Answer:
Step-by-step explanation:
If a = 0, f(a) = f(0) = 0 + 0 + 7 = 7;
If a = 1, f(1) = 3(1^2) + 2(1) + 7 = 12;
and so on. Normally an 'a' value would be given as part of this problem.
Actually, the value of f(a) is given and is f(a) = 3a^2+2a+7 for input value a.

28.6% of city employees ride the bus to work. Last year, 29.7% of city employees rode the bus to work. What is the relative change from last year to this year?
(Express your answer rounded correctly to the nearest tenth of a percent!)
A percentage is a way to describe a part of a whole. The relative change from last year to this year is 3.7%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
28.6% of city employees ride the bus to work, therefore, the final value is 28.6. While Last year, 29.7% of city employees rode the bus to work, therefore, the initial value is 29.7.
Since relative change means change with respect to some value. Thus, the relative value with respect to last year is,
Relative value = (29.7-28.6)/29.7 = 0.037 = 3.7%
Hence, the relative change from last year to this year is 3.7%.

a. The Gap purchased inventories totaling $10,392 million for the fiscal year ended February 2, 2019. Use the financial statement effects template to record cost of goods sold for The Gap's fiscal year ended February 2, 2019. (Assume accounts payable is used only for recording purchases of inventories and all inventories are purchased on credit.)
b. What amount did the company pay to suppliers during the year? Record this with the financial statement effects template.
I'm not sure how to show these amounts on the financial statement effects template.
The cost of goods sold is $10,258 million and the Cash paid to supplier is $10,447 million.
Cost of goods solda. Cost of goods sold
Cost of Goods Sold=Beginning Inventories + Purchases – Ending Inventories
Cost of goods sold = $1,997 + $10,392 - $2,131
Cost of goods sold = $10,258
b. Cash paid to supplier
Cash paid=2015 Beginning balance + Purchases - 2015 Ending balance
Cash paid = $1,181 + $10,392 - $1,126
Cash paid = $10,447
Therefore the cost of goods sold is $10,258 million and the Cash paid to supplier is $10,447 million.

the length of a rectangle is 5 cm less than 3 times its width. The perimeter is 62 cm.
What is the length?
Answer:
length=22 [cm].
Step-by-step explanation:
1) if the length is 'l' and the width is 'w', then it is possible
2) to write the given perimeter: 62=2(l+w), - this is the 1st equation of system;
3) to write the condition 'the length of a rectangle is 5 cm less than 3 times its width' as 3w-5=l, - this is the 2d equation of the system.
4) using two equations above it is possible to make up the next system:
[tex]\left \{ {{2(w+l)=62} \atop {3w-5=l}} \right. \ = > \ \left \{ {{w+l=31} \atop {3w-l=5}} \right. \ = > \ \left \{ {{l=22} \atop {w=9}} \right.[/tex]
5) finally, the length=22 [cm].

Answer:
Two functions which satisfies the H(x) are f(x) = 2x - 4, (x) = x⁵ and
f(x) = 2x, g(x) = x⁵ - 2
Step-by-step explanation:
The given question is based on the decomposition of a given function into two functions
Decomposition of a function :- functional decomposition is the process of resolving a functional relationship into its constituent parts in such a way that the original function can be reconstructed from those parts by function composition
so the function given in the question is H(x) = 2x⁵ - 4
now by using the concept of decomposition of a function we can find two functions f and g
therefore,
f(x) = 2x - 4
and g(x) = x⁵
similarly we can find another pair which satisfies the function H(x)
f(x) = 2x
and g(x) = x⁵ - 2

Part 1: Finding [tex](g\circ h)(x)[/tex]
Note that [tex](g\circ h)(x)=g(h(x))[/tex]
In this case, it is [tex]g(\sqrt{x+4})=(\sqrt{x+4})^{2}-3=x+4-3=\boxed{x+1}[/tex]
Part 2: Domain
For the domain, we need to make sure the radicand of h(x) is greater than or equal to 0, so we get [tex]x+4 \geq 0 \longrightarrow \boxed{x \geq -4}[/tex]
The composition (g ο h) = x+ 1 and the domain of the composition (g ο h) is = (-∞ , ∞).
The composition (g ο h) means that the function g(x) composes of h(x) that is g(h(x)). So we have to put the the values of h(x) in the function g(x).
Now here it is given that
g(x) = [tex]x^{2} -3[/tex] and h(x) = [tex]\sqrt[2]{x + 4}[/tex]
so to get (g ο h) we have to replace the x with the value of h(x)
That gives :
g(h(x)) = [tex]\sqrt[2]{x+4} ^{2} - 3[/tex]
g(h(x)) = x + 4 - 3 = x +1
So the composition (g ο h) = x+ 1
The domain of the function is the values of x for which the function is defined.
so the domain of the composition (g ο h) is :
g(h(x)) = x+ 1
This function is undefined for no value of x .
So its domain is (-∞ , ∞).
