Answer:
The 8th term is 23
Step-by-step explanation:
If we are given the formula for the sequence
an=2n+7,
then to find the 8th term we substitute n=8 into the formula.
a8 = 2(8) +7
a8 = 16+7
a8 = 23
The 8th term is 23
Answer:
Step-by-step explanation:
Part A. John will not be painting the floor area of that of the door or window openings.
Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.
Part C.
We first need to find the area to be painted.
A=floor+2(wall1)+2(wall2)-window-door
A=14(7)+2(7)8+2(14)8-3(6)-3(7)
A=98+112+224-18-21
A=395 ft^2
Since a gallon of paint will cover 350 ft^2
395ft^2(gal/350ft^2)=1.13 gal
John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)
f(x) = (x + 7)² - 8
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
given the quadratic in standard form : y = ax² + bx + c ( a ≠ 0 )
then the x-coordinate of the vertex is
= - 
f(x) = x² + 14x + 41 is in standard form
with a = 1, b = 14 and c = 41
= - 
= - 7
substitute this value into the equation for y- coordinate
y = (- 7 )² + 14(- 7 ) + 41 = 49 - 98 + 41 = - 8
f(x) = (x + 7)² - 8 ← in vertex form
