Answer:
a) 1/800 or 0.00125
b) i) 0.0013
ii) 0.001
c) 60%
Step-by-step explanation:
T = [tan(2×30)+1][2cos(30)-1] ÷ (y²-x²)
T = (tan60 + 1)(2cos30 - 1) ÷ (41² - 9²)
T = (sqrt(3) + 1)(sqrt(3) - 1) ÷ 1600
T = (3-1)/1600
T = 2/1600
T = 1/800
T = 0.00125
Error: 0.002 - 0.00125
0.00075
%error
0.00075/0.00125 × 100
60%
Answer:

Step-by-step explanation:
50.441-6.203=44.238
Answer:
The only correct answer is:
All positive numbers have two square roots
Step-by-step explanation:
This is true because in any situation all positive numbers have two square roots. For example, the square root of 25 is +/- 5 which means that 5 is a square root (because 5x5=25) and -5 is a square root (because -5x-5=25).
The others such as 18 = 9, 149 = 7, and 25 = 5 are all false statements.
Answer:
y=-8
Step-by-step explanation:
Let's solve your equation step-by-step.
15y−4=12y−28
Step 1: Subtract 12y from both sides.
15y−4−12y=12y−28−12y
3y−4=−28
Step 2: Add 4 to both sides.
3y−4+4=−28+4
3y=−24
Step 3: Divide both sides by 3.
3y
3
=
−24
3
y=−8
