No because the triangle’s angle is less than 90 degrees if it was a right angle triangle it would have a square marking the angle.

1 5/6 divided by 11/12

deff fn [24]

First convert the mixed number to a fraction: 1 5/6 = 11/6.
$\frac{\frac{11}{6}}{\frac{11}{12}}=\frac{11}{6}\times\frac{12}{11}=2$

If f and g are differentiable functions for all real values of x such that f(1) = 4, g(1) = 3, f '(3) = −5, f '(1) = −4, g '(1)

belka [17]

Answer:

h'(1)=0

Step-by-step explanation:

We use the definition of the derivative of a quotient:

If $h(x)=\frac{f(x)}{g(x)}$ , then:

$h'(x)=\frac{f'(x)*g(x)-f(x)*g'(x)}{(g(x))^2}$

Since in our case we want the derivative of $h(x)$ at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:

$h'(1)=\frac{f'(1)*g(1)-f(1)*g'(1)}{(g(1))^2}$

which, by replacing with the given numerical values:

$f(1) =4\\g(1)=3\\f'(1)=-4\\g'(1)=-3$

becomes:

$h'(1)=\frac{f'(1)*g(1)-f(1)*g'(1)}{(g(1))^2}=\\=\frac{-4*3-4*(-3)}{(3)^2}=\frac{-12+12}{9} =\frac{0}{9} =0$

The cost of a ticket increases by 10% to £18.15<br> Work out the original cost.

Licemer1 [7]

Answer:

£16.50

Step-by-step explanation:

$x \times (1+\frac{10}{100} )=18.15$

$x \times \frac{110}{100} =18.15$

$\frac{110}{100} x=18.15$

$1.1x=18.15$

$\frac{1.1x}{1.1}=\frac{18.15}{1.1}$

$x=16.5$
