The graph of a function gives the set of a ordered pair of the function
Pease find attached and included the appearance of the graph and table of values of the given function f(x) = 2·x³ - 7·x² + 2·x + 3
The given function is presented as follows;
f(x) = 2·x³ - 7·x² + 2·x + 3
Required:
To find the graph that represents the given function
Solution:
From the given function, at x = 0, we have;
f(0) = 2 × 0³ - 7×0² + 2×0 + 3 = 3
Therefore, at x = 0, f(x) = 3, and a point on the graph is the point (0, 3)
At x = 1, f(x) = 2 × 1³ - 7×1² + 2×1 + 3 = 0 therefore, a graph point is (1, 0)
At x = 0.5, f(x) = 2 × 0.5³ - 7×0.5² + 2×0.5 + 3 = 2.5 therefore, a graph point is (0.5, 2.5)
With the above function, the following table can be obtained
[tex]\begin{array}{|c|cc|}\mathbf{x}&&\mathbf{y}\\-1&&-8\\-0.5&&0\\0&&3\\0.5&&2.5\\1&&0\\1.5&&-3\\2&&-5\\2.5&&-4.5\\3&&0\\3.5&&10\end{array}\right][/tex]
From the above table of values, the graph of the function can be drawn as shown in the attached diagram created with MS Excel

Jina, Chang, and Kevin sent a total of 130 text messages over their cell phones during the weekend. Chang sent 3 times as many messages as Kevin.
Kevin sent 5 fewer messages than Jina. How many messages did they each send?
Answers
Answer:
Let the no. of messages Jina send be x.
No. of messages Kevin send=x-5
No. of messages Chang send=3(x-5)
=3x-15
x+(x-5)+(3x-15)=130
x+x-5+3x-15=130
x+x+3x-5-15=130
5x-20=130
5x=130+20
=150
x=150÷5
=30
No. of messages Jina sent=30
No. of messages Kevin sent=30-5
=25
No. of messages Chang sent=3(30)-15
=90-15
=75

then it will be 15 x equals to 30 + 50 and then then 15 x equals to 8 and then you divide both of the sides with 15 then get your answer
-5 (-3x+10)=30
15x-50=30

Adult humans have approximately 2.6 x 10 red blood cells and 3.92 x 10 white blood cells about how many times greater is the number of red blood cells than white blood cells
Answers
Answer:
The number of red blood cells is approximately [tex]660[/tex] times greater than white blood cells.
Step-by-step explanation:
Given:
Red blood cells [tex]$2.6 \times 10^{6} / \mathrm{mm}^{3}=2.600 .000 \times \mathrm{mm}^{3}$[/tex] White blood cells [tex]$3.92 \times 10^{3} / \mathrm{mm}^{3}=3.920 \times \mathrm{mm}^{3}$[/tex]To find how many times greater is the number of red blood cells than white blood cells
Divide the amount of the former between the second
[tex]=\frac{2,600.000}{3,920}[/tex]
[tex]=663.27[/tex]
≈ [tex]660[/tex]
Therefore, number of red blood cells is approximately [tex]660[/tex] times greater than white blood cells.

a square room has an area of 200 square feet. how long is each wall? show your work to explain why
Answers
Answer:
about 14.142ft
Step-by-step explanation:
A square has four equal sides.
The area of a square: length * width = area
Because you know that all of the sides are equal, you can just say:
length * length = area
Multiplying a value (in this case, length) by itself is the same thing as squaring it. So, you can simplify the equation further by writing:
length² = area
Fill in what you know:
length² = 200ft²
Now, work the problem backwards by taking the square root of 200 to find the length:
√length² = √200ft²
length = 14.142ft
So, each wall is 14.142ft long
You can test this by working the problem in reverse:
14.142ft * 14.142ft ≈ 200ft²

~AH1807Peace!Step-by-step explanation:
Given that:
x = 4-√17
Therefore, 1/x = 1/(4-√17)
Now, the denominator is 4-√17
We know that
Rationalising factor of a-√bc is a+√bc.
Therefore, the rationalising factor of 4-√17 is 4+√17.
On rationalising the denominator them
⇛[1/(4-√17)]×[(4+√17)/4+√17)]
⇛[1(4+√17)]/[(4-√17)(4+√17)]
Since, (a-b)(a+b) = a²-b²
Where,
a = 4 and b = √17⇛[1(4+√17)]/[(4)²-(√17)²]
⇛[1(4+√17)]/(4*4)-√(17*17)]
⇛[4+√17]/[16 - 17]
⇛(4+√17)/1
⇛1/x = 4+√17 ans.

Answers
Answer:
(3 x - 1) (3 x + 8)
Step-by-step explanation:
Factor the following:
9 x^2 + 21 x - 8
Factor the quadratic 9 x^2 + 21 x - 8. The coefficient of x^2 is 9 and the constant term is -8. The product of 9 and -8 is -72. The factors of -72 which sum to 21 are -3 and 24. So 9 x^2 + 21 x - 8 = 9 x^2 + 24 x - 3 x - 8 = 8 (3 x - 1) + 3 x (3 x - 1):
8 (3 x - 1) + 3 x (3 x - 1)
Factor 3 x - 1 from 8 (3 x - 1) + 3 x (3 x - 1):
Answer: (3 x - 1) (3 x + 8)
