Answer:
The correct option is;
Reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down
Step-by-step explanation:
Answer:
h = 2A/b
Step-by-step explanation:
Step 1: Write out triangle formula
A = 1/2bh
Step 2: Multiply 2 on both sides to get rid of fraction
2A = bh
Step 3: Divide both sides by <em>b</em> to isolate <em>h</em>
2A/b = h
Step 4: Rearrange
h = 2A/b
Answer:
The one you picked is right! Good job!
This type of situation applies first order type of equation. In this case, the equation is ln( A0/A1) = kt. A is the number of bacteria cultured. A0 is equal to 150. when A1 is 300, t is 20 minutes. that is ln (150/300) = k *20 the other condition is represented by ln (A0/1200) = 60k. k is equal to -0.0347. hence the first order equation is equal to ln (150/A1) = -0.0347 t
Answer:
Step-by-step explanation:
Another way to solve would be to distribute first:
22 = 2(x + 6)
22 = 2x + 12
Subtract 12:
22 - 12 = 2x - 12
10 = 2x
Divide by 2:
10 / 2 = 2x / 2
5 = x
