express y= x² + 2x + 3 in the form of y= (x-h)² + k
Given:
The equation is
[tex]y=x^2+2x+3[/tex]
To find:
The vertex form of the given equation, i.e., [tex]y=x^2+2x+3[/tex].
Solution:
We have,
[tex]y=x^2+2x+3[/tex]
It can be written as
[tex]y=(x^2+2x)+3[/tex]
Add and subtract square of half of coefficient of x, i.e., [tex]\left(\dfrac{2}{2}\right)^2=1[/tex].
[tex]y=(x^2+2x+1)-1+3[/tex]
[tex]y=(x^2+2(x)(1)+1^2)+2[/tex]
[tex]y=(x+1)^2+2[/tex] [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]
Therefore, the required form of given function is [tex]y=(x+1)^2+2[/tex].

The width of a box in the shape of a rectangular prism is 4 inches more than the height h . The length is the difference of 9 inches and the height. A. Write a polynomial that represents the volume of the box in terms of its height (in inches). B. The volume of the box is 180 cubic inches.
Answer:
[tex](a)[/tex] [tex]V = -H^3+ 5H^2 + 36H[/tex]
[tex](b)[/tex] [tex]Length = 5in; Width = 9in; Height = 5in[/tex] or [tex]Length = 3in; Width = 10in; Height = 6in[/tex]
Step-by-step explanation:
Let:
[tex]W=Width; L = Length; H = Height[/tex]
Given
[tex]W = 4 + H[/tex]
[tex]L = 9 - H[/tex]
Solving (a): The polynomial for the volume in terms of height
Volume (V) is calculated using:
[tex]V = L * W * H[/tex]
[tex]V = (9 - H) * (4 + H) * H[/tex]
Expand
[tex]V = (9 - H) * (4H + H^2)[/tex]
Open brackets
[tex]V = 36H + 9H^2 - 4H^2 - H^3[/tex]
[tex]V = 36H + 5H^2 - H^3[/tex]
Rewrite as:
[tex]V = -H^3+ 5H^2 + 36H[/tex]
Solving (b): The dimensions when Volume = 180
Substitute 180 for V in: [tex]V = -H^3+ 5H^2 + 36H[/tex]
[tex]180 = -H^3+ 5H^2 + 36H[/tex]
Rewrite as:
[tex]H^3 - 5H^2 - 36H + 180 = 0[/tex]
Factorize:
[tex]H^2(H - 5) - 36(H - 5) = 0[/tex]
[tex](H^2 - 36)(H - 5) = 0[/tex]
Express [tex]H^2 - 36[/tex] as difference of two squares
[tex](H - 6)(H + 6)(H - 5) =0[/tex]
This gives:
[tex]H - 6 =0==> H = 6[/tex]
[tex]H + 6 =0==> H = -6[/tex]
[tex]H - 5 =0==> H = 5[/tex]
Since the height can not be negative, then H = 5 or H = 6
Recall that:
[tex]W = 4 + H[/tex]
[tex]L = 9 - H[/tex]
When H = 5
[tex]W = 4 + 5 = 9[/tex]
[tex]L = 9 - 5 = 4[/tex]
When H = 6
[tex]W = 4 + 6 = 10[/tex]
[tex]L = 9 - 6 = 3[/tex]
Hence, the dimensions of the box are:
[tex]Length = 5in; Width = 9in; Height = 5in[/tex]
or
[tex]Length = 3in; Width = 10in; Height = 6in[/tex]
The volume of the box is given by -h³ + 5h² + 36h
Volume
Volume is the amount of space occupied by a three dimensional object. The volume (V) of a box is given by:
V = length * width * height
Let h represent the the height, hence width = h + 4, length = (9 - h)
V = h(h + 4)(9 - h) = h(5h -h² + 36) = -h³ + 5h² + 36h
For a volume of 180 in³:
180 = -h³ + 5h² + 36h
h = 5 or 6.
The volume of the box is given by -h³ + 5h² + 36h

In this figure, ST is a line.
What is the value of x?
BTW that says 2/3x
Answer:
x=108 degrees
Step-by-step explanation:
Since ST is a straight line, it measures 180 degrees. This means that x+(2/3)x=180. The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540; which is ultimately x=108.
Answer: x=108 degrees
Step-by-step explanation:
Since ST is a straight line, it measures 180 degrees.
This means that:

A square has 4 equal sides, so the piece of confetti will have 4 sides of the exact same length.
Find the length of each side by dividing the perimeter by 4
28/4
= 7
So, each side of the confetti piece is 7 mm

The volume of a cone is:

[tex]\frac{V_2}{4} = \frac 13 r^2h[/tex]
Substitute [tex]\frac{V_2}{4} = \frac 13 r^2h[/tex] in [tex]V_1 = \frac 13 \pi r^2 h[/tex]
So, we have:
[tex]V_1 = \frac{V_2}{4} * \pi[/tex]

Right triangle:
Right triangle has one of its sides as 90 degrees. The sides of a right triangle can be found using trigonometric ratios as follows;
cos 35 = adjacent / hypotenuse
where
adjacent side = 5 inches
c = hypotenuse

Answer:
using above inequality equation, we can find the total hours in which the clown can be at the party
The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Dan is planning an event for which the total cost cannot exceed $400.
And, Dan plans to spend $180 on food and to hire a clown at the rate of $35 per hour.
Now,
Let number of hours = h
So, We can formulate;
Total spend money = $180 + $35h
Hence, The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400
Thus, The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;

A family has two cars. The first car gets 25 miles per gallon and the second car gets 15 miles per gallon. In a week the two cars went 725 miles and consumed 35 gallons of gas. How much gas did each car use?
Answer:20 and 15 gallons
Step-by-step explanation:
Given
The first car gets 25 miles per gallon
The second car gets 15 miles per gallon
Two cars consumed 35 Gallons
they went for 725 miles in total
suppose the first car consumes x gallons
so, the second car consumes 35-x gallons of gas
We can write
[tex]\Rightarrow 25x+15(35-x)=725\\\Rightarrow 25x-10x=725-525\\\Rightarrow 10x=200\\\Rightarrow x=20[/tex]
First consumed 20 gallons and second consumed 15 gallons
