For 5, we if the y-vlaues are increasing by a common ratio.
(y at x = 1) / (y at x = 0) is = 8 / 4 = 2
(y at x = 2) / (y at x = 1) is 24 / 8 = 3
(y at x = 3) / (y at x = 2) is 48/24 = 2
no, exponential function cannot model this data. you can see that the what you have to multiply to the previous changes.
exponential function has the form y = a(b)^x. if that "b" value kept changing, it's not exponential. like y = 4(2)^x would be exponential only for the first two values since y = 4(2)^x at x = 0 is 4 and y = 4(2)^x at x = 1 is 8, but it is not 24 at x = 2 since y = 4(2)^2 = 16.
6.
exponential function has the form y = a(b)^(x)
we see at x = 0, y = 1 so
1 = a(b)^0
1 = a(1)
a = 1
since a=1, we have y = 1(b)^x. to find b, use other points
since at x = 1 we have y = 3, then
3 = (b)^1
b = 3
so the function is y = 3^x
The model that shows the break even point is that which shows that cost is equal to revenue.
10 + 30h = 5h² - 25
The vaue of h is equal to 7. Thus, Alan can only breakeven after 7 hours of working in in the television repair shop.
Answer:
The triangle ABE and DCE are congruent because they are the same size and same shape meaning they are congruent.
Step-by-step explanation:
For two figures to be congruent they must be the same size and shape or one could mirror the other since they mirror each other and are the same size and shape they are congruent.
Disclaimer- this is all assuming that "semi monthly" means twice a month. if it doesn't, ignore this answer
A- if semi monthly is half a month, then 4 times 2 is 8, and 8 times 12 is 96,000.
B- If there are 4 weeks in a month and 4000$ accounts for half of that pay, then the weekly pay is 2000, making the bi-weekly pay 1000.
C- The monthly pay is 8,000$ because 4,000 x 2 is 8,000
D- The weekly pay is 2,000$ because the monthly pay is 8,000$ and there are 4 weeks in a month
E- I do not know the hours at this job and therefore cannot answer this
It is 5! Hope I can help! :)
