Answer:
$1900
Step-by-step explanation:
Starting from the equation of simple interest, which is defined as follows:
I = P * r * t
Being I the interest, P the value of the product, r the interest rate and t would be time.
We want to know the price of the product, therefore, solving the equation we have:
P = I / r * t
We know each other's values so we replace:
P = 1026 / (0.135 * 4)
P = $ 1900 was the value of the refrigerator Jaime bought
The interest is simple
A=5,200×(1+0.04×5)
A=6,240
Hello,
Since 3sin x-4sin^3x=sin (3x) (*****)
3sin x-4sin^3x=-1
==>sin (3x)=-1
==>3x=3π/2 +2kπ
==>x=π/2+2kπ/3, k being an integer
(*****)
sin (3x)=sin(x+2x)=sin x cos2x+cos x sin 2x
=sin x(cos²x-sin²x)+2cos²x sin x
=sin x(cos²x+2cos²x-sin²x)
=sinx(3(1-sin²x)-sin²x)
=3sin x-4sin^3x
Answer:
B. The graph will be compressed vertically.
Step-by-step explanation:
The given function is f (x) = x²
The new function is f 1 (x) = 1/4 x².
The general function of the form is f(x) = a · x²
i) If |a| < 1 the graph is compressed vertically by a factor of a.
ii) If |a| > 1 the graph is stretched vertically by a factor of a.
Here: a = 1/4 < 1
Answer:
B. The graph will be compressed vertically.
Hope this will helpful.
Thank you.
