Answer:

60°

Step-by-step explanation:

40+80 = 120

180 - 120 = 60°

Answer:

60°

Step-by-step explanation:

The sum of all three triangle angles add up to 180°. To solve for the last angle, add the sides you know together and subtract the sum from 180. This will leave you with the third angle's measurement,

40 + 80 = 120

180 - 120 = 60

What is the inverse of f(x)=(x-5)^2 for x greater or equal to 5 where function g is the inverse of function f

koban [17]

Answer:

$y=\sqrt{x}+5$

Step-by-step explanation:

The inverse of a function, is the function or rule formed by reflecting the line over y=x. This means essentially that all (x,y) values from the original function switch to (y,x).

(x,y)--->(y,x) in the new function.

If the function has points (-3,4) and (5,-2) then the inverse has points (4,-3) and (-2, 5).

We can find the equation of the inverse by switching x and y in the equation and solving for y.

This means that $y=(x-5)^2$ becomes $x=(y-5)^2$ . We now solve for y through inverse operations.

$x=(y-5)^2$

$x=(y-5)^2\\\sqrt{x} =\sqrt{(y-5)^2} \\\sqrt{x} =y-5\\\sqrt{x} +5=y$

Last week, Makayla took 8 express bus rides, which cost her $34. Which equation models the cost in dollars, c, per express bus r

arsen [322]

Based on the cost of the bus rides in total and the number of buses taken, the relevant equation would be c = 34/b.

Makayla took 8 express bus rides and this cost her $34 in total. The cost of each bus ride is therefore:

= Total cost of rides / Number of rides taken

With the cost per ride being c and the bus ride being b, the equation would be:

c = 34/b

In conclusion, to find the cost of each bus ride, use the equation c = 34/b.
