Answer:
cm.
Step-by-step explanation:
We have been given that the average human body cell is about cm in diameter. The diameter of a plant cell is cm.
To find the combined diameter of the body cell and plant cell, we will add both diameters.
First of all let us convert our given diameters in standard notation.
Let us convert our answer in scientific notation.
Therefore, the combined diameter of the body cell and plant cell is cm.
Answer: x = 7
Step-by-step explanation:
8x - 2(4) = 48
2 * 4 = 8
8x - 8 = 48
+8 to each side
8x = 56
Divide each side by 8
x = 7
Answer:
The required y-value is -121.
Step-by-step explanation:
There are several ways in which we could approach this problem. From the two binomial factors (x + 8) and (x - 14), we know that the two roots are x = -8 and x = 14. The axis of symmetry is the vertical line x = 3. This value is halfway between x = -8 and x = 14.
Substituting x = 3 into f(x)= -(x+8)(x-14) results in f(3) = -(11)(-11) = -121.
The vertex is at (3, -121). The required y-value is -121.
Answer:
-4
Step-by-step explanation:
Absolute value is the distance from one number to the next, so it can't be negative. I-7+3I is 4.
- * 4 is equivalent to -1 * 5 so the answer is -4.
Answer:
That means it will take you 1 and 1/3 hour to go a kilometer.
