find the first derivative with respect to x of the following function: f(x)=(7x+3)(4-3x)
Answer:
19 - 42x
Step-by-step explanation:
To differentiate this, we must use the product rule
f'(x) = (7x+3)'(4-3x) + (4-3x)'(7x+3)
= (7)(4-3x) + (-3)(7x+3)
= 28 - 21x - 21x - 9
= 19 - 42x
A lighthouse is located on an island 350 feet from the shore of the mainland as shown. If x=0.41 rad, what is D?
Now, let X= 0.41
Answer: d = 382

Work Shown:
d = 350*sec(x)
d = 350*(1/cos(x))
d = 350*(1/cos(0.41))

What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
We know a relation is a function if it is one-to-one or many-to-one.
But a relation one to many implies one input corresponds to two different outputs is not a function.
From the graph the function two different outputs 4 and 6 correspond to the same input 7.

Elam can wire a light in 40
minutes. Michael can wire a
light in 60 minutes. How long
would it take them to wire the
light together?
Answer:
24 minutes
Step-by-step explanation:
We use 1/a + 1/b = 1/c
where a and b are the individual times and c is the time together
1/40 + 1/60 = 1/c
Multiply each side by 120c
120c( 1/40 + 1/60 = 1/c)
3c + 2c = 120
5c = 120
Divide each side by 5
5c/5 = 120/5
c = 24
Answer: 24 minutes
Step-by-step explanation: To solve this kind of a problem which is called a work problem, it's important to understand the following idea.
Since Elam can wire a light in 40 minutes, we know that in 1 minute,
Elam can wire 1/40 of the light and in 2 minutes, Elam can wire 2/40 of it.
Therefore, in t hours, Elam can wire t/40 of the light.
The same applies for Michael, in t hours, he can wire t/60 of the light.
So to solve the problem, we use the following formula:
Part of job done by Elam + part of job done Michael = 1 job done
The part of the job done by Elam is t/40 and t/60 for Michael.
So we have t/40 + t/60 = 1.
Now multiply both sides by 120 to get 3t + 2t = 120
or 5t = 120 so t = 24.
So it takes 24 minutes if they work together.
Sandra's goal is to make at least $300 a week at her summer job. She made $76 on Monday and she makes $8 an hour. Write an inequality to represent the hours Sandra needs to work to meet her goal of making Atleast 300$ a week. How many hours does she need to work this week to make at least 300? ANSWER ASAP
76 + 8x ≥ 300
The inequality is shown above, to solve, you would first need to subtract 76 on both sides you should have 8x ≥ 224 left, proceed to divide by 8 on both sides. The answer should be x ≥ 28
Trees in a landscaping company's warehouse are being sold at a monthly rate of 7.3%. This situation can be modeled by an exponential function. The warehouse initially contained 45,000 trees.
Which function can be used to find the number of trees in the warehouse at the end of m months?
An exponential function can be used to calculate the number of trees in the warehouse at the end of any given number of months. This function uses the initial number of trees in the warehouse and the rate of 7.3% to determine the result.
What is function?A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. As you already know, C programming is built around functions. All C programs have at least one function, which is main(). A function is a group of statements that together perform a task. Every C program has at least one function, main(), and all the other functions are called user-defined functions.
The function that can be used to find the number of trees in the warehouse at the end of m months is an exponential function given by:
N(m) = 45,000(1.073)^m
Where N(m) is the number of trees in the warehouse at the end of m months and 45,000 is the initial number of trees in the warehouse. The rate of 7.3% is represented by 1.073, which is the base of the exponential function.
For example, if we want to find the number of trees in the warehouse at the end of 5 months, we can substitute m = 5 into the exponential function and calculate the result. This gives us N(5) = 45,000(1.073)^5 = 60,731. Thus, the warehouse will contain 60,731 trees at the end of 5 months.
In conclusion, an exponential function can be used to calculate the number of trees in the warehouse at the end of any given number of months. This function uses the initial number of trees in the warehouse and the rate of 7.3% to determine the result.

r=3 cm
Formulas for Spheres
S.A. = 41r2
V=far S.A. = [?] cm2
Round to the nearest tenth.
Answer: 113.0cm²
Step-by-step explanation:
The surface area if a square is calculated as:
= 4πr²
where, radius = 3cm
Surface area = 4πr²
= 4 × 3.14 × 3²

= 113.0cm²
Therefore, the surface area is 113.0cm²
Jose can spend a maximum of $225 from his birthday money. He bought an iPod for $199. Each song from iTunes costs $0.99 to download. Write an inequality that describes how many songs Jose can buy. (Do not solve the inequality.)
The inequality that describes how many songs Jose can buy is x ≤ 26.26
Define inequalityIn mathematics, an inequality is a statement that compares two values, expressing that one value is greater than, less than, or equal to the other. It uses inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to) to indicate the relationship between the two values.
Let x be the number of songs that Jose can buy.
The total amount Jose can spend is the sum of the cost of the iPod and the cost of the songs he buys, which must be less than or equal to his maximum budget of $225:
199 + 0.99x ≤ 225
This inequality can be simplified by subtracting 199 from both sides:
0.99x ≤ 26
Finally, we can isolate x by dividing both sides by 0.99:
x ≤ 26.26
So the inequality that describes how many songs Jose can buy is:
x ≤ 26.26

Use this formula to calculate compound interest:
Principal x (1 + Interest Rate)(Time)
$100
Interest Rate = 4%
Time= 5 years
Using the information above, how much money would you have after 5 years? Choose the answer that is closest to the exact answer.
The amount after 5 years on $100 using the compound interest is $122.
According to the question,
We have the following information:
Principal = $100
Interest Rate = 4%
Time= 5 years
We know that the following formula is used to find the total amount if there is compound interest:
Compound amount = \(P(1+\frac{r}{100})^{t}\) where P is the principal, r is interest rate and t is the time in years
(Note that there are different formulas for compound interest depending on how it is calculated.)
A = \(100(1+\frac{4}{100})^{5}\)
A = \(100(\frac{104}{100})^{5}\\100(1.04})^{5}\)
A = 100*1.22
A = $122
Hence, the amount after 5 years on $100 using the compound interest is $122.

Olivia measures the heights of two trees and the lengths of their shadows. She notices that the height of each tree and the length of its shadow are directly proportional. One of the trees has a height of 15 m and a 10 m long shadow. The other tree has a 14.4 m long shadow. Calculate its height, in metres (m). Give any decimal answers to 1 d.p. 15 m 10 m ? m 14.4 m
Step-by-step explanation:
directly proportional means
y = kx
with k being a constant factor for all values of x.
we get k by using the given data point (10, 15).
15 = k×10
k = 15/10 = 1.5
so, now for the other tree we know k and x and calculate y
y = 1.5×14.4 = 21.6 m
it is 21.6 m tall (its height is 21.6 m).
Determine whether the equation defines y as a function of x.
x+y=9 and x^2+y^2=1 and x=y^2
Answer:
Function: \(x+y=9\)
Not Function: \(x^2+y^2=1\) and \(x=y^2\)
Step-by-step explanation:
Given
\(x+y=9\)
\(x^2+y^2=1\)
\(x=y^2\)
Required
Determine if \(y\) is a function of \(x\)
Solving x+y=9
\(x+y=9\)
Make y the subject of formula
\(y = 9 - x\)
Hence; y is a function of x
Solving \(x^2+y^2=1\)
\(x^2+y^2=1\)
Subtract x² from both sides
\(y^2=1 - x^2\)
Square root of both sides
\(y =\± \sqrt{1 - x^2}\)
This implies that
\(y =\sqrt{1 - x^2}\) or \(y =-\sqrt{1 - x^2}\)
Because \(y\) can be any of those two expressions, it is not a function.
Solving \(x=y^2\)
\(x=y^2\)
Reorder
\(y^2 = x\)
Take square roots
\(y = \±\sqrt{x}\)
This implies that
\(y = \sqrt{x}\) or \(y = -\sqrt{x}\)
Because \(y\) can be any of those two expressions, it is not a function.
