Prove that : sinA/1+cosA + 1+cosA/sinA=2cosecA​
tekilochka [14]

Step-by-step explanation:

\frac{sinA}{1+cosA} +\frac{1+cos}{sinA} =2cosec\\\\\\\frac{sin^{2}A+(1+cos)^{2}  }{sinA(1+cosA)} \\\\

\frac{sin^{2}A+1+cos^{2}+2cos}{sinA(1+cosA)} \\\\ and we have sin^{2}+cos^{2} =1

so \frac{1+1+2cosA  }{sinA(1+cosA)} \\\\

\frac{2+2cosA  }{sinA(1+cosA)} \\\\

\frac{2(1+cosA)}{sinA(1+cosA)} \\\\

\frac{2}{sinA} we have \frac{1}{sin}=cosec\\

A rectangle has an area of 524.4m2. One of the sides is 6.9m in length. Work out the perimeter of the rectangle. PLEASE ANSWER!!
malfutka [58]

Answer:

<h2>165.8 m</h2>

Solution,

Area of rectangle= 524.4 m^2

Length(L)= 6.9 m

Breadth(B)=?

Now,

area = length  \times breadth \\ or \: 524.4 = 6.9 \times b \\ or \: 524.4 = 6.9b \\ or \: b =  \frac{524.4}{6.9}  \\ b = 76 \: m

Again,

Perimeter of rectangle:

2(l + b) \\  = 2(6.9 + 76) \\  = 2 \times 82.9 \\  = 165.8 \: m

Hope this helps...

Good luck on your assignment.....

The graph of f (in blue) is translated a whole number of units horizontally and vertically to obtain the graph of h(in red).
saveliy_v [14]

Answer:

h(x)=\sqrt{x-2}+4

Step-by-step explanation:

Initially the graph f (x) is shifted horizontally to the right.

When the graph shifts to right the function then becomes

f(x)→f(x-b)

Where b is the units by which it is shifted towards right .

So, in the figure we can see that it is shifted 2 units to the right .

So, f(x)→f(x-2)

Since f(x) is \sqrt{x}

So, f(x-2) =  \sqrt{x-2}

Now the new obtained graph is again shifted vertically upward

When the graphs shifts upward f(x) →f(x)+b

where b is the units by which it is shifted upward

So, our obtained f(x-2)  when shifted upward by 4 units so using the above given transformation of upward shift i.e. f(x) →f(x)+b

So,   Our new graph h(x) = f(x-2)+4

⇒  h(x)=\sqrt{x-2}+4
