Answer below
Step-by-step explanation:
Yo uneed to find the Area/volume
The area of the rectangle is 2×(5cm×1cm)+2(3cm×1cm)+2(5cm×3cm)=10cm+6cm+30cm=36cm^2
Volume=5cm×3cm×1cm=15cm^3
Ratio: 36cm^2/15cm^3=12cm^2/5cm^3
Answer:
The First Image
Step-by-step explanation:
A dilation is a type of transformation that enlarges or reduces a figure, therefore in the first Image we see an increase in scale factor of 2.
Answer:
y + 2 = -4/5 (x - 3)
Step-by-step explanation:
y - y1 = m (x - x1). Put in your points for y1 and x1, and always remember to flip your signs.
unfortunately, I don't know why that isn't one of your answers, so sticking with the positive 2 I would choose y+2=- (- 3) if I were you. Looks like the -4/5 disappeared somehow?
Hope this helps
Step-by-step explanation:
Rate of growth equals 420/100 = 4.2 times per hour
So after t=three hours,
size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,
round to nearest unit 7409 bacteria after three hours (after initial size of 100).
