The missing justification in the proof is
<span>B) Substitution property of equality
The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.
Step-by-step explanation:
Given diameter of table (circular) =1.6m
radius =0.8m
area of circle = πr
2
=3.14×0.64=2.0096m
2
Now rate of polishing per meter square =15Rs
Cost of polishing table top = 15×2.0096
cost = 30.14m
2
So Boris has to pay:
10% * 8190 = 819
50% * 662 = 331
50% * 188 = 94
so in total he pays: 819 + 331 + 94 = 1244
deducted each week is (52 weeks in a year):
1244/52 = 23.92
so each week $23.92 are deducted from his paycheck
Answer:
Answer is B
The equation is correct since(log2^10)(log4^8)(log10^4)=log10/log2*log8/log4*log4/log10
=log8/log2
=3
Step-by-step explanation:
The graph is the one that correctly represents the linear piece-wise function is the first graph.
<h3>How to solve for the graph</h3>
First we have a linear function as
Mx + b
mc= slope, this is the rate of change, how y changes as x changes by 1.
b = y-intercept, y value as x = 0
y = 5 + x
x ≤ 10
at 10 we have 5 + 10 = 15
at 2 dollars
y = 15 + 2(x - 10)
at 14
y = 15 + 2(14 - 10)
15 + 2*4
= 23
Hence we can conclude that the first graph here is the correct one.
