Answer:
0.375%
Step-by-step explanation:
i=P*R*T
$360=$8000*R/100*18/12
$360=$960R
$360/$960=$960/960
0.375%=R

Answer:
4
Step-by-step explanation:
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
10 - 6 = 4
Lets take a look at the options first.
option 1 and option 4 are not possible as (8x) (8x) would give us 64x^2, which is not what we want.
we’re left with option 2 & 3. when expanded, option 2 will look like :
16x^2 - 40x - 10x + 25
= 16x^2 - 50x + 25
however, we do not want the 50x. so the answer is option 3, (4x-5) (4x+5)
if you don’t want to find the answer using expanding, there is also another method of expanding.
(a+b)^2 = a^2 - b^2
in this case, 16x^2 will be a^2 and 25 will be b^2. not sure whether you’ve learn this but yea.
