NEED HELP ASAP, 40 POINTS THANKS
Gwar [14]

Answer:

If KE = OS then we can deduce that the trapezoid is constructed of 3 equilateral triangles and thus we can easily work out the angles.

OSK = 60

SKE = 120

KEP = 120

EPO  = 60

We can also easily work out the perimeter since we can deduce that PE = SK = KE and thus the perimeter is 5 * 8 = 40

Determine the maximum number of zeros. Then, determine the x-intercepts of the function. x^3-3x^2-22x+24
JulijaS [17]

Answer:

Three zeros x=-4,\ x=1,\ x=6

x-intercepts: (-4,0), (1,0), (6,0)

Step-by-step explanation:

Plot the graph of the function y=x^3-3x^2-22x+24 on the coordinate plane. This graph intersects the x-axis at three different points (see attached diagram):

  • (-4,0);
  • (1,0);
  • (6,0).

This means x=-4,\ x=1,\ x=6 are zeros of the function y=x^3-3x^2-22x+24

Cos60° = 0.5

Any angle less than 90° is an acute angle.

Therefore, 60° is the acute angle.

Convert 18% to a fraction in lowest term
Lemur [1.5K]

Answer:

\frac{9}{50}

Step-by-step explanation:

This is the answer because:

1) 185 equals to \frac{18}{100} because 18% is equal to 0.18 which is \frac{18}{100}

2) \frac{18}{100}  to it's lowest terms is \frac{9}{50}

3) It's lowest terms is  \frac{9}{50} because 18/2 is 9 and 100/2 is 50

4)  \frac{9}{50} can't be simplified any further because 9 and 50 don't have any common factors

Hope this helps! :D
