limit as x approaches 10 of (7x^2-70x)/(x^2-100)

x \to 10 lim (\frac{7 x ^{2} - 70 x}{x ^{2} - 100})

\frac{7}{2}

Decimal Notation

3.5

Solution steps

x \to 10 lim (\frac{7 x ^{2} - 70 x}{x ^{2} - 100})

Simplify

\frac{7 x ^{2} - 70 x}{x ^{2} - 100} : \frac{7 x}{x + 10}

= x \to 10 lim (\frac{7 x}{x + 10})

Plug in the value

x = 10

= \frac{7 \cdot 10}{10 + 10}

Simplify

\frac{7 \cdot 10}{10 + 10} : \frac{7}{2}

= \frac{7}{2}

\int cos (0.5 x) d x

e^{- \frac{x}{2}}

t e^{t}

y^{^{'}} - 2 y = x^{2} e^{2 x}

\frac{d}{d x} (e^{5 x - 3})
