Answer:
The longer leg is opposite the 60, so to get the shorter leg you have to divide by \sqrt{3}
18 / \sqrt{3} = 6 \sqrt{3}
Answer:
y= −9.16x²+73.04x+183.3
Values increase till x = 4 and then decrease which means thus curve has a maximum turning point around 4.
Coefficient of x² should be negative
because max to (concave down)
x = -b/2a should be around 4
x = -73.04/(2×-9.16) = 3.987
The infinite geometric series is converges if |r| < 1.
We have r=1/6 < 1, therefore our infinite geometric series is converges.
The sum S of an infinite geometric series with |r| < 1 is given by the formula :
We have:
substitute:
Answer: d. Converges, 504.
Let's assume there are 52 weeks in a year,
so we have , rate= 6.4/52= 0.123%
now ,
c.i = 5000[(1+0.123/100)^3×52 -1]
= $1056.911
took me a while
Well, basically there are
acute angle, right angle, obtuse angle ..
and also we use concurrent angles, corresponding angles, alternate angles, vertically opposite angles,..
..hope it helped a bit
