Answer: 43.4
Step-by-step explanation: if it was dilated by a bigger number than 1 then it’s goin to have a bigger area and in this case it was dilated by
4 2/3 so you multiply the area by 4 2/3 to round your answer to the nearest tenth and u get 43.4
Answer:
27.44
Step-by-step explanation:
area of the half sircle = 12.56
area of the rectangle = 40
area of the shaded protion = 40 -12.56
=27.44 square yards
You should go by 0.001
so you can graph 0.001, 0.002, 0.003, and so on
For f composite g, plug g into f
f(g)=6x^2+3
-3. -3
-3=6x^2
—. ——
6. 6
-3/6=x^2
square root of -3/6=x
then plug that number into
g composite f
f(f)=6(square root of /3/6)
Always try putting x=1 and x=-1 to see if we can find a zero.
If x=1 we get 5+8+1-2 which is not zero.
If we change the signs of the odd powers of x we get -5+8-1-2 which is zero so x=-1 is a zero and x+1 must therefore be a factor. Now we can use synthetic division to find the quadratic:
-1 | 5 8 1 -2
5 -5 -3 2
————
5 3 -2 | 0 = 5x²+3x-2 = (5x-2)(x+1).
Therefore the real zeroes are -1, 2/5, since -1 is a duplicate zero (because the cubic factorises into (5x-2)(x+1)²).
