You're welcome :)
Answer:
y = 4 * (7/4) ^x
Step-by-step explanation:
y = ab^x is the general form of an exponential function
where a is the initial value and b is the growth rate
We know 2 points, (0,4) or the initial value and (1,7)
a =4
y = 4 b^x
7 = 4 b^1
We can solve for b
Divide by 4
7/4 = b
y = 4 * (7/4) ^x
He will earn £360, for a total in his account of £1560.
The formula for simple interest is
I = prt, where I is the amount of interest, p is the principal invested or borrowed, r is the rate as a decimal number, and t is the amount of time. Using our information we have:
I = 1200(0.1)(3) = 360
This is the amount of interest. We add this to his original 1200 to get the total amount:
1200 + 360 = 1560.
Answer:
52/ 10 = 5 2/10 or 5 1/5
Step-by-step explanation:
first turn the mixed fractions into improper fraction
13 1/10= 131/10
7 9/10= 79/10
since the two fractions already have a common denominator just subtract
131 - 79 = 52
52/ 10 = 5 2/10 or 5 1/5
