Answer:
Plan B
Step-by-step explanation:
Let's calculate the amount required for each plan
<h3>Plan A</h3>
- 0.15*200 + 0.10*100 = $40
<h3>Plan B</h3>
- 15 + 200*0.05 + 100*0.05 = $30
As we see Plan B costs less
Answer:
w=15
Step-by-step explanation:
-24=-3w+21
We move all terms to the left:
-24-(-3w+21)=0
We get rid of parentheses
3w-21-24=0
We add all the numbers together, and all the variables
3w-45=0
We move all terms containing w to the left, all other terms to the right
3w=45
w=45/3
w=15

Answer:
Step-by-step explanation:
in this case we have a right angled triangle, whenever you see this triangle think of the TRIG RATIOS * sin, cos & tan* but if it was another triangle besides right angled triangle you use SINE RULE OR COSINE RULE
SOLUTION
Answer:
C. Directrix and Focus
Step-by-step explanation:
Given choices are :
A. Locus and Directrix
B. Axis and vertex
C. Directrix and Focus or
D. Vertex and Locus
Now we need to find about which of the above choices are the exact same distance from a parabola.
By definition of parabola, vertex lies at equal distance from directrix and focus.
Hence choice C. Directrix and Focus is correct.
