The bottom cup in a 73 cm tall stack of nested identical cups is 10 cm tall. If each additional cup adds 1.5 cm to the height of the stack, how many total cups are in the stack?
Answer:
43 cups
Step-by-step explanation:
Subtract the height of the one cup from the stack
73 - 10
63
The rest of the cup each add 1.5 cm to the stack
take the remaining height and divide by 1.5 for each cup
63 cm/ 1.5 cm per cup
42 cup
There are 42 cups in the remaining part of the stack
Plus the 1 cup that is 10 cm
42+1 = 43 cups total in the stack
Answer:
[tex]\boxed{\sf 43 \ cups}[/tex]
Step-by-step explanation:
The stack is 73 cm tall, one cup is 10 cm.
Let’s subtract the height of the one cup from the height of the stack.
[tex]\sf 73 - 10\\=63[/tex]
The cups left each add 1.5 cm.
Let x be the cups left.
[tex]\sf 1.5x=63\\x=\frac{63}{1.5} \\x=42[/tex]
Add the 1 to the cups left, because that first cup was subtracted from the height of the stack.
[tex]\sf 42+1\\=43[/tex]
Give an example of how you would solve an equation by completing the square. Describe the steps.
Answer:
Step-by-step explanation:
to solve an equation by completing the square in a quadratic formula
f(x)=ax²+bx+c
example :x²-6x-16=0
first rearrange if necessary, move the constant to one side .
x²-6x=16
second you find a new term to complete the square which is (b/2)², and add the term to both sides.(6/2)²=3²=9
x²-6x+9=16+9
x²-6x+9=25
third factorize : find the common factor between 6 and 9 which is 3
x²-6x+9=25
(x-3)²=25
last solve for x: (x-3)²=25
x-3=√25
x=3±5
x=3+5=8 or 3-5=-2

1. How many terms are in the polynomial?
2. What is the degree of the polynomial?
3. How would you classify the polynomial?
Answer:
Step-by-step explanation:
A term, loosely defined, is a product of numbers and variables. Terms are separated from one another with a + or a - sign. So we have 2 terms here.
The degree of the polynomial, because it is just in terms of x and no other variable, is the highest degree'd term. Our highest degree of x is 3, so this is a third degree polynomial.
It is classified by its number of terms:
1 term is a monomial, 2 terms is a binomial, 3 is a trinomial, and anything higher is just called a "polynomial". This has 2 terms so it is a binomial.
The answer is:
⇨ a third-degree binomial.Work/explanation:
Here's how we classify polynomials based on the number of terms:
monomial - has only one term
binomial - has two terms
trinomial - has three terms
polynomial - has four terms or more
As for degrees, those are the highest exponents the polynomial.
Now, [tex]\sf{14x^3+x^2}[/tex] has 2 terms so it's a binomial; the highest exponent is 3.
Hence, this is a third-degree binomial.P(x) has factors (x-2), (x+1), and (x-3). Decide if there is only one polynomial that has these factors. Justify your answer.
Answer:
See explanation
Step-by-step explanation:
if multiply the 3 factors together you get
(x² - x - 2)(x - 3) - trinomial x binomial
x³ - 3x²- x² + 3x - 2x + 6 - polynomial
x³ - 4x² + x + 6, this is the polynomial with those factors.
Poly means many so it could be a bigger polynomial with more factors but if it is limited to only these factors than there is just the one polynomial.
The polynomial is x³ - 4x² + x + 6 with factors (x-2), (x+1), and (x-3)
What is polynomial?A polynomial is the defined as mathematical expression that have a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
Given that ,
P(x) has three factors (x-2), (x+1), and (x-3).
Multiplying the 3 factors together, we get
⇒ (x-2)(x+1)(x-3)
⇒ [x(x-3) - 2(x+1)](x-3)
⇒ (x² - x - 2)(x - 3)
⇒ x³ - 3x²- x² + 3x - 2x + 6
Rearrange the terms likewise and apply arithmetic operations
⇒ x³ - 4x² + x + 6
Hence, the polynomial is x³ - 4x² + x + 6 with factors (x-2), (x+1), and (x-3).

Nadia built a robot to filter air and water efficiently. She expects the robot to filter more than 343 liters of
air and water while using less than 49 Joules of energy.
12A + 8W > 343 represents the number of minutes the robot filters air A and water IV to hiter more
than 343 liters of air and water.
3A +41V < 49 represents the number of minutes the robot hiters air and water while using less than 49
Joules of energy
Does the robot meet both of Nadia's expectations by filtering air for 20 minutes and filtering water for 15
minutes?
Choose 1 answer.
A. The robot meets both of Nadia's expectations.
B. The robot filters the expected amount of air and water, but it doesn't use the expected amount
of energy
C. The robot uses the expected amount of energy, but it doesn't filter the expected amount of air
and water.
D. The robot doesn't meet either of Nadia's expectations.
Answer:
The correct option is;
B. The robot filters the expected amount of air and water, but it doesn't use the expected amount of energy
Step-by-step explanation:
The given requirements are;
Volume of air and water to be filtered by the robot = 343 liters
The amount of energy consumed by the robot < 49 joules
The number of minutes the robot filters air and water to filter more than 343 liters = 12A + 8W > 343
The number of minutes the robot filters air and with less than 49 Joule of energy = 3A + 4W < 49
Given that filtering air takes 20 minutes, filtering water takes 15 minutes, we have;
To filter more than 343 liters, we have
12*20 + 8*15 = 360 > 343
The robot meets the amount of air and water requirement
To filter with less than 49 joules we have
3*20 + 4*15 = 120 > 49
Therefore, the robot does not meet the energy requirement
The correct option is the robot filters the expected amount of air and water, but it doesn't use the expected amount of energy.

Aiko is finding the sum (4 + 5i) + (–3 + 7i). She rewrites the sum as (–3 + 7)i + (4 + 5)i. Which statement explains the error Aiko made by using a mathematical property incorrectly?
Answer:
The error was made when they factored out the i, so this would be the distributive property they did not do correctly.
Factoring out the i was never needed.
Answer:
She shouldn't have factored out the i.
Step-by-step explanation:
In both parentheses, only one of the two additives had an "i" in it, so only one of them could have i factored out of it. If she wanted to factor out the i, the equation would look like this:
(4/i + 5)i + (-3/i + 7)i.
If anything, she should have done:
5i+7i + 4-3=
12i + 1.
Factoring out the i was unnecessary.

Answer:
the answer is XY = 24 units.
Step-by-step explanation:
Given:
XY is tangent to the circles with center P and O respectively.
OX=16 units
PY=6 units
OP=26 units
To find:
Side XY = ?
Solution:
As per given statement, the diagram of two circles and their tangent is shown in the diagram.
We need to do one construction here,
Draw a line parallel to tangent XY from P towards OX such that it meets OX at A .
Now, let us consider triangle [tex]\triangle OAP[/tex]. It is a right angled triangle.
With sides Hypotenuse, OP = 26 units
Perpendicular, OA = 16 -6 = 10 units
Base AP is equal to XY.
If we find the value of Base AP, the value of XY is calculated automatically.
Let us use pythagorean theorem in [tex]\triangle OAP[/tex]:
According to pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OP^{2} = AP^{2} + OA^{2} \\\Rightarrow 26^2=XY^2+10^2\\\Rightarrow XY^2 = 676- 100\\\Rightarrow XY = \sqrt{576}\\\Rightarrow XY = 24\ units[/tex]
Hence, the answer is XY = 24 units.
