Answer:
quantity a is halfed
Corrected question;
A quantity a varies inversely as a quantity b, if, when b changes a changes in the inverse ratio. What happens to the quantity a if the quantity b doubles?
Step-by-step explanation:
Analysing the question;
A quantity a varies inversely as a quantity b,
a ∝ 1/b
a = k/b ......1
when b changes a changes in the inverse ratio;
Since the change at the same ratio but inversely, k = 1
So, equation 1 becomes;
a = 1/b
If the quantity b doubles,
ab = 1
a1b1 = a2b2
When b doubles, b2 = 2b1
a1b1 = a2(2b1)
Making a2 the subject of formula;
a2 = a1b1/(2b1)
a2 = a1/2
Therefore, when b doubles, a will be divided by 2, that means a is halfed.
2^9 = 2 x 2 x2 x 2 x 2 x 2 x2 x 2 x 2 = 512
2 ^9 = 512
Answer:
I can't solve and show it but only tell a method to do it!
So find the zero of the given factor:
i.e.
Now put its value (-1) in the polynomial
Now if the answer comes zero it is a factor.
You'll get your answer!
Answer:
22
Step-by-step explanation:
484 = 2^2 × 11^2
√484 = 2×11 = 22
adding 320,294,265 and 301=1180
4 divided by 1180=answer 295
