Answer:
360cm3
Step-by-step explanation:
To do this, you can multiply the base (l * w) by the height to determine the volume. This would be 36*10=360. Then remember that it is a 3 dimensional shape, so the valume is cubed.

When x 12" to the "-x^3+3x^2+5x+1"
The value of expression -x³+3x²+5x+1 is -1235 when x is 12
What is Expression?An expression is combination of variables, numbers and operators.
Given polynomial is -x³+3x²+5x+1
We need to find the value of the polynomial when x is 12.
To find this we just need replace x with 12
-(12)³+3(12)²+5(12)+1
Minus twelve cube plus three times of twelve square plus five times of twelve plus one
-1728+3(144)+5(12)+1
-1728+432+60+1
-1728+493
-1235
Hence, the value of expression -x³+3x²+5x+1 is -1235 when x is 12

Complete Question:
Flag
Let ŷ represent the profit (in thousands of dollars) for a certain company xx years after 1960. A statistician calculates a linear model
ŷ = -1.23 x + 16.07
Use the model to estimate the profit in 1965. Your answer should be in dollars, not thousands of dollars.
Answer:
[tex]\=y =\$9.92[/tex]
Step-by-step explanation:
From the question we are told that:
Number of years [tex]N=1960-1965=>5years[/tex]
Linear model [tex]\=y = -1.23 x + 16.07[/tex]
Therefore Inputting values into the model we have
[tex]\=y = -1.23 (5) + 16.07[/tex]
[tex]\=y = -6.15+ 16.07[/tex]
[tex]\=y =\$9.92[/tex]
The perimeter of a rectangle is 84 cm. the length is 3 cm shorter than the width. find the length and width of the rectangle.
Taking into account the definition of a system of linear equations, the length and width of the rectangle is 22.5 cm and 19.5 cm respectively.
System of linear equationsSystems of linear equations are groupings of first degree equations with the same unknowns, of which a common solution must be found.
In the systems of equations, the values of the unknowns must be found, with which, when replaced, they must give the solution proposed in both equations.
Number of sodas and hot dogs soldIn this case, a system of linear equations must be proposed taking into account that:
"x" is the length of the rectangle."y" is the width of the rectangle.You know:
The perimeter of a rectangle is 84 cm. The perimeter of a flat geometric figure is called the length of its contour. It is obtained as a result of the sum of the sides of a flat geometric figureThe length is 3 cm shorter than the width.The system of equations to be solved is
2x + 2y= 84
x= y + 3
The substitution method is a way to solve systems of equations. To use the substitution method, you choose an equation and find an expression for one of the variables in terms of the other variable. Then substitute that expression for the variable in the other equation.
In this case, substituting the second equation in the first one you get:
2×(y+3) + 2y= 84
Solving:
2y+ 2×3 + 2y= 84
2y+ 6 + 2y= 84
2y + 2y= 84 - 6
4y= 78
y= 78÷4
y= 19.5
Replacing this value in the second equation, you get:
x= 19.5 + 3
x= 22.5
Finally, the length of the rectangle is 22.5 cm and the width of the rectangle is 19.5 cm.

what is variable ?In mathematics, a variable is an alphabet or phrase that denotes an unknowable quantity, unknowable value, or unknowable number. In the case of algebraic expressions or algebra, the variables are employed specifically. The two primary categories of variables are categorical and numeric. Then, for categorical and numerical variables, respectively, nominal or ordinal and discrete or continuous subcategories are created for each category. This section provides a quick overview of these types.

The term asymptote in math is defined as a line that the graph of a function approaches as either x or y go to positive or negative infinity.
Here we have to find the horizontal asymptote of a limit.
The process of finding the horizontal asymptote is the line y = 0 is called the asymptote of the graph, and it also represents the value that f(x) will never quite reach.

The perimeter of a square room is 80 feet. How many floor tiles 1 foot square would be needed to cover the area of the room
We would require 400 square tiles, each measuring one square foot, to cover the whole surface of the square room.
If the perimeter of the room is 80 feet, we know that all four sides of the square room have the same length. To find the length of each side, we can divide the perimeter by 4: 80 feet / 4 = 20 feet.
Now that we know the length of each side of the room, we can find the area of the room by squaring that measurement: 20 feet x 20 feet = 400 square feet.
To find the number of floor tiles needed to cover the area of the room, we divide the total area of the room by the area of each tile: 400 square feet / 1 square foot/tile = 400 tiles.
So, to cover the entire area of the square room, we would need 400 square tiles of one square foot each.

Energy produced by 1 gallon = joules
by $1 , you can get 1/3 gallon

The simplified form of radical √18 . 3√5 = 9√10
What is radical?In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol.
For example, ³√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.
The term underneath the radical symbol is called the radicand.
Given radical
√18 . 3√5
⇒ √(9 × 2) . 3√5
⇒ 3√2 . 3√5
⇒ 9(√2.5)
⇒ 9√10
⇒ 28.46
Hence, The radical √18 . 3√5 can be simplified to 9√10 having value = 28.46
