Answer:

Step-by-step explanation:
We know that for principal amount P , time period T and rate of interest
, simple interest is given by
.
Here ,

To find : simple interest rate i.e., 
On putting values of
in formula , we get 

Now we need to round off the answer to the nearest tenth .
So, simple interest rate is % =
=
Answer:
+120/169 or -120/169
Step-by-step explanation:
- let
![cos^{-1}[\frac{5}{13} ] = \alpha](https://tex.z-dn.net/?f=cos%5E%7B-1%7D%5B%5Cfrac%7B5%7D%7B13%7D%20%20%5D%20%3D%20%5Calpha)
where, alpha is some angle that satisfies the assumed condition.
- so,

[ taking cos to the other side or applying cos on both sides]
- now, substitute this in the given expression
as sin
= 
[by general trigonometry formula:
]
so if
, we can get sin
from the above formula as + or - 12/13
(because, after taking square root on both sides we keep + or -]
- as, sin
![2\beta = 2*sin[\beta ]*cos[\beta ]](https://tex.z-dn.net/?f=2%5Cbeta%20%20%3D%202%2Asin%5B%5Cbeta%20%5D%2Acos%5B%5Cbeta%20%5D)
[by general trigonometry formula]
- here, now
![sin[2\alpha ]=2*(+or- 12/13)*5/13\\](https://tex.z-dn.net/?f=sin%5B2%5Calpha%20%5D%3D2%2A%28%2Bor-%2012%2F13%29%2A5%2F13%5C%5C)
so, the final value can be 120/169 or -120/169.
Reciprocal
1/6 turns into 6/1 which is 6
Probably a circle. Its the same thing as cutting a cube and getting a square, and cross sectioning a pentagonal prism and getting a pentagon.
Answer:
Slope is -4
Step-by-step explanation:
y-7=-4(x+8)
y=-4(x+8)+7
y=-4x-32+7
y=-4x-25
