1/6, because since there are six sides, and you need one of them to land, it is a 1/6 probability.

What is the measure of AC?<br> Enter your answer in the box.<br> (4x - 5.5)<br> (5x+25)

Gnoma [55]

Answer:

The measure of arc AC is 85°

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

so

m∠ABC=(1/2)[arc AC]

substitute

(4x-5.5)°=(1/2)[5x+25]°

(8x-11)°=(5x+25)°

8x-5x=25+11

3x=36

x=12°

Find the measure of arc AC

arc AC=(5x+25)°

arc AC=5(12)+25=85°

If a polyhedron has 5 faces and 7 vertices, then it must have how many edges? Please show step-by-step work

Juli2301 [7.4K]

Answer:

10 edges

Step-by-step explanation:

we know that

The Euler's formula state that: In a polyhedron, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

$V - E + F = 2$

in this problem we have

$V=7\\E=?\\F=5$

substitute the given values

$7 - E + 5 = 2$

solve for E

Combine like terms in the left side

$12 - E = 2$

subtract 12 both sides

$- E = -10$

Multiply by -1 both sides

$E =10$

What is the equation in vertex form of a

gulaghasi [49]

Answer:

B.

Step-by-step explanation:

Vertex with (2,4) means that the equation will have:

y=a(x-2)^2 + 4

Open downwards means that the a will be negative:

so: y = -a (x-2)^2 + 4

Stretched by a factor of 3 means that the a=3

So if we combine all of these, we will get the equation:

y = -3 (x-2)^2 + 4
