Step-by-step explanation:
Alright!
we are expected to model the total amount of money Myles have\
firstly he has with him $635
and he is earning $120 weekly
Say the number of weeks he worked is given is n
and let the amount of money Myles will have after n weeks be y
hence we can now model the equation to represent how much Myles will have after n weeks
The expression is same as the equation for a straight line
i.e
The equation of a circle exists:
, where (h, k) be the center.
The center of the circle exists at (16, 30).
<h3>What is the equation of a circle?</h3>
Let, the equation of a circle exists:
, where (h, k) be the center.
We rewrite the equation and set them equal :
We solve for each coefficient meaning if the term on the LHS contains an x then its coefficient exists exactly as the one on the RHS containing the x or y.
-2hx = -32x
h = -32/-2
⇒ h = 16.
-2ky = -60y
k = -60/-2
⇒ k = 30.
The center of the circle exists at (16, 30).

Answer:
no and yes. No because you got a good grade and yes because this is 10% of your grade, But even if it goes down it wouldn't make you fail or go down by a lot of %.
Well, rotational symmetry is an object that looks the same after a certain amount of turning. The letters: H, I, N, O, S, X, Z, have rotational symmetry. These letters all need to be turned 180 degrees.
Hope this helps! :)
Answer:
2260.8 ft ^ 2 / s
Step-by-step explanation:
To solve the problem we first know that:
dr / dt = 6 ft / s
r = 60 ft
Now they ask us for dA / dt, the change of the area with respect to time, by chain rule we have to:
dA / dt = dA / dr * dr / dt
we have that A = pi * r ^ 2
d (pi * r ^ 2) / dr
deriving the above we are left with:
2 * pi * r
replacing:
dA / dt = (2 * pi * r) * 6
dA / dt = 2 * 3.14 * 60 * 6
dA / dt = 2260.8 ft ^ 2 / s
therefore the area change per second is 2260.8 ft ^ 2 / s
