Answer:
62 Kg
Step-by-step explanation:
Let g = weight of Grok last year in kg
m = weight of Grok's mother last year in kg
m = 3g
m-4 = 2(g+9)
since m = 3g
(3g)-4 = 2(g+9)
3g -4 = 2g + 18
3g-2g = 18+4
g = 22
m = 3*22
= 66
Note that:
g+9 = weight of Grok now
m-4 = weight of Grok's mother now
Grok weighs 31 Kg now
Grok's mother weighs 62 Kg now
Answer:
A = 50x^2+3
B = 75
C = 55
Step-by-step explanation:
A. f(g(x))
B. g(g(3))
C. g(f(-2))
Answer:
f(x) = 4(1.02)^(7x); spreads at a rate of approximately 2% daily
Step-by-step explanation:
The weekly number of people infected is:
f(x) = 4(1.15)^x
So the daily number of people infected is:
f(x) = 4(1+r)^(7x)
To find the value of the daily rate r, we set this equal to the first equation.
4(1.15)^x = 4(1+r)^(7x)
(1.15)^x = (1+r)^(7x)
(1.15)^x = ((1+r)^7)^x
1.15 = (1+r)^7
1.02 = 1+r
r = 0.02
So the equation is f(x) = 4(1.02)^(7x), and the daily rate is approximately 2%.
Answer:
it could be and to show his number two because it's running all those numbers up over and over again by percentage is that the end is going to give you a big number
Step-by-step explanation:
on the beginning is adding 200 + 50 we should give you 250 then is a 200 more so it was equals to 450 but then he asked you per week you get 50 extra so is basically 50 x 6 cylinder 6 weeks and I will give you a promise off $300 $300 + 450 equals to 750 each week is 10% so is basically equals to 50 so 50 + 50 + 50 + 50 or the easiest way is 50 * 6 I would go with answer to like I said because it's showing like a little of of a conversation was not given in any Solution on a specific number and that's the most closest one to like the whole problem
