The given expression can be proved using the Pythagorean identity as shown below:

$L.H.S \\ \\ 
= 1+ sec^{2} *sin^{2}x \\ \\ 
=1+ \frac{1}{cos^{2}x } sin^{2}x \\ \\
=1+tan^{2}x \\ \\ 
=sec^{2}x \\ \\ 
= R.H.S 
$

Thus, the Left hand side has been proved equal to Right Hand Side.

How do i find a formula for "1+3+5+7+......+(2n-1)

nata0808 [166]

Answer:

Step-by-step explanation:

common difference d=3-1=2

first term a=1

an=a+(n-1)d

2n-1=1+(l-1)2

2n-1=1+2l-2

2n-1=2l-1

l=n

(i used l for number of terms)

number of terms=n

$S_{n}=\frac{n}{2} (first ~term+last~term)\\=\frac{n}{2} (1+2n-1)\\=n^2$

If y varies directly as the square root of x and y=12 when x = 16 , find x when y = 15

a_sh-v [17]

= 19 this is the answer I'm guessing since 16-12= 4 so 16 is 4 more than 12

Does this equation y=87.2/x represent a direct or inverse variation?

Lorico [155]

Answer:

Inverse relationship

Step-by-step explanation:

The equation we are looking at is;

y = 87.2/x

which implies xy = 87.2

If it was a direct relationship

y = constant * x

if it was inverse, it would have been

y * x = constant

since 87.2 is a constant, the question looks exactly like the second scenario.

This means that what we have is an inverse relationship
