The width of the rectangle with area 70y⁸+ 30y⁶ is; 10y⁶.
Then the length of the rectangle with area 70y⁸+ 30y⁶ is; (7y² + 3).
What are the dimensions of the rectangle?
The area of a rectangle is given by;
Area = Length× width
Given that;
The area of the rectangle = 70y⁸ + 30y⁶
Now, 70y⁸ can be broken down to; 7×5×2×y×y×y×y×y×y×y×y
And 30y⁶ can be broken down to; 5×3×2×y×y×y×y×y×y
The common factors of 70y⁸ and 30y⁶ are = 5,2,y,y,y,y,y,y
Thus, the greatest common factor of 70y⁸ and 30y⁶ is;
5×2×y×y×y×y×y×y = 10y⁶
Therefore our area 70y⁸+ 30y⁶ can be factorized to get;
A = 10y⁶(7y² + 3)
The greatest common monomial of 70y⁸+ 30y⁶ is 10y⁶ which is the width of the rectangle.

The start of an arithmetic sequence is
17, 21, 25, 29,
21,
The rule for the sequence can be written in the form
In
= en + d, where c and d are numbers.
a) By first calculating the values of c and d, work out the rule
for the sequence.
b) What is the value of 211?
The equation of the sequence is xₙ = 4n + 17 and the 11th term is 61
The equation of the sequenceFrom the question, we have the sequence to be
17, 21, 25, 29, 21
The form of the sequence is given as
xₙ = cn + d
From the question, we have the first term to be 17
This means that
d = 17
So, we have
xₙ = cn + 17
When n = 1, we have x = 21
So, we have
21 = c + 17
Evaluate
c = 4
Substitute c = 4 in xₙ = cn + 17
xₙ = 4n + 17
The value of x₁₁This means that
n = 11
So, we have
x₁₁ = 4 * 11 + 17
Evaluate
x₁₁ = 61
Hence, the value is 61

60 cents as percent of $3
60 cents is 20% of $3.
What is the percentage?In essence, percentages are fractions with 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). The value of a number out of 100 is the percentage of that number. The terms "percent" and "cent" combine to make the word "percentage." Having Latin and French roots, the term "cent" means "hundred," while the word "percent" means "per hundred."
Given Data

For what value of x will the line passing through the following pairs of points be veritcal? F(3-2x, 12) and G(x+9, 7)
By solving a linear equation, we will see that the points are vertical only if the value of x is -2.
For which value of x are the points vertical?
We say that two points (x₁, y₁) and (x₂, y₂) are vertical if the points have the same x-component and different y-component, so we must have:
x₁ = x₂
y₁ ≠ y₂
In this case, the two points are:
F(3-2x, 12) and G(x+9, 7)
The y-component is different, so we only need to have:
3 - 2x = x + 9
This is a linear equation, below I will solve it:
3 - 2x = x + 9
3 - 9 = x + 2x
-6 = 3x

Ryan has a deck that measures 3 feet by 8 feet. He wants to increase each dimension
by equal lengths so that its area is increased by 50%. By how much should he increase each dimension?
The dimensions of the deck would be increased by 1 feet.
How much should he increase each dimension?Area of a rectangle = length x width
Initial area of the deck = 3 x 8 = 24 feet²
Area of the deck when it is increased = (1 + 0.50) x 24 = 36 feet²
Length of the deck after it is increased = 3 + x
Width of the deck after it is increased = 8+ x
Area of the new deck : (3 + x) + (8 + x) = 36
24 + 3x + 8x + x² = 36
x² + 8x + 3x + 24 - 36 = 0
x² + 11x - 12 = 0
The solutions of the quadratic equation are -1 and 12
-1 + x = 0
x = 1
or
12 + x = 0
x = -12
Thus, the dimension of the deck would be increase by 1 feet.

y = 2x² + 4x+1
A. (3,-4)
B. (-1,-1)
C. (1,7)
D. (-4,9)
The function has the vertex value of (-1, -1)
How to calculate the vertex of the function?From the question, the definition of the functuion is given as
y = 2x² + 4x + 1
Start by differentiating the function
This is done as follows
y' = 4x + 4
Next, we set the differentiated equation to 0
So, we have the following equation
4x + 4 = 0
This gives
4x = -4
Divide by 4
x = -1
Next, we substitute x = -1 in the given equation y = 2x² + 4x + 1
So, we have the following equation
y = 2(-1)² + 4(-1) + 1
Evaluate
y = -1
Recall that
x = -1 and y = -1
So, we have
(-1, -1)

The vertex of the given function y = 2x² + 4x+1 is (-1, -1) which is the correct answer would be an option (B).
The function is below given by,
y = 2x² + 4x + 1
Differentiate with respect to x to get the derivative of the above function,
y' = dy/dx = d/dx (2x² + 4x + 1)
y' = 4x + 4
Equating the derivative of the function to zero
y' = 0
4x + 4 = 0
4x = -4
Divide by 4 into both sides of the equation,
x = -1
Substitute x = -1 in the given function y = 2x² + 4x + 1
y = 2(-1)² + 4(-1) + 1
y = 2(1) - 4 + 1
y = -1
Therefore, the vertex of the given function is (-1, -1).

A. solve the formula for h
B. what is the height of a container if the volume is 56.52 cubic inches and the radius is 1.5 inches? Round to the nearest tenth
A. The formula for h is h = V / πr².
B. The height of a container if the volume is 56.52 cubic inches and the radius is 1.5 inches is 8 inches.
How to calculate the value?The volume of a cylinder is calculated thus:

where π = 3.142
r = radius
h = height
Therefore, the height will be:
V = πr²h
We have to make h the subject of the formula. This will be:
h = V / πr²
The height of a container if the volume is 56.52 cubic inches and the radius is 1.5 inches will be:
h = V / πr²
h = 56.52 / (3.142 × 1.5²)
h = 56.52 / 7.0695

What is the value of p will the function be continuous?
The value of p that will guarantee the continuity of the function is given as follows:
p = 6.5.
What is the continuity concept?A function defined by f(x) is continuous at a point x = a if it is defined at x = a, and the lateral limits are equal, that is:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
In the context of this problem, the continuity of the function will be guaranteed if the lateral limits at x = -1 are equal.
To the left of x = -1, the function is less than -1, hence the lateral limit is:
lim x -> -1^- f(x) = lim x -> -1 (-2x² - 8x + 3) = -2(-1)² - 8(-1) + 3 = 9.
To the right of -1, the function is greater than -1, hence the lateram limit is:
lim x -> -1^+ f(x) = lim x -> -1 (4x + 2p) = 4(-1) + 2p = -4 + 2p.
The lateral limits have to be equal for the function to be continuous, hence:
-4 + 2p = 9
2p = 13
p = 13/2
p = 6.5.

What is the input value (x) in the given function?A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.
Given the data in the question;
k( x ) = 6x - 12k( x ) = 15x = ?To determine the value of x, equate the function to 15 and solve for x.
