Answer:

72°

Step-by-step explanation:

There are 5 blades, equally spaced.  So the angle between adjacent blades is 360° / 5 = 72°.  So you can rotate the fan 72° and the blades will align again.

This is the graph of f(x). What is the value of f(3)?
Paul [167]

Answer:

The value of f(3) is 8 ⇒ D

Step-by-step explanation:

  • In the function f(x) = y, y is the corresponding value of x
  • Ex: If f(a) = b, then the value of y = b at x = a

Let us solve the question

∵ The given figure represents the function f(x)

→ That means every point on the graph represents f(x) = y

∴ f(x) = y

∵ We need to find f(3)

→ That means we need the value of y at x = 3

∴ x = 3

Look at the graph and find the y-coordinate of the point that lies on the curve and has x-coordinate = 3

→ Each small square on the x-axis represents 1 unit, and on the y-axis

   represents 2 units

∵ There is a point on the graph that has x-coordinate = 3

∵ The y-coordinate of this point is 8

∴ The point (3, 8) lies on the graph of f(x)

∴ x = 3 and y = 8

∴ f(3) = 8

∴ The value of f(3) is 8

Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .
Allisa [31]

Answer:

We divided the figure into 1 triangle and 2 rectangles.

Adding up the area of them, we get the total area:

A = 14 x (10 + 8 + 12 - 16)/2 + 8 x 5 + 6 x (12 + 8)

   = 258 (yd2)

Hope this helps!

Papi sold candles at the fair. She sold $169.74 on Friday, $235.95 on Saturday and $219.21 on Sunday. What were her average sale
Galina-37 [17]
To find the average you would add the three numbers together 169.74+235.95+219.21
to get a total of $624.90 divide that number by 3 to get the average which is $208.30 as the average sale per day
