EXPLANATION
The given line has slope,
and
We can find the equation in the point slope form, which is given by,
We substitute the point and slope to get,
We can also simplify further to get,
We make y the subject to get,
This is called the slope intercept form.
We could also write in standard form to get
Or
Answer:
(3, 5)
Step-by-step explanation:
It would be (3, 5) because since Juans house is in the same quadrant as the school there wouldn't be any negative numbers in the coordinates. The only coordinate that doesn't have negative numbers is (3, 5). That's your answer.
The answer is D: 16,800 because you multiply the principal ($6,000), rate (7%), and time (4 years) to get the interest
Vertex is calculated by -b/2a
So we have -(-5)/2(2)=5/4
The root is determined through the quadratic formula:
x=(-b+sqrt(b^2-4ac))/2a
x=(-(-5)+sqrt(-5^2-4(2)(-604)))/2(2)
x=(5+sqrt(25-4832))/4
x=(5+sqrt(-4807))/4
So the root is some imaginary number
Hope this helped!
You know from the definitions of trig functions that
.. tan(42°) = (height of courthouse above measuring device)/(distance to courthouse)
.. (height of courthouse above measuring device) = tan(42°)*(305 ft) ≈ 274.6 ft
Since the measuring device is 5 ft high, the height of the courthouse is approximately 280 ft. (selection C)
