Bonjour!

For A, the two angles are congruent by the Corresponding Angles are Congruent Theorem/Postulate.

For B, the two angles are congruent by the Vertical Angels are Congruent Theorem/Postulate.

As for C, the two angles are congruent by the Same Side Exterior Theorem/Postulate.(Though I am uncertain if that is the correct name for this one)

Hope that helps :)

At the beginning of the fall, the water level of a lake is 12

spayn [35]

x = normal water level

x - 12 - 13 = x - 25

so it is 25 feet below the normal water level

The data above can be modeled by the function f(x) = 0.0425x^2 + 0.07381x - 0.49107 . Using this equation, predict the skid dist

nataly862011 [7]

Answer:

f(50) = 109.44943 feet

Step-by-step explanation:

Modeling

The model of a situation where the skid distance f is measured against the car speed x can be expressed as:

$f(x) = 0.0425x^2 + 0.07381x - 0.49107$

Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:

$f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107$

$f(50) = 106.25 + 3.6905 - 0.49107$

f(50) = 109.44943 feet
