Answer:
$3781.19
Step-by-step explanation:
Let us assume that the student has to earn $(1900 + x) by September 1 so that he can pay the $1900 tuition fee by September 1 and the remaining $x will grow at 3% simple interest to make him able to pay another tuition fee of $1900 by January 1.
So, we can write 
{Because September 1 to January 1 is 4 months and the monthly simple interest rate is 
%}
⇒ 1.01x = 1900
⇒ x = $1881.19 (Rounded to the nearest cents)
Therefore, the student has to earn $(1900 + 1881.19) = $3781.19 (Answer)
Answer:
yes, y=2x-3 is linear
2x - y = 3 Standard Form
Step-by-step explanation:
since both the 'x' and 'y' variables have one as their exponents then this represents a linear equation
standard form: Ax + By = C
y = 2x - 3
subtract 2x from each side to get:
-2x + y = -3
divide each term by -1 to get (this is done so the leading coefficient is not negative)
2x - y = 3 Standard Form
<span>(x – h)^2 + (y – k)^2 = r<span>^2
this equation is a derivative of the equation of a circle
x^2 + y^2 = r^2
This is from the origin. If we move the in x or y then the radius will change positions in x or y
with h = -3 and k = 1
we can plug in each set of numbers and solve.
we find Z to be on the circle edge!</span></span>
Answer:
<u>Frequency = 1/period = 
</u>
Step-by-step explanation:
The frequency of the sinusoidal function = 1/period
Frequency is how many the function repeats itself per unit if time i.e: per "1"
For the given graph :
, Where: B = 2π/period
period = 2π/B , B = 1/4 = 0.25
∴ Period = 2π/0.25 = 8π
∴ Frequency = 1/period =
