Answer: 681 square inch
Step-by-step explanation:
Hi, we have to apply the formula for the surface area:
A = 2wl + 2lh + 2hw
Where:
w: width
l: length
h: height
Replacing with the values given:
A = (2x12x18.25) + (2x12x3)+(2x18.25x3)
A= 438+72+109.25
A=619.5 in2
Since it has to be 10% more than the surface.
619.5 x (10/100) = 61.95 in2
Adding that value to the surface area
619.5+61.95 = 681.45in2 = 681 in2
We see it is the y terms squared so it opens left or right
in form
(y-k)^2=4(p)(x-h)
vertex is (h,k)
and p is distance from focus to vertex, also distance from vertex to directix
if p>0, then it opens to the right and dirextix is to the left of vertex
if p<0, then it opens to the left and directix is tothe right of vertex
so
(y-1)^2=4(4)(x-(-3))
vertex is (-3,1)
4>0 so dirextix is to left of vertex
left is in x direction
-3-4=-7
directix is x=-7
Answer:A)54 farms
B) 16 farms
Step-by-step explanation:
Y(1200) = (1200-1400)/100 = -200/100
Y(1200) = -2
Y(1600) = 1600-1400)/100
Y(1600) = 200/100 = 2
P(1200-1600) = (2y<-2)
2 standard deviation from the range = 68%=0.68
80 farms × 0.68 = 54 .4 approximately 54
B) 24× 0.68= 16.32 approximately 16
Answer:
Step-by-step explanation:
Answer:
y= -3/8x + 1
Step-by-step explanation:
-4 = x1
5 = y1
y-y1=m(x-x1)
y-5 = -3/8(x-(-4)
y-5 = -3/8x + -3/2
+5 +5
y= -3/8x + 1
