Answer:
y=x^2+7
Step-by-step explanation:
Distribute the 2nd power to the x and the 2
you will get x squared +4+3
simplify equation
y=x^2+7
that is your answer
A sinusoid is cyclical and has a period or frequency.
y = sin x is a sinusoid, with a period of 2π.
y = √x is not a sinusoid.
y = cos x is a sinusoid with a period of 2π.
Answer: y = √x is not a sinusoid.

Answer: 17.25 dollars</h3>
=======================================================
Explanation:
15% of 15 = 0.15*15 = 2.25
The cost has increased by $2.25 which means the cost per kilogram is now 15+2.25 = 17.25 dollars
------------
As a slight shortcut, we can multiply the old cost (15) by the multiplier 1.15 to get the same result:
1.15*15 = 17.25
This method allows us to chain together many percentage increases, and it also allows us to include percentage decreases as well. Note how 1.15 is basically the result of 100% + 15% = 1.00+0.15 = 1.15
Answer:
Step-by-step explanation:
<u>As per diagram we have:</u>
<u>As per 30° right triangle property:</u>
- CD = √3×CB/2 = 3√3 ≈ 5.2 cm
- and
- AC = 2CD = 2×5.2 = 10.4 cm
<u>Area of triangle:</u>
- A = 1/2bh
- A = 1/2CB*AC
- A = 1/2*5.2*10.4 ≈ 27 cm²
