Step-by-step explanation:
A cube has an edge of 3 feet. The edge is increasing at the rate of 4 feet per minute. Express the volume
of the cube as a function of m, the number of minutes elapsed.
Hint: Remember that the volume of a cube is the cube (third power) of the length of a side.
Answers
Answer:
so it increases by 4 per minute
the volume of a cube is v=side^3
so the side length be 5+4m where m is the number of minutes
therefor the volume can be expressed as V(m)=(5+4m)³
Step-by-step explanation:
The volume of the cube can be expressed as a function of m, the number of minutes elapsed as V(m) = (3 + 4m)³ feet³.
What do we mean by volume?The volume of an object is the total space occupied by the object in the three-dimensional space.
How do we solve the given question?In the question, we are asked to express the volume of a cube as a function of m, the number of minutes elapsed. We are given that the initial length of the edge of the cube was 3 feet, and it increases at a rate of 4 feet per minute.
∴ We can say that the length of the edge after m minutes = 3 + 4m
As 4 feet is the increase per minute and m minutes have elapsed.
We know, that the volume of a cube is the cube of the length of the edge.
∴ The volume = (3 + 4m)³.
Hence, the function of the volume of the cube in m can be written as,
V(m) = (3 + 4m)³ feet³.

Answers
We want to see the properties used to solve the given equation.
The properties used are:
Existence of the multiplicative inverse.Associative property of the multiplication.Let's write step by step and see which property we used on each step.
We start with:
[tex]\frac{4}{3} *(\frac{3}{4} *x) = \frac{4}{3} *\frac{1}{4}[/tex]
Now we use the associative property of the multiplication (says that we can multiply in any order we want) we rewrite this to:
[tex](\frac{4}{3} *\frac{3}{4} )*x = \frac{4}{3} *\frac{1}{4}[/tex]
Now we use the existence of the multiplicative inverse, this says that for a number a, there exist a number b such that:
a*b = 1
And we have that b = 1/a.
Then we apply that to the first factor to get:
[tex](\frac{4}{3} *\frac{3}{4}) *x = \frac{4}{3} *\frac{1}{4} \\\\x = \frac{4}{3} *\frac{1}{4}[/tex]
Again, using the same but with the numerator of the first factor of the right side and the denominator of the second factor of the right side we get:
[tex]x = \frac{4}{4} *\frac{1}{3} = \frac{1}{3}[/tex]

The solution is, the slope of the line below is 1/2.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
from the given graph, we get,
the line is passing through the points (-2, -3 ) and, (2, -1 )
now , we know that,
We can find the slope of a line given two points by using the following:
m = ( y2-y1)/(x2-x1)
so, substituting the values of the coordinates of the points,
we get,
m = -1 + 3 / 2 + 2
= 2 / 4
= 1/2
Hence, The solution is, the slope of the line below is 1/2.

If f(1)=6 and f(n) = F(n - 1) + 2 then find the value of f(4).
Answers
Hi there!
[tex]\large\boxed{f(4) = 12}[/tex]
We know that:
f(1) = 6
F(n) = F(n - 1) + 2 (Meaning, the next "n" is 2 added to the previous)
We can count up to f(4) using this logic:
f(2) = F(2 - 1) + 2 = F(1) + 2 = 6 + 2 = 8
f(3) = F(2) + 2 = 8 + 2 = 10
f(4) = F(3) + 2 = 10 + 2 = 12

The median annual salary for travel agents is P300,000. If the 80th percentile for the annual salary of a travel agent is P500,000, approximately what percent of the travel agents have annual salaries less than P300,000?

Using the percentile concept, it is found that 50% of travel agents have annual salaries less than P300,000.
In a data-set, if a measure is at the xth percentile, x% of the measures are less than x.The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.In this problem, the median is of P300,000, and thus, 50% of travel agents have annual salaries less than P300,000.

Ryan's error lies in not utilizing the right units for measurement. He used inadequate milk and wrong flour measurement, influencing the recipe's proportion and result.
How to explain Ryans' errorRyan's error lies in not utilizing the right units for measurement. The formula calls for 0.25 quart of drain and 2.5 glasses of flour. Ryan utilized 1/5 quart of drain (which is less than 0.25 quart), and rather than utilizing glasses for flour, he utilized 9/4 mugs (which is identical to 2.25 mugs, not 2.5 glasses).

The process of isolating the variable is the primary step involved in solving an equation.
Thus, option (B) is correct.
A) Substitution refers to the act of replacing a variable with a known value in an equation, which can be a useful strategy in some cases but is not a fundamental step in solving equations.
B) To solve an equation, it is necessary to perform operations that isolate the variable on one side of the equation and keep the other side free of the variable.
C)To verify if the obtained solution satisfies the original equation, but it is not a step required to solve the equation.
