What is the vertex of the quadratic equation y = - 1/3 (x + 2)^2 +5

Wewaii [24]

Answer:

<h2>(-2, 5)</h2>

Step-by-step explanation:

$\text{The vertex form of a quadratic equation:}\\\\y=a(x-h)^2+k\\\\(h,\ k)-vertex\\---------------\\\text{We have:}\\\\y=-\dfrac{1}{3}(x+2)^2+5=-\dfrac{1}{3}(x-(-2))^2+5\Rightarrow h=-2\ \text{and}\ k=5\\\\\text{therefore the vertex is:}\ (-2,\ 5)$

Solve for x to the nearest degree.

Archy [21]

Answer:

71

Step-by-step explanation:

The square represents 90 degrees.

A triangle’s three angles ALWAYS adds up 180.

To find the missing angle:

180 - 90 = 90

90 - 19 = 71.

Therefore, the answer is 71

The new triangle is gonna be bigger. But how big? Let’s look at A.
A= 2,8

Look at A’, it’s 6,24. See a pattern??
Multiply 2,8 by 3. It’s triple the amount, therefore the scale factor is 3.

To double check, multiply by 3 to B and C and see what you get.
