Answer:
28 minutes
Step-by-step explanation:
we know that
1) A factory manufactures a metal piece in 32 minutes
2) New technology allowed the factory to cut that time by 8%
Remember that
In this part 32 minutes represent the 100%
To find out how long it take to manufacture the piece, multiply 32 minutes by the factor 0.92
3) Then another improvement cut the time by 5%
Remember that
In this part 29.44 minutes represent the 100%
To find out how long it take to manufacture the piece now, multiply 29.44 minutes by the factor 0.95
<span>1. </span><span>Give the word phrase of 12x
=> 12 is an integer
=> x in a variable or also called as unknown number
=> 12 = twelve
There the word phrase of this given number is
=> twelve times the number or twelve times x
In giving the word phrase of a certain
equation, simply give the word statement of each digits, variable and
operations involve
Another example:
=> 5x + 1 – 2
=> five times the number added with one subtracted with two.</span>
The function is in vertex form of a quadratic function.
Vertex form is f(x)=a(x-h)^2+k
The vertex is (h, k)
In this case, our vertex is (2, 2). The a value is positive which means that the graph points up. Since the graph points up, the vertex is the minimum, the lowest point of the graph. The range refers to y-values, so the range of the function is y/y>2. It can also be written as 2≤y<span>≤positive infinity.</span>
