The product of [tex]-2x^{3}[/tex] + x - 5 and [tex]x^{3}[/tex] - 3x - 4 is [tex]-2x^{6}[/tex] + [tex]7x^{4}[/tex] + [tex]3x^{3}[/tex] + [tex]12x^{2}[/tex] - 4x + 20. The order of the polynomials does not affect the result; they yield the same product.
a) To find the product of [tex]-2x^{3}[/tex] + x - 5 and [tex]x^{3}[/tex] - 3x - 4, we multiply each term in the first expression by each term in the second expression and combine like terms.
[tex]-2x^{3}[/tex] * [tex]x^{3}[/tex] = -2[tex]x^{6}[/tex]
[tex]-2x^{3}[/tex] * (-3x) = 6[tex]x^{4}[/tex]
[tex]-2x^{3}[/tex] * (-4) = 8[tex]x^{3}[/tex]
x * [tex]x^{3}[/tex] = [tex]x^{4}[/tex]
x * (-3x) = -3[tex]x^{2}[/tex]
x * (-4) = -4x
-5 * [tex]x^{3}[/tex] = -5[tex]x^{3}[/tex]
-5 * (-3x) = 15[tex]x^{2}[/tex]
-5 * (-4) = 20
Combining all the terms, we have:
-2[tex]x^{6}[/tex] + 6[tex]x^{4}[/tex] + 8[tex]x^{3}[/tex] + [tex]x^{4}[/tex] - 3[tex]x^{2}[/tex] - 4x - 5[tex]x^{3}[/tex] + 15[tex]x^{2}[/tex] + 20
Simplifying further:
-2[tex]x^{6}[/tex]+ 7[tex]x^{4}[/tex] + 3[tex]x^{3}[/tex] + 12[tex]x^{2}[/tex] - 4x + 20
Therefore, the product of -2[tex]x^{3}[/tex] + x - 5 and [tex]x^{3}[/tex] - 3x - 4 is -2[tex]x^{6}[/tex] + 7[tex]x^{4}[/tex] + 3[tex]x^{3}[/tex] + 12[tex]x^{2}[/tex] - 4x + 20.
(b) The product of two polynomials is commutative, which means that changing the order of the polynomials being multiplied does not affect the result. In other words, the product of [tex]x^{3}[/tex] - 3x - 4 and -2[tex]x^{3}[/tex] + x - 5 will be the same as the product obtained in part (a).
Therefore, the product of -2[tex]x^{3}[/tex] + x - 5 and [tex]x^{3}[/tex] - 3x - 4 is equal to the product of [tex]x^{3}[/tex] - 3x - 4 and -2[tex]x^{3}[/tex] + x - 5. The order of the polynomials being multiplied does not impact the final result, so both expressions yield the same product.

Step-by-step explanation:
ok first you have to find the hypotenuse of the smaller triangle
a²+b²=c²
2²+4²=c²
4+16=20
√20≈ 4.5
4.5²+7²=c²
20.25+49≈ 69.25
√69.25≈ 8.3
Answer:
x = [tex]\sqrt{69}[/tex]
Step-by-step explanation:
Pythagorean theorem: A^2 + B^2 = C^2
first, find the length of the line cutting through the shape:
let's call this line L.
plug the numbers into the theorem.
4^2 + 2^2 = L^2
16 + 4 = L^2
20 = L^2
next, plug 7 and L into the theorem again to find x
L^2 + 7^2 = x^2
20 + 49 = x^2
69 = x ^2
x = [tex]\sqrt{69}[/tex]
A steel bridge is 1000m lang at 20 degrees celsius. The bridge will expand or contract by .10m when the temperature changes by 1 degree celsius. How long would the bridge be at 24 degrees celsius? *
Answer:
1000.4m
Step-by-step explanation:
Objects usually expand when the temperature is warmer
Each degree celsius higher, the bridge expands by .10m
If the temperature goes from 20 to 24, it increases by 4 degrees which will be 0.4m
1000m+0.4m=1000.4m

find the equation of a line passing through the point(-3,0) and (2,-3)
Answer (assuming the question allows it to be written in slope-intercept form):
[tex]y = -\frac{3}{5} x-\frac{9}{5}[/tex]
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], substitute the given points' x and y values, and simplify:
[tex]m = \frac{(-3)-(0)}{(2)-(-3)} \\m =\frac{-3-0}{2+3}\\m = -\frac{3}{5}[/tex]
Thus, the slope is [tex]-\frac{3}{5}[/tex].
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{3}{5}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:
[tex]y-(-3) = -\frac{3}{5} (x-(2))\\y + 3 = -\frac{3}{5} x + \frac{6}{5} \\y = -\frac{3}{5} x - \frac{9}{5}[/tex]
Answer:
y = -3

Martina bought 4 CDs that were each the same price. Including sales tax, she paid a total of $70.40 . Each CD had a tax of $ 1.10 . What was the price of each CD before tax?
[tex]1.10 \times 4 = 4.40[/tex]
[tex]70.40 - 4.40 = 66[/tex]
[tex]66 \div 4 = 16.5[/tex]
Each CD was $16.50 before tax
Proof
[tex]total \: cost = 16.5(4) + 1.10(4)[/tex]
[tex]total \: cost = 66 + 4.40[/tex]
[tex]total \: cost = 70.40[/tex]

Jennifer is four less than three times Toby's age. If Jennifer is 23, then how old is Toby? equation: solution:
Answer:
T = Toby
T=(23+4)/3
Step-by-step explanation:
If Jennifer’s age is 4 less than 3 times Toby’s age then Jennifer’s age by three,
T=(23+4)/3
and 3 times that, so we divide
T=(23+4)/3
Then Toby is 9 years of age, and shouldn’t be driving.

Uptown towing company charges $60 to tow a car plus $25 per day for vehicle storage. Downtown Towing company charges $75 for towing plus $20 per day for vehicle storage. Write the two equations for the companies
Answer:
Uptown towing company: 60 + 25d
Downtown towing company: 75 + 20d
Step-by-step explanation:
Uptown towing company: 60 + 25d
Downtown towing company: 75 + 20d
Where d = number of days
60 + 25d
75 + 20d
Equate both equations
60 + 25d = 75 + 20d
60 - 75 = 20d - 25d
-15 = -5d
d = -15/-5
d = 3

determine if JK and LM parallel, perpendicular, or neither .
Answer:
3 - Perpendicular.
4 - Parallel.
Step-by-step explanation:
[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]JK = \frac{1-(-7)}{-4-(-10)} = \frac{8}{6} = \frac{4}{3}[/tex]
[tex]LM = \frac{-2-2}{-6-(-3)} = \frac{-4}{3}[/tex]
Perpendicular, because two lines are considered perpendicular if their slopes are opposite reciprocals.
[tex]JK = \frac{-2-(-2)}{3-11} = \frac{0}{-8} = 0[/tex]
[tex]LM = \frac{-2-(-7)}{1-1} = \frac{5}{0} = 0[/tex]

Consider points a, b, and c in the graph. Determine which of these points is relative minima on the interval x = –1 and x = –2 in the graph.
Options:
1.)B
2.)A and B
3.)C
4.)A
Answer:
as we can see here point {\color{Red}a} lies on the interval (-2, -1)
so option A is correct
Step-by-step explanation:
The required minima on the graph in the interval x = -1 and x = -2 is A. Option 4) is correct.
Given that,
A Curve is shown on the graph,
In the interval of x = -1 and x = -2, relative minima is to be determined.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Since,
A minimum of the curve it that point where the slope of the curve is zero and at that point where the slope is zero the neighboring values must be greater to the point on the curve.
So point a is required minima where the slope is zero and also neighboring values are greater than a
Thus, the required minima on the graph in the interval x = -1 and x = -2 is A. Option 4) is correct.
