Area of trapezoid :

\boxed{ \frac{1}{2} \times sum \: of \: parallel \: sides \times height }

=》

\boxed  {\frac{1}{2}  \times (9 + 5) \times 7}

=》

\boxed  {\frac{1}{2}  \times 14 \times 7}

=》

\boxed{7 \times 7}

=》

\boxed{49}

\boxed {\mathfrak{area  = 49 \:in {}^{2} }}

Given the parent function of f(x) = x^(4, what change will occurr when the function is changed to f((1)/(2) x))
jarptica [38.1K]

Answer:

The graph of the function f( (1/2)x ) will expand across x-axis

Step-by-step explanation:

We have been given the function:

f(x) = x⁴

If we substitute x = (1/2)x into the given equation, we get:

f((1/2)x) = ( (1/2)x )⁴

We can simplify the equation

f((1/2)x) = = (1/2)⁴ x⁴

f((1/2)x) = = (1/16) x⁴

Graph of both of the functions is shown below. We can clearly see that that the graph of the function f((1/2)x) = = (1/16) x⁴ expands horizontally on x-axis as compared to the graph of f(x) = x⁴

Which are the roots of the equation 3m^2-5m+1=0
Svetradugi [14.3K]

Answer:

       -(-5) ± √13             5 ± √13

x = ----------------------- = ---------------

              2(3)                       6

Step-by-step explanation:

This is a quadratic equation, with coefficients 3, -5 and 1.

The discriminant, b² - 4ac, turns out to be (-5)² - 4(3)(1), or 25 - 12  =  13

Thus, the roots are:

       -(-5) ± √13             5 ± √13

x = ----------------------- = ---------------

              2(3)                       6
