Answer:

72°

Step-by-step explanation:

Para el pentagono ABCDE,

m<C = (n - 2)(180)/n = (3)(180)/5 = 108

m<D = m<C = 108

Para el quadrilatero BCDE,

m<CBE + m<C + m<D + m<DEB = (n - 2)180 = 2(180) = 360

m<C = m<D = 108

m<CBE = m<DEB = x

m<CBE + m<C + m<D + m<DEB = 360

x + 108 + 108 + x = 360

2x + 216 = 360

x + 108 = 180

x = 72

The graph shows a function.<br> Find the value of b and d.

True [87]

Answer:

<em>The required values are b=-6 and d=4</em>

Step-by-step explanation:

The graph corresponds to the function

$r(x) =x^2+bx^2+8x+d$

We are required to find the values of b and d.

They can be found by using two points that are clearly visible on the graph. For example, the points (0,4) and (2,0) belong to the function. Substituting their values in the function:

$4 =0^2+b*0^2+8*0+d$

Simplifying:

4 = d

d = 4

Now use the point (2,0):

$0 =2^2+b*2^2+8*2+d$

Since d=4, and calculating

$0 =4+4b+16+4$

Simplifying:

$4b = -24$

Dividing by 4:

$b = -24/4 = -6$

$b = -6$

The required values are b=-6 and d=4

frutty [35]

Answer:

It travels 1/5 mile in one second

Step-by-step explanation:

1/10 * 2 = 2/10 = 1/5

Since the bolt of lightning travels 1/10 mile in half a second, then to find how much it travels in one a second you simply multiply 1/10 by 2, which equals 2/10, which can be simplified to 1/5.
