What is the vertex of y=-3x^2+6x+15? Help is much appreciated.

DENIUS [597]

Answer:

Step-by-step explanation:

Rewrite the equation in vertex form by completing the square for -3x^2 + 6x + 15. This = -3(x - 1)^2 + 18.

Set y equal to the new right side.

y = -3(x - 1)

Use the vertex form, y = a(x - h)^2 + k, to determine the values of a, h, and k.

a = -3

h = 1

k = 18

Vertex = (h, k) / (1, 18)

Previous balance:

+ $481,47→ 11/30
- $300,00 → 11/02
- $68,99 → 11 / 10
- $45,00 → 11/15
- $72,75 → 11/17
----------------------------
+ $481,47 - $113,26 =
+ $368,21

new balance:

+ $481,47→ 11/30
- $300,00 → 11/02
- $ $\diagup\!\!\!\! 68,\diagup\!\!\!\!99$ → 11 / 10 for -$58,99
- $45,00 → 11/15
- $ $\diagup\!\!\!\! 72,\diagup\!\!\!\!75$ → 11/17 for $ 0
-------------------------------------------------------------------------------------
+ $481,47 - $196,01 =
+$285,46

Answer:
$\boxed{+285,46}$

Let f(x) = x^2 and g(x) = x - 5 Find (f o g)(-2)

irina1246 [14]

Answer:

$Solution,\\f(x) = x^{2}\\g(x) = x-5\\Now, \\fog(x) = f[g(x)] = f(x-5) = (x-5)^{2} \\Put~x=-2,\\fog(-2) = (-2-5)^{2} = (-7)^{2} = 49$
