Answer:
Step-by-step explanation:
the polynomial function is; (x - i)(x-2)(x+2)
Answer:
The radius is 1
Step-by-step explanation:
The acceptable length of the rod that has the standard length of 30.5 cm and can only from the ideal length by at most 0.015 cm is from 30.485 cm to 30.515 cm. This is computed by deducting and adding 0.015 cm to the standard length.
You can create equations to find the lengths and how they compare.
The line is in order of A-B-C-D
Both ratios share BC so we can use that to transfer from one ratio to the next.
AB =3x AC=7x
subtract them to find the measurement of BC
AC- AB = BC
7x-3x = 4x . BC = 4x
BD= 9y CD=2y
Subtract them to find the measurement of BC
BD - CD = BC
9y-2y =7y BC =7y
CD is 100cm so 2y= 100 or y=50
substitute y for bc
7(50)=350
substitute BC for terms of x
350 = 4x
divide both sides by 4
X= 87.5
Substitute for AB
AB = 3x
AB = 3(87.5) = 262.5cm
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
If your answer is a negative number then this is a percentage increase.
Thus, the answer is a 86.7% (rounded) increase.
