Answer:
vertex = (- 7, - 87)
Step-by-step explanation:
given a parabola in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
p² + 14p - 38 is in standard form
with a = 1, b = 14, c = - 38, hence
= - 
= -7
substitute x = - 7 into the equation for corresponding value of y
y = (- 7)² + 14(- 7) - 38 = 49 - 98 - 38 - - 87
vertex = (- 7, - 87)
Answer:
y = 8x + 15
Step-by-step explanation:
Step 1: Find slope of perpendicular line
<em>Take the negative reciprocal of the 1st equation</em>
m = 8
y = 8x + b
Step 2: Find <em>b</em>
7 = 8(-1) + b
7 = -8 + b
b = 15
Step 3: Rewrite perpendicular equation
y = 8x + 15
Answer:
460 in.^2
Step-by-step explanation:
Using the formula provided in the image: <em>SA = 2lw + 2lh + 2wh</em>
Length = 10 in.
Height = 12 in.
Width = 5 in.
2(10 * 5) + 2(10 * 12) + 2(5 * 12) = 100 + 240 + 120 = 460
Answer:
7/2 x 52/3
Step-by-step explanation:
Steps:
Since 1 year = 52 weeks
52*7/2*3= 7/2*52/3
Since 1 year equal 52 weeks meaning we have to times 52 by 7/2 then times by 3 the weeks. The answer is below.
Answer: 7/2 x 52/3
