Answer:

50 + $5\sqrt{6}$ =

62.24744871

Step-by-step explanation:

10* 5 = 50

triangle 5^2 + x^2 = 7^2

x = $\sqrt{24 }$

area triangle = 1/2 * $\sqrt{24 }$ *5

$\sqrt{24} = 2\sqrt{6}$

area triangle = $5\sqrt{6}$

Sin (3x) dx = ? find the integral

AVprozaik [17]

Answer:

$\displaystyle \displaystyle \int {sin(3x)} \, dx = \frac{-cos(3x)}{3} + C$

General Formulas and Concepts:

Calculus

Antiderivatives - Integrals

Integration Constant C

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

Trig Integration: $\displaystyle \int{sin(x)} \, dx = -cos(x) + C$

U-Substitution

Step-by-step explanation:

Step 1: Define

$\displaystyle \int {sin(3x)} \, dx$

Step 2: Identify Substitution Variables

u = 3x

du = 3dx

Step 3: Integrate

[Integral] Rewrite: $\displaystyle \frac{1}{3}\int {3sin(3x)} \, dx$
[Integral] U-Substitution: $\displaystyle \frac{1}{3}\int {sin(u)} \, du$
[Integral] Trig Integration: $\displaystyle \frac{1}{3}[-cos(u)] + C$
[Expression] Multiply: $\displaystyle \frac{-cos(u)}{3} + C$
[Expression] Back-Substitute: $\displaystyle \frac{-cos(3x)}{3} + C$

£1700 is invested for 3 years at 4% per year SIMPLE interest. Work out the total interest

Crank

Answer:

$1912.27

Step-by-step explanation:

Simple interest rate formula: A = P(1 + r)^t

Simply plug in the known variables

A = 1700(1 + 0.04)³

A = 1700(1.04)³

A = 1700(1.12486)

A = 1912.27

PLEASE ELP ME ITS URGENT!!! 25 POINTS!!!!! Write 2.4 × 1012 in standard notation.

Svet_ta [14]

Answer:

2,400,000,000,000

Step-by-step explanation:

2.4 x 10^12 means that the decimal point is moved 12 places to the right (hence the power of 12)

So by moving the decimal point 12 times you get this: 2,400,000,000,000

The reason why there are only 11 zeroes is because the 4 was a decimal place to the right of 2, thus losing a zero.
