Answer:
h(x) = -16 xx + 64 x + 8 , in Standard Form
Vertex at (2, 72) maximum height at 72 feet
Step-by-step explanation:
We have: h(x) = −16(x − 2)2 + 72
this function is in Vertex form.
the Standard form is when we expand out the expression.
h(x) = -16 *( x*x - 4x + 4) + 72
h(x) = -16 xx + 64 x - 64 + 72
h(x) = -16 xx + 64 x + 8
Vertex at (2, 72) maximum height at 72 feet
2√20 and 4*5^1/2. Explanation Below:
---
When we simplify 2√20, we get 4√5, and 5^1/2 is √5. Therefore, 4*5^1/2 is 4√5.

Answer:
$64,269.65
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 6.25% into a decimal:
6.25% -> -> 0.0625
Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:
The value of Sara's investment after 30 years will be $64,269.65
Answer:
x = -1/4, y = 5/4.
Step-by-step explanation:
Because of the absolute value equation y = |x - 1| the value of y must be positive.
Solving x - 1 = 3x + 2 :
2x = -3
x = -3/2 and y = -5/2 so x= -3/2 is not a solution.
x - 1 xcan also be negative so we have the equation
- (x - 1) = 3x + 2
1 - x = 3x + 2
-1 = 4x
x = -1/4
y = 1 - - 1/4 = 5/4.
