Area of a triangle= 1/2 (b)(h).
Area= 1/2 (11)(7)
Area= 77/2
Area= 38.5
Answer:
the root of -1 is -1
Step-by-step explanation:
When multiplied by itself, the root is typically a specified number of times gives a specified number or quantity. So -1 × -1 = -1
So there you go
There is a 1/3 chance that a red marble would be chosen.
To find out you put add up the marbles, so they will make 12 marbles.
Since there are 4 red you put 4/12.
4/12 simplified is 1/3.
So the chance of a red marble being picked is 1/3.
The function notation f(x)=2x-4 means replace the x on the right-hand side with the value in parentheses on the left.
For example, f(y)=2y-4; f(4)=2(4)-4=4; f(1)=2(1)-4=-2 and so on.
The same principle applies to g(x), for example
g(2)=4(2^2)-3=13,
g(x+1)=4(x+1)^2-3=4(x^2+2x+1)-3=4x^2+8x+4-3=4x^2+8x+1
and so on.
(g of f)(x) is another way to write g(f(x)), therefore
g(f(x))
=g(2x-4) [because f(x)=2x-4
=4(2x-4)^2-3
=4(4x^2-16x+16)-3
=16x^2-64x+64-3
=16x^2-64x+61
3p^4(4p^4 + 7p^3 + 4p + 1)
