There is no question. But I'd gladly help if you had a question!
To find the area of this shape you must first find the area of the rectangle 8 x 13 = 104. Once you find the area of the rectangle you must then find the area of the triangle which is base x height divided by 2. So to find the base of the triangle you must add the 4s on the bottom and subtract it by 13. So 13-8=5 so the base of the triangle is 5, the height is 6 and 5x6 is 30. You then divide it by 2 so you get 15. Now you take the area of the rectangle,104 and subtract it by the area of the triangle, 15. The answer is 89. I hope this helps.
There is a 25% chance that they will have no injured players for one of their matches.
In total, there were 16 matches if you add them all up. In 4 of the matches, there were no injured players.
4 / 16 x 100 = 25%
First of all
x^2 +10x - 18
use
x = (-b plus or minus (<span>√<span></span></span>(b^2-4ac)))/2a
you will get
(x+5−(<span>√<span><span><span>43)</span></span><span></span></span></span>)(x+5+(<span>√<span><span><span>43</span></span><span>))</span></span></span>
K(x) = (1/4)^x
(1,4) when x = 1, k(1) = (1/4)^1 = 1/4....FALSE
(3, 1/64) when x = 3, k(3) = (1/4)^3 = 1/64....TRUE
(-1,4) when x = -1, k(-1) = (1/4)^-1 = 4....TRUE
(0, 1/4) when x = 0, k(0) = (1/4)^0 = 1....FALSE
answer
(3, 1/64)
(-1,4)
