Srekar needs to increase the length, width, and height of the prism below by 2 inches. The original prism has a length of 3 inches, a width of 2 inches, and a height of 1 inch.
A prism has a length of 3, height of 1, and width of 2.
Which statements about the new prism are true? Select three correct answers.
The new prism will have a length of 5 because 3 + 2 = 5.
The new prism will have a width of 4 because 2 + 2 = 4.
The new prism will have a height of 2 because 1 times 2 = 2.
The volume will increase by 6 because 2 times 3 = 6 and each of the 3 dimensions is increased by 2.
Srekar could increase the volume by the same amount by just adding 6 to the height instead of 2 to each side.
The volume of the new prism will be 20 times 3 = 60 because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each.
The statement first, statement second, and statement sixth are true.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have:
The original prism has a length of 3 inches, a width of 2 inches, and a height of 1 inches.
The new length = 3+2 = 5 inches
The new width = 2+2 = 4 inches
The new height = 1+2 = 3 inches
The volume of the old prism = 3×2×1 = 6 cubic inches
The volume of the new prism = 5×4×3 = 60 cubic inches
Srekar, could increase the volume by the same amount by just adding 6 to the height instead of 2 to each side is false becasue:
Volume = 3×2×(1+6) = 42 cubic inches
The volume of the new prism will be 20 times 3 = 60 because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each is true.
Thus, the statement first, statement second, and statement sixth are true.

This question is designed to be answered with a calculator. which inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve f(x) = 2 cos(2x) over the interval [0, pi/ 4] using 3 equal subdivisions?
a.) l < t < r
b.) r < l < t
c.) r < t < l
d.) t < r < l
The inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is C. r < t < l.
How to illustrate the inequality?From the information given, it should be noted that f'(x) is negative. Therefore, L > R. Also since f"(x) is negative, T > R.
f(x) = 2 cos 2x.
f'(x) = -4 sin 2x
f"(x) = -8 cos 2x
Therefore, the inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is r < t < l

a term salinity refers to the amount of salt in water. the salinity of earths oceans is about 525 grams of dissolved salt for evert 15 kilograms of water. find the grams of salt for every gram of ocean water
Answer:
0.035 grams
Step-by-step explanation:
Grams of salt per gram of ocean water
Divide the amount of salt by amount of water525 g / 15 kg525 g / 15000 g [∴1 kg = 1000 g]0.035 / 1For every gram of ocean water, there is 0.035 grams of salt dissolved in it.
The salinity of earths oceans,
→ a = 525 g
Amount of water for the salinity,
→ b = 15 kg
→ b = 15 × 1000
→ [ b = 15000 g ]
Then find the grams of salt for every gram of ocean water,
→ a ÷ b
→ 525 ÷ 15000
→ 0.035 g
Hence, answer is 0.035 grams of salt.

Mikayla is building a pyramid of paper cups. The bottom row has 61 cups while the top row has only one cup. If there are 16 total rows and the number of cups on each row represents an arithmetic sequence, find the total number of cups.
The number of cups will be equal to 496.
What is arithmatic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression
Here we have the data:-
The bottom row has 61 cups
If there are 16 total rows
The number of the cups will be calculated as:-
[tex]S_n=\dfrac{n(a_1+a_n)}{2}[/tex]
Here a1 is first term 1
an is last term 2
n is the total number of the rows
By putting the values in the question we will get:-
[tex]S_n=\dfrac{16(1+61)}{2}=\dfrac{16\times 62}{2}=496\ cups[/tex]
Hence the number of cups will be equal to 496.

A pie shop sells 32 apple pies, 33 pumpkin pie,20 cherry pies, and 15 chocolate pies.What percentage of pies were sold were apples or cherry
The percentage of pies sold that were apples or cherry is 52%
How to determine the percentage of apples or cherry?The given parameters are:
Apple = 32Pumpkin = 33Cherry = 20Chocolate = 15The total number of pies is:
Total = 32 + 33 + 20 + 15
Evaluate
Total = 100
The percentage of apples or cherry is calculated as:
Percentage = (Apple + Cherry)/Total
So, we have:
Percentage = (32 + 20)/100
Evaluate the quotient
Percentage = 0.52
Express as percentage
Percentage = 52%

Determine the zeros, sign and extreme values of the function y = -x³ + 8x²-16x.
Step-by-step explanation:
To find extreme values, take the first derivative
[tex]y = - 3 {x}^{2} + 16x - 16[/tex]
Solve the equation for x.
[tex]x = \frac{ - 16 + \sqrt{256 - 192} }{ - 6} [/tex]
or
[tex]x = \frac{ - 16 - \sqrt{256 - 192} }{ - 6} [/tex]
[tex]x = \frac{ - 16 + \sqrt{64} }{ - 6} [/tex]
or
[tex]x = \frac{ - 16 - \sqrt{64} }{ - 6} [/tex]
We then get
[tex]x = \frac{4}{3} [/tex]
or
[tex]x = 4[/tex]
So our extreme values occur at x=4/3 and x=4
Zeroes:
[tex] - {x}^{3} + 8 {x}^{2} - 16x[/tex]
[tex] - x( {x}^{2} - 8x + 16)[/tex]
[tex] - x(x - 4) {}^{2} [/tex]
[tex] - x = 0[/tex]
[tex](x - 4) {}^{2} = 0[/tex]
[tex]x = 4[/tex]
So we have a double root at 4, and a root of 0. We have two positive roots and one non negative root
End behavior:
Since we have a negative leading coefficient and a odd degree, as x becomes more positive, y will become negative and as x becomes more negative, y will become positive.

Remark
Since this is a multiple choice question, you need not worry excessively about solving the equation that sin(4x) and Cos(3x + 13) produce. It can be done, but you will spend a lot time and drink a lot of coffee doing it.
C
The wording of this problem is not the best. 13 is not in any way considered.
4x = 4*13 = 523x + 13 = 52.Not only are the two angles equal (52) but they add to 104 which is greater than 90.
11 is the next one you should look at
4*11 = 44
3*11 + 13 = 46
That gives you the right answer, but the question you have to ask yourself is are you answering the question? I don't think you are. The question is the number of degrees in the smaller angle. I think that means that you have already substituted a value for x.
I think the answer is C.

What is Line segment?Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.
Given that;
The coordinate are,
⇒ A = (- 5x, 4y)
⇒ B = (- 2x, - 4y)
Now,
Since, We know that;
The distance between the points (x₁ , y₁) and (x₂, y₂) is,
⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²
So, The distance between the points (- 5x, 4y) and (- 2x, - 4y) is,
⇒ d = √ (- 2x - (- 5x))² + (- 4y - 4y)²
⇒ d = √(3x)² + (- 8y)²
Thus, The values needed to find the length AB is find as;
⇒ AB = √(3x)² + (- 8y)²
