Answer:

Step-by-step explanation:

I suppose the expression is this a^2+9a+8.

We can factor out this expression ( Remember, find two numbers that the sum is 9 and the product is 8. The numbers are 8 and 1)

a^2+9a+8=(a+1)(a+8)

What set of reflections would carry triangle ABC onto itself?
crimeas [40]
<span>The correct answer is y-axis, x-axis, y-axis, x-axis. The y-axis is the vertical line, and the x-axis is the horizontal line. If the triangle is in the upper right quadrant, and is reflected first over the y-axis, it will be in the upper left quadrant. Then, when the triangle is reflected again over the x-axis, it will be in the lower left quadrant, diagonal to the initial triangle. When the triangle is again reflected over the y-axis, it will be in the lower right quadrant, below the initial triangle. Finally, when the triangle is reflected over the x-axis, it will be on top of the original triangle in the upper right quadrant.</span>

In the diagram, CA is tangent to circle P. The e
Alecsey [184]

Answer:

C. 15 cm

Explanation:

The radius is the same in a circle. PA and PB has same length of 8 cm.

In order to find AC, find the length of PA and PC.

Here given:

  • PA = 8 cm
  • PC = PB + BC = 8 cm + 9 cm = 17 cm

Hence solve using Pythagoras theorem:

  • a² + b² = c²
  • AC² + PA² = PC²
  • AC² + 8² = 17²
  • AC² = 289 - 64
  • AC = √225
  • AC = 15

An observer at the top of a tower of height 20m sees a man due East of him at an angle of depression of 27°. He sees another man
kotegsom [21]

Answer:

  • 52.35 m

Step-by-step explanation:

<em>Refer to picture.</em>

Let the distance to men are x and y and the distance between them is d.

The angle of depreciation is 27° and 30°, hence top angle of the triangle is 63° or 60°.

<u>Find the distance from the tower to men:</u>

  • x = 20 tan 63° = 39.25 m
  • y = 20 tan 60° = 34.64 m

<u>The distance between men is:</u>

  • d = \sqrt{x^2+y^2} =\sqrt{39.25^2+34.64^2} = 52.35m

<em>Note, all numbers are rounded</em>
