The height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).
The formula for the volume of a rectangular prism is V = Ah, where A is the area of the base and h is the height. Since we are given the volume and the area of the base, we can solve for the height. We have V = ([tex]x^{2}[/tex]-2) * h and V = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3), so we can set these two equations equal to each other and solve for h.
([tex]x^{2}[/tex]-2) * h = ([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3)
Expanding both sides, we get:
[tex]x^{2}[/tex]h - 2h = [tex]x^{3}[/tex]h - 3[tex]x^{2}[/tex]h + 5xh - 3h
Combining like terms, we get:
([tex]x^{3}[/tex] - 3[tex]x^{2}[/tex] + 5x - 3 - [tex]x^{2}[/tex] + 2 - 5x + 3) * h = 0
Simplifying, we get:
([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) * h = 0
Since [tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2 cannot equal 0 (since it's a cubic polynomial), we can divide both sides by ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2) to solve for h:
h = 0 / ([tex]x^{3}[/tex] - 4[tex]x^{2}[/tex] + 2)
So the height of the prism is x-3+ (7x-9)/([tex]x^{3}[/tex]-3[tex]x^{2}[/tex]+5x-3).

First, rewrite 13/30 and 9/20 so that they have a common denominator
Answer:
Must determine the LCD. Think: what is the smallest (least) number divisible by both 30 and 20? You could, of course, just multiply 30 and 20, obtaining 600, but that would not be the LCD.
Note that 30 and 20 share the common factor 10. Multiplying 3 and 2 together produces 6. The LCD is 10*6 = 60. Note that both 30 and 20 divide into 60 with no remainder.
Then 19/30 = 2(19) / 2[30] = 38/60, and
13/20 = 3(13) / 3[20] = 39/60.
Which is larger, 38/60 or 39/60?
Write the relationship between these 2 numbers using the appropriate inequality operator.
Step-by-step explanation:
The fractions 13/30 and 9/20, when rewritten with a common denominator, are 26/60 and 27/60, respectively.
To rewrite the fractions 13/30 and 9/20 with a common denominator, we need to find the least common multiple (LCM) of the denominators, which is the smallest multiple that both 30 and 20 share.
The prime factorization of 30 is 2 * 3 * 5, and the prime factorization of 20 is 2 * 2 * 5. To find the LCM, we take the highest power of each prime factor that appears in either number:
LCM(30, 20) = 2 * 2 * 3 * 5 = 60
Now, let's rewrite the fractions with the common denominator of 60:
13/30 = (13/30) * (2/2) = (13 * 2) / (30 * 2) = 26/60
9/20 = (9/20) * (3/3) = (9 * 3) / (20 * 3) = 27/60
So, the fractions 13/30 and 9/20, when rewritten with a common denominator, are 26/60 and 27/60, respectively.

Pink rose plants are on sale for $3 each and white ones for $5 each. A gardener decides to buy 13 in total, choosing more white plants than pink. If the gardener spent $55, how many white plants did he buy?
Answer:
8
Step-by-step explanation:
If the gardener bought more white than pink, that could mean he could have bought 12 white and one pink, 11 white and 2 pink, 10 white and 3 pink, 9 white and 4 pink, 8 white and 5 pink, or 7 white and 6 pink.
If you plug in the numbers, for example with 7 and 6, that would equal $53, which is not correct. Continue to do this with all of the answers.
With 8 white roses and 5 pink roses, this would equal $55 (40+15), which is the answer.
By solving form expressions the gardener bought 5 pink plants.
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, constants, and operators, which when evaluated, produce a value. Expressions can include mathematical symbols such as addition, subtraction, multiplication, division, exponents, roots, logarithms, and trigonometric functions.
Let's use algebra to solve this problem.
Let's assume that the gardener bought x pink plants and y white plants. We know that:
The gardener bought 13 plants in total: x + y = 13
The gardener spent $55: 3x + 5y = 55
The gardener chose more white plants than pink: y > x
We can use the first equation to solve for x in terms of y:
x = 13 - y
Now we can substitute this into the second equation:
3(13 - y) + 5y = 55
Simplifying and solving for y:
39 - 3y + 5y = 55
2y = 16
y = 8
So the gardener bought 8 white plants. To find out how many pink plants were bought, we can substitute this value into the first equation:
x + y = 13
x + 8 = 13
x = 5
So the gardener bought 5 pink plants.

What is the slope of the line that passes through the points (–9, 2) and (0, 4)?
Answer:
2/9
Step-by-step explanation:
Slope = y2- y1/x2 - x1
Given
x1 = -9
y1 = 2
x2 = 0
y2 = 4
Therefore
Slope = 4 - 2 /0 -(-9)
= 4 - 2/0 + 9
= 2/9
Answer:
2/9 is correct, or just .22
Step-by-step explanation:
Use the formula [tex]\frac{x^2 - x^1}{y^2 - y^1} = \frac{rise}{run} = \frac{-9 - 0}{2 -4}[/tex]

The common ratio of a geometric series is \dfrac14
4
1
start fraction, 1, divided by, 4, end fraction and the sum of the first 4 terms is 170
Answer:
The first term is 128
Step-by-step explanation:
The common ratio of the geometric series is given as:
[tex]r = \frac{1}{4} [/tex]
The sum of the first 4 term is 170.
The sum of first n terms of a geometric sequence is given b;
[tex]s_n=\frac{a_1(1-r^n)}{1-r}[/tex]
We put the common ratio, n=4 and equate to 170.
[tex]\frac{a_1(1-( \frac{1}{4} )^4)}{1- \frac{1}{4} } = 170[/tex]
Simplify:
[tex]\frac{a_1(1- \frac{1}{256} )}{ \frac{3}{4} } = 170[/tex]
[tex] \frac{255}{256} a_1 = \frac{3}{4} \times 170[/tex]
[tex]\frac{255}{256} a_1 = \frac{255}{2} [/tex]
[tex]\frac{1}{256} a_1 = \frac{1}{2} [/tex]
[tex] a_1 = \frac{1}{2} \times 256[/tex]
[tex]a_1 = \frac{1}{2} \times 256 = 128[/tex]

If point A = (4,4) and B = (8,7)
The slope of M would be 3/4.
Step-by-step explanation:
m = y^2 - y^1/x^2 - x^1 = 7 - 4/ 8 - 4 = 3/4. m = 3/4.
y = mx + b
y = 3/4 x + b
4 = (3/4)(4) + b
b = 4 - 3 = 1
The equation of line AB is y = 3/4 x + 1.

The graph shows the speed of a ball in free fall for 10 seconds. Which is the constant of proportionality shown in the graph?
Given:
The graph shows the speed of a ball in free fall for 10 seconds.
We need to determine the constant of proportionality for the given graph.
Constant of proportionality:
The constant of proportionality can be determined using the formula,
[tex]\frac{y}{x}=k[/tex]
Where k is the constant of proportionality.
Let us consider any of the coordinate from the graph and substitute in the formula.
Consider the coordinate (4,40) and substitute in the above formula.
Thus, we have;
[tex]\frac{40}{4}=k[/tex]
[tex]10=k[/tex]
Thus, the constant of proportionality is 10 meters per second squared.
Answer:

Angle 1 is 100 degrees. What is the measure of angle 3?
Answer:
Angle 3 is also 100
Step-by-step explanation:
They are vertical angles and vertical angles are always congruent.
The angle 3 is in the given figure is ∠3 = 100°.
What are parallel lines?
The parallel lines are a group of straight lines that never intersect with one another. The distance between two parallel is always the same.
The measure of angle 1 is given as ∠1 = 100°.
When two lines intersect each other, the pair of vertically opposite angles are equal.
Since, angle 1 and angle 3 are vertically opposite, they are equal.
Thus, ∠3 = 100°.
