write a polynomial function in standard form with the given zeros x=1,-1,-2
Answer:
y = x³ +2x² -x -2
Step-by-step explanation:
A polynomial with root q has a factor (x -q). The factored form of the polynomial is ...
y = (x -1)(x +1)(x +2)
y = (x² -1)(x +2) . . . . . . partial simplification
y = x³ +2x² -x -2

Explanation:
Refer to the remote interior angle theorem (some books call it the exterior angle theorem). That says we can add the two interior angles and the sum is the exterior angle that is not adjacent to either interior angle.
(interiorAngle1) + (interiorAngle2) = exterior angle
(5x) + (2x+6) = 8x-11
7x+6 = 8x-11
6+11 = 8x-7x
17 = x
x = 17
----------------
Or the slightly longer method has you follow these steps:
y = missing interior angle in the upper right corner
The angle (8x-11) and angle y are supplementary
(8x-11) + (y) = 180
y = 180-(8x-11)
y = 180-8x+11
y = -8x+191
For any triangle, the three interior angles always add to 180
(angle1)+(angle2)+(angle3) = 180
(5x)+(2x+6)+(-8x+191) = 180
-x+197 = 180
-x = 180-197
-x = -17
x = 17

For triangle MNO, the statements that are true are m ∠ MNP < m ∠ ONP and MP< OP.
We are given a triangle MNO.
We are also given that:
m ∠ MNP = 38°
m ∠ ONP = 39°
This clearly means that:
m ∠ MNP < m ∠ ONP
Also, since m ∠ MNP < m ∠ ONP , the sides opposite to the angles will also follow the same relationship.
Side opposite to ∠ MNP is MP
and side opposite to ∠ ONP is OP
so, the relation will become:
MP < OP
Therefore, we get that, for triangle MNO, the statements that are true are m ∠ MNP < m ∠ ONP and MP< OP.

The statements m MNP m ONP and MP < OP are true for triangle MNO.
A triangle MNO is presented to us.
Additionally, we learn that
m ∠ MNP = 38°
m ∠ ONP = 39°
This demonstrates that:
m, MNP, m, and ONP
The sides that are opposite to the angles will also adhere to the same relationship because m MNP m ONP.
MP is the side that faces MNP.
and OP is the side opposite to ONP.
hence, the relationship will be:
MP < OP
As a result, we understand that for triangle MNO, the assertions m MNP m ONP and MP OP are true.

Mr. Lamb is missing a solution for his next patient. He has a cylindrical test tube which is 4 cm across the inside. The depth of the tube is 9 cm. What is the volume of the cylinder in mL?
Answer:
V=113.04mL
Step-by-step explanation:
The question is asking us to find the volume of a cylinder in mL. For this, we can use the equation V=[tex]\pi r^{2} h[/tex].
We know the diameter, 4cm, and the height, 9cm.
In order to solve, we must first find the radius.
r=1/2d
r=1/2(4)
r=2cm
We can now plug this into our equation.
V=[tex]\pi r^{2} h[/tex]
V=[tex]\pi (2)^{2} (9)[/tex]
V=[tex](3.14)(2)^{2} (9)[/tex]
V=113.04mL
Solve the system of equations
X=11+y
2x+y=19
Answer:
Step-by-step explanation:
To solve this system of equations, let's first find the value y. We can replace the x in the second equation with 11 + y, since we are told in the first equation that x is equal to 11 + y. So, let's replace x:
2(11 + y) + y = 19
22 + 2y + y = 19
22 + 3y = 19
3y = -3
y = -1
And look at that - we've found our y-value! Now, we can replace the y in the first equation with -1 to find the value of x.
x = 11 + (-1)
x = 10
So, the solution to this system of equations is (10, -1). Hopefully that's helpful!

Anna and Hannah are reading the same book. At the beginning of the month, Anna was on page 29 and Hannah was on page 7. Anna will read 9 pages per day and Hannah will read 11 pages per day. Let

H
H represent the page of the book that Hannah is on at the end of
t
t days into the month. Write an equation for each situation, in terms of
t
,
t, and determine whether Anna or Hannah is farther along in the book after 14 days.
Answer:
Hannah
Step-by-step explanation:
Anna: Page 29 + number of pages read t days into the month
number of pages read t days in the month = 9 t times = 9 * t
Anna: 29 + 9t
Hannah: 7 + 11t using the same logic
14 days in: t = 14
Anna: 29 + 9*14 = 155
Hannah: 7 + 11 * 14 = 161
Hannah is further along
The equations for Anna's progress A = 29 + 9t and Hannah's progress H = 7 + 11t show that after 14 days, Hannah is farther along in the book with page 161 compared to Anna's page 155.
How to Apply Algebraic Equation?The equation we would write for each situation in terms of t are explained below:
For Anna:
A = 29 + 9t
For Hannah:
H = 7 + 11t
After 14 days:
For Anna: A = 29 + 9 * 14 = 29 + 126 = 155
For Hannah: H = 7 + 11 * 14 = 7 + 154 = 161
After 14 days, Hannah is farther along in the book as she is on page 161 while Anna is on page 155.
