Answer:
Surface area add together all 6 sides = 24+36+108=168m^2
Volume L x W x D = 2 x 6 x 9 = 108 m ^3
Step-by-step explanation:
2 x 6 = 12
12 x 2 = 24 base and top
2 x 9 = 18
2 x 18 = 36 identical pair sides
6 x 9 = 54
2 x 54 = 108 identical pair sides
Surface area add together all 6 sides = 24+36+108=168m^2
Volume L x W x D = 2 x 6 x 9 = 108 m ^3

so here we need two number that give 7 when multiplied and 6 when subtracted
7 and 1 are the numbers because
7*1=7 and ,
7-1=6 so,
x^2 + (7-1)x -7
x^2 +7x -x -7
take common from first two terms and from third and fourth term
x(x+7)-1(x+7)
take (x+7) as common
(x+7)(x*1 -1*1)
(x+7)(x-1)

The volume of the prism is 864 cubic units.
To calculate the volume of a prism, we use the formula: Volume = Area of Base x Height. In this case, the area of the base is given as 48 square units, and the height is given as 18 units.
To find the volume, we multiply the area of the base by the height:
Volume = 48 x 18 = 864 cubic units.
Therefore, the volume of the prism is 864 cubic units. Since the base area is given in square units and the height is given in units, the volume is expressed in cubic units. In this case, the units are mm³ (cubic millimeters).
Thus, the proper calculation yields a volume of 864 mm³.

What is the slope of the line that contains the points (-2, 5) and (6, -3)?
Answer:
-1
Step-by-step explanation:
(-2 , 5) = (x1 , y1)
(6 , -3) = (x2 , y2)
slope of a line = y2 - y1/x2 - x1
=-3 - 5/6 - (-2)
=-8/6+2
=-8/8
=-1
therefore slope of a line is -1.
Two roots of a third degree polynomial function f(x) are -4 and 4. Which statement describes the number and nature of all
roots for this function?
* f(x) has three imaginary roots.
* f(x) has three real roots.
* f(x) has two real roots and two imaginary roots.
* f(x) has three real roots and one imaginary root.
Answer:
f(x) has three real roots.
Step-by-step explanation:
f(x) has three real roots.
A third degree polynomial function with real coefficients has exactly 3 roots.
Furthermore, all complex roots come in pairs, either there is none, or there are exactly two conjugates, which are in the form e1+i(e2) and e1-i(e2) where e1 and e2 are polynomial expressions.
This also means that a third degree polynomial with real coefficients has at least one real root, or three.
Since we are given two real roots for the given polynomial, the third root cannot be complex alone, so the only possibility is that there are three real roots.
If b is real, then all three roots are real.
If b is not real, then two of the roots are real (-4 and 4) and one is imaginary.
What is a polynomial?Polynomial is an equation written with terms of the form kx^n.
where k and n are positive integers.
There are quadratic polynomials and cubic polynomials.
Example:
2x³ + 4x² + 4x + 9 is a cubic polynomial.
4x² + 7x + 8 is a quadratic polynomial.
We have,
The polynomial function f(x) has degree 3 and two roots -4 and 4, we know that (x + 4) and (x - 4) are factors of the function.
To see why, note that when x = -4, the factor (x + 4) becomes zero, making the function zero.
Similarly, when x = 4, the factor (x - 4) becomes zero, making the function zero.
Now,
Since the function has degree 3 and two factors of degree 1, we can conclude that the third factor is also of degree 1.
This means that the function can be written in the form:
f(x) = a (x + 4) (x - 4) (x - b)
where a and b are constants.
We don't know the value of b, but we know that it is a real number (since the other two roots are real).
Thus, the three roots of the function are -4, 4, and b.
Now,
To determine whether the roots are all real or some are imaginary, we need to know the value of b.
If b is real, then all three roots are real.
If b is not real, then two of the roots are real (-4 and 4) and one is imaginary (b).
Thus,
If b is real, then all three roots are real.
If b is not real, then two of the roots are real (-4 and 4) and one is imaginary.

O A. The volume of box Y is of the volume of box X
OB. The volume of box Y is
of the volume of box X
O c The volume of box Y is to of the volume of box X.
OD. The volume of box Y is of the volume of box X.
E. The volume of box Y is 256 of the volume of box X.
Answer:
The volume of box Y is 1/64 of the volume of box X
Step-by-step explanation:
Since. The edge of a box Y is 1/4 the lengtj of box X ;
The volume is 3 dimensional and each dimension of Y is 1/4th the dimension of X
The volume of Y will be (1/4)^3 the volume of Y
(1/4)^3 = 1/4 * 1/4 * 1/4 = 1/64
For instance, if edge of X = 8
Edge of Y which is 1/X ; edge Y = 1/4(8) = 2
Volume, X 8^3 = 512
Volume Y = 2^3 = 8
8/512 = 1 / 64

Answer:
There are 25 students in the class.
Step-by-step explanation:
In order to find the number of students in the class, you can add the number of data points together. Because the name of each person will only be recorded once and only to one data value, that means by adding the total number of data points collected, you can find out the number of students in the sixth-grade class. There are three data points on 3, two data points on 4, five data points on 5, eight data points on 6, two data points on 7, one data point on 8, and four data points on 9, this means the total number of students will be 3 + 2 + 5 + 8 + 2 + 1 + 4 = 25 students, so this will be your answer.
Elena is going to a farmer's market for fresh produce. She has two markets to

0.6
0.5
Asparagus
0.85
0.84
Assuming that the availability of cherries and the availability of asparagus are
independent of each other, which market should Elena choose to maximize
her chance of buying both?
A. South market. There is a 0.42 probability of both cherries and
asparagus being available.
B. North market. There is a 0.3 probability of both cherries and
asparagus being available.
c. South market. There is a 0.3 probability of both cherries and
asparagus being available.
D. North market. There is a 0.51 probability of both cherries and
asparagus being available.
Answer:
D (north, .51)
Step-by-step explanation:
since the numbers are higher for north, it is the right answer.
.6*.85=.51
D. North market. There is a 0.51 probability of both cherries and asparagus being available.
What is independent events ?If the incidence of one event does not affect the probability of the other event then the events are independent of each other and called independent events.
Now, if A and B be two events which are independent,
then P(A∩B) = P(A)×P(B)
How to find which market Elena choose to maximize her chance of buying both?In the table in given problem, the probability of cherries and asparagus are higher for north market.
For the north market,
The probability of produce cherries = P(A) = 0.6
The probability of produce asparagus = P(B) = 0.85
where A and B are the events of produce cherries and asparagus respectively.
Here, A and B are independent events.
Then probability for maximize her choice is P(A∩B) = P(A)×P(B)
= 0.6×0.85
= 0.51
∴ Elena choose north market to maximize her chance of buying both and the probability is 0.51

A hunter is practicing his aim using a practice target. He takes 5 shots. All 5 shots hit the target, but they do not hit or surround the bullseye. In addition, all 5 shots are very spread apart on the target. Classify the hunter's accuracy and precision.
a. High accuracy and high precision
b. High accuracy and low precision
c. Low accuracy and high precision
d. Low accuracy and low precision
Answer:
D
Step-by-step explanation:
Accuracy refers to how close measurements are to the "true" value (which is the target in this case), while precision refers to how close measurements are to each other.
Since the arrows fall away from the bullseye and are spread out I would classify this as low accuracy and low precision.

What is the similarity
statement for the triangle
pair?
Answer:
side-side-side
Step-by-step explanation:
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
The similarity statement for the pair of triangles is triangle XYZ similar triangle ENW by AA similarity criterionand mathematically represented as: [tex]\Delta XYZ \, \sim \, \Delta ENW\\[/tex]
Given: In the figure, the angle YXZ is equal to angle NEW and the angle XZY is equal to angle ENW are marked in the corresponding triangles.
To prove triangle XYZ similar triangle ENW by following steps:
Step 1: Consider the triangle XYZ and triangle ENW.
Compare the angle in both the triangles.
[tex]\Delta XYZ \, and\, \Delta ENW\\[/tex][tex]\angle YXZ = \angle NEW\\[/tex][tex]\angle XZY = \angle NWE[/tex]Step 2: Applying the AA similarity criterion:
The Angle-Angle AA similarity criterion states if two angles of one triangle is equal to the corresponding triangle, then two triangles are similar,
This implies triangle XYZ and triangle ENW by AA similarity criterion.
Therefore, the triangle XYZ and triangle ENW by AA similarity criterion. That is [tex]\Delta XYZ \, \sim \, \Delta ENW\\[/tex]
