Hey there!
Answer-
See Below.
Step by step explanation-
Let the number of 50 paise coins be x, then the number of 25 paise coins will be 4x.
The value of 50 paise coins is 50x paise and the value of 25 paise coins be 25(4x)=100x paise.
According to the giving condition,
∴The number of 50 paise coins is 40 and number of 25 paise coins is 4x=4(40)=160.
Answer: -3, -5, -7 from top to bottom
Step-by-step explanation:
just plug in the x to the function f(x)=-x
which mean f(x)=-3, f(x)=-5, f(x)=-7
1st box: 2a (subtract 2a from both sides)
2nd box: 3 (add 3 to both sides)
3rd box: 10 (add 7+3)
4th and 5th box: 2 (divide both by 2)
6th box: 5 (10/2=5)
Answer:
The function is
Step-by-step explanation:
The table representing balance in the account is presented as follows;
Year t
0 100
1 125
2 156.25
3 195.31
4 244.14
5 305.18
The given exponential relationship is y = a·b^t
When t = 0, y = 100
We get; 100 = a·b⁰ = a·1
∴ a = 100
When t = 1, y = 125
We get;
125 = 100·b¹
∴ b = 125/100 = 1.25
The function that represent 'y' (in dollars) after 't' years is y = 100×1.25^t
