Which polynomials are in standard form?
Answer:
Regular type is called the form in which polynomials are mostly used. The parameters are calibrated to the lowest degree. The polynomial x4 + 2x3+x+11 is standard, for instance, because four are most strong and three and one are the strongest.

To finish a project, you need to paint the lateral surfaces of a cube with side length 2.5 inches. Find the area that you need to paint.
Answer:
[tex]25 in^2[/tex]
Step-by-step explanation:
We want to find the lateral surface area of the cube.
The lateral surface area of a cube is given as:
[tex]A = 4a^2[/tex]
where a = length of side of the cube
Therefore, given that the length of the side of the cube is 2.5 inches, the area you need to paint is:
[tex]A = 4 * 2.5^2\\A = 25 in^2[/tex]

How do you write 3.0 × 10^2 in standard form?
Answer:
300
Step-by-step explanation:
First you would find 10^2, which is 100. Then you just multiply 100 by 3.0 and get 300 :)
Answer:
To write in standard form, we have to move the decimal point in 3.14 over 2 places to the left since our exponent is −2. This gives us our answer of 0.0314.

The Volume of cone in terms of π is: 8π in³.
What is the Volume of a Cone?Volume of any cone with radius, r, and height, h, is determined using the formula: V = 1/3πr²h.
Given:
Radius (r) = 2 in.Height (h) = 6 in.Thus:
Volume of cone = 1/3(π × 2² × 6)
Volume of cone = 1/3(24π)
Volume of cone = 8π in³.

The line plot below shows the number of kilometers Carson biked each day for 14 days. Does one measure describe the data better than the other? Explain
Answer:
It depends on the description you want to make. If you want to describe how separate is the data, then you would use a variation measure like a standard deviation which will compare each data with the mean.
On the other hand, if you want to measure how close the data is, then you would use central measures, like the mean or median, that will tell you the central value the whole data is pointing to.
Therefore, there's no bettter measures, it always depends on what aspect you want to highlight about the data set.
find the missing angle in the triangle
Answer:
60
Step-by-step explanation:
Since all of the sides of this triangle are shown to be congruent, this must be an equilateral triangle. In an equilateral triangle, all of the angles are equal to 60 degrees. Therefore, x is 60. Hope this helps!
Answer:
60
Step-by-step explanation:
If all sides all have the same angles then we will divide 180 by 3 which will give us our answer 60.

Which expression is equivalent to 36a minus 27?
9 (4a minus 3)
3 (18a minus 9)
9 (4a minus 27)
3 (12a minus 6)
Answer:
It's the first expression
Step-by-step explanation:
9 (4a minus 3)
(9x4a)-(9x3)
36a minus 27
The correct expression equivalent to 36a minus 27 is 9(4a minus 3)
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, an expression is 36a minus 27, we need to find an expression equivalent to the given expression,
So, converting the expression into mathematical expression,
36a minus 27
= 36a-27
HCF of 36 and 27 is 9, so taking 9 common,
Therefore,
36a-27 = 9(4a-9)
We can write 9(4a-9) in statement,
9(4a-9) = 9(4a minus 3)
Hence, the correct expression equivalent to 36a minus 27 is 9(4a minus 3)

The height of an object launched upward from ground level is given by the function s(t) = -4.9t2 + 78.4t, where s(t) is the height in meters and t is the time in seconds. Arrange the time intervals in ascending order of the object's magnitude of average velocity over the interval.
Answer:
the distance of the object before it hits the ground after launch is t = 1.592 seconds
Step-by-step explanation:
The height of an object launched upward from ground level is given by the function s(t) = -4.9t² +7.8t
when the object reach the ground then s(t) = 0
So; -4.9t² +7.8t = 0
-4.9t² +7.8t + 0 = 0
By using the quadratic equation
[tex]\mathbf{\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}}[/tex]
where; a = -4.9 ; b = 7.8 and c = 0
[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(7.8)^2-4(-4.9)(0)} }{2(-4.9)}}[/tex]
[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(60.84} }{-9.8}}[/tex]
[tex]\mathbf{=\dfrac{-(7.8) + \sqrt{(60.84} }{-9.8} \ \ \ \ OR \ \ \ \ \mathbf{\dfrac{-(7.8) - \sqrt{(60.84} }{-9.8}}}[/tex]
[tex]\mathbf{=0 \ \ \ OR \ \ \ 1.592 }}[/tex]

Jack has 20 unit cubes. How many rectangular prisms with different sized bases can he build with the cubes?
Answer:
Jack can form four rectangular prisms with 20 unit cubes.
Step-by-step explanation:
Number of unit cubes Jack has = 20
Factors of 20 = 1, 2, 4, 5, 10, 20
The possible dimensions of a rectangular prism that can be formed by these unit cubes may be,
1 × 1 × 20 (One cube at the base)
1 × 2 × 10 (2 cubes at the base)
1 × 4 × 5 (4 cubes at base in a single row)
2 × 2 × 5 (4 cubes at the base with 2 cubes in length and 2 cubes in width)
Therefore, Jack can form four rectangular prisms with 20 unit cubes.
A family plan to catch a ferry and need to book in at 12:02 am. The journey to the ferry port will take 2 hours 45 minutes. What time should they leave home in order to get to the ferry port on time?
Answer:
9:17 P.M.
Step-by-step explanation:
If the drive is 2 hours and 45 minutes and they need to be there by 12:02 am, you subtract two hours from that number. This means that if the drive was only two hours, they would have to leave home at 10:02 pm. However, it is 45 minutes longer than that so you have to subtract 45 minutes from 10:02 pm which gets 9:17 pm. Hope this helps!
The volume of a cylinder is 40 ft which expression represents the volume of O.C. one with the same base and height as the cylinder
The volume of a cylinder is 40 ft which expression represents the volume of a Cone with the same base and height as the cylinder?
3(40) ft³
3(1/40) ft³
1/3(40)ft³
1/3(40²) ft³
Answer:
The expression that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³
Step-by-step explanation:
To find the expression that represents the volume of a cone with the same height and base as the cylinder, we will follow the steps below:
First write down the formula for calculating volume of a cone and volume of a cylinder
volume of a cone = [tex]\frac{1}{3}[/tex] πr²h
volume of a cylinder = πr²h
If the base are the same, this implies they have the same radius, and from the question, it states that they have the same height, hence;
volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)
from the question, the volume of the cylinder is 40 ft³
volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)
= [tex]\frac{1}{3}[/tex] (40) ft³
volume of a cone = [tex]\frac{1}{3}[/tex] (40) ft³
Therefore the expression that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³
