Answer:
f(x) = 3x³ +6x² -3x -6
Step-by-step explanation:
Each x-intercept (x=p) gives rise to a factor (x-p), so the factored form of the function is ...
f(x) = a(x -(-2))(x -(-1))(x -1)
The value of 'a' is chosen to make the y-intercept match that shown. The function just written has ...
f(0) = -6 = a(2)(1)(-1)
-6 = -2a
a = 3 . . . . . divide by -2
So, the function in factored form is ...
f(x) = 3(x +2)(x +1)(x -1)
Expanded, this is ...
f(x) = 3x³ +6x² -3x -6

Which of these figures has rotational symmetry?
12.6% of
RI 149 390bn
Answer: RI 18,823.14
Step-by-step explanation:
I guess that we want to find the 12.6% of Rl 149,390
First, we assume that Rl 149,390 is the 100%
Then we can write an equation like:
Rl 149,390 = 100%
Then if the amount X is the 12.6%, we also have the equation:
X = 12.6%
Then we have the two equations:
X = 12.6%
Rl 149,390 = 100%
If we take the quotient between these two equations we get:
(X/Rl 149,390) = (12.6%/100%)
Solving this for X we get:
X = (12.6%/100%)*(Rl 149,390) = RI 18,823.14
8 6/7 =
i want it in fraction form and in the smallest form.
Answer:
[tex]8\frac{6}{7}[/tex] as an improper fraction is [tex]\frac{62}{7\\}[/tex]
[tex]8\frac{6}{7}[/tex] in simplest form is [tex]8 \frac{6}{7\\}[/tex]
Step-by-step explanation:
To find the improper fraction of 8 6/7 is:
Multiply the denominator of the fraction by the whole number, 8. This gives you 56. Now, add the 56 with the numerator of the fraction. This gives you 62 as a sum. So, the improper fraction is 62/7.
You cannot simplify 8 6/7 because it is in simplest form.
A triangle has side lengths of 14 cm and 7 cm. Which could be the value of the third side, 22 cm or 20 cm?
Answer:
Undefined, it can be 20 cm, 22 cm or any value.A triangle has no limitations for any of each three sides.
Step-by-step explanation:
How it works? The triangles have no limits on their sides, but by their angles. Each triangle sums 180 degrees at the inner angles. If you don't have specific values for the angles it is not necessary to get some values for the third side. It could be 1, 2, .... or even 1000.

Lashawna is making jewelry to sell at a craft fair. On Monday, she makes 12 bracelets. On Tuesday, she works an additional 2.5 hours and has a total of 22 bracelets. Determine the time it takes Lashawna to make one bracelet
Answer:
ok, so she made 10 bracelets in 2.5 hours. 22-12= 10
2.5 ÷10= .25 hours per bracelet
an hour is 60 minutes, so .25 x60= 15 minutes per bracelet

What is length of PR
m PZR is 2/3 pie radius
Answer:
Option (4)
Step-by-step explanation:
m(∠PZR) = [tex]\frac{2}{3}\pi[/tex]
Radius of the circle = 8
Since, length of an arc = [tex]\frac{\theta}{2\pi }(2\pi r)[/tex]
Here, θ = Central angle in radians
From the given formula,
m(arc PR) = [tex]\frac{\frac{2}{3}\pi}{2\pi }(2\pi \times 8)[/tex]
= [tex]\frac{2}{6}(16\pi )[/tex]
= [tex]\frac{16}{3}\pi[/tex]
Therefore, Option (4) will be the correct option.

a person types 360 words in 4 minutes how much times does he take to types 900 words?
Answer:
10
Step-by-step explanation:
360*2 = 720. That leaves 180 words.
360/2 = 180
half the words would take half the time
4/2 = 2
8+2 = 10
Kaley reads 6 graphic nwels fewer than Safara.
Daniel reads 3 times as many as Kaley.
Daniel reads 30 graphic novels.
a. How many graphic novels does Safara read?
Show your work.
Answer: 16
Step-by-step explanation:
We first find out the number of graphic novels that Kaley reads, we set the number as k.
3k = 30
k = 10
Then Kaley reads 6 graphic novels fewer than Safara, which means that we plus 6 to the number of graphic novels that Kaley read,
k + 6 = 10 + 6 =16
Safara read 84 graphic novels.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. The fundamental ideas in number theory, measurement, and computation are frequently referred to as arithmetic (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).
As per the given data:
Kaley reads 6 graphic novels fewer than Safara ...(i)
Daniel reads 3 times as many as Kaley ...(ii)
Graphic novels Daniel read = 30
Kaley read = 3 × 30 = 90 novels {from statement (ii)}
Safara read = 90 - 6 = 84 novels {from statement (i)}
Hence, Safara read 84 graphic novels.

Write an equation of a line in slope intercept form that passes through (6,5) 1 poi
and is parallel to y =-X+4 *
Answer:
y = -x + 11
Step-by-step explanation:
The slope of the line y = -x + 4 is -1.
So the slope of our line is also -1 ( because they are parallel).
First use the point-slope form of the equation of a line:
y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line.
Here m = -1 and (x1, y1) = (6, 5).
So we have:
y - 5 = -1(x - 6)
y - 5 = -x + 6
y = -x + 11 <------ Slope intercept form.
