Mathematics

I am Lyosha [343]3 years ago
5 0

Answer:

Step-by-step explanation

Step 1: multiply the coefficient a and the constant c. Given that the general expression of a parabolic equation is ax^2+bx+c

3*5=15

Step 2: examine the coefficient b and try to find 2 numbers which you can multiply to get 15, add or subtract and get - 8

In this Case: - 3*-5=15 and - 3+(-5)= - 8

Step3:

You separate the equation in terms of the two factors you have found

3x^2-3x-5x+5=0

Step 4:Factorise

3x(x-1)-5(x-1)=0

(3x-5)(x-1)=0

Multiply the weight in tonnes by the conversion factor ( 1 tonne = 1000 kg) to get the weight in kg's:

170 tonnes x 1000 = 170,000

Now convert to scientific notation, by moving the decimal point to have only 1 digit to the left of the decimal.

To do this, you would need to move the decimal 5 places to the left to get 1.70000

Now remove the 0's and multiply the number by 10 raised to the number of paces the decimal was moved to get:

1.7 x 10^5 kg's.
