Two Petri dishes were on the desktop in Dr. McFarlan's lab.

Dish A had cells with a radius of 3.4 × 10^-13 cm. Dish B had cells that had a radius of 4.6 × 10^-11 cm. What is the sum of the radii of the two types of cells, using scientific notation?

A.

4.634 × 10^-15 cm

B.

46.34 × 10^-14 cm

C.

463.4 × 10^-13 cm

D.

4.634 × 10^-11 cm

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
