Answer:
12
Step-by-step explanation:
f(x) = x^2 - x^3
Let x=-2
f(-2) = (-2)^2 - (-2)^3
= 4 - (-8)
= 4+8
= 12
Answer:
f(-2)=12
Step-by-step explanation:
We are given:
f(x)=x^2 - x^3
We are told to find f(-2). We need to find f(x) when x is equal to -2. Therefore, we can substitute -2 in for each x.
f(-2)= (-2)^2 - (-2)^3
Evaluate the exponent -2^2 .
-2^2= -2 * -2= 4
f(-2)= 4- (-2)^3
Evaluate the exponent -2^3
-2^3= -2* -2*-2= -8
f(-2)= 4- -8
f(-2)= 4+8
f(-2) =12
f(-2) is equal to 12, therefore D is correct.

How many gallons of water will be in the fish tank after 3 minutes? 0.5 mins = 0.8 gallons
Answer:
0.8 gallons for 0.5 minutes.
Multiply by 2 to get gallons per minute :
0.8 x 2 = 1.6 gallons per minute
Multiply gallons per minute by 3 minutes:
1.6 x 3 = 4.8 gallons in 3 minutes.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Brayden conducted a scientific experiment. For a certain time, the temperature of a compound rose 2 2/5 degrees in 1/5 of an hour. How much did the temperature of the compound rise in one hour?
Answer: 12 degrees or 11 5/5 or 60/5
Step-by-step explanation:
Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.
For the number line you just have to find 1/5 and 2 2/5 on it and mark it.

Answer:
B
Step-by-step explanation:
The initial value for a function is the value of y when x=0. For function A, we can see from the table that when x = 0, we have y = 4. For function B, we plug in 0 in our equation and solve: y = 3(0) + 5, or y = 5. So, because function B has a larger value of y when x = 0, function B has the greater initial value because the initial value for Function A is 4 and the initial value for function B is 5.
A three-dimensional figure with two parallel,congruent bases that are polygons.
Answer:
The answer would be a Prism.
Step-by-step explanation:
I am really sorry if this is wrong! But I think it is right...
The polygon is Prism.
What is Polygon?Polygons are defined as plane (two-dimensional) and closed shapes that are formed by joining three or more line segments with each other.
"Polygon" consists of Poly meaning "many" and gon meaning "angle". We see many different polygons around us.
Regular vs Irregular PolygonsIt is said that as per Euclidean Geometry, a polygon that is equiangular and equilateral is called a regular polygon while a polygon whose sides are not equiangular and equilateral is referred to as an irregular polygon. A regular polygon is always prefixed by the term "regular". Regular polygons are convex i.e., all the interior angles measure less than 180º.
In simple words, a regular polygon has all angles of the same measure at each vertex and all sides of the same length while a polygon that does not have sides of the same length and measurement of angles at each vertex different is referred to as an irregular polygon.
Given:
A three-dimensional figure with two parallel, congruent bases.
According to the polygon
A prism is a polyhedron that has two congruent and parallel faces (called the base and top), with all its remaining faces rectangles. This means that when a right prism is stood on its base, all the walls are vertical rectangles.

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

A survey at the local fair asked people of different ages about their favorite game to play. The results are displayed in the two-way relative frequency table below:

Flip-Frog l 7 9 4 12
Whack-a-Mole l 5 1 3
Ball Throw l 2 7 4 2
Ring Toss l 4 2 5 9
Suppose someone likes to play the Flip-Frog game. What is the conditional frequency they are between 18 and 22 years old? If needed, round answer to the nearest tenths.
A. 37.5%
B. 9.1%
C. 18.2%
D. 12.5%
Answer:
Step-by-step explanation:
To find the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old, we need to use the formula:
Conditional frequency = (Frequency of Flip-Frog players between 18 and 22) / (Total frequency of Flip-Frog players)
From the table, we see that the frequency of Flip-Frog players between 18 and 22 is 4, and the total frequency of Flip-Frog players is 9+4+12=25.
Therefore, the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old is:
Conditional frequency = 4 / 25 = 0.16 = 16%
Rounding to the nearest tenth, we get:
Conditional frequency = 16.0%

Apex Learning Study 4.2.1 What units do you use to report the area of a circle with a radius of 50 feet?
Answer:
in square feetStep-by-step explanation:
Area of anything is allways reported in square units. Usually that is square of given unit because it's the simplest way:
R = 50 ft
A = πR² = π•(50 ft)² = π • 50 ft • 50 ft = 2500π ft² ≈ 7854 ft²
{Of course you can re-calculate the units, ex.:
3 feet = 1 yard so 50 ft = 50/3 yd then
A = πR² = π•(50/3 yd)² = π • 50/3 yd • 50/3 yd = 2500/9 π yd² ≈ 872.7 yd² }

The amount for Sean owe in tax will be $3,150.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Sean earned $31,000 last year.
In the first $25,000 is taxed at 9% and income above is taxed at 15%.
Now,
Since, In the first $25,000 is taxed at 9%.
Hence, The amount of tax = 9% of $25,000
= 9/100 × $25,000
= $2,250
And, Income above is taxed at 15%.
Hence, The above income = $31,000 - $25,000
= $6,000
So, The tax for above income = 15% of $6,000
= 15/100 × 6,000
= $900
Thus, The total tax = $2,250 + $900
= $3,150
