cubic inches or inches³ would we use to describe the volume of a box measured in inches.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law
Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units.
As volume we measure by using three dimensions so the unit will be in cubics.
If we have to measure volume of box in inches then it will be cubic inches or inches³.
Hence cubic inches or inches³ units would we use to describe the volume of a box measured in inches.

Jessica is stacking items on a shelf. She has large books that weigh 5 pounds each and medium books that weigh 3 pounds each. The shelf should hold at most 50 pounds. Let x represent the number of large books. Let y represent the number of medium books. Which inequality represents this situation?
Answer:
5x + 3y ≤ 50
Step-by-step explanation:
Given,
The weight of each large book = 5 pounds,
And, the weight of each medium book = 3 pounds,
Thus,
The total weight in pounds of x large books and y medium books = x × weight of each large book + y × weight of each medium book
= 5x + 3y
According to the question,
Total weight ≤ 50 pounds
( Note : at most = less than equal )
⇒ 5x + 3y ≤ 50
Which is the required inequality.

What is the equation of a line that passes through the point (9, −3) and is parallel to the line whose equation is 2x−3y=6 ?
Enter your answer in the box
The equation of the line, in slope-intercept form, that is parallel to 2x - 3y = 6 and passes through (9, -3) is: [tex]\mathbf{y = \frac{2}{3}x - 9}[/tex]
Given:
Points the line passes through, (9, -3)
The equation of the line it is parallel to: 2x - 3y = 6
Note:
Parallel lines have the same slope valueEquation of a line in slope-intercept form is: y = mx + b. (m is slope; b is y-intercept)Point-slope form is; y - b = m(x - a)First, rewrite 2x - 3y = 6 in slope-intercept form to determine its slope.
[tex]2x - 3y = 6\\\\-3y = -2x + 6\\\\y = \frac{2}{3}x - 2[/tex]
The slope of 2x - 3y = 6 is therefore 2/3.Thus, the slope of the line that passes through (9, -3) is also 2/3.
Write the equation of the line in point-slope form:
Substitute m = 2/3, and (a, b) = (9, -3) into y - b = m(x - a)
Thus:[tex]y - (-3) = \frac{2}{3}(x - 9)\\\\y + 3 = \frac{2}{3}(x - 9)[/tex]
Rewrite in slope-intercept form[tex]y + 3 = \frac{2}{3}(x - 9)\\\\y + 3 = \frac{2}{3}x -\frac{2}{3}(9)\\\\y + 3 = \frac{2}{3}x - 6\\\\y = \frac{2}{3}x - 6 - 3\\\\\mathbf{y = \frac{2}{3}x - 9}[/tex]
Therefore, the equation of the line, in slope-intercept form, that is parallel to 2x - 3y = 6 and passes through (9, -3) is: [tex]\mathbf{y = \frac{2}{3}x - 9}[/tex]

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the population be = x
Let the number of years be time = t
Let the percentage of increase be = 5 %
Now , dx / dt = rate of increase of population per change in time
Here, ( dx/dt ) ∝ x
where , x is the population at any time t
Then ( dx/dt ) = Ax
where A is the proportionality constant.
Now , the equation is dx / x= A dt
On , Integrating with respect to x , we get
ln x = At + c
where c is the integration constant
So , on simplifying the equation , we get
Taking exponents on both sides of the equation ,
[tex]x=e^{rt + c}[/tex]
Let [tex]k=e^{c}[/tex]
So , the equation is
[tex]x= ke^{rt}[/tex]
Now , r is the rate of increase, and k is the initial population be x₀
And to find the time t taken to attain double population, so x = 2x₀
[tex]x= ke^{rt}[/tex]
Substituting the values in the equation , we get
[tex]2x_{0} =x_{0} e^{0.05t}[/tex]
[tex]2 = e^{0.05t}[/tex]
Taking logarithm on both sides,
[tex]ln 2=ln ( e^{0.05t} )[/tex]
0.69314=0.05t
t = 0.69317 / 0.05
t = 13.86294 years
Therefore , it takes 13.86294 years to double population
And , 13.86294 ≈ 14 years
Hence , The population of the country will double its population in approximately 14 years at a rate of 5 % growth rate every year

The 100-meter race times at a state track meet are normally distributed with a mean of 14.62 seconds and a standard deviation of 2.13 seconds. Using the Standard Normal Probabilities table, what is the approximate probability that a runner chosen at random will have a 100-meter time less than 15.5 seconds? a.0.1894
b. 0.3409
c. 0.6591
d. 0.7910
e. 0.8106
To solve this problem, we use the t statistic. The formula for z score is:
z = (x – u) / s
where x is the sample value = 15.5 seconds or below, u is the sample mean = 14.62 seconds, s is standard dev = 2.13 seconds
z = (15.5 – 14.62) / 2.13
z = 0.41
Using standard distribution tables at z = 0.41, the value of P is:
P = 0.6591 = 65.91%
Hence there is a 65.91% chance the runner will have less than 15.5 seconds of time

A ball is thrown vertically upward from the top of a 200 foot tower, with an initial velocity of 5 ft/sec. Its position function is s(t) = –16t2 + 5t + 200. What is its velocity in ft/sec when t = 3 seconds?
Answer:
The velocity would be - 91 ft/sec.
Step-by-step explanation:
Given,
The function that shows the position of the ball after t seconds,
[tex]s(t) = -16t^2 + 5t + 200[/tex]
Since, velocity is the changes in position with respect to time,
That is, if v(t) is the velocity of the ball after t second,
[tex]\implies v(t)=\frac{d}{dt}(s(t))[/tex]
[tex]=\frac{d}{dt}(-16t^2 + 5t + 200)[/tex]
[tex]=-32t+5[/tex]
Hence, the velocity after 3 seconds is,
[tex]v(3)=-32(3)+5=-96+5=-91\text{ ft per seconds}[/tex]

6a - 10 = 3a + 17 please explain how you got your answer
To solve the equation 6a - 10 = 3a + 17, we first move all 'a' terms to one side and constants to the other, then simplify and solve for 'a', resulting in a = 9.
The student has asked to solve the equation 6a - 10 = 3a + 17. To find the value of 'a', we need to consolidate all the 'a' terms on one side and the constants on the other side. Here's the solution step-by-step:
Subtract '3a' from both sides of the equation to get '6a - 3a - 10 = 17'.
Simplify the left side to get '3a - 10 = 17'.
Add '10' to both sides to isolate the 'a' term and get '3a = 17 + 10'.
Simplify the right side to get '3a = 27'.
Divide both sides by '3' to solve for 'a', getting 'a = 27 / 3'.
Finally, 'a = 9'.
The correct answer is a = 9.
Use the square root property of equality to solve (x – 3)2 = –4. The solutions are a. -1 or 7 b. 1 or 5 c. 3+- 2i d. 3+-4i
Answer:
The solution is 3 ± 2i . The correct option is C.
Step-by-step explanation:
using the square root property of equality to solve (x - 3)² = -4
we have;
(x - 3)² = -4
Take the square root of both-side
√(x - 3)² = ±√-4
x - 3 = ±√4 × √-1
Not that square root of -1 is i
x - 3 = ±2i
Add 3 to both-side of the equation
x -3 + 3 = 3 ± 2i
x = 3 ± 2i
Therefore, the solution are 3 ± 2i

1. The value -2 is a lower bound for the zeros of the function shown below. f(x)=4x^3-12x^2-x+15

2. Express the polynomial as a product of linear factors. f(x)=2x^3+4x^2-2x-4
A. (x-2)(x+1)(x-1)
B. (x-2)(x-2)(x-1)
C. (x-4)(x+1)(x-1)
D. 2(x+2)(x+1)(x-1)
It is true that the value -2 is a lower bound for the zeros of the function f(x) = 4x³ - 12x² - x + 15
The polynomial as a product of linear factors is d. 2(x+2)(x+1)(x-1)
How to determine the true statement
From the question, we have the following parameters that can be used in our computation:
f(x) = 4x³ - 12x² - x + 15
Also, we have
x =-2
Calculate f(-2)
f(-2) = 4(-2)³ - 12(-2)² - (-2) + 15
f(-2) = 4 * -8 - 12 * 4 + 2 + 15
f(-2) = -32 - 48 + 2 + 15
f(-2) = -63
The above value is negative
This means that -2 is a lower bound for the zeros of the function.
Expressing the polynomial as a product of linear factors.
Here, we have
f(x) = 2x³ + 4x² - 2x - 4
Factorize in 2's
So, we have
f(x) = 2x²(x + 2) - 2(x + 2)
This can be expressed as
f(x) = (2x² - 2)(x + 2)
Factor out 2
f(x) = 2(x² - 1)(x + 2)
Express as difference of two squares
f(x) = 2(x - 1)(x + 1)(x + 2)
Hence, the polynomial as a product of linear factors is d. 2(x+2)(x+1)(x-1)
