A1=8
common ratio=r
sum of 6 terms
S=a1+a2+a3+...+a6
=a1(1+r+r^2+...+r^5)
=a1(r^6-1)/(r-1)
but we're given S=74648
=>
8(r^6-1)/(r-1)=74648
Cross multiply and solve for r (by trial and error)
r^6-1=9331(r-1)
r=6
so
a(3)=a1*r^(3-1)
=8*(6^2)
=288
Ok but allow my humble self to use instead of .
We have,
If you wanna know what the inverse is swap the values of x and y,
And now solve for y,
.
Hope this helps.
Answer:
0.1875 (Put height unit)
Step-by-step explanation:
1/2 x 1/2 x 3/4 = 0.1875
Make sure to put ft3 of ft2 at the end or anything else
The two numbers that are distance 1.75 from 0 are the ones with absolute value 1.75.
_____
For many folks, the tricky part is figuring out where 1.75 is on this number line. Each tick mark represents a distance of 0.25 units, so 1.75 is at the tick mark between 1.5 and 2.0.
Answer:
-2
Step-by-step explanation:
y = mx + b
m = slope
Therefore m = -2
