The interior angle of a regular polygon is equal to each other since all sides of the polygon are congruent. The formula that expresses the relation of the sides of the polygon and the measurement of the interior angle is (n2)*180/n where n is 7. Each interior angle then measures 128.6 degrees.
Hello :
y = 3x²+9x
= 3(x² + 3x )
= 3 ( x² +2(3/2)x +(3/2)²) -(3/2)²)
= 3((x+3/2)² -9/4)
y = 3 (x+3/2)² -27/4
<span>the x-coordinate of the vertex is : - 3/2</span>
Answer:
11
Step-by-step explanation:
Since both points have the same x value, we know they are vertical to each other.
One point is 4 units above the x axis, the other is 7 below the x axis.
4 + 7 = 11
the equation goes like this
y = ab^x
y = total cost
a = the intital amount (in your case the $1700)
b = the interest (since this is an exponetial growth it should be 1.013)
x = time
soo y = 1700(1.013)^x is the equation
