Dave is correct you add the price of the 2 cups of coffee and piece of cake together 2.75+2.75+2.90= £8.40 then you subtract that from £10 so £10-£8.40= £1.60 which is more then £1.50
Sequence: -4, 8, -16
rate of increase: -16/8 = -2
If you make A1 the first term in the sequence you must use (n-1) in the explicit formula. If you go backwards in the sequence to find A0 = 2 then you would use n.
The don't have A0 = 2 listed as an option so we use A1 = -4 and (n-1) terms.
An = -4(-2)^(n-1)
Solving for the 5th term A5, use n = 5
A5 = -4(-2)^(5-1)
A5 = -4(16)
A5 = -64
So the answer is B.
Answer:
Option d
Step-by-step explanation:
Range of a function is the set of y-values for every x-values.
Domain is the set of all values of variable 'x'
From the picture attached,
y-values of the given function varies from negative infinity to positive infinity.
Therefore, range of the function graphed is a set of all real numbers.
Option d is the correct option.
Answer:
7 years 11 months
Step-by-step explanation:
The future value formula for the value of a principal P invested at annual rate r compounded n times yearly for t years is ...
FV = P(1 +r/n)^(nt)
For the given numbers, we want to find t:
6000 = 3700(1 +.062/2)^(2t)
Dividing by 3700 and taking the logarithm, we get ...
6000/3700 = 1.031^(2t)
log(60/37) = 2t·log(1.031)
Dividing by the coefficient of t gives ...
t = log(60/37)/(2log(1.031)) ≈ 7.92 . . . . . years
It will take about 7 years 11 months for the investment to grow to $6000.
X = integer one
y = integer 2
x = 12y + 4
x * y = 5896
Solve the system of equations
