The vertex of the graph is (2,-4). It is a minimum as it is the lowest point on the parabola facing upwards. This would be option C.
Answer:
82
Step-by-step explanation:
Let the unknown number be x
If an unknown number is added to 8, this is expressed as;
8 + x
<em>If The sum is then divided by 9 to give the answer 10, then;</em>
<em>(8+x)/9 = 10</em>
<em>Cross multiply</em>
<em>8 + x = 9 * 10</em>
<em>8 + x = 90</em>
<em>x = 90 - 8</em>
<em>x = 82</em>
Hence the unknown number is 82
Answer:
The number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.
Step-by-step explanation:
Let
x: number of days
y: amount of potatoes
We can express the amount of potatoes in each warehouse using linear equations:
Warehouse #1: 
Warehouse #2: 
We need to find the value of x when 
Substituting the expressions for y1 and y2 in
:

Applying distributive law:

Solving the equation by subtracting 108x and 180 on both sides:



Now we divide by 12 on both sides:

Therefore, the number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.
Answer:
91 feet
Step-by-step explanation:
Substitute s = 2 into 155 - 16s^2.
155 - 16 * (2)^2
155 - 16 * 4
155 - 64
91 feet.
