11) Which of the following is zero of the polynomial x^3+x^2+x+1
1
-1
both options 1 and 2
None
please answer
Answer:
Answer: -1
Step-by-step explanation:
The Polynomial Remainder Theorem
It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
We have the polynomial:
[tex]f(x)=x^3+x^2+x+1[/tex]
And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.
Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.
Find:
[tex]f(1)=1^3+1^2+1+1[/tex]
f(1)=4
Thus, x=1 is not a zero of f(x)
Now, find:
[tex]f(-1)=(-1)^3+(-1)^2+(-1)+1[/tex]
[tex]f(1)=-1+1-1+1=0[/tex]
Thus, x=-1 is a zero of f(x)

Shane and abha earned a team budget that required their team to collect no less than 2000 cans for recycling. Abha collected 178 more cans than Shane did. Write an inequality to determine the number of cans , s, that Shane could have collected
Answer:
s ≥ 911
Step-by-step explanation:
Let
s = number of cans Shane could collect
Abha collected 178 more cans than Shane did.
Abha = s + 178
Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling
Number of cans collected by Shane + number of cans collected by Abha ≥ 2000
s + 178 + s ≥ 2000
2s + 178 ≥ 2000
2s ≥ 2000 - 178
2s ≥ 1,822
Divide both sides by 2
s ≥ 1,822 / 2
s ≥ 911

The price of orange juice is believed to increase by 14% over the next year. If a gallon of orange juice costs $3.00 now, what will the price be in a year, after the increase?
$
$3.42
Take the original price and multiply by 1.14
Explanation: 1.14 comes from the whole (1) of the orange juice at the time plus the percent (14% ---> .14).

Write the equation of a line in slope-intercept and standard form.Given 1 point and a slope
Answer:
The equation of line is as follows:
Slope-intercept form: [tex]y = 7x-5[/tex]
Standard Form: [tex]-7x+y = -5[/tex]
Step-by-step explanation:
Given that
Slope of line: 7
Point : (1,2)
Slope-intercept form of equation of line is given by:
[tex]y = mx+b[/tex]
Here m is the slope and b is y-intercept.
Putting the value of slope
[tex]y = 7x+b[/tex]
To find the value of b, we have to put the point in the equation
[tex]2 = 7(1) +b\\2 = 7+b\\2-7 = b\\b = -5[/tex]
So the equation will be:
[tex]y=7x-5[/tex]
The standard form of equation of line is:
[tex]Ax+By = C[/tex]
To convert the equation in standard form, subtracting 7x from both sides
[tex]y-7x = 7x-5-7x\\-7x+y = -5[/tex]
Hence, the equation of line is as follows:
Slope-intercept form: [tex]y = 7x-5[/tex]
Standard Form: [tex]-7x+y = -5[/tex]
The equation of a line in slope-intercept and standard form through (1, 2), slope = 7 is 7x - y = 5.
To find the equation of a line in slope-intercept and standard form.
First, we can write the equation in point-slope form. The point-slope formula states:
(y − y₁) = m (x − x₁)
Where m is the slope and
(x1, y1) is a point the line passes through.
Substituting the values from the problem gives:
(y − 2) = 7(x − 1)
Now, we need to convert to standard form.
The standard form of a linear equation is:
Ax + By = C
where, if at all possible,
A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1
We convert as follows:
y − 2 = (7 × x) − (7 × 1)
y − 2 = 7x − 7
−7x + y − 2 = − 7
Adding 2 in both side.
−7x + y − 2 + 2 = − 7 +2
-7x + y = -5
7x - y = 5
Therefore, the equation of a line in slope-intercept and standard form is 7x - y = 5.

If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is not a 4? (Your answer must be in the form of a reduced fraction.)
Answer:
12/13
Step-by-step explanation:
A standard deck of cards has four suites
Total number of cards = 52
Total number of cards which are 4 is = 4
The probability that the card selected is 4 = 4/52 = 1/13
S, the probability that the selected card is not a 4 = 1 - (1/13 )= 12/13

The figure below is made up of a square with height, h, units and a right triangle with height, h units, and a base length, b units.
The area of this figure is 80 square units.
Write an equation for the area of the shape below.
Answer:
Step-by-step explanation:
A = 12 × 16 + (1/2)(12 + 8)(10) = 292 units²
The Equation for Area of figure is area of Figure, h² + 1/2(h)(b) = 80
What is Area?The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given:
We have the figure consist of one rectangle and one right triangle.
Now, Area of Figure,
=Area of rectangle + area of Triangle
= length x width + / x base x height
= 16 x 12 + 1/2 x 10 x 20
= 192+ 100
=292 unit²
and, if the square with height, h, units and a right triangle with height, h units, and a base length, b units.
Then, area of Figure= h² + 1/2(h)(b) = 80 square units.
