles
Answer:
Step-by-step explanation:
The density of an object can be found by taking its mass and dividing by its volume.
Hence if density is D , Mass is M and Volume is V
a)
M = 500 gms
V = 40 cubic cm
b)
M = 125 gms
V = 1.4 cubic cm
D =89.28 gm per cc
