Given that f(x) = 2x 1 and g(x) = −5x 2, solve for f(g(x)) when x = 3.

1 answer:

4 0

F(x) = 2x + 1 and g(x) = -5x + 2
f(g(x)) = 2(-5x + 2) + 1 = -10x + 4 + 1 = -10x + 5
f(g(3)) = -10(3) + 5 = -30 + 5 = -25

In rhombus ABCD, the diagonals AC and BDintersect at E. If AE=5 and BE=12, what is thelength of AB?

hram777 [196]

Diagonals that bisect each other are perpendicular and form a right angle.

AEB is a right triangle.

We can apply the Pythagorean theorem:

c^2 = a^2+b^2

Where c is the hypotenuse (longest side) and a and b the other 2 legs.

Replacing:

AB^2 = AE^2+BE^2

AB^2 = 5^2+12^2

AB^2 = 25+144

AB^2 = 169

AB=√169 = 13

Lenght of AB= 13

Choose the simplified form of the fifth term of 6C4(2x)2(-y2)4.

Katarina [22]

You didn't give us the choices. It doesn't matter. I think you're trying to write

$\displaystyle {6 \choose 4} (2x)^2 (-y^2)^4$

$= \dfrac{6!}{4! 2!} ( 4x^2 y^8)$

$= \dfrac{6(5)}{2} ( 4x^2 y^8)$

$=60x^2 y^8$

Answer: 60 x² y⁸
