Your answer is (a) because 4 times 2 is 8 but since it's negative 2 it's negative 8
The law of cosines for this particular situation is b^2 = a^2 + c^2 - 2ac cosB.
Filling in what you know, you have b^2 = 25 + 49 - [2(5)(7)-.1908], which simplifies to b^2 = 74 - 69.8092 which gives you a b^2 value of 4.1908, but you have to take the square root of that so you get a side value for b of 2.05.
Answer:
1. 425,328 -> 425,330
2. 105,025 -> 105,030
3. 45,527 -> 45,530
4. 35,478 -> 35,480
5. 212,369 -> 212,370
Step-by-step explanation:
000,0<u>0</u>0 the underlined number is the tens place. In order for the tens place to round up the ones place must be 5 or above. If the ones place is lower than 5 you round down to the nearest tens.
In Example:
333,389 you would round up to 333,390 because of the 9 in the ones place.
Now, 333,333 you would round down to 333,330 because of the 3 in the ones place
I think it’s D.y2 +xy+x+3y+2
(Sorry if I’m wrong)
A = 0.366666 ... = 0.3(6)
10a = 3.(6)
100 a = 36.(6)
100a - 10a = 36.(6) - 3.(6)
90a = 33
a=33/90=11/30
oh wait lol i didnt notice it was from 2017
