Plz answer both for 10 points.!!! Thx for the help.
ratelena [41]
Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h

23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified


24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values

.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.

Let g(x) = 2x and h(x) = x^2 + 4. Find the value.(g o h) (0)a) 4b) 8c) 0d) 16
Paul [167]
\begin{gathered} \text{Given} \\ g(x)=2x \\ h(x)=x^2+4 \end{gathered}

Solve for (g o h)(x)

\begin{gathered} (g\circ f)(x)=g\big(f(x)\big) \\ (g\circ f)(x)=g(x^2+4) \\ (g\circ f)(x)=2(x^2+4) \\ (g\circ f)(x)=2x^2+8 \end{gathered}

Next substitute x = 0

\begin{gathered} (g\circ f)(x)=2x^2+8 \\ (g\circ f)(0)=2(0)^2+8 \\ (g\circ f)(0)=8 \end{gathered}\text{Therefore, }(g\circ f)(0)=8
