A cell phone manufacturer designed the new packaging shown below that will hold a cell phone, accessories, and an owner's manual. Which is the volume of the new packaging? A small rectangular prism sitting on top of a larger rectangular prism. The top prism measures 5 inches by 1 inch by 2 inches. The bottom prism measures 5 inches by 4 inches by 1 plus 3 inches. 130 in.3 120 in.3 110 in.3 90 in.3
Answer:
90 inches³
Step-by-step explanation:
Given that:
A small rectangular prism sitting on top of a larger rectangular prism. The top prism measures 5 inches by 1 inch by 2 inches.
The bottom prism measures 5 inches by 4 inches by 1 plus 3 inches
Volume of rectangular prism = (width * length * height)
Volume of smaller prism: ( 5 * 1 * 2) inches = 10inch³
Volume of larger prism : (5 * 4 * (1 +3)) inches
(5 * 4 * (1 +3)) inches = (5 * 4 * 4) inches = 80 inches³
Total volume of the new packaging:
Volume of smaller + volume of larger prism
10 inches³ + 80 inches³ = 90 inches³
simply by distributing and combining like terms
-7(w-4)+3w-27

A company ships coffee mugs using boxes in the shape of cubes. The function g(x) = the cube root of x gives the side length, in inches, for a cube with a volume of x cubic inches. Suppose the company decides to double the volume of the box. Which graph represents the new function?
Step-by-step explanation:
Initially, let the side of the cubical box is [tex]a[/tex] inches,
So, the volume of the box, [tex]x = a \times a \times a= a ^3[/tex].
Given that [tex]g(x)=\sqrt[3]{x} =\sqrt[3]{a^3}[/tex]
[tex]\Rightarrow g(x)=a \; \cdots (i)[/tex]
On doubling the volume of the box, the new volume is [tex]2x[/tex].
So, [tex]g(x)=\sqrt[3]{2x} =\sqrt[3]{2a^3}[/tex]
[tex]\Rightarrow g(x)=\sqrt[3]{2} a \; \cdots (i)[/tex]
As [tex]\sqrt[3]{2} >1[/tex], so the graph of [tex]g(x)=\sqrt[3]{2} a[/tex] will be above of the [tex]g(x)=a[/tex] as shown in the graph.
What is the equation of the polynomial function?
Answer:
f(x) = (1/2)(x-2)^2(x+1)(x+2)
Step-by-step explanation:
You can determine this by looking at the zeroes of the graph. For any zero that goes through the x-axis, the power of that zero is odd. For any zero that that "bounces" from the x-axis, the power of that zero is even.
Starting from left to right, we can see that the first zero, -2, goes through the x-axis. That means (x+2) is raised to an odd power. The second zero, -1, also goes through, so (x+1) is raised to an odd power. The last zero, 2, bounces off the x-axis, so (x-2) is raised to an even power. The only functions that satisfy this criteria are function 1 and 2.
However, we are not done yet. We need to figure out which multiplier value (1/2, 1/4) is correct. To do this, we plug in 0 for x, since we know that the y-intercept is 4. When we plug in 0, we see that f(0) = 4 for the first function. Therefore, the first function is the answer.

The population of a small town can be described by the equation PN equals 4000+70n. Where n is the number of years after 2005. Explain in words what this equation tells us about how the population is changing.
Answer:
The current population (in 2005) is 4000 because it is the constant. The slope tells us how many people are added to the population, so 70 per year. For ex. 2008 (2008- 2005 = 3=> 3 x 70 = 210 => 210 + 4000 = 4210).
M is the midpoint of AB. If AM = 5x+10 & MB = 4x+16, find the value of AM
Answer:
[tex]AM =40[/tex]
Step-by-step explanation:
Given
[tex]AM = 5x + 10[/tex]
[tex]MB = 4x + 16[/tex]
Required
Determine AM
Since M is the midpoint, we have that;
[tex]AM = MB[/tex]
Substitute values for AM and MB
[tex]5x + 10 = 4x + 16[/tex]
Collect Like Terms
[tex]5x - 4x = 16 - 10[/tex]
[tex]x = 6[/tex]
To solve for AM; substitute 6 for x in [tex]AM = 5x + 10[/tex]
[tex]AM = 5 * 6 + 10[/tex]
[tex]AM =30 + 10[/tex]
[tex]AM =40[/tex]
The relationship between two variables is inverse when a decrease in one variable is associated with an increase in the other variable. A. False B. True
Answer: True
If one variable goes down, then the other goes up, and vice versa. Think of it like a see-saw. We'll have x on one side pushing down to make y go up. An example of this would be y = 1/x which graphs out a hyperbola.
The statement "two variables is inverse when a decrease in one variable is associated with an increase in the other variable." is True statement.
What is Inverse Proportion?One kind of proportionality relationship is inverse proportion. If two quantities are inversely related, one will increase while the other will decrease. Building a wall would be an example of an inverse proportion in action.
Given:
We know in direct relation if one quantity increase then another quantity increase.
and, in Inverse Relation if one quantity increase then other Quantity decrease.
So, two variables is inverse when a decrease in one variable is associated with an increase in the other variable is true statement.

The electrical resistance of a wire, R, varies directly as its length, L, and inversely as its cross sectional area, A. If the resistance of a wire is 0.08 ohm when the length is 100 ft and its cross-sectional area is 0.05 in^2 , what is the resistance of a wire whose length is 4000 ft with a cross-sectional area of 0.02in^2 ? a) Write the variation equation. (R=k(l/a) b) Determine the value of the quantity indicated. WILL MARK BRAINLIEST - 50PTS! NEED FAST - with work please so I understand how to do it, thank you:)
Step-by-step explanation:
(A)
Length of wire = 30.48 m
Area of cross section = 3.22 * 10 ^ -5 m^2
[tex]R = k \frac{l}{a} [/tex]
[tex]k = \frac{R \times a}{l} = \frac{0.08 \times 3.22 \times {10}^{ - 5} }{30.48} = 8.45 \times {10}^{ - 8} ohm \: m^{ - 1} [/tex]
(B) length of wire = 1219.2 m
Area of cross section = 1.29 * 10^-5 m^2
Resistance = 8.45 * 10^-8 * 1219.2 / 1.29 * 10^-5 = 7.98 Ohms

The numbers 21, 46, and 57 are composite numbers.
Given,
21, 46 and 57
We need to identify which are prime or composite numbers.
What are prime numbers and composite numbers?Prime number - The numbers whose factor is only 1 and itself.
Example: 2, 5, 7
2 x 1 = 2
5 x 1 = 5
7 x 1 = 7
Composite number - The numbers which have factors other than itself and 1.
Example: 4, 6, 8
4 = 2 x 2
6 = 2 x 3
8 = 2 x 4
Find the factors
21 - 7 x 3
46 - 2 x 23
57 - 3 x 19
We see that each number has factors other than 1 and itself.
So,
21, 46, and 57 are composite numbers.
Thus 21, 46, and 57 are composite numbers.

Consider the partial construction of a line parallel to liner through point Q.
What would be the final step in the construction?
Draw a line through P and S.
Draw a line through W and S.
Draw a line through Q and S.
Draw a line through T and S.
Answer:
Option (3)
Step-by-step explanation:
To construct a line parallel to the line through point Q we will follow the following steps,
1). We join two points P (on the line) and point Q above the line PT with the help of a straightedge.
2). Now we will copy the angle QPT at point P with the help of a compass (Arcs as shown in the figure)
3). Finally we will join points Q and S to construct a line QS parallel to the line PT.
Therefore, Option (3) will be the answer.

If f(x) = 5x + 40, what is f(x) when x = -5? 0 g -8 O 7 O 15
answer is 15
[tex]f(x)=5x+40\\f(-5)=5(-5)+40\\f(-5)=-25+40\\f(-5)=15[/tex]
If f(x) = 5x + 40, then the value of f(x) when x = -5 is: 15.
option D is correct.
Here, we have,
given that,
f(x) = 5x + 40
now, we have to find the value of f(x) when x = -5.
To find the value of f(x) when x = -5,
we substitute -5 into the function f(x) = 5x + 40:
we get,
f(-5) = 5(-5) + 40
= -25 + 40
= 15
Therefore, f(x) when x = -5 is 15.
Hence, If f(x) = 5x + 40, then the value of f(x) when x = -5 is: 15.
option D is correct.

Hey there! I'm happy to help!
We want to get m all by itself on one side of the equation. To do this, we use inverse operations on both sides of the equation to cancel out variables on one side to isolate m.
am/c=n
We multiply both sides by c.

Which equation describes a line that passes through (-6,8) and is perpendicular to the line described by y=2x-4
Step-by-step explanation:
Hey, there!!
The given is a point (-6,8) through which a line passes. And is perpendicular to the line y = 2x-4
The equation for point (-6,8) is,
(y-8)= m1(x+6)...........(i)
and given equation is y = 2x-4............(ii)
Now, from equation (ii).
slope (m2)= 2 { as equation (ii) is in the form of y= mx+c where m is a slope}.
Now, For perpendicular,
m1×m2= -1
m1×2= -1
[tex]m1 = \frac{ - 1}{2} [/tex]
Therefore, m1 = -1/2.
Putting, the value of m1 in equation (i).
(y-8) = -1/2×(x+6)
2(y-8)= -1(x+6)
2y - 16 = -x -6
x+2y-10 = 0......... is the required equation.

Explain why angle is considered a defined term in geometry.

Step-by-step explanation:
In Euclidean geometry there are three undefined terms: Points, line and plane. An angle is a defined term, since it is formed by two lines that intersects each other and are coplanar.
Express y in terms of x, given 2x+3y =4. Check whether the point (2,1) lies on the given line.
Answer:
see explanation
Step-by-step explanation:
Given
2x + 3y = 4 ( subtract 2x from both sides )
3y = - 2x + 4 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{4}{3}[/tex]
To determine if the point (2, 1) lies on the line, substitute x = 2 into the right side of the equation and if the value obtained equals the y- coordinate of the point then it lies on the line.
y = - [tex]\frac{4}{3}[/tex] + [tex]\frac{4}{3}[/tex] = 0 ≠ 1
Ths (2, 1) does not lie on the line
