3.7

4.10

Step-by-step explanation:

1. 6÷x +9

6÷3=2

2+9=11

2. 8x-3+y

8×2 -3+1

=16-3+1

= 16-2=14

3. 2xy

=2×5×-3

=10-3 =7

4. 2x^2-y

=2×3^2-8

=2×9-8

=18-8

=10

the radius of a circle is 10 centimeters. what is the area of a sector bounded by a 90° arc? give the exact answer in simplest f
Alex787 [66]
I hope this isn't too late! You can find the answer to this by first finding the area of the circle, A=πr². So since the radius is 10, we input that into the equation to get π100. Now, there is 360° in a circle and a sector of 90° is 1/4 of it. So to answer the question all you have to do is find 1/4 of the area of the circle. 

The answer is π25.

To solve the other questions on your assignment just think about how much the sector is of the full 360° of the circle, for example 180° is 1/2 of the circle or 270° is 3/4 of the circle, and multiply the fraction by the area of the circle.

Hope this helped, good luck! :)

Al trazar en el plano cartesiano el angulo a cuyo lado terminal es el punto de ( 3,4). Los valores de las funciones del coseno y
Igoryamba

Answer:

cos(\alpha)=\frac{3}{5}=0.6

cosec(\alpha)=\frac{5}{4}=1.25

Step-by-step explanation:

El cos(α) se define como el cociente entre el cateto adyacente y la hipotenusa.

El valor del cateto adyacente en nuestgro caso es CA = 3.

La hipotenusa se calcual de la siguiente manera:

h=\sqrt{3^2+4^2}=5

Por lo tanto, el cos(α) sera:

cos(\alpha)=\frac{3}{5}=0.6

El cosec(α)=h/CO.

El cateto opuesto CO = 4 y la hipotenusa h = 5

Por lo tanto, el cosec(α) sera:

cosec(\alpha)=\frac{5}{4}=1.25

Espero te haya sido de ayuda!
