You can determine sinθ by looking at the y-axis and θ by looking at the x-axis.

θ = 90°, sinθ = 1
θ = 180°, sinθ = 0
θ = 270°, sinθ = -1
θ = 360°, sinθ = 0

Answer:

Step-by-step explanation:

We can clearly see the values of sin x at the vertical axis that is y-axis because the function is

y= sin x

\theta will be at x place and the entire will be y

Hence, look at y-axis to get the value of sin x

sin0^{\circ}=0

sin90^{\circ}=1

sin180^{\circ}=0

sin270^{\circ}=-1

sin360^{\circ}=0

Since, The range of sinx is [-1,1] value will fluctuate between this interval only.

the formula y-y1 =m(x-x1) is the pot slope form of the equation of a line where m is the slope of the line and(x,y) and (x1,y1)
oksano4ka [1.4K]
\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~{{ 4}} &,&{{ -2}}~) 
%  (c,d)
&&(~{{ 5}} &,&{{ 0}}~)
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{5-(-2)}{0-4}\implies \cfrac{5+2}{0-4}\implies -\cfrac{7}{4}

\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-2)=-\cfrac{7}{4}(x-4)
\\\\\\
y+2=-\cfrac{7}{4}(x-4)\implies y+2=-\cfrac{7}{4}x+7\implies y=-\cfrac{7}{4}x+9

The following table shows the salary of 7 people in an office last year.
kotegsom [21]

Answer:

a.  £24,714.29

b. £16,833.33

Step-by-step explanation:

The calculation of mean income is given below:-

Mean income = Total addition of salaries ÷ Number of workers

= £9,500 + £25,000 + £13,250 + £72,000 + £12,750 + £29,500 + £11,000

= £173,000 ÷ 7

= £24,714.29

Now,

the Mean income excluding Deva's salary:

= Formula of Mean income

= Total addition of salaries excluding Deva salary ÷ Number of workers

= (£9,500 + £25,000 + £13,250 + £12,750 + £29,500 + £11,000) ÷ 6

= £101,000 ÷ 6

= £16,833.33

I need answers for Question 1 and 2
Xelga [282]

Answer:  The answer to your first question would be A. 1.  This is simply because anything raised to the power of 0 is 1 no matter what.  The answer to your second question would be B. 1, for the same reason as above, anything to the power of 0 is 1.  Hope this helped and make sure to remember that rule, it is important and easy to remember!
