The volume of the rectangular prism is V = 936 cm³
What is the Volume of a Rectangle?The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
To find the volume of the figure, we need to calculate the volumes of the two rectangular prisms separately and then add them together.
The volume of a rectangular prism is given by the formula:
Volume = length x width x height
For the first prism:
Length = 12 centimeters
Width = 9 centimeters
Height = 2 centimeters
Volume of first prism = 12 cm x 9 cm x 2 cm = 216 centimeters³
For the second prism:
Length = 10 centimeters
Width = 9 centimeters
Height = 8 centimeters
Volume of second prism = 10 cm x 9 cm x 8 cm = 720 centimeters³
Now, we add the volumes of the two prisms together to get the total volume of the figure:
216 cubic centimeters + 720 cubic centimeters = 936 centimeters³
Hence , the rectangular prism has volume of 936 cm³

A bacteria with an initial size of 180in2 grows by 27% every minute. What will the size of the bacteria be after 8hours
Answer:
The size of the bacteria after 8 hours will be of [tex]1.2 \times 10^{52}[/tex] squared inches.
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
[tex]F(t) = F(0)(1+r)^{t}[/tex]
In which F(0) is the initial value and F is the growth rate.
A bacteria with an initial size of 180in2 grows by 27% every minute.
This means that [tex]F(0) = 180, r = 0.27[/tex]. So
[tex]F(t) = F(0)(1+r)^{t}[/tex]
[tex]F(t) = 180(1+0.27)^{t}[/tex]
[tex]F(t) = 180(1.27)^{t}[/tex]
In which t is measured in minutes,
What will the size of the bacteria be after 8hours
8 hours has 8*60 = 480 minutes, so this is F(480).
[tex]F(480) = 180(1.27)^{480} = 1.2 \times 10^{52}[/tex]
The size of the bacteria after 8 hours will be of [tex]1.2 \times 10^{52}[/tex] squared inches.
Find the complex factors of the quadratic trinomial x^2 + 8x +17
Answer: Factoring x2+8x+17
The first term is, x2 its coefficient is 1 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is +17
Step-1 : Multiply the coefficient of the first term by the constant 1 • 17 = 17
Step-2 : Find two factors of 17 whose sum equals the coefficient of the middle term, which is 8 .
-17 + -1 = -18
-1 + -17 = -18
1 + 17 = 18
17 + 1 = 18
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Parabola, Finding the Vertex:
2.1 Find the Vertex of y = x2+8x+17
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is -4.0000
Plugging into the parabola formula -4.0000 for x we can calculate the y -coordinate :
y = 1.0 * -4.00 * -4.00 + 8.0 * -4.00 + 17.0
or y = 1.000
Parabola, Graphing Vertex and X-Intercepts :
Root plot for : y = x2+8x+17
Axis of Symmetry (dashed) {x}={-4.00}
Vertex at {x,y} = {-4.00, 1.00}
Function has no real rootsvSolving x2+8x+17 = 0 by Completing The Square .
Subtract 17 from both side of the equation :
x2+8x = -17
Now the clever bit: Take the coefficient of x , which is 8 , divide by two, giving 4 , and finally square it giving 16
Add 16 to both sides of the equation :
On the right hand side we have :
-17 + 16 or, (-17/1)+(16/1)
The common denominator of the two fractions is 1 Adding (-17/1)+(16/1) gives -1/1
So adding to both sides we finally get :
x2+8x+16 = -1
Adding 16 has completed the left hand side into a perfect square :
x2+8x+16 =
(x+4) • (x+4) =
(x+4)2
Things which are equal to the same thing are also equal to one another. Since
x2+8x+16 = -1 and
x2+8x+16 = (x+4)2
then, according to the law of transitivity,
(x+4)2 = -1
We'll refer to this Equation as Eq. #2.2.1
The Square Root Principle says that When two things are equal, their square roots are equal.
Note that the square root of
(x+4)2 is
(x+4)2/2 =
(x+4)1 =
x+4
Now, applying the Square Root Principle to Eq. #2.2.1 we get:
x+4 = √ -1
Subtract 4 from both sides to obtain:
x = -4 + √ -1
In Math, i is called the imaginary unit. It satisfies i2 =-1. Both i and -i are the square roots of -1
Since a square root has two values, one positive and the other negative
x2 + 8x + 17 = 0
has two solutions:
x = -4 + √ 1 • i
or
x = -4 - √ 1 • i

A hotel manager is adding a tile border around the hotel's rectangular pool. let n represent the width of the pool, in feet. the length is 3 more than 3 times the width, as shown. Write two expressions that represent the perimeter of the pool.
Answer:
[tex]2(4n+3)[/tex]
[tex]8n+6[/tex]
Step-by-step explanation:
We are given that
Let n represent the width of pool
Length of pool=[tex]3n+3[/tex]
We have to find two expression which represent the perimeter of the pool.
We know that
Perimeter of rectangle=[tex]2(l+b)[/tex]
Where l=Length of rectangle
b=Width of rectangle
Using the formula
Perimeter of pool=[tex]2(n+3n+3)[/tex]
Perimeter of pool=[tex]2(4n+3)[/tex]
Perimeter of pool=[tex]8n+6[/tex]
Hence, two expressions that represent the perimeter of the pool is given by

The next model of a sports car will cost 6.9% less than the current model. The current model costs $48,000. How much will the price decrease in dollars? What
will be the price of the next model?
Decrease in price:
Price of next model:
Answer:
Price is decreased by $3,312
And, the price of the next model is $44,688
Step-by-step explanation:
The computation is shown below:
Given that the current model cost is $48,000
And, there is 6.9% lower than the current model
So, the price would decrease in dollars is
= $48,000 × 6.9%
= $3,312
The price of the next model is
= $48,000 - $3,312
= $44,688
find the positive zero of the function f(x)=x^(2)-5x-7 and round two decimal places
Answer:
6.14
Step-by-step explanation:
Given the function f(x)=x^(2)-5x-7, when f(x) = 0
x^(2)-5x-7 = 0
Using the general formula
x = 5±√5²-4(-7)/21(1)
x= 5±√25+28/2
x = 5±√53/2
x = -5±7.28/2
x = 5+7.28/2 and 5-7.28/2
x = 12.28/2 and -2.28/2
x = 6.14 and -1.14
Hence the positive zero is 6.14

Answer:
A : 3080
Step-by-step explanation:
In order to find volume, you have to multiply all the 3 sides. (Multiply height, length and width)
22 x 10 = 220.
220 x 14 = 3080.
Therefore the volume of the water is 3080 in.

Write the equation of the perpendicular bisector of the segment AB.
A (1, 5) and B (7, -1)
Answer:
The equation of the perpendicular bisector of the segment AB is [tex]y = x - 2[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
Perpendicular lines and slopes:
If two lines are perpendicular, the multiplication of their slopes is -1.
Equation of the perpendicular bisector of the segment AB.
Equation of a line that passes through the midpoint of segment AB and is perpendicular to AB.
Midpoint of segment AB:
Mean of their coordinates x and y. So
(1+7)/2 = 4
(5-1)/2 = 2
So (4,2).
Slope of segment AB:
When we have two points, the slope between them is given by the change in y divided by the change in x.
In segment AB, we have points (1,5) and (7,-1). So
Change in y: -1 - 5 = -6
Change in x: 7 - 1 = 6
Slope: -6/6 = -1
Equation of the perpendicular bisector:
The slope, multiplied with the slope of segment AB, is -1. So
[tex]-1m = -1[/tex]
[tex]m = 1[/tex]
So
[tex]y = x + b[/tex]
Passes through (4,2), which means that when [tex]x = 4, y = 2[/tex]. So
[tex]y = x + b[/tex]
[tex]2 = 4 + b[/tex]
[tex]b = -2[/tex]
So
[tex]y = x - 2[/tex]

My calculator works with mixed numbers very nicely, as many graphing calculators do.
Step-by-step explanation:
convert the fractions to whole numbers. the first one is:
4 × 7, then add 3, or 31/4.
the second one is 6 × 1, then add 5, or 11/6.
then you have 31/4 + 11/6. then you make a common denominator, which would be 12 (6 and 4 both go into 12).
3 × 31 = 93, so then the first fractions becomes:
93/12
second fraction becomes 11 × 2 = 22, then:
22/12.
so now you have 93/12 + 22/12 = 115/12, or 9 7/12
