The answer is A because completing the square gives a minimum of 2,-9 and factorising gives roots of 5 and -1 :)
Step-by-step explanation:
SI = P × R × T / 100
= 56780 × 3 × 3 / 100
= 5110.2
Answer:
D 40,000nm
Step-by-step explanation: 1nm/10^-9m * 10^-6/1um = 10^3 nm/um
Therefore in 40 microns there are:
40um * 10^3 nm/um = 40 * 10^3 nm = 40,000 nm
Answer:
XY = 11.25
Step-by-step explanation:
Corresponding sides of similar triangles are proportional.
XY/5 = 18/8
XY = 5(9/4) = 45/4
XY = 11.25
30,944 rounded to the nearest ten thousands would be 40,000. Where the 3 is located in the first number would be the 10 thousands place.
