Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 3, - 6), thus
y = a(x + 3)² - 6
To find a substitute (0, 0) into the equation
0 = 9a - 6 ⇒ a = 
= 
y = (x + 3)² - 6 ← in vertex form
Expand (x + 3)² and distribute by
y = (x² + 6x + 9) - 6
= x² + 4x + 6 - 6
= x² + 4x ← in standard form
Answer:
D
Step-by-step explanation:
4.2 precent of 5000 is 210. You multiply that by the year (4) because he paid 4.2 of 5000 anually. If you multiply that the answer should be 840.
3.9 precent of 5000 is 195. If you multiply that again by 6 (the year) because he paid 3.9 of 5000 anually. If you multiply that your answer should be 1170.
Now after all that subtract. 1170-840= 330

(2,7)
Answer:
Yes
Step-by-step explanation:
Pythagorean's Theorum is that a^2 + b^2 = c^2
a and b are the sides of the triangle and c is the hypotenuse. 33x33+56x56=4225 sqrt4225 is 65. Everything checks out.
