Given:
edge 1 = 3x - 4
edge 2 = x² - 1
edge 3 = 2x² - 15

perimeter if x = 4

edge 1 = 3(4) - 4 = 12 - 4 = 8
edge 2 = 4² - 1 = 16 - 1 = 15
edge 3 = 2(4²) - 15 = 2(16) - 15 = 32 - 15 = 17

Perimeter = 8 + 15 + 17 = 40 feet.

I don't understand this question, picture attached.
mina [271]

We can find this using the formula for arc length (where r is the radius of the circle and \theta is the central angle in radians):

\textrm{Arc Length} = r\theta


In our problem, we are given 12 = 8\theta. This means that:

\theta = \dfrac{12}{8} = \boxed{\frac{3}{2}}


The measure of the angle is 1.5.

I need help on my math
shtirl [24]

Answer:

y = -5/4x - 4

Step-by-step explanation:

The equation they give you is in slope intercept form.  y=mx+b.  The m is the slope (-5/4).  Since they want a parallel line you keep the same slope for point slope form.  Point slope formula is y-y1=m(x-x1). the y1 and x1 are where you plug in the coordinates they give you.

y - 1 = -5/4x (x + 4)

y - 1 = -5/4x - 5

y = -5/4x - 4

. If Henry plays both games conservatively (CC), find the probability that Henry will earn
larisa86 [58]

Answer:

a)  2/2 + 2/2 = 2

b)  2/2 + 1/2  = 3/2

c)  2/2 + 0/2  = 1

d)  0/2 + 0/2 = 0

Step-by-step explanation:

a) 2 points :  2/2 + 2/2 = 2    

            if henry wins both games than we get  probability =2

b) 1  1/2 or 3/2 :  2/2 + 1/2 = 3/2

             if henry wins one game and tie another game  we get probability =3/2

c) 1 point:  2/2 + 0/2 = 1

              if henry wins one game and loose second game, we get                                                       probability 1

d) 0 points: 0/2 + 0/2 = 0

                 if henry loose both games we get probability 0
