Answer:
A
Step-by-step explanation:
Given
p² - 16 = 0 ( add 16 to both sides )
p² = 16 ( take the square root of both sides )
p = ± 
= ± 4
Thus solution is { - 4, 4 } → A
I think the answer is B? They didn't say whether point P is in the centre of the circle, so the answer could also actually be D. But assuming that P is the centre point of the circle, the answer should be B.
AP (7mm) > Radius of circle p (6mm)
meaning that the line should extend out of the circle from the centre of it and thus produce one intersection.
As for the rest of the line, BP,
BP (3mm) < Radius of circle p (6mm)
meaning that if the distance of point P to point B is shorter than the distance of point p from the line of the circle (this distance being the radius), it should not make another intersection.
Therefore, there is only 1 intersection and the answer should be B (if point P is the middle of circle p)
Answer:
B
Step-by-step explanation:
thy get 55/75 and you want to know x/300
55/75 x X/300
cross multiply 55 x 300 = 16500
divide that by 75
16500/75 = 220
x = 220
they will get $220
Answer:
less
Step-by-step explanation:
We assume price of a shirt is $100.
Initially price is <u>increased</u> by 10%: 100+10=110
Then it is <u>reduced</u> by 10%: 110-11=99
Now price of a shirt is $99.
Answer is price of a shirt is less than it was at the start.
