Answer:
Step-by-step explanation:
Use Pythagorean theorem,
base²+altitude² = hypotenuse²
x² + 14² = 40²
x² + 196 = 1600
x² = 1600 - 196
x² = 1404
x = √1404
x = 37.47 ft
The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7
Answer:-74
Step-by-step explanation: When you are in the megatives, less is more! So -74 is actually greater then -75
Answer:
Slope = 4
Step-by-step explanation:
Use any two pairs from the table of values, say (0, 3) and (2, 11).
Slope = ∆y/∆x
Slope =
Slope =
Slope = 4
