Answer:
It´s A
Step-by-step explanation:
You can eliminate B and D because the ¨x¨ would be 4 not 80 because it´s on the x-axis not on the y-axis. Secondly whenever you have a graph you need to have the less than or equal to sign with the line under.
Hope this helps :)
-17 .. on a number line from right to left -5 is closest to zero, making it bigger than -17
The rate of 28,000% per month is extremely big. I believe
the correct monthly rate is 2.8% (correct me if I am wrong though). Next time
kindly check the given values.
Rate is expressed in a factor of:
(1 + r)^n
where r is the rate and n is the number of months
First we calculate for the rate in a year (1 year = 12
months). We know that the rate must be constant, therefore:
rate in a month = rate in a year
(1 + 0.028)^1 = (1 + r)^(1/12)
r = 0.3929
Therefore there is an increase of about 39.29% in a year.
Then we calculate for the rate in a day (1 month = 30
days). The rate must also be constant, therefore:
rate in a month = rate in a day
(1 + 0.028)^1 = (1 + r)^(30)
r = 9.21 * 10^-4
Therefore there is an increase of about 0.092% per day.
Answer:
r = 4
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
V = 100.48
h = 6
π = 3.14
Work:
V = πr²(h/3)
100.48 = r²(3.14)(6/3)
100.48 = r²(3.14)(2)
100.48 = r²6.28
r² = 100.48/6.28
r² = 16
r = 4
