Answer:390
Step-by-step explanation:
so each means multiply so 3 1/2 X 2, then 4 X 4, 4 1/2 X 3 then 5 X 1 lastly add them up
765° = 45°
1485° = 45°
We get 2sin(45°) + tan(45°) + cot(135)
sin(45) = sqrt(2)/2
tan(45) = 1
cot(135) = -1
we get
2*[sqrt(2)/2)] + (1) + (-1)
= sqrt(2)
Answer: The multiplicative inverse of – 1 in the set {-1,1} is<u> -1</u>.
Step-by-step explanation:
In algebra, the multiplicative inverse of a number(x) is a number (say y) such that
[product of a number and its inverse =1]
if x= -1, then
That means , the multiplicative inverse of -1 is -1 itself.
Hence, the multiplicative inverse of – 1 in the set {-1,1} is<u> -1</u>.
Answer: You would swap the ineqaulity
Step-by-step explanation:
Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true.
