Answer:
function
Step-by-step explanation:
A <u>function</u> is a rule that pairs each element in one set with exactly one element from a second set.
A function for which every element of the range of the function corresponds to exactly one element of the domain. One-to-one is often written 1-1. Note: y = f(x) is a function if it passes the vertical line test.
9) 0.31
10) (7x10^6)-(3x10^3)
7000000-3000=6997000
6.997x10^6
Hope this helps :)
Steps:
1. Do a proportion
8000 pounds/4 tons= 7000 pounds/ x
2. Do 7,000 times 4 which equals 28,000
3. Do 28,000 divided by 8,000
4. Your answer is
3.5 tons
Answer:
first option
Step-by-step explanation:
Multiplying a complex number by its conjugate gives a real number and thus removes imaginary numbers in the denominator.
If z = a + bi then its conjugate is a - bi and their product
(a + bi)(a - bi) → where a and b are real
= a² + b² ← a real number
