180:60 in its simplest from

kipiarov [429]

Answer:

3:1

You can easily figure out that 60 is a factor of 180 bc 6 is a factor of 18.

So you can simplify it to 18:6

Then divide both sides by 6 and you will get 3:1

Hope this helps ;)

Answer:

a) True

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0$

Step-by-step explanation:

Step(i):-

Given that the definite integration

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha$

we know that the trigonometric formula

sin²∝+cos²∝ = 1

cos²∝ = 1-sin²∝

step(ii):-

Now the integration

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha = \int\limits^\pi _0 {(\sqrt{cos^{2} \alpha } } \, )d\alpha$

= $\int\limits^\pi _0 {cos\alpha } \, dx$

Now, Integrating

$= ( sin\alpha )_{0} ^{\pi }$

= sin π - sin 0

= 0-0

= 0

Final answer:-

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0$

Give the zeros (if any) of the quadratic function f(x)=3(x-4)(x+11).

maxonik [38]

Set each of the binomials equal to zero and solve for x. The two values will be the zeros of the equation:
(x-4) = 0 (x+11) = 0

x-4 = 0 x + 11 = 0
x = 4 x = -11

The zeros of the equation are -11 and 4
