Answer:

y=4sin(\frac{10\pi}{7}x)+5

Step-by-step explanation:

<u>Recall formula</u>

y=asin(bx+c)+d\\\\y=4sin(bx)+5

<u>Determine b from period</u>

\frac{2\pi}{b}=\frac{7}{5}\\ \\ 10\pi=7b\\\\b=\frac{10\pi}{7}

<u>Final Equation</u>

y=4sin(\frac{10\pi}{7}x)+5

What is the coefficient of the term of degree 9 in the polynomial below? 5+7x9+12x-5x7+3x2
OlgaM077 [116]
Given a polynomial functin
ax^2+bx+c, the highest degree is 2
given another polynomial say ax^3+bx^2+cx+d, the degree of the polynomial is 3.
 From the above we can conclude that the degree of a polynomial is its highest power. 
From the function given:
5+7x^9+12x-5x^7+3x^2

The highest power is 9, thus it is a polynomial of degree 9. 

The coefficient of the term of degree 9 is 7.

The answer is 7.

What is algebra 1 and 2
telo118 [61]
Algebra 1 is a basic algebra course usually taken in freshman year (9th grade). Common Core guidelines dominate the curriculum. It is faster paced than middle school math courses. Algebra 2 is a more advanced algebra course usually taken in junior year (11th grade). Algebra 2 is paced even faster and builds on what you learn in A1 and geometry. Both deal with variables and the manipulation of numbers.
