An exponential equation is represented through the equation;
y=abˣ
Here, a represents the starting value/point and
b represents the number by which the equation exponentially increases/decreases by.
In the given situation, a would be represented by the number $400,000.
Hope I helped :)
Answer:
The indifference point is 2.1 hours.
Step-by-step explanation:
<u>First, we need to calculate the total cost for each option:</u>
<u />
Dealership:
Total cost= 24 + 99x
Local mechanic:
Total cost= 45 + 89x
x= number of hours
<u>Now, we need to equal both formulas and isolate x:</u>
24 + 99x = 45 + 89x
10x = 21
x= 2.1
The indifference point is 2.1 hours.
<u>Prove:</u>
Total cost= 24 + 99*2.1= $231.9
Total cost= 45 + 89*2.1= $231.9
Answer:
-40
Step-by-step explanation:
This is because she LOST 40 dimes making it a negative number, so the integer to represent this would be -40.
PLEASE, forgive me but I answered this and hopefully what I see is correct. I’m really sorry if this weren’t the real measurements!
Answer:
192 square inches
Step-by-step explanation:
Surface area questions often include the net for easy answering. All you do is just find the area of each face and add them all up:
As you can see, all triangles in this net of a pyramid are the same, so once we find the area of one triangle, we’ll just multiply by 4:
FIND AREA OF ONE TRIANGLE (1/2 x b x h)
1/2 x 8 x 12 = 48 square inches
MULTIPLY BY 4 for SURFACE AREA:
48 x 4 = 192
so the SA is 192 square inches!
