A circle is drawn to represent a pizza with a 12
fredd [130]

Answer:

Step-by-step explanation:

diameter/2 = radius

12/2 = radius

radius = 6

The outer edge means you are measuring the circumference of the pizza.

Circumference = 2(pi)(radius)

Circumference = 2(pi)(6)

You are only finding 1/8 of the circumference

Therefore you are multiplying the circumference by 1/8

Length of 1 slice = (1/8)((2)(pi)(6)) = (12/8)(pi) = (3/2)(pi) = (3(pi)) / (2) or 4.71 inches

Use a double angle or half angle identity to find the exact value of each expression
inna [77]

<em>θ</em> is given to be in the fourth quadrant (270° < <em>θ</em> < 360°) for which sin(<em>θ</em>) < 0 and cos(<em>θ</em>) > 0. This means

cos²(<em>θ</em>) + sin²(<em>θ</em>) = 1   ==>   sin(<em>θ</em>) = -√[1 - cos²(<em>θ</em>)] = -3/5

Now recall the double angle identity for sine:

sin(2<em>θ</em>) = 2 sin(<em>θ</em>) cos(<em>θ</em>)

==>   sin(2<em>θ</em>) = 2 (-3/5) (4/5) = -24/25

Somebody please answer these if your good at math and find the slope please ... due inna hour..
saveliy_v [14]

Answer:

See below

Step-by-step explanation:

  • Find a point on the line where it touches a gridpoint and start from there. Slope is defined as rise/run, so from that point you either go up or down for rise, and left or right for run to find another point closest where the line touches a gridpoint.
  • A graph with a slope that looks like \ will be negative and a slope that looks like / will be positive

Find the value of y. images attached.
telo118 [61]

Answer:

<h3>The answer is option D</h3>

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of y

To find the value of y we use tan

\tan(28)  =  \frac{y}{35}  \\ y = 35 \tan(28)  \\ y = 18.6098301...

We have the final answer as

<h3>18.61</h3>

Hope this is helps you
