Answer:
iii. (l + m - n)(l - m + n)
vi. (5a -b) ( 5b - a)
Step-by-step explanation:
iii. l² - (m - n)²
= (l + m - n)(l - m + n)
vi. 4(a+b)² - 9(a-b)²
= (2(a+b))² - (3(a-b))²
= (2(a+b) + 3(a-b)) (2(a+b) - 3(a-b))
= (2a+2b + 3a - 3b) (2a+2b - 3a + 3b)
= (5a -b) ( 5b - a)
No.
So, there are 1000 milligrams in one gram, making the 4000 mgs equal to 4 grams.
There are 1000 grams in one kilogram, so 4 kilograms is equal to 4000 grams.
4000 =/= 4
So, 4 kilograms and 4000 milligrams are not equal.
Answer:
Resultant force will act on 65° N of W.
Step-by-step explanation:
As given in the question one bulldozer exerts force of 1250 pounds in western direction and 2650 pounds in northern direction and we have to find angle A which is an angle between 1250 pounds of force and resultant force F.
Therefore tan A= Force on North direction/ Force on west direction = 2650/1250 = 2.12
⇒
A = 64.75
A = 65° North of west.
It is 5:9 in simplest form
Answer:
a. y = 7500 - 500x
b. $ 4,500
Step-by-step explanation:
a. Given,
The original value of the phone = $ 75,00
Let the linear function that shows the value of booth after x years,
y = b - ax,
For x = 0 years, y = 7500
⇒ 7500 = b - a(0) ⇒ b = 7500
For x = 15, y = 0,
0 = b - 15x ⇒ 0 = 7500 - 15a ⇒ 15a = 7500 ⇒ a = 500
Hence, the function that shows the value of car after x years,
y = 7500 - 500x
b. if x = 6,
The value of the booth after 6 years would be,
y = 7500 - 500(6) = 7500 - 3000 = $ 4,500
