Answer:
D
Step-by-step explanation:
to find the value in grams, we just multiply by a 1000
so, 31.8 × 1000 = 31,800 grams
Answer:
The sum is
Step-by-step explanation:
Assuming we are finding the sum of :
3e + 7 - e and 2e + 10 + 2e -3
Then we set up the addition as follows:
We group similar try to get:
We now combine the similar terms to obtain:
Therefore the sum is
Evaporation I’m pretty sure
Answer:
The equation for a parabola with vertex at the origin and a directrix at x = 1/48 is .
Step-by-step explanation:
As directrix is a vertical line, the parabola must "horizontal" and increasing in the -x direction. Then, the standard equation for such geometric construction centered at (h, k) is:
Where:
, - Horizontal and vertical components of the location of vertex with respect to origin, dimensionless.
- Least distance of directrix with respect to vertex, dimensionless.
Since vertex is located at the origin and horizontal coordinate of the directrix, least distance of directrix is positive. That is:
Now, the equation for a parabola with vertex at the origin and a directrix at x = 1/48 is .
