Answer:
Step-by-step explanation:
Hello,
We can write the following, x being the second number.
Let's use the discriminant.
There are two solutions and the positive one is
So the solutions are 15 and 15*2-6 = 30-6 = 24
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
y = a(1 + r) ^v
y = 6200( 1 + 0.05)^v
y = 6200(1.05)^v
Step-by-step explanation:
Fred purchased a piece of artwork for 6200, and it is expected to increase in value by 5% per year. Write a function y to represent the value of the piece of artwork after v years.
The function we can used to represent the above question is given as Exponential Growth function.
Where the number of years = v
The value of the artwork = y
y = a(1 + r) ^v
Where
a = Initial value of the artwork = 6200
r = Growth rate = 5% = 0.05
v = number of years
Therefore, the function y to represent the value of the piece of artwork after v years is written as:
y = 6200( 1 + 0.05)^v
y = 6200(1.05)^v
Answer:
786 feet per min
Step-by-step explanation:
60 (mins in an hour) x 4= 240 mins
there are 5240 feet in a mile
5240 (feet in a mile) x 36= 188640
188640 divided by 240= 768
Answer:
1.5
Step-by-step explanation:
6/4=1.5
9/6=1.5
Mangoes = 4/9 x 180 = 80
Oranges = 5/9 x 180 = 100
Bananas = 3/9 x 180 = 60
Bananas:mangoes:oranges = 3:4:5 = 60:80:100
Total number of fruit = 60 + 80 + 100 = 240
