How to solve this problem

. 0.3 [1.57 – (0.6)²]

Answers

well (1.57- 0.6 X 0.6) x 0.3 = 0.363

You would have to solve -(0.6)^2
Then you distribute
0.3 times 1.57 minus whatever -(0.6)^2 is.
Then subtract and you get your answer

A company is planning to make a new kind of radio. The cost to produce x radios is C(x) = 80,000 + 10x. Meanwhile, the revenue earned by selling x radios is given by R(x) = 18x. If R < C, the company loses money. At what level of production does this happen?

Answers

$C(x) = 80,000 + 10x\ \ \ \wedge\ \ \ R(x) = 18x\n\nR < C\ \ \ \Leftrightarrow\ \ \ \ 18x<80,000+10x\n \n8x<80,000\ /:8\n \nx<10,000\n \nAns.\ The\ company\ loses\ money\ at\ level\ of\ production\ 10,000\ radios.$

What is the indefinite integral of 6sin(3t) dt?

Answers

Answer:

$\displaystyle \int {6sin(3t)} \, dt = -2cos(3t) + C$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Property [Multiplied Constant]: $\displaystyle (d)/(dx) [cf(x)] = c \cdot f'(x)$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Integration

Integrals
[Indefinite Integrals] Integration Constant C

Integration Property [Multiplied Constant]: $\displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx$

U-Substitution

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \int {6sin(3t)} \, dt$

Step 2: Integrate Pt. 1

[Integral] Rewrite [Integration Property - Multiplied Constant]: $\displaystyle \int {6sin(3t)} \, dt = 6\int {sin(3t)} \, dt$

Step 3: Integrate Pt. 2

Identify variables for u-substitution.

Set u: $\displaystyle u = 3t$
[u] Differentiate [Basic Power Rule, Multiplied Constant]: $\displaystyle du = 3 \ dt$

Step 4: integrate Pt. 3

[Integral] Rewrite [Integration Property - Multiplied Constant]: $\displaystyle \int {6sin(3t)} \, dt = 2\int {3sin(3t)} \, dt$
[Integral] U-Substitution: $\displaystyle \int {6sin(3t)} \, dt = 2\int {sin(u)} \, du$
[Integral] Trigonometric Integration: $\displaystyle \int {6sin(3t)} \, dt = -2cos(u) + C$
Back-Substitute: $\displaystyle \int {6sin(3t)} \, dt = -2cos(3t) + C$

Tom bought 2 1/16 pounds of peanuts and 2.45 pounds of cashews. Which did he buy more of?Explain.

Answers

2.45 pounds is more because that equals to a little over .40% more than 1/16 as a fraction which would be more over to the right making it a smaller digit
