Answer:
There is none
Step-by-step explanation:
You've been bamboozled. It isn't a function if the same x-value has 2 different y-values.
There is no equation to your line
Answer:
Step-by-step explanation:
Cost of stock (without the broker's fee) : 3000 * 6.30 = 18,900
Cost of broker's fee: 3000 * 0.02 = $ 60
For a total cost of (18,900 + 60) = $18,960
The unknowns : number of boys (b) and number of girls (g)
b + g = 23
g = b + 7
b + b + 7 = 23
2b + 7 = 23
2b = 23 - 7
2b = 16
b = 16/2
b = 8 <=== there are 8 boys
g = b + 7
g = 8 + 7
g = 15 <=== there are 15 girls
The formula for a geometric sequence is an = a1 * r^n-1. For this problem, our formula can be an = 1 * 5^n-1. a1 is our first term, and r is the common ratio.
To check our formula, we can find the 5th term. a5 = 1 * 5^5-1. This gives us 625. If we look at our last term provided, the 4th term, 125 * 5 is 625.
Step-by-step explanation:
It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full rotation.. We are going to write the time not in days, hours and minutes, but only hours. This means that we have to write 58 days as hours and 30 minutes as hours. 1 day is 24 hours, so 58 days are 58*24=(50+8)*(20+4)=50*20+50*4+8*20+8*4=1,000+200+160+32 =1,200+192=1,392 (hours) 60 minutes are 1 hour, so 30 minutes are 0.5 hours. Thus 58 days, 15 h, and 30 min are (1,392+15+0.5) hours = 1,407.5 hours Answer: 1,407.5 hours
