The sum of the polynomial is equal to -10x^3 + 2x^2 + 7x + 8.
what are polynomials?In mathematics, polynomials refers to an algebraic equation which have more than two terms, the terms are usually same variable but the exponents tends to increase the number of terms.
An algebraic equation with the highest power as two is generally called parabolic equation/ When the power goes above two they are called polynomial.
How to add polynomialsaddition of polynomials is achieved by adding like terms together. the like terms as in the question include similar alphabet and same exponents
( -4x^3 + 10x^2 + 6 ) - ( 6x^3 + 8x^2 - 7x - 2 )
terms with x^3: -4 - 6 = -10
terms with x^2: 10 - 8 = 2
terms with x: 0 - ( - 7 ) = 0 + 7 = 7
constant terms : 6 - ( - 2 ) = 6 + 2 = 8
constant terms refers to terms that does not have x
writing the equation together with their terms gives -10x^3 + 2x^2 + 7x + 8. Hence we can conclude that addition of polynomials involves addition performed considering the terms by adding like term.

a. A circle contains the points (0,0),(6,8) , and (7,7) . Find its equation by solving a system of three equations.
Answers
Using system of three equations, the equation of the circle that contains the points (0 , 0), (6 , 8), and (7 , 7) is (x - 3)^2 + (y - 4)^2 = 25.
The standard form of the equation of circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Substituting the values of the x and y coordinates of each point to the standard form of the equation of a circle, the three system of equations are:
(x - h)^2 + (y - k)^2 = r^2
(0 , 0) : (0 - h)^2 + (0 - k)^2 = r^2
(6 , 8) : (6 - h)^2 + (8 - k)^2 = r^2
(7 , 7) : (7 - h)^2 + (7 - k)^2 = r^2
Expanding these equations,
(0 , 0) : h^2 + k^2 = r^2 (equation 1)
(6 , 8) : 36 - 12h + h^2 + 64 - 16k + k^2 = r^2 (equation 2)
(7 , 7) : 49 - 14h + h^2 + 49 - 14k + k^2 = r^2 (equation 3)
Subtracting equation 1 from equation 2 and 3.
36 - 12h + h^2 + 64 - 16k + k^2 = r^2
- (h^2 + k^2 = r^2)
36 - 12h + 64 - 16k = 0
100 - 12h - 16k = 0
12h + 16k = 100
Dividing both sides by 4,
3h + 4k = 25 (equation 4)
49 - 14h + h^2 + 49 - 14k + k^2 = r^2
- (h^2 + k^2 = r^2)
49 - 14h + 49 - 14k = 0
98 - 14h - 14k = 0
14h - 14k = 98
h + k = 4 (equation 5)
h = 7 - k
Substitute h = 7 - k to equation 4 and solve for k.
3h + 4k = 25 (equation 4)
3(7 - k) + 4k = 25
21 - 3k + 4k = 25
k = 25 - 21
k = 4
Substitute the value of k to equation 5 and solve for h.
h = 7 - k (equation 5)
h = 7 - 4
h = 3
Substitute the value of h and k to equation 1 and solve for r.
h^2 + k^2 = r^2 (equation 1)
3^2 + 4^2 = r^2
9 + 16 = r^2
r^2 = 25
r = 5
Hence, the equation of the circle that contains the points (0 , 0), (6 , 8), and (7 , 7) is (x - 3)^2 + (y - 4)^2 = 25.

a) n(n+2)> with a line under 76
b) n(n+1)>76
c) n(n+1)<76
d) n(n+2)<76
Answers
The two consecutive odd integers are less than 76 is the numbers are 37 and 39.
Any integer's reverse and sum are both equal to zero.
A positive sum results from adding two positive numbers, whereas a negative sum results from adding two negative integers.
Take the absolute value of each integer, then subtraction, to obtain the total of a positive and a negative integer.
Let two consecutive odd numbers be x and x+2
According to question
⇒ x........... equation (1)
⇒ x+2........equation (2)
by adding equation 1 and 2
⇒ x+x+2=76
⇒ 2x+2=76
⇒ 2x=76-2
⇒ 2x=74
⇒ x=74/2
⇒ x=37
We apply the value of x=37 in equation (2)
⇒ x+2
⇒ 37+2
⇒ 39
so, the numbers are 37 and 39.
Therefore, the two consecutive odd integers are less than 76 is the numbers are 37 and 39

Find the measures of the sides of ΔX Y Z and classify
triangle by its sides.
X(-4,-2), Y(-3,7), Z(4,-2)
Answers
The measures of the sides of ΔXYZ are XY = 9.1, YZ = 11.4, XZ = 8. and the triangle XYZ must be an acute triangle
In this questions we have been given the the coordinates of the triangle XYZ.
X(-4, -2), Y(-3, 7), Z(4, -2)
We need to find the measures of the sides of ΔXYZ .
We find the the measures of the sides using distance formula.
XY = √[(7 + 2)² + (-3 + 4)²]
XY = √[9² + 1²]
XY = √(81 + 1)
XY = √(82)
XY = 9.1
Now side YZ
YZ = √[(-2 - 7)² + (4 + 3)²]
YZ = √[(-9)² + (7)²]
YZ = √81 + 49
YZ = √130
YZ = 11.4
And the length of side XZ would be,
XZ = √[(-2 + 2)² + (4 + 4)²]
XZ = √0 + 8²
XZ = 8
We find the sum of the squares of the two smaller sides, and compare the sum to the square of the largest side.
the sum of the squares of the two smaller sides is,
= 8² + 9.1²
= 64 + 82.81
= 146.81
= 12.12²
And 11.4² = 129.96
Since the sum of the squares of the two smaller sides is greater than the square of the largest side, the triangle must be an acute triangle.
Therefore, the measures of the sides of ΔXYZ are XY = 9.1, YZ = 11.4, XZ = 8. and the triangle XYZ must be an acute triangle

(a) On what date will the fish population again be the same as on January 1, 2002? (b) By what date will all the fish in the lake have died?
Answers
The fish population will be the same as on January 1, 2002 on January 1, 2017 and all the fish in the lake will have died by 2019
(a) On what date will the fish population again be the same as on January 1, 2002?The function is given as:
F(t) = 1000(30 + 15t - t^2)
Start by calculating F(0) --- population in 2002
So, we have:
F(0) = 1000(30 + 15(0) - 0^2)
F(0) = 30000
Substitute 30000 for F(t) in F(t) = 1000(30 + 15t - t^2)
1000(30 + 15t - t^2) = 30000
Divide by 1000
30 + 15t - t^2 = 30
Simplify
t^2 - 15t = 0
Divide through by t
t - 15 = 0
Solve
t = 15
This means that
Year = 2002 + 15
Year = 2017
Hence, the fish population will be the same as on January 1, 2002 on January 1, 2017
(b) By what date will all the fish in the lake have died?This means that F(t)= 0
So, we have:
1000(30 + 15t - t^2) = 0
Divide by 1000
30 + 15t - t^2 = 0
Rewrite as
t^2 - 15t - 30 = 0
Using a graphing calculator, we have
t = 17 (approximated)
This means that
Year = 2002 + 17
Year = 2019
Hence, all the fish in the lake will have died by 2019

The equation of the line, with slope equal to 0 and passing through the point located at (4 , -2), is y = -2.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the point slope form, plug in the values to set up the equation.
(y - y1) = m(x - x1)

Max is building a set of shelves. he buys a board that is 4 yards long. he wants to cut as many pieces of board that are 3/4 yard long as he can. how many pieces can he cut? will he have any board left over? if so how much?
Answers
If Max is building a set of shelves and he buys a board that is 4 yards long and he wants to cut as many pieces of board that are 3/4 yards long as he can, then the no of pieces he can cut is 5 and he will have 0.25 yards of board left over.
3/4 is a fraction which can be represented as,
3/4 = 0.75
The number of pieces of board that Max can cut that is 4 yards long can be determined by the division of the length of the board by the length of the cut pieces. Therefore,
number of pieces cut = length of the board ÷ length of a cut piece
number of pieces cut = 4 ÷ 0.75
number of pieces cut = 5.33, that is round off to 5
Thus he can cut 5 pieces of 3/4 yards.
As 5 × 3/4 = 3.75 yards
The remaining yards of the board can be calculated by subtraction.
Board leftover = 4 - 3.75 = 0.25 yards
Hence, Max can cut 5 pieces of 3/4 yards and will have 0.25 yards of the board left over.

Sam figures that he also earns about $2.50 in tips for each person he serves.
Sam works 4 hours on a particular day.
If n represents the number of people Sam serves that day, which of the
following functions could Sam use to figure E, his total earnings for the day?
An+ 10
Answers
Option c is the correct answer. Sam's total earning for the day is equal to
E(n) = 2.5n + 24
Given data
Sam earning per hour = $6
Sam earning on tips per person = $2.5
Sam's total hour per day =4
How to find the function for Sam's total earningsSam's daily earning excluding tips = Sam earning per hour * Sam's total hour per day
= $6 * 4 hours = $24
If n represents the number of people Sam serves that day, then Sam's earnings on tips in a day = $2.5 * n = $2.5n
The function for Sam's total earning is given by E(n)
E(n) = Sam's daily earning excluding tips + Sam's earnings on tips in a day
E(n) = $24 + $2.5n
this is re arranged as
E(n) = 2.5n + 24
