If g (x)= x^2-5, where does the graph g (x) cross the x-axis?

1 answer:

3 0

The graph crosses the x axis where g(x) = 0 , so:-

x^2 - 5 = 0
x^2 = 5
x = sqrt5 or -sqrt5

so grapg corosses the x axis at (-sqrt5,0) and (sqrt5, 0)

A baker has 10 cups of sugar to make cookies. Each batch calls for 1 1/3 cups of sugar.

disa [49]

$\bf \textit{he can make }10\div 1\frac{1}{3}\qquad or\qquad \cfrac{10}{1\frac{1}{3}}
\\\\\\
1\frac{1}{3}\implies \cfrac{1\cdot 3+1}{3}\implies \cfrac{4}{3}\\\\
-----------------------------\\\\
\cfrac{\frac{a}{b}}{\frac{c}{{{ d}}}}\implies \cfrac{a}{b}\cdot \cfrac{{{ d}}}{c}\qquad thus\\\\
-----------------------------\\\\$

$\bf \cfrac{10}{\frac{4}{3}}\implies \cfrac{\frac{10}{1}}{\frac{4}{3}}\implies \cfrac{10}{1}\cdot \cfrac{3}{4}\implies \cfrac{30}{4}\implies \cfrac{15}{2}\implies \boxed{7\frac{1}{2}}
\\\\\\
because\implies \cfrac{7\cdot 2+1}{2}\implies \cfrac{15}{2}$
