Answer:
Each strip is 117.6 cm
Step-by-step explanation:
I created a proportion of hearts to others. On strip A there is 1 heart to 2 others and B there is 1 heart to 3 others. I added them and got a proportion of 2 hearts to 5 others for both. With a total of 56 hearts, I set up a proportion to determine the total stickers
2/5=56/x
When I cross multiply, I get 2x=280 and x=140
so for the 56 total hearts, I have 140 others. I added those to get the total stickers and got 196. I multiplied that by 1.2cm and got 235.2 cm for both. Since both are the same size, just divide that by 2 and get 117.6 cm each.
I hope this helps you
5x^2+30x+65=0

disctirminant=b^-4ac
disctirminant=6^2-4.1.13
disctirminant=36-52
disctirminant= -16
x1= -6+square root of -16/2.1
x1= -6+4i/2=2i-3
x2= -6- square root of -16/2.1
x2= -6-4i/2= -3-2i
Answer:
- The range of the given function is [6, + ∞)
Step-by-step explanation:
It is assumed the function is:
We know the square root is non-negative, so:
- x - 8 ≥ 0 therefore the function gets values
We can show this as:
The following interval notation are as follows;
(a) Domain:(-2,∞)
(b) Range: (-4,4)
(c) Interval(s) on which f(x) is increasing: (0,4)
(d) Interval(s) on which f(x) is decreasing: (2,6)
(e) Interval(s) on which f(x) is constant:(2, ∞)
(f) Local maxima: (0,4)
(g) Local minima:( 0,-6)
<h3>What is function?</h3>
The function is a special relationship between inputs (i.e. domain) and their outputs (known as code domain) where each input has exactly one output and the output can be traced back to that input.
There are many types of functions in mathematics. Some important types are:
- Injection function or One-to-one function: If each domain has a mapping between two sets.
- Surject functions or Onto function: When more than one element is connected from domain to domain.
- Polynomial function: A function consisting of polynomials.
- Inverse Functions: A function that can invert another function.
These were some examples of functions. It should be noted that there are several other functions such as function, algebraic functions, etc.
