Answer:

-48.9582

Step-by-step explanation:

Given problem,

(-2.655) · (18.44)

Since, direct multiplication is quiet calculative,

Thus, for easing the calculation we simplify the expression,

(-2.655) · (18.44)

=\frac{-2655}{1000}\times \frac{1844}{100}

=-\frac{531}{200}\times \frac{461}{25}

=-\frac{531\times 461}{5000}

=-\frac{531(400+60+1)}{5000}

=-\frac{212400+31860+531}{5000}

=-\frac{244791}{5000}

=-\frac{244.791}{5}

=-48.9582

At the start of 2014, Mike's car is worth 12000. the car depreciates by 30 percent every year. how much is his car worth in 2017
Anarel [89]

Answer:

$4,116

Step-by-step explanation:

Worth of Mike's car at the start of 2014 = $12,000

If the car is said to depreciates every year by 30% = 30/100 = 0.3

The worth of the car at the start of 2017 is what we are to determine.

This means that the car depreciated by 30% (0.3) for 3 years since 2014 (2017 - 2014 = 3 yrs)

The worth at the start of 2017 would be calculated as follows:

12,000 × (1 - 0.3)³

= 12,000 × (0.7)³

= 12,000 × 0.343

= 4,116

Worth of the car at the start of 2017 would be $4,116

kogti [31]

Answer:

Rs.64

Step-by-step explanation:

<u>Amount of oranges:</u>

  • 150 kg

<u>Oranges sold:</u>

  • 150 - 18 = 132 kg

<u>Money made:</u>

  • 132* 80 = Rs. 10560

<u>Selling price of 150 kg:</u>

  • 10560/150 = Rs. 70.4

<u>Cost price:</u>

  • x+10% = 70.4
  • x*1.1= 70.4
  • x= 70.4/1.1
  • x= Rs.64
  • Cost price of oranges= Rs. 64

What is the binomial expansion of (x + 2)4? x4 + 4x3 + 6x2 + 4x + 1 8x3 + 24x2 + 32x x4 + 8x3 + 24x2 + 32x + 16 2x4 + 8x3 + 12x2
Margaret [11]

<u>Answer-</u>

\boxed{\boxed{(x+2)^4=x^4+8x^3+24x^2+32x+16}}

<u>Solution-</u>

Given expression is (x+2)^4

Applying Binomial Theorem

\left(a+b\right)^n=\sum _{i=0}^n\binom{n}{i}a^{\left(n-i\right)}b^i

Here,

a = x, b = 2 and n = 4

So,

\left(x+2\right)^4=\sum _{i=0}^4\binom{4}{i}x^{\left(4-i\right)}\cdot \:2^i

Expanding the summation

=\dfrac{4!}{0!\left(4-0\right)!}x^4\cdot \:2^0+\dfrac{4!}{1!\left(4-1\right)!}x^3\cdot \:2^1+\dfrac{4!}{2!\left(4-2\right)!}x^2\cdot \:2^2+\dfrac{4!}{3!\left(4-3\right)!}x^1\cdot \:2^3+\dfrac{4!}{4!\left(4-4\right)!}x^0\cdot \:2^4

=\dfrac{4!}{0!\left(4\right)!}x^4\cdot \:2^0+\dfrac{4!}{1!\left(3\right)!}x^3\cdot \:2^1+\dfrac{4!}{2!\left(2\right)!}x^2\cdot \:2^2+\dfrac{4!}{3!\left(1\right)!}x^1\cdot \:2^3+\dfrac{4!}{4!\left(0\right)!}x^0\cdot \:2^4

=1\cdot x^4\cdot \:1+4\cdot x^3\cdot \:2+6x^2\cdot \:4+4\cdot x\cdot \:8+1\cdot 1\cdot \:16

=x^4+8x^3+24x^2+32x+16
