F(x)= 1/4x the slope goes 0.25 upwards
X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
the center square is 20 x 20 = 400
there are 4 12 x 20 areas
12*20 = 240*4 = 960
960+400 = 1360 square inches
Answer:
There will be no change. It will still be 4/5
Step-by-step explanation:
When one performs a dilation of a triangle, all sides get affected. In this case, since the dilation is by a factor of two, the sides will double their lengths.
But recall that dilations will create similar triangles, which means that their angles at the vertices remain the same.
The trig functions of angles depend only on the actual angle they are applied to, so, since the angles remain the same, the sine value will stay the same: "4/5".
The answe is simply 4/15. to find the answer put the whole number on the bottom and the other number on top and simplify as far as possible by dividing by the common number.
