What is the simplified form of the following expression? (y8)(y2) y10 y6 y16 y64
Answers
The simplified form of the expression (y^8)(y^2) is y^10, found by applying the laws of exponents that dictate adding the exponents when multiplying with the same base.
Explanation:The simplified form of the expression (y8)(y2) can be found using the laws of exponents which state that when multiplying two powers with the same base, you add the exponents. Here, since the base is y, and we have exponents 8 and 2, we add them together:
y8 × y2 = y8+2
This simplifies to y10, which is the compressed form of the given expression.
Final answer:
To simplify the expression (y⁸)(y²), use the rule of exponents which says that you add the exponents when multiplying powers with the same base, resulting in y¹⁰.
Explanation:
The question requires simplifying an algebraic expression with exponents. The given expression is (y⁸)(y²). To simplify this, we use the rule of exponents which states that when multiplying two powers with the same base, you add the exponents. Therefore, y⁸ × y² = y⁸₊²} = y¹⁰

The area of a rectangle is 440 square inches. The length of the rectangle is 29 inches more than its width. What is the length of the rectangle?
Answers
the length of the rectangle is either -11 inches or 40 inches.
Let the length of the rectangle be L.Let the width of the rectangle be W.Given the following data;
Area of rectangle = 440 square inchesTranslating the word problem into an algebraic equation, we have;
[tex]L = W + 29[/tex]
To find the length of the rectangle;
Mathematically, the area of a rectangle is given by the formula;
[tex]Area = L * W[/tex]
Substituting the values into the formula, we have;
[tex]440 = (W + 29) * W\\\\440 = W^{2} + 29W[/tex]
Rearranging the equation, we have;
[tex]W^{2} + 29W - 440 = 0[/tex]
W e would solve the quadratic equation by factorization;
[tex]W^{2} + 40W - 11W - 440 = 0\\\\W(W + 40) - 11(W + 40)\\\\(W + 40)(W- 11)[/tex]
Width, W = -40 0r 11 inches.
Next, we would find the length of the rectangle;
When Width, W = -40;
[tex]L = W + 29[/tex]
[tex]L = -40 + 29[/tex]
Length, L = -11 inches
When Width, W = 11;
[tex]L = W + 29[/tex]
[tex]L = 11 + 29[/tex]
Length, L = 40 inches
Therefore, the length of the rectangle is either -11 inches or 40 inches.

What value of c makes the statement true? -2x3(cx3 + x2) = -10x6 - 2x5
Answers
c would have to be 5....because -2x^3(5x^3) = -10x^6
Answer: The required value of c that makes the given statement true is 5.
Step-by-step explanation: We are given to find the value of c that makes the following statement TRUE :
[tex]-2x^3(cx^3+x^2)=-10x^6-2x^5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To find the value of c, we need to equate the coefficients of the same powers of the unknown variable x.
From equation (i), we have
[tex]-2x^3(cx^3+x^2)=-10x^6-2x^5\\\\\Rightarrow -2cx^{3+3}-2x^{3+2}=-10x^6-2x^5\\\\\Rightarrow -2cx^6-2x^5=-10x^6-2x^5.[/tex]
Equating the coefficients of [tex]x^6[/tex] on both sides of the above equation, we get
[tex]-2c=-10\\\\\Rightarrow c=\dfrac{-10}{-2}\\\\\Rightarrow c=5.[/tex]
Thus, the required value of c that makes the given statement true is 5.

Matt is five years older than twice his cousin Andy’s age. The sum of their ages is less than 35. Let x represent Andy's age.
Answers
Final answer:
To represent the relationship between Matt and Andy's ages mathematically, let x be Andy's age, and express Matt's age as 2x + 5. The inequality x + (2x + 5) < 35 simplifies to x < 10, indicating Andy's age must be less than 10.
Explanation:
The question involves creating an inequality to represent the relationship between Matt and Andy's ages, where Matt is five years older than twice Andy's age, and the sum of their ages is less than 35.
Let x represent Andy's age. The formula for Matt's age would be 2x + 5. To find the range of possible values for Andy's age, you would write the inequality x + (2x + 5) < 35.
Solving this inequality involves combining like terms and isolating the variable x.
Step 1: Combine like terms.
x + 2x + 5 < 35
Step 2: Simplify the inequality.
3x + 5 < 35
Step 3: Subtract 5 from both sides to isolate the term with x.
3x < 30
Step 4: Divide both sides by 3 to solve for x.
x < 10
This tells us that Andy's age must be less than 10 for the conditions to be met.
What is 1/12 (12-v)=1/6(v-6)
Answers
So, step one we would have solve from the same value
[tex] \frac{1}{12}(12-v) = \frac{1}{6}(v-6)\\ \frac{1}{12}(12) + \frac{1}{12} (-v) = \frac{1}{6}(v)+ \frac{1}{6} (-6) \\ 1 + \frac{-1}{12}(v) = \frac{1}{6}v + -01 \\ \frac{-1}{12} (v) +1 = \frac{1}{6} - 1 [/tex]
Step two we have to subtract by [tex] \frac{1}{6}v[/tex] on each of your sides (so it can kind of be easier for you to solve)
So,[tex] \frac{1}{6} v + 1 - \frac{1}{6}v = \frac{1}{6}v - 1 \frac{1}{6}v [/tex]
You would have to cancel out the right side because it would give you a(n) answer of 1
Now that we got those steps out of your way, let's subtract 1 to your sides that we're working with
[tex] \frac{-1}{4}(v) +1 -1 \\ = -1 -1 [/tex]
Finally we're close to our answer for [tex]v[/tex]
[tex] \frac{-1}{4}(v)= 2 [/tex]
[tex] \frac{4}{1} ( \frac{-1}{4} )[/tex] cancel this out because it gives you one
But, keep: [tex] \frac{4}{1} (-2)[/tex] because it gives you the answer
[tex]v = 8 [/tex]

Find the middle term of ([tex]( x^{2}+2) ^{20}
[/tex]
Answers
now, the middle guy in 21 terms, will be the 11th term.
using the binomial theorem, is simple to get the terms themselves, since all we're doing is, beginning at the highest with first element and going down by 1 each term, and with the second starting at 0 and going up, surely you already know that.
So, all that's left is what the dickens is the coefficient of each term in the expansion?
well, is "the current coefficient, times the exponent of the 1st element, divided all that by the exponent of the 2nd element on the next term", now, that's a mouthful but lemme post quick and explain a couple.
[tex]\bf (x^2+2)^{20}\implies \begin{array}{llll} term&coefficient&value\\ -----&-----&-----\\ 1&&(x^2)^{20}(+2)^0\\ 2&+20&(x^2)^{19}(+2)^1\\ 3&+190&(x^2)^{18}(+2)^2\\ 4&+1140&(x^2)^{17}(+2)^3\\ 5&+4845&(x^2)^{16}(+2)^4\\ 6&+15504&(x^2)^{15}(+2)^5\\ 7&+38760&(x^2)^{14}(+2)^6\\ 8&+77520&(x^2)^{13}(+2)^7\\ 9&+125970&(x^2)^{12}(+2)^8\\ 10&+167960&(x^2)^{11}(+2)^9\\ 11&+184756&(x^2)^{10}(+2)^{10}\\ \end{array}[/tex]
so, how did we get the coefficient for say the 5th term, the coefficient of 4845? well, is just 1140 * 17 / 4.
and how about the 6th term with 15504? well 4845 * 16 / 5.
another example, say the 10th term's coefficient of 167960? well is just 125970 * 12 / 9.
and now simply expand and combine the factors for the 11th term.

Two complementary angles are expressed as 4x - 16 and 2x 10. find the number of degrees in each angle.
Answers
angle 2 = 2x + 10
4x - 16 + 2x + 10 = 90
combine like terms
6x - 6 = 90
add 6 to both sides
6x = 96
divide both sides by 6
x = 16
angle 1 = 4x - 16 = 4(16) - 16 = 48
angle 2 = 2x + 10 = 2(16) + 10 = 42
Two complementary angles are given as 4x - 16 and 2x + 10. Solving for x we find x = 16. Substituting x into the expressions for the angles, we find the angles to be 48 and 42 degrees.
Explanation:The task here is to find the value of two angles that are complementary. Given the expressions for the angles are 4x - 16 and 2x + 10. As complementary angles, they sum up to 90 degrees. Hence, mathematically, we can express this as (4x - 16) + (2x + 10) = 90.
Solving the equation, combine like terms to get 6x - 6 = 90. Then, add 6 to both sides to get 6x = 96. Divide each side by 6 to find x, hence x = 16.
Substitute x = 16 into 4x - 16, therefore the first angle is 4×16 - 16 = 48 degrees. Similarly, substitute x = 16 into 2x + 10, hence the second angle is 2×16 + 10 = 42 degrees. The angles are thus 48 and 42 degrees, which adds up to 90).
