Answer:
New Formula is ![N(t) = 30t](https://tex.z-dn.net/?f=%20N%28t%29%20%3D%2030t%20)
You should expect 90 cells
Step-by-step explanation:
✔️The new formula that would represent the number of cells when 30 isolated cells are used to start a culture would be:
![N(t) = 30t](https://tex.z-dn.net/?f=%20N%28t%29%20%3D%2030t%20)
✔️Number of cells, N(t), to expect after 3 hours, t:
Substitute t = 3 into ![N(t) = 30t](https://tex.z-dn.net/?f=%20N%28t%29%20%3D%2030t%20)
Thus:
![N(30) = 30*3](https://tex.z-dn.net/?f=%20N%2830%29%20%3D%2030%2A3%20)
![N(30) = 90](https://tex.z-dn.net/?f=%20N%2830%29%20%3D%2090%20)
You should expect 90 cells

Answer:
A
Step-by-step explanation:
THe perimeter is the sum of all the sides.
A triangle has 3 sides and we sum up the expressions to find the expression for perimeter.
Lets do this:
![(6.2p + 4.5q)+(3.4p-0.7r)+(2.9r-4.1q)\\=(6.2p+3.4p)+(4.5q-4.1q)+(-0.7r+2.9r)\\=9.6p+0.4q+2.2r](https://tex.z-dn.net/?f=%286.2p%20%2B%204.5q%29%2B%283.4p-0.7r%29%2B%282.9r-4.1q%29%5C%5C%3D%286.2p%2B3.4p%29%2B%284.5q-4.1q%29%2B%28-0.7r%2B2.9r%29%5C%5C%3D9.6p%2B0.4q%2B2.2r)
We have added "p"s and "q"s and "r"s, together.
THe answer is Option A
Answer:
Of all 6 faces it would be 150
Step-by-step explanation:
If one side of the cube is 5cm long, then l × w = area of a face, so if it is a cube then all 4 sides are the same on a face so 5 × 5 = 25, so 25 × 6 faces = 150
Y + 2 > - 3x - 3
y > -3x - 3 - 2
y > -3x - 5
ur line will be dashed (because there is no equal sign in ur problem)...so that eliminates A and C
ur y int (where the line crosses the y axis) is at (0,-5)...the x int (where the line crosses the x axis) is at (5/3,0)...ur slope is -3
shading will occur above the line
ur graph is : graph D
