Answer:
The vertex will be found at (-5, -28)
Step-by-step explanation:
Vertex form uses the following formula:
y = a(x-h)^2 + k
Identify the values of h and k in your function:
(x+5)^2 - 28
h = -5, k = -28
The vertex is found with the following point:
(h,k)
Vertex: (-5, -28)
The vertex will be found at (-5, -28)
Answer:
see below
Step-by-step explanation:
9(7 + 2x)
The two factors are 9 and 7+2x
9 has one term and 7 +2x has two terms
The coefficient of the variable term is 2. x is the variable
We need to test the hypotheses:
The confidence interval for proportion is
.
Here
The z value to be used is 1.96.
The 95% CI is
.
Since 0.5 lies in the interval (0.488,0.543), we cannot reject the null hypothesis with 95% confidence.
The answer is: " 2x¹⁶ y " .

Given: "2xy (x⁵)³ " ; Simplify .
_____________________________________
Note: (x ⁵) ³ = x⁽ ⁵ * ³ ⁾ = x ⁽¹⁵⁾ ;
______________________________________
Rewrite:
2xy (x⁵)³ = 2xy x⁽¹⁵⁾ ;
Rewrite:
2 * x * x⁽¹⁵⁾ * y ;
Note: "x * x⁽¹⁵⁾ = x¹ * x¹⁵ = x⁽¹ ⁺ ¹⁵⁾ = x¹⁶ ;
Rewrite: " 2x¹⁶ y " .
