Answer:

it's the first one

Step-by-step explanation:

since all of them go up to 8 on the graph it

the graph represents it going down since the first one is the only one to go down that one represents the graph precisely.

For a triangle:
$A=\frac{b \times h}{2}$
$60=\frac{12\times h}{2}$
$120=12h$
$h=\frac{120}{12}$
$h=10yrd$

Answer:

b) $f^{-1}(x) = \frac{4x+5}{3}$

Step-by-step explanation:

b) To find the inverse function, switch the $x$ and $y$ variables and solve for $y$ :

$f(x) = \frac{3x-5}{4}\\y = \frac{3x-5}{4}\\x = \frac{3y-5}{4}\\4x = 3y-5\\4x+5 = 3y\\\frac{4x+5}{3} = y\\f^{-1}(x) = \frac{4x+5}{3}$

Verify Answer:

$f(1) = \frac{3(1)-5}{4} = -0.5\\f^{-1}(-0.5) = \frac{4(-0.5)+5}{3} = 1$

Given there are 12 parts in the ratio, we would divide 48 by 12 which equals 4. So, the ratio would be 28:20.
