Hey there :)
0.043
The first 0 before the decimal point is not significant since it is used for cosmetic purpose
The 0 after the decimal is not significant as the 0 is used to locate the decimal point
The 4 is the first nonzero integer and it counts as a significant figure
Therefore, 0.04 will be your answer rounded to 1 s.f
You have to divide 4 by 8 which = .5 and then u put the whole # before the decimal which will equal 4.5 , therefore knowing that 5 divided by 8 =0.625 does not help u write the decimal for 4 4/8 but the decimal for 4 4/8 is 4.5
Method 1.
Use the formula of a distance between two points:
We have
substitute
Answer: 10
Method 2
Look at the picture.
Use the Pythagorean theorem:
Answer: 10
The answer would be 6.00^3.
Remember that .21 < .50
Answer:
tanθ = -1
m=tanθ = -1
Step-by-step explanation:
Step 1:-
using formula m=tanθ
Given straight line is x+y=0
The given straight line is passing through the origin so y = -x
straight line is passing through the origin so y = m x
m = -1
Step3:-
The line with equation x+y=0 with the terminal side of an angle θ in standard position in Quadrant II i.e., θ = 90+45=135
m = tanθ
m = tan(90+45)
m = - cot 45
m = -1
Step4:- m =tanθ =-1
