This problem represents a geometric sequence. Which is always:
a(n)=ar^n where a is the original term, r is the common ratio, and n is the number of terms.
In this case, we wish to know the minimum common ratio which will produce 750000 for the 7th term given that the first term a is you, one :) so we have the equation...
a(n)=r^n using 750000 for a(7) and 7 for n...
750000=r^7 taking the natural log of both sides...
ln(750000)=7(lnr)
lnr=ln(750000)/7
r=e^(ln(750000)/7)
r=6.91 since r must be an integer for this particular problem r=7
So our equation was:
a(7)=7^7=823543
note if we only shared with 6 originally you would fall very short...
a(6)=6^7=279936
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i
Leave a comment if you have a correction.
AOD = 180 - (90+32) = 58 because when a tangent meets a radius they form a right angle
ABC = 1/2 AOD = 29 because it's subtended by the same ark as the AOD and O is center of the circle
Company C has the best deal out of all of these options, as each hoodie costs $2.74 from Comoany C
Answer:
hope that helps i don't know it either tho
